E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the safety and efficacy of ravagalimab vs placebo for the treatment of Primary Sjogren's Syndrome (pSS) in subjects with moderately to severely active Primary Sjogren's Syndrome (pSS). |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Adult male or female, between 18 and 75 years of age, inclusive, at time of the Screening. • Primary Sjogren’s syndrome (pSS) diagnosed according to the American College of Rheumatology (ACR)/EULAR 2016 Criteria. • Lymphocyte focus score (local lymphocytic infiltrates) ≥1 in sub labial salivary gland specimen. Subjects with biopsy obtained 24 months prior to Screening and meeting this criteriona will be eligible but must have a sub labial biopsy obtained at the Baseline Visit. Subjects without a prior sub labial biopsy within 24 months of Screening will obtain a biopsy for a lymphocyte focus score at Screening. • EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI) ≥5 at Screening and Baseline. • EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI) ≥ 6 at Screening and Baseline. |
|
E.4 | Principal exclusion criteria |
1) Female subject who is not pregnant, breastfeeding, or considering becoming pregnant during the study or for approximately 84 days.
2) Subjects must have discontinued all immunosuppressants (i.e., azathioprine , methotrexate (MTX), leflunomide (LEF), hydroxychloroquine (HCQ), chloroquine, sulfasalazine, mycophenolate mofetil, rituximab, other biologics, or JAK inhibitors), other than corticosteroids (equivalent to prednisone ≤ 10 mg/day), prior to the Baseline, with the following washout: • HCQ must be discontinued ≥ 6 months prior to Baseline • LEF must be discontinued ≥ 6 months prior to Baseline • 1 year for rituximab OR 6 months if B cells have returned to pretreatment level or normal reference range (local laboratory) if pretreatment levels are not available; • Discontinuation or modification of all other immunosuppressants must occur ≥ 4 weeks prior to Baseline or at least five times the mean terminal elimination half-life of the drug before undergoing the Baseline, whichever is longer.
3) Subject must not receive IV anti-infectives within 35 days prior to Baseline or oral/intramuscular (IM) anti-infectives within 14 days prior to the Baseline |
