Primary Outcome Measures:
  • The safety and tolerability of MEDI-551 will be assessed primarily by summarizing treatment-emergent AEs and SAEs. [ Time Frame: Day 85 ]

Secondary Outcome Measures:
  • The secondary endpoints of the study are to assess the PK, IM, and PD of single IV doses of MEDI-551 in adult subjects with scleroderma. Pharmacodynamics will be assessed by numbers of B cells in blood and skin. [ Time Frame: Day 85 ]

  • Concurrent enrollment in another clinical study with the exception of observational or interventional studies that do not involve therapeutic strategies or invasive diagnostic tests
