Tofacitinib plus acitretin versus acitretin alone for primary cutaneous amyloidosis
Official title: A Prospective Cohort Study on the Efficacy and Safety Comparison of Tofacitinib Citrate Tablets Combined With Acitretin Capsules Versus Acitretin Capsules Alone in the Treatment of Primary Cutaneous Amyloidosis
Run by Army Medical University, China · NCT06998875 · Data updated 2026-11-12
This tests whether adding tofacitinib to acitretin helps adults with primary cutaneous amyloidosis and relieves itch faster than acitretin alone.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older with a clinical outpatient diagnosis of primary cutaneous amyloidosis (macular or lichen type) who can attend regular visits and have adequate medical records are ideal candidates.
✕Probably not a fit
Patients with nodular or systemic amyloidosis, those using other immunosuppressants/biologics, or those with incomplete records or major uncontrolled comorbidities are unlikely to benefit from joining this protocol.
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 Phase 4, prospective interventional cohort comparing combination therapy (tofacitinib plus acitretin) with acitretin alone in adults with primary cutaneous amyloidosis. Participants receive either the combination or acitretin monotherapy and are followed with regular outpatient visits to measure pruritus scores and monitor adverse events. The trial excludes nodular or systemic amyloidosis and concurrent use of other immunosuppressants or biologics, and requires reasonably complete prior medical records. The primary outcomes focus on speed and degree of itch relief and safety/tolerability of the combination regimen at a single dermatology center in Chongqing, China.
Why it matters
Potential benefit: If successful, the combination could reduce itch faster and improve symptom control for people with primary cutaneous amyloidosis without unacceptable side effects.
How similar studies have gone: There are limited case reports and small series suggesting JAK inhibitors can help pruritic skin diseases, but combining tofacitinib with acitretin for primary cutaneous amyloidosis is relatively novel and not well established.
