Further study details as provided by University of Miami:

Primary Outcome Measures:
  • determine the rate of allosensitization in patients after failed islet transplantation [ Time Frame: 10 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 60
Study Start Date: December 2008
Estimated Study Completion Date: July 2021
Estimated Primary Completion Date: December 2020 (Final data collection date for primary outcome measure)
Detailed Description:
After complete islet graft loss is determined, patient's maintenance immunosuppression (i.e. sirolimus, tacrolimus, MMF and/or Myfortic®) will be discontinued and they will be monitored for 10 years thereafter, for the appearance of allosensitization using panel reactive antibody (PRA) levels and monitor the persistence of elevated PRA levels. Primary objective is to determine the rate of allosensitization in patients 3 years after failed islet transplantation (i.e. stimulated c-peptide <0.3mg/mL) and monitor the persistence of elevated PRA levels (≥ 20%) at year 3, 6, and 9. Timing, frequency and level of change in PRA will be monitored after all immunosuppression is discontinued.
