OncoSec Secures License for Electroporation Intellectual Property from University of South Florida

Exclusive License Extends Patent Protection for ImmunoPulse Technology

SAN DIEGO – September 11, 2012 – OncoSec Medical Inc. (OTCBB: ONCS), a company developing its advanced-stage ImmunoPulse and NeoPulse therapies to treat solid tumor cancers, announced it has secured an exclusive license for specific patented technology from the University of South Florida Research Foundation (USFRF) relating to the delivery of gene-based therapeutics via intratumoral and intramuscular electroporation. This patent is directly related to the ongoing Phase II trials for metastatic melanoma, Merkel cell carcinoma and cutaneous T-cell lymphoma using the company’s ImmunoPulse therapy, and extends patent protection for the ImmunoPulse technology to the year 2024. Financial terms of this agreement were not disclosed.

OncoSec’s proprietary gene and drug delivery platform, the OncoSec Medical System (OMS) electroporation device, is currently being used to develop the company’s ImmunoPulse and NeoPulse therapies. This platform encompasses patents, technology and other intellectual property for intratumoral methods for delivering drugs and gene-based treatments in humans.

ImmunoPulse involves the application of a brief electric field to the surface of the skin. This temporarily opens pores in the cell membrane, allowing anti-cancer agent DNA IL-12, to be absorbed more efficiently. DNA IL-12, which normally has difficulty penetrating the tumor cell membrane to get inside these cells, has been shown to significantly stimulate the immune system’s T-cells to fight the cancer. The new license from USFRF complements OncoSec’s seminal patents, particularly for the protection of the methods involved in the ImmunoPulse treatment, and specifically for the use of DNA IL-12.

“Our licensing agreement with the USFRF significantly strengthens OncoSec’s intellectual property rights in the area of gene and drug delivery via in vivo electroporation,” said Punit Dhillon, OncoSec’s President and CEO. “We anticipate that the further development of this technology will enhance the ability of ImmunoPulse to address the serious unmet need among patients with skin cancer. OncoSec’s patent portfolio places us in a preeminent position within the field of electroporation-based delivery of gene-based treatments for cancer.”

“OncoSec is the ideal choice to further develop this technology that I and my colleagues pioneered while working at the University of South Florida, and I am pleased they have secured this license,” said Richard Heller, Ph.D., author of the patented technology. “The technology involves short-pulsed electric fields that can deliver plasmid DNA to stimulate the immune system. As a result, it is a natural fit with OncoSec’s ongoing program to develop its ImmunoPulse therapy.”

 

 

SAN DIEGO – September 5, 2012 – OncoSec Medical Inc. (OTCBB: ONCS), a company developing its advanced-stage ImmunoPulse and NeoPulse technologies to treat solid tumor cancers, received a new Method of Use and Device patent (Patent Application No. 200780014313.0, “Method and Device for Treating Microscopic Residual Tumors Remaining in Tissues Following Surgical Resection”) for the OncoSec Medical System (OMS) electroporation device platform from the State Intellectual Property Office of the People’s Republic of China. The issuance of this patent has the potential to expand OncoSec’s commercial opportunities for minimally invasive and surgical procedures to treat solid tumors in a very large market such as China.

Punit Dhillon, OncoSec’s President and CEO, commented, “The issuance of this patent is significant, because the Chinese authorities have given the company patent approval for our claims regarding the OMS electroporation device itself, as well as the method of use. These are broad claims, wherein OncoSec now has the ability to deliver various therapeutic agents through its electroporation device, including bleomycin and DNA IL-12, as well as to treat tumors with these agents following surgical resection. Thus, this patent will act as a part of the company’s core strategy as we continue to develop and build our commercialization strategy in China, one of the largest emerging oncology markets.”

Numerous research studies have concluded that cancer has now become a leading cause of mortality in China, representing 25 percent of all deaths in urban areas and 21 percent in rural areas. Moreover, cancer mortality in China has been increasing rapidly and continuously during the past three decades, which indicates a significant need for novel therapies.

ImmunoPulse and NeoPulse are investigational therapies being evaluated to reduce the rate of cancer recurrence while minimizing quality-of-life side effects. These therapeutic approaches, as potential adjuncts to surgery, involve injecting the tumor with an anti-cancer agent, followed by electroporation to open up the cell membrane, which helps significantly increase the uptake of the agent. This approach has been shown to selectively kill cancer cells that may exist in the neighboring tissue, which may result in a reduced rate of recurrence and has the potential to complement standard-of-care surgical procedures.
