NEW YORK, March 15, 2023 /PRNewswire/ --

WHY: Rosen Law Firm, a global investor rights law firm, reminds purchasers of the securities of Y-mAbs Therapeutics, Inc. (NASDAQ: YMAB) between October 6, 2020 and October 28, 2022, both dates inclusive (the "Class Period"), of the important March 20, 2023 lead plaintiff deadline.

SO WHAT: If you purchased Y-mAbs securities you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.

WHAT TO DO NEXT: To join the Y-mAbs class action, go to https://rosenlegal.com/submit-form/?case_id=9496 or call Phillip Kim, Esq. toll-free at 866-767-3653 or email pkim@rosenlegal.com or cases@rosenlegal.com for information on the class action. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than March 20, 2023. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.

WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources or any meaningful peer recognition. Many of these firms do not actually handle securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered hundreds of millions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.

DETAILS OF THE CASE: According to the Complaint, the Company made false and misleading statements to the market. Y-mAbs repeatedly misled investors about its meetings with the FDA, claiming that it was making progress in demonstrating the effectiveness and efficacy of its drug candidate, omburtamab. What was unknown to investors was that the FDA had repeatedly advised Y-mAbs that the treatment of effect of omburtamab cannot be objectively established or quantified based on a comparison between Study 03-133 and an external cohort comprised of data from the Central German Childhood Cancer Registry (CGCCR) database because of substantial differences in the patient populations, and the absence of tumor response data, and that Study 101 was neither sufficiently advanced nor indicative of efficacy to justify approval. Further, Y-mAbs failed to advise investors that it had elected to submit the March 31, 2022 BLA prior to reaching agreement with the FDA on the content of the application. Based on these facts, the Company's public statements were false and materially misleading throughout the class period. When the market learned the truth about Y-mAbs, investors suffered damages.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
