OncoSec Announces Clinical Collaboration with Merck to Evaluate Combination of ImmunoPulse® IL-12 and KEYTRUDA® (pembrolizumab) for Metastatic Melanoma

SAN DIEGO, May 10, 2017 /PRNewswire/ -- OncoSec Medical Incorporated ("OncoSec") (NASDAQ: ONCS), a company developing DNA-based intratumoral cancer immunotherapies, has entered a clinical trial collaboration and supply agreement with Merck (known as MSD outside the United States and Canada) to evaluate the combination of OncoSec's ImmuoPulse® IL-12 with Merck's anti-PD-1 therapy KEYTRUDA® (pembrolizumab) in a Phase II clinical trial, referred to as PISCES. The planned clinical trial will evaluate the safety and efficacy of the combination in patients with metastatic melanoma following disease progression on previous treatment with an anti-PD-1 therapy.

"We are honored to collaborate with Merck – one of the world's leading cancer immuno-oncology companies – to help bring innovative cancer treatments to patients with unmet medical needs," said Punit Dhillon, CEO and President of OncoSec. "This collaboration is supported by our recent clinical data demonstrating the potential ability of ImmunoPulse^® IL-12 to rescue patients who do not initially respond to anti-PD-1 therapy in melanoma. In addition to our recent Fast Track Designation for this population, OncoSec is uniquely positioned to meaningfully impact clinical outcomes for patients who do not currently have any other options. By working with innovative immuno-oncology leaders, this alliance underpins OncoSec's strategy to combine our ImmunoPulse^® IL-12 program with checkpoint inhibitor therapies to advance the care of patients."

Eligible patients for this Phase II study will be those with Stage III/IV metastatic melanoma who are progressing, or have progressed, on previous treatment with an anti-PD-1 therapy. The collaboration agreement is between OncoSec Medical Incorporated and Merck, through a subsidiary. Under the agreement, OncoSec will sponsor and fund the study and Merck will provide KEYTRUDA®. Additional details of the collaboration were not disclosed.
