NCT04375631

Brief Summary

This phase I trial studies the best dose of total body irradiation when given with cladribine, cytarabine, filgrastim, and mitoxantrone (CLAG-M) or idarubicin, fludarabine, cytarabine and filgrastim (FLAG-Ida) chemotherapy reduced-intensity conditioning regimen before stem cell transplant in treating patients with acute myeloid leukemia, myelodysplastic syndrome, or chronic myelomonocytic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Giving chemotherapy and total body irradiation before a donor peripheral blood stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. When the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets and may help destroy any remaining cancer cells. Sometimes the transplanted cells from a donor can attack the body's normal cells called graft versus host disease. Giving cyclophosphamide, cyclosporine, and mycophenolate mofetil after the transplant may stop this from happening.

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age \>= 18 years with an Hematopoietic Cell Transplantation-Comorbidity Index (HCT-CI) =\< 5 for patients over 60 years -(Enrollment of patients \>= 75 years of age will require case presentation at the transplant Patient Care Conference (PCC) and approval by consensus)
  • Acute myeloid leukemia (AML) (2016 World Health Organization \[WHO\] criteria) that is either primary refractory (as defined by failure of 2 cycles of 7+3-like chemotherapy, 1 cycle of high-dose cytarabine-based chemotherapy, or at least 2 cycles of venetoclax in combination with other therapies), or is in untreated or unsuccessfully treated first or subsequent relapse. Patients in morphological remission (i.e. \< 5% blasts in the bone marrow) but evidence of minimal residual disease (MRD) by multiparameter flow cytometry, cytogenetics/fluorescence in situ hybridization (FISH), or molecular means will be eligible for trial participation. Patients with relapsed or refractory acute leukemia of ambiguous lineage (acute undifferentiated leukemia, mixed phenotype acute leukemia) that is either primary refractory or is in untreated or unsuccessfully treated first or subsequent relapse are also eligible
  • Subjects with previously treated myelodysplastic syndrome (MDS) and chronic myelomonocytic leukemia (CMML), defined as prior treatment with at least one hypomethylating agent (HMA; azacitidine and/or decitabine) whose disease progressed, relapsed, or was refractory to HMA treatment as follows: 1) patients who have failed at least 4 cycles of monotherapy with azacitidine or decitabine, 2) patients who received at least 2 cycles of HMA in combination with another therapeutic agent. Subjects with MDS and CMML who failed at least 1 cycle of induction chemotherapy will be also eligible
  • The use of hydroxyurea prior to initiation of study treatment is allowed. Patients with symptoms/signs of hyperleukocytosis, WBC \> 100,000/uL or with concern for other complications of high tumor burden (e.g. disseminated intravascular coagulation) can be treated with leukapheresis or may receive up to 2 doses of cytarabine (up to 500 mg/m\^2 per dose) prior to start of study treatment
  • Karnofsky score \>= 70; Eastern Cooperative Oncology Group (ECOG) 0-1
  • Adequate cardiac function defined as absence of decompensated congestive heart failure and/or uncontrolled arrhythmia and left ventricular ejection fraction \>= 45%
  • Bilirubin =\< 2.5 x institutional upper limit of normal unless elevation is thought to be due to hepatic infiltration by AML, Gilbert's syndrome, or hemolysis
  • Adequate pulmonary function defined as absence of oxygen (O2) requirements and either carbon monoxide diffusing capability test (DLCO) correct \>= 70% mmHg or DLCO corrected 60-69% mmHg and partial pressure of oxygen (pO2) \>= 70 mmHg
  • Serum creatinine =\< 1.5 mg/dL
  • Prior autologous HCT is permissible if relapse occurred \> 3 months but =\< 6 months after HCT
  • Prior TBI-containing allogeneic HCT up to 3 Gy is permissible if \> 6 months after HCT
  • A human leukocyte antigen (HLA)-matched or near-matched related, unrelated or haploidentical donor for collection of stimulated peripheral blood stem cells or HLA-matched or near-matched cord blood unit must be identified and readily available
  • Women of childbearing potential and men must agree to use adequate contraception beginning at the signing of the consent until at least 12 months post-transplant
  • Patients may have previously received chemotherapy with a mitoxantrone, idarubicin- or cladribine/fludarabine-based regimen for MDS or AML. If the patient has received CLAG-M or FLAG-Ida before and has been sensitive to this regimen, eligibility will be determined on a case-by-case basis by the study principal investigator (PI)
  • Ability to understand and sign a written informed consent document (or legal representative)
  • +18 more criteria

You may not qualify if:

  • Patients \>= 18 years being treated at Seattle Children's Hospital
  • Active central nervous system (CNS) disease
  • Concomitant illness associated with a likely survival of \< 1 year
  • Active systemic fungal, bacterial, viral, or other infection, unless disease is under treatment with anti-microbials and/or controlled or stable. Patients with fever thought to be likely secondary to myeloid malignancy are eligible
  • Known hypersensitivity or contraindication to any study drug used in this trial
  • Pregnancy or lactation
  • Concurrent treatment with any other approved or investigational anti-leukemia agent
  • Since detection of anti-donor-specific antibodies (anti-DSA) is associated with higher graft rejection rate, patients will be screened for anti-DSA pre-transplant. Patient with DSA mean fluorescent intensity (MFI) \<5000 after desensitization treatment, will be considered eligible to participate in the study.
