Safety, Tolerability, and Pharmacokinetics of Andecaliximab in Adults With Chronic Obstructive Pulmonary Disease (COPD)

The primary objective of the study is to assess the safety and tolerability of multiple infusions of andecaliximab (formerly GS-5745) in participants with chronic obstructive pulmonary disease (COPD) as assessed by adverse events (AEs) and laboratory abnormalities.

* Male individuals and female individuals of childbearing potential who engage in heterosexual intercourse must agree to use protocol specified method(s) of contraception. Male individuals must refrain from sperm donation for 90 days post last infusion of the study drug
* Diagnosis of COPD per Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines for at least 6 months prior to screening and anticipated to remain on stable therapy for the duration of the study
* Post-bronchodilator forced expiratory volume in one second (FEV1) ≥ 40% predicted
* No changes in COPD medications within 30 days prior to randomization
* Hepatic panel \[aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, direct bilirubin, alkaline phosphatase, lactate dehydrogenase (LDH)\] ≤ 2 times the upper limit of the normal range (ULN)

Key Exclusion Criteria:

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

* 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
* Individuals currently on nonbiologic immune modulator medications such as: azathioprine, cyclosporine, hydroxychloroquine, leflunomide, methotrexate, mycophenolate mofetil, sulfasalazine, tofacitinib, within 90 days of randomization
