BRANFORD, Conn., Nov. 13, 2017 (GLOBE NEWSWIRE) — BioXcel Therapeutics (“BTI”), a biopharmaceutical company committed to developing novel drugs targeting immuno-oncology and neurological and psychiatric diseases, announced today that Nektar Therapeutics and BTI have entered into a research collaboration to explore the novel combination of Nektar’s NKTR-214, a CD122-biased agonist, and BTI’s BXCL701, a small molecule immune-modulator and DPP 8/9 and FAP inhibitor, for the treatment of multiple oncology indications.
NKTR-214 is an investigational immuno-stimulatory therapy designed to expand specific cancer-fighting CD8+ effector T cells and natural killer cells directly in the tumor micro-environment and increase expression of PD-1 on these immune cells. NKTR-214 targets CD122 specific receptors found on the surface of these cancer-fighting immune cells in order to stimulate their proliferation. BXCL701 is an inhibitor of dipeptidyl peptidases (DPPs) 8 and 9 and fibroblast activation protein (FAP) in immune cells and induces expression of a wide range of pro-inflammatory cytokines and chemokines.
The goal of this collaboration is to leverage the complementary mechanisms of NKTR-214 and BXCL701 to boost the body’s own immune system and overcome local immunosuppressive mechanisms in the tumor microenvironment. The collaborative research studies will evaluate the potential of the therapies in preclinical mouse models of pancreatic and prostate cancer.
“Combination immunotherapy represents a potentially groundbreaking innovation in cancer treatment. We are hopeful that experimental research studies of these two agents will translate into an immune mediated anti-cancer benefit,” said Dr. Vince O’Neill, Chief Medical Officer of BioXcel Therapeutics. “The complementary mechanisms of BXCL701 and NKTR-214 may stimulate both innate and acquired immune responses while inhibiting the immuno-suppressive effect of the tumor microenvironment, representing a significant potential opportunity to develop a novel therapy to fight cancer.”
“We’re pleased to be collaborating with BTI, to understand the potential of NKTR-214 with BXCL701 as a combination therapy. The preclinical studies outlined in this collaboration target difficult to treat tumors and allow us to evaluate efficacy and the underlying immunological mechanism of the combination,” said Jonathan Zalevesky, Senior Vice President, Biology & Preclinical Development of Nektar Therapeutics. “The results obtained from these collaborative studies may inform future rational combination therapies that could be effectively translated into new treatment options for cancer patients.”
