Levitra is used to treat erectile dysfunction. It has also been studied in benign prostatic hyperplasia and tinnitus. The clinical program covers these urology indications, with 17 completed trials and a total enrollment of 7,861 participants across randomized, double-blind, placebo-controlled studies.

Who makes Levitra?

Levitra is developed by Bayer AG, which trades on the OTC market under the ticker BAYRY. Bayer conducted the clinical development program for the drug, including the pivotal Phase 3 trials in erectile dysfunction and the Phase 2 study comparing once-daily and as-needed dosing.

What phase is Levitra in?

Levitra is in Phase 2 development based on the current pipeline listing, and it is investigational rather than approved in this program. All 17 listed trials are completed, with none currently active, and the studies span Phase 2 and Phase 3 across erectile dysfunction and related conditions.

What clinical trials is Levitra in?

Levitra has been studied in completed trials including NCT00786253, a Phase 2 study of once-daily versus as-needed vardenafil in erectile dysfunction, and Phase 3 trials NCT00682019, NCT00678704 in diabetes patients, and NCT00668109 in patients with diabetes, hypertension or hyperlipidemia. All 17 trials are completed with no active studies.

Is Levitra the same as vardenafil?

Yes, Levitra is the brand name for vardenafil, and it was also known during development as BAY38-9456. Vardenafil is a small molecule developed by Bayer AG, and the alternative names refer to the same drug studied across the erectile dysfunction, benign prostatic hyperplasia and tinnitus programs.

How many patients were enrolled in Levitra trials?

Levitra trials enrolled a total of 7,861 participants across 17 completed studies. The program used randomized, double-blind, placebo-controlled designs.
