          摘  要  表皮生长因子受体-酪氨酸激酶抑制剂(EGFR-TKI)是一类小分子肿瘤靶向治疗药物,是EGFR突变晚期非小细胞肺癌
         (NSCLC)的一线治疗药物,代表药物有吉非替尼、达可替尼、奥希替尼等。临床治疗中,肿瘤患者若存在药物联用、肝肾损伤等特
          殊情况,可能需调整EGFR-TKI的剂量。生理药代动力学(PBPK)模型可以预测药物在人体内的药代动力学(PK)过程,是临床剂
          量调整的重要工具。本文梳理了 PBPK 模型的建模方法、流程以及常用建模软件,总结了截至 2024 年 6 月 30 日 PBPK 模型在
          EGFR-TKI精准用药中的应用现状,发现PBPK模型的建模方法常用“自下而上”法和中间法,流程包括收集参数、房室选择、模型
          验证、模型应用4个步骤,常用软件有Simcyp、GastroPlus及开源软件PK-Sim等。PBPK模型可用于预测EGFR-TKI与代谢酶诱导
          剂或抑制剂、抑酸药、中西药联用时的药物-药物相互作用,结合基因组学调整药物剂量,预测特殊人群(肝肾功能不全患者、儿童
          患者)PK过程,评价药物的疗效和安全性,以及从动物模型外推预测人体PK等。

          ABSTRACT   Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) represent a class of small-molecule targeted
          therapeutics for oncology treatment, and serve as first-line therapy for advanced non-small cell lung cancer (NSCLC) with EGFR-
          sensitive  mutations,  with  representative  agents  including  gefitinib,  dacomitinib,  and  osimertinib.  In  clinical  practice,  dose
          adjustment  of  EGFR-TKI  may  be  required  for  cancer  patients  under  special  circumstances  such  as  drug  combinations  or  hepatic/
          renal impairment. Physiologically-based pharmacokinetic (PBPK) model, capable of predicting pharmacokinetic (PK) processes in
          humans, has emerged as a vital tool for clinical dose optimization. This article sorts the modeling methodologies, workflows, and
          commonly  used  software  tools  for  PBPK  model,  and  summarizes  the  current  applications  of  PBPK  model  in  EGFR-TKI  precision
          therapy as of June 30, 2024. Findings demonstrate that PBPK modeling methods commonly employ the “bottom-up” approach and
          the middle-out approach. The process typically involves four steps: parameter collection, compartment selection, model validation,
          and model application. Commonly used software for modeling includes Simcyp, GastroPlus, and open-source software such as PK-
          Sim.  PBPK  model  can  be  utilized  for  predicting  drug-drug  interactions  of  EGFR-TKI  co-administered  with  metabolic  enzyme
          inducers  or  inhibitors,  acid-suppressive  drugs,  or  traditional  Chinese  and  Western  medicines.  It  can  also  adjust  dosages  in
          conjunction with genomics, predict PK processes in special populations (such as patients with liver or kidney dysfunction, pediatric
          patients), evaluate the efficacy and safety of drugs, and extrapolate PK predictions from animal models to humans.
