A Double-blinded, Placebo-controlled Pilot Study of Dimethyl Fumarate (DMF) in Pulmonary Arterial Hypertension (PAH) Associated With Systemic Sclerosis (SSc-PAH): The Effect of DMF on Clinical Disease and Biomarkers of Oxidative Stress.

A double-blinded, placebo-controlled study of Dimethyl fumarate (DMF) in 34 Systemic
Sclerosis-Pulmonary Hypertension (SSc‐PAH) patients. The study will determine safety and the
primary outcome variability for DMF in treating SSc‐PAH; the primary outcome of clinical
efficacy in this pilot trial will be improvement in 6‐minute walk distance (6MWD).

A double-blinded, placebo-controlled study of Dimethyl fumarate (DMF) in 34 Systemic
Sclerosis-Pulmonary Hypertension (SSc‐PAH) patients. The study medication will be added to
stable background PAH medication(s). Subjects will be dosed for 24 weeks, will undergo
examination every 8 weeks, and will be finally evaluated 12 weeks after completion of
treatment. Dosage will be twice daily oral doses of 120mg for the first 7 days followed by
the maintenance dose of 240mg twice a day.Participation will be for a total of 40 weeks,
including a 4-week screening period, 24 weeks of drug, and a safety follow‐up 12 weeks after
the last dose. The study will determine the safety and the primary outcome variability for
DMF in treating SSc‐PAH; the primary outcome of clinical efficacy in this pilot trial will be
improvement in 6‐minute walk distance (6MWD).
