EXTON, Pa., April 23, 2020 (GLOBE NEWSWIRE) -- Idera Pharmaceuticals, Inc.

EXTON, Pa., April 23, 2020 (GLOBE NEWSWIRE) -- Idera Pharmaceuticals, Inc. ("Idera") (Nasdaq: IDRA) today announced that updates on ILLUMINATE-206 and ILLUMINATE-101, two studies investigating intratumoral tilsotolimod, Idera's investigational Toll-like receptor 9 (TLR9) agonist, will be presented at the American Association for Cancer Research (AACR) Virtual Annual Meeting I , to be held April 27-28, 2020, as part of a "Clinical Trial Poster Session."

ILLUMINATE-206 is an ongoing phase 2, open-label, multicohort, multicenter study to test the safety and efficacy of intratumoral tilsotolimod in combination with Yervoy®* (ipilimumab) and Opdivo® (nivolumab) for the treatment of solid tumors. The trial initiated in September 2019 with the microsatellite stable colorectal cancer (MSS-CRC) cohort. A description of the trial in progress will be presented.

ILLUMINATE-101 was a phase 1b trial of intratumoral tilsotolimod monotherapy in patients with refractory solid tumors, which was completed in December 2019. Final results will be presented.

Hani M. Babiker, M.D., from the University of Arizona Cancer Center will present both studies. The abstract titles are as follows:

  • Abstract # 10614: Tilsotolimod engages the TLR9 pathway to promote antigen presentation and Type-I IFN signaling in solid tumors
  • Abstract # 10591: A phase 2 multicenter study to evaluate the efficacy of tilsotolimod in combination with nivolumab and ipilimumab for treatment of microsatellite-stable colorectal cancer (ILLUMINATE-206)  

"We are very pleased that Dr. Babiker from the University of Arizona Cancer Center will present information from our studies investigating tilsotolimod in solid tumors," stated Elizabeth Tarka, M.D., Idera's Chief Medical Officer. "We continue to be excited about the broader potential of tilsotolimod beyond melanoma."

The abstracts and video presentations will be available at 12:01 AM ET on Monday, April 27. Video presentations will be available for viewing on demand through the virtual meeting platform.

About Tilsotolimod (IMO-2125)

Tilsotolimod is an investigational, synthetic Toll-like receptor 9 agonist. Intratumoral injection of tilsotolimod has been shown to promote both innate and adaptive immune activation. Tumors with an active immune response appear to respond better to CPIs than those that exclude or inhibit anti-tumor immune cells. Tilsotolimod in combination with CPIs may cause regression of locally injected and distant tumor lesions and increase the number of patients who benefit from immunotherapy.

Tilsotolimod has received both Fast Track designation and Orphan Drug designation from the FDA and is being evaluated in multiple tumor types and in combination with multiple checkpoint and costimulation therapies. For more information on tilsotolimod trials, please visit .
