ABSTRACT
Background:
NEPA, an oral fixed combination of the NK1RA netupitant (300 mg) and clinically/pharmacologically distinct 5-HT3RA palonosetron (PALO, 0.50 mg), is the first fixed antiemetic combination to have been approved. A single oral NEPA capsule plus dexamethasone (DEX) given before anthracycline-cyclophosphamide (AC) and non-AC highly emetogenic chemotherapy (HEC) showed superior prevention of chemotherapy-induced nausea and vomiting (CINV) over PALO plus DEX for 5 days postchemotherapy. The safety of NEPA was well-established in the phase II/III clinical program in 1169 NEPA-treated patients. An intravenous (i.v.) formulation of the NEPA combination (fosnetupitant 235 mg plus PALO 0.25 mg) has been developed. Patients andmethods:
This randomized, multinational, double-blind, stratified (by sex and country) phase III study (NCT02517021) in chemotherapy-naïve patients with solid tumors assessed the safety of a single dose of i.v. NEPA infused over 30 min before initial and repeated cycles of HEC. Patients received either i.v. NEPA or oral NEPA, both with oral DEX on days 1-4. Safety was assessed primarily by treatment-emergent adverse events (AEs) and electrocardiograms.Results:
A total of 404 patients completed 1312 cycles. The incidence and type of treatment-emergent AEs were similar for both treatment groups with the majority of AEs as mild/moderate in intensity. There was no increased incidence of AEs in subsequent cycles in either group. The incidence of treatment-related AEs was similar and relatively low in both groups (12.8% i.v. NEPA and 11.4% oral NEPA during the entire study), with constipation being the most common (6.4% i.v. NEPA, 6.0% oral NEPA). No serious treatment-related AEs occurred in either group. No infusion site or anaphylactic reactions related to i.v. NEPA occurred. No clinically relevant changes in QTc and no cardiac safety concerns were observed.Conclusions:
Intravenous NEPA was well-tolerated with a similar safety profile to oral NEPA in patients with various solid tumors receiving HEC.
