"We are pleased to initiate a second clinical trial collaboration with Merck – one of the world’s leading immuno-oncology companies – in late stage TNBC, a disease which has few treatment options," said Daniel J. O’Connor, Chief Executive Officer of OncoSec. "This collaboration is another example of OncoSec’s strategy to work with innovative immuno-oncology leaders, combining 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 TNBC who have inoperable locally advanced or metastatic disease and progressed on at least one previous treatment of systemic chemotherapy or immunotherapy. Under the collaboration agreement, OncoSec will sponsor and fund the study and Merck will provide KEYTRUDA. Additional details of the collaboration were not disclosed.
