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.

Condition Intervention Phase
Chronic Obstructive Pulmonary Disease
Drug: GS-5745
Drug: Placebo to match GS-5745
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)

Further study details as provided by Gilead Sciences:

Primary Outcome Measures:
  • 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:
  • 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

  • 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

Enrollment: 11

Inclusion Criteria:

  • Weight: ≥ 45 kg to < 120 kg at screening
  • Males or non-pregnant, non-lactating females
  • Male subjects and female subjects of childbearing potential who engage in heterosexual intercourse must agree to use protocol specified method(s) of contraception. Male subjects 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)

Exclusion Criteria:

  • Clinically significant active infection as judged by the investigator during screening
  • Known history of HIV, hepatitis B or C during screening. Subjects who are hepatitis B surface antigen positive, but who received a successful series of hepatitis B vaccinations and never had the disease remain eligible
  • 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
  • Subjects currently on nonbiologic immune modulator medications such as: azathioprine, cyclosporine, hydroxychloroquine, leflunomide, methotrexate, mycophenolate mofetil, sulfasalazine, tofacitinib, within 90 days of randomization
