Large-molecule antibody biologics have revolutionized medicine owing to their superior target specificity, pharmacokinetic and pharmacodynamic properties, safety and toxicity profiles, and amenability to versatile engineering. In this review, we focus on preclinical antibody developability, including its definition, scope, and key activities from hit to lead optimization and selection. This includes generation, computational and approaches, molecular engineering, production, analytical and biophysical characterization, stability and forced degradation studies, and process and formulation assessments. More recently, it is apparent these activities not only affect lead selection and manufacturability, but ultimately correlate with clinical progression and success. Emerging developability workflows and strategies are explored as part of a blueprint for developability success that includes an overview of the four major molecular properties that affect all developability outcomes: 1) conformational, 2) chemical, 3) colloidal, and 4) other interactions. We also examine risk assessment and mitigation strategies that increase the likelihood of success for moving the right candidate into the clinic.
由于其优越的靶向特异性、药代动力学和药效学特性、安全性和毒性特征以及对多种工程的适用性,大分子抗体生物制剂已经彻底改变了医学。在这篇综述中,我们专注于抗体的临床前可开发性,包括其定义、范围以及从命中到先导优化和选择的关键活动。这包括生成、计算和实验方法、分子工程、生产、分析和生物物理特性、稳定性和强制降解研究以及工艺和配方评估。最近,很明显,这些活动不仅会影响先导化合物的选择和可制造性,而且最终还与临床进展和成功相关。作为可开发性成功蓝图的一部分,探讨了新兴的可开发性工作流程和策略,其中概述了影响所有可开发性结果的四个主要分子特性:1)构象,2)化学,3)胶体,和 4)其他相互作用。我们还研究了风险评估和缓解策略,这些策略增加了将合适的候选药物推向临床的成功可能性。
