Overview

This study is to evaluate the clinical efficacy and safety of Jin-shui Huan-xian Formula in retarding the decline of pulmonary function in IPF, generate high - quality clinical evidence, and establish a treatment plan of Jin-shui Huan-xian Formula for retarding the decline of pulmonary function in Idiopathic Pulmonary Fibrosis（IPF）

The study took 384 IPF patients as the research objects and adopted a randomized, double - blind, placebo - controlled trial design. The patients were randomly divided into an experimental group and a control group. On the basis of guideline - guided treatment, the experimental group was given Jin-shui Huan-xian Formula, and the control group was given a placebo of Jin-shui Huan-xian Formula. The treatment lasted for 52 weeks. Pulmonary function (FVC) was set as the primary outcome indicator, and acute exacerbation, pulmonary function (DLCO, DLCO%, etc.), exercise endurance, quality of life, etc. were set as secondary outcome indicators. Blood routine, urine routine, liver function, renal function, electrocardiogram, etc. were set as safety indicators. The clinical efficacy and safety of Jin-shui Huan-xian Formula in retarding the decline of pulmonary function in IPF were evaluated to generate high - quality clinical evidence and establish a treatment plan of Jin-shui Huan-xian Formula for retarding the decline of pulmonary function in IPF.
