Celanese Corporation (NYSE: CE), a global specialty materials and chemical company, and Alessa Therapeutics announced their collaboration for developing a new oncology drug product leveraging Alessa’s expertise on sustained localized drug delivery and the Celanese VitalDose^® EVA drug delivery platform. The collaboration will focus on developing a localized and sustained-release drug delivery system for oncology patients that will limit systemic side effects and improve overall treatment.
