Y-mAbs Therapeutics, Inc. (NASDAQ:YMAB) Securities Fraud Class Action:

The litigation focuses on Y-mAbs' past assurances that its Biologics License Application ("BLA") for I-omburtamab for the treatment of central nervous system/leptomeningeal metastases in pediatric patients with neuroblastoma was "on track."

The complaint alleges that Defendants assured investors that, pursuant to a series of meetings and other communications between Y-mAbs and the FDA, progress was being made toward meeting the FDA's requirement that the company demonstrate substantial evidence of effectiveness for FDA approval of omburtamab. The complaint further alleges that Defendants did not disclose that: (1) the FDA repeatedly advised the company that effectiveness of omburtamab could not be objectively established based on a comparison of its study to an external cohort comprised of data from the Central German Childhood Cancer Registry ("CGCCR"); and (2) the company's Study 101 was neither sufficiently advanced nor indicative of efficacy to justify FDA approval.

Investors learned the truth on Oct. 26, 2022, when the FDA Oncologic Drugs Advisory Committee ("ODAC") published its briefing document which identified FDA scientists' concerns about the totality of evidence submitted by Y-mAbs in support of its BLA. Among other things, the briefing document revealed that the FDA informed Y-mAbs on multiple occasions that the CGCCR data external control may not be fit-for-purpose as a direct comparator for overall survival data.

Then, on Oct. 28, 2022, Y-mAbs announced that ODAC unanimously voted that the company did not provide sufficient evidence to conclude that omburtamab improves overall survival.

These events sent the price of Y-mAbs shares crashing lower.

"We're focused on investors' losses and proving Y-mAbs lied about data submitted in support of its BLA, its communications with the FDA, and the commercial prospects for I-omburtamab," said Reed Kathrein, the Hagens Berman partner leading the investigation.
