Regulatory agencies must balance patient demands to access new treatments for fatal diseases with limited treatment options while ensuring drug safety and efficacy. However, questionable U.S. regulatory actions resulted in the early approval of AMX0035 to treat amyotrophic lateral sclerosis (ALS) by reconvening advisory commissions to obtain positive decisions and designating the drug as a new molecular entity. Data from one randomized clinical trial suggests minimal delays in disease progression and longer survivability, but debate remains about the lack of confirmatory evidence of effectiveness owing to study limitations. A patient's decision-making process details the experience of using the drug, including perspectives on access, cost, effectiveness, and adverse effects. In line with the "nichebuster" business model, the drugmaker, Amylyx Pharmaceuticals, is charging US$158,000/year/patient and thus forecast to turn a profit on a drug with debatable clinical effectiveness prior to completing a Phase 3 trial. Early marketing approval, despite community demands, is unnecessary and may have reduced access because of the end of a compassionate use program, and the high price tag results in restricted coverage and high out-of-pocket costs. Also, the drug's key ingredients are available as a generic and a supplement.
监管机构必须在确保药物安全性和有效性的同时,平衡患者对治疗致命疾病的新疗法的需求与有限的治疗选择。然而,美国有争议的监管行动导致 AMX0035 被提前批准用于治疗肌萎缩侧索硬化症(ALS),其方法是重新召集顾问委员会以获得积极的决定,并将该药物指定为一种新的分子实体。一项随机临床试验的数据表明,疾病进展的延迟最小化,并且存活时间更长,但由于研究的局限性,仍然存在关于缺乏有效性的确认证据的争议。患者的决策过程详细说明了使用该药物的体验,包括对获取途径、成本、有效性和不良反应的看法。与“利基破坏者”商业模式一致,制药商 Amylyx Pharmaceuticals 对该药物收取 15.8 万美元/年/患者的费用,因此,在完成 3 期试验之前,该药物在具有争议的临床疗效方面可能会盈利。尽管社区有需求,但提前营销批准是不必要的,并且可能由于同情使用计划的结束而减少了获得途径,而高价导致覆盖范围受限和自付费用高。此外,该药物的关键成分可作为仿制药和补充剂使用。
