Tengion Identifier:
First received: March 15, 2010
Last updated: December 9, 2014
Last verified: December 2014
The purpose of this study is to see if the Neo-Urinary Conduit(NUC), which is made in the laboratory from a combination of a patient's own cells and other materials can be used to form a conduit to safety allow urine flow from the kidneys to outside the body after radical cystectomy in patients with bladder cancer.

Condition Intervention Phase
Bladder Cancer
Device: Neo-Urinary Conduit
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Phase 1 Open Label Exploratory Study of an Autologous Neo-Urinary Conduit in Subjects Requiring Incontinent Urinary Diversion Following Radical Cystectomy

Further study details as provided by Tengion:

Primary Outcome Measures:
  • Structural integrity and conduit patency [ Time Frame: 12 months post implantation ]
    CT scan will be used to demonstrate that urine is able to flow safety through the NUC

Secondary Outcome Measures:
  • Structural integrity and conduit patency [ Time Frame: month 12 through month 60 post implantation ]
    CT scan and renal ultrasound will be used to demonstrate that urine is able to flow safely through the NUC through 60 months post implantation

  • Procedure and/or product related AEs [ Time Frame: month 12 through month 60 post implant ]
    procedure and/or product related AEs will be evaluated through month 60 post implantation

  • Overall safety [ Time Frame: from enrollment through month 60 post implant ]
    overall safety will be assess by evaluation of non-product/procedure related adverse events, vital signs and laboratory parameters

  • Procedure and/or product related adverse events post implantation [ Time Frame: through 12 months post implantation ]
    Evaluation of procedure and/or product related adverse events

Enrollment: 8
Study Start Date: March 2010
Study Completion Date: December 2014
Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Implanted with NUC
Patients who have been implanted with the Neo-Urinary Conduit
Device: Neo-Urinary Conduit
Implantation with the autologous Neo-Urinary Conduit
Other Name: NUC

Detailed Description:
The NUC under investigation is a regenerative medicine product comprised of the patient's own smooth muscle cells, procured from a fat biopsy. Tengion has developed appropriate culture conditions to reproducibly generate the necessary quantities of SMC in vitro from autologous adipose tissue biopsies. The NUC is produced at Tengion's Good Manufacturing Practices (GMP) qualified clinical production facility. In this process, smooth muscle cells (SMC) obtained from an adipose tissue biopsy are propagated ex-vivo for approximately 3 - 4 weeks. At the end of this process, the SMCs are seeded onto the surface of a biodegradable PGA/PLGA mesh scaffold to form the NUC. The NUC is shipped to the investigative site for surgical implantation. Over time, the NUC should facilitate the regeneration of urinary tract tissue.
