About

This is a first-in-human, randomized, double-blind, placebo-controlled trial in healthy subjects. The trial consisted of two parts: part 1: single ascending dose (SAD) study and part 2: multiple ascending dose (MAD) study. Each part had multiple Intravenous infusion administration dose groups. Prior to the formal initiation of the dose-escalation trial, the safety, tolerability, and pharmacokinetics (PK) characteristics of a pretest dose (pilot dose) of 2 mg will be evaluated in 2 subjects (both administered BG136 for injection)

Full description

This is a first-in-human, randomized, double-blind, placebo-controlled clinical trial in healthy subjects.
