On November 8, 2017 OncoSec Medical Incorporated ("OncoSec" or "Company") (NASDAQ:ONCS), a company developing DNA-based intratumoral cancer immunotherapies, reported positive updated long-term follow-up data from its Phase 2 OMS I-102 combination study of ImmunoPulse IL-12 and pembrolizumab in patients unlikely to respond to anti-PD-1 therapy (Press release, OncoSec Medical, NOV 8, 2017, View Source [SID1234521755]). The updated data will be presented in an oral poster presentation (P524) by Dr. Alain Alagzi at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Annual Meeting in National Harbor, MD on November 10th, 2017 at 12:45 p.m. EST.

The updated clinical and correlative immune-focused biomarker data demonstrated a 57% progression free survival (PFS) rate at 15 months with 100% (11/11) duration of response and median PFS not yet reached. Building upon previously reported data of a best overall response rate (BORR) of 50% (41% complete response [CR] rate), the updated data further demonstrate that the combination of these therapies can prime a coordinated innate and adaptive immune response, and strongly suggests a synergistic relationship with anti-PD-1. The latest findings further demonstrate that this combination approach can reshape the tumor microenvironment, yielding a robust intratumoral and systemic anti-tumor response converting "cold" tumors to "hot," potentially improving clinical outcomes in patients predicted to not respond to anti-PD-1 therapy.

"Overall, the Phase 2 trial results, including progression free survival beyond two years in multiple patients, duration of response, best overall response rate, and tolerability of the combination, provide a strong and consistent theme across multiple endpoints, underscoring the promise of ImmunoPulse IL-12 plus pembrolizumab as a viable treatment option for patients diagnosed with metastatic melanoma," said Dr. Alain Algazi, Lead Trial Investigator, Associate Professor, Department of Medicine (Hematology/Oncology), at the University of California San Francisco (UCSF) Helen Diller Family Comprehensive Cancer Center.

Dan O’Connor, CEO of OncoSec noted: "The robust PFS benefit and tolerability observed with ImmunoPulse IL-12 plus pembrolizumab is the first demonstrating efficacy in a predicted PD-1 non-responder population and shows that the combination represents a potentially important addition to the treatment landscape for metastatic melanoma patients who have progressed or are progressing on anti-PD-1 therapy."

Peer-Reviewed Publication

The findings published in Immunotherapy provide an overview of OncoSec’s preclinical and Phase 1 clinical data demonstrating that ImmunoPulse IL-12 plus electroporation is safe and well-tolerated by patients. Many patients do not respond to anti-PD-1 therapies alone, representing a significant unmet medical need. ImmunoPulse IL-12 has shown to increase intratumoral lymphocyte infiltration, pro-inflammatory cytokines and TH1 immune responses, potentially boosting the activity of PD-1 antibodies without significant systemic toxicity.

About PISCES/KEYNOTE-695

PISCES/KEYNOTE-695 is a global, multicenter phase 2b, open-label trial of intratumoral plasma encoded IL-12 (tavokinogene telseplasmid or "tavo") delivered by electroporation in combination with intravenous pembrolizumab in patients with stage III/IV melanoma who have progressed or are progressing on either pembrolizumab or nivolumab treatment. The Simon 2-stage study of intratumoral tavo plus electroporation in combination with pembrolizumab will enroll approximately 48 patients with histological diagnosis of melanoma with progressive locally advanced or metastatic disease defined as Stage III or Stage IV. The primary endpoint will be the Best Overall Response Rate (BORR).
