Ex Vivo Immunotherapy for Hyperglycemia in Type 2 Diabetes Mellitus (DISC)
2016年1月12日 更新者：Demao Yang、B & Y Technologies
Pilot Study of a Cell-Based Therapy for Treatment of Hyperglycemia in Type 2 Diabetes Mellitus
Diabetes mellitus type 2 is a long-term metabolic disorder that is primarily characterized by insulin resistance, relative insulin deficiency and hyperglycemia.
Our hypotheses is that liver would be the primary organ responsible for the metabolic disorder because of some unknown defects, where sugar would not be efficiently converted to glycogen and fat, leading to hyperglycemia.
The constant hyperglycemia would keep pressure on beta-cells in the pancreas to eventually exhaust their ability to produce and secret sufficient amount of insulin, exacerbating the disease.
The Immunotherapy would enhance the liver functions and correct the abnormal sugar metabolism.
In addition, the ex vivo activated cells produce and secret growth factors which would help endothelial cells of blood vessels to reproduce and grow, resulting in reduced arteriosclerosis.
研究概览
详细说明
We plan to recruit 20 patients with type 2 diabetes mellitus who suffer hyperglycemia with or without medication.
The patients will come to our hospitals for the treatment.
A small amount of peripheral blood will be drawn and processed and cultured in our laboratory.
The cultured cells (autologous) will be infused intravenously back to patients.
Levels of plasma hemoglobin A1c (HbA1c) and other metabolic parameters before and after the therapy will be compared.
The therapy is planned to take four weeks for each patient.

干预/治疗 |
|---|---|
|
实验性的：ex vivo activated immune cells
Up to 20 patients diagnosed with type 2 diabetes mellitus and hyperglycemia will be enrolled and assigned to a single treatment group.
Patients will give a small amount of peripheral blood and the blood will be processed and cultured in our laboratory.
The ex vivo activated autologous blood cells will be infused intravenously back to patients.
The treatment will be done twice a week for consecutive 4 weeks.
The metabolic parameters of patients before and after the therapy will be compared to determine if the therapy is safe and effective.
|
The patients who take medication before the enrollment will be required to reduce at least half the amount of the medication before the treatment.
The reduction of the medication will continue during and after the therapy until the levels of plasma hemoglobin A1c (HbA1c) increase to equal or above the levels of the baseline measured before the treatment.
