| EWING, N.J. and SAN DIEGO, May 16, 2023 /PRNewswire/ -- OncoSec Medical Inc. (NASDAQ: ONCS) (the Company or OncoSec), a clinical-stage biotechnology company developing intratumoral immunotherapies to stimulate the patient’s immune system to target cancer cells and eradicate disease, today announced a Type C meeting held with the US Food and Drug Administration (FDA) on May 15, 2023. The purpose of the meeting was to discuss the trial design for a planned randomized, open-label Phase 2 clinical trial in patients with high-risk, resectable melanoma to evaluate the neoadjuvant treatment combination of the Company’s tavokinogene telseplasmid, a plasmid encoding human interleukin 12 (IL-12), administered intratumorally by electroporation (TAVO™-EP) with intravenous KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy. The meeting with the FDA represents an important next step on the Company’s path to pursue clinical development of TAVO™-EP in combination with anti-PD-1 therapy in the neoadjuvant melanoma setting. The Company discussed with the FDA the proposed design of a global randomized Phase 2 trial, which includes a primary endpoint of pathological complete response (pCR) rate and secondary endpoints including event-free survival (EFS) and pathological major response (pMR) rate. As discussed with the FDA, a single arm run-in stage is planned to confirm the appropriate neoadjuvant dosing schedule and allow the collection of mechanistic biomarker data to further evaluate the mechanism of action of TAVO™-EP as a trigger for anti-tumor immune effector functions. In the randomized stage, neoadjuvant treatment with TAVO™-EP in combination with pembrolizumab will be compared to pembrolizumab alone. The rationale for the proposed trial is an evolving standard of care in neoadjuvant melanoma treatment. Recently published results from neoadjuvant trials have demonstrated the potential for neoadjuvant immunotherapy to improve long-term clinical benefits to patients, including a randomized Phase 2 trial (SWOG S1801) in 313 patients that demonstrated statistically significant improved EFS for neoadjuvant versus adjuvant pembrolizumab. The Company’s discussion with the FDA follows the release of interim data from an ongoing investigator-sponsored trial (IST) led by Dr. Ahmad Tarhini at the H. Lee Moffit Cancer Center & Research Institute evaluating TAVO™-EP in combination with intravenous nivolumab, which showed encouraging clinical and pathological response rates (see press release on November 15, 2022). Preliminary data from this IST have also shown that several patients, predicted by biomarker analysis to be non-responders to immune checkpoint inhibitors, experienced clinical and pathological responses to TAVO™-EP in combination with nivolumab. Generating additional data in the randomized Phase 2 trial is intended to further delineate the mechanism of action of intratumoral IL-12 in combination with intravenous anti-PD-1 antibodies in a larger sample size. The Company appreciates the productive meeting with the FDA and the agency’s feedback on the trial design and potential strategies for future registrational paths. To allow data driven decisions in an evolving therapeutic landscape in neoadjuvant melanoma, the Company expects to engage in continued communication with the FDA and other applicable global regulatory agencies for feedback regarding an efficient development path to registration of TAVO™-EP in combination with pembrolizumab in neoadjuvant melanoma. “Melanoma patients require more effective treatment approaches early in the disease to avoid disease progression to late-stage disease. By providing a stimulus of immune effector functions, TAVO™-EP in combination with immune checkpoint inhibitors is expected to offer a differentiated therapeutic approach compared to immune checkpoint inhibitors alone as discussed in our recent corporate update in April 2023. The unmet clinical need in advanced melanoma together with previously reported interim results from Dr. Tarhini’s IST in the neoadjuvant melanoma setting provide sound rationale for further development of TAVO™-EP in combination with anti-PD-1 therapy prior to surgery. We are encouraged by our discussions with the FDA and the agency’s constructive feedback after the review of our draft protocol for TAVO™-EP in combination with pembrolizumab for a randomized Phase 2 trial in the neoadjuvant setting and are looking forward to potentially initiating the trial before the end of 2023,” said Robert Arch, Ph.D., Chief Executive Officer of OncoSec. “The single-arm run-in stage of the trial is intended to generate additional data in a cost-effective manner to inform a ‘GO/NO-GO’ decision and validate the appropriate dosing schedule for the randomized phase in the first year of the planned trial. I want to thank all patients who have participated in our clinical trials and my colleagues at OncoSec who seek to develop this novel therapeutic treatment approach designed to awaken the immune system to fight cancer.” About OncoSec Medical Incorporated TAVO™ is a trademark of OncoSec Medical Incorporated.
