Y-mAbs recently concluded a Type B meeting with the U.S. Food and Drug Administration ("FDA") regarding omburtamab and received requests from the FDA for additional data concerning the granularity of data from our identified historical control groups. In order to agree on a statistical analysis plan ("SAP"), this additional granularity data is being collected and we anticipate submitting it to the FDA by the end of April. An additional Type B meeting has been scheduled for June 1, 2021 to discuss the SAP based on review of the additional data. We continue to be in close dialog with the FDA and maintain our aim of resubmitting the Biologics License Application ("BLA") for omburtamab late in the second quarter or in the third quarter of 2021.
"We believe omburtamab is on track to potentially become the first FDA approved targeted therapy for pediatric patients with CNS/leptomeningeal metastasis from neuroblastoma, addressing an important unmet medical need, where no standard therapy is currently available," said Thomas Gad, founder, Chairman and President of Y-mAbs.
Dr. Claus Moller, the Company’s Chief Executive Officer, continued, "We believe omburtamab can potentially address a significant unmet medical need for children with CNS/leptomeningeal metastasis from neuroblastoma, and we continue to work closely with the FDA to resubmit the omburtamab BLA. In addition, we are targeting submission of a Marketing Authorization Application to the European Medicines Agency on April 30, 2021."
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 interest related to the compound and Y-mAbs.
