This study has been completed.
Information provided by:
Sanofi Identifier:
First received: June 14, 2007
Last updated: September 29, 2009
Last verified: September 2009

Primary Objective:

  • To assess the sexual function improvement from baseline to the end of treatment (Week 24 or premature withdrawal (PW)) with XATRAL 10mg OD.

Secondary Objective:

  • To evaluate the association between Lower Urinary Tract Symptoms (LUTS) severity and sexual disorders,
  • To compare the improvement in sexual function, urinary symptoms and Quality of Life among the different regions,
  • To correlate MSHQ (Male Sexual Health Questionnaire) and IIEF-5 (the 5-Item version of the International Index of Erectile Function),
  • To assess the onset of action of XATRAL 10mg OD,
  • To assess the peak flow rate improvement (Qmax),
  • To assess the safety and the tolerability of XATRAL 10mg OD.

Further study details as provided by Sanofi:

Primary Outcome Measures:
  • Mean change from baseline to the end of treatment in the Male Sexual Health Questionnaire(MSHQ) for sexual function. [ Time Frame: 24 weeks ]
  • Evaluation of adverse events, vital signs (blood pressure and heart rate), PSA (Prostate-specific antigen; mandatory at baseline and optional at the end of treatment) and serum creatinine assessment (optional at baseline and at the end of treatment) [ Time Frame: 24 weeks ]

Secondary Outcome Measures:
  • - Mean change from baseline to 4, 12, and 24 weeks of treatment in MSHQ in the ejaculation score - Mean change from baseline to 4, 12 and 24 weeks of treatment in MSHQ ejaculation questions, in the erection questions and sexual activity and desire [ Time Frame: 24 weeks ]
  • - Mean change from baseline to week 1 in I-PSS total score and sub-scores (objective onset of action) - Onset of action based on patient perception (questionnaire at Week 1) [ Time Frame: 24 weeks ]
  • -Mean change from baseline to 4,12 and 24 weeks of treatment in the I-PSS total score and in the Quality of Life -QOL Mean change from baseline to 4, 12 and 24 weeks of treatment in the I-PSS total score and in the Quality of Life [ Time Frame: 24 weeks ]
