Overview

This trial is active, not recruiting.

Condition acute lymphoblastic leukemia
Treatments haplo-identical hsct, chemotherapy
Phase phase 3
Sponsor Peking University
Start date January 2014
End date December 2017
Trial size 300 participants
Trial identifier NCT02042690, ALL-13

Summary

The survival of adult patients with standard-risk acute lymphoblastic leukemia(ALL) need to improve. We want to compare the efficacy of haplo-identical hematopoietic stem cell transplantation (HSCT) with chemotherapy for adult(age:18-39 years old) ALL patients in first phase of complete remission (CR1)

Patients receive 6 cycles of consolidation chemotherapy after randomization, including Hyper-CVAD-B regimen-Hyper-CVAD-A regimen/Hyper-CVAD-B regimen/Hyper-CVAD-A regimen/Hyper-CVAD-B regimen/Hyper-CVAD-A regimen.Maintenance treatment includes MTX 20mg/m2/w,po,6-mercaptopurine 60 mg/m2/d,po,d1-d28,VP(VDS 4mg,d1, Prednisone 1mg/kg d1-7) every one month for 2 years.
(Experimental)
Haplo-identical HSCT Protocol:G, donor treatment with recombinant granulocyte colony-stimulating factor (rhG-CSF); I, intensified immunologic suppression; A, antihuman thymocyte immunoglobulin (ATG) for the prevention of GVHD; C, combination of peripheral blood stem cell transplantation (PBSCT), and bone marrow transplantation (BMT),named GIAC regimen. Graft versus-host disease(GVHD) prevention regimen: CSA/MMF/MTX, cyclosporine A(CSA) 1.25mg/kg/d, i.v administrated in two doses from day -109 until bowel function returned to normal, at which time patients receive oral CSA until 12months after HSCt and then gradually tapered. Every 12h, 0.5g mycophenolate mofetil (MMF)(0.25g for children) was administrated orally from day -10 to +30 and subsequently 0.25g from days +30 to +60. Methotrexate (MTX) was administrated at a dose of 15mg/m2 on day +1 and 10mg/m2 on days +3,+6, and +11.

Haplo-identical Protocol: GIAC regimen. GVHD prevention regimen: CSA/MMF/MTX, CSA 1.25mg/kg/d, i.v administrated in two doses from day -109 until bowel function returned to normal, at which time patients receive oral CSA until 12months after HRD-HSC and then gradually tapered. Every 12h, 0.5g MMF(0.25g for children) was administrated orally from day -10 to +30 and subsequently 0.25g from days +30 to +60.

Additional Information

Official title A Randomised Phase III Study to Compare Haplo-identical HSCT Versus Chemotherapy in First Remission for Standard-risk Adult Acute Lymphoblastic Leukemia
Principal investigator Xiao-Jun Huang, MD
Description Although the high complete remission rate (80%-90%) can be achieved, the long-term survival rate of standard-risk adult patients with acute lymphoblastic leukemia(ALL) is only 25%-55% when they receive chemotherapy alone. The survival rate can be further improved uo to 50%-75% when they receive HLA-matched HSCT However, the chance of finding a HLA-matched donor is low, especially in China. Alternative donor such as halpo-identical related donor might be an choice. Our retrospective analysis showed about 59% overall survival could be achieved when standard-risk adult ALL patients received halpo-identical HSCT.Therefore, we start this randomization controlled trial to compare the efficacy of haplo-identical HSCT with chemotherapy for adult(age:18-39 years old) ALL patients in CR1.
