Highlights from the Investor & Analyst Day
Tara C. Mitchell, M.D., Associate Professor of Medicine at Penn Medicine, who exclusively treats patients with melanoma, provided her clinical impressions of the KEYNOTE-695 data and the PD-1 checkpoint refractory patient population. Dr. Mitchell stated, "Patients are eager to have this type of option, with an excellent safety profile and durable efficacy. I see this treatment as promising and look forward to offering it to patients who have progressed on PD-1 blockade and to seeing ongoing study results from this combination."
Dr. Mitchell also commented:
Matteo Carlino, M.D., Medical Oncologist and Clinical Senior Lecturer at Westmead and Blacktown Hospitals and University of Sydney, and one of the KEYNOTE-695 trial investigators, commented, "I'm confident that the KEYNOTE-695 data will remain positive and now that we have completed enrollment of 100 patients, we expect to continue to see deepened responses over time. Since a number of patients with stable disease over several months have become responders with continued treatment, we believe the data has the potential to improve over time."
Dr. Carlino also provided his perspective on other therapeutic approaches in the checkpoint refractory metastatic melanoma patient population and where the TAVO plus KEYTRUDA combination fits in the field:
Additional topics covered included OncoSec's CORVax12 vaccine, the Company's novel DNA-encodable vaccine that combines TAVO with the National Institute of Health (NIH)/ National Institute of Allergy and Infectious Diseases (NIAID) Vaccine Research Center's SARS-CoV-2 virus "spike" protein. OncoSec is developing CORVax12 in collaboration with Portland Providence Medical Center and the vaccine candidate is expected to enter a Phase 1 clinical trial shortly, after the recent acceptance of an Investigational New Drug application.
Bernard Fox, Ph.D., Harder Family Chair for Cancer Research, Chief of the Laboratory of Molecular Tumor Immunology at Earle A. Chiles Research Institute, said, "By combining the immune stimulant IL-12, we aim to augment the vaccine response to produce more durable neutralizing antibodies. This approach is relevant particularly for the most vulnerable populations, such as the elderly, patients with immunodeficiencies or immunocompromised cancer patients. We look forward to seeing if IL-12 can help these patients boost their immune system against the virus."
Experts also shared insights about OncoSec's new neoadjuvant melanoma clinical trial and opinions on the VLA program, looking to the future of gene electrotransfer in both lung and liver tumors.

KEYNOTE-695 is OncoSec's registration-directed Phase 2b trial (NCT#03132675) evaluating TAVO™ (tavokinogene telseplasmid), a DNA plasmid-based interleukin-12 (IL-12) + KEYTRUDA® (pembrolizumab) in patients with rigorously confirmed anti-PD-1 checkpoint resistant metastatic melanoma. The trial aims to enroll up to 100 patients with refractory, locally advanced or metastatic disease defined as unresectable Stage III/IV metastatic melanoma that had definitively progressed on a full-course of anti-PD-1 treatment with KEYTRUDA® (pembrolizumab) or OPDIVO® (nivolumab). TAVO™ has received Fast Track Designation from the U.S. Food and Drug Administration (FDA) for the treatment of metastatic melanoma following progression on KEYTRUDA or OPDIVO.
OncoSec's gene therapy technology combines TAVO™ (tavokinogene telseplasmid), a DNA plasmid-based interleukin-12 (IL-12), with an intratumoral electroporation gene delivery platform to achieve endogenous IL-12 production in the tumor microenvironment that enables the immune system to target and attack tumors throughout the body. TAVO™ has demonstrated a local and systemic anti-tumor response in several clinical trials, including the pivotal Phase 2b trial KEYNOTE-695 for metastatic melanoma and the KEYNOTE-890 Phase 2 trial in triple negative breast cancer (TNBC). TAVO™ has received Orphan Drug and Fast-Track Designation by the U.S. Food & Drug Administration (FDA) for the treatment of metastatic melanoma following progression on KEYTRUDA or OPDIVO.
CORVax12 is the only known DNA vaccine that uses an immune stimulant to promote an immune response against the SARS-CoV-2 virus. The CORVax12 vaccine approach combines the co-administration of a DNA-encodable version of the stabilized SARS-CoV-2 spike or "S" glycoprotein trimer with TAVO™ (plasmid IL-12) to enhance the immunogenicity of this vaccine developed by scientists at the National Institute of Allergy and Infectious Diseases (NIAID) Vaccine Research Center. CORVax12 is designed to drive a coordinated vaccine response, capable of drawing upon the innate and adaptive humoral and cellular arms. This multi-pronged immune response has the potential to generate a robust and durable anti-viral response.
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™ (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™ 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™ 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™, 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.
