Diabetes Mellitus, Type 1 | Drug: IL-2 Drug: Rapamycin | Phase 1 |
At the time of diagnosis with type 1 diabetes, 15-40% of beta cells may remain active and healthy in the pancreas, capable of producing insulin the body needs to regulate blood glucose levels. Because even small amounts of natural insulin production can decrease the long term effects of diabetes, it is essential that these cells are preserved.
This trial will test whether a combination of the drugs Proleukin (IL-2) and Rapamune (sirolimus) may be safely administered to recently diagnosed type 1 diabetes patients and whether it causes changes to the immune system that can halt the autoimmune destruction of the remaining beta cells. This drug combination has been found to be effective for long-term diabetes prevention in mouse models of type 1 diabetes.
This study is a phase I study for individuals 18-45 years of age who have been diagnosed with type 1 diabetes in the past 3-48 months. All participants will be treated with Proleukin (administered subcutaneously 3x per week) for 28 days and Rapamune (taken orally, daily) for 12 weeks. The study will last for 12 months, with additional follow-up of 24 months. The majority of study visits occur within the first 6 months. Mixed meal tolerance tests, in which participants take a milkshake-like drink and have blood sampled over a 2 or 4-hour period, will take place during an initial screening visit and three additional times during the first year. All participants will also receive intensive diabetes management designed to maintain stable blood glucose levels.

Experimental: Rapamycin/IL-2 combination therapy
IL-2 (Proleukin) was administered at 4.5 3 106 IU s.c., three times per week for 4 weeks for a total of 12 doses. Rapamycin (Rapamune or Sirolimus) was administered without a loading dose at 2 mg/day, with adjustments to maintain trough blood levels of 5-10 ng/mL for 3 months.

Drug: IL-2
Administered by subcutaneous injection at a dose of 4.5x10^6 IU/day, three times weekly for 28 days starting on day 0.
Other Name: Proleukin Drug: Rapamycin Administered orally, initial daily dose of 2mg. At day 7, dose adjusted to achieve and maintain whole blood trough levels of 5-10 ng/ml.
