ClinConnect Summary

In contrast to currently approved therapies that are directed at controlling either the metabolic abnormalities or tissue complications of diabetes, INGAP Peptide therapy is intended to restore ß cell mass and islet cell function. INGAP Peptide has been identified as a substance that induces islet cell regeneration from progenitor cells resident in the pancreas in a manner that recapitulates islet development during normal embryogenesis.

INGAP Peptide therapy has been evaluated in phase 1 and 2 studies of both T1DM and T2DM patients (Dungan K, Diab Met Res Rev 2009; 25:558-565). Once daily...
