Fapon Biopharma Announces FDA Approval of IND for FP008, a First-in-Class Immunotherapy for Solid Tumors

PD1 targeted antibodies drive the differentiation of effector CD8(+) T cells into terminally exhausted status. In the latest pre-clinical experiment conducted by Fapon Biopharma, FP008 effectively counteracted this process through IL-10M, significantly reducing the anti-PD-1 antibody-mediated exhaustion of CD8(+) T cells. In mouse experiments, FP008 exhibited potent anti-tumor effects, significantly increased the infiltration of intratumoral CD8(+) T cells, reduced their terminal exhaustion differentiation and enhanced the ability of terminally exhausted CD8(+) T cells to produce and secrete IFN-γ and GZMB. In addition, FP008 showed encouraging safety and pharmacokinetics profile in cynomolgus monkey, and demonstrated favorable developability.

This breakthrough offers a new treatment choice for patients who have limited options and could potentially transform the treatment paradigm for solid tumors. Fapon Biopharma is actively seeking strategic partnerships with biopharmaceutical companies worldwide to co-develop FP008 through clinical trials or further commercialization.

"Global collaboration is central to our vision," stated President Vincent Huo. "We invite partners to leverage our robust preclinical data and clinical-stage asset to jointly advance innovative products in tumor immunotherapy."
