Primary Outcome Measures:
  • Stage A Safety: Side effects reported for entire cohort [ Time Frame: Reported during the first 20-27 days following sP administration ]
    To determine if there are unexpected adverse events with intra arterial delivery of sP into the celiac artery in individuals with Type 1 Diabetes, and evidence of residual beta cell function as reflected by a peak C--‐peptide levels of > 200 pmol/L. Multiple measurements per patient will be aggregated to arrive at one reported value: Number of participants with abnormal laboratory values, adverse events and/or peak C-peptide levels >200pmol/L that are related to treatment.

Secondary Outcome Measures:
  • C-Peptide Levels (small cohort) [ Time Frame: Day 20-27 post sP injection ]
    To determine in an initial small cohort (n=12, toxicity and dose finding cohort) if one or more sP doses significantly increases the basal or stimulated c--‐Peptide levels at Day 20--‐27 post--‐injection using data from Mixed Meal Tolerance Test (MMTT).

  • C-Peptide Levels (large cohort) [ Time Frame: Day 20-27 post sP injection ]
    To assess in a larger cohort (n=40, continued safety and efficacy) whether sP dose, determined from the dose finding cohort, significantly increases basal or stimulated C-- peptide levels at Day 20--‐27 post sP--‐injection using MMTT data.

Other Outcome Measures:
  • sP Longevity [ Time Frame: 3 and 6 months ]
    To determine an estimate of sP longevity in the entire cohort of patients, by monitoring HbA1c values, exogenous insulin requirement, daily recorded blood sugar levels and adverse event recording at 3 and 6 months post injection of sP. Multiple measurements per patient will be aggregated to arrive at one reported value for the aforementioned outcome measures.
