Improve Your Phase I Success Rate: Fast Early Technology Screening for Poorly Bioavailable Molecules


During the pre-clinical stage of drug development, getting to the desired quality target product profile can be challenging, specifically considering the bioavailability/solubility issues, limited API availability and the speed of execution.

There is a tendency in the industry to start with a simple formulation like powder in a bottle and switch over to another formulation once more data is available – this lets the drug developers to stay with the in-house formulation early on and the option to partner with an expert on a specific technology later. However, this linear approach increases the risk of burning time and resources especially with the increasing number of poorly soluble molecules.

It is, increasingly, essential to examine and rank multiple delivery options in parallel, to collect data about the relative dose capability, PK enhancement and manufacturability in order to select drug candidates to advance to clinical Phase 1. This parallel screening strategy de-risks the early drug development and increases the success rate for later stages as compared with the linear model where the predicable failures from iterative approach make the drug development process longer and costlier.

This webinar will provide an overview of a parallel formulation feasibility assessment approach that is designed to reveal the most suitable pathway to enhance bioavailability and accelerate development.

In just 12 weeks, prototypes of selected formulations are available for animal PK studies.

  • Know your molecule (ASSESS). Insights from experts on designing an efficient dosage form selection scenario based upon molecular, chemical, and physical properties
  • Complex molecules require a sophisticated toolkit (ENHANCE). How to select a delivery technology that will accelerate development, optimize exposure and enable dose-escalation
  • Optimize your molecule’s potential (DELIVER). Why applying the right technologies early in the process can optimize the therapeutic profile beyond exposure.

Register for the webinar to learn the strategies for parallel drug development approach and get insights from case studies.
