NCT06385964
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.

* The goal of this clinical trial is to evaluate the performance, feasibility, and safety of emergency spacers compared to traditional spacers for the delivery of aerosolized drugs using pMDI. in young children and adult asthmatic patients The main questions it aims to answer are: 1. Measuring total emitted dose emitted from pMDI alone and attached to spacers. 2. Determining the pharmacokinetic parameter of aerosol delivered by different spacers. 3. Determining the lung bioavailability of aerosol delivered by different spacers. 4. Determining the systemic bioavailability of aerosol delivered by different spacers. 5. Determining the lung function after aerosol delivered by different spacers. 6. Determining the safety Researchers will compare salbutamol amount delivered using pMDI alone and pMDI connected to differents spacers to evaluate the performance, feasibility, and safety of emergency spacers compared to traditional spacers for the delivery of aerosolized drugs. Participants will asked to * inhale salbutamol through pMDI alone and pMDI connected to different spacers * perform lung function test using spirometer * urine samples will be taken from patients 30 minutes and 24 hours after dose inhalation. * use pulse oximeter to measure heart rate
