Yale Cancer Center to Present on the Synergistic Relationship Between Intravenously-Administered SB 11285, Spring Bank’s STING Agonist Development Compound, and Radiation Therapy in Cancer at the 2019 ASTRO Annual Meeting

Hopkinton, Massachusetts, UNITED STATES

HOPKINTON, Mass., Sept. 17, 2019 (GLOBE NEWSWIRE) -- Spring Bank Pharmaceuticals, Inc. (Nasdaq: SBPH), a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of viral infections, inflammatory diseases and certain cancers, today announced that Dr. Thomas Hayman, MD, Ph.D., a resident in the Department of Therapeutic Radiology at Yale Cancer Center, will present at the 2019 ASTRO Annual Meeting. Dr. Hayman will discuss the results from the study of activating the STimulator of INterferon Genes (STING) pathway using SB 11285, Spring Bank’s intravenously (IV)-administered STING agonist development compound, in combination with radiation therapy.

The results demonstrated that the addition of IV SB 11285 to radiation therapy enhanced effectiveness in killing tumors vs. radiation alone in pre-clinical models. The addition of IV SB 11285 showed a synergistic effect in shrinking tumors when combined with radiation in xenograft models of head and neck tumors in mice. Previous data have shown that SB 11285 is effective in tumor growth inhibition in multiple pre-clinical models of cancer. Spring Bank recently announced that its Investigational New Drug application for a Phase 1 trial of IV SB 11285 was cleared by The U.S. Food and Drug Administration for clinical testing, and Spring Bank anticipates that a Phase 1 trial for IV SB 11285 will begin shortly.

“The results from our studies presented at the 2019 ASTRO Annual Meeting provide the molecular details of the benefits to combining radiation and STING agonists and determining the mechanism of why they work well together,” said Dr. Thomas Hayman of Yale Cancer Center.

The presentation, Whole Genome CRISPR- Cas9 Screen Identifies STING as a Determinant of Intrinsic Radiosensitivity in Head and Neck Squamous Cell Carcinoma, will be delivered by Dr. Hayman (presentation 159) on Tuesday September 17, 2019 at the 2019 ASTRO Annual Meeting in Chicago, Illinois. Dr. Hayman’s presentation is part of the SS 27 - Biology 6 - Experimental Therapeutics and Target Discovery workshop.

“The exciting results from this research conducted at Yale Cancer Center highlight a new opportunity for the clinical expansion of SB 11285 and could present additional treatment options for patients,” said Kevin Leach, Ph.D., Spring Bank’s Vice President, Nonclinical & Translational Research. “We will leverage the findings from this research in our ongoing clinical development plan for IV SB 11285 monotherapy as well as in combination with other therapies in multiple tumor types.”
