"We are very pleased with the clearance of our IND application for our lead autologous CAR T product candidate, ONCT-808," said James Breitmeyer, M.D., Ph.D., Oncternal’s President and CEO. "This will be our second clinical program focusing on the important ROR1 cancer target, following the initiation of our phase 3 study for our ROR1 antibody zilovertamab, announced last week. ROR1 is an exciting and promising target that is highly expressed in a wide range of cancers and is an ideal candidate for cell therapy applications due to its highly specific tumor expression, and association with tumor survival mechanisms. Our initial dose finding study will enroll patients with aggressive B NHL, including those that have failed prior CD19 therapy, which represent a significant unmet need in the market today. We expect to initiate the study in the coming months and to present interim results at a scientific conference in 2023."
