Early Cardiac Toxicity Associated With Post-Transplant Cyclophosphamide in Allogeneic Stem Cell Transplantation.

ABSTRACT:

Background

Post-transplant cyclophosphamide (PT-Cy) has become a standard of care in haploidentical hematopoietic stem cell transplantation (HSCT) to reduce the risk of graft-versus-host disease. However, data on cardiac events associated with PT-Cy are scarce.

Objectives

This study sought to assess the incidence and clinical features of cardiac events associated with PT-Cy.

Methods

The study compared clinical outcomes between patients who received PT-Cy (n = 136) and patients who did not (n = 195), with a focus on early cardiac events (ECE) occurring within the first 100 days after HSCT. All patients had the same systematic cardiac monitoring.

Results

The cumulative incidence of ECE was 19% in the PT-Cy group and 6% in the no-PT-Cy group (p < 0.001). The main ECE occurring after PT-Cy were left ventricular systolic dysfunction (13%), acute pulmonary edema (7%), pericarditis (4%), arrhythmia (3%), and acute coronary syndrome (2%). Cardiovascular risk factors were not associated with ECE. In multivariable analysis, the use of PT-Cy was associated with ECE (hazard ratio: 2.7; 95% confidence interval: 1.4 to 4.9; p = 0.002]. Older age, sequential conditioning regimen, and Cy exposure before HSCT were also associated with a higher incidence of ECE. Finally, a history of cardiac events before HSCT and ECE had a detrimental impact on overall survival.

Conclusions

PT-Cy is associated with a higher incidence of ECE occurring within the first 100 days after HSCT. Patients who have a cardiac event after HSCT have lower overall survival. These results may help to improve the selection of patients who are eligible to undergo HSCT with PT-Cy, especially older adult patients and patients with previous exposure to Cy.

Project description:BackgroundAllogeneic blood or marrow transplantation (alloBMT) is a potentially life-saving treatment for individuals with HIV and haematological malignancies; challenges include identifying donors and maintaining antiretroviral therapy (ART). The objectives of our study were to investigate interventions to expand donor options and to prevent ART interruptions for patients with HIV in need of alloBMT.MethodsThis single-arm, interventional trial took place at the Johns Hopkins Sidney Kimmel Comprehensive Cancer Center (Baltimore, MD, USA). Individuals with HIV who were at least 18 years of age and referred for alloBMT for a standard clinical indication were eligible. The only exclusion criterion was a history of documented resistance to enfuvirtide. We used post-transplant cyclophosphamide as graft-versus-host disease (GVHD) prophylaxis to expand donor options and an optimised ART strategy of avoiding pharmacoenhancers and adding subcutaneous enfuvirtide during post-transplant cyclophosphamide and during oral medication intolerance. Our primary outcome was the proportion of participants who maintained ART through day 60 after alloBMT. We measured the HIV latent reservoir using a quantitative viral outgrowth assay. This study is registered on ClinicalTrials.gov, NCT01836068.FindingsBetween June 1, 2013, and August 27, 2015, nine patients who were referred for transplant provided consent. Two patients had relapsed malignancy before donor searches were initiated. Seven patients had suitable donors identified (two matched sibling, two matched unrelated, two haploidentical, and one single-antigen mismatched unrelated) and proceeded to alloBMT. All patients maintained ART through day 60 and required ART changes (median 1, range 1-3) in the first 90 days. One patient stopped ART and developed HIV rebound with grade 4 meningoencephalitis at day 146. Among six patients who underwent alloBMT and had longitudinal measurements available, the HIV latent reservoir was not detected post-alloBMT in four patients with more than 95% donor chimerism, consistent with a 2·06-2·54 log10 reduction in the HIV latent reservoir. In the two patients with less than 95% donor chimerism, the HIV latent reservoir remained stable.InterpretationBy using post-transplant cyclophosphamide as GVHD prophylaxis, we successfully expanded alloBMT donor options for patients with HIV. Continuing ART with a regimen that includes enfuvirtide post-alloBMT was safe, but life-threatening viral rebound can occur with ART interruption.FundingamfAR (the Foundation for AIDS Research), Johns Hopkins University Center for AIDS Research, and National Cancer Institute.

