eDC-MDS: Hypomemylating Agents Combination With eDC Therapy for Elderly Patients With Myelodysplastic Syndrome
Study Details
Study Description
Brief Summary
The purpose of this study is to optimize the traditional treatment scheme and explore the cure scheme for the elderly by combining the existing mature treatment technology. The primary aim of this innovative immunotherapy using WT1/hTERT/Survivin-loaded DCs is to determine whether this novel DC vaccination is safe and can significantly prevent clinical relapse and increase survival of MDS patients.

Phase 1 |
Detailed Description
Objective Myelodysplastic syndrome (Myelodysplasticsyndromes,MDS) is a highly age-related malignant clonal disease of the hematological system, which is characterized by pancytopenia and transformation to leukemia. In China, the median age of onset of MDS is 70 years old, and the incidence increases with age. It is the most common malignant tumor in the elderly, which seriously threatens the health and survival of the elderly. The 3-year survival rate of traditional combination chemotherapy or demethylation therapy is less than 20%.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Active Comparator: Hypomemylating agent monotherapy Azacitidine 100mg/ times. d × for 10 days (28 days for one cycle) or Decitabine 25mg/ times. d × 5 days ( 28 days is one cycle) |
Biological: DC vaccine
EDC cell therapy collection and administration process. Collection of PBMC for preparation of DC cells for patients with autologous DC cells, patient PBMC was collected 10-16 weeks before administration for the preparation and large-scale culture of DC cells. For the patients with matched DC cells, a small amount of peripheral blood was taken for HLA typing 4 weeks before administration, and then the matched DC cells were cultured on a large scale.
