Ruxolitinib and decitabine plus a busulfan-cyclophosphamide conditioning regimen for relapse prophylaxis in patients with high-risk acute myeloid leukemia or myelodysplastic syndromes.

Purpose: Relapse remains the leading cause of treatment failure in high-risk acute myeloid leukemia (AML) or myelodysplastic syndrome-IB (MDS-IB) patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Ruxolitinib has demonstrated antileukemic activity , and decitabine has been found to be tolerable when combined with modified busulfan-cyclophosphamide (mBu/Cy) conditioning regimen. Here, we investigated the efficacy of ruxolitinib and decitabine plus a mBu/Cy conditioning regimen (Rux-Dec-mBu/Cy) in reducing relapse in high-risk AML/MDS patients ().

[Efficacy and Safety of Decitabine-Based Myeloablative Preconditioning Regimen for allogeneic Hematopoietic Stem Cell Transplantation in Patients with Acute Myeloid Leukemia].

Objective: To analyze the efficacy and safety of decitabine-based myeloablative preconditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with acute myeloid leukemia (AML).

Methods: The clinical characteristics and efficacy of 115 AML patients who underwent allo-HSCT at the First Medical Center of Chinese PLA General Hospital from August 2018 to August 2022 were retrospectively analyzed, including 37 patients treated with decitabine conditioning regimen (decitabine group) and 78 patients without decitabine conditioning regimen (non-decitabine group). The cumulative incidence of relapse (CIR), overall survival (OS), leukemia-free survival (LFS), non-relapse mortality (NRM) and graft versus host disease (GVHD) were analyzed.

Ruxolitinib plus steroids for acute graft versus host disease: a multicenter, randomized, phase 3 trial.

Newly diagnosed patients with high-risk acute graft-versus-host disease (aGVHD) often experience poor clinical outcomes and low complete remission rates. Ruxolitinib with corticosteroids showed promising efficacy in improving response and failure free survival in our phase I study. This study (ClinicalTrials.

Addition of ruxolitinib and decitabine to modified busulfan/cyclophosphamide conditioning regimen for prophylaxis relapse in high-risk acute myeloid leukemia: the phase 2 prospective study.

The prognosis of patients with high-risk acute myeloid leukemia (AML) is dismal even after allogeneic stem cell transplantation (allo-HSCT), with relapse remaining the leading cause of treatment failure. Here, we investigated whether ruxolitinib and decitabine plus modified busulfan-cyclophosphamide (mBu/Cy) conditioning could reduce relapse in high-risk AML after allo-HSCT. This prospective, single-arm, phase II trial enrolled 37 patients who received allo-HSCT between September 2020 and March 2022 at the First Medical Center of Chinese People's Liberation Army (PLA) General Hospital.

Patients Beyond the Optimal Range of rATG-AUC Still Benefit from the Targeted Dosing Strategy in Unmanipulated Haplo-PBSCT.

Rabbit antithymocyte globulin (rATG) is widely used in allogeneic hematopoietic stem cell transplantation to prevent graft failure and severe graft-versus-host disease (GVHD). We developed a rATG-targeted dosing strategy based on the optimal areas under the concentration-time curve (AUC) of active rATG. This study compared the outcomes of the optimal AUC arm with nonoptimal AUC arm to assess the effect of the rATG-targeted dosing strategy.

Targeted dosing of anti-thymocyte globulin in adult unmanipulated haploidentical peripheral blood stem cell transplantation: A single-arm, phase 2 trial.

Anti-thymocyte globulin (ATG) is widely used in allogeneic hematopoietic stem cell transplantation to prevent severe graft-versus-host disease (GVHD) and graft failure. However, overexposure to ATG may increase cytomegalovirus (CMV), Epstein-Barr virus (EBV) reactivation, non-relapse mortality, and disease recurrence. To investigate the optimal dosing of ATG, we established a targeted dosing strategy based on ATG concentration monitoring for haploidentical peripheral blood stem cell transplantation (haplo-PBSCT).

[The Prognostic Value of FOSB Gene in Acute Myeloid Leukemia].

Unlabelled: AbstractObjective: To analyze the expression of FOSB in acute myeloid leukemia （AML） and its correlation with prognosis of the patient based on the large sample data.

Methods: The genome, transcriptome, gene chip and clinical information from multiple public databases were statistical analyzed.

Results: The expression of FOSB gene in AML patients was significantly higher than that in normal people.

Co-Administration with Voriconazole Doubles the Exposure of Ruxolitinib in Patients with Hematological Malignancies.

Background: Ruxolitinib is newly approved for glucocorticoid-refractory acute graft-versus-host disease (GVHD) in patients undergoing allo-geneic hematopoietic stem-cell transplantation (allo-HSCT), and voriconazole is commonly used in allo-HSCT recipients for the prophylaxis or treatment of invasive fungal infections (IFIs). Drug-drug interaction (DDI) may occur between them because their metabolic pathways overlap and can be inhibited by voriconazole, including cytochrome P450 (CYP) isozymes 3A4 and 2C9.

Objective: In the present study, we aimed to investigate the DDI between ruxolitinib and voriconazole in patients with hematological malignancies.
