piperidines and Fatigue

Excessive daytime sleepiness (EDS) and fatigue are major complaints in patients with obstructive sleep apnoea (OSA) syndrome. Pitolisant is an orally active selective histamine H3 receptor (H3R) antagonist/inverse agonist, which enhances histaminergic transmissions in the brain and thereby elicits strong wake-promoting effects. This article assesses the efficacy and safety of pitolisant 20 mg in patients with OSA, based on existing randomised controlled studies.. An individual patient data (IPD) meta-analytical two-level (study-patient) hierarchical model was used assuming a random treatment effect. The Epworth Sleepiness Scale (ESS) and Oxford Sleep Resistance (OSleR) tests were co-primary endpoints.. A total of 512 patients, including 384 treated with pitolisant and 128 with placebo, were included in the analysis. Compared with placebo, pitolisant reduced mean ESS by - 3.1 (95% CI [- 4.1; - 2.1]; p < 0.001) and improved OSleR by 1.18 (1.02; 1.35, p = 0.022); 30% more patients had reduced fatigue (risk ratio [RR] = 1.3, [1.11; 1.53]), p = 0.001) and 46% more patients had improved Clinical Global Impression (CGI) (RR = 1.46 [1.12; 1.89], p = 0.005). No significant differences in safety endpoints were found. These results proved homogeneous across studies and subgroups of the population.. The results provide evidence of a significant benefit of pitolisant in improving EDS and fatigue, irrespective of baseline conditions.

Fatigue is a common and debilitating symptom in patients with RA. Since 2007, fatigue has been included as one of the core outcome measures in RA. Clinical trials of biologic DMARDs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) have included fatigue as a secondary endpoint. A Cochrane review in 2016 concluded that the bDMARDs have a moderate effect on improving fatigue in RA. More recent clinical trials of the new biologic agent sarilumab and the Janus kinase inhibitors tofacitinib and baricitinib showed similar benefits. It remains unclear whether the effect of bDMARDs and tsDMARDs on fatigue is mediated by direct effects or through a reduction in inflammation. As fatigue was a secondary endpoint, many analyses did not adjust for potential confounding factors, including pain, mood and anaemia, which is a significant limitation.

Ibrutinib is indicated in Europe for the treatment of several B-cell malignancies, including chronic lymphocytic leukaemia (CLL). However, despite the high efficacy and favourable toxicity profile of ibrutinib, recent data suggest that it is not always administered optimally in clinical practice, with an increased tendency for dose reduction and a higher frequency of discontinuation. An expert panel of European haematologists was convened to identify practical issues pertinent to physicians involved in the therapeutic management of ibrutinib-treated CLL patients and here we outline the findings. Practical management recommendations are given for treating patients with ibrutinib and clinical considerations for the management of adverse events (AEs) that can be associated with ibrutinib treatment are addressed. This article highlights that patients should be monitored for treatment emergent adverse events, most of which are mild, transient and generally occur early in therapy and that, even with more challenging AEs, patients can often be maintained on therapy with minimal disruption through careful management. The necessity to use the correct ibrutinib dose, along with increased awareness, vigilance, mitigation and management of AEs, are all recommended to maximise outcomes for CLL patients treated with ibrutinib.

Angiogenesis inhibition is a major antitumor strategy that has emerged during the last decade. Oral tyrosine kinase inhibitors (TKI) targeting the VEGF receptor, including sunitinib, sorafenib, axitinib, regorafenib, pazopanib, and vandetanib reduce tumor growth and metastasis. These agents are approved for the treatment of metastatic diseases in first or second-line. They display a narrow therapeutic index. However, data in the elderly and/or in patients with multiple illnesses remain scarce. This population is classically excluded from clinical trials. The aim of this review is to provide an overview of existing literature regarding antiangiogenic TKI tolerance in the elderly (>70 years old). We also highlight key points of the pre-therapeutic evaluation and summarize the management of common toxicities.

The efficacy of combined vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) inhibition in patients with advanced non-small-cell lung cancer (NSCLC) was well studied. However, few studies focused on the risk and adverse events (AEs) of combined targeted therapy. The aim of this meta-analysis was to evaluate the safety profile of combined targeted therapy against EFGR and VEGF in patients with advanced NSCLC. A comprehensive literature search in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ASCO Abstracts and ESMO Abstracts was conducted. Eligible studies were randomized clinical trials (RCTs) that compared safety profile of combined therapy inhibiting EFGR and VEGF pathways with control groups (placebo, single EGFR or VEGF inhibition therapy, chemotherapy or a combination of them) in patients with advanced NSCLC. The endpoints included treatment discontinuation, treatment-related deaths and AEs. The search identified 15 RCTs involving 6,919 patients. The outcomes showed that three of four pairwise comparisons detected more discontinuation due to AEs in combined targeted therapy, with odds ratio (OR) compared with the control groups ranged from 1.97 to 2.29. Treatment with combined inhibition therapy was associated with several all-grade and grade 3 or 4 AEs (e.g. rash, diarrhea and hypertension). Also, there was a significantly higher incidence of treatment-related deaths in combined inhibition using vandetanib versus single EGFR inhibition therapy (OR = 1.97, 95% CI 1.19-3.28). In conclusion, combined inhibition therapy against EGFR and VEGF in patients with advanced NSCLC was associated with increased toxicity. Increased AEs hinder patient compliance and reduce their quality of life, leading to dose reduction or discontinuation.

The effective anti-migraine drugs triptans, all bind with high affinity to three serotonin (5-HT) subtypes, the 5-HT1B, 5-HT1D and 5-HT1F. 5-HT1B mRNA is densely localized within smooth muscle, and less in the endothelium of cerebral blood vessels. This vascular distribution of 5-HT1B receptor has been shown to mediate the vasoconstrictive properties of the triptans, responsible for potential cardiac adverse events. Activation of 5-HT1D subtype, although effective in animal models of migraine, was not enough efficient to attenuate migraine attacks in clinical trials. The 5-HT1F receptor is located both in vessels and within the trigeminal ganglion (TG) and the trigeminal nucleus caudalis (Sp5C), but with the difference that the 5-HT1F receptor lack vasoconstrictive properties, making it an attractive target for new anti-migraine drugs. Selective activation of 5-HT1F receptor potently inhibited markers associated with electrical stimulation of the TG. Thus 5-HT1F receptor represents an ideal target for anti-migraine drugs. So far two selective 5-HT1F agonists have been tested in human trials for migraine: LY334370 and lasmiditan. Both molecules were efficient in attenuating migraine attacks with efficacy in the same range as oral sumatriptan 100mg, the gold standard for triptans. The LY334370 project withdrew because of toxicity in animals, while lasmiditan is still testing. In this review we present all the available preclinical and clinical data on the 5-HT1F agonists as a potential new class of anti-migraine drugs lacking vascular activity and we discuss related issues on the vascular and neuronal aspects of migraine pathogenesis.

To review preclinical and clinical information on flavopiridol, an inhibitor of cyclin-dependent kinases (CDKs), tested as an antitumor agent.. Primary and review articles were identified by MEDLINE search (1990-June 2001). Abstracts from recent meetings were also used as source materials.. Flavopiridol was reviewed with regard to its mechanisms, preclinical and clinical results, pharmacokinetics, and metabolism.. Flavopiridol is an inhibitor of several CDKs and displays unique anticancer properties. In addition to direct CDK inhibition, flavopiridol also exhibited other features such as inducing apoptosis in many cancer cell lines, decreasing cyclin D1 concentration, and inhibiting angiogenesis. Preclinical xenograft models showed significant antitumor activity for flavopiridol. The regimen using 72-hour continuous infusion every 2 weeks has been most extensively applied in clinical trials, with a 1-hour infusion currently being explored to achieve higher peak concentrations. Several Phase I and II trials have been reported, with some evidence of antitumor activity noted. Further Phase I and II trials using flavopiridol as a single agent and in combination with standard chemotherapeutic regimens and various tumor types are ongoing.. Flavopiridol is the first CDK inhibitor to enter clinical trials. Several Phase I and Phase II clinical trials with different regimens (72-h or 1-h infusion) have been completed. Initial clinical trials have been intriguing, but many questions remain: What is the best regimen (< or =72-h infusion)? Does optimal future development of this drug depend on the combination with other chemotherapy? What is the best combination of flavopiridol with other chemotherapy?

