On June 30, 2020 Y-mAbs Therapeutics, Inc. (the "Company" or "Y-mAbs") (Nasdaq: YMAB) a late-stage clinical biopharmaceutical company focused on the development and commercialization of novel, antibody-based therapeutic products for the treatment of cancer, reported that the Company has initiated the submission of its Biologics License Application ("BLA") for omburtamab under the U.S. Food and Drug Administration’s ("FDA") Rolling Review process. Omburtamab is an investigational, monoclonal antibody that targets B7-H3, an immune checkpoint molecule that is widely expressed in tumor cells of several cancer types (Press release, Y-mAbs Therapeutics, JUN 30, 2020, View Source [SID1234561600]). The omburtamab BLA is for the treatment of pediatric patients with CNS/leptomeningeal metastases from neuroblastoma.

The non-clinical portion and a part of the CMC portion of the rolling BLA were submitted during June 2020, and completion of the BLA submission is currently expected to take place over the next four to six weeks. The clinical submission will be based on the safety and efficacy results of the pivotal Phase 2 studies 101 and 03-133, which the Company expects to present later this year.
"As the father of a long-term high-risk neuroblastoma survivor with CNS/Leptomeningel metastasis, I know how important this potentially is for families faced with brain metastasis from high-risk neuroblastoma and I am excited to see the initiation of Y-mAbs’ second BLA submission this year in neuroblastoma. We believe this is a key milestone for families facing CNS/leptomeningeal metastases from neuroblastoma and for Y-mAbs. We are very grateful to all clinical sites involved in developing omburtamab, and especially to our employees in the development team." stated Thomas Gad, Founder, Chairman and President.
Dr. Claus Moller, Chief Executive Officer, continued, "We look forward to working with the Agency to bring omburtamab to appropriate patients. We believe omburtamab can potentially address a significant unmet medical need for children with CNS/leptomeningeal metastases from neuroblastoma."
Researchers at Memorial Sloan Kettering Cancer Center ("MSK") developed omburtamab, which is exclusively licensed by MSK to Y-mAbs. As a result of this licensing arrangement, MSK has institutional financial interests related to the compound and Y-mAbs.
