Trial Summary

What is the purpose of this trial?

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.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, it mentions that patients must have fully recovered from the effects of prior treatments before joining the study, which might imply some medications need to be paused. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the drug Zoledronic acid in combination with stem cell transplant for pediatric blood cancers?

Research shows that using Zoledronic acid after a specific type of stem cell transplant in children with high-risk acute leukemia can lower the chances of complications like graft-versus-host disease and improve survival rates. Patients who received three or more doses of Zoledronic acid had better outcomes, including higher survival rates and lower transplant-related mortality.12345

Is the combination of stem cell transplant and Zometa safe for pediatric blood cancer patients?

The studies suggest that haploidentical stem cell transplantation (a type of stem cell transplant using a partially matched donor) is generally safe, with low toxicity and no transplant-related deaths reported in pediatric patients with solid tumors. However, specific safety data for the combination with Zometa (also known as Zoledronic acid) in pediatric blood cancers is not provided in these studies.12678

How is the treatment TCRαβ+/CD19+ depleted Haploidentical HSCT with Zometa unique for pediatric blood cancers?

This treatment is unique because it combines a specialized stem cell transplant that removes specific immune cells (TCRαβ+ and CD19+ cells) with Zometa (a drug that strengthens bones), potentially reducing complications like graft-versus-host disease and improving outcomes for children with blood cancers.1291011

Eligibility Criteria

This trial is for pediatric patients with high-risk or relapsed blood cancers and solid tumors who have a suitable haploidentical donor. It's not open to those pregnant, breastfeeding, with uncontrolled infections, prior organ transplants, or conditions that could affect study participation.

Inclusion Criteria

I have blood cancer and either can't find a matching donor or can't wait for one without my disease getting worse.
My AML is not responding to treatment and my bone marrow has less than 20% cancer cells.
Inclusion Criteria for Donors: Donor must be 18 years of age minimum, 65 years of age maximum Donor must be in good general health as determined by evaluating medical provider Must meet donor criteria for human cells, tissues, and cellular and tissue-based products per Code of Federal Regulations 21 CFR 1271, subpart C. Specifically: Donor screening in accordance with 1271.75 indicates that the donor: Is free from risk factors for, and clinical evidence of, infection due to relevant communicable disease agents and diseases; and Is free from communicable disease risks associated with xenotransplantation; and The results of donor testing for relevant communicable disease agents in accordance with 1271.80 and 1271.85 are negative or nonreactive, except as provided in 1271.80(d)(1). Haploidentical by HLA-typing Preference will be given to donors who demonstrate KIR incompatibility with recipient HLA class I ligands defined as the donor expressing a KIR gene for which the corresponding HLA class I ligand is not expressed by the recipient. Negative testing for relevant communicable diseases: Hepatitis B surface antigen (HBsAg) Hepatitis B core antibody (Anti-HBc) Hepatitis C antibody (Anti-HCV) HIV 1 & 2 antibody (Anti-HIV-1, 2 plus O) HTLV I/II antibody (Anti-HTLV I/II) RPR (Syphilis TP) CMV (Capture CMV) MPX for: HepB (HBV-PCR), HepC (HCV-PCR), HIV (HIV-PCR) NAT for West Nile Virus (WNV-PCR) T.

Treatment Details

Interventions

  • TCRαβ+/CD19+ depleted Haploidentical HSCT
  • Zoledronate
Trial OverviewThe trial tests a transplant using stem cells from a half-matched donor that are filtered to remove certain immune cells (TCRαβ+/CD19+), combined with Zoledronate post-transplant. This Phase I study aims to assess the safety of this approach.

Experimental Treatment
Group I: TCRαβ+/CD19+ depleted Haploidentical HSCT+ ZoledronateExperimental Treatment2 Interventions
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.

Findings from Research

In a study of 168 patients with refractory/relapsed B-cell acute lymphoblastic leukemia, those who received haploidentical hematopoietic stem cell transplantation (haplo-HSCT) after CAR-T therapy had similar long-term survival rates compared to those who underwent haplo-HSCT after achieving minimal residual disease-negative complete remission from chemotherapy.
Patients who achieved a first complete remission (CR1) after chemotherapy had better overall survival and leukemia-free survival rates than those who had a second or more complete remission (≥CR2), highlighting the importance of achieving an earlier remission for better transplant outcomes.
Comparable outcomes in patients with B-cell acute lymphoblastic leukemia receiving haploidentical hematopoietic stem cell transplantation: Pretransplant minimal residual disease-negative complete remission following chimeric antigen receptor T-cell therapy versus chemotherapy.Yang, TT., Meng, Y., Kong, DL., et al.[2022]
In a pilot study involving 6 pediatric patients with relapsed metastatic tumors, transplantation of haploidentical T and B cell depleted grafts with high NK cell counts showed feasibility and low toxicity, with primary engraftment achieved in all patients.
Despite significant tumor burden before transplantation, the approach resulted in rapid hematopoietic recovery and no transplant-related mortality, suggesting potential for further development in posttransplant immunomodulation strategies.

In a study of 27 children undergoing haploidentical hematopoietic stem cell transplantation, γδ T cells were found to be the main T-cell type shortly after the procedure, indicating their importance in early immune responses post-transplant.
The research highlighted that Vδ1 γδ T cells expanded in patients with cytomegalovirus reactivation and showed strong cytotoxic activity against leukemia cells, suggesting potential for targeted therapies using zoledronic acid to enhance these cells' effectiveness against cancer.
