Alpha/Beta CD19+ Depleted Haploidentical Transplantation + Zometa for Pediatric Hematologic Malignancies and Solid Tumors

Study Purpose

This phase I trial studies the safety of transplantation with a haploidentical donor peripheral blood stem cell graft depleted of TCRαβ+ cells and CD19+ cells in conjunction with the immunomodulating drug, Zoledronate, given in the post-transplant period to treat pediatric patients with relapsed or refractory hematologic malignancies or high risk solid tumors.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 7 Months - 21 Years

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

CONDITIONING REGIMENS: Patients with high-risk leukemia will receive myeloablative conditioning with anti-thymocyte globulin intravenously (IV) over 4-6 hours on days -12 through -9, Fludarabine IV over 30 minutes on days -8 through -5, Thiotepa IV every every 12 hours on day -4 and Total Body Irradiation (TBI) on days -3 through -1. All other patients receive reduced intensity conditioning consisting of anti-thymocyte globulin intravenously (IV) over 4-6 hours on days -12 through -9, fludarabine IV over 30 minutes on days -8 through -5, thiotepa IV over 4 hours every 12 hours on day -4, and melphalan IV on days -3 and -2. PERIPHERAL BLOOD STEM CELL TRANSPLANTATION: Patients undergo TCR-alpha/beta+ and CD19+ depleted KIR/KIR ligand-mismatched haploidentical donor peripheral blood stem cell transplantation on day 0. If the graft contains less than 4 x 10^6 CD34+ cells/kg, a second HSC graft may be administered. PROPHYLAXIS FOR GVHD: Patients receiving a graft containing > 25 x 10^3 CD3+ TCR alpha/beta+ cells receive mycophenolate mofetil IV twice daily over 2 hours on days 1 to 30 with a rapid taper. Patients with TCR alpha/beta+ cells exceeding 100,000/kg also receive tacrolimus IV continuously or orally (PO) every 12 hours on days 0-90 with a taper at the discretion of the Principal Investigator. ZOLEDRONATE ADMINISTRATION: Patients will receive five doses of Zoledronate (IV) at 28 day intervals beginning on Day +28 post-HSCT. Follow-up assessments will occur after transplantation.

Arms & Interventions


Experimental: TCRαβ+/CD19+ depleted Haploidentical HSCT+ Zoledronate

Patients with high-risk leukemia (who are at least one year of age and who have not received TBI as conditioning for a previous HSCT) will receive myeloablative conditioning with ATG, Fludarabine, Thiotepa, and TBI. All other subjects will undergo a reduced-intensity conditioning regimen consisting of ATG, Fludarabine, Thiotepa, and Melphalan prior to transplant with a KIR/KIR ligand mismatched haploidentical donor peripheral blood stem cell graft depleted of TCR-αβ+ and CD19+ cells. Patients will receive 5 doses of zoledronate (at 28 day intervals) starting 28 days after stem cell transplant.


Procedure: - TCRαβ+/CD19+ depleted Haploidentical HSCT

Patients with high-risk leukemia will receive myeloablative conditioning. All other patients will undergo a reduced-intensity conditioning with ATG, Fludarabine, Thiotepa and Melphalan followed by transplant with a KIR/KIR (Killer cell immunoglobulin-like recetptor) ligand mismatched haploidentical donor peripheral blood stem cell graft depleted of TCRab+ cells and CD19+ cells using the CliniMACS System.

Drug: - Zoledronate

Given IV. Patients will receive five doses of Zoledronate (each 1.25 mg/m2 at a 28 day interval) following transplant.
