Abstract
PURPOSE This trial evaluated whether the addition of sitagliptin to antithymocyte globulin (ATG)–based prophylaxis reduces the incidence of acute graft-versus-host disease (aGVHD) after alternative donor hematopoietic stem-cell transplantation. METHODS This prospective, multicenter, open-label, randomized trial enrolled patients age 18-60 years with hematologic malignancies who received myeloablative conditioning haploidentical or unrelated donor transplantation. Participants were randomly assigned in a 1:1 ratio to ATG-based prophylaxis (ATG + calcineurin inhibitor + methotrexate + mycophenolate mofetil) with or without sitagliptin (600 mg orally once every 12 hours, days –1 to +14). The primary end point was the cumulative incidence of grade Ⅱ-Ⅳ aGVHD by day +100. RESULTS From December 22, 2021, to June 16, 2023, 190 of the 251 screened patients were enrolled, with a median follow-up of 29.8 (0.7-41.3) months. The sitagliptin group had a significantly lower incidence of grade Ⅱ-Ⅳ aGVHD on day +100 (14.7% v 31.6%; subdistribution hazard ratio [sHR] = 0.41; P = .005). Reduced grade Ⅲ-Ⅳ (6.3% v 18.9%; sHR = 0.30; P = .010) and intestinal aGVHD (12.6% v 29.5%; P = .004) and superior day +180 GVHD-free, relapse-free survival (GRFS; 86.3% v 72.6%; HR = 0.44; P = .016) were also observed. No between-group disparities were detected in 2-year chronic GVHD, nonrelapse mortality, relapse-free/overall survival, or cytomegalovirus/Epstein-Barr virus reactivation; the adverse event profiles were similar. CONCLUSION In this randomized trial, adjunct sitagliptin to ATG-containing prophylaxis significantly reduced the incidence of grade Ⅱ-Ⅳ aGVHD. Reductions in severe and intestinal aGVHD, as well as improved day +180 GRFS, were exploratory observations; no significant benefits were detected for long-term GRFS, overall survival, or RFS, and treatment did not alter the engraftment, relapse, or infection risk.
目的:本试验评估西格列汀加入抗胸腺细胞球蛋白(ATG)预防是否能降低替代供体造血干细胞移植后急性移植物抗宿主病(aGVHD)的发生率。方法:这项前瞻性、多中心、开放标签、随机试验纳入了年龄在18-60岁的恶性血液病患者,这些患者接受了清髓调节单倍体或非亲属供体移植。参与者以1:1的比例随机分配到以ATG为基础的预防(ATG +钙调磷酸酶抑制剂+甲氨蝶呤+霉酚酸酯),有或没有西格列汀(600毫克,每12小时口服一次,第1天至第14天)。主要终点是第100天Ⅱ-Ⅳ级aGVHD的累积发病率。结果从2021年12月22日至2023年6月16日,251例筛查患者中有190例入组,中位随访时间为29.8(0.7-41.3)个月。西格列汀组在第100天Ⅱ-Ⅳ级aGVHD发生率显著降低(14.7% vs 31.6%;亚分布风险比[sHR] = 0.41; P = 0.005)。患者的分级降低Ⅲ-Ⅳ(6.3% v 18.9%; sHR = 0.30; P = 0.010),肠道aGVHD (12.6% v 29.5%; P = 0.004),无gvhd、无复发生存(GRFS; 86.3% v 72.6%; HR = 0.44; P = 0.016)。在2年慢性GVHD、非复发死亡率、无复发/总生存率或巨细胞病毒/ eb病毒再激活方面,组间未发现差异;不良事件概况相似。结论:在这项随机试验中,西格列汀辅助含atg预防可显著降低Ⅱ-Ⅳ级aGVHD的发生率。严重和肠道aGVHD的减少,以及day +180 GRFS的改善是探索性观察;在长期GRFS、总生存期或RFS方面没有发现明显的益处,治疗也没有改变植入、复发或感染的风险。
