Trial Outcomes & Findings for Multinational Study to Evaluate Tadalafil in Asian Men With Signs and Symptoms of Benign Prostatic Hyperplasia (NCT NCT00861757)

NCT ID: NCT00861757

Last Updated: 2011-06-28

Results Overview

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. Least Squares Mean values were controlled for prior alpha blocker use (yes/no), country (Japan/Korea/Taiwan) and baseline value.

PRIMARY outcome

Timeframe: baseline, 12 weeks

Population: The primary analysis population for efficacy included all subjects who were randomized and started study medication. All efficacy analyses were performed on an intent-to-treat (ITT) basis.

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. Least Squares Mean values were controlled for prior alpha blocker use (yes/no), country (Japan/Korea/Taiwan) and baseline value.

IPSS obstructive subscore is the sum of Questions 1, 3, 5 and 6 of the IPSS questionnaire. Scores range from 0 (few obstructive symptoms) to 5 (frequent obstructive symptoms); 4 questions of the obstructive score range from 0 to 20. IPSS irritative subscore is the sum of Questions 2, 4 and 7 of IPSS questionnaire. Scores range from 0 (no irritative symptoms) to 5 (frequent irritative symptoms); 3 questions of the irritative subscore range from 0 to 15. Least Squares Mean values were controlled for prior alpha blocker use (yes/no), country (Japan/Korea/Taiwan), and baseline value.

The BII is a 4-item, self-administered questionnaire evaluating impact of urinary problems on overall health and activity. Total scores range from 0 to 13; higher scores represent increased perceived impact of benign prostatic hyperplasia-lower urinary tract symptoms on overall health. Least Squares Mean values were controlled for BPH severity (moderate/severe), prior alpha blocker use (yes/no), country (Japan/Korea/Taiwan) and baseline value.

The PGI-I measures the patient's perception of improvement at the time of assessment compared with the start of treatment. There are 7 categories with scores ranging from 1 (very much better) to 7 (very much worse). The data are presented as the number of participants in each of the 7 categories: very much better (1); much better (2); a little better (3); no change (4); a little worse (5); much worse (6); very much worse (7).
