"We are very encouraged by the DSMB’s seventh consecutive positive recommendation to continue BriaCell’s pivotal Phase 3 Bria-ABC study," said Dr. William V. Williams, President and Chief Executive Officer of BriaCell. "This milestone represents continued progress in developing BriaCell’s novel immunotherapies for patients with urgent unmet medical needs."
