The model was developed based on physicochemical and in vitro parameters, as well as clinical data, including pharmacokinetic data in patients with B\u2010cell malignancies and in healthy volunteers from two clinical drug\u2010drug interaction (DDI) studies of zanubrutinib as a victim of CYP modulators (itraconazole, rifampicin) or a perpetrator (midazolam). This PBPK model was successfully validated to describe the observed plasma concentrations and clinical DDIs of zanubrutinib. Model predictions were generally within 1.5\u2010fold of the observed clinical data. The PBPK model was used to predict untested clinical scenarios; these simulations indicated that strong, moderate, and mild CYP3A inhibitors may increase zanubrutinib exposures by approximately four\u2010fold, two\u2010 to three\u2010fold, and &lt;1.5\u2010fold, respectively. Strong and moderate CYP3A inducers may decrease zanubrutinib exposures by two\u2010 to three\u2010fold or greater. The PBPK simulations showed that clinically relevant concentrations of zanubrutinib, as a DDI perpetrator, would have no or limited impact on the enzyme activity of CYP2B6 and CYP2C8. Simulations indicated that zanubrutinib exposures are not impacted by acid\u2010reducing agents. Development of a PBPK model for zanubrutinib as a DDI victim and perpetrator in parallel can increase confidence in PBPK models supporting zanubrutinib label dose recommendations.<\/jats:p>","DOI":"10.1002\/psp4.12605","type":"journal-article","created":{"date-parts":[[2021,3,9]],"date-time":"2021-03-09T05:32:58Z","timestamp":1615267978000},"page":"441-454","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Comprehensive PBPK model to predict drug interaction potential of Zanubrutinib as a victim or perpetrator"],"prefix":"10.1002","volume":"10","author":[{"given":"Kun","family":"Wang","sequence":"first","affiliation":[{"name":"Shanghai Qiangshi Information Technology Co., Ltd Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueting","family":"Yao","sequence":"additional","affiliation":[{"name":"Drug Clinical Trial Center Peking University Third Hospital Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Drug Clinical Trial Center Peking University Third Hospital Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongyang","family":"Liu","sequence":"additional","affiliation":[{"name":"Drug Clinical Trial Center Peking University Third Hospital Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuying","family":"Gao","sequence":"additional","affiliation":[{"name":"Shanghai Qiangshi Information Technology Co., Ltd Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Srikumar","family":"Sahasranaman","sequence":"additional","affiliation":[{"name":"BeiGene USA, Inc San Mateo CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying C.","family":"Ou","sequence":"additional","affiliation":[{"name":"BeiGene USA, Inc San Mateo CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,5,2]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jmedchem.9b00687"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood.2020006844"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood.2019001160"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00280-019-04015-w"},{"key":"e_1_2_10_6_1","article-title":"Evaluation of drug interaction potential of zanubrutinib with cocktail probes representative of CYP3A4, CYP2C9, CYP2C19, P\u2010gp and BCRP","author":"Ou YC","year":"2020","journal-title":"Br J Clin Pharmacol"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/psp4.30"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/clpt.2010.298"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1124\/dmd.116.071076"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/00498250600683197"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.2174\/138920010794328913"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1208\/s12248-009-9099-y"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/psp4.12408"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40262-015-0352-5"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0070330"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9236(97)90160-0"},{"key":"e_1_2_10_17_1","volume-title":"Brukinsa [package insert]","author":"BeiGene USA, Inc","year":"2019"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/bdd.1830"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/cpt.128"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/cpt.917"},{"key":"e_1_2_10_21_1","article-title":"Population pharmacokinetic analysis of the BTK inhibitor zanubrutinib in healthy volunteers and patients with B\u2010cell malignancies","author":"Ou YC","journal-title":"Clin Transl Sci"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjopharm.2004.12.005"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.1080\/03602530902722679"},{"key":"e_1_2_10_24_1","unstructured":"US Food and Drug Administration Center for Drug Evaluation and Research.Approval package for KISQALI.https:\/\/www.accessdata.fda.gov\/drugsatfda_docs\/nda\/2019\/209092Orig1s001.pdf.
