Brief Summary:
This study is to assess the safety, tolerability, and pharmacokinetics (PK) of multiple infusions of GS-5745 in participants with chronic obstructive pulmonary disease (COPD) as assessed by adverse events (AEs) and laboratory abnormalities.

Arm Intervention/treatment
Experimental: GS-5745
Participants will receive GS-5745 every 2 weeks for a total of 3 infusions.
Drug: GS-5745
400 mg GS-5745 administered intravenously

Placebo Comparator: Placebo to match GS-5745
Participants will receive placebo to match GS-5745 every 2 weeks for a total of 3 infusions.
Drug: Placebo to match GS-5745
Placebo to match GS-5745 administered intravenously

Primary Outcome Measures :
  1. Incidence of adverse events, change from screening in laboratory tests and vital signs, and development of immunogenicity after dosing [ Time Frame: Baseline to Day 29 plus 30 days ]
    This composite endpoint will measure the safety and tolerability profile of GS-5745.

Secondary Outcome Measures :
  1. PK parameters of GS-5745 as measured by AUC and Cmax [ Time Frame: Baseline to Day 29 ]
    • AUC represents the total amount of drug absorbed by the body by comparing plasma concentration over time
    • Cmax is defined as the maximum concentration of drug

  2. PK parameters of GS-5745 as measured by Tmax, Clast, Tlast, Ctau, λz, CL, and Vz [ Time Frame: Baseline to Day 29 ]
    • Tmax is defined as the time of Cmax
    • Clast is defined as the last observable concentration of drug
    • Tlast is defined as the time of Clast
    • Ctau is defined as the observed drug concentration at the end of the dosing interval
    • λz is defined as the terminal elimination rate constant
    • CL is defined as systemic clearance following intravenous (IV) administration
    • Vz is defined as apparent volume of distribution following IV administration
