OncoSec Medical Obtains Allowance of Key Patent Application for Intratumoral Delivery of Plasmid IL-15
SAN DIEGO-- OncoSec Medical Inc. (OTCQB: ONCS), a company developing DNA-based intratumoral cancer immunotherapies, announces that the United States Patent and Trademark Office (USPTO) has allowed claims covering a method of treating cancerous tumors with plasmid-encoded IL-15 and electroporation therapy to the tumor having a field strength of at least 700 V/cm. This announcement enhances OncoSec’s IP portfolio and provides significant support to the ongoing expansion of its immuno-oncology pipeline.
"This patent allowance by the USPTO demonstrates our strong overall commitment to protecting the innovation and commercial opportunity of our entire intratumoral immunotherapy product portfolio," said Punit Dhillon, president and chief executive officer, OncoSec Medical. “IL-15 is regarded as a promising immunotherapeutic agent, with several other companies evaluating IL-15 in clinical trials, as well as the National Institutes of Health. Our delivery approach of electroporation with plasmid IL-12 has demonstrated an excellent safety profile without unwanted toxicities. This patent allowance provides further evidence of OncoSec’s role as a leader in the development of intratumoral immunotherapies.”
IL-15 is a member of the family of IL-2 cytokines. This family of cytokines activates signaling pathways leading to cellular activation, proliferation and survival. Specifically, IL-15 exhibits broad activity and induces differentiation and proliferation of immune cells, such as Natural Killer (NK) cells, T cells and B cells. Furthermore, IL-15 reverses tolerance to tumor-associated antigens. Thus, IL-15 potentiates the immune system, which is important in the immune system’s ability to recognize and kill the cancer.
The allowed patent application joins a family of two issued U.S. patents: U.S. 8,026,223, which claims a method of treating cancerous tumors with plasmid-encoded IL-12 and electroporation therapy to the tumor; and U.S. 8,802,643, which claims a method of treating cancerous tumors with plasmid-encoded B7-1, a peripheral membrane protein found on antigen-presenting cells (APCs), and electroporation therapy to the tumor, both of which have a field strength of at least 700 V/cm. This patent family was exclusively licensed by OncoSec from the University of South Florida.
