fosaprepitant and Neoplasms

In recent years, chemotherapy-induced nausea and vomiting (CINV) has become the most common adverse effect of chemotherapy in oncology patients. The CINV may reduce the quality of life in mild cases, or even make the patients resist or delay further treatment. Fosaprepitant is a newly marketed neurokinin-1 receptor antagonist (NK-1RA), which can be combined with 5-hydroxytryptamine 3 receptor antagonists (5-HT3RAs) and dexamethasone to prevent chemotherapy-induced vomiting. The dimeglumine salt form of fosaprepitant can be utilized as an intravenous injectable drug, which surpasses aprepitant's oral admistration limits. Fosaprepitant is effective and safe in the control of CINV in cancer patients receiving highly emetogenic chemotherapy (HEC), and may be an alternative option for antiemetic therapy. In general, fosaprepitant is worthy of clinical promotion and has a large market potential. This article reviews the clinical studies on fosaprepitant conducted in recent years, with the aim of providing a basis for the rational clinical selection of antiemetic drugs.

Antiemetic prophylaxis for the prevention of chemotherapy-induced nausea and vomiting, and the development of new antiemetic drugs are expanding areas of research. However, studies of antiemetic prophylaxis in chemoradiotherapy have not been prioritised, and little is known about the proper timing, duration, and combination of antiemetic drugs for the prevention of chemoradiotherapy-induced nausea and vomiting (C-RINV).. The article summarises the available antiemetic studies, the evidence for antiemetic prophylaxis of C-RINV, and the future perspectives for antiemetic research in chemoradiotherapy.. Antiemetic prophylaxis for patients receiving concomitant chemoradiotherapy has, for many years, been an orphan research area. The distinction between acute and delayed nausea and vomiting does not apply to fractionated radiotherapy, and prophylaxis should be considered to cover the entire course of treatment and not only the acute and delayed chemotherapy-induced nausea and vomiting. The best prophylaxis in women receiving fractionated radiotherapy and concomitant weekly cisplatin is a combination of the neurokinin receptor antagonist fosaprepitant with palonosetron and dexamethasone. Even with this three-drug combination nausea is a significant problem and the effect of multi-receptor targeting antiemetics such as olanzapine and amisulpride should be explored in this setting.

Intravenous fosaprepitant dimeglumine (Emend(®) for injection, IVEmend(®); henceforth referred to as fosaprepitant) is a prodrug of and is rapidly converted to the antiemetic aprepitant, and is approved in several countries worldwide (as part of an antiemetic regimen) for the prevention of nausea and vomiting associated with highly and moderately emetogenic chemotherapy (HEC and MEC). This narrative review discusses the pharmacological properties of intravenous fosaprepitant and its clinical efficacy and tolerability in the prevention of nausea and vomiting associated with HEC and MEC. In large, randomized phase III clinical trials, a single intravenous dose of fosaprepitant 150 mg was an effective and generally well tolerated addition to an antiemetic regimen that included dexamethasone and a serotonin 5-HT3 receptor antagonist in adult cancer patients undergoing treatment with HEC or MEC. It was also noninferior to an oral aprepitant-based regimen in adult cancer patients undergoing HEC treatment. The tolerability profile of a fosaprepitant-based regimen was typical of that in patients receiving emetogenic chemotherapy, and adverse events were generally consistent with those observed with an aprepitant-based regimen. Fosaprepitant provides a useful addition to antiemetic therapy regimens.

Chemotherapy induced nausea and vomiting (CINV) is a common complication in the treatment of patients with cancer. The introduction of the first in class neurokinin-1 receptor antagonist aprepitant provided additive control on CINV in combination to existing antiemetics. Due to formulation issues, aprepitant is only available for oral administration. Fosaprepitant, a prodrug of aprepitant, was introduced to the market in 2008 as an intravenous bioequivalent to aprepitant.. This review examines the chemical development of fosaprepitant, its pharmacokinetic properties, approved uses and potential applications.. The reader will get up-to-date information on the pharmacology and clinical uses of fosaprepitant. Clinical studies have demonstrated pharmacokinetic bioequivalence of aprepitant 125 mg to fosaprepitant 115 mg, as well as comparable efficacy in prevention of acute and delayed emesis following the first day of chemotherapy regimens.. Fosaprepitant is an intravenous prodrug of aprepitant that offers a new alternative to patients with CINV. Currently, fosaprepitant can substitute oral aprepitant in day 1 of a 3-day regimen. Current studies show that a single-day fosaprepitant regimen is also bioequivalent to the 3-day aprepitant regimen; this could significantly simplify the care for CINV patients in the future.

