Translational issues in precision medicine in neuropathic pain

Area of Science:

• Neuroscience
• Pharmacology
• Translational Medicine

Background:

• Neuropathic pain is a challenging condition with limited effective treatments.
• The traditional bench-to-bedside research model faces a significant translational gap.
• Bridging this gap may involve back-translating clinical observations to preclinical models.

Purpose of the Study:

• To review historical rodent data to re-evaluate drug effects on sensory neuronal endpoints.
• To align preclinical findings with clinical observations in neuropathic pain.
• To guide future clinical studies by informing preclinical research strategies.

Main Methods:

• Retrospective analysis of historical rodent datasets.
• Examination of drug effects on sensory neuronal endpoints in animal models.
• Comparison of preclinical data with clinical observations.

Main Results:

• Quantitative sensory testing in patients can improve treatment selection and outcomes.
• Preclinical phenotyping using quantitative sensory testing is not yet mainstream.
• Reconsidering rodent data may reveal better alignment with clinical observations for drug efficacy.

Conclusions:

• Aligning preclinical research with clinical observations is crucial for effective neuropathic pain drug development.
• Back-translation from clinical findings to animal models can help bridge the translational gap.
• Future studies should integrate quantitative sensory testing in preclinical models to enhance clinical translation.
