Safety and clinical activity of durvalumab monotherapy in patients with hepatocellular carcinoma (HCC).
Bibliographic record
Abstract
4071 Background: Durvalumab, an anti-PD-L1 mAb, has shown early and durable clinical activity with manageable safety in an ongoing Phase 1/2, multicenter, open-label study in pts with advanced solid tumors. Interim analyses from the HCC cohort in the dose-expansion part of this study are reported here. Methods: Patients with HCC (Child-Pugh class A) received durvalumab 10 mg/kg i.v. q2w for 12 months or until confirmed progressive disease, whichever occurred first. The primary objective was to evaluate the safety profile; secondary objective was to assess the antitumor activity (investigator-assessed RECIST v1.1). Clinical activity was evaluated for the total HCC population and by viral status. Results: As of Oct 24 2016, 40 HCC pts with median 23.9 (range 2.4–34.7) weeks follow-up received durvalumab. 93% had prior sorafenib. Treatment-related AEs occurred in 80.0% of pts, most commonly fatigue (27.5%), pruritus (25.0%) and elevated aspartate aminotransferase (AST) (22.5%). Grade 3–4 treatment-related AEs were reported in 20.0% of pts, most commonly elevated AST (7.5%) and elevated alanine aminotransferase (5.0%). 7 (17.5%) pts completed the initial 12-month treatment and 7 (17.5%) pts discontinued treatment because of an AE (none related to treatment). There were no deaths due to treatment-related AEs. Clinical activity is presented in the table. 4 pts achieved a PR; 2 were ongoing at data cut-off. Conclusions: Durvalumab had an acceptable safety profile and showed promising antitumor activity and OS in pts with HCC, particularly HCV+ pts. Clinical trial information: NCT01693562.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
