Allogeneic Transplantation for Pediatric Leukemias With Unrelated Donors

NCT ID: NCT00679536

Last Updated: 2014-01-23

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 30 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2008-05-31
• Study Completion Date: 2015-05-31

Brief Summary

The study proposes the use of Fludarabine, Busulfan, Anti Thymocyte Globulin Rabbit (ATG) and Total Body Irradiation as a preparative regimen before hematopoietic stem cell transplant from unrelated donor peripheral blood stem cells (PBSC). The hypothesis states that the 100 day mortality after this type of transplant will be significantly below the accepted standards, which is about 30% for unrelated donors.

Detailed Description

The primary objective of this study is to evaluate the toxicity (as measured as 100 day survival) after hematopoietic stem cell transplant from an unrelated donor with a novel preparative regimen of Fludarabine, Busulfan, Anti-Thymocyte Globulin, and Total Body Irradiation for pediatric patients with leukemia. The secondary objectives are to evaluate the relapse-free and overall survival after hematopoietic stem cell transplant as well as to evaluate the incidence of acute and chronic graft-versus-host disease after this preparative regimen.

Study Groups

A

All patients on this trial will receive a conditioning regimen of Busulfan, Fludarabine, Anti-Thymocyte Globulin and Total Body Irradiation (400 cGy)

Group Type: EXPERIMENTAL

Busulfan

Intervention Type: DRUG

Patient will receive a Test Dose of Busulfan on either Day -10 or Day -9. Patient will receive their Regimen Dose of Busulfan on Day -5 to Day -2. The regimen dose of Busulfan will be based off of the findings from their Test Dose.

Fludarabine

Intervention Type: DRUG

Patient will receive Fludarabine from Day -6 to Day -2. The dose of Fludarabine will be 30 mg/m\^2/day.

Thymoglobulin

Intervention Type: DRUG

The patient will also receive Thymoglobulin (rabbitATG) on Day -4 to Day -2. Each dose of rabbitATG will be 1.5 mg/kg/day.

Total Body Irradiation

Intervention Type: RADIATION

On Day -1 the patient will receive a total of 400 cGy of Total Body Irradiation.

• High risk first remission, defined as:

• Ph+ ALL; or,
• MLL rearrangement with slow early response [defined as having M2 (5-25% blasts) or M3 (>25% blasts on bone marrow examination on Day 14 of induction therapy)]; or,

• Bone marrow relapse < 36 months from induction; or >36 mths if a matched sibling donor is available
• T-lineage relapse at any time; or,
• Very early isolated CNS relapse (<18 months from diagnosis); or,
• Slow reinduction (M2-3 at Day 28) after relapse at any time.
• Any third or subsequent CR.
• Biphenotypic or undifferentiated leukemia in any CR or if in first relapse must have < 25% blasts in bone marrow
