Vasogen is a leader in the research and commercial development of immune modulation therapies targeting the chronic inflammation underlying cardiovascular disorders. Vasogen’s lead product, Celacade™ (immune modulation therapy) is currently in phase 3 clinical trials for the treatment of chronic heart failure and peripheral arterial disease. Celacade™ is designed to target chronic inflammation by activating the immune system’s physiological anti-inflammatory response to apoptotic cells. Celacade™ up-regulates the expression of cell surface molecules that interact with specific receptors on antigen presenting cells (APCs) to modulate the production of cytokines – potent chemical messengers that initiate and control inflammation. Vasogen is also developing a new class of phospholipid-based drugs designed to interact with APCs to regulate cytokine levels and control inflammation in the nervous system, including the brain. VP025, the first product candidate from this new class of drugs, is in preclinical development for the treatment of neuro-inflammatory disorders.