Advances in antiemetic therapy for chemotherapy-induced emesis have resulted in improved protection against symptoms occurring within 24 h of chemotherapy. However, the vomiting which tends to occur beyond 24 h after chemotherapy (delayed-phase vomiting) is still relatively poorly controlled by the currently available drugs, suggesting that more than one mechanism may mediate these symptoms. The standard antiemetic regimen currently recommended for prevention of chemotherapy-induced emesis includes a serotonin (5-HT(3)) antagonist and a corticosteroid. The neurokinin-1 (NK(1)) antagonist aprepitant represents a new class of antiemetic currently in clinical development. Using data obtained in 2 Phase II clinical trials of aprepitant in patients receiving chemotherapy based on the highly emetogenic chemotherapeutic agent cisplatin, we compared the time course of antiemetic effect of aprepitant, a 5-HT(3) antagonist, or a combination of both. Over the entire observation period (up to 7 days post-cisplatin), patients who received the NK(1) antagonist had a superior prevention of emesis. However, in the first 24 h after cisplatin, emesis occurred in fewer patients who received the 5-HT(3) antagonist than in patients who did not receive this class of drug. Furthermore, the majority of treatment failures in patients who received the NK(1) antagonist occurred within the first 8-12 h of chemotherapy, whereas the treatment failures in patients who received a 5-HT(3) antagonist were more evenly distributed over time. Patients who received both drugs had superior control of symptoms compared with patients who received one or the other. The difference in the time course of emesis blockade observed with two different classes of receptor antagonists provides substantial evidence for involvement of separate pathophysiological mechanisms in chemotherapy-induced vomiting. Serotonin mediates the early vomiting process that occurs within 8-12 h following cisplatin-based chemotherapy, after which time substance P acting at NK(1) receptors becomes the dominant mediator of vomiting

Highly emetogenic chemotherapy induces emesis in cancer patients without prophylaxis. The purpose of this study was to evaluate the efficacy and safety of a fosaprepitant-based triple antiemetic regimen for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients with solid malignant tumors, determine risk factors and externally validate different personalized risk models for CINV.. This phase III trial was designed to test the non-inferiority of fosaprepitant toward aprepitant in cancer patients who were to receive the first cycle of single-day cisplatin chemotherapy. The primary endpoint was complete response (CR) during the overall phase (OP) with a non-inferiority margin of 10.0%. Logistic regression models were used to assess the risk factors of CR and no nausea. To validate the personalized risk models, the accuracy of the risk scoring systems was determined by measuring the specificity, sensitivity and area under the receiver operating characteristic (ROC) curve (AUC), while the predictive accuracy of the nomogram was measured using concordance index (C-index).. A total of 720 patients were randomly assigned. CR during the OP in the fosaprepitant group was not inferior to that in the aprepitant group (78.1% vs. 77.7%, P = 0.765) with a between-group difference of 0.4% (95% CI, -5.7% to 6.6%). Female sex, higher cisplatin dose (≥ 70 mg/m. Fosaprepitant-based triple prophylaxis demonstrated non-inferior control for preventing CINV in patients treated with cisplatin-base chemotherapy. Female cancer patients without a history of alcohol consumption, with larger BSA and received high-dose cisplatin might be more vulnerable to CINV. Three personalized prediction models were well-validated and could be used to optimize antiemetic therapy for individual patients.

Results from a phase III, randomized, double-blind, active comparator-controlled, parallel-group trial evaluating fosaprepitant for the prevention of chemotherapy-induced nausea and vomiting (CINV) found that a single-day, triple-antiemetic fosaprepitant regimen resulted in a significantly higher proportion of patients achieving a complete response (CR; no vomiting or rescue medication use) in the delayed phase (25-120 h after chemotherapy initiation), compared with a 3-day control regimen ( ClinicalTrials.gov , NCT01594749). As the risk for CINV is dependent on chemotherapy regimen and generally guided by tumor type, this post hoc analysis evaluated the efficacy and safety of this regimen by cancer subpopulations (gastrointestinal [GI] or colorectal, lung, breast, and gynecologic cancers).. Subjects with confirmed cancer who were naive to highly and moderately emetogenic chemotherapy (HEC and MEC) and were scheduled to receive intravenous (IV) anthracycline-cyclophosphamide (AC)-based MEC on the first day of chemotherapy were randomly assigned to receive oral ondansetron and oral dexamethasone plus either a single IV dose of fosaprepitant 150 mg (fosaprepitant regimen) or placebo (control regimen). The primary efficacy end point was the proportion of subjects achieving CR in the delayed phase. CR rates in the overall and acute phases (0-120 h and 0-24 h after MEC initiation, respectively) were assessed as secondary end points. Safety and tolerability were also assessed.. CR rates in the delayed phase favored the fosaprepitant regimen over the control regimen across the GI/colorectal, lung, breast, and gynecologic cancer subgroups (range, 6.2-22%); similar findings were observed for CR in the overall phase. CR in the acute phase was high for all groups (≥87%). The fosaprepitant regimen was well tolerated in all cancer subgroups.. This post hoc analysis indicated that a single-day fosaprepitant regimen was effective in preventing CINV in patients receiving MEC, regardless of cancer type..

