Efficacy and safety of tadalafil 5 mg once daily in the treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia in men aged ≥75 years: integrated analyses of pooled data from multinational, randomized, placebo-controlled clinical studies
Abstract
OBJECTIVE: To assess efficacy and safety of tadalafil in men aged ≥75 years with lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH) and additional safety in men aged ≥75 years with erectile dysfunction (ED).
PATIENTS AND METHODS: We conducted an integrated analysis of 12 phase II-III randomized, double-blind and/or open-label extension studies to evaluate short-term (12-26 weeks) efficacy and short- and longer-term (42-52 weeks) safety in men aged <75 years vs men aged ≥75 years. All men received once-daily tadalafil 5 mg or placebo. The efficacy outcome was International Prostate Symptom Score (IPSS). Safety measurements included treatment-emergent adverse events (TEAEs), adverse events (AEs) leading to discontinuation, serious AEs (SAEs), and cardiovascular AEs. All analyses were intention-to-treat. Changes from baseline to efficacy endpoint and differences in changes between treatment groups were estimated as least-squares means using analysis of covariance models.
RESULTS: Change in the mean IPSS was significantly different in men aged <75 years vs those aged ≥75 years across tadalafil and placebo groups (treatment-by-age interaction P = 0.034). Tadalafil was not statistically significantly better than placebo in men aged ≥75 years, but effect size varied between studies. Maintenance of efficacy with tadalafil was observed across age groups. Short-term tadalafil safety findings for men aged <75 vs ≥75 years included: TEAEs (52 [33.8%] vs…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 75 participants or records.
