Recruiting PHASE2 Neuropathic Pain

New treatment option for Neuropathic Pain

Official title Crisugabalin for Radiotherapy-Related Neuropathic Pain

ClinicalTrials.gov ID: NCT06766916

What this study is testing

What is Crisugabalin?

Crisugabalin is an investigational medicine, given as an once-daily pill taken by mouth, being studied as a potential treatment for neuropathic pain.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The purpose of this study is to evaluate whether Crisugabalin has similar efficacy compared to Pregabalin in reducing radiotherapy-related neuropathic pain (RRNP) in patients with head and neck cancers.
  • Phase 2: a mid-size study of how well it works
  • Which group you join is decided by chance.