Fosaprepitant is a neurokinin-1 receptor antagonist, approved for the prevention of chemotherapy-induced nausea and vomiting. The data on the use of fosaprepitant in children are limited and therefore we conducted a phase III randomized controlled trial.. Children aged 1-12 years scheduled to receive moderately or highly emetogenic chemotherapy were randomly assigned to arm-A (fosaprepitant) or arm-B (placebo). Children recruited to arm-A received intravenous ondansetron plus dexamethasone followed by fosaprepitant infusion. Children recruited to arm-B received the same drugs as those given to children in arm-A, except that fosaprepitant was substituted with a placebo. Ondansetron and dexamethasone were continued for 48 hours after completion of chemotherapy. The primary end point of the study was to determine the proportion of patients who achieved a complete response (CR), defined as no vomiting, no retching, and no use of rescue medication, during the 24-120 hours (delayed phase) after administration of the last dose of chemotherapy. Secondary end points were the proportion of patients who achieved a CR during the acute phase (0-24 hours) and overall after administration of the last dose of chemotherapy.. One-hundred-sixty-three patients were analyzed (81 in the fosaprepitant arm and 82 in the placebo arm). CR rates were significantly higher in the fosaprepitant arm compared to those in the placebo arm during the acute phase (86% vs 60%, P < 0.001), delayed phase (79% vs 51%, P < 0.001), and overall phase (70% vs 41%, P < 0.001). Three (4%) patients in the fosaprepitant arm and sixteen (20%) in the placebo arm required rescue anti-emetics (P = 0.0017).. Addition of fosaprepitant to ondansetron and dexamethasone improved chemotherapy-induced vomiting control in children treated with moderately or highly emetogenic chemotherapy.

Current antiemetic regimens are less effective in children than in adults. Fosaprepitant was recently approved for prevention of chemotherapy-induced nausea and vomiting (CINV) in children aged six months and older.. The pharmacokinetic (PK)/pharmacodynamic (PD) profile, safety, and tolerability of a single intravenous dose of fosaprepitant administered concomitantly with ondansetron with/without dexamethasone were evaluated in pediatric patients with cancer receiving emetogenic chemotherapy. PK/PD from three doses of fosaprepitant (3.0, 1.2, and 0.4 mg/kg, up to 150, 60, and 20 mg, respectively) were compared with placebo in 2- to 17-year-old subjects; an open-label amendment evaluated a fourth dose (5.0 mg/kg, up to 150 mg) in those under 12 years old. Historical adult PK data were used for comparison. Efficacy was measured as an exploratory endpoint.. PK data were evaluable for 167/234 subjects who completed cycle one. Aprepitant exposures were dose proportional; adolescents (12 to 17 years) receiving fosaprepitant 150 mg had exposures similar to adults at the same dose. Higher weight-normalized doses (5 mg/kg) were necessary for children aged < 12 years to achieve comparable adult exposures. The adverse event profile was typical of cancer patients receiving emetogenic chemotherapy. Drug-related adverse events were reported in 16 (6.8%) subjects, with hiccups being most common (n = 5; 2.1%).. Intravenous fosaprepitant was well tolerated by pediatric subjects with cancer, and dose-proportional exposures were observed. Subjects < 12 years old required higher doses to achieve comparable adult exposures.

Fosaprepitant improved prevention of chemotherapy-induced nausea and vomiting (CINV) in a randomized, double-blind phase III trial (PN031). This post hoc analysis explored factors that may have influenced response.. Adult subjects (N = 1000) scheduled to receive non-anthracycline and cyclophosphamide (AC) moderately emetogenic chemotherapy (MEC) on day 1 were randomly assigned 1:1 to a single-dose, 150-mg intravenous fosaprepitant regimen or a control regimen. Both regimens included dexamethasone and ondansetron on day 1, with ondansetron continuing through day 3 in the control arm only. Complete response (CR; no vomiting and no rescue medication) rates in the acute, delayed, and overall phases (0-25, 25-120, and 0-120 h, respectively) were analyzed by chemotherapy type (carboplatin-based vs non-carboplatin-based), chemotherapy duration (single-day vs multiple-day), and baseline characteristics.. Most subjects received single-day chemotherapeutic regimens (70.6%), which were mainly carboplatin-based (67.6%). CR with fosaprepitant was consistent (76-80%) during the delayed and overall phases in carboplatin-based and non-carboplatin-based subgroups and in subgroups receiving single-day or multiple-day MEC regimens. Treatment effects favored fosaprepitant for the carboplatin-based versus the non-carboplatin-based group during the delayed phase (14.1 vs 6.5%; p = 0.06), and for the single-day versus the multiple-day subgroup during the delayed (13.2 vs 3.2%; p = 0.02) and overall phases (12.8 vs 4.0%; p = 0.06).. This exploratory analysis confirms that single-dose fosaprepitant is effective for the prevention of CINV in subjects receiving carboplatin or non-carboplatin in both single- and multiple-day non-AC MEC chemotherapy regimens. This trial is registered at ClinicalTrials.gov , number NCT01594749.

