Trial ID or NCT#
Systemic sclerosis-associated pulmonary arterial hypertension (SSc-PAH) is a serious, life-threatening manifestation of systemic sclerosis (SSc), an autoimmune disease of the connective tissue characterized by scarring (fibrosis) and atrophy of the skin, joints and tendons, skeletal muscles, and internal organs, and immunological disturbances. One-year survival for patients with SSc-PAH ranges from 50-81%. There is currently no cure for SSc-PAH and treatment is limited to vasodilator therapy used in all forms of PAH. In recent studies, immunotherapy was shown to be effective in treating SSc-interstitial lung disease, another serious, life-threatening manifestation of SSc. In addition, there are compelling pre-clinical data and anecdotal clinical reports that suggest modulation of the immune system may be an effective strategy for treating SSc-PAH. To test this approach, this trial will determine if rituximab, an immunotherapy, has a marked beneficial effect on clinical disease progression, with minimal toxicity, in patients with SSc-PAH when compared to placebo.
