Provision of TCRγδ T Cells and Memory T Cells Plus Selected Use of Blinatumomab in Naïve T-cell Depleted Haploidentical Donor Hematopoietic Cell Transplantation for Hematologic Malignancies Relapsed or Refractory Despite Prior Transplantation

Brief summary (registry, in English)
This study seeks to examine treatment therapy that will reduced regimen-related toxicity and relapse while promoting rapid immune reconstitution with limited serious graft-versus-host-disease (GVHD) and also improve disease-free survival and quality of life. The investigators propose to evaluate the safety and efficacy of selective naive T-cell depleted (by TCRɑβ and CD45RA depletion, respectively) haploidentical hematopoietic cell transplant (HCT) following reduced intensity conditioning regimen that avoids radiation in patients with hematologic malignancies that have relapsed or are refractory following prior allogeneic transplantation. PRIMARY OBJECTIVE: * To estimate engraftment by day +30 post-transplant in patients who receive TCRɑβ-depleted and CD45RA-depleted haploidentical donor progenitor cell transplantation following reduced intensity conditioning regimen without radiation. SECONDARY OBJECTIVES: * Assess the safety and feasibility of the addition of Blinatumomab in the early post-engraftment period in patients with CD19+ malignancy. * Estimate the incidence of malignant relapse, event-free survival, and overall survival at one-year post-transplantation. * Estimate incidence and severity of acute and chronic (GVHD). * Estimate the rate of transplant related mortality (TRM) in the first 100 days after transplantation.

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Who the study is looking for
- Age less than or equal to 21 years.
- Any of the following hematologic malignancies that has relapsed or remains refractory after prior allogeneic HCT (this includes any stage of disease - such as refractory due to induction failure, refractory in relapse, or in any CR - as long as the hematologic malignancy remained persistent or returned after a previous allogeneic HCT):
- ALL, AML, Myeloid Sarcoma, CML, Juvenile myelomonocytic leukemia (JMML), myelodysplastic syndrome (MDS), non-Hodgkin lymphoma (NHL)
- Has a suitable single haplotype matched (≥ 3 of 6) family member donor.
- Does not have any other active malignancy other than the one for which this transplant is indicated.
- If prior CNS leukemia, it must be treated and in CNS CR
- Does not have current uncontrolled bacterial, fungal, or viral infection.
- There is no minimum time from the previous transplant, but patients must meet the following criteria:
- Left ventricular ejection fraction \> 40%, or shortening fraction ≥ 25%.
- Creatinine clearance (CrCl) or glomerular filtration rate (GFR) ≥ 50 ml/min/1.73m2.
- Forced vital capacity (FVC) ≥ 40% of predicted value; or pulse oximetry ≥ 92% on room air if patient is unable to perform pulmonary function testing.
- Karnofsky or Lansky (age-dependent) performance score ≥ 50 (See Appendix A).
- Bilirubin ≤ 3 times the upper limit of normal for age.
- Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤ 5 times the upper limit of normal for age.
- Not pregnant. If female with child bearing potential, must be confirmed by negative serum or urine pregnancy test within 14 days prior to enrollment.
- Not breast feeding
- At least single haplotype matched (≥ 3 of 6) family member
- At least 18 years of age.
- HIV negative.
- Not pregnant as confirmed by negative serum or urine pregnancy test within 14 days prior to enrollment (if female).
- Not breast feeding.
- Regarding donation eligibility, is identified as either:
- Completed the process of donor eligibility determination as outlined in 21 CFR 1271 and agency guidance; OR
- Does not meet 21 CFR 1271 eligibility requirements, but has a declaration of urgent medical need completed by the principal investigator or physician sub-investigator per 21 CFR 1271.
