Even modest improvements in the probability of success of selecting drug targets which are ultimately approved can substantially reduce the costs of research and development. Drug targets with human genetic evidence of disease association are twice as likely to lead to approved drugs. A key enabler of identifying and validating these genetically validated targets is access to association results from genome-wide genotyping, whole-exome sequencing, and whole-genome sequencing studies with observable traits (often diseases) across large numbers of individuals. Today, linkage between genotype and real-world data (RWD) provides significant opportunities to not only increase the statistical power of genome-wide association studies by ascertaining additional cases for diseases of interest, but also to improve diversity and coverage of association studies across the disease phenome. As RWD-genetics linked resources continue to grow in diversity of participants, breadth of data captured, length of observation, and number of participants, there is a greater need to leverage the experience of RWD experts, clinicians, and highly experienced geneticists together to understand which lessons and frameworks from general research using RWD sources are relevant to improve genetics-driven drug discovery and development. This paper describes new challenges and opportunities for phenotypes enabled by diverse RWD sources, considerations in the use of RWD phenotypes for disease gene identification across the disease phenome, and challenges and opportunities in leveraging RWD phenotypes in target validation. The paper concludes with views on the future directions for phenotype development using RWD, and key questions requiring further research and development to advance this nascent field.
即使在选择最终获得批准的药物靶点的成功率方面略有提高,也可以大大降低研发成本。具有人类遗传疾病关联证据的药物靶点成为批准药物的可能性是两倍。识别和验证这些经过基因验证的靶点的关键促成因素是能够访问来自全基因组基因分型、外显子组测序和全基因组测序研究的关联结果,这些研究涉及大量个体的可观察特征(通常是疾病)。如今,基因型与真实世界数据(RWD)之间的联系不仅提供了通过确定感兴趣疾病的更多病例来增加全基因组关联研究的统计能力的重要机会,而且还改善了整个疾病表型的关联研究的多样性和覆盖范围。随着 RWD-遗传学关联资源在参与者多样性、捕获数据的广度、观察时间长度和参与者数量方面不断增加,因此更需要利用 RWD 专家、临床医生和经验丰富的遗传学家的经验,以了解使用 RWD 源进行一般研究的哪些经验教训和框架对于改进基于遗传学的药物发现和开发具有重要意义。本文描述了由多样化的 RWD 源支持的表型的新挑战和机遇,考虑了在整个疾病表型中使用 RWD 表型进行疾病基因识别的问题,以及在验证 RWD 表型中的目标方面的挑战和机遇。本文最后展望了使用 RWD 开发表型的未来方向,并提出了需要进一步研究和开发的关键问题,以推动这一新兴领域的发展。
