Omeros to Present GPR174 Data at Upcoming American Association for Cancer Research Conference on Tumor Immunology and Immunotherapy

SEATTLE--(BUSINESS WIRE)--Nov. 8, 2019-- Omeros Corporation (Nasdaq: OMER) today announced an upcoming presentation entitled “Phosphatidylserine suppresses T cells through GPR174, and co-inhibition of adenosine receptors and GPR174 synergistically enhances T-cell responses” at the American Association for Cancer Research Conference on Tumor Immunology and Immunotherapy, which is being held November 17 - 20, 2019 in Boston, Massachusetts.

Marc Gavin, Ph.D., Omeros’ Director of Immunology, will present the company’s new findings that phosphatidylserine, a product of cell stress and death that is abundant in the tumor microenvironment (TME), directly stimulates GPR174 and attenuates T-cell responses.

Adenosine, another product of the TME, is well known to stimulate the same suppressive pathways through different GPCRs, and inhibition of both pathways—with adenosine receptor antagonists and with Omeros’ novel GPR174 inhibitors—results in maximal enhancement of T-cell function, which should translate to effective resistance to the immunosuppressive nature of the TME.

The data will also feature new findings from animal tumor models, which validate GPR174 inhibition for cancer immunotherapy.

Designated B45, the poster will be presented in Poster Session B on Tuesday, November 19, 4:30 p.m. to 7:00 p.m.
