Anthera Announces the Phase 2b PEARL-SC Data Has Been Accepted as a Late Breaking Poster Presentation at the ACR/ARHP 2012 Annual Scientific Meeting

HAYWARD, Calif., Nov. 1, 2012 /PRNewswire/ -- Anthera Pharmaceuticals, Inc. (Nasdaq: ANTH), a biopharmaceutical company developing drugs to treat serious diseases associated with inflammation and autoimmune disorders, today announced that an abstract of the results from the Phase 2b PEARL-SC clinical study examining the treatment effect of blisibimod in systemic lupus erythematosus patients has been accepted as a late-breaking poster presentation at the 2012 Annual Scientific Meeting of the American College of Rheumatology and the Association of Rheumatology Health Professionals (ACR/ARHP).

"We are pleased to have this opportunity to share the PEARLS-SC responder analyses and sub-population results with the rheumatology community," said Colin Hislop, MD, Anthera's Senior Vice President and Chief Medical Officer. "In PEARL-SC, blisibimod demonstrated a clinically meaningful treatment effect in patients with severe disease who continued to have active lupus despite corticosteroid use. This highlights blisibimod's potential to help patients with more active and severe disease as we move forward with our Phase 3 clinical trials."

The poster entitled, "Blisibimod, an Inhibitor of B Cell Activating Factor, in Patients with Moderate-to-Severe Systemic Lupus Erythematosus," is scheduled to be presented by Dr. Richard Furie on Tuesday, November 13, from 9 am11 am Eastern Time (Presentation Number L6).

The abstract is available online through the ACR website at www.rheumatology.org. In accordance with the conference's embargo policy, the poster will be uploaded to the Anthera website only after completion of the session.

About Blisibimod and PEARL-SC
BAFF has been associated with a wide range of B-cell-mediated autoimmune diseases, including systemic lupus erythematosus, vasculitis, IgA nephropathy, immune thrombocytopenic purpura and others. Multiple clinical studies with other BAFF antagonists recently have reported on BAFF's potential positive role in treating lupus and rheumatoid arthritis. Anthera is advancing its development of blisibimod, a broad inhibitor of BAFF, to expand its potential clinical utility in autoimmune diseases. Blisibimod is a novel fusion protein called a peptibody and is distinct from an antibody. Anthera owns worldwide rights to blisibimod in all potential indications.  The PEARL-SC Phase 2 study was designed as a randomized, double-blind, placebo-controlled, dose-ranging superiority trial to evaluate the safety, tolerability and efficacy of blisibimod plus standard of care, versus placebo plus standard of care.  A total of 547 patients with active SLE were randomized to receive one of three different doses of blisibimod or placebo (100 mg weekly, 200 mg weekly or 200 mg monthly) administered subcutaneously over a minimum 24-week treatment period, in addition to standard-of-care therapy. The study was conducted at multiple centers worldwide.
