Y-mAbs Submitting Omburtamab Data Sought by FDA
Y-mAbs Therapeutics says it is collecting data from identified historical control groups sought by FDA for the company’s omburtamab, an investigational monoclonal antibody that targets B7-H3 and has been radiolabeled before intraventricular central nervous system administration. A company statement says the firm had a Type B meeting with the agency at which FDA requested the additional data concerning the granularity of data from the control groups.
Y-mAbs says it anticipates submitting the requested data before the end of April and has another Type B meeting set for 6/1 to discuss the statistical analysis plan based on the review of the additional data. It says it continues to project submission of a BLA for omburtamab late in the second quarter or the third quarter of this year.
Company officials say they believe the drug is on track to potentially become the first FDA-approved targeted therapy for pediatric patients with central nervous system/leptomeningeal metastasis from neuroblastoma.
