Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 years to 45 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

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

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To assess participant safety & feasibility of study drug administration
Time Frame: Study duration is 2 years
Study duration is 2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
To assess AAT treatment on the maintenance of c-peptide production
Time Frame: Stimulated c-peptide at year one and two.
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.
Continuous Glucose Monitoring at one and two years.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
