Data Supports Continued Dose Escalation and Further Investigation in Metastatic Renal Cell Carcinoma (mRCC)
MAINZ, Germany--(BUSINESS WIRE)-- EXUMA Biotechnology and affiliate Shanghai PerHum Therapeutics announced today interim results of two first-in-human solid tumor CAR-T products in subjects with recurrent or refractory stage IV metastatic renal cell carcinoma (mRCC). The data, presented at the Association for Cancer Immunotherapy (CIMT) 2019 Annual Meeting, continues to support the feasibility, comparative safety and pharmacokinetics of dose escalation of two CAR-T products, CCT301-38 (AXL) and CCT301-59 (ROR2), in a single patient population.
The umbrella clinical trial design being run at SPHCC (Shanghai Public Health Clinical Center) under the direction of lead investigator Tongyu Zhu, M.D., examines the first two CAR-T products in human clinical trial to use AND logic gate control technology. The logic gate design leverages the tumor microenvironment (TME) - turning the growth inhibitory acidic TME into an activating signal - thereby minimizing the potential of on-target, off-tumor activity. One trigger of the logic gate is the TME, and the other is the target antigen (AXL or ROR2, depending on the product). Some of the key highlights presented include:
"The cell processing feasibility, cell exposure and preliminary comparative safety of the two novel products support the potential of CAB-CAR-T technology for solid tumors," said Wendy Li, M.D., Chief Medical Officer of EXUMA Biotechnology. "We look forward to the complete data set from these ongoing clinical studies with collaborators and to bringing these programs forward into multicenter studies in the future."
The full abstract is now available on the annual CIMT meeting website (Abstract #123) and the poster will be presented on May 21, 9:00-11:30 am EST.
