Brief Summary:
This is a Phase 1 single and multiple dose escalation study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of PF-06835375 in subjects with seropositive SLE or RA. The design is double-blind, sponsor open and placebo controlled. This study will include two parts: Part A and Part B. Part A will consist of single ascending dose cohorts, Part B of multiple ascending dose cohorts. This study will enroll up to a total of approximately 112 subjects at approximately 10 sites.
