ADME Characterization
Our pharmacokinetics services focus on the four critical aspects of drug disposition in biological systems. We design studies to assess how your compound is absorbed through various routes of administration, where it distributes in the body, how it is metabolized, and through what pathways it is eliminated.
Using our advanced analytical capabilities including HPLC, GPC, and specialized detection methods, we can track your compound and its metabolites across multiple biological matrices. Our tissue collection protocols ensure proper sample handling for downstream analysis, while our fixation and processing capabilities support detailed tissue-level PK assessment.
Bioanalytical Method Development
Accurate quantification of drug concentrations is essential for reliable PK studies. Our analytical chemistry team develops and validates bioanalytical methods tailored to your specific compound and study requirements. We utilize state-of-the-art analytical platforms to ensure sensitive, specific, and reproducible quantification across the concentration ranges relevant to your studies.
Our drug formulation characterization services using GPC, HPLC, and rheometry support method development by providing detailed understanding of your compound’s physicochemical properties. This information guides selection of appropriate analytical conditions and sample preparation procedures.
Tissue Distribution Studies
Understanding where your drug distributes in the body provides critical insights for both efficacy and safety assessment. Our comprehensive tissue collection capabilities enable detailed biodistribution studies across multiple organ systems. We can assess drug levels in blood, tissues, cerebrospinal fluid, and organs using validated analytical methods.
Our ex vivo biodistribution services utilize fluorescent or labeled compound tracking to provide visual and quantitative assessment of drug distribution patterns. This approach is particularly valuable for understanding tissue-specific accumulation and clearance patterns that may not be apparent from plasma PK alone.
Advanced Analytical Techniques
Our analytical capabilities extend beyond traditional PK measurements to include specialized techniques for comprehensive drug characterization. We utilize qPCR analysis with QuantStudio 7 and ProFlex systems for gene expression studies related to drug metabolism and transport. Western blot analysis using FluorChem E systems enables protein-level assessment of drug effects on metabolic enzymes and transporters.
For nanoparticle and complex formulations, our biophysical services include particle size, charge, and distribution analysis using NanoBrook and qNano Gold systems. These measurements are essential for understanding the relationship between formulation properties and in vivo performance.
Metabolic Profiling
Understanding drug metabolism is crucial for predicting drug-drug interactions, identifying active metabolites, and assessing potential toxicity risks. Our metabolic profiling capabilities include ex vivo analysis of tissue and cellular metabolism using Seahorse XFe96 technology.
We can assess metabolic changes in specific tissues following drug administration, providing insights into both intended and unintended metabolic effects. This information is particularly valuable for drugs targeting metabolic pathways or those with potential metabolic toxicity concerns.
Specialized PK Applications
Our capabilities support specialized PK applications including brain penetration studies, tumor pharmacokinetics, and protein therapeutics assessment. For central nervous system drugs, we can assess blood-brain barrier penetration through cerebrospinal fluid sampling and brain tissue analysis.
Tumor-bearing animal studies enable assessment of drug accumulation in both tumor and normal tissues, providing critical information for oncology drug development. Our surgical capabilities support implantation procedures and specialized sampling techniques required for these complex studies.
Sample Collection and Processing
Proper sample collection and handling are critical for reliable PK data. Our team is experienced in various sampling techniques including blood collection via multiple routes, tissue harvesting, and specialized fluid collection. We follow standardized protocols for sample processing and storage to ensure data integrity.
Our tissue fixation and processing capabilities support both PK analysis and correlative histological assessment. This integrated approach enables evaluation of drug distribution patterns alongside tissue morphology and cellular responses.
Data Analysis and Modeling
Raw PK data requires sophisticated analysis to extract meaningful parameters for drug development decisions. Our team provides comprehensive data analysis including non-compartmental analysis for basic PK parameters and compartmental modeling for mechanistic understanding of drug disposition.
We calculate standard PK parameters including AUC, Cmax, Tmax, half-life, clearance, and volume of distribution. For more complex studies, we can perform population PK analysis and physiologically-based pharmacokinetic modeling to support dose selection and clinical translation.
Regulatory Compliance
Our PK studies are designed and conducted to meet regulatory requirements for drug development. We follow Good Laboratory Practice principles and maintain detailed documentation to support regulatory submissions. Our quality systems ensure data integrity and traceability throughout the study process.
We provide comprehensive study reports that include detailed methodology, results, and interpretation suitable for inclusion in regulatory submissions. Our team can also provide guidance on PK study design to address specific regulatory requirements for your indication and development pathway.
Integrated Study Design
What distinguishes our PK services is the ability to integrate pharmacokinetics assessment with other endpoints in single studies. We can combine PK analysis with efficacy measurements, toxicity assessment, and behavioral endpoints to provide comprehensive understanding of your compound’s in vivo performance.
This integrated approach is particularly valuable for early-stage studies where multiple questions need to be addressed efficiently. Our custom study designs maximize the information obtained while minimizing animal use and study costs.
