NCT03734601

Brief Summary

The purpose of this study is to evaluate whether addition of a low dose of total body irradiation (TBI) to a standard preparation for transplant \[total lymphoid irradiation (TLI) and anti-thymocyte globulin (ATG)\] conditioning will help to augment donor chimerism without reducing tolerability of this regimen or increasing the risk of graft-vs-host disease (GVHD)

Outcome Measures

Primary Outcomes (1)

  • Full-dose Donor Chimerism (FDC) at Day 28 Following TLI/ATG/TBI Conditioning.

    Subsequent to TLI/ATG/TBI conditioning, the proportion of participants with full dose donor chimerism (FDC) will be determined by Day 28. FDC is defined as achieving ≥ 95% donor type in the CD3+ lineage within 28 days of donor cell infusion, as assessed by short tandem repeat (STR) testing. The outcome will be expressed as the number of participants that achieve FDC by Day 28, a number without dispersion.

  • Event-free Survival (EFS) at 1 Year

Study Arms (1)

TBI+TLI

EXPERIMENTAL

TBI, single exposure on Day -1, 80 centigray (cGy) in addition to total lymphoid irradiation (TLI, 120 cGy/day for 9 days, weekends excluded) and anti-thymocyte globulin (ATG) 1.5 mg/kg (conditioning regimen)

Radiation: Total body irradiation (TBI)Drug: Anti-thymocyte globulin (ATG)Drug: TacrolimusDrug: Mycophenolate mofetil (MMF)Radiation: Total lymphoid irradiation (TLI)

Interventions

Administer Total body irradiation (TBI) 80 cGy on Day 1 of standard TLI ATG conditioning

TBI+TLI

Given intravenous (IV), Dose 1.5 mg/kg x 5 days

TBI+TLI

Oral, Dose 0.05 mg/kg twice daily, can be given intravenous (IV)

Also known as: Fujimycin
TBI+TLI

Given Oral, 15 mg/k every 2 hours for peripheral blood stem cells (PBSC) from matched related donors; 15 mg/kg every 8 hours for PBSC from unrelated donors (URDs) or mismatched related donors.

Also known as: Cellcept, MMF
TBI+TLI

9 x 120 cGy over 11 days

TBI+TLI

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Has a human leukocyte antigen (HLA)-matched or single allele mismatched adult sibling donor or unrelated donor.
  • Acute myeloid leukemia (AML); myelodysplastic syndrome (MDS); myeloproliferative disease syndrome (MPD)\]; chronic lymphocytic leukemia (CLL); B- or T-cell non Hodgkin lymphoma (NHL); Hodgkin lymphoma (HL); or chronic myelomonocytic leukemia (CMML), suitable for treatment with allogeneic transplant after TLI and ATG reduced intensity conditioning.
  • Considered at high-risk for regimen-related toxicity from fully-ablative transplant conditioning (therefore reduced-intensity conditioning is recommended).
  • Ability to understand and the willingness to sign a written informed consent document. Patients must have signed informed consent to participate in the trial.

You may not qualify if:

  • Uncontrolled bacterial, viral or fungal infection defined as currently taking medication and progression of clinical symptoms.
  • Progressive hemato lymphoid malignancy despite conventional therapy.
  • Chronic myelogenous leukemia (CML).
  • Active CNS involvement of the underlying malignancy.
  • HIV positive
  • Pregnant or lactating
  • Prior malignancy (EXCEPTION: diagnosed \> 5 years ago without evidence of disease, OR treated ≤ 5 years ago but have a greater than 50% chance of life expectancy of ≥ 5 years for that malignancy).
  • Have a psychiatric disorder(s) or psychosocial circumstance(s) which in the opinion of the primary physician would place the patient at an unacceptable risk from transplant.
  • Left ventricular ejection fraction (LEVF) \< 30%, or uncontrolled cardiac failure
  • Diffusing capacity of lung for carbon monoxide (DLCO) \< 40% predicted
  • Total bilirubin \> 3 mg/dL
  • Serum glutamic oxaloacetic transaminase (SGOT) or serum glutamic-pyruvic transaminase (SGPT) \> 4 x upper limit of normal (ULN)
  • Creatinine \> 2 mg/dL and an estimated creatinine clearance \< 40 mL/min
  • Poorly-controlled hypertension despite multiple antihypertensive medications
  • Karnofsky Performance Status (KPS) \< 60%
