A Study of Tadalafil in Men With Benign Prostatic Hyperplasia Symptoms Who Are Being Treated With Alpha Blockers

A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Parallel-Design Study to Evaluate the Safety and Efficacy of Daily Tadalafil for 12 Weeks in Men With Signs and Symptoms of Benign Prostatic Hyperplasia on Concomitant Alpha1-Adrenergic Blocker Therapy

The purpose of this study is to evaluate the safety and efficacy of tadalafil when given to men who are currently taking a medication called an alpha blocker for the treatment of benign prostatic hyperplasia (BPH) symptoms (such as urinary frequency, urgency, and a feeling that the bladder is not completely emptied after urination).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Men With Treatment-emergent Dizziness	The primary safety measure is the proportion (reported in numbers) of subjects experiencing treatment-emergent dizziness to include the Medical Dictionary for Regulatory Activities (MedDRA) preferred terms of dizziness, dizziness postural, and procedural dizziness. Treatment-emergent dizziness is defined as any of the predefined terms of dizziness that is first reported or worsens in severity after baseline.	Baseline through 12 Weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Positive Orthostatic Vital Signs Test; Shift From Any Pre-Randomization to Any Post-Randomization Visit	A positive orthostatic test is defined as at least one of the following 4 criteria being met at any pre-randomization or post-randomization visit: (1) reduction in systolic blood pressure of >= 20 mmHg from the supine to standing position;(2)reduction in diastolic blood pressure of >=10 mmHg from the supine to standing position;(3)increase in heart rate of >= 20 bpm from the supine to standing position; or (4)Unable to remain standing. A negative orthostatic test is defined as none of the above 4 criteria (1, 2, 3, or 4) being met at any pre-randomization or post-randomization visit.	Baseline through 12 Weeks
International Prostate Symptom Score (IPSS) Change From Baseline	Change from baseline to endpoint in IPSS Score. The IPSS Total Score is obtained by combining the scores of the responses to 1 through 7 component questions. Each question is scored from 0-5 for an IPSS range of 0-35 points; higher numerical scores from the IPSS questionnaire represent greater severity of symptoms.	Baseline, 12 Weeks
Postvoid Residual Volume (PVR) Change From Baseline	Change from baseline to endpoint in PVR volume. PVR is obtained by measuring with ultrasound the remaining urine in the bladder after urination.	Baseline, 12 Weeks
Uroflowmetry (Qmax) Change From Baseline	Change from baseline to endpoint in Qmax. Qmax is defined as the peak urine flow rate (measured in milliliters per second [mL/second] using standard calibrated flowmeter).	Baseline, 12 Weeks
