A Study in Benign Prostatic Hyperplasia
27 mars 2013 mis à jour par: Eli Lilly and Company
A Randomized, Double Blind, Placebo-controlled Study to Evaluate the Effect of Tadalafil Once Daily for 8 Weeks on Prostatic Blood Flow and Perfusion Parameters in Men With Signs and Symptoms of Benign Prostatic Hyperplasia
The purpose of this trial is to evaluate the effect of tadalafil 5 milligrams (mg) daily for 8 weeks compared to placebo on prostatic blood perfusion in men with signs and symptoms of Benign Prostatic Hyperplasia (BPH), measured by resistive index (RI) in the prostate transition zone.

Change From Baseline to 8-Week Endpoint in Arterial Resistive Index (RI) in the Prostate Transition Zone
Délai: Baseline, Week 8
|
Arterial RI was a measure of vascular resistance using Doppler ultrasound.
RI was the ratio of (peak systolic velocity - end diastolic velocity)/peak systolic velocity, and increased as resistance to blood flow increased.
The least squares (LS) mean was estimated from a mixed-effects model with repeated measures (MMRM) that included fixed effects for treatment, region, visit, and treatment-by-visit interaction, baseline as a covariate, a random effect of participant within treatment, and an unstructured covariance matrix.

Change From Baseline to 4 and 8 Weeks in Arterial Resistive Index (RI) in the Prostate Peripheral Zone and Bladder Neck
Délai: Baseline, Week 4 and Week 8
|
Arterial RI was a measure of vascular resistance using Doppler ultrasound.
RI was the ratio of (peak systolic velocity - end diastolic velocity)/peak systolic velocity, and increased as resistance to flow increased.
The least squares (LS) mean was estimated from a mixed-effects model with repeated measures (MMRM) that included fixed effects for treatment, region, visit, and treatment-by-visit interaction, baseline as a covariate, a random effect of participant within treatment, and an unstructured covariance matrix.

Change From Baseline to 4 and 8 Weeks in Color Pixel Intensity (CPI) in the Prostate Transition Zone, Peripheral Zone, and Bladder Neck
Délai: Baseline, Week 4 and Week 8
|
CPI quantified blood flow in a pre-specified region of interest by using color Doppler imaging.
CPI was the mean color pixel intensity in the region of interest and scores could range from 0 to 160.
An increase in CPI reflected an increase in blood flow.
The least squares (LS) mean was estimated from a mixed-effects model with repeated measures (MMRM) that included fixed effects for treatment, region, visit, and treatment-by-visit interaction, baseline as a covariate, a random effect of participant within treatment, and an unstructured covariance matrix.
