Outcome Measures
Primary Outcome Measures
- C-peptide change [12 months post-transplant]
Evaluation of the magnitude of C-peptide change after transplantation
Secondary Outcome Measures
- the proportion of subjects with HbA1c ≤7.0% and no severe hypoglycemic events [52 weeks post-transplant]
- The proportion of subjects who are insulin-independent [12 weeks and 52 weeks post-transplant]
- The percentage reduction in insulin requirement [12 weeks and 52 weeks post-transplant]
- Glycemic control (MAGE) [12 weeks and 52 weeks post-transplant]
Evaluation of the average amplitude of glycemic fluctuations (MAGE) in subjects
- Evaluation of the severity of hypoglycemia using the Ryan Hypoglycemia Severity Score (HYPO) [baseline and 52 weeks post-transplant]
- Quality of life score [baseline and 52 weeks post-transplant]
Evaluation of the quality of life score in subjects

-
Known hemoglobin-related diseases, anemia (moderate to severe), or other known hemoglobinopathies that interfere with HbA1c measurement (such as sickle cell disease).
-

-
Previous history of coagulation disorders or requiring long-term anticoagulant therapy (e.g., warfarin) (low-dose aspirin therapy is allowed) or patients with INR >1.5.
-

-
Received live virus vaccines within the past 6 months or planned to receive live virus vaccines during the trial or within 1 month after treatment. Live vaccines include, but are not limited to, measles, mumps, rubella, varicella, yellow fever, rabies, Bacillus Calmette-Guérin, typhoid vaccine, COVID-19 vaccine, etc.
-
Previous history of pancreatic cancer, intraductal papillary mucinous neoplasm of the pancreas, end-stage lung disease, or liver cirrhosis.
-
Other abnormal laboratory test results deemed clinically significant by the investigator.
-
Patients with severe mental illness.
-
Participated in a drug or medical device clinical trial within the past 3 months and received investigational drugs or medical devices; or within 5 half-lives of another drug before screening (if the half-life exceeds 3 months).
-
Currently receiving long-term (continuous for ≥14 days) systemic pharmacological doses of glucocorticoids or other medications that may affect the participant's consciousness.
-
Treatment (local, intra-articular, intraocular, or inhalation preparations) for any other factors or diseases not mentioned above, deemed unsuitable for participation in this clinical study by the investigator.
