Is this trial a fit for you?

Likely a good fit

Adults with coccygodynia who received a topical Capsaicin 8% patch between August 2016 and August 2022 at the participating institution.

Probably not a fit

Patients whose coccygodynia is driven predominantly by non-neuropathic mechanisms or who do not respond to topical capsaicin may not experience meaningful benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a retrospective, non-interventional study using anonymized patient data collected over six years to evaluate the analgesic effect of the Capsaicin 8% patch (QUTENZA) on coccygodynia. It also explores neuropathic factors that might predict response to treatment. The analysis focuses on real-world use in a French hospital setting, where first-line therapies are often insufficient and alternatives are limited. Outcomes of interest include changes in pain levels and potential neuropathic determinants of response. The study is conducted at Nantes University Hospital with data from CHU de Nantes and does not involve a prospective intervention beyond usual care.

Why it matters

Potential benefit: If successful, the patch could offer a targeted option to reduce coccyx pain for patients who have not responded to conventional therapies.

How similar studies have gone: There is limited prior research on real-world analgesic efficacy of Capsaicin 8% patches for coccygodynia; this observational work addresses a gap and may build on related neuropathic pain findings.
