EXTON, Pa., May 09, 2018 (GLOBE NEWSWIRE) — Idera Pharmaceuticals, Inc. (“Idera”) (NASDAQ:IDRA), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of novel nucleic acid-based therapeutics for oncology and rare diseases, today reported its financial and operational results for the first quarter ended March 31, 2018.

“Our company continues to make significant progress advancing our two lead TLR modulating clinical development candidates, tilsotolimod and IMO-8400,” stated Vincent Milano, Idera’s chief executive officer.  Milano continued, “As we now advance through the second quarter, we are continuing to enroll patients in the ILLUMINATE oncology trials, with the next planned data from ILLUMINATE-204 in PD-1 refractory metastatic melanoma to be presented at the American Society of Clinical Oncology (“ASCO”) Annual Meeting and completion of enrollment expected by year end.  For IMO-8400, we plan to report top-line data from our Phase 2 trial in dermatomyositis in June.  As it pertains to our nucleic acid chemistry research group, we completed our data analysis for IDRA-008 which has led us to a decision to not advance that program into the clinic.”

“In January of this year, we announced our proposed merger with BioCryst Pharmaceuticals, Inc. that we believe will build greater and more sustainable value for the benefit of stockholders as well as patients with rare diseases beyond what we could achieve alone. The Idera Board determined this combination was compelling from both a strategic and financial perspective following a careful evaluation of a range of strategies to enhance long-term stockholder value. The transaction will create a leading rare disease company with a robust pipeline including two promising Phase 3 rare disease programs and combines synergistic discovery engines that will not only expand the number of rare diseases we can target but create meaningful opportunities for differentiation in the market through joint small molecule and oligo treatments. Importantly, joining with BioCryst will also enable us to achieve cost synergies and increase our financial strength and flexibility.  Subject to shareholder approval, we expect to close the transaction in the third quarter,” Milano expressed.

(IMO-8400) Development Activities

PIONEER-211 – Randomized placebo controlled Phase 2 trial of IMO-8400 in adult patients with dermatomyositis:

• Enrollment concluded during Q3 2017 (30 patients); and
• Topline phase 2 trial data expected in June 2018.

Nucleic Acid Chemistry Research Group

• We are developing our nucleic acid chemistry technology to “turn off” the mRNA associated with disease causing genes. Our focus is on creating candidates targeted to specific genes to treat cancer and rare diseases.
• We had selected IDRA-008 as our first nucleic acid chemistry research program candidate. IDRA-008 targets the Apolipoprotein C-III (APOC-III) gene and was being developed for the treatment of Familial Chylomicronemia Syndrome (FCS) and Familial Partial Lipodystrophy (FPL) which had available pre-clinical animal models and well-known clinical endpoints.
• During the first quarter of 2018, we completed our pre-clinical analysis for IDRA-008 and based upon the outcome of pre-clinical pharmacology studies, including a comparative pharmacology study with the competitive development asset volanesorsen, and IND-enabling safety evaluation, we made a data-driven decision to not advance IDRA-008 into clinical development. 
• We are currently conducting analysis throughout our research portfolio to identify other candidates for future clinical development based on our nucleic acid technology expertise and potential strategic commercial opportunity.

While the list of factors presented here is, and the list of factors presented in the Registration Statement is, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on BioCryst’s or Idera’s consolidated financial condition, results of operations, credit rating or liquidity. Readers are urged to consider these factors carefully in evaluating these forward-looking statements, and not to place undue reliance on any forward-looking statements.

The forward-looking statements in this document speak only as of the date of this document. Except as required by law, Idera and BioCryst assume no obligation to update or revise these forward-looking statements for any reason, even if new information becomes available in the future.
