Dose Formulation Analysis is an essential step in regulated nonclinical studies to ensure correct doses are administered to underpin toxicokinetic assessments. Based on years of experience, KCAS has built a stand-alone team dedicated to…

Designing a tissue assay in accordance to the FDA bioanalytical method validation (BMV) guidance involves three key questions. First, can control tissue be easily obtained in bulk quantities or should a surrogate tissue approach be considered? Second, what sample processing procedures should be considered relative to the known stability of…

Surprisingly, there are a number of drug development companies that do not obtain stable isotope-labeled internal standards (SIL-IS) for their bioanalytical methods. Instead they settle for using a surrogate internal standard (a compound that closely resembles the measured analyte) which can lead to unreliable data and be detrimental to a…
