This assignment is expected to be for two years minimally and no more than three years.

Prodrug Post-doc: Project Overview and Aim

Prodrug development is a common strategy in the pharmaceutical industry for addressing poor physicochemical properties or to achieve product profile for an active moiety. Numerous in vitro approaches and matrices exist for the characterization of prodrug conversion, however, there is currently no guidance on best practice for the translation of in vitro and preclinical data to human, especially with respect to phosphate prodrugs. Significant prodrug conversion during manufacturing and storage prior to administration tend to be a liability for phosphate prodrugs and therefore mechanistic understanding of underlying pathways can be highly beneficial at compound selection stage.

The aim of this project is to assess predictivity of in vitro conversion in various matrices to preclinical and, as an extension, human bioavailability and to establish an in vitro-in vivo correlation. Furthermore, a secondary aim of this work would be to evaluate activity of phosphatases in different segments of the gut and establish relative activity factors (RAFs) across in vitro systems and animal and human intestinal tissue segments, which can be utilized in mechanistic PK models to scale enzyme kinetics of prodrug conversion. Established correlations can then be verified using various in-house prodrugs, as well as, model compounds. These predictive tools can also be leveraged to assess prodrug conversations prior to administration.

Specific aims will include:

  1. Evaluation and optimization of in vitro systems for prediction of in vivo performance of a prodrug

  2. Assess the translatability of in vitro bioconversion in various systems (including, but not limited to plasma, intestinal microsomes, intestinal mucosa and liver microsomes) to preclinical bioavailability by evaluating in vitro-in vivo correlation (IVIVc) between various enzymes systems and bioavailability in preclinical species

  3. Once IVIVc is established in preclinical species, evaluate IVIVc with human bioavailability for the selected system(s) using model compounds (phosphate prodrugs)

  4. Collect and incorporate solution and solid-state prodrug stability data under CMC relevant conditions into the prodrug conversion models developed herein. The applicability of the resulting models would then be broadened to provide a resource-sparing read on prodrug conversion liability prior to administration.

  5. Evaluate correlation between stability measures and bioconversion to develop guidelines of a risk matrix to inform discovery teams.

  6. Translation of in vitro bioconversion kinetics to human.

  7. Compare activity of phosphatases in segments of gut tissue of preclinical species and human – determine which species are more representative of human and evaluate inter-species variability.

  8. Establish relative activity factors (RAFs) for different GI segments in different species, which can be used to scale in vitro phosphatase bioconversion to in vivo.

  9. Verify RAFs using model phosphate prodrugs with available clinical data.

  10. Propose a best-practice approach for the characterization (i.e. most in vivo predictive in vitro system(s)) and translation (in silico) of prodrug bioconversion and bioavailability that would replace regular PK studies and enable prioritization of successful prodrugs for tox assessment and clinical development. (potential for publication)

Note: Improved triaging based on the findings of this research would ideally reduce the number of compounds moving to PCS and PRD for characterization.
