Abstract
Aims: This post hoc analysis evaluated albumin/bilirubin (ALBI) score, an objective measure of liver function, in patients receiving pembrolizumab plus best supportive care (BSC) compared with placebo plus BSC in the KEYNOTE-240 study. Methods: Patients with confirmed hepatocellular carcinoma (HCC) and progression after/intolerance to sorafenib, Child–Pugh class A liver function, and Eastern Cooperative Oncology Group performance status of 0–1 were randomly assigned 2:1 to pembrolizumab 200 mg or placebo intravenously every 3 weeks plus BSC for ⩽35 cycles or until confirmed progression/unacceptable toxicity. Outcomes were assessed by ALBI grade. Results: Of 413 patients, at baseline 116 had an ALBI grade 1 score (pembrolizumab, n = 74; placebo, n = 42) and 279 had an ALBI grade 2 score ( n = 193; n = 86). Change from baseline in ALBI score to the end of treatment was similar in both arms [difference in least squares mean, −0.039; 95% confidence interval (CI): −0.169 to 0.091]. Time to ALBI grade increase was similar in both arms [median for pembrolizumab versus placebo: 7.8 versus 6.9 months; hazard ratio (HR) = 0.863 (95% CI: 0.625–1.192)]. Regardless of baseline ALBI grade, a trend toward improved overall survival was observed with pembrolizumab [grade 1: HR = 0.725 (95% CI: 0.454–1.158); grade 2: HR = 0.827 (95% CI: 0.612–1.119)]. Conclusion: Pembrolizumab did not adversely impact liver function compared with placebo in patients with HCC, as measured by changes in ALBI scores. A trend toward improved overall survival was observed with pembrolizumab in both ALBI grade groups. ClinicalTrials.gov identifier: NCT02702401.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
