Spring Bank Announces Additional Pre-Clinical Data on Its Second-Generation STING Agonist Program at the AACR Special Conference on Tumor Immunology and Immunotherapy

HOPKINTON, Mass., Nov. 29, 2018 (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 additional pre-clinical data from its second-generation STimulator of Interferon Genes (STING) agonist program.  Spring Bank will present the data in three poster presentations at the AACR Special Conference on Tumor Immunology and Immunotherapy being held on November 27-30, 2018 in Miami Beach, FL. 

Spring Bank is developing multiple second-generation STING agonist compounds that are designed to activate the innate and adaptive immune systems.  Spring Bank believes that its STING agonists are best-in-class agents and are differentiated due to their potential to be administered either intravenously (IV) or intratumorally (IT) for potent and durable anti-tumor activity in multiple cancer models.  Spring Bank’s STING agonists also have the potential to be used in combination with other therapeutic modalities to enhance efficacy. Subject to completion of IND-enabling studies, Spring Bank plans to initiate clinical trials for SB 11285 in 2019.  SB 11285 could be the first IV administered STING agonist to enter clinical development.

Poster B96, entitled Pharmacodynamic studies of SB 11285, a systemically bioavailable STING agonist in orthotopic tumor models, provides details on the self-assembly of SB 11285 into nanostructures that facilitate uptake into immune cells.  This poster also highlights that SB 11285 caused significant induction of type I interferon and other cytokines for anti-tumor activity in multiple orthotopic and subcutaneous mouse models.

Poster B88, entitled SB 11312, an active metabolite of SB 11285, is a potent and systemically bioavailable STING agonist, highlights the anti-tumor activity and favorable safety profile of SB 11312 when administered by both the IT and IV routes, as well as the synergistic activity of SB 11312 when combined with anti-PD1 antibody in syngeneic mouse models.

Poster B87, entitled Mechanistic insights into the anti-tumor activity of SB 11285 – a novel STING agonist, provides insights into the mechanism of action of SB 11285 and its analogs and describes the binding of SB 11285 to wild type and polymorphic variants of STING.  This poster also provides details on the dose-dependent production of type I IFNs, type II IFNs, other cytokines and chemokines by SB 11285 in human PBMCs.

All posters will be presented today from 5:00 to 7:00 pm Eastern Time at Americana 3 and 4 at the Loews Miami Beach Hotel and, following presentation, will be available on the Publications page of the company’s website.