Fatigue, a common symptom of rheumatoid arthritis (RA), is detrimental to health-related quality of life (HRQoL). We evaluated the impact of tofacitinib on fatigue, sleep, and HRQoL and explored associations between fatigue, related patient-reported outcomes (PROs), and disease activity in RA patients.. This post hoc analysis pooled data from three Phase 3 studies of tofacitinib (ORAL Scan; ORAL Standard; ORAL Sync) in RA patients. Patients received tofacitinib 5 or 10 mg twice daily, placebo, or adalimumab (active control; ORAL Standard only, not powered for superiority) with conventional synthetic disease-modifying antirheumatic drugs. Assessed through Month (M)12 were changes from baseline in disease activity, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Medical Outcomes Study Sleep scale (MOS-SS), and Short Form-36 Health Survey (SF-36) composite/domain scores, and proportions of patients reporting improvements from baseline in FACIT-F total and SF-36 domain scores ≥ minimum clinically important differences (MCIDs) or ≥ population normative values. Pearson correlations examined associations among PROs at M6. Treatment comparisons were exploratory, with p < 0.05 considered nominally significant.. Generally, active treatment led to significant improvements from baseline in FACIT-F total, and MOS-SS and SF-36 composite/domain scores vs placebo, observed by M1 and maintained through M6 (last placebo-controlled time point). Through M6, more patients achieved improvements from baseline ≥ MCID and achieved scores ≥ population normative values in FACIT-F total and SF-36 domain scores with tofacitinib vs placebo. Through M12, some nominally significant improvements with tofacitinib vs adalimumab were observed. With active treatment at M6, FACIT-F scores were moderately (0.40-0.59) to highly (≥ 0.60) correlated with SF-36 composite/domain scores (particularly vitality), moderately correlated with most MOS-SS domain scores, and highly correlated with MOS-SS Sleep Problems Index I scores. Disease activity correlations were moderate with FACIT-F scores and low (0.20-0.39) to moderate with SF-36 general health domain/composite scores.. Tofacitinib and adalimumab generally conferred significant, clinically meaningful improvements in fatigue, sleep, and HRQoL (including vitality) vs placebo through M6, with improvements maintained to M12. M6 correlations between FACIT-F, PROs of sleep, HRQoL, and disease activity underscore the interrelatedness of multiple PROs and disease activity in RA..

Ankylosing spondylitis (AS) impacts quality of life. We assessed patient-reported outcomes (PROs), pain, fatigue, health-related quality of life (HRQoL) and work productivity in a phase III trial of tofacitinib.. Adults with AS and with inadequate response/intolerance to ≥2 non-steroidal anti-inflammatory drugs received tofacitinib 5 mg twice daily or placebo for 16 weeks. Afterwards, all received open-label tofacitinib until week 48. Change from baseline to week 48 was determined for PROs: total back pain; nocturnal spinal pain; Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) overall spinal pain (Q2); Functional Assessment of Chronic Illness Therapy-Fatigue; BASDAI fatigue (Q1); AS Quality of Life (ASQoL); Short Form-36 Health Survey Version 2 (SF-36v2); EuroQoL-Five Dimension-Three Level health profile and Visual Analogue Scale; and the Work Productivity and Activity Impairment (WPAI) questionnaire. Improvements from baseline ≥minimum clinically important difference, and scores ≥normative values at week 16 were evaluated.. In 269 randomised and treated patients, at week 16, there were greater least squares mean improvements from baseline with tofacitinib 5 mg twice daily versus placebo in BASDAI overall spinal pain (-2.85 vs -1.34), BASDAI fatigue (-2.36 vs -1.08), ASQoL (-4.03 vs -2.01) and WPAI overall work impairment (-21.49 vs -7.64) (all p<0.001); improvements continued/increased to week 48. Improved spinal pain with tofacitinib was seen by week 2. Patients receiving tofacitinib reported clinically meaningful PRO improvements at week 16. Percentages with PRO scores ≥normative values at week 16 were greater with tofacitinib in SF-36v2 Physical Component Summary, physical functioning and bodily pain domains (p≤0.05).. In patients with AS, treatment with tofacitinib 5 mg twice daily resulted in clinically meaningful improvements in pain, fatigue, HRQoL and work productivity versus placebo to week 16, which were sustained to week 48.. NCT03502616.

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We examined the degree to which Patient Global Assessment of Disease Activity (PtGA) was driven by patient-reported assessments of pain (Pain), physical function, and fatigue in patients receiving tofacitinib 5 mg twice daily or placebo, each with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs).. This post hoc analysis used data pooled from three randomized controlled trials in csDMARD-inadequate responder (csDMARD-IR) patients (ORAL Scan: NCT00847613; ORAL Standard: NCT00853385; ORAL Sync: NCT00856544). Using subgroup analysis from 2 × 2 tables, associations between PtGA and Pain, Health Assessment Questionnaire-Disability Index (HAQ-DI), and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) at month 3 were evaluated using Pearson's Phi correlation coefficients. To support the main analysis, associations between select patient-reported outcomes (PROs) were also evaluated in csDMARD-naïve (ORAL Start; NCT01039688) and biologic (b)DMARD-IR (ORAL Step; NCT00960440) patients.. Across csDMARD-IR treatment groups, low disease activity (defined as PtGA ≤ 20 mm), and moderate (≥ 30%) and substantial (≥ 50%) improvements from baseline in PtGA were associated with mild Pain (Visual Analog Scale score ≤ 20 mm), and moderate (≥ 30%) and substantial (≥ 50%) improvements from baseline in Pain; lack of Pain improvement was associated with little/no improvement in PtGA. In contrast, large proportions of csDMARD-IR patients who reported PtGA improvements did not report HAQ-DI or FACIT-F scores ≥ normative values (≤ 0.25 and ≥ 43.5, respectively) or changes in HAQ-DI or FACIT-F scores ≥ minimum clinically important difference (≥ 0.22 and ≥ 4.0, respectively). Generally, PtGA and Pain outcomes were moderately-to-strongly correlated at month 3 in csDMARD-IR patients, with weaker correlations evident between PtGA and HAQ-DI/FACIT-F outcomes. Similar findings were generally evident in csDMARD-naïve and bDMARD-IR patients.. This analysis supports the role of Pain as a key driver of PtGA in RA; physical function and fatigue play lesser roles in patients' perceptions of disease activity. These findings corroborate the importance of improved PROs and attainment of low symptom states for optimizing patient care..

We assessed the safety profile of lasmiditan, a selective 5-HT. SAMURAI and SPARTAN were Phase 3 double-blind studies of patients with migraine, randomized to oral lasmiditan 50 mg (SPARTAN only), 100 mg, 200 mg, or placebo to be taken within 4 hours of onset of migraine pain. Safety data from the studies were integrated. Treatment-emergent adverse events (occurring within 48 hours of first dose) were considered in the analyses.. The safety population comprised 1262 patients assigned placebo, and 654, 1265, and 1258 assigned lasmiditan 50 mg, 100 mg, and 200 mg, respectively. There were no deaths; serious adverse events were reported for seven patients (placebo, n = 2 [0.2%]; lasmiditan 50 mg, n = 1 [0.2%]; lasmiditan 100 mg, n = 1 [0.2%]; lasmiditan 200 mg, n = 3 [0.2%]). Patients reporting ≥ 1 treatment-emergent adverse events were: Placebo, n = 174 (13.5%); lasmiditan 50 mg, n = 166 (25.4%); lasmiditan 100 mg, n = 458 (36.2%); and lasmiditan 200 mg, n = 510 (40.6%). Treatment-emergent adverse events were generally mild or moderate in severity. The most common treatment-emergent adverse events with lasmiditan were dizziness, paresthesia, somnolence, fatigue, nausea, muscular weakness and hypoesthesia. There were no ischemic events.. As a centrally-penetrant drug, lasmiditan use was associated with neurologic treatment-emergent adverse events; most were mild or moderate in severity and self-limiting..

Ibrutinib, a first-in-class once-daily oral Bruton tyrosine kinase inhibitor indicated for chronic lymphocytic leukemia (CLL), is continued until progressive disease or unacceptable toxicity. We conducted an integrated safety analysis of single-agent ibrutinib from randomized phase 3 studies PCYC-1112 (RESONATE, n = 195) and PCYC-1115/1116 (RESONATE-2, n = 135), and examined longer-term safety separately in the phase 1b/2 PCYC-1102/1103 study (n = 94, 420 mg/d). In the integrated analysis (ibrutinib treatment up to 43 months), the most common adverse events (AEs) were primarily grade 1/2; diarrhea (n = 173, 52% any-grade; n = 15, 5% grade 3) and fatigue (n = 119, 36% any-grade; n = 10, 3% grade 3). The most common grade 3/4 AEs were neutropenia (n = 60, 18%) and pneumonia (n = 38, 12%). Over time, prevalence of AEs of interest (diarrhea, fatigue, grade ≥3 infection, bleeding, and neutropenia) trended down; prevalence of hypertension increased, but incidence decreased after year 1. AEs led to dose reductions in 42 (13%) patients and permanent discontinuations in 37 (11%); dose modifications due to AEs were most common during year 1 and decreased in frequency thereafter. The most common AEs (preferred term) contributing to discontinuation included pneumonia (n = 4), anemia (n = 3), and atrial fibrillation (n = 3). With long-term follow-up on PCYC-1102/1103 (ibrutinib treatment up to 67 months), grade 3/4 AEs were generally similar to those in the integrated analysis. Overall, AEs were primarily grade 1/2 and manageable during prolonged ibrutinib treatment in patients with CLL. These trials were registered at www.clinicaltrials.gov as #NCT01578707, #NCT01722487, #NCT01724346, #NCT01105247, and #NCT01109069.

