Alirocumab dosing patterns during 40 months of open-label treatment in patients with heterozygous familial hypercholesterolemia
Bibliographic record
Abstract
BACKGROUND: ODYSSEY OLE (NCT01954394) was an open-label extension (OLE) study for patients with heterozygous familial hypercholesterolemia (HeFH) who had completed previous phase 3 clinical trials with alirocumab. Alirocumab dose could be increased or decreased as per physician judgment. OBJECTIVE: To assess how the alirocumab dosing strategy was used by physicians during OLE. METHODS: Patients who entered OLE on a starting dose of alirocumab 75 mg every 2 weeks (Q2W) were included in the analysis (those from FH I, FH II, and LONG TERM trials). Those who completed LONG TERM entered an 8-week washout period before receiving alirocumab 75 mg Q2W at the start of OLE. From week 12, dose adjustment from 75 to 150 mg Q2W, or vice versa, was possible, based on the physician's clinical judgment. RESULTS: In total, 909 patients with HeFH completed the 3 parent studies and were treated during OLE for a duration of up to 40 months. Most patients (56.7%) were maintained on 75 mg Q2W throughout OLE, whereas 43.3% of patients had their dose increased to 150 mg Q2W. The dose was subsequently decreased in 7.4% of the patients in whom alirocumab was initially uptitrated. Overall, treatment-emergent adverse events were similar between those who had received placebo or alirocumab in the parent studies. CONCLUSIONS: In the opinion of physicians, alirocumab 75 mg Q2W enabled over half of patients with HeFH to achieve sufficient low-density lipoprotein cholesterol lowering.

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.
