Brief Summary

Interstitial lung disease (ILD) is a heterogeneous group of diseases characterized by inflammation and/or fibrinization of the alveolar unit due to a variety of known or unknown causes. CTD-ILD is one of its common categories and includes any ILD with a definite diagnosis of connective tissue disease or with a set of symptoms, signs, and abnormalities suggested by laboratory examination. The incidence of CTD-ILD varies from home to abroad. Foreign studies indicate that the number of CTD-ILD in this study accounted for 34.8% of the total number of ILD in this study, while domestic studies indicate that the number of CTD-ILD in this study accounted for 67% of the total number of ILD. At present, the treatment of CTD-ILD includes hormone, immunosuppressant cyclophosphamide, mortemycophenate, tacrolimus, etc. The above treatment has great side effects, which may increase the risk of infection and the incidence of malignant tumor. Traditional Chinese medicine has unique advantages in alleviating the clinical symptoms of the disease, reducing the use of hormones and hormone complications, and preventing infection. Qifangfeixian granule is derived from "Fangji Huangqi Decoction" in the Summary of Golden Chamber. Modern pharmacology shows that Huangqi has the functions of regulating immunity, protecting liver, antibacterial and antiviral, etc. In order to further evaluate the effectiveness and safety of using Qifangfeixian granule (Huangqi, Fangji, dogwood, dodder, ginkgo, salvia miltiorrhizae, Taoren, etc.) in the treatment of CTD-ILD patients, Determined to explore a path of CTD-ILD treatment with Chinese characteristics, we hereby apply for a multicenter controlled clinical study.

Model Details: This is a randomized, placebo-controlled, multicenter study to evaluate the efficacy and safety of Qifangfeixian granules in the treatment of patients with fibrotic interstitial lung disease. The study drugs included Qi fangfeixian Granule and placebo, which was identical in appearance, taste and weight with Qifangfeixian Granule, and were given 1 bag twice a day. This study planned to enroll 124 subjects, who were randomly assigned at a ratio of 1:1, with 62 subjects in each group. Subjects who met all the inclusion criteria at baseline and did not meet the exclusion criteria were randomized to either of the following two groups: (1) Qifangfeixian Granule treatment group: oral administration of Qifangfeixian granule, 1 bag, 2 times a day; (2) Placebo (PRO) control group: oral administration of placebo, 1 bag, 2 times a day. Patients were evaluated after 12 weeks of treatment.
