Donor Stem Cell Transplant After Chemotherapy for the Treatment of Recurrent or Refractory High-Risk Solid Tumors in Pediatric and Adolescent-Young Adults
Study Details
Study Description
Brief Summary
This phase II trial investigates side effects and how well donor stem cell transplant after chemotherapy works in treating pediatric and adolescent-young adults with high-risk solid tumor that has come back (recurrent) or does not respond to treatment (refractory). Chemotherapy drugs, such as fludarabine, thiotepa, etoposide, melphalan, and rabbit anti-thymocyte globulin work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before a donor stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. When the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets and may help destroy any remaining cancer cells.

Detailed Description
PRIMARY OBJECTIVE:
- To assess tolerability of allogeneic hematopoietic stem cell transplantation (HCT) for patients with chemo-responsive recurrent/refractory solid tumors as defined by transplant-related mortality (TRM) at day 30 and the rate of grade III or higher organ toxicity (Bearman Regimen-Related Toxicities Scale) attributable to conditioning occurring within 30 days.
SECONDARY OBJECTIVES:
- Assess median time to platelet and neutrophil engraftment. II. Assess incidence of acute graft-versus-host disease (aGVHD) by day 100. III. Assess incidence of chronic GVHD (cGVHD) at day 100 and one year. IV. Assess rate of grade II organ toxicity through day 100. V. Assess rate of graft failure (primary and secondary) through day 100. VI. Assess rate of infectious complications through day 100. VII. Assess progression free survival (PFS) at day 100,180 and 365. VIII. Assess cumulative incidence of relapse, overall survival (OS) at 100 days and 1 year.
OUTLINE:
CONDITIONING REGIMEN: Patients receive thiotepa intravenously (IV) over 2-4 hours and etoposide IV over 60 minutes on days -8 to -6, melphalan IV over 20 minutes on days -5 and -4, and fludarabine phosphate IV over 1 hour on days -5 to -3 in the absence of disease progression or unacceptable toxicity. Patients receiving umbilical cord transplant also receive rabbit anti-thymocyte globulin IV on days -4 and -3.
TRANSPLANT: Patients undergo HSCT on day 0.
GVHD PROPHYLAXIS: Beginning day -2, patients receive tacrolimus or cyclosporine IV continuously until able to receive orally (PO). Patients continue tacrolimus or cyclosporine PO to day 60 and tapered to day 100. Patients also receive mycophenolate mofetil PO or IV every 8 hours until day 40 and tapered to day 90.
After completion of HSCT, patients are followed up for up to 1 year.

Outcome Measures
Primary Outcome Measures
- Transplant-related mortality (TRM) [At 30 days]
The proportion of patients with 30-day TRM will be reported together with the corresponding 95% Bayesian credible interval.
- Rate of grade III or higher organ toxicity attributable to conditioning [Up to 30 days]
Assessed using the Bearman Regimen-Related Toxicities Scale. The proportion of patients with 30-day grade III or higher organ toxicity will be reported together with the corresponding 95% Bayesian credible interval.
Secondary Outcome Measures
- Time to platelet and neutrophil engraftment [Up to 1 year post transplant]
Will be calculated and illustrated from the time of transplant by the method of Kaplan and Meier.
- Incidence of acute graft versus host disease (aGVHD) [At 100 days post transplant]
The 100-day rates of acute with the competing risk of relapse will be estimated using the method of Gooley.
- Incidence of chronic GVHD [At 100 days post transplant]
The 100-day rates of chronic GVHD with the competing risk of relapse will be estimated using the method of Gooley
- Incidence of chronic GVHD [At 1 year post transplant]
The 1 year rates of chronic GVHD with the competing risk of relapse will be estimated using the method of Gooley.
- Rate of grade II organ toxicity [Up to 100 days post transplant]
The 100-day rates of grade II organ toxicity will be reported as counts with percentages.
- Rate of graft failure (primary and secondary) [Up to 100 days post transplant]
The 100-day rates of primary and secondary graft failure will be reported as counts with percentages.
