December 13, 2023 updated by: Michael Roth

Scleroderma Lung Study III (SLS III): Combining the Anti-fibrotic Effects of Pirfenidone (PFD) With Mycophenolate (MMF) for Treating Scleroderma-related Interstitial Lung Disease

A Phase II multi-center, double-blind, parallel group, randomized and placebo-controlled clinical trial addressing the treatment of patients with active and symptomatic Scleroderma-related interstitial lung disease (SSc-ILD).

Study Overview

Detailed Description

A Phase II multi-center, double-blind, parallel group, randomized and placebo-controlled clinical trial addressing the treatment of patients with active and symptomatic Scleroderma-related interstitial lung disease (SSc-ILD). Patients who are either treatment naive or only recently started treatment (</= 6 months of prior treatment) will be randomized in a 1:1 assignment to receive either oral mycophenolate mofetil (MMF) and a placebo (Plac) or a combination of oral MMF and oral pirfenidone (PFD), with both regimens administered for 18 months. The primary hypothesis is that the rapid onset and anti-fibrotic effects of PFD, which have been observed in the treatment of Idiopathic Pulmonary Fibrosis (IPF), will complement the delayed antiinflammatory and immunosuppressive effects of MMF, to produce a significantly more rapid and/or greater improvement in lung function over time than occurs in patients receiving control therapy with MMF and Plac.

  18. Other serious concomitant medical illness (e.g., active malignancy within the past 5 years other than surgically-removed local skin cancer such as a basal cell carcinoma), chronic debilitating illness (other than SSc), unreliability or drug abuse that might compromise the patient's participation in the trial.