Health-related quality of life (HRQoL) is an important endpoint, especially in clinical trials for malignancies with a long course of disease, such as chronic lymphocytic leukemia (CLL). Patient-reported outcomes were examined in the randomized, double-blind, placebo-controlled HELIOS study to assess the impact of treatment with the Bruton's tyrosine kinase inhibitor ibrutinib, added to bendamustine plus rituximab (BR) background therapy. Measures included FACIT-Fatigue, EORTC QLQ-C30, QLQ-CLL16, and EQ-5D-5L. Of 578 patients enrolled, 540 (93%) provided FACIT-Fatigue responses at baseline. Most had only a moderate degree of impairment at baseline; mean values did not appear to change over time in either treatment arm, suggesting that adding ibrutinib to BR did not impact health-related quality of life. However, post-hoc analyses showed that subgroups of patients with the worst fatigue, physical functional status, and well-being at baseline had greater improvements in these outcomes with ibrutinib plus BR treatment versus placebo.

Checkpoint kinase 1 (Chk1) inhibition following chemotherapy-elicited DNA damage overrides cell cycle arrest and induces mitotic catastrophe and cell death. GDC-0575 is a highly-selective oral small-molecule Chk1 inhibitor that results in tumor shrinkage and growth delay in xenograft models. We evaluated the safety, tolerability, and pharmacokinetic properties of GDC-0575 alone and in combination with gemcitabine. Antitumor activity and Chk1 pathway modulation were assessed.. In this phase I open-label study, in the dose escalation stage, patients were enrolled in a GDC-0575 monotherapy Arm (1) or GDC-0575 combination with gemcitabine Arm (2) to determine the maximum tolerated dose. Patients in arm 2 received either i.v. gemcitabine 1000 mg/m2 (arm 2a) or 500 mg/m2 (arm 2b), followed by GDC-0575 (45 or 80 mg, respectively, as RP2D). Stage II enrolled disease-specific cohorts.. Of 102 patients treated, 70% were female, the median age was 59 years (range 27-85), and 47% were Eastern Cooperative Oncology Group PS 0. The most common tumor type was breast (37%). The most frequent adverse events (all grades) related to GDC-0575 and/or gemcitabine were neutropenia (68%), anemia (48%), nausea (43%), fatigue (42%), and thrombocytopenia (35%). Maximum concentrations of GDC-0575 were achieved within 2 hours of dosing, and half-life was ∼23 hours. No pharmacokinetic drug-drug interaction was observed between GDC-0575 and gemcitabine. Among patients treated with GDC-0575 and gemcitabine, there were four confirmed partial responses, three occurring in patients with tumors harboring TP53 mutation. Pharmacodynamic data were consistent with GDC-0575 inhibition of gemcitabine-induced expression of pCDK1/2.. GDC-0575 can be safely administered as a monotherapy and in combination with gemcitabine; however, overall tolerability with gemcitabine was modest. Hematological toxicities were frequent but manageable. Preliminary antitumor activity was observed but limited to a small number of patients with a variety of refractory solid tumors treated with GDC-0575 and gemcitabine.. NCT01564251.

The main objective of this study was to investigate the tolerability and safety of the monoaminergic stabilizer (-)-OSU6162 in patients with multiple sclerosis (MS). In addition, a potential therapeutic effect of (-)-OSU6162 with focus on MS-related fatigue was estimated by means of various self-assessment rating scales as well as a clinical investigator-rated scale.. In this open-label, single-arm study, 30 MS patients received treatment with the monoaminergic stabilizer (-)-OSU6162 during 12 weeks. The dose of (-)-OSU6162 was 15 mg twice daily during the first 4-week period, up to 30 mg twice daily during the second 4-week period and up to 45 mg twice daily during the third 4-week period, with follow-up visits after 16 and 20 weeks. MS-related fatigue was rated by the clinical investigator or by self-assessments, using mainly established rating scales. Twenty-five patients completed the study.. (-)-OSU6162 was well tolerated by all patients, and no serious adverse events were observed. Therapeutically, improvements were observed with respect to fatigue and mood, as judged by ratings on the Mental Fatigue Scale (MFS), Short Form-36 (SF-36) scale and Beck Depression Inventory (BDI). Furthermore, the large majority of patients were rated as globally improved in the medical observers' rating scale Clinical Global Impression of Change (CGI-C).. In view of its good tolerability, (-)-OSU6162 may offer a new treatment option for alleviating mental fatigue, as well as depression, in MS. Larger, randomized double-blind controlled trials are warranted to confirm the present preliminary observations.

Marginal zone lymphoma (MZL) is a heterogeneous B-cell malignancy for which no standard treatment exists. MZL is frequently linked to chronic infection, which may induce B-cell receptor (BCR) signaling, resulting in aberrant B-cell survival and proliferation. We conducted a multicenter, open-label, phase 2 study to evaluate the efficacy and safety of ibrutinib in previously treated MZL. Patients with histologically confirmed MZL of all subtypes who received ≥1 prior therapy with an anti-CD20 antibody-containing regimen were treated with 560 mg ibrutinib orally once daily until progression or unacceptable toxicity. The primary end point was independent review committee-assessed overall response rate (ORR) by 2007 International Working Group criteria. Among 63 enrolled patients, median age was 66 years (range, 30-92). Median number of prior systemic therapies was 2 (range, 1-9), and 63% received ≥1 prior chemoimmunotherapy. In 60 evaluable patients, ORR was 48% (95% confidence interval [CI], 35-62). With median follow-up of 19.4 months, median duration of response was not reached (95% CI, 16.7 to not estimable), and median progression-free survival was 14.2 months (95% CI, 8.3 to not estimable). Grade ≥3 adverse events (AEs; >5%) included anemia, pneumonia, and fatigue. Serious AEs of any grade occurred in 44%, with grade 3-4 pneumonia being the most common (8%). Rates of discontinuation and dose reductions due to AEs were 17% and 10%, respectively. Single-agent ibrutinib induced durable responses with a favorable benefit-risk profile in patients with previously treated MZL, confirming the role of BCR signaling in this malignancy. As the only approved therapy, ibrutinib provides a treatment option without chemotherapy for MZL. This study is registered at www.clinicaltrials.gov as #NCT01980628.

Some breast cancer survivors report cognitive difficulties greater than 1 year after chemotherapy. Acetylcholinesterase inhibitors (AChEI) may improve cognitive impairment. We conducted a randomized, placebo-controlled, pilot study to assess the feasibility of using the AChEI, donepezil, to improve subjective and objective measures of cognitive function in breast cancer survivors.. Women who received adjuvant chemotherapy 1-5 years prior with current cognitive dysfunction symptoms were randomized to 5 mg of donepezil/day vs placebo for 6 weeks and if tolerated 10 mg/day for 18 weeks for a total of 24 weeks. A battery of validated measures of attention, memory, language, visuomotor skills, processing speed, executive function, and motor dexterity and speed was administered at baseline and at 24 and 36 weeks. Subjective cognitive function, fatigue, sleep, mood, and health-related quality of life were evaluated at baseline and at 12, 24, and 36 weeks.. Sixty-two patients were enrolled, 76 % completed the study, self-reported compliance was 98 %, and toxicities were minimal. At the end of treatment, the donepezil group performed significantly better than the control group on two parameters of memory-the Hopkins Verbal Learning Test -Revised (HVLT-R) Total Recall (p = 0.033) and HVLT-R Discrimination (p = 0.036). There were no significant differences on other cognitive variables or in subjective cognitive function or quality of life.. Accrual to this feasibility trial was robust, retention was good, compliance was excellent, and toxicities were minimal.. Randomized clinical trials in breast cancer survivors to improve cognitive dysfunction are feasible. A phase III trial testing the efficacy of donepezil is warranted given these pilot results.

