- Primary Safety Endpoints (composite outcome measure) [ Time Frame: 12 months ]
- Rate, frequency and severity of all adverse events including; hypoglycemic episodes; injection reactions; hypersensitivity reactions; evidence of infection and posterior leukoencephalopathy syndrome.
- Vital signs, standard hematology and chemistry tests, physical examinations.
- Immunological Endpoints (composite outcome measure) [ Time Frame: 12 months ]
- Immune phenotyping via flow cytometry of all Interleukin (IL)-12, IL-23, IL-17, Interferon(IFN)-γ secreting immune subsets.
- Basic immune phenotyping of white blood cell subsets.
- Human leukocyte antigen(HLA)- A, B, C, DR, DP, DQ typing.
- Fluorospot (ELISpot) analysis for IL-17 and IFN-γ secretion in response to whole insulin and antigens for Cluster of differentiation (CD)8+ and CD4+ T cells .
- Luminex assessment of serum cytokines IL-17, IFN-γ, IL-12 and IL-23.
- Regulatory T cell : Effector T cell ratio
- CD154 based assays to determine diabetogenic antigen specific responses of T helper cells.
- Epigenetic assessment of Treg phenotype and function.
- Exploratory (composite outcome measure) [ Time Frame: 12 months ]
- Mixed-meal tolerance test (MMTT) - stimulated 2-hour C-peptide area under the curve (AUC) at weeks 4, 28 and 52.
- Insulin use in units per kg body weight per day at weeks 4, 16, 28, 40 and 52.
- HbA1C levels at weeks 4, 16, 28, 40 and 52.