Evaluate safety of HTX-019, a novel polysorbate 80- and synthetic surfactant-free intravenous formulation of neurokinin 1 receptor antagonist aprepitant for chemotherapy-induced nausea and vomiting.. Two open-label, randomized, two-way crossover studies evaluated treatment-emergent adverse events (TEAEs) in 200 healthy subjects. Subjects received HTX-019 130 mg (30-min infusion) and fosaprepitant 150 mg (20- or 30-min infusion), with ≥7-day washout between doses.. Less than or equal to 30 min after start of infusion, TEAEs occurred in 5 (3%) HTX-019 and 30 (15%) fosaprepitant recipients. No HTX-019 recipients had infusion-site adverse events, versus 15 (8%) fosaprepitant recipients. Treatment-related dyspnea occurred in one HTX-019 and six fosaprepitant recipients. No severe/serious TEAEs occurred; all TEAEs resolved.. HTX-019 may provide a safer aprepitant formulation than fosaprepitant for chemotherapy-induced nausea and vomiting prevention.

We evaluated the efficacy and safety of single-dose fosaprepitant in combination with intravenous granisetron and dexamethasone.. Patients receiving chemotherapy including cisplatin (≥70 mg/m(2)) were eligible. A total of 347 patients (21% had received cisplatin with vomiting) were enrolled in this trial to receive the fosaprepitant regimen (fosaprepitant 150 mg, intravenous, on day 1 in combination with granisetron, 40 μg/kg, intravenous, on day 1 and dexamethasone, intravenous, on days 1-3) or the control regimen (placebo plus intravenous granisetron and dexamethasone). The primary end point was the percentage of patients who had a complete response (no emesis and no rescue therapy) over the entire treatment course (0-120 h).. The percentage of patients with a complete response was significantly higher in the fosaprepitant group than in the control group (64% versus 47%, P = 0.0015). The fosaprepitant regimen was more effective than the control regimen in both the acute (0-24 h postchemotherapy) phase (94% versus 81%, P = 0.0006) and the delayed (24-120 h postchemotherapy) phase (65% versus 49%, P = 0.0025).. Single-dose fosaprepitant used in combination with granisetron and dexamethasone was well-tolerated and effective in preventing chemotherapy-induced nausea and vomiting in patients receiving highly emetogenic cancer chemotherapy, including high-dose cisplatin.

Recent studies have suggested that antiemetic therapy with a triple combination of the neurokinin-1 receptor antagonist MK-869, a serotonin (5-HT(3)) antagonist, and dexamethasone provides enhanced control of cisplatin-induced emesis compared with standard therapy regimens. The authors compared the antiemetic activity of a dual combination of MK-869 and dexamethasone with that of a standard dual combination of ondansetron and dexamethasone to characterize further the efficacy and tolerability profile of MK-869.. This was a multicenter, double-blind, randomized, active agent-controlled study of 177 cisplatin-naïve patients with malignant disease. On Day 1, MK-869 was given intravenously as its water-soluble prodrug, L-758,298. Patients were randomized to one of three groups as follows. Group I received L-758,298 100 mg intravenously (i.v.), then dexamethasone 20 mg i.v., and cisplatin >or= 70 mg/m(2) on Day 1 followed by 300 mg MK-869 (tablet) orally on Days 2-5; Group II received L-758,298 100 mg i.v., then dexamethasone 20 mg i.v., and cisplatin >or= 70 mg/m(2) on Day 1 followed by placebo on Days 2-5; and Group III received ondansetron 32 mg i.v., then dexamethasone 20 mg i.v., and cisplatin >or= 70 mg/m(2) on Day 1 followed by placebo on Days 2-5. Emesis was recorded over Days 1-5 in a diary. Nausea was assessed every 24 hours by visual analog scale. Additional medication was available for emesis or nausea at any time. The primary efficacy parameters of interest were the proportion of patients without emesis and the proportion without emesis or rescue therapy on Day 1 (acute phase) and on Days 2-5 (delayed phase).. No serious adverse events were attributed to L-758,298 or MK-869. On Day 1, the proportions of patients with no emesis and no use of rescue medication were 44% of patients in Group I, 36% of patients in Group II, 40% of patients in Groups I and II combined, and 83% of patients in Group III (P < 0.001 for Group III vs. the combined Groups I and II). The proportions of patients with no emesis and no use of rescue medication on Days 2-5 were 59% of patients in Group I, 46% of patients in Group II, and 38% of patients in Group III (P < 0.05 for Group I vs. Group III). The proportions of patients who were without emesis on Day 1 were 49% of patients in Group I, 47% of patients in Group II, and 84% of patients in Group III (P < 0.01 for Group I or II vs. Group III). On Days 2-5, however, the proportions of patients who were without emesis on Days 2-5 were 65% of patients in Group I, 61% of patients in Group II, and 41% of patients in Group III (P < 0.05 for Group I or II vs. Group III). Nausea scores in the acute phase were lower for Group III than for Group I, Group II, or Groups I and II combined (P < 0.05), although there was no significant difference among groups either for the delayed phase or overall for Days 1-5.. Although the L-758,298 and dexamethasone combination reduced acute (Day 1) emesis compared with historic rates, dual therapy with ondansetron and dexamethasone was superior in controlling acute emesis. Continued dosing with MK-869 may enhance control of other measures of delayed emesis, such as the use of rescue medication, although confirmation is required before a definitive conclusion may be drawn. MK-869 given as dual therapy with dexamethasone was superior to ondansetron with dexamethasone for the control of delayed emesis (Days 2-5) and control of the need for rescue medication on Days 2-5.

