Subjects with neurogenic bladder secondary to spina bifida (myelodysplasia) that is refractory to medical treatment and require augmentation cystoplasty will be enrolled. The hypothesis is that augmentation cystoplasty using an autologous neo-bladder construct will significantly increase bladder compliance.

Condition Intervention Phase
Neurogenic Bladder
Other: Autologous neo bladder construct
Phase 2

Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label

Further study details as provided by Tengion:

Primary Outcome Measures:
  • Number of Responders as Assessed by Compliance [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    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 Measures:
  • Overall Safety Profile - Number of Participants Experiencing an Adverse Event [ Time Frame: periodically within first 12 months as well as during long term follow up out to 5 years ] [ Designated as safety issue: Yes ]
    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.
