The platform predicts molecule PK profiles with high accuracy and without the need for experimental data.</p><p><strong>Methods: </strong>This study developed a whole-body PBPK model and ML models of plasma protein fraction unbound ( <math><msub><mi>f</mi> <mrow><mi>up</mi></mrow> </msub> </math> ), Caco-2 cell permeability, and total plasma clearance to predict the PK of small molecules after intravenous administration. Pharmacokinetic profiles were simulated using a \"bottom-up\" PBPK modeling approach with ML inputs. Additionally, 40 compounds were used to evaluate the platform's accuracy.</p><p><strong>Results: </strong>Results showed that the ML-PBPK model predicted the area under the concentration-time curve (AUC) with 65.0 <math><mo>%</mo></math> accuracy within a 2-fold range, which was higher than using in vitro inputs with 47.5 <math><mo>%</mo></math> accuracy.</p><p><strong>Conclusion: </strong>The ML-PBPK model platform provides high accuracy in prediction and reduces the number of experiments and time required compared to traditional PBPK approaches. The platform successfully predicts human PK parameters without in vitro and in vivo experiments and can potentially guide early drug discovery and development.</p>","PeriodicalId":20027,"journal":{"name":"Pharmaceutical Research","volume":" ","pages":"1369-1379"},"PeriodicalIF":3.5,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11534847/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141451175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