Alectinib--a highly selective, CNS-active, ALK inhibitor-showed promising clinical activity in crizotinib-naive and crizotinib-resistant patients with ALK-rearranged (ALK-positive) non-small-cell lung cancer (NSCLC). We aimed to assess the safety and efficacy of alectinib in patients with ALK-positive NSCLC who progressed on previous crizotinib.. We did a phase 2 study at 27 centres in the USA and Canada. We enrolled patients aged 18 years or older with stage IIIB-IV, ALK-positive NSCLC who had progressed after crizotinib. Patients were treated with oral alectinib 600 mg twice daily until progression, death, or withdrawal. The primary endpoint was the proportion of patients achieving an objective response by an independent review committee using Response Evaluation Criteria in Solid Tumors, version 1.1. Response endpoints were assessed in the response-evaluable population (ie, patients with measurable disease at baseline who received at least one dose of study drug), and efficacy and safety analyses were done in the intention-to-treat population (all enrolled patients). This study is registered with ClinicalTrials.gov, number NCT01871805. The study is ongoing and patients are still receiving treatment.. Between Sept 4, 2013, and Aug 4, 2014, 87 patients were enrolled into the study (intention-to-treat population). At the time of the primary analysis (median follow-up 4·8 months [IQR 3·3-7·1]), 33 of 69 patients with measurable disease at baseline had a confirmed partial response; thus, the proportion of patients achieving an objective response by the independent review committee was 48% (95% CI 36-60). Adverse events were predominantly grade 1 or 2, most commonly constipation (31 [36%]), fatigue (29 [33%]), myalgia 21 [24%]), and peripheral oedema 20 [23%]). The most common grade 3 and 4 adverse events were changes in laboratory values, including increased blood creatine phosphokinase (seven [8%]), increased alanine aminotransferase (five [6%]), and increased aspartate aminotransferase (four [5%]). Two patients died: one had a haemorrhage (judged related to study treatment), and one had disease progression and a history of stroke (judged unrelated to treatment).. Alectinib showed clinical activity and was well tolerated in patients with ALK-positive NSCLC who had progressed on crizotinib. Therefore, alectinib could be a suitable treatment for patients with ALK-positive disease who have progressed on crizotinib.. F Hoffmann-La Roche.

Surgery-induced acute postoperative pain and stress response can lead to prolonged convalescence. The present study was designed to investigate the effects of intraoperative dexmedetomidine on postoperative analgesia and recovery following abdominal hysterectomy surgeries. Sixty-four patients scheduled for abdominal hysterectomy under general anesthesia were divided into two groups that were maintained using propofol/remifentanil/dexmedetomidine (PRD) or propofol/remifentanil/saline (PRS). During surgery, patients in the PRD group had a lower bispectral index (BIS) value, which indicated a deeper anesthetic state, and a higher sedation score immediately after extubation than patients in the PRS group. During the first 24 hours post-surgery, PRD patients consumed less morphine with patient-controlled analgesia (PCA) and had lower scores on a visual analogue scale (VAS) than their controls from the PRS group. The global 40-item quality of recovery questionnaire and 9-question fatigue severity score both showed higher recovery scores from day 3 after surgery in the PRD group. with the data are considered together, intraoperative administration of dexmedetomidine appeared to promote the analgesic properties of morphine-based PCA and to expedite recovery following surgery in patients undergoing abdominal hysterectomy.

Chronic lymphocytic leukemia (CLL) primarily affects older persons who often have coexisting conditions in addition to disease-related immunosuppression and myelosuppression. We conducted an international, open-label, randomized phase 3 trial to compare two oral agents, ibrutinib and chlorambucil, in previously untreated older patients with CLL or small lymphocytic lymphoma.. We randomly assigned 269 previously untreated patients who were 65 years of age or older and had CLL or small lymphocytic lymphoma to receive ibrutinib or chlorambucil. The primary end point was progression-free survival as assessed by an independent review committee.. The median age of the patients was 73 years. During a median follow-up period of 18.4 months, ibrutinib resulted in significantly longer progression-free survival than did chlorambucil (median, not reached vs. 18.9 months), with a risk of progression or death that was 84% lower with ibrutinib than that with chlorambucil (hazard ratio, 0.16; P<0.001). Ibrutinib significantly prolonged overall survival; the estimated survival rate at 24 months was 98% with ibrutinib versus 85% with chlorambucil, with a relative risk of death that was 84% lower in the ibrutinib group than in the chlorambucil group (hazard ratio, 0.16; P=0.001). The overall response rate was higher with ibrutinib than with chlorambucil (86% vs. 35%, P<0.001). The rates of sustained increases from baseline values in the hemoglobin and platelet levels were higher with ibrutinib. Adverse events of any grade that occurred in at least 20% of the patients receiving ibrutinib included diarrhea, fatigue, cough, and nausea; adverse events occurring in at least 20% of those receiving chlorambucil included nausea, fatigue, neutropenia, anemia, and vomiting. In the ibrutinib group, four patients had a grade 3 hemorrhage and one had a grade 4 hemorrhage. A total of 87% of the patients in the ibrutinib group are continuing to take ibrutinib.. Ibrutinib was superior to chlorambucil in previously untreated patients with CLL or small lymphocytic lymphoma, as assessed by progression-free survival, overall survival, response rate, and improvement in hematologic variables.

In patients with chronic lymphoid leukemia (CLL) or small lymphocytic lymphoma (SLL), a short duration of response to therapy or adverse cytogenetic abnormalities are associated with a poor outcome. We evaluated the efficacy of ibrutinib, a covalent inhibitor of Bruton's tyrosine kinase, in patients at risk for a poor outcome.. In this multicenter, open-label, phase 3 study, we randomly assigned 391 patients with relapsed or refractory CLL or SLL to receive daily ibrutinib or the anti-CD20 antibody ofatumumab. The primary end point was the duration of progression-free survival, with the duration of overall survival and the overall response rate as secondary end points.. At a median follow-up of 9.4 months, ibrutinib significantly improved progression-free survival; the median duration was not reached in the ibrutinib group (with a rate of progression-free survival of 88% at 6 months), as compared with a median of 8.1 months in the ofatumumab group (hazard ratio for progression or death in the ibrutinib group, 0.22; P<0.001). Ibrutinib also significantly improved overall survival (hazard ratio for death, 0.43; P=0.005). At 12 months, the overall survival rate was 90% in the ibrutinib group and 81% in the ofatumumab group. The overall response rate was significantly higher in the ibrutinib group than in the ofatumumab group (42.6% vs. 4.1%, P<0.001). An additional 20% of ibrutinib-treated patients had a partial response with lymphocytosis. Similar effects were observed regardless of whether patients had a chromosome 17p13.1 deletion or resistance to purine analogues. The most frequent nonhematologic adverse events were diarrhea, fatigue, pyrexia, and nausea in the ibrutinib group and fatigue, infusion-related reactions, and cough in the ofatumumab group.. Ibrutinib, as compared with ofatumumab, significantly improved progression-free survival, overall survival, and response rate among patients with previously treated CLL or SLL.

Surrogates may provide easy and quick access to information about pharmacological parameters of interest that can be directly measured only with difficulty. Surrogates have been proposed for opioid blood concentrations to replace invasive sampling, serving as a basis for target-controlled infusion systems to optimize analgesia. We aimed at identifying surrogates of remifentanil steady-state blood concentrations with relevance for its clinical, in particular, analgesic, effects. A "single ascending dose" study design assessed concentration-dependent effects of remifentanil in a double-blind randomized fashion in 16 healthy volunteers. Remifentanil was administered by means of computerized infusion aimed at steady-state effect-site concentrations of 0, 1.2, 1.8, 2.4, 3, 3.6, 4.8, and 6 ng/ml (one concentration per subject, two subjects per concentration). Arterial remifentanil blood concentrations were measured during apparent steady state. Pharmacodynamic parameters were measured at baseline and during steady-state conditions. Potential surrogate parameters included the pupil diameter, the amplitude of pupil light reflex, and the performance in a visual tracking task. Clinical parameters were analgesia to experimental pain, nausea, tiredness, and visual acuity. Remifentanil blood concentrations were well predicted by its effects on the pupil light reflex amplitude, better than by its miotic effects. However, the best prediction for both remifentanil blood concentrations and analgesic effects was obtained using a combination of three surrogate parameters (pupil diameter, light reflex amplitude, and tracking performance). This combination of pharmacodynamic parameters provided even better predictions of analgesia than could be obtained using the measured opioid blood concentrations. Developing surrogates only for opioid blood concentrations is insufficient when opioid effects are the final goal. Combining pharmacodynamic surrogate parameters seems to provide a promising approach to obtain acceptable predictions of relevant clinical effects, with better results than obtained with measuring or estimating blood concentrations.

Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare, fatal, segmental premature aging syndrome caused by a mutation in LMNA that produces the farnesylated aberrant lamin A protein, progerin. This multisystem disorder causes failure to thrive and accelerated atherosclerosis leading to early death. Farnesyltransferase inhibitors have ameliorated disease phenotypes in preclinical studies. Twenty-five patients with HGPS received the farnesyltransferase inhibitor lonafarnib for a minimum of 2 y. Primary outcome success was predefined as a 50% increase over pretherapy in estimated annual rate of weight gain, or change from pretherapy weight loss to statistically significant on-study weight gain. Nine patients experienced a ≥50% increase, six experienced a ≥50% decrease, and 10 remained stable with respect to rate of weight gain. Secondary outcomes included decreases in arterial pulse wave velocity and carotid artery echodensity and increases in skeletal rigidity and sensorineural hearing within patient subgroups. All patients improved in one or more of these outcomes. Results from this clinical treatment trial for children with HGPS provide preliminary evidence that lonafarnib may improve vascular stiffness, bone structure, and audiological status.

Early recovery of patients following sedation/analgesia and anesthesia is important in ambulatory practice. The aim of this study was to assess whether modafinil, used for the treatment of narcolepsy, improves recovery following sedation/analgesia.. Patients scheduled for extracorporeal shock wave lithotripsy were randomly assigned to one of four groups. Two groups received a combination of fentanyl/midazolam with either modafinil or placebo. The remaining groups received remifentanil/propofol with either modafinil or placebo. Modafinil 200 mg was administered to the treatment group patients 1 h before sedation/analgesia. Groups were compared using the digital symbol substitution test (DSST), trail making test (TMT), observer scale of sedation and analgesia (OAA/S) and Aldrete score. Verbal rating scale (VRS) scores for secondary outcome variables e.g. energy, tiredness and dizziness were also recorded before and after treatment.. Sixty-seven patients successfully completed the study. Groups received similar doses of sedation and analgesic drugs. No statistically significant difference was found for DSST between groups. No significant adverse effects occurred in relation to modafinil. No statistically significant difference between groups was identified for TMT, OAA/S and Aldrete scores. The mean VRS score for tiredness was lesser in the modafinil/fentanyl/midazolam group [1.3 (2.0)] compared with the placebo group [3.8 (2.5)], P=0.02. Such a difference was not found between the remifentanil/propofol groups [placebo 2.6 (2.2) vs. modafinil 3.1(2.7)], p>0.05. Dizziness was greater in the modafinil/remifentanil/propofol group 1.7 (2.0) vs. placebo 0.0 (0.5), p<0.05.. Modafinil reduces patient-reported tiredness after sedation/analgesia but does not improve recovery in terms of objective measures of patient psychomotor skills.

Depletion of cellular nicotinamide adenine dinucleotide (NAD) by inhibition of its synthesis is a new pharmacological principle for cancer treatment currently in early phases of clinical development. We present new and previously published data on the safety and efficacy of these drugs based on early clinical trials.. A phase I clinical trial of CHS 828 in patients with advanced solid tumours was performed. Published clinical trials on NAD depleting drugs for cancer treatment were summarised for safety and efficacy.. Seven patients with previously treated solid tumours received oral administration of CHS 828 in the dose range 20-80 mg once weekly for 3 weeks in 4 weeks cycles. Toxicity was dominated by gastrointestinal symptoms including nausea, vomiting, diarrhoea, constipation, subileus and gastric ulcer. One patient had thrombocytopenia grade 2. There were two cases each of grade 3-4 hyperuricemia and hypokalemia. Safety and efficacy of the NAD depleting drugs CHS 828 and FK866 have been reported from four phase I clinical trials, including a total of 97 patients with previously treated solid tumours. Outstanding toxicity reported was thrombocytopenia and various gastrointestinal symptoms. No objective tumour remission has been observed in the total of 104 patients treated in the above early trials.. Critical toxicity from NAD depleting cancer drugs to consider in future trials seems to be thrombocytopenia and various gastrointestinal symptoms. Efficacy of NAD depleting drugs when used alone is expected to be low.

Gabapentin is an anticonvulsant drug that has analgesic properties for acute postoperative pain. However, the analgesic effect of gabapentin as an antiepileptic prophylactic drug on patients undergoing craniotomy is unclear. In this study, we evaluated the postoperative effectiveness of gabapentin on acute postoperative pain when it is used for antiepileptic prophylaxis in patients undergoing craniotomy for supratentorial tumor resection.. Eighty patients undergoing craniotomy for supratentorial tumor resection were randomly assigned into two groups. Patients in Group G (n = 40) received oral gabapentin (3 x 400 mg), and patients in Group P (n = 40) received oral phenytoin (3 x 100 mg) for 7 days before the operation and postoperatively. An identical anesthesia protocol was performed for both the groups. Anesthesia was maintained with propofol and remifentanil infusion. Patient-controlled analgesia with morphine was used, and pain levels were measured. The antiepileptic-related side effects, anesthetic consumption, duration of anesthesia and surgery, tracheal extubation time, postoperative pain scores, morphine consumption, and sedation scores were recorded.. Thirty-seven patients in Group G and 38 patients in Group P completed the study. During the preoperative period in Group G, one patient had severe fatigue, one had severe dizziness, and one patient's surgical procedure was changed. The median plasma levels of gabapentin were 34 micromol/mL (range, 23-51 micromol/mL) in 34 patients. In Group P, one patient withdrew from the study preoperatively and one developed transient neurological symptoms postoperatively. The demographic data and mean duration of anesthesia and surgery were similar in both the groups. The total propofol and remifentanil consumption in Group G (1847 +/- 548 mg/3034 +/- 1334 microg) was significantly less than that of Group P (2293 +/- 580 mg/4287 +/- 1282 microg) (P = 0.01). However, tracheal extubation could be done earlier in Group P (4.5 +/- 2 min) than in Group G (16.6 +/- 22 min) (P < 0.001). Pain scores were significantly higher in Group P at 15 min, 30 min, and 1 h (P < 0.001). The total morphine consumption was also significantly higher in Group P (33 +/- 17 mg vs 24 +/- 19 mg) (P = 0.01). The postoperative sedation scores were significantly higher in Group G at 15 min, 30 min, 1 h, and 2 h (P < 0.001).. The administration of gabapentin to patients undergoing craniotomy for supratentorial tumor resection was effective for acute postoperative pain. It also decreased analgesic consumption after surgery. However, it may lead to side effects such as delayed tracheal extubation and increased sedation postoperatively.

FK866 is a potent inhibitor or NAD synthesis. This first-in-human study was performed to determine the maximum-tolerated dose, toxicity profile, and pharmacokinetics on a 96-h continuous infusion schedule.. Twenty four patients with advanced solid tumor malignancies refractory to standard therapies were treated with escalating doses of FK866 as a continuous, 96-h infusion given every 28 days. Serial plasma samples were collected to characterize the pharmacokinetics of FK866. Further blood samples were collected for the measurement of plasma VEGF levels.. There were 12 women and 12 men with a median age of 61 (range 34-78) and a median KPS of 80%, received a 4-day of infusion of FK866 at dose levels of 0.018 mg/m2/h (n=3), 0.036 mg/m2/h (n=3), 0.072 mg/m2/h (n=3), 0.108 mg/m2/h (n=4), 0.126 mg/m2/h (n=6), and 0.144 mg/m2/h (n=5). Thrombocytopenia was the dose limiting toxicity, observed in two patients at the highest dose level and one patient at the recommended phase II dose of 0.126 mg/m2/h No other hematologic toxicities were noted other than mild lymphopenia and anemia. There was mild fatigue and grade 3 nausea; the latter was controlled with antiemetics and was not a DLT. Css (the mean of the 72 and 96 h plasma concentrations) increased in relation to the dose escalation. The study drug did not significantly affect plasma concentrations of VEGF. There were no objective responses, although four patients had stable disease (on treatment for 3 months or greater).. The recommended phase II dose is 0.126 mg/m2/h given as a continuous 96-h infusion every 28 days. The dose limiting toxicity of FK866 is thrombocytopenia. Pharmacokinetic data suggest an increase in the plasma Css in relation to the escalation of FK866.

