Trial Outcomes & Findings for PK/PD, Long-term Safety and Efficacy of Tamsulosin Treatment in Children With Neurogenic Bladder (NCT NCT00340704)

Results Overview

Group D-Denovo: Leak point pressure (LPP) Response at(response defined as a subject who achieves an LPP pressure \<40 cm H2O) at the end of treatment based on two confirmatory values. Group D-527.51 Rollover: Leak point pressure (LPP) Response at (response defined as a subject who achieves an LPP pressure \<40 cm H2O) last value of the treatment based on two confirmatory values. The last value on treatment included any final value prior to discontinuation of treatment, regardless of the length of treatment. Detrusor leak point pressure (LPP) recorded in cm H2O which was obtained using a standard urodynamic technique, a cystometrogram. Descriptive statistics were used to assess this endpoint. 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.

Measure	Tamsulosin - Low Dose Level (PK Study) Subjects randomized to low dose level (0.001-0.002 mg/kg) of tamsulosin hydrochloride, dependent on a subject's body weight. In PK study, all subjects were titrated to their randomized dose level that they needed to receive which was based on their weight. Depending on the results of the Leak point pressure (LPP) results, subjects could remain on that dose if it was found to be efficacious or go back to a lower efficacious dose or titrate up in hopes that the higher dose would provide some efficacy. Subjects with body weight of 12.1-25.0 kg received low dose of 0.025 mg qd (once daily), body weight of 25.1-50.0 kg received low dose of 0.05 mg qd and body weight of 50.1-100.0 kg received low dose of 0.1 mg qd by sprinkling the content of the capsule(s) over teaspoon of apple sauce or yogurt taken 30 minutes after breakfast.

Population: Full analysis set (FAS-LPP): This subject set includes all subjects in the Treated set who received one dose of treatment and had one on treatment LPP measurement.

Group D-Denovo: Leak point pressure (LPP) Response at(response defined as a subject who achieves an LPP pressure \<40 cm H2O) at the end of treatment based on two confirmatory values. Group D-527.51 Rollover: Leak point pressure (LPP) Response at (response defined as a subject who achieves an LPP pressure \<40 cm H2O) last value of the treatment based on two confirmatory values. The last value on treatment included any final value prior to discontinuation of treatment, regardless of the length of treatment. Detrusor leak point pressure (LPP) recorded in cm H2O which was obtained using a standard urodynamic technique, a cystometrogram. Descriptive statistics were used to assess this endpoint. 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.

Measure	Tamsulosin - High Dose Level (Group D-527.51 Rollover) Subjects titrated to high dose level (0.004-0.008 mg/kg) of tamsulosin hydrochloride, once daily dependent on a subject's body weight. In Group D-527.51 Rollover, once subjects exited the double-blind trial they were rolled over into this trial. All subjects had to titrate to their efficacious dose. Doses that were available were based on subject's weight. Depending on the LPP results, subjects could remain on that dose if it was found to be efficacious or titrate up in hopes that the higher doses would provide some efficacy.
