| NCT02334306 | A Phase 2a, Randomized, Placebo Controlled, Study to Evaluate the Safety and Efficacy of AMG 557/MEDI5872 in Primary Sjögren's Syndrome | PHASE2 | COMPLETED | 32 | — | — | Jun 8, 2015 | Aug 13, 2018 | Mar 19, 2019 | 13 | United States, France +2 |
The European League Against Rheumatism Sjogren's Syndrome Disease Activity Index (ESSDAI) is a clinical index that measures Sjogren's syndrome disease activity. A physician scores the disease activity level of 12 organ-specific domains (constitutional, lymphadenopathy, articular, muscular, cutaneous, glandular, pulmonary, renal, peripheral nervous system, central nervous system, hematological, and biological). Each domain is assessed for activity level in 3 or 4 levels (i.e., no, low, moderate, high) according to their severity (no disease activity equals to 0 and for high disease activity the domain score equals 3 or 4). Each domain is assigned a weight between 1 and 6, and the domain score is multiplied by the domain weight. Overall score is calculated as sum of all individual weighted domain scores (ranges from 0 (best) to 123 (worst activity). A higher score indicates worsening of the disease. Adjusted mean change and standard error are presented.

| MEDI5872 210 mg | EXPERIMENTAL | Participants will receive a fixed SC dose of 210 mg MEDI5872 every week (QW) from Days 1 to 15 and then every 2 weeks (Q2W) from Days 29 to 85 in double-blind period. In open-label period, participants will continue dosing of MEDI5872 210mg Q2W from Days 99 to 183 and will receive an additional dose of blinded placebo on Day 106. |
| Placebo/MEDI5872 210 mg | PLACEBO_COMPARATOR | Participants will receive a SC dose of placebo matching with MEDI5872 QW on Days 1, 8, and 15 and then Q2W from Days 29 to 85 in double-blind period. In open-label period, participants will receive a fixed SC dose of 210 mg MEDI5872 QW (Days 99 to 113) and Q2W (Days 127 to 183) in open-label period. |

| AMG 557/MEDI5872 | BIOLOGICAL | Participants will receive a fixed SC dose of 210 mg MEDI5872 (AMG 557/MEDI5872) QW for 3 weeks (Days 1 to 15) and then Q2W for 9 weeks (Days 29 to 85) in double-blind period of the study. In open-label period, all participants from double-blind period will receive a fixed SC dose of 210 mg MEDI5872 from Day 99 to Day 183 (QW from Days 99 to 113 for participants from Placebo arm and on Days 99 and 113 for participants from MEDI5872 210 mg arm; and Q2W from Days 127 to 183 for participants from both arms). |
| Placebo | OTHER | The SC dose of placebo every week for 3 weeks (Days 1 to 15) and then every 2 weeks for 9 weeks (Days 29 to 85) in double-blind period of the study. In open-label period, an additional dose of blinded placebo will be administered on Day 106 for participants who will receive MEDI5872 210mg in double-blinded period. |
