---|---|
Experimental: UCB-Treg plus Liraglutide
Subjects will receive a single infusion of ex vivo expanded umbilical cord blood derived Treg product (2 x 10^6). Dose escalation of liraglutide up to 1.2 mg will be started 3 days after Treg infusion only if no severe side effects showed. Subjects continue to receive the reached liraglutide dose once daily for 6 months thereafter. Insulin will be continued as a routine therapy.
|
Drug: Liraglutide
Dose escalation of Liraglutide starts from 0.6 mg up to 1.2 mg per day. Biological: UCB-Treg Receive Treg infusion: 1~5*10^6/kg b.w. in 100ml normal saline Drug: Insulin Receive insulin following clinician's instruction. |

- Adverse effects [ Time Frame: 2 years ]Primary outcome measures will be the number of participants with adverse events, laboratory abnormalities and other signs of toxicity. Particular focus will be on the number and severity of infusion reactions, complications related to infection, and any potential negative impact on the course of diabetes.
- Change in HbA1C [ Time Frame: 2 years ]Measure the HbA1C level after treatment
- Change in C-peptide [ Time Frame: 2 years ]Measure the C-peptide level after treatment
- Change in insulin dose [ Time Frame: 2 years ]Measure insulin dose patient used after treatment
- Hypoglycaemic events [ Time Frame: 2 years ]Measure the number of participants with Hypoglycaemic events
- Change in titer of autoantibodies [ Time Frame: 2 years ]Measure the titer of antoantibodies of participant after treatment
- Change in immune cells diversities and quantities. [ Time Frame: 2 years ]Measure the immune cells diversities and quantities after treatment
- Change in autoimmune-related cytokines [ Time Frame: 2 years ]Measure the change of autoimmune- related cytokines after treatment
- Life quality evaluation [ Time Frame: 2 years ]Number of participants with disturbance of emotion, sleep, resting or energy.
