Summary
This trial is testing the effects of the study drug on neuropathic pain caused by chemotherapy. It will last 13 weeks and participants will be randomly assigned to either the study drug or placebo group.
Who is the study for?
Adults aged 21+ with moderate to severe nerve pain due to chemotherapy (platinum/taxane) for at least 3 months, who are not currently undergoing treatment for cancer progression. Participants must be able to avoid pregnancy and complete questionnaires in English or the local language.
What is being tested?
The trial is testing Tetrodotoxin's effectiveness against neuropathic pain from chemotherapy compared to a placebo. It includes a screening period, two weeks of baseline pain assessment, a four-day treatment phase, and follows up for twelve weeks.
What are the potential side effects?
Potential side effects may include numbness or tingling sensations, nausea, headache, weakness or dizziness. Since Tetrodotoxin affects nerve function, it could potentially cause changes in sensation or motor skills.
