Outcome Measures

Primary Outcomes (2)

  • Safety assessment: Registration of adverse events

    Changes in safety parameters of patients during the study period since baseline. Measured through the registration of adverse events.

    Throughout the study until Week 52

  • Efficacy Assessment: Evaluation of islet function

    Change of C-peptide Area Under the Curve (AUC) (0-120 min) for Mixed Meal Tolerance Test (MMTT) at Week 52 compared to test performed before start of treatment.

    Throughout the study until Week 52

Secondary Outcomes (2)

  • Efficacy Assessment: HbA1c

    Week 52

  • Dose of exogenous insulin

    Week 52

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Meets the 1999 World Health Organization diagnostic criteria for diabetes.
  • Aged 18-70, no gender restriction.
  • Islet function failure: fasting C-peptide \< 0.1 nmol/L, 2-hour postprandial C-peptide \< 0.2 nmol/L, and HbA1c ≥ 7%.
  • Meets the indications for islet transplantation alone:
  • i. Type 1 diabetes patients who experience unstable blood glucose despite strict insulin therapy, including frequent hypoglycemia or at least one severe hypoglycemic event in the past 12 months, or those with serious complications in other organs such as the kidneys; ii. Type 2 diabetes progressing to islet failure with poor blood glucose control as described above; iii. Patients with chronic pancreatitis or non-malignant pancreatic tumors who have undergone total or near-total pancreatectomy may receive autologous islet transplantation concurrently or allogeneic islet transplantation later.
  • The patient and their family or legal guardian voluntarily consent to stem cell transplantation therapy and sign the informed consent form.

You may not qualify if:

  • Diabetic ketoacidosis that is not yet controlled.
  • Severe allergic constitution, meaning prone to allergic reactions without a clear and identifiable cause.
  • BMI \< 14 or \> 35.
  • Severe anemia (hemoglobin \< 8 g/dL in males, \< 7 g/dL in females).
  • HIV-positive, carriers of viral hepatitis or in the active phase, or other uncontrolled infectious diseases.
  • History of acute pancreatitis, pulmonary embolism, or other thrombotic diseases, as well as severe heart, liver, kidney, respiratory, or neurological diseases.
  • Patients with gestational diabetes, monogenic diabetes, diabetes due to pancreatic damage, or other secondary diabetes (e.g., diabetes caused by Cushing's syndrome, thyroid dysfunction, or acromegaly).
  • Pregnant women or those planning pregnancy within 3 months before or after treatment, and women who are breastfeeding.
  • Patients with mental illness, alcohol or drug abuse, who are unable to cooperate with treatment.
  • Known or suspected tumors.
  • History of other autoimmune diseases or hematological disorders.
  • Any other clinical conditions that, in the investigator's judgment, may pose a risk to the participant's safety.
