aprepitant and Headache

HTX-019 (CINVANTI. Study comprised Part A, a pilot Phase I, single-center, randomized, pharmacokinetic, safety and tolerability, open-label study, followed by Part B, a two-sequence crossover study of HTX-019 130 mg in healthy adults, via injection and infusion. Blood samples were evaluated for aprepitant pharmacokinetics and bioequivalence. Safety evaluations included treatment-emergent adverse events (TEAEs), vital signs, clinical laboratory testing and electrocardiograms.. In Part A, 24 subjects were randomly assigned to three cohorts (n = 8 per cohort) and received HTX-019 130 mg, administered intravenously over 15 min (cohort 1), 5 min (cohort 2) or 2 min (cohort 3). Progression to Part B occurred after acceptable tolerability was established in cohorts 2 and 3. In Part B, 50 randomized subjects received a 2-min injection (9 ml/min) and 30-min infusion (296 ml/h) of HTX-019 130 mg. Bioequivalence was demonstrated for HTX-019 injection and infusion. Both administration methods via a peripheral line were well tolerated; eight subjects experienced 11 TEAEs (six related) following injection and nine experienced 14 TEAEs (nine related) following infusion. Headache and fatigue were the most prevalent treatment-related TEAEs; one subject per group experienced feeling hot ≤30 min after drug administration.. Pharmacokinetic and tolerability profiles of 2-min HTX-019 injection support this potential alternative administration method for CINV prevention.

Chemotherapy-induced nausea and vomiting remain among the most feared adverse effects for cancer patients.. The aim of this study was to evaluate the efficacy and safety of a combination of aprepitant, palonosetron and dexamethasone as antiemetic prophylaxis in patients receiving multiple-day cisplatin-based chemotherapy.. Forty-one solid cancer patients received aprepitant, palonosetron and dexamethasone during a 3-day cisplatin-based chemotherapy. Primary end-point was complete response in the overall phase (day 1 until 5 days after the end of chemotherapy).. Aprepitant in combination with palonosetron and dexamethasone was safe, with hiccups (31.7%), fatigue (17.1%), headache (14.6%) and constipation (12.2%) the most common treatment-related adverse events, mostly mild. Complete response was seen in 58.5% of patients in the overall phase. In 23 patients receiving aprepitant in combination with palonosetron and dexamethasone more than one cycle (range: 2-5 cycles), the cumulative emetic protection rate after five cycles was 0.82.. This study shows aprepitant in combination with palonosetron and dexamethasone is safe and effectively controls chemotherapy-induced nausea and vomiting in patients undergoing 3-day cisplatin-based chemotherapy, moreover, the efficacy is maintained during multiple cycles.

Neurokinin-1 receptor (NK1R) antagonists have anti-HIV activity in monocyte-derived macrophages, decrease CCR5 expression and improve natural killer cell function ex vivo. Aprepitant is a NK1R antagonist approved by FDA as an antiemetic.. We conducted a phase IB randomized, placebo controlled, double masked study to evaluate the safety, antiviral activity, pharmacokinetics and immune-modulatory effects of aprepitant in HIV-infected adults not receiving antiretroviral therapy, with CD4+ cell count ≥350 cells/mm(3) and plasma viral load ≥2,000 copies/ml. Subjects were stratified by viral load (< vs. ≥20,000 copies/ml) and randomized within each stratum to receive aprepitant at 125 mg QD(Low), or 250 mg QD(High), or placebo(PL) for 14 days, and followed for 42 days.. Thirty subjects were randomized and 27 completed treatment (9, 8, 10 subjects in 125 (Low), 250 (High), and PL groups). 63% were male; 37% white; mean (SD) age 43 (9.3) years. Geometric mean baseline viral load (copies/ml) for Low, High, and PL was 15,709, 33,013, and 19,450, respectively. Mean (95%CI) change in log10 viral load at day 14 for Low, High, and PL was -0.02(-0.24,+0.20), -0.05(-0.21,+0.10), and +0.04(-0.08,+0.16), respectively. The number of subjects with AEs was 4(44.4%), 5(62.5%), and 1(10%) for Low, High, and PL. No Grade 4 AEs occurred.. Adverse events of aprepitant were more common in the treated groups. At the dose used in this two-week phase IB study, aprepitant showed biological activity, but no significant antiviral activity.. ClinicalTrials.gov NCT00428519.