At our institution, an increased incidence of hypersensitivity reactions was reported following standardization of fosaprepitant as the preferred agent for the prophylaxis of chemotherapy induced nausea and vomiting (CINV) caused by highly emetogenic therapies. The purpose of this evaluation was to assess the incidence of systemic hypersensitivity reactions (HSRs) to fosaprepitant infusions compared to available literature.. This evaluation is a retrospective review of electronic health records of adult patients who received their first dose of fosaprepitant for CINV prophylaxis beginning January 1, 2017 through June 30, 2017 at the University of Colorado Cancer Center outpatient infusion center. Subjects were identified using medication administration reports. Individual chart reviews were performed for all patients who received fosaprepitant during the specified timeframe and had a reaction reported on the same date.. A total of 868 patients received fosaprepitant in the outpatient infusion center during the study time period. Four patients (0.461%) had a systemic HSR attributed to fosaprepitant. Two of the reactions were reported as HSRs in the adverse reaction reporting system and two were found in provider notes during chart review. Due to the small sample size, risk factors for HSRs to fosaprepitant were not able to be determined.. The incidence of HSRs to fosaprepitant at our institution was found to be consistent with the <1% incidence currently noted in literature. Based on these findings, opportunities have been identified for education on fosaprepitant-associated HSRs, proper documentation and patient-specific precautions.

To evaluate the impact on cost, time, resource use, and clinic workflow of converting the route of drug administration from a neurokinin-1 receptor antagonist (NK-1 RA) 30-min intravenous (IV) infusion to aprepitant IV, and more specifically to IV push, within a multicenter community oncology practice.. This was a retrospective, multicenter time, motion, and resource/cost evaluation study. Conversion to aprepitant IV was determined by calculating number of doses of aprepitant IV versus fosaprepitant administered in patients receiving moderately or highly emetogenic chemotherapy regimens. Operational advantages (i.e., supply costs, time saved) of switching from fosaprepitant IV infusion to aprepitant administered as a 2-min IV push were assessed.. A total of 12,908 doses of aprepitant IV 130 mg were administered at 13 Rocky Mountain Cancer Centers clinics over an 18-month period. Conversion from fosaprepitant to aprepitant IV reached 90% after 9 months of aprepitant IV initiation. Supply costs per administration were reduced ($2.51 to $0.52) when aprepitant was prepared as an IV push versus an NK-1 RA infusion. The overall time savings per administration of aprepitant was reduced by 90% (from 36.5 to 3.5 min, 33 min saved) as an IV push rather than an infusion. Most of the time saved per administration (30 min) pertained to the infusion nurse, and 3 min was saved by the pharmacy technician.. Successful conversion to aprepitant, and specifically to a 2-min IV push, provides time, cost, and resource savings, improves operational efficiency, and avoids the negative impact of potential future IV fluid shortages.. Chemotherapy-induced nausea and vomiting (CINV) can have a major impact on quality of life for patients receiving chemotherapy. Intravenous (IV) aprepitant is an approved neurokinin-1 receptor antagonist (NK-1 RA) that has been effective and safe when administered as part of a guideline-recommended regimen in patients receiving chemotherapy. In addition to being approved as a 30-min infusion, aprepitant IV is the only NK-1 RA approved for administration as a 2-min injection. These factors contributed to Rocky Mountain Cancer Centers (RMCC), which is a physician-owned community oncology practice, evaluating the impact on cost, time, and resource use of converting from a 30-min infusion of fosaprepitant to aprepitant IV, and more specifically a 2-min injection. Within 9 months of implementing aprepitant IV at RMCC, the percent utilization compared to fosaprepitant reached over 90%, signifying a successful conversion within the practice. Furthermore, a 2-min injection of aprepitant IV resulted in several operational advantages compared to a 30-min infusion. When accounting for all 13 clinics within RMCC, total monthly time savings to the practice would be over 28,000 min, or approximately 60 workdays per month of saved time. This new workflow is more efficient and allows for pharmacy technicians to complete other necessary tasks in the pharmacy such as cleaning, organizing, managing inventory, drug ordering, and charge/documentation corrections. Time saved by the nurses could be used for enhanced patient care, thoroughly reviewing chemotherapy or other orders, and assisting other nurses.

