Study Endpoints

Primary Endpoints

Overall Survival (OS)
Andecaliximab + mFOLFOX6 median follow-up at the time of final analysis: 19.43 months; Placebo + mFOLFOX6 median follow-up at the time of the final analysis: 19.45 months

OS was defined as the time interval from the date of randomization to death from any cause.

Objective Response Rate (ORR)
Up to 41 weeks

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.

Incidence of adverse events, changes in laboratory tests and vital signs from baseline, and development of immunogenicity after dosing
Up to 100 days

This composite endpoint will measure the safety and tolerability profile of GS-5745.

PK profile of GS-5745
Predose and postdose on Days 1 and Day 11, and Weeks 2, 3, 4, 6, and 8

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

Percentage of Participants Experiencing Treatment-Emergent Adverse Events
First dose date up to Day 29 plus 30 days
Percentage of Participants Experiencing Treatment-Emergent Laboratory Abnormalities
First dose date up to Day 29 plus 30 days

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.

Percentage of Participants Who Developed Anti-andecaliximab Antibodies
Day 43

The presence of anti-andecaliximab antibodies in serum samples was determined using an electrochemiluminescent (ECL) assay that detects antibodies that bind to andecaliximab.

Percentage of Participants Experiencing Laboratory Abnormalities
Part A: First dose date up to 32 weeks plus 30 days; Part B: First dose date up to 181 weeks plus 30 days

Treatment-emergent laboratory abnormalities were defined as values that increase at least one toxicity grade from baseline. Participants with any laboratory abnormality were reported.

Percentage of Participants Who Experienced Any Treatment-Emergent Adverse Events (TEAEs) (SAD/MAD)
SAD Cohorts: First dose date (Day 1) plus 30 days, MAD/Adaptive MAD Cohort: First dose date up to last dose date (Maximum: Day 29) plus 30 days

Frequently asked questions about GS-5745

What is GS-5745?

GS-5745 is an investigational small molecule being developed by Gilead Sciences, Inc. (ticker GILD) for immunology indications, specifically rheumatoid arthritis and ulcerative colitis. It has completed Phase 1 clinical testing and is not yet approved for any use.

What is GS-5745 used for in rheumatoid arthritis and ulcerative colitis?

GS-5745 is being studied as a potential treatment for rheumatoid arthritis and ulcerative colitis. Both are immune-mediated inflammatory conditions. The drug remains investigational and has only completed Phase 1 trials, so it is not available as a marketed therapy for either indication.

Who makes GS-5745?

GS-5745 is made by Gilead Sciences, Inc., which trades on the Nasdaq under the ticker GILD. Gilead is the developer responsible for the clinical program evaluating the drug in rheumatoid arthritis and ulcerative colitis.

What phase is GS-5745 in?

GS-5745 is in Phase 1 clinical development. It has completed Phase 1 testing in healthy volunteers and in patients with rheumatoid arthritis. No later-phase trials have been reported, and the drug is not approved for any indication.

What clinical trials is GS-5745 in?

GS-5745 has been evaluated in two completed Phase 1 trials. NCT02209987 assessed subcutaneous bioavailability, safety, and tolerability in 28 healthy adults in New Zealand. NCT02176876 evaluated safety, tolerability, and pharmacokinetics in 18 subjects with rheumatoid arthritis in Czechia and Hungary.

Is GS-5745 the same as GS-5745 SC?

Yes, GS-5745 SC is an alternative name for GS-5745. The SC designation refers to the subcutaneous formulation studied in the Phase 1 bioavailability trial NCT02209987. Both names refer to the same investigational small molecule developed by Gilead Sciences.
