Vardenafil restores erectile function to normal range in men with erectile dysfunction.

INTRODUCTION: The ability of oral phosphodiesterase type 5 (PDE5) inhibitor therapy to restore erectile function to normal is an important attribute to men with erectile dysfunction (ED). AIM: To assess the ability of vardenafil to restore normal erectile function in men with general ED. METHODS: In two fixed-dose, parallel-group, double-blind, placebo-controlled, pivotal studies, patients received vardenafil (5, 10, or 20 mg) or placebo for 12/26 weeks. MAIN OUTCOME MEASURE: In this retrospective analysis, the percentage of patients "returning to normal" erectile function at week 12 (as defined by scores > or =26 on erectile function domain of International Index of Erectile Function [IIEF-EF]) was determined, with further stratification by baseline ED severity, etiology, age, and duration of ED. RESULTS: Vardenafil 5, 10, and 20 mg returned 32%, 43%, and 49% of patients, respectively, to normal erectile function after 12 weeks, compared with 10% of patients receiving placebo (P < 0.0001). Return to normal IIEF-EF domain scores was noted irrespective of severity, etiology, age, and duration of ED, and was observed even in challenging-to-treat subgroups. With vardenafil 20 mg, 39% of men with severe ED at baseline, 45-49% of men with ED of mixed or organic etiology, 35% of men aged > or =65 years, and 43% of men with ED of > or =3 years of duration returned to normal erectile function at week 12. Mean per-patient SEP3 (question 3 on the Sexual Encounter Profile) success rates in patients achieving IIEF-EF domain scores > or =26 ranged from 87% to 95%. CONCLUSION: Vardenafil improves the IIEF-EF domain score to the normal range in a substantial proportion of men with ED.

Vardenafil is effective and well-tolerated for treating erectile dysfunction in a broad population of men, irrespective of age.

OBJECTIVES: To assess the efficacy and safety of vardenafil in the treatment of erectile dysfunction (ED) in men of different age groups. PATIENTS AND METHODS: In a retrospective pooled subgroup analysis of randomized, double-blind, placebo-controlled studies, men from the general population with ED received either placebo or vardenafil 5, 10 or 20 mg over 12 weeks. Efficacy variables included the erectile function (EF) domain score from The International Index of Erectile Function, diary response rates to questions on vaginal penetration and maintenance of erection, and positive responses to the Global Assessment Question (GAQ) "Has the treatment you have been taking over the past 4 weeks improved your erections?'. The 1385 men were grouped by age (< 45, 45-64 and > or =65 years). RESULTS: At 12 weeks the EF domain scores approached 20 with vardenafil and 14 with placebo in men aged > or = 65 years (P < 0.03 vardenafil 5 mg vs placebo, P < 0.001 vardenafil 10 and 20 mg vs placebo). The corresponding scores were 22 and 14 in men aged 45-64 years and up to 24 and 16 in those aged <45 years (P < 0.03 vardenafil 5 mg vs placebo, P < 0.001 vardenafil 10 and 20 mg vs placebo). Vardenafil generated positive GAQ responses in approximately 71%, 76% and 85% of men aged <45, 45-64 and > or = 65 years (P < or = 0.001 vardenafil vs placebo). The corresponding placebo rates were 23%, 25% and 34%. The most common treatment-emergent adverse events were headache, rhinitis, flushing and dyspepsia, which were mild to moderate, transient and unrelated to age. CONCLUSION: Vardenafil is an effective and generally well-tolerated treatment for ED, irrespective of age.

Vardenafil, a new phosphodiesterase type 5 inhibitor, in the treatment of erectile dysfunction in men with diabetes: a multicenter double-blind placebo-controlled fixed-dose study.

OBJECTIVE: This study evaluated the efficacy and safety of vardenafil treatment for erectile dysfunction (ED) in men with diabetes. RESEARCH DESIGN AND METHODS: In this prospective multicenter double-blind placebo-controlled fixed-dose parallel-group phase III trial, 452 patients with diabetes (type 1 or type 2) and ED were randomized to take 10 or 20 mg vardenafil or placebo as needed for 12 weeks. Efficacy responses were assessed by International Index of Erectile Function domain scores, rates of vaginal penetration and successful intercourse, and a global assessment question (GAQ) about erection improvement during the previous 4 weeks. RESULTS: After 12 weeks of treatment, a dose-dependent (P = 0.02) improvement in erections was noted for the GAQ, with 57 and 72% of men taking 10 mg or 20 mg vardenafil, respectively, reporting improved erections, in contrast to 13% after taking placebo (P < 0.0001). For the erectile function domain, dose-dependent (P = 0.03) final scores for the 10- and 20-mg dose were 17.1 and 19.0 compared with 12.6 for placebo (P < 0.0001). Both vardenafil doses significantly enhanced the rates of successful penetration (P < 0.0001) and successful intercourse (P < 0.0001) compared with placebo. Vardenafil treatment was effective in increasing intercourse success rates at all levels of baseline ED severity, at each level of plasma HbA(1c), and for type 1 and 2 diabetes. Treatment-emergent adverse events were primarily mild to moderate headache (

Sustained efficacy and tolerability of vardenafil, a highly potent selective phosphodiesterase type 5 inhibitor, in men with erectile dysfunction: results of a randomized, double-blind, 26-week placebo-controlled pivotal trial.

The durability of key efficacy response parameters and safety of vardenafil was evaluated in a pivotal trial conducted in a broad population of men with erectile dysfunction (ED) in North America. In this randomized, double-blind, placebo-controlled, multicenter, fixed-dose, parallel-group, 6-month comparison study, men >18 years of age with ED for >6 months received 5-mg, 10-mg, and 20-mg doses of vardenafil as needed for up to 26 weeks. The primary efficacy variables were the International Index of Erectile Function (IIEF)-Erectile Function (EF) domain scores, and the Sexual Encounter Profile (SEP) mean per-patient success rates for penetration (SEP question 2) and maintenance of erections (SEP question 3). Safety data were also collected over time. Improvement in all primary efficacy variables was observed in all vardenafil groups versus placebo. These improvements occurred early and were either sustained or increased through week 26. Vardenafil in 10-mg and 20-mg doses was significantly superior to placebo at all time points for all efficacy variables (P <0.01), and all doses were superior to placebo at endpoint (P <0.001). Most treatment-emergent adverse events (headache, flushing, dyspepsia, and rhinitis) were mild or moderate in intensity, and incidence generally decreased over time. All 3 doses of vardenafil were superior to placebo across all primary efficacy variables and all study time points in a broad range of patients with ED, regardless of etiology or severity. Vardenafil was well tolerated. These results demonstrate that vardenafil provides sustained efficacy with reduced incidence of nuisance side effects over time.
