What this trial studies

This clinical trial is a randomized, double-blind study that compares the efficacy and safety of Sufenidone (SC1011) against a placebo in patients diagnosed with Idiopathic Pulmonary Fibrosis (IPF). Participants will undergo screening, treatment, and follow-up assessments, with a focus on measuring forced vital capacity (FVC) decline and overall health checks. The study includes an interim analysis at 26 weeks to determine the optimal dose for a 52-week treatment period, followed by a 4-week safety monitoring phase.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with Idiopathic Pulmonary Fibrosis within the last 5 years, with specific lung function criteria.

Not a fit: Patients with a known cause of interstitial lung disease or those on a lung transplant waiting list may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients suffering from Idiopathic Pulmonary Fibrosis.

How similar studies have performed: Other studies have explored treatments for Idiopathic Pulmonary Fibrosis, but the specific approach of using Sufenidone is novel.
