According to the filed complaint, on May 22, 2023, the Company announced that milademetan failed to meet its primary endpoint of progression free survival in the MANTRA study. Moreover, the Company announced adverse event findings that, according to analysts, indicated that the dosing schedule had not been optimized prior to commencing the study. In response to the announcement, Rain’s stock price substantially dropped from $9.93 per share to $1.22 per share, eliminating approximately $316 million in market capitalization in one day. The complaint alleges that defendants made false and/or misleading statements and/or failed to disclose that: (i) the Company concealed risks inherent in the design of its Phase 3 MANTRA study particularly with regard to proceeding directly to Phase 3 from Phase 1; and, (ii) as a result, the Company’s statements about the trial and the likelihood of FDA approval were materially misleading during the Class Period.
