“These preclinical findings suggest that the surrogate antibody for FPA008 significantly reduces tumor growth in murine syngeneic tumor models when administered alone and when administered in combination with a PD-1 antibody,” said Kevin Baker, Ph.D., Senior Vice President of Development Sciences at Five Prime. “These findings support previous preclinical data that served as the basis for our Phase 1a/1b clinical trial that we are running in collaboration with Bristol-Myers Squibb (BMS) to investigate the use of cabiralizumab in combination with nivolumab (anti-PD-1, OPDIVO®) in six different tumor types.”
The colony stimulating factor 1 receptor (CSF-1R) signaling pathway promotes tumor progression via the recruitment, differentiation, and survival of immuno-suppressive, M2 polarized, tumor-associated macrophages (TAMs). Five Prime has developed cabiralizumab (FPA008), an IgG4 antibody against CSF-1R that blocks the ability of both CSF-1 and IL-34 to bind and activate this receptor, thereby modulating the immune response to tumorigenesis.
Five Prime has identified alterations in the tumor microenvironment that occur upon CSF-1R inhibition, including significant reduction of immunosuppressive M2 TAMs and an increase in tumor PD-L1 expression. Notably, when dosing in combination, the blockade of CSF-1R and PD-1/PD-L1 results in a significant increase in CD8+ T cells within the tumor. The results show that, when added to PD-1/PD-L1 blockade, the surrogate antibody for FPA008 can significantly enhance anti-tumor efficacy.
