Hypomethylating Agents and Venetoclax for Acute Myeloid Leukemia Relapsed After Hematopoietic Stem Cell Transplant. CLINICAL LYMPHOMA, MYELOMA & LEUKEMIA 2024; 24:400-406. [PMID: 38429222 DOI: 10.1016/j.clml.2024.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 02/07/2024] [Accepted: 02/08/2024] [Indexed: 03/03/2024]
Abstract
BACKGROUND Hypomethylating agent + venetoclax is an effective frontline combination for acute myeloid leukemia, but its efficacy and safety in post-allogeneic hematopoietic cell transplant (alloHCT) relapse remain underexplored. Outcomes have been poor for this population, with no standard treatment. PATIENTS AND METHODS We retrospectively analyzed 72 Ven-naïve patients who received hypomethylating agents + venetoclax at relapse following alloHCT and aimed to evaluate the rates of complete remission with or without hematologic recovery (CR/CRi) and minimal residual disease (MRD) negativity, CR/CRi duration, and overall survival. We leveraged our larger sample to analyze the impact of cytogenetic/molecular features on the odds of CR/CRi. RESULTS CR/CRi was achieved among 32 of 67 (48%) patients, and MRD negativity was recorded among 10 of 12. NPM1 and IDH 1 or 2 mutations increased the odds of CR/CRi, as did increasing time from alloHCT to relapse. Fourteen patients subsequently received donor lymphocyte infusions or a second alloHCT. Responses lasted a median of 17.8 months (95% CI, 7.2 months to not reached), and responders had a greater median overall survival of 19.7 months (95% CI, 7.6-51.5 months) compared to 2.9 months among nonresponders (95% CI, 1.8-4.4 months; log-rank P < .01). Treatment was well tolerated, but prolonged cytopenias were common and most patients required reduction in the number of venetoclax days per cycle. CONCLUSION These data support the efficacy of this combination in the alloHCT relapse setting where we report responses among nearly half of patients, with possibly greater benefit for NPM1 and IDH 1/2-mutated cases. These responses can be durable and profound as evidenced by conversion to MRD negativity.

Complex karyotype but not other cytogenetic abnormalities is associated with worse posttransplant survival of patients with nucleophosmin 1-mutated acute myeloid leukemia: A study from the European Society for Blood and Marrow Transplantation Acute Leukemia Working Party. Am J Hematol 2024; 99:360-369.

Abstract
In the 2022 European LeukemiaNet classification, patients with nucleophosmin 1 (NPM1)-mutated acute myeloid leukemia (AML) were classified in the adverse-risk category in the presence of high-risk cytogenetics (CG). Nonetheless, the impact of various CG aberrations on posttransplant outcomes remains to be unraveled. This registry study analyzed adult patients with NPM1-mutated de novo AML who underwent their first allogeneic hematopoietic cell transplantation in the first complete remission from 2005 to 2021. A total of 3275 patients were identified, 2782 had normal karyotype, 493 had chromosomal aberrations including 160 with adverse-risk CG, 72 patients had complex karyotype (CK), and 66 monosomal karyotype (MK). Overall, 2377 (73%) patients had FLT3-ITD. On univariate analysis, only FLT3-ITD, minimal/measurable residual disease (MRD) positivity and CK, but not abnormal CG, affected posttransplant outcomes. On multivariable analysis, CK was associated with lower overall survival (OS) (hazard ratio [HR] 1.72, p = .009). In the subgroup of 493 patients with aberrant CG, the 2-year leukemia-free survival (LFS) and OS were around 61% and 68%, respectively. On multivariable analysis for this subgroup, CK and MRD positivity were associated with increased risk of relapse (HR 1.7, p = .025; and 1.99, p = .003 respectively) and worse LFS (HR 1.62, p = .018; and 1.64, p = .011 respectively) while FLT3-ITD, MK, or other CG abnormalities had no significant effect. Importantly, CK negatively affected OS (HR 1.91, p = .002). In the first complete remission transplant setting, CK was found as the only cytogenetic risk factor for worse outcomes in NPM1-mutated AML. Nevertheless, even for this subgroup, a significant proportion of patients can achieve long-term posttransplant survival.

Abstract
Allogeneic haematopoietic stem cell transplantation (HSCT) remains the only potential cure for intermediate to high-risk acute myeloid leukaemia (AML). The therapeutic effect of HSCT is largely dependent on the powerful donor-derived immune response against recipient leukaemia cells, known as graft-versus-leukaemia effect (GvL). However, the donor-derived immune system can also cause acute or chronic damage to normal recipient organs and tissues, in a process known as graft-versus-host disease (GvHD). GvHD is a leading cause of non-relapse mortality in HSCT recipients. There are many similarities and cross talk between the immune pathways of GvL and GvHD. Studies have demonstrated that both processes require the presence of mismatched alloantigens between the donor and recipient, and activation of immune responses centered around donor T-cells, which can be further modulated by various recipient or donor factors. Dissecting GvL from GvHD to achieve more effective GvHD prevention and enhanced GvL has been the holy grail of HSCT research. In this review, we focused on the key factors that contribute to the immune responses of GvL and GvHD, the effect on GvL with different GvHD prophylactic strategies, and the potential impact of various AML relapse prevention therapy or treatments on GvHD.
