Armen is the chairman and CEO of Agenus Inc., a biotechnology company he co-founded in 1994, focused on immunotherapies to fight cancer. One of Agenus’ achievements is the development of the BOT/BAL combination therapy, which has demonstrated success in difficult-to-treat cancers, including metastatic colorectal cancer. This therapy reawakens the immune system’s natural ability to fight cancer, representing a significant advancement in the treatment of cancers that were once considered insurmountable.
Armen is also the chairman of Mink Therapeutics, which is developing novel cell therapies that modulate immune responses. These therapies aim to treat both cancer and a range of immune disorders, providing a new approach to managing complex diseases.
He also spearheaded the restructuring of Elan Corporation, guiding the company through a period that ultimately saved it from collapse. He also serves as the executive chairman of Protagenic Therapeutics, a company focused on therapies for neurological and metabolic disorders.
