Brief summary: Rheumatoid arthritis (RA) is a frequent and disabling disease, requiring early management to achieve clinical remission. Recently, baricitinib (jak1-jak2 inhibitor) has been shown to as an efficient treatment in placebo-controlled trials, and compared to the reference treatment with TNF inhibitor (adalimumab). Its efficacy has been reported on the inflammatory parameters, but more importantly on patient-reported outcomes. Baricitinib is thought to have anti-inflammatory effects, via its inhibition of the JAK pathway. Importantly, it has also been suggested to affect mood and pain.

Hypotheses: Inhibition of JAK Kinase pathway in patients with RA will improve emotional and cognitive processing involved in mood disorders and decrease pain sensitization.

The primary objective of this study is to evaluate early emotional impact of the JAK 1/2 inhibitor Baricitinib assessed by a facial emotion recognition task. This precocious effect on emotion processing is a surrogate marker of clinical imporvement in mood.

Phase 4 study, Double-blind randomized control study with patients receiving placebo or baricitinib for 7 days, then open label study until day 42 with all patients receiving baricitinib during 5 weeks.

Detailed description: Rheumatoid arthritis (RA) is a frequent and disabling disease, requiring early management to achieve clinical remission. Recently, baricitinib (jak1-jak2 inhibitor) has demonstrated its efficacy compared to placebo, and compared to the reference treatment with TNF inhibitor (adalimumab). Its efficacy has been reported on the inflammatory parameters but more importantly on patient reported outcomes. Inhibition of JAK pathway could have anti-inflammatory activity but also direct action on mood and pain.

Hypotheses: Inhibition of JAK Kinase pathway in patients with RA will improve emotional and cognitive processing involved in mood disorders and decrease pain sensitization.

The primary objective of this study is to evaluate early emotional impact of the JAK 1/2 inhibitor Baricitinib assessed by Harmer's cognitive and emotional battery, This emotional aspect is a surrogate marker of future mood impact.

The primary outcome is the number of accurate responses in facial emotion recognition task at day 1 using Harmer's cognitive battery (based on Harmer \& Cowen evaluation protocol at day 1).

Phase 4 study,Double-blind randomized control study with patients receiving placebo or baricitinib for 7 days, then open label study until day 42 with all patients receiving baricitinib during 5 weeks. At baseline (day 0), RA activity, mood symptoms, the number of accurate responses in facial emotion recognition task (Harmer's cognitive battery), clinical pain sensitization, will be assessed.3 follow-up research visits will be conducted at day 1, 8 and 42 (final visit) at the Pitié Salpêtrière hospital.The first intake of the Investigational medicinal product (IMP) (baricitinib or placebo) is at day 1. At day 1, the number of accurate responses in facial emotion recognition task and RA activity will be evaluated (2 to 4 hours after intake of baricitinib). At day 8 and 42, RA activity and flares, mood symptoms, the number of accurate responses in facial emotion recognition task (Harmer's cognitive battery), clinical pain sensitization, will be assessed. In each group (placebo vs Baricitinib), 20 patients will underwent a non-contrast MRI at day 0 and 8 (with evaluation of mood modification using BOLD signal during the different experimental conditions of the Cyberball task with comparison to baseline condition, and pain evaluation using fMRI-based neurological pain signature provided by Wager et al.) During the follow-up until day 42, patients will conduct questionnaires (day 15 and 29) at home about RA activity, pain (Patient pain VAS, Patient global assessment of the disease, Flare RA questionnaire) and psychometric questionnaire (Hospital Anxiety and Depression Scale)
