Adoptive Transfer of Haplo-identical DLI for AML and MDS

Phase 2CompletedNCT02046122

Duke University19 enrolled

Overview

The primary hypothesis is that chemotherapy followed by donor lymphocyte infusion (DLI) from HLA-haploidentical donors is a safe procedure that will not cause Graft versus Host Disease (GVHD) or increased treatment-related mortality. The Investigator further believes that this will improve outcomes of elderly patients with high-risk AML or MDS compared to chemotherapy alone, and that that this benefit will be even greater in donor-recipient pairs that share maternal-fetal microchimerism or non-inherited maternal antigen (NIMA) mismatch. A large part of this trial will include immune function assays as well as assessments of efficacy, toxicity, and GVHD. Because this therapy may be a tolerable alternative to allogeneic hematopoietic stem cell transplantation (alloHSCT) for elderly patients, the Investigator will validate functional measurements (e.g. Comprehensive Geriatric Assessment (CGA)) with biologic correlates (cytokine and genomic profiles) and clinical outcomes.

Interventions

IdarubicinDRUG

Eligible subjects will receive induction chemotherapy with idarubicin (12 mg/m2 intravenously for 3 days) and cytarabine (100 mg/m2 intravenously for 7 days) starting Day 1 and ending Day 7. Patients 80 years or older will only receive 2 and 5 days of idarubicin and cytarabine respectively starting Day 1 and ending Day 5. Subjects who experience no remission or partial remission will receive a second course of the identical induction chemotherapy.

CytarabineDRUG

Cytarabine (100 mg/m2 intravenously for 7 days) starting Day 1 and ending Day 7. Patients 80 years or older will only receive 2 and 5 days of idarubicin and cytarabine respectively starting Day 1 and ending Day 5. Subjects who achieve a complete remission (CR) will receive 2 further courses of cytarabine postremission chemotherapy (consolidation) at 1.0 g/m2 for 6 dosages followed by HLA-mismatched DLI after the second consolidation.

DLIBIOLOGICAL

HLA-mismatched DLI will be administered Day 9, approximately 24-48 hours following completion of chemotherapy at a dose of 1x10\^8 cluster of differentiation 3 (CD3+) cells; however, due to logistics of planning infusions with staffing, donor availability, weekends/holidays, etc., it may be necessary to postpone cell infusion up to 96 hours. Given the time constraints presented by the need to start induction chemotherapy as soon as possible, in some cases, it may not be logistically possible to administer cells with induction. In these cases, patients would just receive standard induction chemotherapy and cells would be administered after consolidation 1 in addition to consolidation 2 Subjects who achieve a CR will receive 2 further courses of cytarabine postremission chemotherapy (consolidation) at 1.0 g/m2 for 6 dosages followed by HLA-mismatched DLI after the second consolidation.

Eligibility

Sex: ALLMin age: 55 Years

Medical Language ↔ Plain English

Inclusion Criteria: 1. Subjects must have their diagnosis of high-risk AML or high-risk MDS confirmed by pathologic review of bone marrow biopsy according to WHO guidelines 2. Patients will be defined as high risk AML and thus eligible if they meet one or more of the following criteria: 1. Secondary AML (from underlying MDS or therapy related) 2. Presence of complex cytogenetic abnormalities (3 or more cytogenetic abnormalities), all monosomies, del 5q, del 7q, inv3, t(3;3), t(6;9), t(9;22), abn 11q23 (excluding t(9;11)) 3. Fms-like tyrosine kinase 3 (FLT3)-internal tandem duplication (ITD) mutation positive 4. Age ≥ 65 years given poor outcomes even with favorable cytogenetics 3. Patients will be defined as high risk MDS and thus eligible if they have a MD Anderson Comprehensive Cancer MDS Risk Score ≥9 4. Subjects must have Eastern Cooperative Oncology Group (ECOG) Performance status of 0,1,or 2; if ECOG 2, they must also have a Charlson comorbidity index of ≤5. 5. Subjects must be 55 years of age or older 6. Subjects should have a 3-5/6 HLA-matched related haploidentical donor who is evaluated and deemed able to provide DLI. 7. Patient should be able to provide informed consent 8. Subjects must have a multigated acquisition (MUGA) and /or ECHO or cardiac magnetic resonance imaging (MRI). The required minimum standards include MUGA or ECHO or cardiac MR showing an ejection fraction( EF) of 40%. Those with an EF 40-49% must also have a cardiologist consult and assist with management. 9. Pulmonary function tests (PFTs) with diffusing capacity of lung for carbon monoxide (DLCO) are conditional for subjects at the discretion of the physician. The required minimum standards for those who have PFTs include DLCO of 40%. Those with DLCO of 40-49% must have a pulmonologist consult and assist with management. 10. Subjects of all genders and races are eligible Exclusion Criteria: 1. Pregnant or lactating women. 2. Patients with other major medical or psychiatric illnesses which the treating physician feels could seriously compromise tolerance to this protocol 3. Patients with known active central nervous system (CNS) disease 4. Patients with acute promyelocytic leukemia (FAB M3)
