Sustainable and equivalent improvements in symptoms and functional well-being following viral cure from ledipasvir/sofosbuvir versus elbasvir/grazoprevir for chronic hepatitis C infection: Findings from the randomized PRIORITIZE trial.
The PRIORITIZE trial (clinicaltrials.gov: NCT02786537) was the first comparative effectiveness study to directly compare ledipasvir/sofosbuvir (LDV/SOF) and elbasvir/grazoprevir (EBR/GZR) for the treatment of chronic hepatitis C virus (HCV). A secondary aim of this study was to compare LDV/SOF and EBR/GZR on sustainable changes in several HCV-associated symptoms and functional well-being in patients who achieved sustained virological response (SVR). PRIORITIZE, a randomized controlled trial conducted between 2016 and 2020, evaluated change in six PROMIS® symptom scores (fatigue, sleep disturbance, cognitive disturbance, nausea, diarrhoea, abdominal pain) and functional well-being using the disease-specific HCV-PRO instrument. Survey assessments were administered at baseline, early post-treatment (median = 6 months) and late post-treatment (median = 21 months). Constrained longitudinal linear mixed-effects models were used to evaluate within-treatment change and between-treatment differences. Data from 793 participants (average 55 years old, 57% male, 44% black, 17% with cirrhosis) were analysed. From baseline to early post-treatment, 5 out of 6 symptoms and functional well-being significantly improved (all p's < .05). In the LDV/SOF arm, mean changes ranged from -3.73 for nausea to -6.41 for fatigue and in the EBR/GZR, mean changes ranged from -2.19 for cognitive impairment to -4.67 for fatigue. Change of >3 points was consider clinically meaningful. Improvements in most symptoms slightly favoured LDV/SOF, although the magnitude of differences between the regimens were small. Both regimens demonstrated significant improvements in symptoms and functional well-being that were sustained during the late post-treatment phase. EBR/GZR and LDV/SOF regimens had clinically equivalent and durable improvements in HCV symptoms and functional well-being up to two years after SVR.

A randomized, double-blind, placebo-controlled, phase 3 trial to evaluate the efficacy, safety, and tolerability of prucalopride in men with chronic constipation.
Prucalopride is effective at alleviating symptoms of chronic constipation in women. The aim of this study was to assess the efficacy of 12 weeks of prucalopride treatment compared with placebo in men with chronic constipation.. This was a multicenter, stratified, randomized, parallel-group, double-blind, placebo-controlled, phase 3 study (ClinicalTrials.gov identifier: NCT01147926). The primary end point was the proportion of patients with a mean of three or more spontaneous complete bowel movements (SCBMs) per week across the treatment period. Efficacy end points were assessed using daily electronic diaries, global assessment of the severity of constipation and efficacy of treatment, and Patient Assessment of Constipation-Symptoms (PAC-SYM) and Patient Assessment of Constipation-Quality of Life (PAC-QOL) questionnaires.. In total, 374 patients were enrolled in the study. Significantly more patients achieved a mean of three or more SCBMs per week in the prucalopride group (37.9%) than in the placebo group (17.7%, P<0.0001). The proportion of patients rating their constipation treatment as "quite a bit" to "extremely" effective at the final on-treatment visit was 46.7 and 30.4% in the prucalopride and placebo groups, respectively. The difference between treatment groups was statistically significant (P<0.0001). The proportion of patients with an improvement of at least 1 point in PAC-QOL satisfaction subscale score was 52.7 and 38.8% in the prucalopride and placebo groups, respectively (P=0.0035). Prucalopride had a good safety profile and was well tolerated.. Prucalopride is effective, has a good safety profile, and is well tolerated for the treatment of men with chronic constipation.