Project description:BackgroundPost-transplant cyclophosphamide (PTCy) and anti-thymocyte globulin (ATG) are both common graft-versus-host disease (GVHD) prophylaxis strategies in allo-HSCT from unrelated donors. However, no consensus has reached on which regimen is optimal. Although several studies concerning this topic exist, the outcomes of different studies still conflict with each other. Therefore, an overall comparison of the two regimens is urgently needed to help make informed clinical decisions.MethodsStudies comparing PTCy and ATG regimens in unrelated donor (UD) allo-HSCT were searched in four critical medical databases from inception to April 17, 2022. The primary outcome was grade II-IV aGVHD, grade III-IV aGVHD and chronic GVHD (cGVHD), and the secondary outcomes included overall survival (OS), relapse incidence (RI), non-relapse mortality (NRM), and several severe infectious complications. The quality of articles was assessed by the Newcastle-Ottawa scale (NOS), and data were extracted by two independent investigators and then analyzed by RevMan 5.4.ResultsSix out of 1091 articles were eligible for this meta-analysis. Compared with the ATG regimen, prophylaxis based on PTCy achieved a lower incidence of grade II-IV aGVHD incidence (RR=0.68, 95% CI 0.50-0.93, P=0.010, I 2 = 67%), grade III-IV aGVHD (RR=0.32, 95% CI 0.14-0.76, P=0.001, I 2 = 75%), NRM (RR=0.67, 95% CI 0.53-0.84, P=0.17, I 2 = 36%), EBV-related PTLD (RR=0.23, 95% CI 0.09-0.58, P=0.85, I 2 = 0%) and better OS (RR=1.29, 95% CI 1.03-1.62, P=0.0001, I 2 = 80%). The cGVHD, RI, CMV reactivation and BKV-related HC showed no significant difference between the two groups (RR=0.66, 95% CI 0.35-1.26, P<0.00001, I 2 = 86%; RR=0.95, 95% CI 0.78-1.16, P=0.37, I 2 = 7%; RR=0.89, 95% CI 0.63-1.24, P=0.07, I 2 = 57%; RR=0.88, 95% CI 0.76-1.03, P=0.44, I 2 = 0%).ConclusionIn the setting of unrelated donor allo-HSCT, prophylaxis based on PTCy can lower the incidence of grade II-IV aGVHD, grade III-IV aGVHD, NRM and EBV-related complication, achieve better OS compared to ATG-based regimen. And cGVHD, RI, CMV reactivation and BKV-related HC were comparable in the two groups.

Project description:BackgroundAllogeneic hematopoietic cell transplantation (allo-HCT) using a mismatched unrelated donor (MMUD) and cord blood transplantation (CBT) are valid alternatives for patients without a fully human leukocyte antigen (HLA)-matched donor. Here, we compared the allo-HCT outcomes of CBT versus single-allele-mismatched MMUD allo-HCT with post-transplant cyclophosphamide (PTCy) in acute myeloid leukemia.MethodsPatients who underwent a first CBT without PTCy (N = 902) or allo-HCT from a (HLA 9/10) MMUD with PTCy (N = 280) were included in the study. A multivariate regression analysis was performed for the whole population. A matched-pair analysis was carried out by propensity score-based 1:1 matching of patients (177 pairs) with known cytogenetic risk.ResultsThe incidence of grade II-IV and grade III-IV acute graft-versus-host disease (GVHD) at 6 months was 36% versus 32% (p = 0.07) and 15% versus 11% (p = 0.16) for CBT and MMUD cohorts, respectively. CBT was associated with a higher incidence of graft failure (11% vs. 4%, p < 0.01) and higher 2-year non-relapse mortality (NRM) (30% vs. 16%, p < 0.01) compared to MMUD. In the multivariate analysis, CBT was associated with a higher risk of, NRM (HR = 2.09, 95% CI 1.46-2.99, p < 0.0001), and relapse (HR = 1.35, 95% CI 1-1.83, p = 0.05), which resulted in worse leukemia-free survival (LFS) (HR = 1.68, 95% CI 1.34-2.12, p < 0.0001), overall survival (OS) (HR = 1.7, 95% CI 1.33-2.17, p < 0.0001), and GVHD-free, relapse-free survival (GRFS) (HR = 1.49, 95% CI 1.21-1.83, p < 0.0001) compared to MMUD. The risk of grade II-IV acute GVHD (p = 0.052) and chronic GVHD (p = 0.69) did not differ significantly between the cohorts. These results were confirmed in a matched-pair analysis.ConclusionsCBT was associated with lower LFS, OS, and GRFS due to higher NRM, compared to MMUD allo-HCT with PTCy. In the absence of a fully matched donor, 9/10 MMUD with PTCy may be preferred over CBT.
