SC1011 Twice Daily vs Placebo in Patients Diagnosed With Idiopathic Pulmonary Fibrosis (IPF)
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to evaluate the efficacy and safety of Sufenidone (SC1011) in patients with IPF, and to provide a new safe and effective treatment option for patients with IPF. Participants will complete the study including screening period, treating period, and follow-up period. Investigators will compare the annual rate of decline in FVC to see if it is an optional new drug. The participants have lung function tests at study visits. The results of the lung function tests are compared between the SC1011 groups and the placebo group. The doctors also regularly check the general health of the participants.

Phase 2/Phase 3 |
Detailed Description
This is a randomized, double-blind, placebo-controlled study using a phase II/III adaptive seamless design. The study isdivided into three treatment groups: two active treatment groups and one placebo group. An interim analysis will be performed after the completion of 26 weeks of treatment in 75 patients. According to the safety and efficacy results analyzed, the appropriate active dose will be selected. Subjects will be divided into 3 treatment groups in a ratio of 1:1:1; After the interim analysis, if the DMC selected a treatment dose, all new recruits would be randomly assigned to the treatment and placebo groups in a 2:1 ratio. Subjects who were enrolled before the interim analysis will be adjusted to continue treatment at the selected dose up to 52 weeks.
This study includes screening period, treatment period and follow-up period. During the screening period, the subjects' lung imaging examinations performed at different centers required a central imaging diagnosis. The first dose after randomization is D1, and the treatment period for each subject is 52 weeks. All subjects will have a 4-week safety follow-up period after the end of treatment. Subjects who do not complete 52 weeks of treatment will also have a 4-week safety follow-up after the final dosing date.

Outcome Measures
Primary Outcome Measures
- Annual Rate of Decline in Forced Vital Capacity (FVC) Over 52 Weeks [Baseline and 52 weeks]
Forced vital capacity (FVC) is the total amount of air exhaled during the lung function test. For this endpoint reported means represent the adjusted rate.
Secondary Outcome Measures
- Change From Baseline in Saint-George's Respiratory Questionnaire (SGRQ) Total Score at 52 Weeks [Baseline and 52 weeks]
SGRQ is a health-related quality of life questionnaire divided into 3 components : symptoms, activity and impact.The total score (summed weights) can range from 0 to 100 with a lower score denoting a better health status. Means provided are the adjusted means based on all analyzed patients in the model (not only patients with a baseline and measurement at week 52)
- Time to First Acute Idiopathic Pulmonary Fibrosis (IPF) Exacerbation. [Week 52]
Due to rare events, the median of time to event is not calculable, thus the percentages of patients with (IPF) exacerbation are reported and represented as a key secondary endpoint.
