Outcome Measures

Primary Outcomes (1)

  • Adverse effects

    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.

    2 years

Secondary Outcomes (8)

  • Change in HbA1C

    2 years

  • Change in C-peptide

    2 years

  • Change in insulin dose

    2 years

  • Hypoglycaemic events

    2 years

  • Change in titer of autoantibodies

    2 years

  • +3 more secondary outcomes

Study Arms (4)

UCB-Treg plus Liraglutide

EXPERIMENTAL

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.
