Under the agreement, Jounce can utilize OncoSec’s gene delivery technology to evaluate in vivo efficacy in murine models of intratumorally-delivered therapeutic candidates. The agreement includes the GENESIS research generator and proprietary applicators developed for research use.
"We are excited to provide a preclinical delivery solution to Jounce for early-stage research purposes and expand the data set from our delivery technologies through our Technology Access Program," said Punit Dhillon, CEO and President of OncoSec. "Through the establishment of these programs, OncoSec benefits from extensive, multi-party characterization and validation of our proprietary, state-of-the art electroporation technologies. We are pleased to be working with Jounce to help advance their preclinical programs with these technologies."
"OncoSec has developed a unique delivery technology that will enable us to rapidly assess potential candidates in preclinical models," said Debbie Law, Jounce’s Chief Scientific Officer. "We are delighted to be working with OncoSec and leveraging their technology to help us evaluate our preclinical immunotherapy programs."
About OncoSec Research Technologies and Technology Access Program:
The OncoSec GENESIS research generator was developed specifically for gene electro-transfer. It features customizable electroporation parameters for construct-specific optimization of expression, and it is the only in vivo electroporation device enabled with TRACE Technology (Tissue-Based, Real-Time Adaptive Control Electroporation.)
TRACE technology incorporates an electrochemical tissue-sensing control system to automatically adjust pulse width and treatment duration in real time during the electroporation procedure. This feature enables tissue- and therapeutic-specific delivery optimization, maximizing uptake of the therapeutic while reducing unnecessary cell ablation or damage. In research models, GENESIS with TRACE has yielded higher and more consistent in vivo protein expression versus fixed-parameter electroporation, even in heterogeneous tissues.
Potential advantages of GENESIS with TRACE for use in murine models include robust and conformationally-native in vivo expression of difficult proteins, including GPCRs and receptors that function in multimeric form. Moreover, the consistent results obtained with these technologies in heterogeneous tissues support reliable intratumoral delivery of a wide variety of DNA-encodable therapeutics across multiple syngeneic, xenograft, and PDX models. Using these technologies, OncoSec has expressed more than fifty proteins in vivo, including multimers and structurally-complex fusion proteins, and no protein tested to date has failed to successfully express.
The OncoSec Technology Access Program makes OncoSec’s electroporation technologies available to collaborators for preclinical research. Devices are available for intratumoral, intradermal, and intramuscular delivery. For more information, please contact [email protected].
