Brief Summary:
This is a prospective open-label trial that will enroll 12 patients with systemic sclerosis (SSc) and at least one calcinotic lesion of the hands that is palpable on physical examination and also measureable on hand radiographs, at one single center. Each subject will receive treprostinil orally for 12 months, and follow-up evaluations will be performed every 3 months. Our main objective is to determine whether oral treprostinil is safe, and effective in reducing calcinosis in patients with SSc. We hypothesize that calcinosis is a result of microvascular injury and ischemic damage, and that therefore treprostinil may be beneficial in the treatment of calcinosis in patients with SSc.

Primary Outcome Measures :
  1. To assess the number of participants with treatment-related adverse events following treatment with oral treprostinil [ Time Frame: 12 months ]
  2. To determine the mean rate of change of calcinosis in radiograph following treatment with oral treprostinil as assessed by a novel radiographic scoring system [ Time Frame: 12 months ]

Secondary Outcome Measures :
  1. To assess the effect of oral treprostinil on the change in Scleroderma Health Assessment Questionnaire (SHAQ) [ Time Frame: 12 months ]
  2. To assess the effect of oral treprostinil on the change in Cochin Hand Functional Scale [ Time Frame: 12 months ]
  3. To assess the effect of oral treprostinil on the change in SF-36 [ Time Frame: 12 months ]
  4. To assess the effect of oral treprostinil on the change in Mawdsley Calcinosis Questionnaire [ Time Frame: 12 months ]
  5. To assess the effect of oral treprostinil on the change in Raynaud Condition Score [ Time Frame: 12 months ]
  6. To assess the effect of oral treprostinil on the change in patient global assessment of calcinosis severity [ Time Frame: 12 months ]
  7. To assess the effect of oral treprostinil on the change in physician global assessment of calcinosis severity [ Time Frame: 12 months ]
  8. To assess changes in blood flow using SPY perfusion machine following treatment with treprostinil at 1 year compared to baseline. [ Time Frame: 12 months ]
  9. To assess the number of patients with changes in vascular and SSc-PAH associated biomarkers following treatment with treprostinil at 1 year compared to baseline [ Time Frame: 12 months ]

  • If female of childbearing potential, the patient must have a negative pregnancy test at screening and baseline visits
  • Oral corticosteroids (≤ 10 mg/day of prednisone or equivalent) and NSAIDs are permitted if the patient is on a stable dose regimen for ≥ 2 weeks prior to screening and throughout the study
  • Calcium channel blockers, alpha-1-antagonists, ACE-inhibitors, angiotensin receptor blockers, and protein-pump inhibitors are permitted as long as the doses are stable for 4 weeks prior to screening and throughout the study
  • Women of childbearing potential must agree to use adequate contraception when sexually active with any combination of at least 2 effective methods of birth control (except for women who have a partner who is sterile, i.e. due to vasectomy)

Exclusion Criteria:

  • Patients receiving bisphosphonates, warfarin, colchicine, minocycline, intravenous immunoglobulins, or biological agents including abatacept or rituximab within 4 weeks of screening
  • Patients receiving local treatments for calcinosis including surgical removal or intralesional steroid injections within 12 weeks of screening or throughout the study.
  • Patients who have participated in another clinical trial of an investigative agent within 30 days of screening (or 5 half-lives of the investigational drug, whichever is longer)
  • Pregnant or nursing women
  • Patients with a history of drug or alcohol abuse within 6 months of screening
  • Any medical condition that, in the opinion of the investigator, might interfere with the subject's participation in the study or poses an added risk for the subject
