About this trial

The objective of this multicentric, randomized controlled double-blind clinical trial is to demonstrate the efficacy of transdermal application of capsaicin in patients with painful digital osteoarthritis with a neuropathic pain component.

Participants will receive either a transdermal patch of capsaicin 179 mg (8%) or the control treatment (capsaicin 0.04%).

Researchers will compare the intensity of pain in the fingers at day 60 in the capsaicin 8% group versus capsaicin 0.04% (control arm)