High-dose myeloablative conditioning prior to autologous hematopoietic stem cell transplantation (autoHSCT) in pediatric patients is usually highly emetogenic. The antiemetic neurokinin-1 receptor antagonist fosaprepitant was safe and effective in children receiving highly emetogenic chemotherapy. Data on fosaprepitant during autoHSCT in children are currently not available.. A total of 35 consecutive pediatric patients, who received an antiemetic prophylaxis with fosaprepitant (4 mg/kg; single dose, max. 1 x 150 mg/kg BW) and ondansetron (24-hours continuous infusion; 8-32 mg/24h) or granisetron (2 x 40 µg/kg∙d. Clinical adverse events and clinically relevant increases/decreases of laboratory markers were similarly low and did not significantly differ between the two study groups (. The fosaprepitant-based antiemetic prophylaxis was safe, well tolerated and significantly reduced vomiting in children undergoing highly emetogenic chemotherapy prior to autoHSCT. Prospective randomized trials are necessary to confirm these results.

Chemotherapy-induced nausea and vomiting (CINV) belong among the most burdensome side effects in hemato-oncology. Mostly, a combination of ondansetron and dexamethasone is used as antiemetic prophylaxis in pediatric patients undergoing emetogenic chemotherapy. However, dexamethasone is prohibited in different pediatric chemotherapy protocols. Currently, data on the use of ondansetron with the new antiemetic agent fosaprepitant without dexamethasone is not available for pediatric patients.. In this non-interventional observation study, 79 pediatric patients with a median age of 8.0 years (range 0.5-17.9 years) who received a CINV prophylaxis regimen with either fosaprepitant (4 mg/kg; maximum 150 mg) and ondansetron (as 24-h continuous infusion) (n = 40; fosaprepitant group/FG) or ondansetron only (n = 39; control group/CG) during moderately or highly emetogenic chemotherapy were analyzed. The groups were analyzed and compared for frequency of vomiting, administered doses of on-demand antiemetic dimenhydrinate and adverse events during the acute (0-24 h after chemotherapy administration) and delayed (> 24 h-120 h) CINV phases.. A total of 112 and 116 chemotherapy blocks were analyzed in the fosaprepitant and the control group, respectively. The emetogenic potential of the administered chemotherapy did not significantly differ (p = 0.8812) between the two cohorts. In the acute CINV phase, the percentage of patients experiencing vomiting (n = 26 patients) and the vomiting events were significantly higher (p = 0.0005 and p < 0.0001, respectively) in the CG (n = 26 patients (66.7%); 88 events) compared with the FG (n = 10 patients (25.0%); 37 events). In the delayed CINV phase, the percentage of patients experiencing vomiting and the vomiting events were also significantly higher (p = 0.0017 and p < 0.0001, respectively) in the CG (n = 31 patients (79.5%); 164 events) compared with the FG (n = 17 patients (42.5%); 103 events). Additionally, significantly more dimenhydrinate doses were administered in the CG compared with the FG patients (n = 322/n = 198; p < 0.0001). The occurrence of adverse events did not significantly differ between the two groups (p > 0.05).. Fosaprepitant (4.0 mg/kg) in addition to ondansetron, without application of dexamethasone, was well tolerated, safe, effective and superior to ondansetron only as CINV prophylaxis in pediatric patients during moderately and highly emetogenic chemotherapy.

