Abstract

fetched live from OpenAlex

BACKGROUND: Some, but not all, prior investigations suggest armodafinil may have utility as an adjunctive treatment in bipolar I depression. METHODS: Multicenter, randomized, double-blind study in patients aged 18 to 65 years experiencing a depressive episode despite maintenance therapy for bipolar I disorder. Patients were randomized to receive adjunctive armodafinil 150 mg/day or adjunctive placebo for 8 weeks. Primary efficacy outcome was change from baseline in 30-Item Inventory of Depressive Symptomatology-Clinician-Rated (IDS-C30) total score at week 8. Safety and tolerability were monitored. RESULTS: Of 656 patients screened, 399 were randomized, of whom 308 (77 %) were taking a protocol-allowed mood stabilizer as monotherapy. The primary efficacy outcome did not reach statistical significance; however, several secondary efficacy outcomes demonstrated statistically significant advantages for adjunctive armodafinil (n = 197) over adjunctive placebo (n = 196), including Clinical Global Impression of Severity of Illness for depression (weeks 6, 8, and endpoint; all P < 0.05), Global Assessment of Functioning (weeks 4, 8, and endpoint; all P < 0.02), IDS-C30 remitter rates (week 8 and endpoint; both P < 0.02), and mean change from baseline in IDS-C30 total score at week 7 (P < 0.05). Adjunctive armodafinil and adjunctive placebo were generally well tolerated. Although adjunctive armodafinil compared with adjunctive placebo yielded a higher headache rate (15 vs 8 %), it yielded similar (generally favorably low) rates of all-cause discontinuation (16 vs 16 %), adverse event discontinuation (4 vs 5 %), nausea (6 vs 4 %), ≥7 % weight gain (2 vs 5 %), anxiety (4 vs 3 %), insomnia (3 vs 2 %), sedation/somnolence (1 vs 1 %), and hypomania (0 vs <1 %). CONCLUSIONS: In this study, adjunctive armodafinil compared with adjunctive placebo in bipolar I depression did not separate in the primary efficacy outcome but demonstrated advantages for several secondary efficacy outcomes and was generally well tolerated. Additional research is warranted and necessary to better identify clinical predictors (e.g., atypical depressive symptoms, specific anti-manic/mood-stabilizing agents used) that would provide optimized, individualized therapeutics for bipolar depression.

Teacher imitation

Not 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.
