Proportion of tadalafil-treated patients with clinically meaningful improvement in lower urinary tract symptoms associated with benign prostatic hyperplasia – integrated data from 1,499 study participants.

Abstract:

OBJECTIVES:To evaluate the proportion of patients achieving clinically meaningful improvement of lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH-LUTS) with tadalafil using two definitions of response. PATIENTS AND METHODS:Post hoc integrated analysis of four placebo-controlled studies in men (aged ≥45 years; International Prostate Symptom Score [IPSS] of ≥13; maximum urinary flow rate [Q(max)] of ≥4 to ≤15 mL/s) with BPH-LUTS randomised to tadalafil 5 mg (752 patients) or placebo (747) for 12 weeks after a 4-week placebo run-in. Responders were defined as having a total IPSS improvement of ≥3 points or ≥25% from randomisation to endpoint (Week 12). Response status was calculated per patient, and relative benefit and odds ratio (OR) with 95% confidence interval (CI) of tadalafil vs placebo was calculated using a logistic Generalised Mixed Model for Repeated Measures. RESULTS:Tadalafil 5 mg once daily resulted in a significantly greater proportion of patients achieving a ≥3-point IPSS improvement (71.1% and 56.0% for tadalafil and placebo patients, respectively [OR 1.9, 95% CI 1.5, 2.4; P < 0.001]) and achieving a ≥25% improvement in total IPSS randomisation to endpoint (61.7% and 45.5% for tadalafil and placebo patients, respectively [OR 2.0, 95% CI 1.6, 2.5; P < 0.001]). CONCLUSION:About two-thirds of tadalafil-treated patients achieve a clinically meaningful improvement in BPH-LUTS symptoms, based on two different definitions of responder status.
