The role of extended-release quetiapine fumarate monotherapy in the treatment of patients with major depressive disorder
Bibliographic record
Abstract
Pharmacotherapy, psychotherapy and other nonpharmacological interventions are used in patients with major depressive disorder (MDD). However, 50% of the patients with MDD fail to achieve a response to first-line antidepressant treatment. In four of five acute monotherapy studies, once-daily extended-release quetiapine fumarate (quetiapine XR) significantly improved depressive symptoms compared with placebo in patients with MDD. One acute monotherapy study demonstrated that neither quetiapine XR nor escitalopram had a statistically significant separation from placebo on the primary endpoint. Quetiapine XR maintenance therapy also significantly reduced the risk of recurrence of a depressive event. No significant improvement in overall quality of life was observed versus placebo except in the acute elderly study. Tolerability findings were consistent with the known pharmacological profile of quetiapine; the most common adverse events were dry mouth, sedation, somnolence and dizziness. Quetiapine XR monotherapy has been approved as a treatment for MDD in a limited number of countries.

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.
