Workshop on Convolution-based modeling approach

March 11-13, 2019: Fort Lauderdale, FL (USA)


This three-day, hands-on course provides a working knowledge of the theories
and application of the state-of-the-art convolution-based modeling approach
to characterize complex PK profiles, to establish in-vitro in-vivo
correlation (IVIVC) and to optimize ER and LAI formulation development using
the exposure-response relationship.


The course is structured in the following sections:

1. Convolution based model

* Development of convolution-based models

* Modeling single and repeated doses administration using
convolution-based approach in NONMEM

* Development of an R based simulator for convolution-based models


2. Modeling complex absorption process

* Definition and implementation in NONMEM of typical and user
defined input function models, to characterize delayed, multiple peaks and
time dependent absorption process

* Characterize the complex in-vivo absorption processes of extended
release formulations (ER) and Long Acting Injectable (LAI) formulations
using convolution-based approach


3. Implementing Level A IVIVC

* Definition of Level A IVIVC

* Implementation of a Level A IVIVC using convolution-based models

* The concept of time-scaling

* Definition of time scaling functions for assessing IVIVC in NONMEM

* Evaluate the quality of an IVIVC model and the predictive
performances of an IVIVC model


4. Optimizing drug performances

* Definition of drug/formulation optimization strategies using
surface-response analysis, clinical trial simulation and convolution-based

* Development of an R based optimizer

* Determine the relationship between drug delivery and clinical
benefit using the outcome of an IVIVC analysis

* Determine dose, dosage regimen and dosing strategies for
optimizing the clinical benefit using the outcomes of the IVIC analysis


Interactive and real life examples, taken from actual industry experience
using R and NONMEM will be presented and discussed in the hands-on sections
to illustrate how to deal with delayed, multiple peaks and time dependent
absorption process, how to establishing a Level A IVIVC using a
model-informed approach and how to develop optimized formulations with an
in-vivo drug release suitable to maximize the clinical benefit of a
