Benign Prostatic Hyperplasia (BPH) MedDRA version: 14.1
Level: PT
Classification code 10004446
Term: Benign prostatic hyperplasia
System Organ Class: 10038604 - Reproductive system and breast disorders
|
Intervention(s)
|
Trade Name: CIALIS Pharmaceutical Form: Film-coated tablet INN or Proposed INN: Tadalafil Concentration unit: mg milligram(s) Concentration number: 5- Pharmaceutical form of the placebo: Film-coated tablet Route of administration of the placebo: Oral use
|
Primary Outcome(s)
|
Main Objective: Evaluate the effect of tadalafil 5 mg once daily for 8 weeks compared with placebo on improving prostatic blood perfusion in men with signs and symptoms of BPH, also referred to as BPH-LUTS (lower urinary tract symptoms), as measured by arterial resistive index (RI) in the prostate transition zone
|
Primary end point(s): The primary endpoint, and basis for comparison between treatment groups, will be the change from baseline in prostatic transitional zone resistive index (RI) from baseline to Week 8
|
Secondary Objective: - To evaluate the effect of tadalafil 5 mg once daily for 8 weeks versus placebo on other regional blood flow and perfusion parameters in the prostate as measured by: Color Doppler ultrasound pixel intensity (color pixel intensity, CPI) in the prostate transition zone and arterial RI and CPI in prostate peripheral zone. - To evaluate the effect of tadalafil 5 mg once daily for 8 weeks versus placebo on blood flow and perfusion parameters in the bladder neck as measured by arterial RI and CPI. - To evaluate the effect of tadalafil 5 mg once daily for 4 weeks versus placebo on all of the above blood flow and perfusion parameters in the prostate and bladder neck
