| Safety and Tolerability Study Of PF-06835375 In Subjects With Seropositive Systemic Lupus Erythematosus Or Rheumatoid Arthritis |
| A PHASE 1, RANDOMIZED, MULTI-CENTER, DOUBLE-BLIND, SPONSOR OPEN, PLACEBO-CONTROLLED, SINGLE AND MULTIPLE DOSE-ESCALATION STUDY TO EVALUATE THE SAFETY, TOLERABILITY, PHARMACOKINETICS AND PHARMACODYNAMICS OF PF-06835375 IN SUBJECTS WITH SEROPOSITIVE SYSTEMIC LUPUS ERYTHEMATOSUS OR RHEUMATOID ARTHRITIS |
| 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. |
