Idera Pharmaceuticals Provides 2020 Update and Outlook
Company to Present at the 38th Annual J.P. Morgan Healthcare Conference on Thursday, January 16, 2020 at 7:30 AM PT/10:30 AM ET

EXTON, Pa., Jan. 14, 2020 (GLOBE NEWSWIRE) -- Idera Pharmaceuticals, Inc. (Nasdaq: IDRA), or Idera or the Company, today is providing an update on its tilsotolimod clinical development program and providing a corporate outlook for 2020.

“We made tremendous progress last year with the tilsotolimod clinical development program, and we are positioned well going into this pivotal year,” stated Vincent Milano, Idera’s Chief Executive Officer.  “Our ILLUMINATE-301 registrational trial of tilsotolimod in anti-PD-1 refractory metastatic melanoma is enrolling at a rate that dramatically exceeded our expectations.  We expect to complete enrollment this quarter, setting up the possibility of data before the end of this year.  We believe the rapid enrollment in this randomized trial is a testament to the critical unmet need for this patient group as well as to the growing appreciation from global investigators for both intratumoral administration and the mechanism of action of tilsotolimod.”

Continued Milano, “We also will add to the overall body of clinical evidence for tilsotolimod with additional data readouts expected in the second quarter.  Final analysis of ILLUMINATE-204 will include median overall survival (OS) for the first time, and ILLUMINATE-206 will provide safety and preliminary efficacy in microsatellite-stable colorectal cancer (MSS-CRC) as a triple combination of ipilimumab, nivolumab and tilsotolimod in this immunorefractory indication.”

“Lastly, we recently entered into a financing agreement that provides financial resources for these critical catalysts and beyond.  Overall, we are looking forward to 2020 and delivering on the goals we set for patients and our investors when we initiated the development of tilsotolimod.”

About Tilsotolimod (IMO-2125)
Tilsotolimod is an investigational TLR 9 agonist that received Fast Track Designation from the U.S. Food and Drug Administration (FDA) in 2017 for the treatment of anti-PD-1 refractory melanoma, in combination with ipilimumab as well as orphan drug designation from the FDA for the treatment of melanoma Stages IIb to IV. It signals the immune system to create and activate cancer-fighting cells (T-cells) to target solid tumors.  Currently approved immuno-oncology treatments, specifically check-point inhibitors, provide benefit for some patients, but these therapies are limited in patients whose immune responses are missing or weak. Intratumoral injections with tilsotolimod are designed to selectively enable the tumor-specific T-cells to recognize and attack cancers that remain elusive and unrecognized by the immune system exposed to checkpoint inhibitors alone, while limiting toxicity or impact on healthy cells in the body.

About Idera Pharmaceuticals
Harnessing the approach of the earliest researchers in immunotherapy and the Company’s vast experience in developing proprietary immunomodulatory platforms, Idera’s TLR agonist development program is focused on priming the immune system to play a more powerful role in fighting cancer, ultimately increasing the number of people who can benefit from immunotherapy. Idera also continues to focus on the acquisition, development and ultimate commercialization of drug candidates for both oncology and rare disease indications characterized by small, well-defined patient populations with serious unmet needs.
