In August 2018, naxitamab, which is an anti-GD2 monoclonal antibody, received Breakthrough Therapy Designation by the FDA, which facilitates frequent interactions with the FDA review team. The Rolling Review process allows Y-mAbs to submit individual portions of the BLA for review, rather than waiting until all portions are completed and submitted to the FDA for review. Upon potential approval, the Company intends to commercialize naxitamab in the U.S.

"We are excited to announce the initiation of the rolling BLA for naxitamab, a major milestone for Y-mAbs. Dr. Nai-Kong Cheung and his research team at Memorial Sloan Kettering Cancer Center ("MSK") started looking at immunotherapy more than three decades ago when he first studied the anti-GD2 target. Today, high-risk neuroblastoma patients are being treated with naxitamab worldwide in clinical trials addressing clear unmet medical needs of children waiting for new treatment options," said Thomas Gad, Founder, Chairman, President and Head of Business Development and Strategy.

Dr. Claus Moller, Chief Executive Officer further notes, "I am both proud and appreciative of the Y-mAbs team and our clinical investigators, who have helped to make this key milestone possible. We believe that this submission represents an important landmark for Y-mAbs and for neuroblastoma patients."

MSK has institutional financial interests with Y-mAbs in the form of equity and intellectual property interests through licensing agreements. Dr. Cheung is a founder of, holds equity interests in, and has intellectual property rights related to Y-mAbs.
