Safety profile
Safety and tolerability data reflect exposure to ARCALYST in more than 2000 patients.1
These included patients with cryopyrin-associated periodic syndromes (CAPS) and recurrent pericarditis, patients with other diseases, and healthy volunteers.
- Included approximately 151 patients exposed for at least 6 months1
- Included 111 patients exposed for at least 1 year1
In the Phase 3 trial, RHAPSODY, injection-site reactions* and upper respiratory tract infections were the most common adverse events associated with use of ARCALYST.2


*Including erythema, swelling, pruritus, mass, bruising, inflammation, pain, edema, dermatitis, discomfort, urticaria, vesicles, warmth and hemorrhage.1
†Patients with multiple events were counted once in each appropriate category.
‡Counted once, according to the maximum severity of the adverse event.
§Cancer was an event of special interest.

DURATION OF TREATMENT
The duration of a patient's ARCALYST treatment will be determined by the prescribing physician.

Real-world evidence indicates that the mean duration of recurrent pericarditis could be up to 3 to 4 years from the first episode—longer in patients with a greater burden of recurrences3
- In RHAPSODY, the mean duration of disease at study entry was 2.4 years1
In RHAPSODY, the median duration of rilonacept treatment was 9 months2
- At the completion of the RW period, 74 of 75 eligible patients chose to enroll in the ongoing long-term extension (LTE) treatment period.2
At the 1-year anniversary of the start of the LTE treatment period, the median duration of continuous rilonacept therapy was approximately 20 months4
