A Study to Explore the Therapeutic Effect of HEC585 on Delaying Forced Vital Capacity (FVC) Decline and Tolerance in Progressive Fibrosing Interstitial Lung Disease (PF-ILD) Patients

Официальное название

A Phase IIb, Multi-center, Randomized, Double Blinded, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy and Safety of HEC585 Tablets in Patients With Progressive Fibrosing Interstitial Lung Disease

Обзор

The main goal of this phase llb study is to compare the efficacy and safety of two doses of HEC585 tablets with placebo which is a look-alike substance that contains no active drug in patients with progressive fibrosing interstitial lung diseases. This study is divided into two stages, i.e. main study stage with 24 weeks treatment duration followed by up to 96 weeks treatment extended study stage.

Вмешательства

• Препарат HEC585 dose A
  taking HEC585 dose A orally once daily, up to 24 weeks in main stage (if applicable); up to 96 weeks in extended stage
• Препарат HEC585 dose B
  taking HEC585 dose B orally once daily, up to 24 weeks in main stage; up to 96 weeks in extended stage
• Препарат Placebo
  taking Placebo orally once daily, up to 24 weeks in main stage
