Brief summary: The primary objective of this randomized, double-blind, single/multiple ascending dose, placebo-controlled Phase I clinical trial was to evaluate the safety and tolerability of SHR-4597 in healthy subjects and asthmatic patients. The study consists of two parts: Part 1 involves single ascending inhalation dose in healthy subjects; Part 2 involves multiple ascending inhalation dose in asthmatic patients, further divided into Part 2A: multiple ascending inhalation dose in mild to moderate asthmatic patients, and Part 2B: multiple ascending inhalation dose in moderate to severe asthmatic patients. Subsequent lung pharmacokinetic studies of SHR-4597 inhalation will be conducted based on patients' PKPD data.
