For patients with cancer who have exhausted approved treatment options and for whom appropriate clinical trials are not available, access to investigational drugs through the US Food and Drug Administration's Expanded Access (EA) program has been an alternative since the program's inception more than 30 years ago. In 2018, federal Right To Try legislation was passed in the United States, creating a second pathway-one that bypasses the US Food and Drug Administration-to obtain unapproved drugs outside of clinical trials. The use of the two programs by community medical oncologists and hematologist-oncologists has not been studied.
Between October 2019 and February 2020, community oncologists-hematologists from across the United States completed web-based surveys about EA and Right To Try pathways for accessing unapproved drugs for their patients. Physicians were asked about their utilization of, and perceptions of, the two programs.
Of the 238 physicians who completed the survey, 46% indicated that they had attempted to gain access to an investigational drug for a patient using the EA program, whereas 14% reported attempting to use Right To Try pathway to obtain an unapproved drug for a patient. Eighty-nine percent of those who tried to use the EA program reported success in obtaining the investigational drug versus 73% of those who attempted to use the Right To Try pathway.
Our survey found that most community oncologists-hematologists were aware of both the EA and Right To Try pathways, but there is room for improvement in understanding and utilization of the programs.
对于已用尽批准治疗方案且无合适临床试验可供选择的癌症患者,自 30 多年前该项目启动以来,通过美国食品和药物管理局(FDA)扩大准入(Expanded Access,EA)计划获得试验性药物是一种替代方案。2018 年,美国通过了联邦“尝试权”立法,创建了第二条途径——绕过 FDA,在临床试验之外获得未经批准的药物。目前尚未研究社区肿瘤学家和血液科肿瘤学家对这两个项目的使用情况。
2019 年 10 月至 2020 年 2 月,来自美国各地的社区肿瘤学家-血液科医生通过网络调查,了解他们在为患者使用 EA 和“尝试权”途径获取未经批准药物方面的情况。医生们被问及他们对这两个项目的使用情况和看法。
在完成调查的 238 名医生中,46%的人表示他们曾试图通过 EA 项目为患者获得试验性药物,而 14%的人表示曾试图通过“尝试权”途径获得未经批准的药物。89%试图使用 EA 项目的人报告成功获得了研究药物,而试图使用“尝试权”途径的人中有 73%报告成功。
我们的调查发现,大多数社区肿瘤学家-血液科医生都了解 EA 和“尝试权”途径,但在理解和使用这些途径方面仍有改进的空间。
