SOUTH SAN FRANCISCO, CA, USA I April 02, 2017 I Five Prime Therapeutics, Inc. (FPRX), a clinical-stage biotechnology company focused on discovering and developing innovative immuno-oncology protein therapeutics, announced that a poster featuring data related to FPA154, Five Prime’s novel tetravalent anti-GITR antibody, was presented today at the 2017 American Association for Cancer Research (AACR) Annual Meeting in Washington, D.C. The poster titled “Development of FPA154, a Novel Tetravalent Anti-GITR Antibody, for the Treatment of Solid Tumors” is available at http://www.fiveprime.com/news-media/publications-presentations.
“Our differentiated tetravalent anti-GITR antibody, FPA154, demonstrates activity that appears to be superior to conventional bivalent antibodies,” said Luis Borges, Ph.D., Senior Vice President of Research at Five Prime. “These findings suggest our GITR agonist antibody has potent anti-tumor activity for the treatment of cancer, including in combination with PD-1 blockade, which suggests the potential for combination therapy.”
Five Prime is developing a novel anti-GITR antibody with enhanced agonist activity for the treatment of solid tumors. Preclinical studies have indicated that GITR-targeting agents inhibit tumor growth via two mechanisms: depletion and possibly suppression of Treg cells and direct agonism of effector T cells. FPA154 recruits antibody-dependent cellular cytotoxicity (ADCC) activity against cells that express high levels of GITR, such as Treg cells within the tumor microenvironment.
A single dose of a mouse-reactive surrogate cmFPA154 molecule demonstrated its ability to induce tumor T cell infiltration and inhibit tumor growth in multiple models. In addition, the surrogate cmFPA154 molecule demonstrated potent anti-tumor activity in combination with PD-1 blockade, even in the absence of Fc effector function, which suggests potential for combination therapy.
