Difficulties and challenges in the clinical trial of new drugs for nonalcoholic steatohepatitis
-
摘要: 近年来非酒精性脂肪性肝炎(NASH)的发病率不断增长,且临床上缺乏有效的治疗药物。从NASH的异质性(如体质量、性别、年龄和代谢因素)、混杂因素的影响、量化指标的诊断一致性等方面分析了NASH新药临床试验开发的难度,提出可以通过分层分析、减弱混杂因素影响、提高诊断一致性等方式提高NASH新药临床试验的质量。包括生活方式改善在内的联合治疗可能是有效的NASH治疗策略,以改善NASH和抗纤维化及长期代谢获益为目标的治疗是未来药物研发的研究方向。Abstract: The incidence rate of nonalcoholic steatohepatitis (NASH) keeps increasing in recent years, and there is still a lack of effective therapeutic drugs in clinical practice. This article analyzes the difficulties in the clinical trial of new drugs for NASH from the aspects of the heterogeneity of NASH (body weight, sex, age, and metabolic factors), the influence of confounding factors, and the diagnostic consistency of quantitative indicators, and it is pointed out that conducting a stratified analysis, reducing the influence of confounding factors, and improving diagnostic consistency can help to improve the quality of the clinical trials of new drugs for NASH. Combination therapy including lifestyle improvement may be an effective treatment strategy for NASH, and therapies aiming at improving NASH, exerting an anti-fibrosis effect, and obtaining long-term metabolic benefits are the direction for drug research and development in the future.
