Idera (IDRA) Initiates TLR Inhibitor IMO-3100 Phase 2

April 17, 2012 8:26 AM EDT
Idera Pharmaceuticals, Inc. (NASDAQ: IDRA) today announced the treatment of the first patient in a Phase 2 clinical trial of IMO-3100, the Company’s lead Toll-like receptor (TLR) inhibitor for the treatment of autoimmune diseases, in patients with moderate to severe plaque psoriasis.

The Phase 2 trial is a randomized, double-blind, and placebo-controlled study of IMO-3100 in patients with psoriasis. The trial is designed to evaluate the safety and markers of efficacy of IMO-3100 as a monotherapy. In the study, 45 patients with moderate to severe plaque psoriasis will receive IMO-3100 at 0.16 or 0.32 mg/kg or placebo (saline) by subcutaneous injection once weekly for four weeks. Assessments of safety will be performed throughout the treatment and follow-up periods. Psoriasis intensity will be monitored throughout the study. Skin biopsies of an active psoriasis plaque will be obtained prior to treatment and one week after the last treatment, and will be analyzed by immunohistologic staining for changes in epidermal thickness, immune cell infiltrates and cytokine expression. This trial is being conducted at multiple sites in the United States, and skin biopsies will be analyzed at a central laboratory.
