Abstract

fetched live from OpenAlex

Aim This study assessed the efficacy of agomelatine (1,2,3), in the prevention of relapse in non-depressed out-patients with DSM-IV-TR defined Generalized Anxiety Disorder (GAD) and the tolerability. Methods GAD patients received open label agomelatine (25–50 mg/day). At week 4 the dose was increased for patients with insufficient improvement (blinded criteria). At week 16, responders were randomised to maintenance treatment with either agomelatine, or placebo for a 26 week period. Then, agomelatine treated-patients were re-randomised to an agomelatine arm or to a placebo arm, to confirm the lack of discontinuation symptoms (on the DESS check-list). The primary outcome was the time to relapse (days) during the 26 week double-blind treatment period, as estimated using the Kaplan-Meier method. Relapse was defined as HAMA total score > = 15 or withdrawal for lack of efficacy (in the investigator's opinion, based on both HAM-A and CGI scores). Results 477 patients entered the open-label phase and 329 completed this period. 228 patients were randomly assigned to receive agomelatine (114 patients) or placebo (114 patients). The incidence over time of relapse was significantly lower with agomelatine compared to placebo (19.7% versus 31.7% log rank test p = 0.046) during the double-blind treatment period. During the double-blind treatment period 12.4% patients with agomelatine and 9.6% with placebo reported at least one emergent adverse event related to the study treatment. There was no discontinuation syndrome in agomelatine treated patients. Conclusion Agomelatine was efficacious in preventing relapse in GAD, with maintenance of efficacy over 6 months, and good tolerability.

Not 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.
