F1 Oncology Announces Development Milestone and $10M Equity Investment

Precision medicine-directed trial of AXL and ROR2 targeted conditionally active CAR-T cellular products to enroll patients with refractory, metastatic kidney cancer


Shanghai, PRC and West Palm Beach, FL – January 7th, 2018 – F1 Oncology, Inc., a biotechnology company discovering and developing adoptive cellular therapies (ACTs) for solid tumors, today announced receipt of a $10 million equity investment from its current investors upon ethics committee approval of a novel precision medicine-directed trial sponsored by Shanghai Sinobioway Sunterra Biotechnology and its hospital collaborators for two novel chimeric antigen receptor T cell (CAR-T) products for the treatment of metastatic renal cell carcinoma (mRCC).

The two conditionally active CAR-T cellular products targeting AXL and ROR2 will be tested in subjects with refractory, advanced stage mRCC. CCT301-38 AXL and CCT301-59 ROR2 were evolved and molecularly engineered into CAR-T products to provide tumor microenvironment (TME) control over CAR-T receptor ligand binding, cytokine release, and cell lysis. Each cellular product additionally contains a cell removal epitope for antibody mediated removal. Both cellular products are processed using a 3rd generation suspension-based lentiviral system and proprietary T cell closed cell processing system developed by F1 Oncology.

The precision medicine-driven clinical trial will enroll patients with multi-organ, recurrent/refractory metastatic renal cell carcinoma based on expression of the AXL or ROR2 targets in tumor biopsy. Eligible subjects will be assigned to one of two arms via immunohistochemistry (IHC) analysis of AXL and ROR2 expression in a parallel dose escalation design in Stage A followed by cohort expansion in Stage B after data safety monitoring board review. Safety, cellular kinetics, and objective response by RECIST 1.1 with central radiology review will be performed on subjects enrolled in each arm of the study. Study results for each arm will be reported at the completion of Stage A and the completion of Stage B, including interim follow-up findings for durability of response, cellular persistence, and safety.

“Our appreciation for the unique technologies at F1 Oncology has been validated by the close working collaboration between the two organizations,” stated Wu Zili, Director and founder of Shanghai Sinobioway Sunterra Biotechnology. “The future potential benefit to many Chinese patients from this work is a continuous motivation.”

“We look forward to reviewing the outcome of this innovative clinical approach with two CAR-T products against a single malignancy in a target-driven trial,” stated Gregory Frost, Ph.D. Chairman & CEO of F1 Oncology. “The clinical investigation of these first tumor microenvironment-controlled CAR-T products, each with unique targets and activating domains and properties, will advance the field towards the objective of making CAR-T more broadly applicable to patients suffering from solid tumor malignancies”.

F1 Oncology combines its US partner, BioAtla LLC’s, CAB technology with F1 Oncology’s proprietary technologies to develop and commercialize CAB-CAR-T therapies and other ACTs for the treatment of solid tumor malignancies. CAB-CAR-T cell therapies are designed to be conditionally active only in the tumor microenvironment, and may therefore help reduce potential adverse events associated with on-target, off-tumor effects of CAR-T therapies.