Grazoprevir-Elbasvir Combination Therapy for Treatment-Naive Cirrhotic and Noncirrhotic Patients With Chronic Hepatitis C Virus Genotype 1, 4, or 6 Infection: A Randomized Trial.
Novel interferon- and ribavirin-free regimens are needed to treat hepatitis C virus (HCV) infection.. To evaluate the safety and efficacy of grazoprevir (NS3/4A protease inhibitor) and elbasvir (NS5A inhibitor) in treatment-naive patients.. Randomized, blinded, placebo-controlled trial. (ClinicalTrials.gov: NCT02105467).. 60 centers in the United States, Europe, Australia, Scandinavia, and Asia.. Cirrhotic and noncirrhotic treatment-naive adults with genotype 1, 4, or 6 infection.. Oral, once-daily, fixed-dose grazoprevir 100 mg/elbasvir 50 mg for 12 weeks, stratified by fibrosis and genotype. Patients were randomly assigned 3:1 to immediate or deferred therapy.. Proportion of patients in the immediate-treatment group achieving unquantifiable HCV RNA 12 weeks after treatment (SVR12); adverse events in both groups.. Among 421 participants, 194 (46%) were women, 157 (37%) were nonwhite, 382 (91%) had genotype 1 infection, and 92 (22%) had cirrhosis. Of 316 patients receiving immediate treatment, 299 of 316 (95% [95% CI, 92% to 97%]) achieved SVR12, including 144 of 157 (92% [CI, 86% to 96%]) with genotype 1a, 129 of 131 (99% [CI, 95% to 100%]) with genotype 1b, 18 of 18 (100% [CI, 82% to 100%]) with genotype 4, 8 of 10 (80% [CI, 44% to 98%]) with genotype 6, 68 of 70 (97% [CI, 90% to 100%]) with cirrhosis, and 231 of 246 (94% [CI, 90% to 97%]) without cirrhosis. Virologic failure occurred in 13 patients (4%), including 1 case of breakthrough infection and 12 relapses, and was associated with baseline NS5A polymorphisms and emergent NS3 or NS5A variants or both. Serious adverse events occurred in 9 (2.8%) and 3 (2.9%) patients in the active and placebo groups, respectively (difference <0.05 percentage point [CI, -5.4 to 3.1 percentage points]); none were considered drug related. The most common adverse events in the active group were headache (17%), fatigue (16%), and nausea (9%).. The study lacked an active-comparator control group and included relatively few genotype 4 and 6 infections.. Grazoprevir-elbasvir achieved high SVR12 rates in treatment-naive cirrhotic and noncirrhotic patients with genotype 1, 4, or 6 infection. This once-daily, all-oral, fixed-combination regimen represents a potent new therapeutic option for chronic HCV infection.. Merck & Co.

