2011年3月29日,美国食品和药品监督管理局批准聚乙二醇干扰素α-2b [聚乙二醇干扰素α-2b](Sylatron, 先灵公司Schering Corporation, Kenilworth, NJ 07033),为治疗最终手术切除包括完整的淋巴结清扫术84天内有显微镜或大体肉眼累及淋巴结黑色素瘤患者。 批准是根据单项试验,EORTC 18991,一项开放,多中心试验纳入1256例患者。原发皮肤黑色素瘤和受影响的区域淋巴结已被适当地切除患者被随机化(1:1)至接受或 Sylatron或观察为期5年。分层因素包括累及淋巴结类型(显微镜相比大体肉眼),阳性淋巴结数(1,2-4,5或更多,或未评估),Breslow 原发厚度(小于1.5 mm,≥ 1.5至4 mm,≥ 4 mm),原发肿瘤的溃疡(存在或缺乏或未知),性别,和研究中心。对治疗的头两年每三个月和随后每6个月直至试验结束,评估患者局部和区域复发或远处转移。一个独立审评委员会,对随机化赋予盲态和告知将破坏治疗的盲态,审评来自数据的病例报告以确定局部-区域复发,或远处转移的发生和日期。 主要疗效终点,无复发生存(RFS),被定义为至最早局部或区域复发,远处转移,或死亡的时间。根据696次RFS事件,对Sylatron-治疗患者 RFS改善[风险比0.82(95% CI:0.71,0.96);观察到不分层log-rank p = 0.011]。 在SYLATRON和观察组中估算的中位RFS分别为34.8个月(95% CI:26.1, 47.4)和25.5个月(95% CI:19.6,30.8)。 对研究后525例死亡,Sylatron和观察组间总生存无差别[风险比0.98(95% CI:0.82,1.16)]。 在EORTC 18991中评价608例Sylatron-治疗患者的安全性。Sylatron-治疗患者经受最常见(>60%)1-4级不良反应是疲乏,ALT 增高,AST增高,发热,头痛,厌食,肌肉痛,恶心,畏寒,和注射部位反应。发生在Sylatron-治疗患者中最常见严重不良反应是疲乏,ALT增高,AST增高,和发热。 接受Sylatron患者中33%由于不良反应终止治疗。治疗终止时存在的最常见不良反应是疲乏,抑郁,厌食,ALT增高,AST增高,肌肉痛,恶心,头痛,和发热。Sylatron末次给药的30天内报道5例死亡。2例归咎于复发疾病,两例归咎于心血管疾病可能与Sylatron有关,和一例归咎于意外。 对Sylatron推荐的剂量和方案是6 μg/kg/周,皮下共 8剂,接着皮下3 μg/kg/周。最长治疗期是5年(260周)。
SYLATRON
Manufacturer:
Merck & Co., Inc.
Pharmacological Class:
Alpha interferon
Active Ingredient(s):
Peginterferon alfa-2b 296mcg, 444mcg, 888mcg; per vial; pwd for SC inj after reconstitution.
Indication(s):
Adjuvant treatment of melanoma with microscopic or gross nodal involvement within 84 days of definitive surgical resection including complete lymphadenectomy.
Pharmacology:
Peginterferon alfa-2b is a pleiotropic cytokine; the mechanism by which it exerts its effects in patients with melanoma is unknown.
Clinical Trials:
The safety and efficacy of Sylatron were evaluated in an open-label, multicenter, randomized study conducted in 1,256 patients with surgically resected, AJCC Stage III melanoma within 84 days of regional lymph node dissection. Patients were randomized to observation (no therapy) (n=629) or to Sylatron (n=627) at a dose of 6mcg/kg by SC injection once weekly for 8 doses followed by a 3mcg/kg SC injection once weekly for a period of up to 5 years total treatment. The dose of Sylatron was adjusted to maintain an ECOG Performance Status of 0 to 1. The main outcome measure was relapse-free survival (RFS), defined as the time from randomization to the earliest date of any relapse (local, regional, in-transit, or distant), or death from any cause. Secondary outcome measures included overall survival.
Based on 696 RFS events, determined by the Independent Review Committee, median RFS was 34.8 months and 25.5 months in the Sylatron and observation arms, respectively. There was no statistically significant difference in survival between the Sylatron and the observation arms.
