Population Pharmacokinetic (PopPK) Modeling
Quantify variability, optimize dosing, and predict how your drug performs across diverse, real-world patient populations with Population PK modeling.
What Is Population PK?
No two patients respond to drugs the same way. Population Pharmacokinetics (PopPK) uses mathematical modeling to analyze how drugs are absorbed, distributed, metabolized, and excreted (ADME) across diverse populations. This approach helps explain differences in drug exposure, even when patients receive the same dose.
PopPK models are built using real-world clinical data and account for both:
By identifying key covariates—such as age, weight, sex, genetics, disease state, and co-administered medications—PopPK modeling supports dose optimization and helps predict how drugs will perform across different patient populations.
Applications of Population PK
At Xyzagen, we apply PopPK modeling throughout drug development to support clinical decision-making and regulatory submissions. Whether you’re working with healthy volunteers, pediatrics, elderly patients, or special populations, our PopPK insights help ensure safe, effective dosing.
PopPK is Particularly Valuable For:
Xyzagen’s PopPK Modeling Capabilities
We use industry-standard tools like NONMEM and Phoenix NLME to develop, validate, and interpret PopPK models that are scientifically rigorous and regulatory ready. Our PopPK Modeling capabilities include:
Model Development & Validation
We build and qualify models based on clinical and preclinical data to characterize drug behavior and exposure variability.
Covariate Analysis
We identify and quantify the impact of intrinsic and extrinsic factors (e.g., renal function, body weight, comedications) on PK parameters.
Dose Optimization & Simulation
We simulate dosing scenarios across populations to inform study design, dosing guidelines, and labeling.
Sparse Sampling Strategy Design
We help design efficient PK studies with fewer blood draws, reducing burden on patients while preserving data quality.
Regulatory Support
We generate submission-ready model reports and work closely with sponsors to respond to agency questions and feedback.
