Clofarabine and total body irradiation (TBI) as conditioning regimen for allogeneic stem cell transplantation in high-risk acute leukemia patients: a two-center retrospective cohort study. Bone Marrow Transplant 2023:10.1038/s41409-023-01947-z. [PMID: 36914730 DOI: 10.1038/s41409-023-01947-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 02/14/2023] [Accepted: 02/20/2023] [Indexed: 03/16/2023]
Abstract
Clofarabine (Clo) is an immunosuppressive purine analog that may have better anti-leukemic activity than fludarabine (Flu). The addition of total body irradiation (TBI) to conditioning regimens has been widely investigated. However, the use of single agent Clo in combination with intermediate doses of TBI ranging from 4 to 8 Gy has not been studied yet. This study is a double center, observational, retrospective study of patients with high-risk hematological malignancies diagnosed from 2012 to 2021, treated at the American University of Beirut Medical Center in Beirut (AUBMC), Lebanon, and Saint-Antoine Hospital (SAH) in Paris, France. It aims to identify the outcome of patients with high-risk hematological malignancies who underwent allogeneic stem cell transplant (allo-SCT) and received Clo and TBI (4-8 Gy) before transplant. Data regarding patient baseline characteristics, disease-related factors, and transplant outcomes including graft-versus-host disease (GVHD), Non-relapse mortality (NRM), progression-free survival (PFS), and overall survival (OS), were collected. We identified 24 high-risk patients diagnosed with a hematological malignancy. The median age at transplant was 37 years (range 22-78). At the time of the transplant, only 15 patients (63%) were in complete remission (CR). All patients received Clo/TBI (4-8 Gy). After a median follow-up of 40 months, the cumulative incidences of grade II-III acute GVHD, grade IV acute GVHD, and chronic GVHD were 50%, 4%, and 8%, respectively. NRM at 100 days, and 1 year after transplant was 4% and 25%, respectively. 17% of the patients had a relapse or progression of the disease by the end of the study. The 2-year PFS and OS were 50% and 56%, respectively. The median PFS and OS were 66 and 68 months respectively. As a conclusion, Clo/TBI (4-8 Gy) as a conditioning regimen for allo-SCT in high-risk patients confers disease control with an acceptable toxicity profile.

Abstract
Monitoring for liver injury remains an important aspect of drug safety assessment, including for oncotherapeutics. When present, drug-induced liver injury may limit the use or result in the discontinuation of these agents. Drug-induced liver injury can exhibit with a wide spectrum of clinical and biochemical manifestations, ranging from transient asymptomatic elevations in aminotransferases (TAEAT) to acute liver failure. Numerous oncotherapeutics have been associated with TAEAT, with published reports indicating a phenomenon in which patients may be asymptomatic without overt liver injury despite the presence of grade ≥3 aminotransferase elevations. In this review, we discuss the occurrence of TAEAT in the context of oncology clinical trials and clinical practice, as well as the clinical relevance of this phenomenon as an adverse event in response to oncotherapeutics and the related cellular and molecular mechanisms that may underlie its occurrence. We also identify several gaps in knowledge relevant to the diagnosis and the management of TAEAT in patients receiving oncotherapeutics, and identify areas warranting further study to enable the future development of consensus guidelines to support clinical decision-making.

Abstract
Clofarabine is an immunosuppressive purine nucleoside analog that may have better anti-leukemic activity than fludarabine. We performed a prospective phase I/II multisite trial of clofarabine with 2 Gy total body irradiation as non-myeloablative conditioning for allogeneic hematopoietic cell transplantation in adults with acute myeloid leukemia who were unfit for more intense regimens. Our main objective was to improve the 6-month relapse rate following non-myeloablative conditioning, while maintaining historic rates of non-relapse mortality (NRM) and engraftment. Forty-four patients, 53 to 74 (median: 69) years, were treated with clofarabine at 150 to 250 mg/m2 , of whom 36 were treated at the maximum protocol-specified dose. One patient developed multifactorial acute kidney injury and another developed multiorgan failure, but no other grade 3 to 5 non-hematologic toxicities were observed. All patients fully engrafted. The 6-month relapse rate was 16% (95% CI, 5%-27%) among all patients and 14% (95% CI, 3%-26%) among high-risk patients treated at the maximum dose, meeting the pre-specified primary efficacy endpoint. Overall survival was 55% (95% CI, 40%-70%) and leukemia-free survival was 52% (95% CI, 37%-67%) at 2 years. Compared to a historical high-risk cohort treated with the combination of fludarabine at 90 mg/m2 and 2 Gy TBI, protocol patients treated with the clofarabine-TBI regimen had lower rates of overall mortality (HR of 0.50, 95% CI, 0.28-0.91), disease progression or death (HR 0.48, 95% CI, 0.27-0.85), and morphologic relapse (HR 0.30, 95% CI, 0.13-0.69), and comparable NRM (HR 0.85, 95% CI 0.36-2.00). The combination of clofarabine with TBI warrants further investigation in patients with high-risk AML.

