Clobazam is equally safe and efficacious for seizures associated with Lennox–Gastaut syndrome across different age groups: Post hoc analyses of short- and long-term clinical trial results
Bibliographic record
Abstract
The peak age at onset of Lennox-Gastaut syndrome (LGS) is between 3 and 5years. Patients with LGS frequently experience multiple types of treatment-refractory seizures and require lifelong therapy with several antiepileptic drugs. Here, post hoc analyses of clinical trials (phase III trial OV-1012 and open-label extension trial OV-1004) provide short- and long-term efficacy and safety data of adjunctive clobazam in patients with LGS stratified by age at baseline (≥2 to <12years, ≥12 to <17years, and ≥17years). In OV-1012, 301 patients were screened, 238 were randomized, 217 comprised the modified intention-to-treat population, and 177 completed the study. A total of 267/306 patients (61 of 68 from phase II trial OV-1002 and 206 of 238 from phase III trial OV-1012) entered the open-label extension trial. Demographics and clinical characteristics were similar between different age groups in OV-1012 and OV-1004. No differences in efficacy or adverse events were observed across age groups in OV-1012 and OV-1004. The results of these post hoc analyses show that adjunctive clobazam over the short and longterm was similarly effective and well-tolerated in both pediatric and adult patients with LGS.

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.
