Safety of antiemetic prophylaxis with HTX-019 as a 30-min infusion in patients with cancer: a retrospective study.

The NK-1 receptor antagonist HTX-019 (CINVANTI [aprepitant injectable emulsion]) was approved for preventing chemotherapy-induced nausea and vomiting based on bioequivalence studies in healthy volunteers. The objective of this study was to evaluate HTX-019 safety in cancer patients. This retrospective analysis evaluated the safety of HTX-019 130 mg 30-min intravenous infusion, as part of a three-drug antiemetic regimen. No treatment-emergent adverse events (TEAEs) were deemed related to HTX-019. During treatment cycles, three of 100 patients developed five reversible TEAEs: dyspnea, hot flash, pain, nausea and visual disturbance. Between cycles, six patients had TEAEs of dizziness (three patients), infusion-site events (two patients) and headache (two patients). HTX-019 is safe in cancer patients receiving chemotherapy.
