Brief Summary

This study was conducted in a randomized, double-blind, placebo-controlled design to evaluate the efficacy and safety of Genakumab injection in the treatment of CTD-ILD including Rheumatoid Arthritis associated Interstitial Lung Disease (RA-ILD) and Systemic Sclerosis associated Interstitial Lung Disease (SSc-ILD)

Conditions

Systemic Sclerosis Associated Interstitial Lung Disease; Rheumatoid Arthritis Associated Interstitial Lung Disease (RA-ILD); Systemic Sclerosis Associated Interstitial Lung Disease (SSc-ILD)

Keywords

connective tissue disease-associated interstitial lung disease; Rheumatoid Arthritis associated Interstitial Lung Disease (RA-ILD); Systemic Sclerosis associated Interstitial Lung Disease (SSc-ILD)

Outcome Measures

Primary Outcomes (4)

• Lung function assessment:Subjects' lung function was assessed by FVC .

  FVC will be evaluated simultaneously during the screening period, 4 weeks, 12 weeks, 24 weeks, 36 weeks, 48 weeks, and once every 24 weeks thereafter, From baseline up to 2 years

• Lung function assessment:Subjects' lung function was assessed by DLCO.

  DLCO will be evaluated simultaneously during the screening period, 4 weeks, 12 weeks, 24 weeks, 36 weeks, 48 weeks, and once every 24 weeks thereafter, From baseline up to 2 years，early withdrawal/termination of treatment, and when the investigator deems

• tLung function assessment:Visual simulation score was used to evaluate Physician's Global Asseessment（PGA）

  "Lung function assessment:The PGA is evaluated during the screening period and once every 12 weeks .From baseline up to 2 years.

• Safety evaluation indicator：Adverse Events

  From baseline up to approximately 2 years

EXPERIMENTAL

1\. Dosage: 300 mg.2. Duration of administration: All subjects received one dose of Genakumab injection every 4 weeks according to their group.The dose was injected subcutaneously.3. Course of administration: Phase I subjects were treated with Genakumab injection until the end of the study or the occurrence of the drug.Tolerable toxicity or investigator-assessed efficacy (whichever occurs first); The phase 2 randomized double-blind treatment period was 24 weeks, with a total of 6 administration times. After the randomized double-blind treatment period, an open-label treatment period was entered, and all subjects will receive Genakumab injection 300 mg Q4W until the end of the study or the occurrence of intolerable toxicity or poor efficacy assessed by the investigators (whichever occurs first).4. Administration method: subcutaneous injection; The injection site is the abdomen (3 cm away from the navel