Gamma-Tocotrienol Protects the Intestine from Radiation Potentially by Accelerating Mesenchymal Immune Cell Recovery. Antioxidants (Basel) 2019; 8:antiox8030057. [PMID: 30845647 PMCID: PMC6466604 DOI: 10.3390/antiox8030057] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 02/24/2019] [Accepted: 02/28/2019] [Indexed: 12/12/2022] Open
Abstract
Natural antioxidant gamma-tocotrienol (GT3), a vitamin E family member, provides intestinal radiation protection. We seek to understand whether this protection is mediated via mucosal epithelial stem cells or sub-mucosal mesenchymal immune cells. Vehicle- or GT3-treated male CD2F1 mice were exposed to total body irradiation (TBI). Cell death was determined by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Villus height and crypt depth were measured with computer-assisted software in tissue sections. Functional activity was determined with an intestinal permeability assay. Immune cell recovery was measured with immunohistochemistry and Western blot, and the regeneration of intestinal crypts was assessed with ex vivo organoid culture. A single dose of GT3 (200 mg/kg body weight (bwt)) administered 24 h before TBI suppressed cell death, prevented a decrease in villus height, increased crypt depth, attenuated intestinal permeability, and upregulated occludin level in the intestine compared to the vehicle treated group. GT3 accelerated mesenchymal immune cell recovery after irradiation, but it did not promote ex vivo organoid formation and failed to enhance the expression of stem cell markers. Finally, GT3 significantly upregulated protein kinase B or AKT phosphorylation after TBI. Pretreatment with GT3 attenuates TBI-induced structural and functional damage to the intestine, potentially by facilitating intestinal immune cell recovery. Thus, GT3 could be used as an intestinal radioprotector.

Abstract
Acute leukemias in children with CR3, refractory relapse, or induction failure (IF) have a poor prognosis. Clofarabine has single agent activity in relapsed leukemia and synergy with cytarabine. We sought to determine the safety and overall survival in a Phase I/II trial of conditioning with clofarabine (doses 40 - 52 mg/m2), cytarabine 1000 mg/m2, and 1200 cGy TBI followed by alloSCT in children, adolescents, and young adults with poor-risk leukemia. Thirty-seven patients; Age 12 years (1-22 years); ALL/AML: 34:3 (18 IF, 10 CR3, 13 refractory relapse); 15 related, 22 unrelated donors. Probabilities of neutrophil, platelet engraftment, acute GvHD, and chronic GvHD were 94%, 84%, 49%, and 30%, respectively. Probability of day 100 TRM was 8.1%. 2-year EFS (event free survival) and OS (overall survival) were 38.6% (CI95: 23-54%), and 41.3% (CI95: 25-57%). Multivariate analysis demonstrated overt disease at time of transplant (relative risk (RR) 3.65, CI95: 1.35-9.89, P = 0.011) and umbilical cord blood source (RR 2.17, CI95: 1.33-4.15, P = 0.019) to be predictors of worse EFS/OS. This novel myeloablative conditioning regimen followed by alloSCT is safe and well tolerated in CAYA with very poor-risk ALL or AML. Further investigation in CAYA with better risk ALL and AML undergoing alloSCT is warranted.

Abstract
Despite great success in the development of curative therapies for pediatric hematologic malignancies, new approaches are needed to overcome resistance to treatment and to reduce associated side effects. The Therapeutic Advances in Childhood Leukemia and Lymphoma (TACL) Consortium is an early phase clinical trial group dedicated to developing innovative therapies for currently incurable pediatric leukemias and lymphomas ( https://tacl.chla.usc.edu/tacl/ ). In November of 2016, a TACL Investigator Meeting was held, the proceedings of which appear in this edition of Pediatric Hematology Oncology. This introductory article provides an overview of TACL and introduces the five-part proceedings.
