Long-Term Treatment Effect of DiaPep277 in Type 1 Diabetes

This study has been completed.
Information provided by (Responsible Party):
Andromeda Biotech Ltd. Identifier:
First received: March 20, 2008
Last updated: July 10, 2013
Last verified: July 2013
The study is an open-label extension study, offering patients who participated and completed previous study 901 to continue treatment with DiaPep277 and clinical follow-up, for 2 additional years. The expectation is first to demonstrate that extended treatment with DiaPep277 is safe and second to evaluate the long-term effectiveness of treatment. Only patients who completed the previous 2-year study and still have beta-cell function above a threshold level will be eligible for this extension study.

Primary Outcome Measures:
  • Preservation of endogenous insulin secretion/beta-cell function, as measured by mixed-meal tolerance test stimulated C-peptide secretion. [ Time Frame: every 6 months up to 24 months from T0 ]

Secondary Outcome Measures:
  • improved metabolic control and the insulin dose required to maintain it. [ Time Frame: every 3 months up to 24 months from T0 ]
