Secondary

MeasureTime frameDescription
Percent Change From Baseline in LPP for Group D-527.51 RolloverBaseline and Week 1Percent change from baseline in actual detrusor leak point pressure (LPP) by treatment group (subjects are classified according to the treatment they were taking at end of treatment) and Week. Baseline assessments were obtained from trial 527.51 for Group D-527.51 Rollover. The results from Week 1 were reported because there were very few subjects who reported data at subsequent visits due to the termination of the trial. This Outcome Measure was only pre-specified for Group D-527.51 Rollover subjects, so results of this group is provided.

Group D-527.51 Rollover: Baseline, Week 26 and Week 52.Response defined as stabilization or improvement of hydroureter measured by renal ultrasound compared to baseline by treatment group (subjects are classified according to the treatment they were taking at Week 52 or end of treatment) at week 52 for Group D-Denovo and (subjects are classified according to the treatment they were taking at the end of treatment) at last value on treatment for Group D-527.51 Rollover. Baseline assessments were obtained from trial 527.51 for Group D-527.51 Rollover. The overall treatment duration was not sufficient to reach any meaningful conclusions regarding improvement or stabilization of hydroureter in the Group D-527.51 Rollover. Hydroureter response is defined as improvement or stabilization based upon the presence or absence of hydroureter at end of treatment compared to baseline. This Outcome Measure was only pre-specified for Group D-Denovo and Group D-527.51 Rollover subjects, so results of these two groups are provided.

Group D-527.51 Rollover: Baseline, Week 26 and Week 52.Response defined as stabilization or improvement of hydronephrosis measured by renal ultrasound compared to baseline by treatment group (subjects are classified according to the treatment they were taking at Week 52 or end of treatment) at week 52 for Group D-Denovo and (subjects are classified according to the treatment they were taking at the end of treatment) at last value on treatment for Group D-527.51 Rollover. Baseline assessments were obtained from trial 527.51 for Group D-527.51 Rollover. The overall treatment duration was not sufficient to reach any meaningful conclusions regarding improvement or stabilization of hydronephrosis in the Group D-527.51 Rollover. Hydronephrosis response is defined as an improvement or stabilization based upon ultrasound grading at the end of the study. The lower or same grade at end of treatment compared to baseline is considered an improvement or stabilization.

Number of LPP Responders at Each Visit Over Time (Classified by Last Value on Treatment) for Group D-527.51 Rollover.

Number of Leak point pressure (LPP) Responders at each visit (week) over time (classified by last value on treatment). Due to the early termination of the study, most of the LPP assessments were conducted within Weeks 1-9 of treatment. Summary of LPP response rates provided over time.The subjects are classified according to the treatment they were receiving at the last value on treatment. Therefore, no assumptions can be made regarding what dose they were receiving at a particular time point. LD: Low Dose, MD: Medium Dose and HD: High Dose This Outcome Measure was only pre-specified for Group D-527.51 Rollover subjects, so results of this group is provided.

Time frame: Week 1 (Visit 3) , Week 2 (Visit 4) , Week 3 (Visit 5) and Week 4 (Visit 6) prior to dose administration and Week 9 (Visit 7) (optional), Week 13 (Visit 8) (additional), Week 26 (Visit 9) (optional) and Week 52 (Visit 11) after drug administration.

RA,Cmax

The accumulation ratio was calculated from the patients who were randomised to the low dose group and for whom both parameters at first dose and steady state dose were available. Accumulation ratios of tamsulosin HCl in plasma at steady state after multiple dose administration over a uniform dosing interval τ, expressed as ratio of Cmax at steady state and after single dose. The accumulation ratio RA,Cmax was calculated as: Cmax,ss/Cmax,1. This Outcome Measure was only pre-specified for PK Study- steady state group subjects, so results from this group is provided.

Response Defined as Stabilization or Improvement of Hydronephrosis Measured by Renal Ultrasound Compared to Baseline for Group D-Denovo and Group D-527.51 Rollover

Response defined as stabilization or improvement of hydronephrosis measured by renal ultrasound compared to baseline by treatment group (subjects are classified according to the treatment they were taking at Week 52 or end of treatment) at week 52 for Group D-Denovo and (subjects are classified according to the treatment they were taking at the end of treatment) at last value on treatment for Group D-527.51 Rollover. Baseline assessments were obtained from trial 527.51 for Group D-527.51 Rollover. The overall treatment duration was not sufficient to reach any meaningful conclusions regarding improvement or stabilization of hydronephrosis in the Group D-527.51 Rollover. Hydronephrosis response is defined as an improvement or stabilization based upon ultrasound grading at the end of the study. The lower or same grade at end of treatment compared to baseline is considered an improvement or stabilization.

Time frame: Group D-Denovo: Baseline and Week 52. Group D-527.51 Rollover: Baseline, Week 26 and Week 52.

This Outcome Measure was only pre-specified for PK Study- steady state group subjects, so results of this group is provided.

Time frame: -0.25h prior to dose and 2h, 4h, 6h, 8h, 10h, 24h and 33h after the drug administration.

Population: Pharmacokinetics steady state set (PK-SS)