Phase I clinical and pharmacokinetic study of carzelesin (U-80244) given daily for five consecutive days.
Carzelesin (U-80244), one of the synthetic DNA minor groove binding cyclopropylpyrroloindole analogues, was selected for clinical development because of its high potency, promising antitumor activity in murine solid tumors and leukemia, and significant therapeutic efficacy against colon and rhabdomyosarcoma xenografts. In this Phase I study, carzelesin was given daily for 5 consecutive days to (a) determine the maximum tolerable dose (MTD) and the pattern of toxicity of this schedule; (b) define the pharmacokinetic profile of the parent, as was done for the intermediate compound U-76073 and the DNA-reactive agent U-76074; and (c) document any antitumor activity observed. Carzelesin was given as a 10-min infusion with a constant-rate infusion pump. Treatment was repeated every 4 weeks or when blood counts had recovered to normal values. The starting dose of 12 microgram/m2/day was escalated by 20-30% increments until the MTD (defined as the dose leading to grade 4 hematological or grade 3 nonhematological toxicity in at least two of six patients) was reached. Pharmacokinetic studies were planned on days 1 and 5 of the first cycle in at least two patients per dose level. Plasma levels of carzelesin, U-76073, and U-76074 were determined by high-performance liquid chromatography with UV detection and a detection limit of 0.5 ng/ml. Twenty-five patients were entered in the study, and 56 cycles were evaluable for hematological toxicity. Subsequent dose levels evaluated were 24, 30, 35, and 40 microgram/m2. Both neutropenia and thrombocytopenia were dose limiting and cumulative, with a high interpatient variability. Neutropenia occurred earlier (median time to neutrophil nadir and recovery, 15 and 29 days, respectively) than thrombocytopenia (median time to platelet nadir and recovery, 25 and >/=26 days, respectively); there were delays of treatment because of persisting thrombocytopenia in all patients treated at the MTD. At the MTD, the peak plasma concentrations of carzelesin were achieved at the end of the infusion and were higher than those found cytotoxic in vitro against tumor cell lines. Carzelesin was detectable up to a maximum of 1 h after the infusion. Smaller amounts of U-76073 were detectable for a maximum of 30 min only at the MTD, whereas U-76074 was never found. An 8-month partial remission was reported in one previously untreated patient with hepatocellular carcinoma at 40 microgram/m2. The MTD was fixed at 40 microgram/m2 daily; 35 and 30 micro Topics: Adult; Aged; Antineoplastic Agents; Area Under Curve; Benzofurans; Bronchial Spasm; Drug Administration Schedule; Duocarmycins; Female; Flushing; Humans; Hypersensitivity; Indoles; Male; Middle Aged; Nausea; Neoplasms; Neutropenia; Tachycardia; Thrombocytopenia; Treatment Outcome | 1996 |
Dose-ranging antiemetic evaluation of the serotonin antagonist RG 12915 in patients receiving anticancer chemotherapy.
RG 12915 is a potent, selective 5-HT3 receptor antagonist with a biologic half-life of 11-20 hours. RG 12915 prevents cisplatin-induced emesis in ferrets at doses of 0.03 mg/kg. Animal toxicology studies permitted safe testing in humans at doses of up to 2.0 mg/kg. This dose-ranging trial of intravenous RG 12915 was performed to determine the optimal dosage and adverse effects and to observe for antiemetic effects in patients receiving anticancer chemotherapy.. Twenty-six patients receiving chemotherapy likely to cause vomiting received a single intravenous dose of RG 12915 at a rate of 3 ml/minute beginning 60 minutes before chemotherapy. Four dose levels were explored: 0.25, 0.50, 1.0, and 2.0 mg/kg.. No dose-limiting toxicities were observed. All adverse effects were mild and transient and included discomfort at the infusion site, hyperglycemia, headache, serum aspartate transaminase (AST) and alanine transaminase (ALT) elevations, and sedation. Antiemetic efficacy was seen in patients receiving cisplatin at doses of greater than or equal to 100 mg/m2.. RG 12915 can be administered safely at the dose levels explored. Single intravenous doses of RG 12915 prevented or lessened emesis caused by chemotherapy, including cisplatin given at doses of greater than or equal to 100 mg/m2. RG 12915 warrants further testing. Of the doses tested, the 2.0 mg/kg dose is the most appropriate for further exploration.

The effect of prucalopride on gastric sensorimotor function and satiation in healthy volunteers.
Gastric motor function alterations have been implicated in the pathogenesis of functional dyspepsia with postprandial distress syndrome (PDS). Prucalopride, a 5-TH4 agonist, is known to stimulate gastrointestinal motility. We aimed to evaluate the effect of prucalopride on gastric sensorimotor function in healthy subjects (HV).. Barostat and intragastric pressure (IGP) measurements were performed in 17 HV (59% females, age 29.4 ± 2.7 y) after treatment with placebo or prucalopride (2 mg) (single-blind cross-over). Isobaric stepwise distensions and gastric sensations were assessed to determine gastric compliance and sensitivity. Gastric accommodation (GA) with the barostat was quantified before and after ingestion of 200 ml of a nutrient drink (ND). GA measured by IGP was quantified as the drop of IGP from baseline during the intragastric infusion of ND until maximal satiation (60 ml/min).. Prucalopride did not affect barostat assessed gastric compliance or sensitivity. No differences were observed in GA after prucalopride. During the barostat study, 10 min after the meal, 7 HVs reported significantly higher ratings for nausea after prucalopride (p < 0.001), and vomiting was induced in 4 of the HVs. A positive correlation was observed between the delta mean perception of nausea with the delta mean increase of intra-balloon volume before and after meal ingestion (r = 0.37, p = 0.03). During IGP measurements, no effect on nutrient tolerance was observed and increased cramp severity scores were observed which were associated with a significant increase of distal IGP (r = 0.78, p < 0.0001).. Prucalopride does not enhances gastric accommodation but it might increase sensitivity to gastric distention. Furthermore, the increase in sensitivity seems to be related to an increase in nausea with distension. Clinicaltrials.gov: NCT04429802.

