A new drug can have its origin in either pharma, biotech or academia. In general, discovery scientists working in pharma and biotech are advantaged over their academic counterparts and the relative advantages and disadvantages associated are discussed in depth. Against all odds, an increasing number of important drugs have had their origins in academia. This article reports three case studies from the Liotta Research Group (LRG), which explores the special circumstances that allowed these drug development campaigns to be successful. The first involves the antiretroviral agent, emtricitabine. In this case efficient synthetic methodology, developed in the LRG, coupled with some key university and commercial sector partnerships, enabled a group of academic collaborators to discover and develop a highly effective HIV reverse transcriptase inhibitor. The second case study involves the discovery and development of the breakthrough hepatitis C drug, sofosbuvir. Based on key input from Professors Schinazi and Liotta at Emory University, scientists at the Emory startup, Pharmasset, identified the nucleoside core of the drug that would become sofosbuvir. Subsequent analysis of its phosphorylation profile by Pharmasset scientists suggested that converting it to its corresponding monophosphate prodrug would circumvent a kinase block and enable it to be an effective hepatitis C polymerase inhibitor. The third case study describes the formation of DRIVE (Drug Innovation Ventures at Emory)/EIDD (Emory Institute for Drug Development), which were created to circumvent unintended impediments for carrying out academic drug discovery and development. Although DRIVE/EIDD is a wholly-owned, not-for-profit subsidiary of Emory University, it contains many attributes that enables it to operate much more nimbly than a typical academic laboratory. With an experienced drug development team and no shareholders to distract them, DRIVE/EIDD was able to focus its attention of the development of drugs to address viral diseases of global concern. In particular, their strategy to identify and develop an antiviral agent active against multiple single-stranded RNA viruses led to molnupiravir, a broadly active, oral drug that received Emergency Use Authorization for the treatment of SARS-CoV-2 infections (i.e., COVID-19).
一种新药可能源自制药、生物技术或学术界。一般来说,在制药和生物技术领域工作的发现科学家比他们的学术同行具有优势,并且深入讨论了相关的优势和劣势。尽管困难重重,越来越多的重要药物源自学术界。本文报道了利奥塔研究小组(LRG)的三个案例研究,探讨了允许这些药物开发活动取得成功的特殊情况。第一个涉及抗逆转录病毒药物恩曲他滨。在这种情况下,LRG 开发的高效合成方法,加上一些关键的大学和商业部门的合作关系,使一群学术合作者能够发现和开发出一种高效的 HIV 逆转录酶抑制剂。第二个案例研究涉及突破性丙型肝炎药物索非布韦的发现和开发。基于埃默里大学的 Schinazi 教授和利奥塔教授的关键投入,埃默里初创公司 Pharmasset 的科学家确定了药物的核苷核心,该核心将成为索非布韦。随后,Pharmasset 科学家对其磷酸化谱进行分析表明,将其转化为相应的单磷酸前药可以绕过激酶阻断,使其成为有效的丙型肝炎聚合酶抑制剂。第三个案例研究描述了 DRIVE(埃默里大学药物创新风险投资公司)/EIDD(埃默里药物开发研究所)的形成,其目的是规避进行学术药物发现和开发的意外障碍。尽管 DRIVE/EIDD 是埃默里大学的全资非营利性子公司,但它包含了许多使其能够比典型的学术实验室更灵活运作的属性。由于拥有一支经验丰富的药物开发团队,且没有股东分心,DRIVE/EIDD 能够专注于开发治疗全球关注的病毒疾病的药物。特别是,他们确定和开发一种针对多种单链 RNA 病毒的抗病毒药物的策略导致了 molnupiravir 的产生,这是一种广泛有效的口服药物,已获得用于治疗 SARS-CoV-2 感染(即 COVID-19)的紧急使用授权。
