An international expert working group representing 37 organisations (pharmaceutical/biotechnology companies, contract research organisations, academic institutions and regulatory bodies) collaborated in a data sharing exercise to evaluate the utility of two species within regulatory general toxicology studies. Anonymised data on 172 drug candidates (92 small molecules, 46 monoclonal antibodies, 15 recombinant proteins, 13 synthetic peptides and 6 antibody-drug conjugates) were submitted by 18 organisations. The use of one or two species across molecule types, the frequency for reduction to a single species within the package of general toxicology studies, and a comparison of target organ toxicities identified in each species in both short and longer-term studies were determined. Reduction to a single species for longer-term toxicity studies, as used for the development of biologicals (ICHS6(R1) guideline) was only applied for 8/133 drug candidates, but might have been possible for more, regardless of drug modality, as similar target organ toxicity profiles were identified in the short-term studies. However, definition and harmonisation around the criteria for similarity of toxicity profiles is needed to enable wider consideration of these principles. Analysis of a more robust dataset would be required to provide clear, evidence-based recommendations for expansion of these principles to small molecules or other modalities where two species toxicity testing is currently recommended.

在药物开发过程中使用一种物种进行长期毒理学测试的机会:跨行业评估。

代表37个组织(制药/生物技术公司,合同研究组织,学术机构和监管机构)的国际专家工作组合作进行了数据共享活动,以评估两种毒素在监管一般毒理学研究中的效用。18个组织提交了172种候选药物(92种小分子,46种单克隆抗体,15种重组蛋白,13种合成肽和6种抗体-药物结合物)的匿名数据。确定了在分子类型中使用一种或两种物种,在常规毒理学研究中将其还原为单个物种的频率以及在短期和长期研究中每种物种中鉴定出的靶器官毒性的比较。减少为单一物种进行长期毒性研究,用于生物制剂开发的药物(ICHS6(R1)指南)仅适用于8/133候选药物,但无论采用何种药物形式,都有可能用于更多药物,因为在短期内鉴定出相似的靶器官毒性学习。但是,需要围绕毒性谱相似性的标准进行定义和统一,以便能够更广泛地考虑这些原则。将需要对更强大的数据集进行分析,以提供清晰,基于证据的建议,以将这些原理扩展到目前建议使用两种物种毒性测试的小分子或其他方式。在短期研究中确定了相似的靶器官毒性特征。但是,需要围绕毒性谱相似性的标准进行定义和统一,以便能够更广泛地考虑这些原则。将需要对更强大的数据集进行分析,以提供清晰,基于证据的建议,以将这些原理扩展到目前建议使用两种物种毒性测试的小分子或其他方式。在短期研究中确定了相似的靶器官毒性特征。但是,需要围绕毒性谱相似性的标准进行定义和统一,以便能够更广泛地考虑这些原则。将需要对更强大的数据集进行分析,以提供清晰,基于证据的建议,以将这些原理扩展到目前建议使用两种物种毒性测试的小分子或其他方式。
