In a keynote presentation entitled: "Advances in Clinical Electroporation: Tissue Sensing, Feedback Control, and Catheter Technology," Robert H. Pierce, MD, Chief Scientific Officer, discussed OncoSec’s advances in intratumoral gene electro-transfer, using ‘smart’ tissue-sensing technology and the development of catheter-based electrodes, enabling treatment of deep and visceral tumors.

"We are excited to be presenting our engineering advances at the First World Congress," said Dr. Pierce. "The development of minimally-invasive electroporation devices capable of high-efficiency delivery of immunotherapeutic genes into tumors located anywhere in the body is critical to establishing intratumoral EP-mediated gene therapy as a standard therapeutic modality in immuno-oncology."

OncoSec’s New Catheter Electrode Technology

OncoSec’s new catheter-based electrodes are designed to be compatible with standard medical instrumentation, allowing access to deep and visceral tumors, where they are capable of anchoring to and treating the tumor using OncoSec’s proprietary technology. These all-in-one devices have the ability to inject a DNA-based agent, while deploying electrodes to perform electroporation in a single procedure. Moreover, these devices have an adjustable needle and electrode penetration depth allowing clinicians to treat tumors of varying dimensions to perform minimally invasive intratumoral immunotherapy.

Development of Tissue Sensing and Feedback Control

OncoSec is developing ‘smart’ electroporation technology capable of tissue sensing and real-time feedback control of electroporation pulse trains in order to attain optimal gene transfer and minimal electroporation-mediated tissue damage. Dr. Pierce added: "Taken together, these engineering advances can enable access and high-efficiency gene delivery to tumors throughout the body. This is key as we move forward in developing OncoSec’s pipeline of novel intratumoral therapies."

"Our partnership with Rev.1 Engineering and internal bioengineering expertise have allowed OncoSec to enhance our ImmunoPulse platform and position the Company as a leader in gene electro-transfer technologies in cancer immunotherapy," said Punit Dhillon, President and CEO of OncoSec. "We are also strengthening our intellectual property portfolio in the area of gene and drug delivery via electroporation to reach visceral tumors and enhance the uptake of therapeutic agents."

Licensing of University of South Florida Catheter Electrode Patent

OncoSec secured an exclusive license for a specific patented technology from the University of South Florida Research Foundation (USFRF). The patent provides a device and related methods to deliver molecules to cells that comprise any tissue. The patent includes a catheter-based electrode and methods to deliver molecules to cardiac tissue, blood vessels, other tissues/organs that can be accessed through a luminal tissue and luminal tissues. The device also functions as a non-catheter based electrode for performing the same functions. Financial terms of this agreement were not disclosed.
