Abstract

Objective: Asenapine is approved for bipolar disorder and schizophrenia. This was a 3‐week, randomized, double‐blind, placebo‐controlled trial of asenapine for treating acute bipolar mania. Methods: After a single‐blind placebo run‐in period, adults (n = 488) experiencing manic or mixed episodes were randomized to flexible‐dose sublingual asenapine (10 mg BID on day 1; 5 or 10 mg BID thereafter; n = 194), placebo (n = 104), or oral olanzapine (15 mg BID on day 1; 5–20 mg QD thereafter; n = 191). Primary efficacy, change in Young Mania Rating Scale (YMRS) total score from baseline to day 21, was assessed using analysis of covariance with last observation carried forward [(LOCF); primary analysis]. A mixed model for repeated measures [(MMRM); prespecified secondary analysis] was also used to assess efficacy. Tolerability and safety assessments included adverse events, physical examinations, extrapyramidal symptom ratings, and laboratory values. Results: Mean daily dosages were asenapine 18.2 mg and olanzapine 15.8 mg. Significantly greater least squares (LS) mean ± SE changes in YMRS scores were observed on day 2 with asenapine (−3.0 ± 0.4) and olanzapine (−3.4 ± 0.4) versus placebo (−1.5 ± 0.5, both p < 0.01) and were maintained until day 21 (−10.8 ± 0.8 with asenapine, −12.6 ± 0.8 with olanzapine; both p ≤ 0.0001 versus placebo, −5.5 ± 1.1) with LOCF. The results of MMRM analyses were consistent with those of LOCF. Asenapine had a modest impact on weight and metabolic measures. Conclusions: These results indicate that asenapine is rapidly acting, efficacious, and well tolerated for patients with bipolar I disorder experiencing an acute manic episode.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