Fosaprepitant (Emend®) is an antiemetic frequently used for the prevention of chemotherapy-induced nausea and vomiting. We previously documented an overall 28.7% incidence of infusion-site reactions in patients receiving fosaprepitant via peripheral venous access. These data resulted in a practice change within our institution; fosaprepitant is administered in more dilute concentrations over 30 min to prevent these adverse events. This retrospective study explored the impact of this practice change on the incidence of infusion-site reactions.. Medical records of patients with cancer receiving intravenous fosaprepitant through a peripheral intravenous line were reviewed. The primary objective of this study was to compare the incidence of infusion-site reactions before the practice change to the incidence after the practice change. Data collection included demographics, fosaprepitant infusion information, and grading of reactions.. Between September 2013 and December of 2013, charts of 122 patients receiving intravenous fosaprepitant through a peripheral line at the The Arthur G. James Cancer Hospital at The Ohio State University were reviewed. We found a 5.74% incidence of infusion-site reactions which is significantly lower than the prechange incidence of 28.7% (p < 0.001).. Infusion-site reactions were significantly reduced when fosaprepitant was diluted to 150 mg/250 ml and infused over 30 min. We recommend oncology pharmacists consider using the more dilute fosaprepitant preparation and 30 min infusion duration when administering via a peripheral intravenous line to improve patient tolerance.

Chemotherapy-induced nausea and vomiting diminishes quality of life and increases healthcare resource use. This retrospective medical records analysis evaluated hydration requirements with emetogenic chemotherapy.. Cancer patients received moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC), and antiemetics palonosetron or granisetron extended-release subcutaneous (GERSC), neurokinin 1 receptor antagonist and dexamethasone. Unscheduled hydration event rates were determined.. For 186 patients (92 palonosetron, 94 GERSC) overall, mean hydration rate was significantly higher with palonosetron (0.6 vs 0.2; p = 0.0005). Proportion of patients with ≥1 hydration event was significantly higher with palonosetron overall (54 vs 33%; p = 0.0033) and in cycles 2-4 and the HEC subgroup.. GERSC within a three-drug antiemetic regimen may reduce unscheduled hydration requirements with MEC or HEC.

HTX-019 [CINVANTI. This retrospective review involved six sites in Alabama, USA. Analyzed patients were 18-94 years old with an Eastern Cooperative Oncology Group performance status ranging from 0 to 4. Seventy-six chemotherapy regimens were utilized (emetogenicity high, n = 35; moderate, n = 35; low, n = 6) and patients received HTX-019 130 mg only or switched from fosaprepitant 150 mg to HTX-019 130 mg within a three-drug antiemetic regimen with a 5-hydroxytryptamine type 3 RA and dexamethasone. HTX-019 was administered via IV push. Electronic medical records of patients receiving HTX-019 were queried for nursing and medical documentation associated with infusion-site adverse events (ISAEs). The detailed notes were also reviewed for any discontinuation of HTX-019 or substitution of HTX-019 with another NK-1 RA.. The HTX-019 safety profile was analyzed on the basis of 2066 IV push administrations in 591 cancer patients (most common diagnoses: lung, n = 107; breast, n = 100; colon, n = 92). No clinically significant ISAEs or adverse events associated with HTX-019 were reported. Also, no patients discontinued HTX-019 treatment, and none switched from HTX-019 to another NK-1 RA.. This is the first study to demonstrate that HTX-019 can be safely administered via IV push in patients with cancer receiving emetogenic chemotherapy while negating the need for fluid bags, which are scarce..

Optimal pain management often requires multiple pharmacological interventions with the goal of disrupting the pain-signaling pathway and targeting the underlying pathophysiology. Off label use of nonpain medications may have a role in treating refractory pain syndromes.. We report a case of a 60-year-old female with refractory nociceptive and neuropathic pain. Conventional therapies were either ineffective or fraught with side effects. Given the underlying inflammatory nature of her pain syndrome, and the role of substance P (SP) in pain transmission and modulation, we decided to use fosaprepitant, an SP and neurokinin-1 (NK1) receptor antagonist. The patient tolerated fosaprepitant and experienced acceptable analgesia without compromising her mental functioning.. Study and analysis of a case of a patient with refractory mixed, nociceptive, and neuropathic pain syndrome treated with fosaprepitant.. Fosaprepitant is a potentially novel adjuvant therapy for the treatment of refractory inflammatory pain syndromes in palliative care.

Fosaprepitant dimeglumine (Emend IV®) is an IV antiemetic that may be beneficial to patients receiving highly emetogenic regimens. Aprepitant (Emend®) is an oral medication that is administered for three consecutive days, whereas fosaprepitant is a single-dose IV medication that is administered on the day of chemotherapy for 20-30 minutes (depending on the IV access type). Fosaprepitant may be useful, yet it can also present a risk for hypersensitivity reactions and phlebitis. Oncology nurses must be aware of the signs and symptoms of these potential adverse events to properly care for their patients.

