Trial Outcomes & Findings for Augmentation Cystoplasty Using an Autologous Neo-Bladder (NCT NCT00419120)

NCT ID: NCT00419120

Last Updated: 2015-11-30

Results Overview

Efficacy of the autologous neo-bladder construct as assessed by a responder analysis (comparing each patient's baseline with 12 month data). Improvement in compliance (i.e. improved bladder pressure/volume relationship) was measured by urodynamics at predetermined bladder pressure points. This was coupled with an assessment of clinical benefit and used to determine responders versus non-responders

Participant Flow

11 patients were recruited between Dec 2006 and July 2007. Patients were recruited from 4 academic centers across the US. One patient withdrew from the study prior to implantation of the Neo-bladder construct and is included in the safety analysis, but not in the efficacy analysis (all implanted population).

This was an open label single arm study.

PRIMARY outcome

Timeframe: 12 months

Population: The analysis population of the primary outcome measure is the all implanted population (Intent to Treat - ITT). There was no imputation of analysis measures.

Efficacy of the autologous neo-bladder construct as assessed by a responder analysis (comparing each patient's baseline with 12 month data). Improvement in compliance (i.e. improved bladder pressure/volume relationship) was measured by urodynamics at predetermined bladder pressure points. This was coupled with an assessment of clinical benefit and used to determine responders versus non-responders

SECONDARY outcome

Timeframe: periodically within first 12 months as well as during long term follow up out to 5 years

clinical evaluation of adverse events, laboratory parameters and urinary imaging to assess any safety issues emerging from this technology and to allow a comparison of a safety profile with standard of care enterocystoplasty. Please refer to the Adverse Event section for detailed information.
