Brief Summary

Polymyalgia rheumatic (PMR) is an inflammatory rheumatic disease affecting the elderly. The diagnosis is based on established ACR/EULAR classification criteria. The activity of the disease is evaluated using the PMR-AS, a disease activity score based on morning stiffness, ability to elevate the upper limbs, physician's global disease assessment and pain assessment measured by the patient using VAS, and the C-reactive protein (CRP) level. The PMR-AS-CRP (PMR-AS) is considered as relevant to define disease activity (low activity \<7; moderate activity 7 to 17; high activity \>17), flare (\>10), remission (\<1.5), but also to decide if treatment has to be decreased, unchanged or increased (PMR-AS \<10: decrease, PMR-AS \>20 increase, 10≤ PMR-AS ≤20: stable dose) \[10-12\]. Long term low-dose glucocorticoid (GCs) (prednisone or prednisolone started at 12.5 to 25 mg/day progressively tapered) is the mainstay of the treatment. But comorbidities in PMR are due to GCs and 30% of the patients underwent a relapse when tapering GCs. Today, the physicians do not know what is the best duration and the best dosage of GCs. The international recommendation suggests to start prednisone at a dose between 12.5 to 25 mg, to be at 10 mg at 1 or 2 months, and then to decrease slowly. The treatment is generally ordered for 6-18 months but it is possible to try a shorter treatment duration when patients have been previously treated with GCs or in case of comorbidities. The TENOR study, a phase 2 study, demonstrated efficacy of tocilizumab as first line treatment in PMR and its ability to spare GCs. The Semaphore study confirmed the usefulness of tocilizumab in corticodependent forms and demonstrated its efficacy. Another IL-6 inhibitor, sarilumab was authorized for the treatment for polymyalgia rheumatic in adult patients with inadequate response to corticosteroid or relapsing disease but is not reimbursed in France. Baricitinib is an oral selective JAK inhibitor of JAK1 and JAK2 with a short half-life. There are two dosages available (i.e., 2-mg and 4-mg) which can help conduct a simple dose tapering. Administration of baricitinib resulted in a rapid dose dependent inhibition of IL-6 induced STAT3 phosphorylation. An evaluation could be made using the PMR-AS with and without imputation to minimize the effect of baricitinib on CRP by anti-IL-6 effect. Preliminary results of the BACHELOR study (34 patients treated with baricitinib or placebo) suggested a great efficacy of baricitinib in early PMR without steroids. It could be a treatment of PMR, with low dose or no steroids only during the first month, to minimize the adverse events of steroids. JAK inhibitors have been reevaluated by EMA, the Oral Surveillance study suggesting that tofacitinib (Xeljanz®) increases the risk of major cardiovascular problems, cancer, VTE, serious infections and death due to any cause when compared with medicines belonging to the class of TNF-alpha inhibitors. EMA has concluded that these safety findings apply to all approved uses of JAK inhibitors in chronic inflammatory disorders. Nevertheless, the risk was not increased during the first months of treatment in all studies and a short treatment could have lower risks than steroids. As no suitable treatment alternatives are available, excepted GCs which increase the vascular risk and osteoporosis, short treatment by jak inhibitor could be a relevant alternative treatment of PMR. Indeed, the physicians do not have any disease modifying drug (excepted anti IL6 off-label) in treatment of PMR. So, GCs are used for more than one year in the treatment of PMR. Baricitinib, used only 6 months demonstrated its ability to cure early PMR without steroids. It could be an alternative to steroid when physicians consider that ratio benefit/risk is better with a 6 months treatment by baricitininib than \>one year by steroids. Our goal is now to demonstrate in a large cohort the ability of a 6-month treatment with baricitinib in comparison to placebo to decrease glucocorticoids and then to maintain low disease activity without corticosteroids in PMR and a good safety profile. Due to the possible lower risk of 2 mg than 4 mg of baricitinib, but probably a lower efficacy, the investigators plan to compare both baricitinib (4 mg and 2 mg) to placebo. The study will be conducted in France.

Outcome Measures

Primary Outcomes (1)

  • Following of the Polymyalgia Rheumatica Activity score

    Polymyalgia Rheumatica Activity Score (PMR-AS) ≤10 (no flare) without steroids at week 24. The Polymyalgia Rheumatica Activity Score is calculated by combining several parameters (patient's pain assessment (using a visual analogue scale) + physician's global assessment of the disease (using a visual analogue scale)+ morning stiffness + C-Reactive Protein level). If PMR-AS ≤ 1,5 means remission of the disease. If PMR-AS \< 7 means inactive activity of the disease. If 7 \<PMR-AS \< 17 means low activity of the disease. If PMR-AS \> 17 means high activity of the disease.

    From week 0 to week 24
