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. 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 lawsuit, defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose material adverse facts about the Company's business operations and prospects. Specifically, defendants made false and/or misleading statements and/or failed to disclose that: (1) lenzilumab was less effective in treating hospitalized COVID-19 patients than defendants had represented; (2) as a result, the U.S. Food and Drug Administration (“FDA”) was unlikely to approve the lenzilumab Emergency Use Authorization (“EUA”) and the ACTIV-5/BET-B study was unlikely to meet its primary endpoint; (3) accordingly, lenzilumab’s clinical and commercial prospects were overstated; and (4) as a result, the Company’s public statements were materially false and misleading at all relevant times. When the true details entered the market, the lawsuit claims that 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.
