Phase III Clinical Trial of Telitacicept Injection in the Treatment of Patients With Connective Tissue Disease-related Interstitial Lung Disease Phase 3 260
The main purpose of this study is to evaluate the efficacy of telitacicept compared with placebo in slowing down the decline in lung volume in patients with interstitial lung disease associated with connective tissue disease (CTD-ILD) on the basis of standard treatment.
Phase III Clinical Trial of Telitacicept Injection in the Treatment of Patients With Connective Tissue Disease-related Interstitial Lung Disease
- RC18-C309
| Participant Group/Arm | Intervention/Treatment |
|---|---|
ExperimentalTelitacicept Participants will receive elitacicept in addition to standard therapy. | Telitacicept Subjects will receive 160 mg. The study drug is administered once weekly (QW). |
Placebo ComparatorPlacebo Participants will receive placebo in addition to standard therapy. | Placebo The placebo contains no active ingredients. To maintain the blind, the placebo matches the active drug in all physical aspects. The placebo is administered once weekly (QW). |
