Run by Kiniksa Pharmaceuticals International, plc · NCT07010159 · Data updated 2026-11-12

This trial tests whether KPL-387 can control pain and inflammation and lower the chance of future attacks in people having an acute episode of recurrent pericarditis despite standard treatment.

Is this trial a fit for you?

Likely a good fit

People who weigh at least 40 kg with documented recurrent pericarditis who are currently experiencing an acute flare despite treatment with NSAIDs and/or colchicine (and possibly glucocorticoids in Phase 3) and who can attend visits at a participating U.S. site would be typical candidates.

Probably not a fit

Patients whose pericarditis is due to specific excluded causes, those with active or untreated latent tuberculosis, immunodeficiency or immunosuppression, recent or planned use of other investigational drugs, or who cannot attend required site visits are unlikely to benefit from or be eligible for this protocol.

What this trial studies

This phase 2/3 interventional trial enrolls participants with recurrent pericarditis who are experiencing an acute flare and assigns them to KPL-387 or placebo to determine the best dose and confirm effectiveness. Phase 2 compares different dosing regimens to identify the regimen taken forward, Phase 3 confirms efficacy for symptom control and reduction in recurrence risk, and an optional long-term extension follows participants to monitor durability of disease control. Safety, tolerability, blood drug concentrations, and blood markers of immune activity are measured throughout. Background therapy such as NSAIDs and colchicine (and glucocorticoids in Phase 3) is permitted per the protocol.

Why it matters

Potential benefit: If successful, KPL-387 could reduce pain and inflammation during flares and decrease how often recurrent pericarditis returns, potentially reducing reliance on long-term steroids or repeated treatments.

How similar studies have gone: Other biologic anti-inflammatory therapies have shown benefit in reducing symptoms and recurrences in prior recurrent pericarditis trials, so this approach has clinical precedent.
