Immune Design Updates Positive Data from Lead Cancer Immunotherapy Programs at ASCO Annual Meeting




SEATTLE and SOUTH SAN FRANCISCO, Calif., June 05, 2017 (GLOBE NEWSWIRE) -- Immune Design (Nasdaq:IMDZ), a clinical-stage immunotherapy company focused on oncology, today announced updated clinical and biomarker data for its lead immuno-oncology product candidates, CMB305 and G100. The data are being presented at the American Society of Clinical Oncology (ASCO) 2017 Annual Meeting in Chicago.

CMB305 Monotherapy in Soft Tissue Sarcoma Patients: Clinical Benefit, Safety and Patient Selection

Data in an oral presentation last Friday by Neeta Somaiah, M.D., Department of Sarcoma Medical Oncology, The University of Texas MD Anderson Cancer Center, highlight the results of 25 soft tissue sarcoma (STS) patients with recurrent disease treated with CMB305:

In a related presentation today, Seth M. Pollack, M.D. of the Fred Hutchinson Cancer Research Institute, will present data examining the relationship between immune response against NY-ESO-1 and clinical benefit in a combined set of CMB305 and LV305 patients (n=64) with various tumor types. LV305 is the vector only, "prime" component of CMB305, and was the subject of a separate Phase 1 study:

G100 Monotherapy in Follicular NHL (FL) Patients: Clinical Benefit, Safety and Changes to the Tumor Microenvironment (TME)

In a poster presentation today, Christopher Flowers, M.D., Department of Hematology and Medical Oncology, Emory University School of Medicine, will present results of 9 patients with FL treated with escalating doses of G100 monotherapy (with local radiation (XRT)).

"These data demonstrate that both CMB305 and G100, our lead cancer immunotherapy product candidates, are capable of activating patients' immune systems in ways that have a direct effect on patients' tumor growth, whether it is tumor-growth arrest on CMB305 therapy and subsequent survival benefit, or ORR and systemic tumor shrinkage after local therapy with G100," said Sergey Yurasov, MD, PhD, Senior Vice President and Chief Medical Officer at Immune Design. "Also, importantly, we are evaluating immune biomarkers that may identify patients who are likely to benefit the most from CMB305 therapy. We plan to present these clinical data to regulatory agencies in planning for a pivotal trial that may lead to subsequent regulatory approval, and enable us to bring these novel, safe immunotherapies to cancer patients."

About CMB305

CMB305 is a prime-boost vaccine approach against NY-ESO-1-expressing tumors, designed to generate an integrated, anti-NY-ESO-1 immune response in vivo via a targeted, specific interaction with dendritic cells, a mechanism of action Immune Design believes differs from traditional cancer vaccines. CMB305 is being evaluated in STS patients in ongoing Phase 1 monotherapy and 2 combination studies with the anti-PD-L1 antibody, Tecentriq® (atezolizumab), pursuant to a collaboration with Genentech. Immune Design has received Orphan Drug Designation for CMB305 from the U.S. Food and Drug Administration (FDA) for the treatment of soft tissue sarcoma, as well as from the FDA and European Medicines Agency for each of the components of CMB305 for the treatment of soft tissue sarcoma.

About G100

G100 contains a potent synthetic small molecule toll-like receptor-4 (TLR-4) agonist, Glucopyranosyl Lipid A (GLA), and is the lead product candidate in Immune Design's Antigen Agnostic approach. It leverages the activation of both innate and adaptive immunity, including dendritic cells, in the tumor microenvironment to create an immune response against the tumor's preexisting diverse set of antigens. G100 is being evaluated as both a monotherapy (with XRT) and in combination with Merck's anti-PD-1 agent, Keytruda® (pembrolizumab), pursuant to a clinical collaboration with Merck, in a randomized Phase 1/2 trial in patients with follicular non-Hodgkin's lymphoma. The FDA has granted Orphan Drug Designation for G100 for the treatment of follicular non-Hodgkin's lymphoma.

About Immune Design

Immune Design is a clinical-stage immunotherapy company employing next-generation in vivo approaches to enable the body's immune system to fight disease. The company's technologies are engineered to activate the immune system's natural ability to generate and/or expand antigen-specific cytotoxic T cells, while also enhancing other immune effectors, to fight cancer and other chronic diseases.  CMB305 and G100, the two leading product candidates focused in cancer immunotherapy, are the first products from its two separate discovery platforms targeting dendritic cells in vivo, ZVex® and GLAAS® , the fundamental technologies of which were licensed from the California Institute of Technology and the Infectious Disease Research Institute (IDRI), respectively. Both ZVex and GLAAS also have potential applications in infectious disease and allergy as demonstrated by ongoing pharmaceutical collaborations.  Immune Design has offices in Seattle and South San Francisco.
