Release Details

9 of 10 Waldenstrom’s Macroglobulinemia Patients Treated at the Highest Dose have Demonstrated Reductions in IgM or M-Protein Levels in Ongoing Trial

Company is on Track to Deliver Data from 4 Clinical Trials over Next 6 to 18 Months

CAMBRIDGE, Mass. and EXTON, Pa., May 09, 2016 (GLOBE NEWSWIRE) -- Idera Pharmaceuticals, Inc. (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, 2016.

“Idera continued to make strong progress across all of our areas of focus during the first period of 2016,” stated Vincent Milano, Idera’s Chief Executive Officer. “Our clinical development teams have transformed our programs into executable registration strategies and the research group continues to advance the 3GA platform to put us into position to enter human proof of concept trials in 2017.”

Continued Milano, “The amount of strategic consideration and effort that has taken place over the past year and the related execution should provide us with critical catalysts beginning in the second half of this year and right through the course of 2017 across all aspects of our business.  We’re currently conducting four separate clinical trials and we expect data from all four of these studies over the course of the next six to 18 months. This is an exciting time for Idera and we look forward to a very bright future for the patients we aim to serve as well as our investors, who support these bold endeavors.”

Research and Development Program Updates
IMO-8400 and IMO-2125 are our lead clinical development drug candidates.  IMO-8400 is an oligonucleotide-based antagonist of Toll-like receptors (TLRs) 7, 8, and 9.  IMO-2125 is an oligonucleotide-based agonist of TLR9.  The company also announced during the fourth quarter of 2015, the first two development targets from its proprietary 3GA Technology platform:  NLRP3 (NOD-like receptor family, pyrin domain containing protein 3) and DUX4 (Double Homeobox 4).  The company plans to take the first 3GA candidate into human proof of concept studies in 2017.

Toll-like Receptor (TLR) Agonism

Immuno-Oncology Program
Idera’s development program in immuno-oncology is based on pre-clinical studies that demonstrated through the mechanism of intra-tumoral injections of the TLR9 agonist, IMO-2125, the tumor microenvironment could be impacted in a manner which positively increases the efficacy of check-point inhibition.  These studies have led Idera into a strategic research alliance with the University of Texas MD Anderson Cancer Center to clinically explore the combination of checkpoint inhibitors.

In December 2015, Idera announced the initiation of a Phase 1/2 clinical trial of intra-tumoral IMO-2125 in combination with Ipilimumab in patients with relapsed or refractory Metastatic Melanoma being conducted at the University of Texas MD Anderson Cancer Center.  The study will also include an arm exploring the combination of IMO-2125 with a PD1 inhibitor. The company expects to present the first translational data from the trial during the second half of 2016, with clinical results expected in 2017.

Additionally, the company presented new preclinical data demonstrating the potentiation of anti-tumor effects through combination of IMO-2125 and indoleamine-pyrolle 2,3-dioxygenase (IDO-1) in cancer models at the American Association for Cancer Research (AACR) Annual Meeting.

Toll-like Receptor (TLR) Antagonism

Genetically Defined Forms of B-cell Lymphoma
Idera’s program in genetically defined forms of B-cell lymphoma is based on pre-clinical studies that have demonstrated in certain B-cell lymphomas driven by the oncogenic MYD88-L265P mutation, blocking TLR7 and 9 signaling can promote tumor cell death.

In December 2015, Idera presented positive clinical data from the ongoing Phase 1/2 trial of IMO-8400 in patients with Waldenstrom’s Macroglobulinemia at the 57^th Annual Meeting of the American Society of Hematology (ASH) in Orlando, FL.  The company is continuing further dose escalation of IMO-8400 in both the ongoing trials in Waldenstrom’s Macroglobulinemia and Diffuse Large B-cell Lymphoma to further explore the full potential of IMO-8400 based on the safety profile and efficacy signals seen to date.  The company expects to complete the accrual of the escalated dosing for both the WM and DLBCL studies by the end of 2016, with data available in the first half of 2017.

Idera previously announced that the U.S. Food and Drug Administration (FDA) granted orphan drug designation for IMO-8400 for the treatment of Waldenström’s macroglobulinemia and DLBCL.

Rare Diseases
In November 2015, Idera announced the initiation of a Phase 2 clinical trial of IMO-8400 in patients with Dermatomyositis.  The company expects to have the DM Phase 2 study fully enrolled in the first half of 2017.

The company announced during the first quarter of 2016 that due to the resources required to fully commit to a Duchenne muscular dystrophy (DMD) clinical development endeavor, the company has chosen to suspend internal efforts at this time to advance IMO-8400 into clinical development for DMD.

Third Generation Antisense Platform

Throughout 2015, the company undertook an analysis and prioritization of oncology and rare disease indications for potential development of drug candidates derived from our 3GA technology platform.  The key considerations in identifying disease indications from our third generation antisense program included: strong evidence that the disease is caused by a specific protein; clear criteria to identify a target patient population; biomarkers for early assessment of clinical proof-of-concept; a targeted therapeutic mechanism for action; and unmet medical need to allow for a well-defined development path to approval and commercial opportunity.  As a result of this analysis, in the fourth quarter of 2015 Idera announced the selection of NLRP3 (NOD-like receptor family, pyrin domain containing protein 3) and DUX4 (Double Homeobox 4) as initial gene targets to advance into IND-enabling activities, which will occur throughout 2016.  Potential disease indications include, but are not limited to interstitial cystitis, uveitis and facioscapulohumeral muscular dystrophy (FSHD), respectively.  The company is currently conducting clinical and regulatory pathway and commercial analysis activities and conducting IND-enabling studies with the plan to enter the clinic in 2017 for the first disease indication.