Fosaprepitant is an antiemetic used for chemotherapy-induced nausea and vomiting. We recently reported increased infusion site adverse events (ISAE) in a cohort of breast cancer patients receiving chemotherapy with doxorubicin and cyclophosphamide (AC). In this current study, we evaluated the venous toxicity of fosaprepitant use with non-anthracycline platinum-based antineoplastic regimens.. A retrospective review was conducted of the first 81 patients initiated on fosaprepitant among patients receiving highly emetogenic chemotherapy, on or after January 1, 2011 at Mayo Clinic Rochester. None of these regimens included an anthracycline. Data collected included baseline demographics, chemotherapy regimen, type of intravenous access and type, and severity of ISAE. Data from these patients were compared to previously collected data from patients who had received AC. Statistical analysis using χ 2 and univariate logistic regression was used to evaluate the association between treatment regimen, fosaprepitant, and risk of ISAE.. Among these 81 patients, the incidence of ISAE was 7.4% in the non-anthracycline platinum group. The most commonly reported ISAE were swelling (3%), extravasation (3%), and phlebitis (3%). When stratified by regimen, fosaprepitant was associated with a statistically significant increased risk of ISAE in the anthracycline group (OR 8.1; 95% CI 2.0-31.9) compared to the platinum group.. Fosaprepitant antiemetic therapy causes significant ISAE that are appreciably higher than previous reports. Patients receiving platinum-based chemotherapy appear to have less significant ISAE than do patients who receive anthracycline-based regimens.

At our hospital, we use aprepitant for nausea and vomiting when administering highly emetic anticancer agents, according to "Guidelines for the Appropriate Use of Antiemetic Agents" given by the Japan Society of Clinical Oncology. We initiated the intravenous administration of fosaprepitant for better compliance compared with aprepitant; however, we observed phlebitis after the infusion of fosaprepitant. Therefore, we investigated measures to reduce phlebitis associated with the infusion of fosaprepitant. For the first premedication, fosaprepitant (150 mg) was dissolved in 100 mL of saline and administered for 30 minutes; 1 of 2 patients showed grade 4 phlebitis. For the modified premedication, fosaprepitant, dexamethasone, and 5- HT(3) antagonist were dissolved in 100 mL of saline and administered for 30 minutes. The modified premedication was administered to a total of 27 patients; 5 patients developed mild phlebitis (grade 1), but infusion could be continued by treating their phlebitis with a hot pack. We used a combination of dexamethasone and 5-HT(3) antagonist with fosaprepitant as a modified premedication in order to avoid drug-induced vascular damage, which resulted in the pH decreasing to 6.20-7.55 (close to neutral) and a shorter infusion time.

Fosaprepitant is known to cause infusion-site reactions. However, there is limited data regarding these reactions including the effect of peripheral intravenous administration or other potential factors on their incidence. This single-institution retrospective study was undertaken to investigate the incidence of infusion-site reactions with single-dose intravenous (IV) fosaprepitant when given through a peripheral line prior to administration of chemotherapy. Risk factors for the development of infusion-site reactions with fosaprepitant were also explored.. Medical records of patients with cancer receiving IV fosaprepitant through a peripheral line were reviewed. The primary objective of this study was to estimate the incidence of infusion-site reactions at our institution. Data collection included demographics, fosaprepitant infusion information, and grading of reactions.. We found a 15 % incidence of infusion-site reactions among all peripherally administered doses of fosaprepitant. The 50 reactions occurred in 43 unique patients representing an incidence per patient of 28.7 % (43/150; 95 % confidence interval (CI) 21.6-36.6). Factors found to be associated with infusion-site reactions included age [odds ratio (OR) 0.97 (95 % CI 0.94-0.99)], location of IV line [OR forearm vs. hand 0.41 (95 % CI 0.20-0.85); OR antecubital fossa vs. hand 0.31 (95 % CI 0.11-0.87)], and simultaneous maintenance IV fluid rate ≥100 mL/h during fosaprepitant infusion [OR 0.19 (95 % CI 0.08-0.44)].. The incidence of infusion-site reactions with peripherally administered fosaprepitant as seen in this study is higher than that reported in the package insert. Risk factors for developing infusion-site reactions in our patient population include age, location of IV line, and simultaneous maintenance IV fluid rate of <100 mL/h.

Antiemetic triplet therapy including dexamethasone (DEX) is widely used for patients receiving highly emetogenic chemotherapy (HEC). In Japan, the appropriate dose of DEX has not been established for this combination.. To assess the efficacy and safety of increased-dose DEX, we retrospectively examined patients receiving HEC with antiemetic triplet therapy.. Twenty-four patients (fosaprepitant group) were given an increased-dose of DEX (average total dose: 45.8mg), fosaprepitant, and 5-HT3 antagonist. A lower-dose of DEX (33.6mg), oral aprepitant, and 5-HT3 antagonist were administered to the other 48 patients (aprepitant group). The vomiting control rates in the fosaprepitant and aprepitant groups were 100% and 85.4% in the acute phase, and were 75.0% and 64.6% in the delayed phase. The incidences of toxicity were similar comparing the two groups.. Triplet therapy using an increased-dose of DEX is suggested to be safe and effective for patients receiving HEC.