This phase I study was conducted to evaluate the safety, tolerability, pharmacological properties and biological activity of the combination of the lonafarnib, a farnesylproteintransferase (FTPase) inhibitor, with gemcitabine and cisplatin in patients with advanced solid malignancies.. This was a single institution study to determine the maximal tolerated dose (MTD) of escalating lonafarnib (75-125 mg po BID) with gemcitabine (750-1,000 mg/m(2) on days 1, 8, 15) and fixed cisplatin (75 mg/m(2) day 1) every 28 days. Due to dose-limiting toxicities (DLTs) of neutropenia and thrombocytopenia in initial patients, these patients were considered "heavily pre-treated" and the protocol was amended to limit prior therapy and re-escalate lonafarnib in "less heavily pre-treated patients" on 28-day and 21-day schedules. Cycle 1 and 2 pharmacokinetics (PK), and farnesylation of the HDJ2 chaperone protein and FPTase activity were analyzed.. Twenty-two patients received 53 courses of therapy. Nausea, vomiting, and fatigue were frequent in all patients. Severe toxicities were observed in 91% of patients: neutropenia (41%), nausea (36%), thrombocytopenia (32%), anemia (23%) and vomiting (23%). Nine patients withdrew from the study due to toxicity. DLTs of neutropenia, febrile neutropenia, thrombocytopenia, and fatigue limited dose-escalation on the 28-day schedule. The MTD was established as lonafarnib 75 mg BID, gemcitabine 750 mg/m(2) days 1, 8, 15, and cisplatin 75 mg/m(2) in heavily pre-treated patients. The MTD in the less heavily pre-treated patients could not be established on the 28-day schedule as DLTs were observed at the lowest dose level, and dose escalation was not completed on the 21-day schedule due to early study termination by the Sponsor. No PK interactions were observed. FTPase inhibition was not observed at the MTD, however HDJ-2 gel shift was observed in one patient at the 100 mg BID lonafarnib dose. Anti-cancer activity was observed: four patients had stable disease lasting >2 cycles, one subject had a complete response, and another had a partial response, both with metastatic breast cancer.. Lonafarnib 75 mg BID, gemcitabine 750 mg/m(2) days 1, 8, 15, and cisplatin 75 mg/m(2) day 1 on a 28-day schedule was established as the MTD. Lonafarnib did not demonstrate FTPase inhibition at these doses. Despite the observed efficacy, substantial toxicity and questionable contribution of anti-tumor activity of lonafarnib to gemcitabine and cisplatin limits further exploration of this combination.

Lonafarnib is an orally bioavailable nonpetidomimetic farnesyl transferase inhibitor with significant activity against BCR-ABL-positive cell lines and primary human chronic myeloid leukemia (CML) cells. Lonafarnib can inhibit the proliferation of imatinib-resistant cells and increases imatinib-induced apoptosis in vitro in cells from imatinib-resistant patients.. The authors conducted a phase 1 study of lonafarnib in combination with imatinib in patients with CML who failed imatinib therapy. The starting dose level for patients with chronic phase (CP) disease was imatinib, 400 mg/day, plus lonafarnib at a dose of 100 mg twice daily. The starting dose levels for accelerated phase (AP) and blast phase (BP) disease were 600 mg/day and 100 mg twice daily, respectively.. A total of 23 patients were treated (9 with CP, 11 with AP, and 3 with BP) for a median of 25 weeks (range, 4-102 weeks). Of those with CP disease, 2 patients had grade 3 (according to the National Cancer Institute Common Toxicity Criteria [version 2.0]) dose-limiting toxicities (DLTs) at the 400 + 125-mg dose, including diarrhea (2 patients), vomiting (1 patient), and fatigue (1 patient). In patients with AP/BP disease, DLTs were observed at the 600 + 125-mg dose and was comprised of diarrhea (1 patient) and hypokalemia (1 patient). Eight patients (35%) responded; 3 with CP disease achieved a complete hematologic response (CHR) (2 patients) and a complete cytogenetic response (1 patient). Three patients with AP disease responded (2 CHR, 1 partial cytogenetic response), and 2 patients with BP disease demonstrated hematologic improvement. Pharmacokinetics data suggest no apparent increase in exposure or changes in the pharmacokinetics of either lonafarnib or imatinib when they are coadministered.. The results of the current study indicate that the combination of lonafarnib and imatinib is well tolerated and the maximum tolerated dose of lonafarnib is 100 mg twice daily when combined with imatinib at a dose of either 400 mg or 600 mg daily.

To evaluate the effectiveness of donepezil compared with placebo in cancer patients with fatigue as measured by the Functional Assessment for Chronic Illness Therapy-Fatigue (FACIT-F).. Patients with fatigue score >or= 4 on a scale of 0 to 10 (0 = no fatigue, 10 = worst possible fatigue) for more than 1 week were included. Patients were randomly assigned to receive donepezil 5 mg or placebo orally every morning for 7 days. A research nurse contacted the patients by telephone daily to assess toxicity and fatigue level. All patients were offered open-label donepezil during the second week. FACIT-F and/or the Edmonton Symptom Assessment System (ESAS) were assessed at baseline, and days 8, 11, and 15. The FACIT-F fatigue subscale score on day 8 was considered the primary end point.. Of 142 patients randomly assigned to treatment, 47 patients in the donepezil group and 56 in the placebo group were assessable for final analysis. Fatigue intensity improved significantly on day 8 in both donepezil and placebo groups. However, there was no significant difference in fatigue improvement by FACIT-F (P = .57) or ESAS (P = .18) between groups. In the open-label phase, fatigue intensity continued to be low as compared with baseline. No significant toxicities were observed.. Donepezil was not significantly superior to placebo in the treatment of cancer-related fatigue.

A prospective, open-label phase II study was conducted to determine whether donepezil, a US Food and Drug Administration-approved reversible acetylcholinesterase inhibitor used to treat mild to moderate Alzheimer's type dementia, improved cognitive functioning, mood, and quality of life (QOL) in irradiated brain tumor patients.. Thirty-four patients received donepezil 5 mg/d for 6 weeks, then 10 mg/d for 18 weeks, followed by a washout period of 6 weeks off drug. Outcomes were assessed at baseline, 12, 24 (end of treatment), and 30 weeks (end of wash-out). All tests were administered by a trained research nurse.. Of 35 patients who initiated the study, 24 patients (mean age, 45 years) remained on study for 24 weeks and completed all outcome assessments. All 24 patients had a primary brain tumor, mostly low-grade glioma. Scores significantly improved between baseline (pretreatment) and week 24 on measures of attention/concentration, verbal memory, and figural memory and a trend for verbal fluency (all P < .05). Confused mood also improved from baseline to 24 weeks (P = .004), with a trend for fatigue and anger (all P < .05). Health-related QOL improved significantly from baseline to 24 weeks, particularly, for brain specific concerns with a trend for improvement in emotional and social functioning (all P < .05).. Cognitive functioning, mood, and health-related QOL were significantly improved following a 24-week course of the acetylcholinesterase inhibitor donepezil. Toxicities were minimal. We are planning a double blinded, placebo-controlled, phase III trial of donepezil to confirm these favorable results.

Halofuginone (tempostatin) is a synthetic derivative of a quinazolinone alkaloid showing anti-angiogenic, anti-metastatic and anti-proliferative effects in preclinical studies. The objectives of this phase I study were to assess the dose-limiting toxicities (DLTs), to determine the maximum tolerated dose (MTD) and to study the pharmacokinetics (PKs) of halofuginone when administered once or twice daily orally to patients with advanced solid tumours.. Patients were treated with escalating doses of halofuginone at doses ranging from 0.5 to 3.5 mg/day. For pharmacokinetic analysis plasma sampling was performed during the first and second course and assayed using a validated high-performance liquid chromatographic assay with mass spectrometric detection.. Twenty-four patients received a total of 106 courses. The 'acute' MTD was reached at 3.5 mg/day, with nausea, vomiting, and fatigue as DLT. The recommended dose for chronic administration was defined as 0.5mg/day with the requirement of 5HT3 antagonists to control nausea and vomiting considered as DLT. Several patients experienced bleeding complications on treatment with halofuginone in which a causal relationship could not be excluded. The PKs of halofuginone were linear over the dose range studied with a large interpatient variability.. In this study the DLT of halofuginone was nausea, vomiting, and fatigue. The recommended dose for phase II studies of halofuginone is 0.5mg administered orally, once daily.

