NEW YORK, October 9, 2020 – Bragar Eagel & Squire, P.C., a nationally recognized shareholder rights law firm, is investigating potential claims against Y-mAbs Therapeutics, Inc. (NASDAQ: YMAB) on behalf of Y-mAbs stockholders. Our investigation concerns whether Y-mAbs has violated the federal securities laws and/or engaged in other unlawful business practices.

On October 5, 2020, Y-mAbs issued a press release disclosing receipt of “a Refusal to File letter from the U.S. Food and Drug Administration (‘FDA’) regarding the Biologics License Application (‘BLA’) for omburtamab for the treatment of pediatric patients with CNS/leptomeningeal metastasis from neuroblastoma, which was submitted in August 2020.”

Y-mAbs advised investors that “[u]pon preliminary review, the FDA determined that certain parts of the Chemistry, Manufacturing and Control (‘CMC’) module and the Clinical module of the BLA require further detail.”

On this news, y-mAbs’s stock price fell $3.57 per share, or 8.56%, to close at $38.13 per share on October 6, 2020.
