Summary
The primary objectives of this study are as follows:
* To assess the safety and tolerability of escalating single and multiple doses of GS-5745 (andecaliximab) in participants with moderate to severe ulcerative colitis (UC) as assessed by adverse events (AEs) and laboratory abnormalities
* To assess the pharmacokinetics (PK) of GS-5745 (andecaliximab) in participants with moderate to severe UC.
Eligibility Criteria
Key Inclusion Criteria
- Male or Female, 18 to 65 years of age
- Negative pregnancy test at screening
- Documented diagnosis of UC with a minimum disease extent of 15 centimeters (cm) from the anal verge
- Mayo Score of at least 3 for the SAD cohort and Mayo Score of at least 6 for the MAD cohorts

- Platelets ≥ 100 x 10^9/L.
Key Exclusion Criteria
- Pregnant or lactating females
- Exhibit severe UC/ clinically significant active infection
- Current use of oral corticosteroids at a dose equivalent to > 20 mg/day of prednisone
- Any dose adjustment in oral corticosteroids or oral immunosuppressants (6-MP, Azathioprine), or oral 5-aminosalicylate (5-ASA) compounds within 30 days of Baseline
- Use of rectal formulations of 5-ASA compounds or corticosteroids within 2 weeks prior to randomization
- Crohn's disease or indeterminate colitis

- Stool sample positive for Clostridium difficile (C. difficile) toxin, E. coli, Salmonella, Shigella, Campylobacter or Yersinia
- Treatment with Infliximab, Adalimumab, Natalizumab, Golimumab, Vedolizumab or Certolizumab within 8 weeks of randomization
- Any chronic medical condition (including, but not limited to, cardiac or pulmonary disease) that, in the opinion of the Investigator, would make the individual unsuitable for the study or would prevent compliance with the study protocol.
