History of Changes

Purpose

This study is a phase 2, single-center, prospective, randomized, double-blind, placebo-controlled, 3-arm parallel group (1:1:1) intervention trial to determine the efficacy of 4 weeks rapamycin treatment and 4 weeks rapamycin treatment plus 3 months vildagliptin treatment versus placebo in increasing endogenous insulin production and correcting glycemic lability. It will involve 60 patients with long standing type 1 diabetes (T1D). Patients will receive for one month placebo (Group 1), rapamycin plus placebo (Group 2), or rapamycin plus Vildagliptin (Group 3). Rapamycin will be administered at an initial dose 0.2 mg/kg orally on day 0 followed by 0.1 mg/kg/die (target trough levels: 8-10 ng/ml). Vildagliptin will be administered at a dose of 50 mg x2/die starting from day 0. After 4 weeks of treatment (period A), patients will discontinue rapamycin or relevant placebo treatment, but continue Vildagliptin or placebo for a further 8 weeks and be monitored over this period (period B).

Arms	Assigned Interventions
Placebo Comparator: Group 1: Placebo Eligible participants will be randomized to one of three treatment arms. In this arm patients will received placebo x 2 placebo (Group 1) After 4 weeks of treatment, patients will discontinue relevant placebo treatment, but continue the second placebo for a further 8 weeks	Drug: Placebo 1 Placebo 1 will be titrated according to a random schedule alternating plausible doses of placebo. After 4 weeks of treatment patients will discontinue placebo 1 Drug: Placebo 2 Placebo 2 will be administered BID starting from day 0. After 8 weeks of treatment patients will discontinue placebo 2
Experimental: Group 2: Rapamycin plus Placebo Eligible participants will be randomized to one of three treatment arms. In this arm patients will received rapamycin plus placebo. After 4 weeks of treatment, patients will discontinue rapamycin, but continue the second placebo for a further 8 weeks	Drug: rapamycin Rapamycin will be administered at an initial dose 0.2 mg/kg on day 0, followed by 0.1 mg/kg/die. The daily dose will be adjusted to the whole blood 24-hr trough to target, as tolerated, 8-10 ng/mL Other Name: Rapamune® Drug: Vildagliptin Vildagliptin will be administered at a dose of 50 mg x2/die starting from day 0. Other Name: GALVUS
Experimental: Group 3: Rapamycin plus Vildagliptin Eligible participants will be randomized to one of three treatment arms. In this arm patients will received rapamycin plus vildagliptin. After 4 weeks of treatment, patients will discontinue rapamycin , but continue Vildagliptin o for a further 8 weeks	Drug: rapamycin Rapamycin will be administered at an initial dose 0.2 mg/kg on day 0, followed by 0.1 mg/kg/die. The daily dose will be adjusted to the whole blood 24-hr trough to target, as tolerated, 8-10 ng/mL Other Name: Rapamune® Drug: Vildagliptin Vildagliptin will be administered at a dose of 50 mg x2/die starting from day 0. Other Name: GALVUS
