OncoSec Strengthens IP Portfolio with Three New Patents Covering TAVO(TM) and Its Electroporation Gene Delivery System

PENNINGTON, N.J. and SAN DIEGO, May 27, 2020 /PRNewswire/ -- OncoSec Medical Incorporated (NASDAQ:ONCS) (the "Company" or "OncoSec"), a company developing late-stage intratumoral cancer immunotherapies, today announced Notices of Allowance for three new patent applications covering its interleukin-12 (IL-12) based immunotherapy platform, including its lead product candidate TAVO(TM) and next-generation product candidate TAVO(PLUS), and electroporation gene delivery system.

    --  The European Patent Office intends to grant a patent covering OncoSec's
        gene therapy and electroporation for the treatment of malignancies. The
        allowed European claims are directed to methods of treating cancer by
        delivering a plasmid encoding an agonist of GITR, CD137, CD134, CD40L,
        or CD27 (immune co-stimulators) in combination with a plasmid encoding
        an immunostimulatory cytokine (such as IL-12 or IL-15) to a tumor by
        intratumoral electroporation. This patent is significant as it further
        expands protection of OncoSec's IL-12 based immunotherapy platform in a
        key market for various drug combinations.

    --  Additionally, the European Patent Office also intends to grant a second
        patent protecting OncoSec's next-generation electroporation gene
        delivery system focused on the treatment of internal or visceral
        lesions. Specifically, the allowed claims cover OncoSec's innovative
        visceral lesion applicator (VLA) that can be used with the APOLLO(TM)
        electroporation generator, including applicators with two or more
        electroporation electrodes and a central channel for colocalized drug
        delivery. These innovative devices allow targeted electroporation and
        treatment of cells with therapeutic moieties using a single device. The
        applicator options enable the ability to use a variety of interventional
        and surgical approaches to access a wide variety of lesions, such as
        distal lung metastases (catheter-based) and primary and metastatic liver
        tumors (rigid-based). This is clinically significant because many of
        these cancers are difficult to reach and treat directly with an
    --  The Canadian Intellectual Property Office intends to grant a patent
        protecting OncoSec's electroporation method for treating microscopic
        tumors. The allowed claims are directed to delivery of a gene encoding a
        therapeutic protein, such as a cytokine, including electroporation to
        reduce tumor growth and metastases in the tumor margin tissue. Tumor
        resection, if performed, can be done before or after the
        electroporation. Treatment of tumor margin tissue - prior to and
        following resection - is a very meaningful treatment advancement for
        OncoSec, particularly when directed to the prevention of metastases.

"OncoSec continues to prioritize the expansion of its intellectual property portfolio across multiple facets of its technology," said Keir Loiacono, Vice President, Corporate Development at OncoSec Medical Incorporated. "These three new allowances demonstrate OncoSec's strong patent position in three critical areas: device development, new treatment alternatives and novel adjuvant therapies with previously undescribed combinations. As we look to the future, we believe this will not only help to secure our competitive position in the intratumoral oncology space, but potentially create new opportunities for licensing revenue."

About OncoSec Medical Incorporated
OncoSec Medical Incorporated (the "Company," "OncoSec," "we" or "our") is a late-stage biotechnology company focused on developing cytokine-based intratumoral immunotherapies to stimulate the body's immune system to target and attack cancer.?OncoSec's lead immunotherapy investigational product candidate - TAVO(TM) (tavokinogene telseplasmid) - enables the intratumoral delivery of DNA-based interleukin-12 (IL-12), a naturally occurring protein with immune-stimulating functions.?The technology, which employs electroporation, is designed to produce a controlled, localized expression of IL-12 in the tumor microenvironment, enabling the immune system to target and attack tumors throughout the body. OncoSec has built a deep and diverse clinical pipeline utilizing TAVO(TM) as a potential treatment for multiple cancer indications either as a monotherapy or in combination with leading checkpoint inhibitors; with the latter potentially enabling OncoSec to address a great unmet medical need in oncology: anti-PD-1 non-responders.?Results from recently completed clinical studies of TAVO(TM) have demonstrated a local immune response, and subsequently, a systemic effect as either a monotherapy or combination treatment approach along with an acceptable safety profile, warranting further development. In addition to TAVO(TM), OncoSec is identifying and developing new DNA-encoded therapeutic candidates and tumor indications for use with its new Visceral Lesion Applicator (VLA), to target deep visceral lesions, such as liver, lung or pancreatic lesions.
