About this study

This is a 2-Part study with Part A, a double-blind, randomized, placebo-controlled, PoC study to evaluate the efficacy, safety, and tolerability of efzofitimod in patients with SSc-ILD. The primary objective of the study is to evaluate the PoC for efficacy in a population with SSc-ILD. While improvement of ILD is the outcome of interest, the study will also evaluate changes in the skin. After initial screening (up to 4 weeks), approximately 25 eligible participants will be randomized 2:2:1 to 1 of 2 active (experimental) dose arms or placebo, administered every 4 weeks up to and including Week 20. Part B is an optional open-label extension to Part A in which participants can receive 450 mg efzofitimod every 4 weeks for 6 doses.
