A phase 3, randomized study of adjuvant rilvegostomig plus chemotherapy in resected biliary tract cancer: ARTEMIDE-Biliary01.
Bibliographic record
Abstract
TPS4199 Background: Biliary tract cancer (BTC) is a rare but aggressive heterogenous group of gastrointestinal cancers that arise from the intra- or extrahepatic bile ducts (cholangiocarcinoma [CCA]) or the gallbladder (GBC). In early-stage disease following curative resection, adjuvant chemotherapy with a fluoropyrimidine- or gemcitabine-based regimen is usually recommended, however, recurrence rates remain high (e.g. in the BILCAP study, 5-year recurrence-free survival with adjuvant capecitabine was 34%). Immunotherapy is efficacious as adjuvant therapy in other cancer types. Results from the TOPAZ-1 and KEYNOTE-966 studies support combining immunotherapy and chemotherapy in advanced BTC, including in locally advanced non-metastatic disease. Furthermore, dual inhibition of programmed cell death-1 (PD-1) or programmed cell death ligand-1 (PD-L1) and the novel immune checkpoint, T cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain (TIGIT), has shown promising results across multiple tumor types without major increases in high-grade toxicity compared with PD-1 or PD-L1 inhibition alone. Rilvegostomig is an anti-PD-1/-TIGIT bi-specific monoclonal antibody that appears active and well tolerated in non-small-cell lung cancer. ARTEMIDE-Biliary01 will investigate the efficacy of rilvegostomig plus standard of care adjuvant chemotherapy in patients with BTC after curative intent resection. Methods: ARTEMIDE-Biliary01 (NCT06109779) is a Phase 3, randomized, double-blind, placebo-controlled, multicenter, global study to assess the efficacy and tolerability of rilvegostomig IV every three weeks versus placebo in combination with investigator's choice of chemotherapy (capecitabine, S-1 [tegafur/gimeracil/oteracil] or gemcitabine/cisplatin) as adjuvant treatment in patients with BTC after curative intent resection. This study will enroll approximately 750 adults with histologically confirmed adenocarcinoma of the biliary tract (intrahepatic or extrahepatic CCA or muscle-invasive GBC) after macroscopically complete resection (R0 or R1) and an ECOG PS of 0–1. Key exclusion criteria include locally advanced, unresectable, or metastatic disease at initial diagnosis and any anti-cancer therapy for BTC prior to surgery. The primary endpoint is recurrence-free survival, and the key secondary endpoint is overall survival. Additional endpoints include progression-free survival following recurrence, patient-reported tolerability, and safety. Enrollment has begun, and approximately 200 sites will be recruiting globally across Asia, Australia, Europe, North America, and South America. Clinical trial information: NCT06109779 .

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
