A Phase 2 Dose Ranging Study to Evaluate the Efficacy and Safety of AMG 570 in Subjects With Active Systemic Lupus Erythematosus (SLE) With Inadequate Response to Standard of Care (SOC) Therapy

IRB Number: 2020-0197
not enrolling new patients

Institutional Review Board, Hospital for Special Surgery

The safety of our participants is our top priority. The trial/study is approved and periodically reviewed by the Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.

Before enrolling in a clinical trial or research study, the investigator will explain the purpose of the trial/study, its expected benefits, any possible risks or side effects, and what your role will be. If you want to join the trial/study, you must sign informed consent documents. You can leave a trial/study at any time without penalty.

The purpose of this study is to evaluate safe and efficacious doses of AMG 570 for active Systemic Lupus Erythematosus (SLE) in patients who are not responding to the current standard of care. AMG 570 is an antibody designed to bind to both ICOSL and BAFF, two molecules involved in the immune response. Preliminary nonclinical studies have shown that there is potential for the dual-target treatment with AMG 570 to be a successful treatment for autoantibody associated diseases such as SLE. AMG 570 could be a viable treatment option for patients with active SLE who are not responding to current standard of care. 
Approximately 300 patients will be enrolled into this study worldwide, about 2 of which will be at Hospital for Special Surgery. Study subjects who meet the study requirements and are enrolled will be randomized to receive either placebo or 1 of 3 dosages of AMG 570 with the last dose at week 50. Treatment will be administered every 2 weeks subcutaneously. Study duration for a single subject will be 52 weeks plus a screening period and a 16-week safety follow-up period. The research staff will provide a schedule of assessments that illustrates when study subjects will be expected to attend study visits.
