Primary Outcome Measures:
  • To assess participant safety & feasibility of study drug administration [ Time Frame: Study duration is 2 years ]

Secondary Outcome Measures:
  • To assess AAT treatment on the maintenance of c-peptide production [ Time Frame: Stimulated c-peptide at year one and two. ]
  • Assess the effects of AAT on glycemic variability and A1c. [ Time Frame: Continuous Glucose Monitoring at one and two years. ]

Eligible subjects will be treated once a week for 8 weeks (8 total treatments).
Other Names:
  • Alpha-1 Antitrypsin
  • AAT
  • Aralast NP


Ages Eligible for Study:   6 Years to 45 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of Type 1 Diabetes Mellitus based on ADA Criteria for fewer than 5 years but more than 100 days
  • 6-45 years of age, inclusive. To assess safety, we will initially enroll 8 patients over the age of 16. Following the last infusion of the 8th patient, we will assess adverse events. As long as there are no stopping criteria met for these 8 patients we will decrease the age criteria down to 6 years old.
  • C-peptide increase during screening mixed meal tolerance test with a minimal stimulated value of ≥ 0.2 pmol/mL.
  • Positive for antibodies to insulin (if insulin autoantibody positive only, determination must be within two weeks of insulin initiation), GAD-65, IA-2 or ZnT8
  • Agree to intensive management of diabetes with an HgbA1c goal of < 7.0%
  • If female, (a) surgically sterile or (b) postmenopausal or (c) if of reproductive potential, willing to use medically acceptable birth control (e.g. female hormonal contraception, barrier methods or sterilization. ) until 3 months after completion of any treatment period
  • If male and of reproductive potential, willing to use medically acceptable birth control until 3 months after completion of any treatment period, unless the female partner is postmenopausal or surgically sterile
  • Serum creatinine ≤ 1.5 x upper limit of normal
  • AST < 2 times the upper limit of normal
  • Hematology:WBC > 3000 x 109/L; platelets > 100 x 109/L; hemoglobin > 10.0 g/dL.

Exclusion Criteria:

  • Unable or unwilling to comply with the requirements of the study protocol
  • Body Mass Index (BMI) > 30 kg/m2
  • Unstable blood sugar control defined as one or more episodes of severe hypoglycemia (defined as hypoglycemia that required the assistance of another person) within the last 30 days
  • Previous immunotherapy for T1D
  • Administration of an experimental agent for T1D at any time or use of an experimental device for T1D within 30 days of screening, unless approved by the study PI
  • History of any organ transplant, including islet cell transplant
  • Active autoimmune or immune deficiency disorder (e.g. sarcoidosis, rheumatoid arthritis)
  • Serum bilirubin > ULN, except those subjects whose abnormal values were attributed to any stable, benign condition (such as Gilbert's Syndrome) may be included
  • TSH outside the normal range at screening, except those subjects on stable doses of thyroid hormone replacement therapy may be included
  • Known HIV positivity, active hepatitis B or active hepatitis C infection
  • Anticipated pregnancy during active dosing or within 3 months after completion of active dosing phase
  • History of a malignant neoplasm within the previous 5 years (except in situ cervical cancer and curable non-melanoma skin malignancy)
  • Any social condition or medical condition that would, in the opinion of the investigator, prevent complete participation in the study or that would pose a significant hazard to the subjects' participation
  • History of active substance abuse within 12 months of screening
  • A psychiatric or medical disorder that would prevent giving informed consent
  • Individuals with a history of IgA deficiency
  • Individuals with a history of hypersensitivity to AAT
