- Number of Men With Treatment-emergent Dizziness [ Time Frame: Baseline through 12 Weeks ]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.
- Number of Participants With Positive Orthostatic Vital Signs Test; Shift From Any Pre-Randomization to Any Post-Randomization Visit [ Time Frame: Baseline through 12 Weeks ]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.
- International Prostate Symptom Score (IPSS) Change From Baseline [ Time Frame: Baseline, 12 Weeks ]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.
- Postvoid Residual Volume (PVR) Change From Baseline [ Time Frame: Baseline, 12 Weeks ]Change from baseline to endpoint in PVR volume. PVR is obtained by measuring with ultrasound the remaining urine in the bladder after urination.
- Uroflowmetry (Qmax) Change From Baseline [ Time Frame: Baseline, 12 Weeks ]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).
