New Developments in the Rapidly Evolving Landscape of Hepatitis C Therapy
丙型肝炎是当今美国最可怕的疾病之一,影响了大约2%的人口。它仍然是美国肝移植的最常见原因。每年有10,000-20,000名丙型肝炎患者死亡。标准干扰素/利巴韦林方案给出了六到十二个月,仅产生40-50%的治愈率。此外,患者面临副作用的高风险,包括但不限于甲状腺异常,视网膜病变,胰腺炎和血细胞性疾病。
幸运的是,在过去的两年中,这张临床图片已经明显了。美国和世界各地的领导肝病学家,包括118金宝搏抽水宾夕法尼亚州健康米尔顿·S·赫尔希医疗中心,帮助在丙型肝炎开创一个新时代treatment. Based on Phase III trials for which Milton S. Hershey Medical Center served as an investigational site, the protease inhibitors boceprevir and telaprevir were approved in 2011.伊恩·施雷布曼(Ian Schreibman),医学博士, associate professor of medicine,胃肠病学系医学院指出,“与干扰素不同,Boceprevir和Telaprevir直接破坏了病毒复制周期。当与干扰素和利巴韦林结合使用时,使用仅一半的一半(大约六个月)的治疗率较高的治疗率约为70%。这代表了丙型肝炎治疗的真正范式转移。”

Schreibman说:“在引入Boceprevir和Telaprevir的两年后,我们正处于另一种范式转变的风口浪尖。”制药公司已经开发了直接作用的抗病毒(DAAS),该抗病毒病病毒复制途径的不同步骤攻击各种蛋白质,这是一种类似于HIV的高度活性抗逆转录病毒疗法(HAART)的策略。这些药物可以在没有干扰素的情况下服用。“在过去的十二个月中,五个不同的II期和III期试验已经测试了丙型肝炎患者的新DAA,无干扰素治疗疗法仅持续了三到六个月,已经看到了90%以上的治疗率;一项试验报告的治愈率为100%,” Schreibman指出。到目前为止,副作用似乎在很大程度上是良性的,包括头痛,轻度胃肠道遇险和疲劳。
Schreibman is currently in discussions about potential involvement in upcoming phase II and III trials of several DAAs for hepatitis C. In May and June, he spoke at the Pennsylvania Department of Drug and Alcohol Program Hepatitis C Project Meeting and Milton S. Hershey Medical Center’s Sixth Annual Gastroenterology and Hepatology Spring Update to raise awareness among physicians about the challenges posed by these new, game-changing therapies. Schreibman notes, “There are risks, challenges, and difficult treatment choices posed with introduction of any new drug. Post-marketing safety and efficacy have not been determined. How does one select patients for new vs. old therapies? Should therapy be delayed in anticipation of new drug approval? Without adherence to proven treatment protocols, new, treatment-resistant hepatitis C strains may arise.” Physicians may be eager to embrace exciting more effective therapies but must do so with eyes wide open.
