Investigation of the effect of food and omeprazole on the relative bioavailability of a single oral dose of 240 mg faldaprevir, a selective inhibitor of HCV NS3/4 protease, in an open-label, randomized, three-way cross-over trial in healthy participants
Bibliographic record
Abstract
OBJECTIVES: This study was conducted to investigate the effect of food and coadministration of omeprazole on the relative bioavailability (BA) of faldaprevir (FDV). METHODS: Fifteen healthy participants participated in this open-label, randomized, three-way cross-over study. Faldaprevir was administered as a 240 mg single dose during fasting state, following intake of a high-fat breakfast, or following omeprazole 40 mg q.d. dosing for 5 days. PK samples were collected on the day of faldaprevir administration. KEY FINDINGS: We found geometric mean (gMean) AUC0-∞ values for faldaprevir of 48 200, 37 900 and 36 000 ng h/ml under the fed, fasted and omeprazole coadministration conditions respectively. Similarly, gMean Cmax values for faldaprevir were 2600, 2030, 1920 ng/ml under the same respective conditions. The adjusted gMean ratio between the fed and fasted condition was approximately 120% for both AUC0-∞ and Cmax , while the ratio of omeprazole coadministration to fasted condition was approximately 94%. Faldaprevir was safe and well tolerated in the study. CONCLUSIONS: Administration of a single dose of 240 mg faldaprevir after high-fat breakfast led to a modest, clinically irrelevant increase in faldaprevir exposure, while coadministration of omeprazole did not influence faldaprevir exposure.

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.
