Exclusion Criteria

•Clinically significant active infection as judged by the investigator during screening

•A positive QuantiFERON-TB GOLD test during screening
•History of malignancy within the last 5 years except for patients who have been treated locally for non-melanoma skin cancer or cervical carcinoma in situ
•Any serious cardiac event such as myocardial infarction, unstable or life-threatening arrhythmia, hospitalization for cardiac failure within 6 months prior to randomization or any significant or new electrocardiogram (ECG) finding at Visit 1 as judged by the Investigator
•A hospitalization for a respiratory event such as, but not limited to, COPD, pneumonia, bronchiolitis, within the previous 6 months prior to randomization
•Chronic lung disease other than COPD such as: asthma, cystic fibrosis or fibrotic disease, α-1-antitrypsin deficiency, interstitial lung disease, pulmonary thromboembolic disease, or bronchiectasis
•Chronic use of systemic corticosteroids and/or treatment with systemic corticosteroids for an acute exacerbation of COPD (AECOPD) event, or other medical condition not requiring hospitalization, within 90 days of randomization.
•Treatment with antibiotics for an AECOPD event, or other medical condition not requiring hospitalization within 90 days of randomization, or any minor medical event not requiring hospitalization within 14 days of randomization.
•Treatment with any marketed or investigational biologic within 5 half-lives of the molecule or if unknown within 90 days of screening

Outcomes

Primary Outcomes

Percentage of Participants Experiencing Treatment-Emergent Adverse Events

Time Frame: First dose date up to Day 29 plus 30 days

Percentage of Participants Experiencing Treatment-Emergent Laboratory Abnormalities

Time Frame: First dose date up to Day 29 plus 30 days

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.

Percentage of Participants Who Developed Anti-andecaliximab Antibodies

Time Frame: Day 43

The presence of anti-andecaliximab antibodies in serum samples was determined using an electrochemiluminescent (ECL) assay that detects antibodies that bind to andecaliximab.
