These inhibitions are not correlated with these azoles but were used to assess power and parameter precision at the different extents of clearance inhibition. Optimal sampling times were determined using the D-optimal design based on the population PK model by Guilhaumou et al. A set dose of 1.4 mg/m2, capped at 2.0mg, infused over 1 hour was used in all simulations per treatment guidelines for vincristine.
Input-Output Model
This model is designed to develop the wanted results. In this study, the input-output model simulates the vincristine concentration-time profile using a non-linear mixed effect (NLME) PK model developed by Guilhaumou et al. This was chosen because it has the known bi-exponential PK of vincristine. This design used body surface area (BSA) scaling on all structural model parameters. The variability of vincristine’s clearance and residual error was calculated for using inter-occasion variability (IOV).
