The pre-clinical phase of development for non-alcoholic steatohepatitis (NASH) drugs faces many challenges. Biopharmaceutical companies have several options for rodent models, but they must weigh factors such as customization versus speed before deciding on the best approach.
Some of the challenges include:
- Diet: There is no prevailing wisdom in the field suggesting that one induction diet is superior to another.
- Duration of disease induction: Depending on the type of diet, it will take 6 to 9 months for models to exhibit NASH-like features.
- Translation: Novel biomarkers used in human clinical trials need further validation in rodent models.
