Translating pharmacology models effectively to predict therapeutic benefit

Area of Science:

• Pharmacology
• Translational Medicine
• Preclinical Research

Background:

• In vitro and in vivo models are vital for evaluating targeted proteins in disease.
• Assessing the translational relevance of these models is essential for drug development.
• Limitations in current models can hinder accurate prediction of drug efficacy and dosing.

Purpose of the Study:

• To review selected animal models used in key therapeutic areas.
• To highlight challenges in model translatability and dose determination.
• To discuss potential solutions for improving preclinical drug evaluation.

Main Methods:

• Literature review of animal models in ophthalmology, infectious diseases, oncology, autoimmune diseases, and neuroscience.
• Analysis of model limitations concerning drug disposition, PK/PD profiles, mechanism, and efficacy.
• Exploration of patient-specific dosing as a potential advancement.

Main Results:

• Each reviewed area presents unique challenges for model translatability.
• Determining clinically efficacious doses is a significant hurdle across models.
• Current models may not fully predict human responses to investigational drugs.

Conclusions:

• Careful selection of animal models based on translational relevance is critical.
• Overcoming model limitations is essential for accurate prediction of drug efficacy.
• Patient-specific dosing strategies may enhance the predictive value of preclinical models.
