Machine learning algorithms to estimate everolimus exposure trained on simulated and patient pharmacokinetic profiles.

ABSTRACT: Everolimus is an immunosuppressant with a small therapeutic index and large between-patient variability. The area under the concentration versus time curve (AUC) is the best marker of exposure but measuring it requires collecting many blood samples. The objective of this study was to train machine learning (ML) algorithms using pharmacokinetic (PK) profiles from kidney transplant recipients, simulated profiles, or both types, and compare their performance for everolimus AUC_0-12h estimation using a limited number of predictors, as compared to an independent set of full PK profiles from patients, as well as to the corresponding maximum a posteriori Bayesian estimates (MAP-BE). XGBoost was first trained on 508 patient interdose AUCs estimated using MAP-BE, and then on 500-10,000 ri
