Bioequivalence of netupitant and palonosetron (NEPA) oral suspension and hard capsules in healthy individuals: results from an open-label, randomized, two-treatment, four-period, two-sequence replicative design trial.

ABSTRACT:

Purpose

NEPA, a fixed-antiemetic combination of netupitant and palonosetron, is available via two administration routes (oral and intravenous). A new oral suspension was developed to offer a more convenient option for patients. This study evaluated the bioequivalence between the oral capsule and the oral suspension.

Methods

Open-label, randomized, single-center phase I trial conducted according to a two-treatment, four-period, two-sequence replicative design. Two treatments were investigated for bioequivalence: a 10-mL oral suspension (Test [T]) and the hard capsule (Reference [R]), both containing 300 mg netupitant/0.5 mg palonosetron. Healthy individuals were randomized (1:1) to receive two doses of both Test and Reference formulations, in either T-R-T-R or R-T-R-T sequenc
