IVIVC Toolkit

Phoenix IVIVC Toolkit

The Gold Standard for Predicting Pharmacokinetic (PK) Parameters from In Vitro Dissolution Data in Drug Development and Formulations.

The Phoenix® IVIVC Toolkit creates and substantiates the Level A correlation as outlined in the FDA Guidance for Industry1 to correlate the in vitro dissolution profile of a dosage form with the in vivo pharmacokinetic (PK) profile. It can be used to predict the impact a change in formulation will have or predict the dissolution rate that is necessary to achieve a desired PK profile. The Level A IVIVC can support a biowaiver for changes in manufacturing site, raw material suppliers and minor changes in formulation.2

Web-IVIVC-GraphThe IVIVC Toolkit provides a comprehensive workbench that can be used to demonstrate virtual bioequivalence:

  • Deconvolution and Convolution modeling methods
  • Flexibility to use built-in or custom correlation models
  • IVIVC Wizard for data and workflow management
  • Reusable workflow templates
  • High quality outputs for creating reports and publication-quality tables, listings and figures
  • Levy plots to assess time-scale of dissolution experiments
  • Compliance, standardization and validation

Streamline the development process,
reduce costs and attain regulatory biowaivers

Save money: Inexpensive IVIVC studies can be used as a surrogate for expensive and time consuming bioavailability or bioequivalence (BA/BE) studies in animals or humans. The IVIVC Toolkit minimizes the number of BA/BE studies by quickly generating IVIVC results using workflows and high quality outputs.

Accelerate drug development: The IVIVC Toolkit provides predictive IVIVC methods that can help bring a drug to market faster by reducing the development effort from weeks to days.

Greater standardization and error-free results versus manual methods: Unlike Microsoft® Excel®, the IVIVC Toolkit provides many programmed features not found in Excel, including dialog-guided wizards and validated tools to streamline the workflow, automatic estimation of Unit Impulse Response (UIR), Levy Plots, workflow support for a complete two-stage IVIVC, and much more.

Facilitates collaboration: PK and IVIVC parameters can be seamlessly transferred within Phoenix. This provides a common collaboration platform for the formulation development and pharmacology teams.