WBQ5187, a Multitarget Directed Agent, Ameliorates Cognitive Impairment in a Transgenic Mouse Model of Alzheimer's Disease and Modulates Cerebral β-Amyloid, Gliosis, cAMP Levels, and Neurodegeneration.
Previously, we designed, synthesized, and evaluated a series of quinolone-benzofuran derivatives as multitargeted anti-Alzheimer's disease (anti-AD) compounds, and we discovered that WBQ5187 possesses superior anti-AD bioactivity. In this work, we investigated the pharmacokinetics of this new molecule, as well as its therapeutic efficacy in restoring cognition and neuropathology, in the APP/PS1 mouse model of AD. Pharmacokinetic analyses demonstrated that WBQ5187 possessed rational oral bioavailability, metabolic stability, and excellent blood-brain barrier (BBB) permeability. Pharmacodynamics studies indicated that a 12-week treatment with the lead compound at doses of 40 mg/kg or higher significantly enhanced the learning and memory performance of the APP/PS1 transgenic mice, and the effect was more potent than that of clioquinol (CQ). Furthermore, WBQ5187 notably reduced cerebral β-amyloid pathology, gliosis, and neuronal cell loss and increased the levels of cAMP in the hippocampus of these mice. The surrogate measures of emesis indicated that WBQ5187 had no effect at its cognitive effective doses. Overall, our results demonstrated that this compound markedly improves cognitive and spatial memory functions in AD mice and represents a promising pharmaceutical agent with potential for the treatment of AD.

Factors predictive of treatment-emergent adverse events of prucalopride: an integrated analysis of four randomized, double-blind, placebo-controlled trials.
This integrated analysis aimed to identify the factors associated with the most frequently re-ported treatment-emergent adverse events (TEAEs) in Asian and non-Asian patients with chronic constipation (CC) who receive prucalopride or placebo over 12 weeks.. Pooled data from four randomized, double-blind, placebo-controlled, multicenter, phase III studies (NCT00488137, NCT00483886, NCT00485940, and NCT01116206) on pa-tients treated with prucalopride 2 mg or placebo were ana-lyzed. The associations between predictors and TEAEs were evaluated based on a logistic regression model.. Overall, 1,821 patients (Asian, 26.1%; non-Asian, 73.9%) were analyzed. Prucalopride treatment was significantly as-sociated with diarrhea, headache, and nausea (p<0.001), but not with abdominal pain, compared with placebo. Differ-ences in the prevalence of TEAEs between prucalopride and placebo decreased greatly after the first day of treatment. Compared with non-Asians, Asians were more likely to expe-rience diarrhea and less likely to develop abdominal pain, headache, and nausea. Prior laxative use, CC duration, and body weight were not predictive of any of these TEAEs. Con-clusions Prucalopride treatment was positively associated with diarrhea, headache, and nausea. Asian patients tended to have a higher frequency of diarrhea but lower frequencies of headache, abdominal pain, and nausea compared with non-Asians. (Gut Liver, 2015;9208-213).

