Background: Nivolumab (Opdivo) is the first anti-PD-1 antibody approved in the world. LY01015 is a potential biosimilar of nivolumab.
Objectives: This phase I study aimed to establish the pharmacokinetic equivalence between LY01015 and the original investigational nivolumab (Opdivo) in healthy Chinese male subjects.
Introduction: We aimed to evaluate the safety, tolerability, pharmacokinetics, and immunogenicity of a single dose of LY-CovMab in Chinese healthy adults.
Methods: We conducted a phase 1, randomized, dose-escalation, placebo-controlled trial in 42 volunteers, 18-45 years of age, and 40 out of 42 received a single dose of LY-CovMab or placebo with LY-CovMab at a dose of 30 mg, 150 mg, 600 mg, 1200 mg, and 2400 mg. There were ten subjects in each group receiving LY-CovMab or placebo in a 4:1 ratio with the exception that the 30 mg group had two subjects both receiving LY-CovMab.
