Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Experiencing Treatment-Emergent Adverse Events |  | First dose date up to Day 29 plus 30 days | 
| Percentage of Participants Experiencing Treatment-Emergent Laboratory Abnormalities | A treatment-emergent laboratory abnormality was defined as an increase of at least 1 abnormality grade from baseline and occurring after the first dose of study drug and within 30 days after last study drug administration. The severity of laboratory abnormalities was assessed as Grade 0, 1 (mild), 2 (moderate), 3 (severe), or 4 (potentially life threatening) using the Common Terminology Criteria for Adverse Events (CTCAE), version 4.03. The most severe graded abnormality from all tests was counted for each participant. | First dose date up to Day 29 plus 30 days | 
| Percentage of Participants Who Developed Anti-andecaliximab Antibodies | The presence of anti-andecaliximab antibodies in serum samples was determined using an electrochemiluminescent (ECL) assay that detects antibodies that bind to andecaliximab. | Day 43 |
