E.3 | Principal inclusion criteria |
1. Age ≥18 years at the time of signing informed consent.

manual [SRM]) with a duration of RA disease of ≥6 months at time of
screening and participant not diagnosed before 16 years of age.
3. Must have active disease at both screening and baseline, as defined by
having both:
a. ≥6/68 tender/painful joints (TJC), and
b. ≥6/66 swollen joints (SJC).
If surgical treatment of a joint has been performed, that joint cannot be
counted in the TJC or SJC for enrolment purposes
4. Must have a high sensitivity C-reactive protein (hsCRP) measurement
≥3 mg/L at screening.
5. Must meet Class I, II or III of the ACR 1991 Revised Criteria for Global
Functional Status in RA (see SRM).
6. Must have inadequate response despite currently taking at least one
and at most two concomitant csDMARDs for at least 12 weeks prior to
Day 1, from the following:
a. Methotrexate (MTX): weekly 15-25 mg oral or injected, for at least 12
weeks at the maximum tolerated dose prior to Day 1, with no change in
route of administration in this time. A lower dose of ≥7.5 mg/week is
acceptable if reduced for reasons of intolerance to MTX, e.g.
nausea/vomiting, hepatic or hematologic toxicity, or per local
requirement (there must be clear documentation in the medical record).
Exception: A lower dose of 6 mg/week is allowed if the minimum locally
approved or recommended dose is lower than 7.5 mg/week.
b. Hydroxychloroquine up to 400 mg/day or chloroquine up to 250
mg/day.
c. Sulfasalazine up to 3000 mg/day.
d. Leflunomide up to 20 mg/day. Note: concomitant use of leflunomide
and methotrexate is not allowed, for safety reasons.
e. Bucillamine up to 100 mg/day (or up to 300 mg/day if permitted per
local requirements).
f. Iguratimod up to 50 mg/day.
g. Tacrolimus up to 3 mg/day.
NOTE: The dose of csDMARD(s) must be stable and tolerated for at least
8 weeks prior to Day 1 and should remain stable throughout the study
from screening to end of treatment period, except adjustment for safety
reasons.
7. Must have inadequate response to at least one biologic DMARD at an
approved dose and/or at least one JAK inhibitor (JAKi) at an approved
dose. In both cases this may be with or without combination with a
csDMARD. Prior bDMARD or JAKi therapy must be discontinued before
randomisation.
8. Body weight ≥40 kg
9. Male or female participants are eligible to participate so long as they
meet the contraceptive eligibility criteria and agree to abide by the
contraceptive requirements.
10. Capable of giving signed informed consent which includes
compliance with the requirements and restrictions listed in the informed
consent form (ICF) and in this protocol.
11. For participants on MTX: must be willing to continue or initiate
treatment at screening, with oral folic acid (at least 5 mg/week) or
equivalent and be treated during the entire study (mandatory comedication
for MTX treatment). |

E.4 | Principal exclusion criteria |
1. Active infections (including localised infections), or history of recurrent infections (excluding recurrent fungal infections of the nail
bed), or has required management of acute or chronic infections, as described in the protocol
2. Symptomatic herpes zoster within 3 months prior to screening
3. Hereditary or acquired immunodeficiency disorder, including immunoglobulin deficiency.
4. Known infection with human immunodeficiency virus (HIV) or positive test at screening.
5. History of infected joint prosthesis at any time, with the prosthesisstill in situ. History of chronic leg ulcers, permanent in-dwelling catheters, chronic sinusitis, recurrent chest infections or recurrent urinary tract infections. 6. Any baseline symptomatology that in the investigator's opinion would confound the early detection of pulmonary alveolar proteinosis based upon clinical features, such as persistent cough (CTC grade ≥2) or persistent dyspnoea (dyspnoea scale Grade ≥2).
7. Current unstable liver or biliary disease per investigator assessment defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminaemia, oesophageal or gastric varices, persistent jaundice, or cirrhosis.
8. Current acute or chronic Hepatitis B and/or Hepatitis C.
9. Current or history of renal disease or estimated glomerular filtration rate (eGFR) by Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI) calculation <30 mL/min/1.73m2 at screening.
10. Breast cancer within the past 10 years or lymphoma, leukaemia, or any other malignancy within the past 5 years except for cervical
carcinoma in situ that has been resected with no evidence of recurrence or metastatic disease, or basal cell or squamous epithelial cancers of the
skin that have been resected with no evidence of recurrence or metastatic disease for at least 3 years.
11. History of any lymphoproliferative disorder, such as Epstein Barr Virus (EBV) related lymphoproliferative disorder, or signs and symptoms suggestive of current lymphatic disease.
12. History or presence of significant other concomitant illness according to the Investigator judgment such as, but not limited to cardiovascular
(including Stage III or IV cardiac failure according to New York Heart Association classification, myocardial infarction within 3 months, unstable angina pectoris, uncontrolled hypertension, uncontrolled hypercholesterolemia), neurological, endocrinological, gastrointestinal
(including diverticulitis), hepatic disease, metabolic, lymphatic disease, or previous renal transplant that would adversely affect the participant's
participation
13. Any condition or contraindication as addressed in the local product information or local clinical practice for sarilumab that would preclude the participant from participating in this protocol.
14. History of other inflammatory rheumatologic or systemic autoimmune disorder, other than Sjögren's syndrome secondary to RA, that may confound the evaluation of the effect of the investigational
product such as mixed connective tissue disease, psoriatic arthritis, juvenile chronic arthritis, spondyloarthritis, Felty's Syndrome, systemic
lupus erythematosus, scleroderma, Crohn's disease, ulcerative colitis, or vasculitis.
15. Presence of fibromyalgia that, in the investigator's opinion, would make it difficult to appropriately assess RA activity in this study.
16. Undergone any major surgery within 8 weeks prior to study entry or will require major surgery during the study that, in the opinion of the investigator in consultation with the medical monitor, would pose an unacceptable risk to the participant.
17. Current or previous active Mycobacterium tuberculosis (TB) regardless of treatment.
18. Evidence of latent TB (as documented by a positive QuantiFERON-TB Gold plus test or T-SPOT.TB test at screening, no findings on medical history or clinical examination consistent with active TB, and a normal chest radiograph) except for participants that either:
- Are willing to complete at least 4 weeks of anti-TB therapy as per WHO
or national guidelines prior to randomisation and agree to complete the
remainder of treatment while in the study OR
- Are documented as having evidence of satisfactory anti-TB treatment
as per WHO or national guidelines within the last 5 years following
review by a physician specialising in TB.

receive satisfactory anti-tuberculosis treatment as per WHO or national
guidelines. 20. Significant allergies to humanised monoclonal antibodies or known hypersensitivity to sarilumab or any of its inactive ingredients.
