fosaprepitant and Drug-Related-Side-Effects-and-Adverse-Reactions

The role of the neurokinin-1 (NK-1) receptor antagonists in the prevention of radiation-induced nausea and vomiting has not been established. The purpose of the GAND-emesis study was to investigate the efficacy and safety of fosaprepitant in combination with palonosetron and dexamethasone in the prevention of nausea and vomiting during 5 weeks of fractionated radiotherapy and concomitant weekly cisplatin in patients with cervical cancer.. This investigator initiated, multinational, randomised, double-blind, placebo-controlled phase 3 trial, included women with cervical cancer scheduled to receive fractionated radiotherapy and weekly cisplatin 40 mg/m(2) for 5 weeks. Patients had to be naive to chemotherapy and radiotherapy. Patients were randomly assigned to receive either single doses of fosaprepitant 150 mg intravenously or placebo (saline) in combination with palonosetron 0·25 mg intravenously and dexamethasone 16 mg orally before cisplatin administration. Randomisation was done by the unmasked pharmacist, who used a list of six numbers (a block) provided in a sealed envelope. A web-based randomisation number generator was used to generate the full list of randomisation numbers that was split up in blocks of six numbers. All patients received oral dexamethasone 8 mg twice a day on day 2, 4 mg twice a day on day 3, and 4 mg once on day 4. The treatment was repeated for 5 weeks. The primary endpoint was the proportion of patients with sustained no emesis after 5 weeks of treatment. The modified intention-to-treat population (all patients who received study medication) was used for the statistical analyses. The study was registered with ClinicalTrials.gov, number NCT01074697.. Between June 15, 2010, and March 8, 2015, 246 patients from four countries consented to the study and were randomly assigned. Of these, 234 patients were eligible, having received study medication (118 received fosaprepitant, 116 received placebo). The proportion of patients with sustained no emesis at 5 weeks (competing risk analysis) was 48·7% (95% CI 25·2-72·2) for the placebo group compared with 65·7% (42·2-89·2) of patients for the fosaprepitant group. There was a significantly lower cumulative risk of emesis in the fosaprepitant group compared with the placebo group (subhazard ratio 0·58 [95% CI 0·39-0·87]; p=0·008). Treatments were generally well tolerated with few grade 3 adverse events none of which were related to the study treatment; the most common grade 3 adverse event during the 5 weeks of treatment was diarrhoea (11 [9%] of 118 patients in the fosaprepitant group vs six [5%] of 116 patients in the placebo group). There was only one report of a grade 4 adverse event (neutropenia), in the fosaprepitant group. No deaths were recorded in either group.. To our knowledge, this is the first study to investigate safety and efficacy of a NK-1 receptor antagonist during 5 weeks of radiotherapy and concomitant weekly cisplatin. Patients receiving fosaprepitant in addition to palonosetron and dexamethasone were less likely to experience emesis and nausea compared with those receiving palonosetron and dexamethasone alone. Both treatments were safe and well tolerated. Further investigations in other radiotherapy settings are warranted..

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.

Fosaprepitant, an intravenous neurokinin-1 receptor antagonist for chemotherapy-induced nausea and vomiting, contains polysorbate 80, which is associated with infusion-site adverse events (ISAEs) and hypersensitivity systemic reactions (HSRs). This study investigated ISAEs/HSRs following fosaprepitant with anthracycline-containing chemotherapy.. This retrospective chart review noted ISAEs/HSRs following the anthracycline doxorubicin+cyclophosphamide and a three-drug fosaprepitant regimen, via peripheral line.. 35/127 patients (28%) developed ISAEs/HSRs with chemotherapy and antiemetic therapy: 32 developed 137 individual ISAEs, primarily erythema, pain and catheter-site swelling; 16 developed 50 individual HSRs, primarily edema/swelling, erythema or dermatitis (no anaphylaxis).. Fosaprepitant is associated with a significant ISAE/HSR rate following anthracycline-containing chemotherapy via peripheral line. Polysorbate 80-free intravenous neurokinin-1 receptor antagonist may provide a safer chemotherapy-induced nausea and vomiting prophylaxis option.

Chemotherapy-induced nausea and vomiting (CINV) may occur during the acute (0-24 h) or delayed (25-120 h) phase following chemotherapy administration. The addition of a neurokinin 1 receptor antagonist to antiemetic regimens containing a 5-hydroxytryptamine type 3 receptor antagonist and dexamethasone has resulted in improved CINV prophylaxis. Due to numerous adverse events and hypersensitivity reactions associated with fosaprepitant, a commonly used neurokinin 1 receptor antagonist, there remains an unmet need for better-tolerated formulations. HTX-019, the US FDA-approved polysorbate 80- and synthetic surfactant-free aprepitant injectable emulsion, is bioequivalent to and better tolerated (fewer treatment-emergent adverse events) than fosaprepitant. HTX-019 represents a valuable alternative to fosaprepitant for CINV prophylaxis.
