Bayer Corporation has submitted a New Drug Application (NDA) for vardenafil, an investigational compound for the improvement of erectile function, to the U.S. Food and Drug Administration (FDA).
Simultaneously, Bayer submitted vardenafil for regulatory review in Mexico.
"Current estimates suggest more than half of all men over the age of 40 experience some level of erectile dysfunction," said Irwin Goldstein, M.D., professor of urology at Boston University School of Medicine and a vardenafil investigator. "Erectile dysfunction is a complex medical condition for which physicians and patients are in need of new treatment options."
Erectile dysfunction (ED) -- the inability to sustain an erection sufficient for sexual intercourse -- is a medical condition that affects an estimated 30 million men in the U.S., but research shows only an estimated 11 percent are being treated. There are a number of causes for ED, including diabetes, cardiovascular disease, and medications such as antidepressants.
"The vardenafil NDA submission includes data from a variety of patient populations ranging from mild to the more difficult-to-treat patients, such as those with diabetes," said David R. Ebsworth, Ph.D., president and general manager, Business Group Pharma, Bayer AG. "This milestone represents an impressive 47-month development period from the beginning of preclinical testing to NDA submission. Pending FDA approval, Bayer hopes to launch vardenafil in the second half of 2002."
