I get the impression that CytoDyn thinks that they have a case against Amarex.

"The decision to voluntarily withdraw was based on various factors, including systemic issues related to the quality of the data collection and monitoring of the pivotal clinical trials by the clinical research organization (CRO) contracted to manage the trials, resulting in significant concerns with achieving a successful U.S. Food and Drug Administration (FDA) BLA approval. The Company is of the opinion that FDA approval for the HIV-MDR indication is not feasible without significant additional investment to remedy the issues"
