HLA-Mismatched Unrelated Donor Bone Marrow Transplantation With Post-Transplantation Cyclophosphamide
Myelodysplastic Syndrome (MDS), Chronic Lymphocytic Leukemia (CLL), Chemotherapy-sensitive Lymphoma
About this trial
This is an interventional treatment trial for Myelodysplastic Syndrome (MDS)
Eligibility Criteria
Inclusion Criteria:
- Age ≥ 15 years and < 71 years at the time of signing the informed consent form
- Partially HLA-mismatched unrelated donor: HLA typing will be performed at high resolution (allele level) for the HLA-A, -B, -C, and -DRB1 loci; a minimum match of 4/8 at HLA-A, -B, -C, and -DRB1 is required
- Product planned for infusion is bone marrow
Disease and disease status:
- Acute Leukemias or T lymphoblastic lymphoma in 1st or subsequent complete remission (CR): Acute lymphoblastic leukemia (ALL)/T lymphoblastic lymphoma; acute myelogenous leukemia (AML); acute biphenotypic leukemia (ABL); acute undifferentiated leukemia (AUL)
- Myelodysplastic Syndrome (MDS), fulfilling the following criteria: Subjects with de novo MDS who have or have previously had Intermediate-2 or High risk disease as determined by the International Prognostic Scoring System (IPSS). Current Intermediate-2 or High risk disease is not a requirement; Subjects must have < 20% bone marrow blasts, assessed within 60 days of informed consent; Subjects may have received prior therapy for the treatment of MDS prior to enrollment
- Chronic Lymphocytic Leukemia (CLL) in CR if RIC is to be used; in CR or partial response (PR) if FIC is to be used
- Chronic myeloid leukemia (CML) in 1st or subsequent chronic phase characterized by <10% blasts in the blood or bone marrow.
- Chemotherapy-sensitive lymphoma in status other than 1st CR
- Performance status: Karnofsky or Lansky score ≥ 60% (Appendix A)
Adequate organ function defined as:
- Cardiac: left ventricular ejection fraction (LVEF) at rest ≥ 35% (RIC cohort) or LVEF at rest ≥ 40% (FIC cohort), or left ventricular shortening fraction (LVFS) ≥ 25%
- Pulmonary: diffusing capacity of the lungs for carbon monoxide (DLCO), forced expiratory volume (FEV1), forced vital capacity (FVC) ≥ 50% predicted by pulmonary function tests (PFTs)
- Hepatic: total bilirubin ≤ 2.5 mg/dL, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) < 5 x upper limit of (ULN) (unless disease related)
- Renal: serum creatinine (SCr) within normal range for age (see table 2.3). If SCr is outside normal range for age, creatinine clearance (CrCl) > 40 mL/min/1.73m2 must be obtained (measured by 24-hour (hr) urine specimen or nuclear glomerular filtration rate (GFR), or calculated GFR (by Cockcroft-Gault formula for those aged ≥ 18 years; by Original Schwartz estimate for those < 18 years))
- Subjects ≥ 18 years of age must have the ability to give informed consent according to applicable regulatory and local institutional requirements. Legal guardian permission must be obtained for subjects < 18 years of age. Pediatric subjects will be included in age appropriate discussion in order to obtain assent.
Subjects with documentation of confirmed HIV-1 infection (i.e. HIV-positive), and a hematologic malignancy who meets all other eligibility requirements must:
- Receive only RIC regimen (i.e. Regimen A)
- Be willing to comply with effective antiretroviral therapy (ARV)
- Have achieved a sustained virologic response for 12 weeks after cessation of hepatitis C antiviral treatment (in HIV-positive subjects with hepatitis C)
Exclusion Criteria:
- HLA-matched related or 8/8 allele matched (HLA-A, -B, -C, -DRB1) unrelated donor available. This exclusion does not apply to HIV-positive subjects who have a CCR5delta32 homozygous donor.
- Autologous HCT < 3 months prior to the time of signing the informed consent form
- Females who are breast-feeding or pregnant
HIV-positive subjects:
- Acquired immunodeficiency syndrome (AIDS) related syndromes or symptoms that may pose an excessive risk for transplantation-related morbidity as determined by the Treatment Review Committee (see Appendix D).
- Untreatable HIV infection due to multidrug ARV resistance. Subjects with a detectable or standard viral load > 750 copies/mL should be evaluated with an HIV drug resistance test (HIV-1 genotype). The results should be included as part of the ARV review (described in Appendix D).
- May not be currently prescribed ritonavir, cobacistat and/or zidovudine
- Current uncontrolled bacterial, viral or fungal infection (currently taking medication with evidence of progression of clinical symptoms or radiologic findings)
- Prior allogeneic HCT
- History of primary idiopathic myelofibrosis
- MDS subjects may not receive RIC and must be < 50 years of age at the time of signing the informed consent form
