On-demand anakinra for painful attacks in colchicine-resistant FMF patients who refuse daily injections

Randomized Controlled Trial in Patients on Long-term Colchicine With Colchicine-resistant Familial Mediterranean Fever (FMF) to Evaluate the Efficacy of On-demand Anakinra Treatment for Painful Attacks in Patients Who Refuse Continuous Daily Therapy

Phase 3 Interventional Assistance Publique - Hôpitaux de Paris · NCT06336733

This trial will test whether taking anakinra only when an FMF attack starts reduces pain and symptoms for people with colchicine-resistant FMF who refuse continuous anti‑IL‑1 therapy.

What this trial studies

This Phase 3 randomized prospective trial compares on‑demand subcutaneous anakinra (100 mg daily started at prodrome and continued until 24 hours after remission, up to 7 days) plus ongoing colchicine to standard symptomatic analgesic care with ongoing colchicine in colchicine‑resistant FMF patients who decline continuous anti‑IL‑1 therapy. Eligible participants are age 6 and older with confirmed FMF (Livneh criteria and two non‑ambiguous MEFV mutations) and persistent attacks despite maximal tolerated colchicine dose. Patients with active infection, active tuberculosis, recurrent serious infections, or ongoing biological inflammation between attacks are excluded. The study is sponsored by Assistance Publique - Hôpitaux de Paris and conducted at Hopital Tenon in Paris as a randomized interventional comparison of attack‑by‑attack management strategies.

Who should consider this trial

Good fit: Ideal candidates are people aged 6 or older with genetically confirmed FMF and colchicine resistance (≈≥1 attack/month over 3 months on maximum tolerated colchicine) who refuse daily anakinra but have full French ALD coverage and no ongoing inflammation between attacks.

Not a fit: Patients with persistent biological inflammation between attacks, active or recent serious infection, active tuberculosis, recurrent infections, or those who require continuous IL‑1 blockade (for example high amyloidosis risk) are unlikely to benefit from an on‑demand approach.

Why it matters

Potential benefit: If successful, on‑demand anakinra could relieve attack pain and disability for patients who refuse daily injections while reducing overall treatment burden and cost compared with continuous biologic therapy.

How similar studies have performed: Continuous anti‑IL‑1 therapies such as daily anakinra or intermittent canakinumab have shown clinical benefit in colchicine‑resistant FMF, but randomized evidence specifically testing an on‑demand anakinra approach is limited and this is the first randomized prospective comparison.