To test the activity of the cyclin dependent kinase (cdk) inhibitor flavopiridol in malignant melanoma, a disease with frequent abnormalities of the cyclin dependent kinase system.. Patients had histologically proven, unidimensionally measurable malignant melanoma, incurable by standard therapy. Prior adjuvant immunotherapy was allowed, but patients were otherwise untreated for advanced disease. Flavopiridol was administered at a dose of 50 mg/m(2) IV over 1 hour daily x 3 days every 3 weeks. Patients were assessed for response every 2 cycles.. 17 patients were accrued over 5 months. No objective responses were documented in the 16 patients evaluable for response. Seven patients (44%) had stable disease after 2 cycles, with a median of 2.8 months (range 1.8-9.2). The most common treatment-related non-hematologic toxicities were diarrhea (82%), nausea (47%), fatigue (41%), anorexia (35%) and vomiting (29%). Most treatment-related toxicities were mild, except for diarrhea (grade 3 in 3 patients, grade 4 in 1 patient), nausea (grade 3 in 1 patient) and tumor pain (grade 3 in 1 patient). Hematologic toxicities were minimal, none worse than grade 2. Eighty-eight percent of patients received >/=90% planned dose intensity; 2 patients had dose reductions for gastrointestinal (GI) toxicity.. Flavopiridol is well tolerated at the dose regimen used in this study, with an acceptable (primarily GI) toxicity profile. Although 7 of the 16 patients had stable disease ranging from 1.8 to 9.2 months in duration, there was no evidence of significant clinical activity in malignant melanoma by objective response criteria.

To establish the maximum tolerated dose of lonafarnib, a novel farnesyltransferase inhibitor, in combination with paclitaxel in patients with solid tumors and to characterize the safety, tolerability, dose-limiting toxicity, and pharmacokinetics of this combination regimen.. In a Phase I trial, lonafarnib was administered p.o., twice daily (b.i.d.) on continuously scheduled doses of 100 mg, 125 mg, and 150 mg in combination with i.v. paclitaxel at doses of 135 mg/m(2) or 175 mg/m(2) administered over 3 h on day 8 of every 21-day cycle. Plasma paclitaxel and lonafarnib concentrations were collected at selected time points from each patient.. Twenty-four patients were enrolled; 21 patients were evaluable. The principal grade 3/4 toxicity was diarrhea (5 of 21 patients), which was most likely due to lonafarnib. dose-limiting toxicities included grade 3 hyperbilirubinemia at dose level 3 (100 mg b.i.d. lonafarnib and 175 mg/m(2) paclitaxel); grade 4 diarrhea and grade 3 peripheral neuropathy at dose level 3A (125 mg b.i.d. lonafarnib and 175 mg/m(2) paclitaxel); and grade 4 neutropenia with fever and grade 4 diarrhea at level 4 (150 mg b.i.d. lonafarnib and 175 mg/m(2) paclitaxel). The maximum tolerated dose established by the continual reassessment method was lonafarnib 100 mg b.i.d. and paclitaxel 175 mg/m(2). Paclitaxel appeared to have no effect on the pharmacokinetics of lonafarnib. The median duration of therapy was eight cycles, including seven cycles with paclitaxel. Six of 15 previously treated patients had a durable partial response, including 3 patients who had previous taxane therapy. Notably, two of five patients with taxane-resistant metastatic non-small cell lung cancer had partial responses.. When combined with paclitaxel, the recommended dose of lonafarnib for Phase II trials is 100 mg p.o. twice daily with 175 mg/m(2) of paclitaxel i.v. every 3 weeks. Additional studies of lonafarnib in combination regimens appear warranted, particularly in patients with non-small cell lung cancer.

To determine the response rate and toxicity of flavopiridol in patients with previously untreated or relapsed mantle-cell lymphoma.. Adult patients with previously untreated or in first or second relapse of previously responsive mantle-cell lymphoma were given flavopiridol 50 mg/m2/d by intravenous bolus for 3 consecutive days every 21 days with antidiarrheal prophylaxis. Flavopiridol was continued until disease progression, unacceptable toxicity, or stable disease for four cycles. Disease was reassessed every two cycles.. From 33 registered patients, 30 were eligible after pathology review, 30 were assessable for toxicity, and 28 were assessable for response. A median of four cycles of treatment was administered; 90% of patients received at least 90% of planned dose-intensity. No complete responses were seen; three patients had a partial response (11%), 20 patients had stable disease (71%), and five patients had progressive disease (18%). The median duration of response was 3.3 months (range, 2.8 to 13.2 months). The most common toxicities were diarrhea (97%), fatigue (73%), nausea (47%), and vomiting (27%). At least one nonhematologic grade 3 or 4 toxicity was seen in 14 patients (47%). Hematologic toxicity was modest.. Flavopiridol given as a daily bolus for 3 consecutive days every 3 weeks has modest activity as a single agent for mantle-cell lymphoma. The number of stable and partial responses that was seen indicates that it is biologically active and may delay progression. Future studies in mantle-cell lymphoma should test this agent with other active agents and using different schedules.

Flavopiridol is the first cyclin-dependent kinase inhibitor to enter clinical trials. Activity in gastric cancer xenografts and in a patient with gastric cancer on the phase I trial led to this phase II study of flavopiridol in patients with metastatic gastric cancer.. Sixteen patients were entered onto the study, and 14 were assessable for response. Flavopiridol was administered initially at a dose of 50 mg/m(2)/d by continuous infusion for 72 hours every 2 weeks. Assessment of plasma pharmacokinetics was performed in all patients. Peripheral mononuclear cells were collected throughout the 72-hour infusion for determinants of apoptosis.. There were no major objective responses (exact confidence interval 0% to 23%). One patient achieved a minor response in his liver metastases, though the primary progressed. Other patients exhibited histologic and radiographic evidence of tumor necrosis. Common toxicities included fatigue in 93% of patients (grade 3 or 4 in 27%) and diarrhea in 73% of patients (grade 3 or 4 in 20%). Five patients (33%) developed venous thromboses at the central catheter tip. The studies performed on peripheral mononuclear cells indicated no induction of apoptosis.. Flavopiridol administered as a single agent for 72 hours every 14 days is inactive in the treatment of gastric cancer. The drug also induced an unexpected higher incidence of vascular thrombosis and fatigue than was anticipated from the phase I trials. Future development of flavopiridol will depend on other doses and schedules in combination with chemotherapy.

The objective of this study was to describe real-world health-related quality of life (HRQoL) and treatment satisfaction of ibrutinib-treated patients with CLL compared to a reference group. This study was completed in two parts. The first portion (Norming Study) was a US online survey conducted to serve as a reference population. The Norming Study included a total of 139 patients with CLL, excluding those treated with ibrutinib: 64 were treatment naive (Tx naive), 36 were 1st line (1L), and 38 were in or had completed ≥2 lines (2L+) patients with CLL. The second portion (CLL Ibrutinib Study) included 1L and 2L+ ibrutinib patients with CLL treated for ≥6 months in which 118 patients (1L n = 88 and 2L+ n = 30) completed the study. Respondents completed demographic and clinical information and the following HRQoL surveys: (Short Form-12v2® Health Survey [SF-12v2], Functional Assessment of Cancer Therapy-General [FACT-G], FACT-Leukemia [FACT-Leu] Functional Assessment of Chronic Illness Therapy [FACIT]-Fatigue, and Cancer Therapy Satisfaction Questionnaire [CTSQ]). Higher scores indicate better HRQoL/treatment satisfaction. Differences in effect sizes between the two samples at the group level were calculated using Hedges' g. Medium to large positive effects were seen in the CLL Ibrutinib group on several measures compared to the Reference Study groups. The FACT-G total score was 89.2±11.1 for CLL Ibrutinib Study patients compared to 75.8±22.6 CLL Norming Tx naïve patients, 61.3±21.8 in 1L, and 61.7±20.7 in 2L+. Similar trends were seen with FACT-Leu total score and FACIT-Fatigue. CLL Ibrutinib Study patients scored higher on all CTSQ domain scores compared to the CLL Norming patients treated with other CLL therapies. We found that Ibrutinib-treatment had better HRQoL and treatment satisfaction compared to patients receiving other therapies, irrespective of line of therapy.

Two tyrosine kinase inhibitors (TKIs), lenvatinib and vandetanib, are often used to treat advanced radioiodine-refractory differentiated thyroid cancer (RAI-R DTC) and medullary thyroid cancer (MTC), respectively. Fatigue is a common adverse event during treatment with these and other TKIs and a common cause of drug discontinuation or dosage reduction.. We evaluated the basal and stimulated adrenal function in 12 patients with advanced RAI-R DTC and MTC treated with lenvatinib or vandetanib, respectively. Ten patients complaining of fatigue showed a progressive ACTH increase with normal cortisol levels. Moreover, six of 10 patients had a blunted cortisol response after ACTH stimulation, thus confirming the diagnosis of primary adrenal insufficiency (PAI). The causal relationship between TKIs and PAI onset was also demonstrated by the repeated testing of adrenal function before and during treatment. Patients with PAI received cortisone acetate replacement therapy, with a substantial and prompt improvement in the degree of fatigue, as assessed by the Common Terminology Criteria for Adverse Events version 4.03, thus supporting the major impact of impaired adrenal function in the genesis of this adverse event.. We show that the occurrence of PAI may be a common cause of fatigue during lenvatinib and vandetanib treatment, and we therefore recommend testing adrenal function for a prompt start of replacement therapy to avoid treatment discontinuation, dosage reduction, and potentially severe PAI complications.

