The Allegations: Robbins LLP is Investigating Allegations that Actinium Pharmaceuticals, Inc. (ATNM) Misled Investors Regarding FDA Approval of Iomab-B
According to the complaint, during the class period, defendants misled investors to believe there was a very high likelihood that the FDA would review and approve the Company’s Biologics License Application (“BLA”) for Iomab-B. The complaint alleges that defendants (i) repeatedly touted the Sierra Trial’s positive DCR data while downplaying the study’s failure to generate statistically significant or clinically meaningful Overall Survival data; and (ii) misled investors about the importance of the Sierra Trial’s poor Overall Survival data by claiming the FDA had blessed the design of the trial such that the lack of statistically significant or clinically meaningful OS data would not be a barrier to approval of the BLA.
On August 5, 2024, Actinium announced “the FDA has now determined that the analyses from the Sierra trial do not adequately support a BLA filing for Iomab-B and requires an additional clinical study.” On this new, the price of Actinium’s common stock fell $3.69, or approximately to 60%, to close at $2.48 on August 5, 2024.
