F-star Therapeutics (“F-star”), a clinical-stage biopharmaceutical company focused on transforming the lives of patients with cancer through the development of innovative tetravalent bispecific (mAb2™) antibodies, today announces that new preclinical data on FS120, a mAb² product candidate targeting OX40 and CD137, will be presented at the Society for Immunotherapy of Cancer (SITC) 2019 Annual Meeting in National Harbor, Maryland, United States, being held from 06 - 10 November 2019.

FS120 is a potentially best-in-class dual agonist that has the potential to overcome cancer resistance by simultaneously engaging OX40 (CD134, TNFRSF4) and CD137 (4-1BB), two receptors found on the surface of tumor-infiltrating lymphocytes. Targeting this class of receptors using bispecific tetravalent binding mobilizes multiple arms of the immune system, which research shows is essential for eliminating tumors. F-star’s preclinical data demonstrated that FS120’s crosslink-dependent approach has the potential to provide therapeutic benefit, for example in combination with checkpoint antagonists, and reverse T cell exhaustion in immunosuppressive tumor environments.

Neil Brewis, CSO of F-star said “Recent clinical trials involving agonist molecules have reported that a meaningful anti-cancer response is often associated with liver toxicity, in line with preclinical observations. F-star’s OX40/CD137 mAb² antibody is showing preclinical evidence that an effective tumor-killing response can be decoupled from liver inflammation. We look forward to progressing FS120 into the clinic as we aim to potentially improve treatment outcomes for patients with difficult-to-treat cancers.”

Some CD137 agonist antibodies have been shown to induce adverse effects either in clinical or in preclinical studies as they constitutively activate T cells and thus release cytotoxic immunity outside of the tumor. In contrast, FS120 is designed to mitigate off-target toxicity through conditional, crosslink-dependent activation upon binding to both OX40 and CD137, which are predominantly present on T cells in the tumor microenvironment.

F-star expects to submit an IND application for FS120 during the fourth quarter of 2019.

Details of the poster are below:

Crosslink-independent CD137 agonism is associated with liver inflammation

Abstract poster number: P775