Poly(ADP-ribose) polymerase (PARP) proteins are used by cells in several DNA repair processes. PARP inhibition can result in preferential death of cancer cells when another mechanism for repairing DNA is defective. Two PARP inhibitors, olaparib and rucaparib, have been approved by the US Food and Drug Administration (FDA) for the treatment of recurrent, BRCA-associated ovarian cancer. More recently, these two and a third PARP inhibitor, niraparib, were approved by the FDA as maintenance therapy following platinum-based chemotherapy for recurrent ovarian cancer. This has caused a paradigm shift in disease management and a challenge for clinicians, who must decide how best to use these agents in individualized treatment. The oral formulation is attractive to patients, but adverse effects such as nausea and fatigue can impact quality of life. As clinicians become comfortable selecting PARP inhibitors and managing associated toxicities, future steps will be to investigate how to safely administer them in combination with other therapies.

Tofacitinib is an oral Janus kinase inhibitor for the treatment of RA. The aim of this analysis was to characterize changes in haematological parameters following tofacitinib treatment, and to compare changes in haemoglobin with markers of disease activity, fatigue and vitality.. Changes in neutrophil counts, lymphocyte counts and haemoglobin levels were analysed in patients with RA from six phase 3 randomized controlled trials (n = 4271) of tofacitinib 5 or 10 mg bd, placebo or active comparators of up to 24 months' duration, and two long-term extension (LTE) studies (n = 4858) of tofacitinib of up to 84 months' duration. Disease activity markers included CRP and ESR. Fatigue and vitality were assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) and Short Form Health Survey-36 vitality domain scores.. In phase 3 studies, mean neutrophil and lymphocyte counts decreased and mean haemoglobin levels increased in all tofacitinib treatment groups. Haemoglobin levels and neutrophil counts stabilized in the LTE studies, while lymphocyte count decreases stabilized at approximately month 48. Increased haemoglobin was associated with decreased ESR and CRP levels. Clinically meaningful reductions in haemoglobin levels (⩾3 g/dl from baseline or haemoglobin ⩽7 g/dl) occurred in <1.0% of patients in all treatment groups. FACIT-F and Short Form Health Survey-36 vitality scores were weakly correlated with haemoglobin levels.. Small changes in haematological parameters were seen with tofacitinib treatment, which stabilized over time in the LTE studies. Changes in haemoglobin levels, although associated with changes in ESR and CRP, were not associated with fatigue or vitality.

Ibrutinib is an orally administered inhibitor of Bruton tyrosine kinase that antagonizes B-cell receptor, chemokine, and integrin-mediated signaling. In early-phase studies, ibrutinib demonstrated high response rates and prolonged progression-free survival (PFS) in chronic lymphocytic leukemia (CLL). The durable responses observed with ibrutinib relate in part to a modest toxicity profile that allows the majority of patients to receive continuous therapy for an extended period. We report on median 3-year follow-up of 132 patients with symptomatic treatment-naïve and relapsed/refractory CLL or small lymphocytic lymphoma. Longer treatment with ibrutinib was associated with improvement in response quality over time and durable remissions. Toxicity with longer follow-up diminished with respect to occurrence of grade 3 or greater cytopenias, fatigue, and infections. Progression remains uncommon, occurring primarily in some patients with relapsed del(17)(p13.1) and/or del(11)(q22.3) disease. Treatment-related lymphocytosis remains largely asymptomatic even when persisting >1 year and does not appear to alter longer-term PFS and overall survival compared with patients with partial response or better. Collectively, these data provide evidence that ibrutinib controls CLL disease manifestations and is well tolerated for an extended period; this information can help direct potential treatment options for different subgroups to diminish the long-term risk of relapse.

The current study was designed to investigate the effects of 1-(1,3-benzodioxol-5-yl-carbonyl) piperidine (1-BCP) on swimming endurance capacity which as one indicator of fatigue in the weight-loaded forced swimming mice. Mice were given either vehicle or 1-BCP (0.1, or 0.2 mmol/kg body weight daily) by intraperitoneal injection once daily for 2 weeks. The 1-BCP groups showed a significant increase in swimming time to exhaustion compared with the control group. 1-BCP increased the liver glycogen (LG) and muscle glycogen (MG) contents significantly, while decreased the lactic acid (LA) and blood urea nitrogen (BUN) levels notably compared with control group. Besides, 1-BCP treatment also significantly improved the endogenous cellular antioxidant enzymes in mice by increasing the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px). Therefore, this study demonstrated for the first time that the supplementation of 1-BCP, as a positive allosteric modulator of α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor, could enhance the endurance capacity of mice and facilitated them recovery from fatigue. Thus, we provide a new effective therapeutic strategy for fatigue.

Blonanserin is a novel atypical antipsychotic drug acting as a mixed serotonin 5-HT2A and dopamine D2 receptor antagonist. This study investigated the pharmacokinetics and safety of blonanserin in healthy Chinese males.. This was an open-label trial with two parts. Twenty-four subjects were enrolled in part A to receive a single fasting dose of 4 or 8 mg blonanserin (each n = 12); part B recruited 12 subjects and administered single and sequentially twice-daily multiple postprandial doses of blonanserin 2 mg for 9 days. Serial blood samples were taken for the bioassay of plasma blonanserin and its four metabolites during both sub-studies. Safety was assessed, including repeat measurements of fasting serum prolactin, insulin, triglyceride and cholesterol.. Blonanserin was rapidly absorbed, accompanied with immediate plasma concentration elevation of the N-oxide form (M2) and gradual rises of the N-deethylated form (M1) and its downstream metabolites. The mean elimination half-life of blonanserin (7.7-11.9 h) was much longer than that of M2 (1.2-1.3 h) but shorter than that of M1 (26.4-31.4 h) after single fasting doses. After food intake, a single dose of 2 mg blonanserin resulted in total exposure and peak concentrations of blonanserin similar to those observed with a single fasting dose of blonanserin 4 mg. Moreover, the relationship of metabolite over parent compound ratio was different between M1 and M2 after single and multiple postprandial administrations (single dose vs multiple dose: M1, 0.33 vs 0.75; M2, 0.13 vs 0.067). Mild but transient increases of prolactin, insulin and triglyceride were observed.. The pharmacokinetics of blonanserin in Chinese subjects were similar to those observed in Japanese subjects. This study suggested that food intake not only increases the bioavailability of blonanserin but differently affects the pharmacokinetics of its metabolites as well. The drug was safe and well tolerated in healthy Chinese males.

To explore novel antifatigue agents targeting with AMPA receptor, 10 compounds were synthesized and their structures were confirmed by 1H NMR, ESI-MS and elemental analysis. 1-BCP was treated as the leading compound. The antifatigue activities were evaluated by weight-loaded forced swimming test, and the AMPA receptor binding affinities were tested with radioligand receptor binding assays. The results unveiled that 5b appeared to possess potent antifatigue activities and high affinity with AMPA receptor, which deserved further studies.

Multiple sclerosis (MS) is the leading cause of neurological disability among young and middle-aged adults. One of the most devastating consequences of MS in this relatively young population group is unemployment. Although certain demographic and disease factors have been associated with employment, few studies have examined the contribution of person-specific factors, such as personality.. The goal of this study was to determine the extent to which personality, demographics, and clinical measures contribute to unemployment in MS.. A total of 101 individuals with MS who were enrolled in a clinical trial on cognition underwent a brief neuropsychological battery and completed questionnaires related to vocation, mood, fatigue, and personality. Neurological impairment was measured with the Expanded Disability Status Scale (EDSS).. Employment status was related with disease duration, MS subtype, level of neurological impairment, fatigue, performance on measures assessing information processing speed (Symbol Digit Modalities Test (SDMT)), learning and memory (Selective Reminding Test), and the personality characteristic of persistence. Based on a forward logistic regression analysis, EDSS, SDMT, and persistence were the strongest predictors of employment status.. These findings underscore the importance of personality on outcomes in MS and point to the need for more clinical attention and research in this area.
