Conditions: Uveitis
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 58
Healthy volunteers: no

Brief summary:
Primary Objective:

To evaluate the efficacy of sarilumab at Week 16 in participants with non-infectious uveitis (NIU).

Secondary Objectives:

To evaluate the change in best corrected visual acuity (BCVA). To evaluate the safety of subcutaneous sarilumab in participants with NIU. To evaluate the change in macular edema. To evaluate the change in other signs of ocular inflammation. To evaluate the effect on retinal vessel leakage. To evaluate the effect of sarilumab on reducing concomitant immunosuppressant therapy.

To evaluate the change in ocular inflammation in the anterior chamber. To evaluate the pharmacokinetics of sarilumab in NIU participants. To evaluate the immunogenicity with anti-drug antibodies (ADA).

Detailed description:
The total duration per participant was up to 58 weeks, which included a 2 week screening period, 16 weeks principal treatment period (Part A), 34 weeks extension treatment period (Part B) or open label treatment period (Part C), and 6 weeks after last treatment administration.

Participants with decrease in vitreous haze (VH) ≥2; or corticosteroids dose \<10 mg/day at Week 16 were considered as responders. Participants who did not complete the principal treatment period (Part A) due to lack of efficacy; or no decrease in VH ≥2 and corticosteroids dose ≥10 mg/day at Week 16; or no decrease in VH ≥2 and corticosteroids dose missing at Week 16; or non-responder according to medical review, were considered as non-responders.

Responder participants, observed at Week 16 (at the end of Part A), were invited to continue in the extension treatment period (Part B).

Non-responder participants, observed within the first 16 weeks, were offered to be treated by open-label sarilumab (Part C).

Arms:
arm 1: Placebo (for Sarilumab) subcutaneous (SC) injection every 2 weeks (q2w) for 16 weeks during principal treatment period (Part A) with background therapy of Prednisone (or equivalent oral corticosteroid) ≥15 mg/day and \<80 mg/day as single therapy or in combination with Methotrexate (MTX) 10 to 25 mg/week and folic acid per local prescribing practice. Responders continued with the same treatment regimen up to Week 50 during extension treatment period (Part B) and non-responders were proposed to be treated with open-label Sarilumab 200 mg q2w in open-label treatment period (Part-C). arm 2: Sarilumab 200 mg SC injection q2w for 16 weeks during principal treatment period (Part A) with background therapy of Prednisone (or equivalent oral corticosteroid) ≥15 mg/day and \<80 mg/day as single therapy or in combination with MTX 10 to 25 mg/week and folic acid per local prescribing practice. Responders continued with the same treatment regimen up to Week 50 during extension treatment period (Part B) and non-responders were proposed to be treated with open-label Sarilumab 200 mg q2w in open-label treatment period (Part-C).
