Idera Pharmaceuticals has entered into a clinical development support agreement with Pillar Partners.  Under the terms of the agreement Pillar Partners will provide direct funding to support three investigator initiated clinical trials to further strategically expand the clinical research of IMO-2125, Idera’s toll-like receptor (“TLR”) 9 agonist into broader melanoma populations and other solid tumors. For these trials, Idera will provide IMO-2125.  Idera is currently enrolling a Phase 3 (“ILLUMINATE-301”) trial of intratumoral administration of IMO-2125 in combination with ipilimumab in patients with anti-PD-1 refractory metastatic melanoma.

The three trials within the terms of this agreement are:

• A Phase 1/2 open label study of intratumoral IMO-2125 in combination with intratumoral ipilimumab and IV nivolumab in a protocol open to multiple tumor types including non-small cell lung cancer (“NSCLC”), melanoma, squamous cell carcinoma of the head and neck and urothelial carcinoma. The principal investigator initiating this trial is Aurélien Marabelle, MD, PhD, Clinical Director of the Cancer Immunotherapy Program at Institut Gustave Roussy, Villejuif, France.
• A Phase 2 study of intratumoral IMO-2125 in combination with IV pembrolizumab in patients with NSCLC. The principal investigator initiating this trial is Arafat Tfayli, MD, FRCP, Professor of Clinical Medicine, Director of Research, NK Basile Cancer Institute, American University of Beirut Medical Center, Beirut, Lebanon.
• A Phase 2 placebo controlled study of intradermal administration of IMO-2125 in patients with T3/T4 primary melanoma scheduled to undergo a combined re-excision and sentinel node biopsy procedure. The principal investigators initiating this trial are Bas Koster, MD, Fons van den Eertwegh MD, PhD, and Tanja de Gruijl, PhD, who is Professor of Translational Tumor Immunology and Co-Director of the Cancer Immunology Program at the VU University Medical Center, Cancer Center Amsterdam, The Netherlands.

“We are eager to expand our knowledge and understanding of the various cancer types and combinations in which IMO-2125 can play a significant role in improving outcomes beyond our current registrational focus with our ILLUMINATE 301 program,” stated Joanna Horobin, M.B., Ch. B., Idera’s chief medical officer. 

“We look forward to working with these investigators to provide the support they need to initiate these trials before the end of the year,” said Shah Rahimian, MD, Idera’s Oncology medical lead.
