SEATTLE, Jan. 11 /PRNewswire-FirstCall/ -- Trubion Pharmaceuticals, Inc. today announced that its collaboration partner, Pfizer, has initiated a Phase 2 clinical trial of SBI-087 (PF-05230895) for the treatment of rheumatoid arthritis (RA). SBI-087 is a next-generation, humanized Small Modular ImmunoPharmaceutical (SMIP(TM)) protein therapeutic directed against the CD20 antigen. SBI-087 is also being evaluated in Phase 1 clinical trials for RA and systemic lupus erythematosus (SLE).
The Phase 2 multi-center, randomized, placebo-controlled, double-blind, parallel-group, outpatient dose regimen-finding study will enroll approximately 200 patients who meet the criteria for RA with American College of Rheumatology (ACR) Functional class I, II or III, are seropositive, and who have been diagnosed with RA more than six months before trial initiation. Participants will be randomly assigned to receive either placebo or one of four SBI-087 dosing regimens. This study is designed to evaluate the safety and efficacy of a dose and dosage regimen of SBI-087 in seropositive patients with active RA, who are on a stable dose of methotrexate. The primary outcome measure will include responses based on the ACR criteria (ACR 20 response).
