The primary safety endpoint was the incidence of serious adverse events and all adverse events in dimethyl fumarate compared to placebo-treated patients. The primary efficacy endpoint was the change in 6-min walk distance from baseline to the end of treatment at Week 24 in dimethyl fumarate compared to placebo-treated patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Six participants were randomized to either placebo (n\u2009=\u20092) or dimethyl fumarate (n\u2009=\u20094). Baseline demographics were similar in both groups. A total of 25 adverse events occurred in 6 subjects, with 14 adverse events (56.0%) having occurred in dimethyl fumarate-treated subjects. Three occurrences were identified as nausea adverse events, and two participants withdrew due to nausea. One participant in the placebo group was withdrawn after a hospitalization serious adverse event due to worsening of heart failure and shortness of breath secondary to anemia. One participant in each group completed protocol. Subjects in the dimethyl fumarate-treated group showed a non-significant reduced decline in 6-min walk distance (relative mean change of \u22127.07%) from baseline to Week 24 as compared to placebo-treated subjects (relative mean change of \u221214.97%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Patients treated for pulmonary arterial hypertension\u2013associated systemic sclerosis with 2- and 3-drug regimens, as is now typical for these patients, tolerate dimethyl fumarate poorly.
