Impact of setanaxib on quality of life outcomes in primary biliary cholangitis in a phase 2 randomized controlled trial
Bibliographic record
Abstract
BACKGROUND: There is a real unmet need for primary biliary cholangitis (PBC) treatments that can improve quality of life impacting symptoms. In this post hoc analysis, we evaluated potential effects of the NADP oxidase 1/4 inhibitor, setanaxib, on patient-reported quality of life from a phase 2 trial in PBC. PATIENTS AND METHODS: The underpinning double-blind, randomized, placebo-controlled trial (NCT03226067) recruited 111 patients with PBC and inadequate response/intolerance to ursodeoxycholic acid. Patients self-administered oral placebo (n=37), setanaxib 400 mg once daily (OD; n=38), or setanaxib 400 mg twice daily (BID; n=36), in addition to ursodeoxycholic acid for 24 weeks. Quality of life outcomes were assessed using the validated PBC-40 questionnaire. Patients were stratified post hoc by baseline fatigue severity. RESULTS: At week 24, patients treated with setanaxib 400 mg BID reported greater mean (SE) absolute reductions from baseline in PBC-40 fatigue domain score [-3.6 (1.3)] versus those receiving setanaxib 400 mg OD [-0.8 (1.0)]) or placebo [0.6 (0.9)]. Similar observations were made across all PBC-40 domains except itch. In the setanaxib 400 mg BID arm, patients with moderate-to-severe fatigue at baseline had a greater reduction in mean fatigue score at week 24 [-5.8 (2.1)] versus those with mild fatigue [-0.6 (0.9)]; results were similar across all domains. Reduced fatigue was correlated with emotional, social, symptom, and cognitive improvements. CONCLUSIONS: These results support further investigation of setanaxib as a treatment for patients with PBC, particularly for those with clinically significant fatigue.

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.
