研究目的:

评价具有免疫分型的胰腺类器官用于治疗T3c型糖尿病患者的临床安全性和有效性。  

Objectives of Study:

To evaluate the clinical safety and efficacy of immunotyped pancreatic endocrine organoids for the treatment of patients with type 3c diabetes mellitus (T3cDM).

药物成份或治疗方案详述:

从患者手术切除的局部胰腺组织中分离出胰岛细胞,体外扩增培养后进行HLA分型、类器官功能检测并建库。在HLA配型后,经皮肝穿刺输入T3c 糖尿病患者,观察52 周的细胞治疗安全性和与血糖管控相关的临床有效性评估。 

Description for medicine or protocol of treatment in detail:

Islet cells are isolated from resected pancreatic tissue obtained from patients undergoing surgery, followed by ex vivo expansion and culture. Subsequent procedures include HLA typing, functional assessment of organoid-like structures, and biobanking. After matching for HLA, the cells are administered into patients with type 3c diabetes mellitus (T3cDM) via ultrasound-guided percutaneous transhepatic portal vein catheterization. A 52-week follow-up is conducted to evaluate the safety of the cell therapy and its clinical efficacy in glycemic control.

Participants with HBcAb positivity and HBV DNA <2000 IU/mL (<10⁴ copies/mL) must undergo regular HBV DNA monitoring throughout the study; Positive for hepatitis C virus (HCV) antibody with peripheral blood HCV RNA >=10³ IU/mL; Positive for human immunodeficiency virus (HIV) antibody; Active syphilis infection (participants with adequately treated syphilis may be eligible); Positive cytomegalovirus (CMV) DNA; Positive nucleic acid test for COVID-19;** 6.
