Code:

NCT03509961

Conditions

B-cell Acute Lymphoblastic Leukemia

Eligibility Criteria

Sex: All

Age: 1 - 25

Healthy Volunteers: Not accepted

Interventions

NGS-MRD

Myeloablative allogeneic HCT with a non-TBI conditioning regimen

Study Details

Brief summary:

This study will evaluate the use of non- TBI (total body irradiation) conditioning for B-ALL patients with low risk of relapse as defined by absence of NGS-MRD (next generation sequencing minimal residual disease) before receiving a hematopoietic cell transplant (HCT). Patients diagnosed with B-ALL who are candidates for HCT will be screened by NGS-MRD on a test of bone marrow done before the HCT. Subjects who are pre-HCT NGS-MRD negative will be eligible to receive a non-TBI conditioning regimen as part of the treatment cohort of the study. Subjects who are pre-HCT NGS-MRD positive will be treated as per treating center standard and will be followed in an observational cohort (HCT center standard of care).

Eligibility Criteria

Sex: All

Age: 1 - 25

Healthy Volunteers: Not accepted

Inclusion Criteria for the Observational Arm:

Any patient with ALL who undergoes Myeloablative HCT including any of the following:

  • Patients who are pre-HCT NGS-MRD positive.
  • Patients <1 year old who are pre-HCT NGS-MRD negative.
  • Patients who are pre-HCT NGS-MRD negative (CR1/CR2) who received inotuzumab ozogamicin therapy before proceeding to HCT.
  • Patients who are pre-HCT NGS-MRD negative and will be receiving haploidentical HCT.
  • Patients who are pre-HCT NGS-MRD negative in CR2 with history of CNS relapse.
  • Patients who have received blinatumomab, but are >CR2 prior to HCT.
  • Patients who have received CART-T cellular therapy, but are >CR2 prior to HCT.
  • Patients with pre-HCT NGS-MRD negative in ≥ CR3.
  • Any T-ALL and MPAL patients undergoing first allogeneic HCT
  • Any patient who is pre-HCT NGS-MRD negative and eligible for participation in the treatment arm but family does not consent for treatment arm or treating physician believe it is in the patient best interest not to enroll on the treatment arm

Inclusion Criteria for the Treatment Arm:

  • Pre-HCT NGS-MRD negative
  • Age ≥ 1 year and ≤ 25 years
  • Disease status: B-ALL in first (CR1) or second remission (CR2)
  • No prior allogeneic hematopoietic stem cell transplant.
  • Patients in CR1 or CR2 after blinatumomab treatment.
  • Patients in CR1 or CR2 after CAR-T cellular therapy.
  • Karnofsky Index or Lansky Play-Performance Scale ≥ 60 % on pre-transplant evaluation. Karnofsky scores must be used for patients > 16 years of age and Lansky scores for patients < 16 years of age.
  • Able to give informed consent if > 18 years, or with a legal guardian capable of giving informed consent if < 18 years.
  • Adequate organ function (within 4 weeks of initiation of preparative regimen), defined as:
  • Pulmonary: FEV1, FVC, and corrected DLCO must all be ≥ 50% of predicted by pulmonary function tests (PFTs). For children who are unable to perform for PFTs due to age, the criteria are: no evidence of dyspnea at rest and no need for supplemental oxygen.
  • Renal: Creatinine clearance or radioisotope GFR ≥ 60 mL/min/1.73 m2 or a serum creatinine based on age/gender.
  • Cardiac: Shortening fraction of ≥ 27% by echocardiogram or radionuclide scan (MUGA) or ejection fraction of ≥ 50% by echocardiogram or radionuclide scan (MUGA), choice of test according to local standard of care.
  • Hepatic: SGOT (AST) or SGPT (ALT) < 5 x upper limit of normal (ULN) for age. Conjugated bilirubin < 2.5 mg/dL, unless attributable to Gilbert's Syndrome.

Exclusion Criteria:

  • CR2: exclude patients with history of CNS relapse (i.e. in CR2 with history of CNS isolated or combined relapse; CNS 2 will also be considered as CNS 3 for this purpose) from the treatment arm of study (can be enrolled on the observational arm).
  • Patients who have received inotuzumab treatment prior to allogeneic HCT are NOT eligible for the study treatment arm. Inotuzumab treatment may increase the risk of VOD/SOS for any allogeneic HCT recipient, but could potentiate the risk for with busulfan-based myeloablation (study-directed non-TBI conditioning). All inotuzumab-treated patients are eligible for the observational arm (HCT center standard of care).
  • Patients receiving non-myeloablative conditioning are not allowed on the observational arm (reduced toxicity conditioning with Flu/Mel/Thio is allowed on the observational arm).
  • Pregnant or lactating females are ineligible as many of the medications used in this protocol could be harmful to unborn children and infants.
  • Patients with HIV or uncontrolled fungal, bacterial or viral infections are excluded. Patients with history of fungal disease during induction therapy may proceed if they have a significant response to antifungal therapy with no evidence or minimal evidence of non-progressive disease remaining by CT evaluation.
  • Patients with active CNS leukemia or any other active site of extramedullary disease at the time of enrollment are not permitted.
  • T-ALL and MPAL patients are only allowed on the observational arm.
  • Patients with genetic disorders (generally marrow failure syndromes) prone to secondary AML/ALL with known poor outcome are not eligible (Fanconi Anemia, Kostmann Syndrome, Dyskeratosis Congenita, etc).

Interventions and Outcome Measures

Arms

other: Observational Arm

Patients are enrolled to the observational arm to proceed with NGS-MRD testing pre-HCT. If NGS-MRD negative, eligible patients may be considered for the Treatment Arm to receive a myeloablative non-TBI conditioning regimen prior to HCT.

If NGS-MRD positive, patients may continue in the observational arm and receive HCT under the direction of their transplant physician and followed on the study for outcome.

other: Treatment Arm

Patients enrolled to the observational arm that are NGS-MRD pre-HCT are considered for the Treatment Arm. Patients will receive a myeloablative non-TBI conditioning regimen prior to the transplant consisting on busulfan, fludarabine and thiotepa. Patients will be followed for outcome for up to 5 years.

Interventions

NGS-MRD

Next generation sequencing minimal residual disease (NGS-MRD) is a test that has increased sensitivity over multichannel flow cytometry to better identify risk of key outcomes after HCT. Patients that have a pre-HCT negative NGS-MRD results may be eligible to proceed to the treatment arm of the study that uses a non-TBI conditioning regimen.

Myeloablative allogeneic HCT with a non-TBI conditioning regimen

Myeloablative study regimen will consist of busulfan, fludarabine and thiotepa.

day -7: Fludarabine and Busulfan day -6: Fludarabine and Busulfan day -5: Fludarabine and Busulfan day -4: Fludarabine and Busulfan day -3: Fludarabine day -2: Thiotepa day -1: Rest Day 0: Transplant

Primary outcome measure

  • Two Year Event-free Survival [ Time Frame: Two years ]
