Abstract
Abstract Background: Head and neck (HN) cancer is the 7th most common cancer and 7th leading cause of cancer death worldwide with approximately 930,000 new cases and 470,000 deaths in 2020.1 HN squamous cell carcinoma (HNSCC) accounts for around 90% of HN cancers.2 Options for first-line treatment of patients (pts) with recurrent/metastatic (R/M) HNSCC include cetuximab (anti-epidermal growth factor receptor) in combination with (+) platinum-based chemotherapy (CT) and 5-fluorouracil (5- FU), or immune checkpoint inhibitor (ICI) therapy with single-agent pembrolizumab (anti-programmed cell death-1) or + CT and 5-FU.3-5 Pts who progress on/after CT may receive single-agent cetuximab, ICI pembrolizumab, or ICI nivolumab.3 However, treatment for pts who progress on/after ICI is not clearly defined and rechallenge is not recommended. Thus, there is a need to assess combination immunotherapy approaches. In a Phase 2 study, monalizumab (anti-NKG2A) + cetuximab combination therapy showed encouraging antitumor results in pts with R/M HNSCC who received prior CT and an ICI.6 INTERLINK-1 (NCT04590963) is a Phase 3 global study evaluating the efficacy and safety of monalizumab + cetuximab in pts with R/M HNSCC previously treated with CT and an ICI. Methods: Approximately 624 pts will be randomized 2:1 to monalizumab + cetuximab or placebo + cetuximab until disease progression or another discontinuation criterion is met. All pts will be followed for survival after discontinuation. Eligible pts will have measurable R/M HNSCC (per RECIST v1.1) of the oral cavity, oropharynx, hypopharynx or larynx, which is not amenable to curative therapy and has progressed on/after previous CT. They will have received 1-2 prior systemic regimens for R/M HNSCC, had prior treatment with a PD-(L)1 inhibitor, an ECOG performance status of 0 or 1, and must provide a fresh/recently acquired tumor sample. Key exclusion criteria include prior cetuximab therapy for R/M HNSCC, autoimmune/inflammatory disease or any concurrent anticancer treatment. The primary objective is overall survival (OS) in human papillomavirus-unrelated pts. Key secondary objectives include OS in all randomized pts, progression-free survival, objective response rate, duration of response, disease-related symptoms, functioning and quality of life, pharmacokinetics, safety and tolerability. Study enrollment is ongoing at 210 sites in 25 countries. References: 1. Sung et al. CA Cancer J Clin 2021; 71: 209-49 2. UICC. Head and Neck Cancer. 2014. who.int 3. NCCN®.

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.
