OS was defined as the time interval from the date of randomization to death from any cause.
ORR was defined as the percentage of participants with confirmed overall best response of complete response (CR) or partial response (PR) after starting study drug but before starting any new chemotherapy or radiotherapy as assessed by the investigator according to Response Criteria in Solid Tumors (RECIST) version 1.1. CR was defined as the disappearance of all target lesions and disappearance of all non-target lesions and normalization of tumor marker level. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
This composite endpoint will measure the safety and tolerability profile of GS-5745.
This composite endpoint will measure the plasma PK profile of GS-5745. The following parameters will be measured, where applicable: * Cmax: maximum observed concentration of drug in plasma * AUClast: concentration of drug from time zero to the last quantifiable concentration * AUC0-inf: area under the plasma concentration versus time curve starting with time zero to infinity
A treatment-emergent laboratory abnormality was defined as an increase of at least 1 abnormality grade from baseline and occurring after the first dose of study drug and within 30 days after last study drug administration. The severity of laboratory abnormalities was assessed as Grade 0, 1 (mild), 2 (moderate), 3 (severe), or 4 (potentially life threatening) using the Common Terminology Criteria for Adverse Events (CTCAE), version 4.03. The most severe graded abnormality from all tests was counted for each participant.
The presence of anti-andecaliximab antibodies in serum samples was determined using an electrochemiluminescent (ECL) assay that detects antibodies that bind to andecaliximab.
Treatment-emergent laboratory abnormalities were defined as values that increase at least one toxicity grade from baseline. Participants with any laboratory abnormality were reported.
TEAEs are any AEs with an onset date of on or after the study drug start date and no later than 30 days after permanent discontinuation of study drug or any AEs leading to premature discontinuation of study drug.
Cmax is defined as the maximum concentration of drug.
Cmax is defined as the maximum concentration of drug over the dosing interval. Data for Day 1 was based on the data collected from Day 1 through Day 8. Data for Day 29 was based on the data collected from Day 29 through Day 36.
Ctau is defined as the observed drug concentration at the end of the dosing interval.
AUCinf is defined as the area under the plasma concentration versus time curve extrapolated to infinite time.
AUCtau is defined as the area under the plasma concentration versus time curve over the dosing interval. Data for Day 1 was based on the data collected from Day 1 through Day 8. Data for Day 29 was based on the data collected from Day 29 through Day 36.
AUClast is defined as the area under the plasma concentration versus time curve from time zero to the last observable concentration.

Andecaliximab is an investigational monoclonal antibody developed by Gilead Sciences, Inc. (ticker GILD). It has been studied in gastric adenocarcinoma, gastroesophageal junction adenocarcinoma, pancreatic cancer, ulcerative colitis, and chronic obstructive pulmonary disease. It is not an approved therapy and remains in clinical development.
Andecaliximab targets MMP9, also known as matrix metalloproteinase 9. It is an inhibitor of this enzyme, meaning the monoclonal antibody is designed to bind and block MMP9 activity. MMP9 inhibition is the mechanism explored across the inflammatory and oncology indications studied with this agent.
Andecaliximab is developed by Gilead Sciences, Inc., which trades under the ticker GILD. Gilead sponsored the clinical program evaluating the antibody in gastric and gastroesophageal junction adenocarcinoma, ulcerative colitis, and chronic obstructive pulmonary disease.
Andecaliximab is investigational and has been studied across Phase 1, Phase 2, and Phase 3 clinical trials. The program includes completed Phase 1 studies in ulcerative colitis and chronic obstructive pulmonary disease, a completed Phase 2 study in gastric adenocarcinoma, and a completed Phase 3 study in gastric adenocarcinoma.
Completed trials include NCT02545504, a Phase 3 study of andecaliximab with mFOLFOX6 as first line treatment for advanced gastric or gastroesophageal junction adenocarcinoma, and NCT02864381, a Phase 2 study combining andecaliximab with nivolumab in the same cancer types. NCT02077465 studied COPD and NCT01831427 studied ulcerative colitis.
Andecaliximab has been evaluated in gastric adenocarcinoma and gastroesophageal junction adenocarcinoma, including a Phase 3 trial with mFOLFOX6 as first line treatment and a Phase 2 trial combined with nivolumab. It is an investigational agent and is not an approved treatment for these cancers.
