  • Documented MSS or proficient mismatch repair (pMMR) disease by local assessment using a validated polymerase chain reaction (PCR) (microsatellite status) and/or immunohistochemistry (IHC) mismatch repair (MMR) assay is required.
  • Has received up to 2 prior lines of systemic therapy for advanced or metastatic CRC, which must have included at least fluoropyrimidine-, oxaliplatin-, irinotecan-based chemotherapies if indicated; and if applicable: anti-vascular endothelial growth factor (VEGF) therapy, anti epidermal growth factor receptor (EGFR) therapy, encorafenib or adagrasib/sotorasib.
  • Documented progressive disease (PD) by computed tomography (CT) or magnetic resonance imaging (MRI) during or after the most recent therapy per RECIST Version 1.1 criteria by investigator assessment.
  • Eastern Cooperative Oncology Group (ECOG) performance status score of 0-1.
  • Laboratory Assessments
  • Have adequate organ function.
  • Key Exclusion Criteria with:
  • Medical Conditions/History:
  • Significant cardiovascular disease.
  • History of autoimmune disease or active autoimmune disease that has required systemic treatment within 2 years.
  • History of (noninfectious) pneumonitis/interstitial lung disease or current pneumonitis/ interstitial lung disease.
  • History of gastrointestinal (GI) perforation, permanent ileostomy, abdominal abscess or fistula within 6 months, active or uncontrolled GI bleeding within 4 weeks, or any condition associated with significant risk of bleeding or perforation (eg, untreated varices, tumor erosion, recent GI surgery).
  • Prior/Concurrent Therapy or Clinical Study Experience
  • Prior treatment with:
  • Trifluridine-tipiracil, regorafenib, or fruquitinib.
  • Any immuno-oncology therapy.
  • Anticancer biologic agent within 4 weeks prior to randomization or have had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to randomization and have not recovered (ie, Grade 2 or higher is considered not recovered) from AEs from prior anticancer therapy at the time of randomization. Individuals in observational studies are eligible.
  • Allogeneic tissue/solid organ transplantation, including allogeneic stem cell transplantation. Exception: prior corneal transplant without requirement for systemic immunosuppressive agents is allowed.
  • Note: Other protocol defined Inclusion/Exclusion criteria may apply.

The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

anti-CCR8 monoclonal antibody GS-1811. A humanized immunoglobulin G1 (IgG1) afucosylated monoclonal antibody against C-C-chemokine receptor 8 (CCR8), with potential immunomodulating and antineoplastic activities. Upon administration, anti-CCR8 monoclonal antibody GS-1811 targets and binds to CCR8 on CCR8-positive, immunosuppressive tumor-infiltrating T-regulatory (TITR) cells in the tumor microenvironment (TME), and prevents chemokine ligand 1 (CCL1)-CCR8-mediated signaling. GS-1811 depletes CCR8-positive TITR cells via antibody-dependent cell-mediated cytotoxicity (ADCC), which may reactivate antitumor immune responses. CCR8 is specifically expressed by TITR cells in multiple types of cancer and plays a key role in immunosuppression. NCI Drug Dictionary
