简要总结

This study is a multicenter, randomized, double-blind, placebo-controlled Phase II clinical trial designed to evaluate the efficacy and safety of RSS0343 tablets in patients with COPD. The study includes 3 study periods: a 4-week screening period, a 48-week treatment period, and a 4-week follow-up period. The primary endpoint is the annualized rate of moderate or severe exacerbations of COPD during the 48-week treatment period.

入选标准

  • Voluntarily sign a written informed consent form.
  • Aged 40 to 80 years, male or female.
  • Body mass index (BMI) ≥18 kg/m².
  • Diagnosed with chronic obstructive pulmonary disease (COPD) as defined by the Chinese Guidelines for the Diagnosis and Management of COPD (2021 Revised Edition), with a documented COPD history of ≥12 months prior to screening.
  • Post-bronchodilator FEV₁/FVC \<0.7 at the screening period; and post-bronchodilator FEV₁/FVC \<0.7 with FEV₁% predicted ≥20% at baseline.
  • Documented history of at least ≥1 moderate or severe acute exacerbation of COPD (AECOPD) within 12 months prior to screening.
  • On stable doses of triple therapy or dual therapy for COPD maintenance treatment for ≥3 months prior to screening.
  • COPD Assessment Test (CAT) score ≥10 at screening and randomization.
  • Current or former smoking history of ≥10 pack-years at screening.
  • Male and female subjects of childbearing potential and their partners must have no plans for conception or sperm/ova donation for 6 months (female subjects) or 3 months (male subjects) after the last dose and must voluntarily use effective contraception. Female subjects of childbearing potential must have a negative pregnancy test during screening and prior to the first dose and must not be lactating.

排除标准

  • Subjects with systemic immunosuppressants, biologic agents, or Th2 cytokine inhibitors within 12 weeks prior to randomization or within 5 half-lives of the drug, whichever is longer.
  • Subjects with medications known to potentially cause skin hyperkeratosis within 4 weeks prior to screening.
  • Subjects with the followings within 4 weeks prior to randomization: systemic corticosteroids, phosphodiesterase inhibitors, xanthine derivatives, leukotriene receptor antagonists, bacterial lysates, antitussive/expectorant medications, infusion of blood products or immunoglobulins.
  • Subjects with strong CYP3A inducers or inhibitors within 14 days or 5 half-lives (whichever is longer) prior to randomization.
  • Administration of live, attenuated live, or viral vector vaccines within 4 weeks prior to randomization.
  • Participation in another clinical trial involving an investigational product with active ingredients within 3 months prior to screening, or still within 5 half-lives of the investigational product at screening.
  • Prior treatment with RSS0343 tablets or treatment with products targeting the same mechanism of action within 3 months prior to screening.
  • Lung surgery or lung volume reduction surgery within 1 year prior to screening; or interventional procedures for chronic bronchitis within 1 year prior to screening.
  • Requirement for supplemental oxygen therapy for ≥15 hours per day or mechanical ventilation; or clinically significant sleep apnea requiring the use of a continuous positive airway pressure (CPAP) device or non-invasive positive pressure ventilation (NIPPV) device.
  • Presence of a moderate or severe acute exacerbation of COPD (AECOPD) from 4 weeks prior to screening up to randomization.
