Capsaicin patch compared to oral duloxetine for chemotherapy-induced nerve pain

Official title: Capsaicin 179 mg Patch Versus Oral Duloxetine in Patients With Chemotherapy-induced Peripheral Neuropathy : a Phase 3 Randomized Multicentric Open-label Study.

Run by Institut Cancerologie de l'Ouest · NCT05840562 · Data updated 2026-11-12

This study is testing whether a capsaicin patch or an oral medication called duloxetine works better to relieve nerve pain in cancer patients who have had chemotherapy.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 with painful CIPN symptoms persisting for at least one month after chemotherapy with taxanes or platinum salts.

Probably not a fit

Patients with known carcinomatous meningitis or those who have pre-existing neuropathies unrelated to chemotherapy may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of a capsaicin patch versus oral duloxetine in treating chemotherapy-induced peripheral neuropathy (CIPN), a painful condition affecting many cancer patients after neurotoxic chemotherapy. Participants will be patients experiencing painful symptoms such as numbness and tingling in a 'gloves and socks' distribution, with a pain score of 4 or higher. The study aims to determine which treatment provides better relief from CIPN symptoms, with a focus on those whose symptoms persist after chemotherapy. The trial is designed as a phase 3 interventional study to provide robust data on treatment efficacy.

Why it matters

Potential benefit: If successful, this study could offer a new effective treatment option for patients suffering from debilitating nerve pain due to chemotherapy.

How similar studies have gone: Previous studies have shown positive results for duloxetine in treating CIPN, but the use of a capsaicin patch in this context is a novel approach.
