This research investigates the effect of dulaglutide on gastric emptying and its impact on the pharmacokinetics (PK) of orally administered molecules utilizing a combination of population pharmacokinetic (PopPK) and physiologically based pharmacokinetic (PBPK) modeling approaches. In clinical studies, the gastric emptying delay (GED) was evaluated in healthy participants and patients with T2DM at various dose levels of dulaglutide. A PopPK model estimated the exposure-dependent delay in gastric emptying, which was then input into the orally administered small molecule PBPK models. These PBPK models, informed by internal clinical studies and publicly available data, quantified the effect of dulaglutide-induced GED on the area under the curve (AUC), maximum concentration (C<sub>max</sub>), and time to maximum concentration (t<sub>max</sub>) of the co-administered drugs. The modeling approach was verified for reproducing observed GED-mediated drug-drug interactions (DDIs) at low doses of dulaglutide and to predict DDIs at a 4.5 mg dulaglutide dose. The clinical studies demonstrated that the 1.5 mg dulaglutide dose has no clinically relevant effect on the pharmacokinetics of small molecules, and the modeling led to a similar conclusion at 4.5 mg dulaglutide. This work demonstrates that modeling approaches can be used to predict potential GLP-1-mediated DDIs related to gastric emptying delay, increasing the efficiency of the clinical pharmacology programs.</p>","PeriodicalId":10774,"journal":{"name":"CPT: Pharmacometrics & Systems Pharmacology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144945915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evaluating whether treatment outcomes in clinical practice are similar to those in RCTs shortly after a new medicine is introduced is important for making informed decisions. Therefore, we aimed to develop a Bayesian model that compares survival data from clinical practice that accumulates over time with static survival data from RCTs, thereby providing rapid and easily interpretable results that can inform clinical and policy-related decision-making. We developed a Bayesian survival model that sequentially updates estimates as new data become available. We designed the model to incorporate static RCT data with accumulating clinical practice data. We used sequential hypothesis testing with Bayes factors to assess the strength of the evidence for different hazard ratio (HR) thresholds (i.e., ranging from HR > 1.0 to > 2.0 and HR < 0.5 to < 1.0). We applied the model to two datasets comprising survival data from clinical practice and an RCT for lung cancer patients treated with pembrolizumab plus chemotherapy (dataset 1) and pembrolizumab monotherapy (dataset 2). For dataset 1, the posterior model checks showed a misfit between the model and the data after 15 months, potentially due to channeling bias. The model fit should be improved before reliable estimates can be obtained. For dataset 2, the model estimated precise HRs 10 months before the end of data accumulation. Sequential hypothesis testing with Bayes factors provided easily interpretable results, with very strong evidence for an HR > 1.0 and strong evidence for an HR > 1.2.

Despite a huge wealth of resources and promising preclinical testing, effective disease-modifying therapies do not exist. This failure is owing to a combination of poor biological understanding of this response, unsuitable animal models, and poor scaling from pathway up to clinical levels.

Empirical models of solid tumor size dynamics-a key prognostic biomarker-have played a central role in addressing these challenges. However, a systematic comparison of commonly used tumor size models, in terms of descriptive and predictive performance as well as generalizability within a population framework, has not been conducted to date. The present research sought to develop a methodological framework for the optimization of tumor models, offering a basis for more accurate predictions of tumor dynamics. The corresponding modeling workflow was practically tested against clinical data of erlotinib, a treatment administered to patients with advanced NSCLC. Five widely used tumor size models were evaluated, of which only three-the Bi-Exponential (BiExp), the Linear-Exponential (LExp), and Claret's Tumor Growth Inhibition (TGI) model-demonstrated reproducibility of the base model during a repeated cross-validation approach. Among these, the TGI model exhibited superior descriptive and predictive performance. However, a thorough literature search showed that erlotinib clinical data in NSCLC have been analyzed using only the BiExp and LExp models. Furthermore, extrapolation from 3 to 16 months revealed outlier predictions for the BiExp and TGI models, while the LExp model showed higher consistency, suggesting that models utilizing an exponential growth function may have a more limited extrapolation range than those assuming linear growth. Despite a clear ranking of models based on descriptive and predictive performance, no hierarchy emerged with respect to discriminatory ability. All three models showed high accuracy in distinguishing RECIST-based objective responders, while accuracy in predicting the emergence of acquired resistance remained uniformly low.

The risk assessment of bosentan-induced liver injury requires a thorough understanding of the underlying mechanisms, for which there is accumulating evidence. Integrating these mechanisms with clinical liver bosentan concentration would enable a more dynamic and relevant risk assessment. This study designed a workflow of physiologically-based pharmacokinetic (PBPK) model development to capture bosentan's hepatic disposition and predict the (intra)hepatic bosentan exposure. Specifically, clinical plasma and excretion data of bosentan were used to minimize the uncertainty in estimating the hepatic clearance. The model predictions were well overlapped with observations in the systemic circulation and excretion. Furthermore, the model-derived intrinsic hepatic clearance was comparable with the one derived from a clinical study. These results reflected confidence in the model's capability to predict hepatic bosentan exposure. The model-simulated steady-state unbound exposure to bosentan in hepatocytes and liver tissue ranged from 1.65 to 34.1 ng/mL following twice-daily 125-mg oral doses. The ratio of the simulated unbound concentration between the liver matrices and systemic plasma was between 0.80 and 2.93 across the therapeutic dosing regimens. In summary, a bosentan PBPK model was successfully developed with the designed workflow and was able to predict the hepatic disposition of bosentan. The developed model can be applied to generate hepatic bosentan exposure that bridges the toxicological mechanistic findings from in vitro to in vivo, assisting in risk assessment.</p>","PeriodicalId":10774,"journal":{"name":"CPT: Pharmacometrics & Systems Pharmacology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144788478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
