Over one million people in the United States are diagnosed with an abdominal aortic aneurysm (AAA), and this number continues to grow as the population ages. It is likely that there is a large number of undiagnosed cases, bringing the number of afflicted Americans to almost three million. Currently there exist no effective drug therapies for large AAAs, leaving surgery as the only option for many. BSN908 has proven effective in animal studies, reducing both AAA formation and severity in lab animals.