Plasma and red blood cell concentrations of amiodarone during chronic therapy.
Amiodarone and a metabolite, desethylamiodarone, were measured in plasma of 55 patients and in both plasma and red blood cell (RBC) in 28 patients who received chronic amiodarone treatment. The assay for amiodarone and desethylamiodarone was performed by high-pressure liquid chromatography. During chronic treatment, median plasma concentration of amiodarone was 2.80 micrograms/ml and desethylamiodarone was 2.20 micrograms/ml. In matched samples, plasma amiodarone concentration exceeded RBC amiodarone concentration (p less than 0.001) and the RBC-to-plasma concentration ratio averaged 0.31. The plasma desethylamiodarone concentration was not significantly different from its RBC concentration, and the RBC-to-plasma concentration ratio averaged 1.29. There was a linear correlation between plasma concentrations of amiodarone and desethylamiodarone (r = 0.82) and between RBC concentrations of drug and metabolite (r = 0.71). Drug or metabolite concentrations in plasma and RBCs correlated directly with daily dosage of amiodarone. Adverse side effects during chronic amiodarone therapy were related most strongly to RBC drug and metabolite concentrations. The group with adverse side effects had a significantly higher RBC concentration of amiodarone, 150 vs 0.75 micrograms/ml (p less than 0.001), than did patients free of adverse effects. After dosage reduction, side effects abated and plasma and RBC concentrations of drug and metabolite decreased. These data indicate that there is an expected range of amiodarone and desethylamiodarone concentrations during chronic treatment and that adverse side effects correlate best with RBC concentrations of drug and metabolite. Red cell concentrations may reflect the amount of unbound, free amiodarone and desethylamiodarone in plasma.

Long-term efficacy and toxicity of high-dose amiodarone therapy for ventricular tachycardia or ventricular fibrillation.
Amiodarone was administered to 154 patients who had sustained, symptomatic ventricular tachycardia (VT) (n = 118) or a cardiac arrest (n = 36) and who were refractory to conventional antiarrhythmic drugs. The loading dose was 800 mg/day for 6 weeks and the maintenance dose was 600 mg/day. Sixty-nine percent of patients continued treatment with amiodarone and had no recurrence of symptomatic VT or ventricular fibrillation (VF) over a follow-up of 6 to 52 months (mean +/- standard deviation 14.2 +/- 8.2). Six percent of the patients had a nonfatal recurrence of VT and were successfully managed by continuing amiodarone at a higher dose or by the addition of a conventional antiarrhythmic drug. One or more adverse drug reactions occurred in 51% of patients. Adverse effects forced a reduction in the dose of amiodarone in 41% and discontinuation of amiodarone in 10% of patients. The most common symptomatic adverse reactions were tremor or ataxia (35%), nausea and anorexia (8%), visual halos or blurring (6%), thyroid function abnormalities (6%) and pulmonary interstitial infiltrates (5%). Although large-dose amiodarone is highly effective in the long-term treatment of VT or VF refractory to conventional antiarrhythmic drugs, it causes significant toxicity in approximately 50% of patients. However, when the dose is adjusted based on clinical response or the development of adverse effects, 75% of patients with VT or VF can be successfully managed with amiodarone.

[Effects and side effects of benzbromaron in the initial treatment of hyperuricemia and gout. Results of a field study on 3899 patients].
In a collective of 3899 out-patients, the effect of uric acid reduction of benzbromarone was tested. Ten days after beginning of treatment, a uric acid concentration of 5.1 to 5.7 mg/100 ml had been obtained. Three months after beginning of therapy, uric acid values were at 4.9 mg/100 ml, independently of age and sex. As side-effects were observed:diarrhoea in 1% (n = 41) of the treated patients, furthermore, 0,8% (n = 31) complained of gastro-intestinal trouble such as pressure over the stomach, nausea, sensation of fullness and epigastric pain. Only in 2 of the 3899 patients (0.05%) the appearance of a renal colic was observed.
