CAMBRIDGE, Mass. and EXTON, Pa., Nov. 05, 2015 (GLOBE NEWSWIRE) -- Idera Pharmaceuticals, Inc. (NASDAQ:IDRA), a clinical-stage biopharmaceutical company developing toll-like receptor and RNA therapeutics for patients with cancer and rare diseases, today announced that new data from the Phase 1/2 clinical trial for IMO-8400, a TLR 7,8 and 9 antagonist, being evaluated for the treatment of relapsed, refractory patients suffering from Waldenström’s Macroglobulinemia, will be presented at the 2015 American Society of Hematology (ASH) Annual Meeting in Orlando, FL, December 5-8, 2015.

The open-label, dose-ranging clinical trial included three dose-escalating cohorts on IMO-8400 and enrolled 19 patients, who were relapsed or refractory to prior therapies. Data from these 19 patients will be presented at the ASH Meeting.
