ArmTypeDescription
Part 1: Arm A: DEN (Dose A) and NIVOEXPERIMENTALParticipants will receive DEN Dose A as an IV infusion in combination with NIVO as an IV infusion.
Part 1: Arm B: DEN (Dose B) and NIVOEXPERIMENTALParticipants will receive DEN Dose B as an IV infusion in combination with NIVO as an IV infusion.
Part 1: Arm C: DEN (Dose B)EXPERIMENTALParticipants will receive DEN Dose B as an IV infusion.
Part 2: Arm D: Safety Run-in (SRI) CohortEXPERIMENTALParticipants will receive DEN in combination with ramucirumab (RAM) and paclitaxel (PAC). If dose for DEN is deemed safe during the SRI Cohort, the study will move forward into the Expansion Period.
Part 2: Arm D: Expansion CohortEXPERIMENTALIf DEN dose is deemed safe in Arm D: SRI Cohort, participants will receive DEN at recommended dose as an IV infusion in combination with RAM and PAC.
DEN monotherapy (Arm A)EXPERIMENTALParticipants will receive DEN via intravenous (IV) infusion.
DEN in combination with NIVO (Arm B)EXPERIMENTALParticipants will receive DEN as an IV infusion in combination with NIVO as an IV infusion.
DEN in combination with Trifluridine-Tipiracil (FTD-TPI) and BVZ (Arm C)EXPERIMENTALParticipants will receive DEN as an IV infusion in combination with BVZ as an IV infusion and FTD-TPI administered orally. Includes a Safety Run-in cohort (non-randomized cohort) prior to randomization.
Standard of care (SOC) alone: BVZ and FTD-TPI (Arm D)ACTIVE_COMPARATORParticipants will receive BVZ as an IV infusion and FTD-TPI administered orally as SOC.

Frequently asked questions about Denikitug

What is Denikitug used for?

Denikitug is being studied in adults with advanced cancers, including microsatellite stable colorectal cancer, HER2-negative gastric, gastroesophageal junction and esophageal adenocarcinomas, and advanced solid tumors. It is an investigational therapy and has not been approved for any indication. Clinical testing is ongoing in Phase 2 and earlier-stage studies.

Who is developing Denikitug?

Denikitug is being developed by Gilead Sciences, Inc., which trades on the Nasdaq under the ticker GILD. The company is running the clinical program, which includes studies of Denikitug given alone or in combination with nivolumab, zimberelimab, or chemotherapy in adults with advanced solid tumors and gastrointestinal cancers.

What phase is Denikitug in?

Denikitug is in Phase 2 clinical development. Two Phase 2 trials are currently recruiting, one in advanced colorectal cancer and one in HER2-negative gastric, gastroesophageal junction and esophageal adenocarcinomas. An earlier Phase 1 study in advanced solid tumors is active but no longer recruiting participants.

What clinical trials is Denikitug in?

Denikitug is being evaluated in three registered studies. NCT07527858 is a recruiting Phase 2 trial in advanced microsatellite stable colorectal cancer with 170 planned participants. NCT07546812 is a recruiting Phase 2 trial in HER2-negative gastric, gastroesophageal junction and esophageal adenocarcinomas with 120 planned participants. NCT05007782 is a Phase 1 advanced solid tumor study with 304 participants.

Is Denikitug the same as GS-1811?

Yes, Denikitug is also known as GS-1811. The two names refer to the same investigational agent, and Gilead Sciences uses GS-1811 in the titles of its registered clinical trials. Searches for either name lead to the same development program in advanced solid tumors and gastrointestinal cancers.

Where are the Denikitug trials being conducted?

The Denikitug trials enroll adults across multiple countries. The Phase 2 colorectal cancer study operates in the United States, Australia, South Korea and Spain, while the Phase 2 gastroesophageal study runs in the United States, Australia, France, South Korea and Spain. The Phase 1 solid tumor study includes sites in the United States, Australia, Canada, Spain and Taiwan.
