Open-label, Long-term Safety Study of Secukinumab in Polymyalgia Rheumatica (PMR)

The study will consist of an up to 4-week screening period, an up to 2-year Treatment Period which includes two Treatment Periods, and a 16-week treatment-free follow-up period (20 weeks post last dose of secukinumab).

Treatment period:

There will be two Treatment Periods (TPs): TP1 will be from the first dose administration of secukinumab (Baseline) to Week 24, where visits will occur every 4 weeks, and TP2 will be from post Week 24 visit (post-dose) to up to 2 years. Participants will return to the study site every 4 weeks from Baseline until Week 24 (Weeks 16 and 20 visits are optional on-site visits and needed when participants are unwilling/uncomfortable to self-administer study treatment at home/offsite), then every 12 weeks afterwards in TP2 for resupply of study medication but may return earlier if needed (i.e., those participants who are unwilling/uncomfortable to self-administer study treatment can continue to visit site every 4 weeks for drug administration if they wish to do so).

Follow-up period: An EoS visit (20 weeks after last administration of secukinumab) will be done for all participants, regardless of whether they complete the entire study as planned, or they discontinue prematurely.
