Official title

A Multicenter, Randomized, Double-blind, Placebo-controlled Phase II Clinical Trial to Evaluate the Efficacy and Safety of HRS-9821 Inhalation Suspension in Patients With Moderate to Severe Chronic Obstructive Pulmonary Disease

Overview

The study is being conducted to evaluate the efficacy and safety of HRS-9821 for patients with COPD, and to explore the reasonable dosage of HRS-9821 for patients with COPD.

Interventions

  • Drug HRS-9821 Inhalation Suspension
    HRS-9821 Inhalation Suspension.
  • Drug HRS-9821 Placebo Inhalation Suspension
    HRS-9821 Placebo Inhalation Suspension.

Primary outcome measures

  • Changes in peak FEV1 (forced expiratory volume in one second) after 28 days of treatment. [Time frame: From baseline to 28 days after treatment.]
Secondary outcome measures (6)
  • Changes in FEV1 area under the curve versus time from 0 to 12 hours (AUC0-12h) and 0 to 4 hours (AUC0-4h) after 1, 14 and 28 days of treatment. [Time frame: During 28 days of treatment.]
  • Changes in peak FEV1 after 1 and 14 days of treatment. [Time frame: After 1 and 14 days of treatment.]
  • Changes in trough FEV1 after 1, 14 and 28 days of treatment. [Time frame: After 1, 14 and 28 days of treatment.]
  • Changes in FVC (forced vital capacity) during 28 days of treatment. [Time frame: During 28 days of treatment.]
  • Changes of in SGRQ (St. George's Respiratory Questionnaire), CAT (COPD Assessment Test), mMRC (modified Medical Research Council） score during 28 days of treatment. [Time frame: During 28 days of treatment.]
  • The use of SABA (Short-Acting Beta₂ Agonist) during 28 days of treatment. [Time frame: During 28 days of treatment.]
