Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to evaluate the effect of andecaliximab (GS-5745) on pre-bronchodilator forced expiratory volume in 1 second (FEV1) % predicted in adults with cystic fibrosis (CF) after 8 weeks of treatment.

There will be 2 parts to this study. In Part 1, andecaliximab 600 mg or placebo will be administered for 8 weeks. In Part 2, andecaliximab 300 mg, 150 mg, or placebo will be administered for 8 weeks. Part 2 will be initiated after completion of Part 1.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Confirmed diagnosis of CF as determined by the 2008 Cystic Fibrosis Foundation Consensus Report criteria
* Must have a body weight of \> 40 kg (88.2 lb) at study screening
* Pre-bronchodilator FEV1 ≥ 40% and ≤ 80% of predicted at screening
* Two pre-bronchodilator spirometry measures during screening and baseline must meet the following 2 criteria:

* The relative difference of FEV1(L), calculated as the absolute value of \[(first FEV1 - second FEV1) / first FEV1\] x 100 should be \< 12% AND
* The absolute difference in FEV1 should be \< 200 ml
* Negative Sputum Investigation/History of any Mycobacterium spp. or Burkholderia spp. per specified protocol-defined time periods
* Clinically stable with no evidence of significant respiratory symptoms that would require administration of IV antibiotics, oxygen supplementation, or hospitalization within 30 days of baseline.
* On stable CF chronic medical regimen for at least 30 days prior to baseline and expected to remain stable through the completion of the study. This includes but is not limited to: chronic azithromycin use, inhaled bronchodilators, inhaled corticosteroids, inhaled dornase alpha, inhaled hypertonic saline, inhaled mannitol, ivacaftor, and/or ivacaftor/lumacaftor.

Exclusion Criteria

* Concurrent use of oral antibiotics (excluding chronic azithromycin use) or IV antibiotics within 30 days of baseline. Prophylactic and chronic doxycycline use is prohibited during the study.
* Hospitalization for a respiratory event within 30 days of baseline
* Current use of systemic immunosuppressive drugs including oral corticosteroids within 30 days of Baseline
* Current requirement for daily continuous oxygen supplementation or requirement (medically necessary) of more than 2 L/minute at night (subject would not meet this exclusion criterion if supplemental oxygen is used for comfort only)
* History of solid organ (including lung) or hematologic transplant, or currently on a transplant waiting list
