Comparative Bioequivalence Study of 2 Clevidipine Formulations in Healthy Chinese participants: A Single‐Dose, 2‐Period Crossover Trial

Clevidipine emulsion is an intravenous antihypertensive agent indicated for acute blood pressure control when oral therapies are contraindicated or ineffective. To address this gap in availability, a randomized, 2-period, 2-sequence crossover trial was conducted to evaluate the bioequivalence and safety of a generic clevidipine emulsion versus the reference product in 32 healthy Chinese adults. Participants received a 30-minute intravenous infusion of 3 mg of clevidipine (test or reference formulation) in each study period, with serial blood samples collected from the contralateral arm relative to the infusion site for pharmacokinetic analysis. Treatment-emergent adverse events (TEAEs) were monitored throughout the study. All participants completed both treatment phases. The generic formulation satisfied bioequivalence criteria for all primary pharmacokinetic parameters, with geometric mean ratios (90% confidence intervals) of C_max, AUC_0-t, and AUC_0-∞ fully contained within the 80%-125% equivalence range. Three participants (9.4%) experienced mild TEAEs assessed as treatment-related, including transient sinus tachycardia (n = 2) and asymptomatic alanine aminotransferase elevation (n = 1). The generic formulation met bioequivalence criteria and exhibited comparable safety profiles to the reference product.
