Intervention model description: Single-dose and multi-dose, dose escalation, placebo-controlled study
Primary purpose: TREATMENT

Brief summary: 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)

Detailed description: This is a first-in-human, randomized, double-blind, placebo-controlled clinical trial in healthy subjects. The trial consists of two parts: Part 1: a single ascending dose (SAD) study with seven dose groups: 2 mg (exploratory dose), 24 mg, 50 mg, 100 mg, 200 mg, and 300 mg, 400 mg (optional dose groups), with two subjects enrolled in the 2 mg group (all receiving the test drug), and eight subjects enrolled in each of the remaining groups (six test drug and two placebo); Part 2: a multiple ascending dose (MAD) study with seven dose groups: two subjects (six test drug and two placebo); and Part III: a randomized, double-blind, placebo-controlled clinical trial in healthy subjects, with a randomized, double-blind, placebo-controlled clinical trial in healthy subjects. Part II: Multiple ascending dose (MAD) study, divided into 3 dose groups: 100 mg, 200 mg and 300 mg, each including 8 healthy subjects (6 test drug, 2 placebo).
