Full Study Name

A Multicenter, Double-Blind, Randomized, Placebo-Controlled, Phase III Study Evaluating the Safety and Efficacy of Intravenous Iloprost in Subjects With Systemic Sclerosis Experiencing Symptomatic Digital Ischemic Episodes (IRB no. 00000961)


This study focuses on individuals who have been diagnosed with systemic sclerosis (SSc) and are experiencing symptomatic digital ischemic episodes. Digital ischemic episodes are the most common indicator of vascular abnormalities in SSc. Most people with SSc also have symptomatic Raynaud’s phenomenon (RP) attacks, which are caused by blood vessels in the hands and fingers that overreact to cold temperatures or stress and can result in pain, numbness, tingling, discomfort, and discoloration of the fingers.
The purpose of this study is to evaluate the investigational use of a drug called iloprost for the treatment of symptomatic RP attacks in people with SSc. Participants will be randomly assigned to receive either iloprost or placebo (inactive substance). Researchers will evaluate the safety and tolerability of iloprost and aim to determine whether the drug has an effect on how often symptomatic RP attacks occur. Additionally, the study will examine participants’ overall improvement in symptomatic RP attacks, as well as assess overall benefits compared to side effects.
