Animal tests are used to estimate drug-uptake in humans. If drug-uptake in animals is too low, promising drug candidates are excluded from further development.
But drug-uptake studies in animals are misleading: Blockbuster drugs such as Aripiprazole and Esomeprazole, the most sold drugs of 2013, have low oral bioavailability in animals, but drug-uptake in humans is high.
The expert system IMPACT-F replaces animal trials on drug-uptake.
Pharmaceutical companies have applied the expert system to evaluate human drug-uptake in various therapeutic areas such as diabetes, inflammation, antivirals, autoimmune diseases and cancer.
The expert system evaluates drug-uptake in humans significantly more reliably than animal trials. This further increases the prospects of human clinical trials, because the optimum oral dose for first-in-human clinical trials can be determined much more accurately.
Efficacy issues are identified as the main reason why clinical trials fail.
