背景:Ramucirumab用于晚期肝细胞癌(HCC)和甲胎蛋白(AFP)≥400ng/mL的索拉非尼治疗。这里,我们前瞻性研究了非索拉非尼系统治疗后的雷莫西单抗.
方法:这个开放标签,REACH-2纳入晚期HCC患者的非比较队列,Child-PughA级肝病,AFP≥400ng/mL,接受1-2行治疗,不包括索拉非尼或化疗。Ramucirumab静脉内施用8mg/kgQ2W。主要终点是安全性。次要终点是总生存期,无进展生存期,客观反应率(RECISTV1.1),进步的时间,药代动力学,和患者报告的结果。最终分析发生在所有入选患者完成≥3个治疗周期或停止治疗后。
结果:在2018年4月27日至2021年3月29日之间,亚洲21个调查地点的47名患者接受了治疗。欧洲,和美国。最常报告的≥3级不良事件,不管因果关系,高血压(11%),蛋白尿(6%),低钠血症(6%),AST增加(6%)。2例患者死于不良事件(心肌梗死和上消化道出血),认为与治疗有关。中位无进展生存期,进步的时间,总生存期为1.7个月,2.8个月,8.7个月,分别。客观缓解率为10.6%,中位缓解时间为8.3个月。FHSI-8总分恶化的中位时间为4.4个月。
结论:Ramucirumab在晚期HCC和AFP≥400ng/mL患者非索拉非尼治疗后表现出一致且有意义的临床活性,没有新的安全性信号。这代表了未经索拉非尼治疗的晚期HCC患者的首批测序研究之一。
Ramucirumab is indicated for patients with advanced hepatocellular carcinoma (HCC) and α-fetoprotein (AFP) ≥400 ng/mL following sorafenib. Here, we prospectively studied ramucirumab following non-sorafenib systemic therapies.
This open-label, non-comparative cohort of REACH-2 enrolled patients with advanced HCC, Child-Pugh class-A liver disease, and AFP ≥400 ng/mL who had received 1-2 lines of therapy, excluding sorafenib or chemotherapy. Ramucirumab was administered 8 mg/kg intravenously Q2W. The primary endpoint was safety. Secondary endpoints were overall survival, progression-free survival, objective response rate (RECIST v1.1), time to progression, pharmacokinetics, and patient-reported outcomes. Final analysis occurred after all enrolled patients completed ≥3 treatment cycles or discontinued treatment.
Between April 27, 2018, and March 29, 2021, 47 patients were treated at 21 investigative sites in Asia, Europe, and USA. The most frequently reported grade ≥3 adverse events, regardless of causality, were hypertension (11%), proteinuria (6%), hyponatremia (6%), and AST increased (6%). Two patients died from adverse events (myocardial infarction and upper gastrointestinal hemorrhage), deemed related to treatment. Median progression-free survival, time to progression, and overall survival were 1.7 months, 2.8 months, and 8.7 months, respectively. The objective response rate was 10.6% with a median duration response of 8.3 months. Median time to deterioration in FHSI-8 total score was 4.4 months.
Ramucirumab demonstrated consistent and meaningful clinical activity with no new safety signals following non-sorafenib therapies in patients with advanced HCC and AFP ≥400 ng/mL. This represents one of the first sequencing studies for patients with advanced HCC not treated with sorafenib.
