Conditions

Bipolar Disorder

Brief summary

Bipolar disorder is characterized by mood swings that range from from high (manic) to low (depressed) states. Sometimes, symptoms of both depression and mania are present (mixed episodes). Asenapine is an investigational medication for the treatment of manic or mixed episodes of bipolar disorder. Patients who completed study A7501006 (a 9 week extension study) could continue with the same treatment that they had been receiving: asenapine or olanzapine (a medication that is already approved for the treatment of bipolar mania) in a 40 -week continuation study.

MeasureTime frameDescription
Participants Who Experienced Adverse Event(s)Up to 40 weeksAdverse event (AE) data, both serious and non-serious, were collected. Serious AEs were also collected up to 30 days post last dose of study drug. An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product. It does not necessarily have to have a causal relationship with this treatment. An AE is defined as serious if it results in death, is life-threatening, requires in-patient hospitalization or prolongs existing hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect.
Number of Participants With Abnormal Physical Examination FindingsWeek 40 or endpointPhysical exam (PE) included assessment of general appearance, skin, head, eyes, ears, nose, throat, lungs, blood pressure, cardiac rhythm & rate, neurologic status, and abdomen. The findings were deemed to be normal/abnormal based on the clinical judgment of the investigator.
Number of Participants With Abnormal ElectrocardiogramWeek 40 or endpointThis is the number of participants with electrocardiogram (ECG) adverse events.
Body WeightBaseline to Week 40 or endpointWeight change from baseline
Extrapyramidal Symptoms [EPS]Week 40 or endpointEPS was assessed using the (1) involuntary movement scale \[AIMS\], (2) Barnes Akathisia Rating Scale \[BARS\], and (3) Simpson Angus Rating Scale SARS. AIMS score range 0-4; higher scores indicate greater symptom severity. BARS score rang 0-9; higher scores indicate greater severity of akathisia. SARS score range 0-40; higher scores indicate greater degree of Parkinsonism.
Concomitant MedicationsUp to 40 weeksConcomitant medications are any medications taken on or after the date of first dose of double-blind study drug through the date of last dose of double-blind study drug.
Abdominal GirthBaseline to Week 40 or endpointChange in abdominal girth from baseline
Number of Participants With Markedly Abnormal Vital Sign ChangesPost-baseline (at Week 4, 12, 20, 28, and 40 or endpoint)Vital signs measured: sitting blood pressure, heart rate. Definitions: Markedly abnormal decreases: heart rate (HR) - if ≤50 bpm and decrease from baseline of ≥15 beats per minute (bpm); systolic blood pressure (SBP) - if ≤90 mm Hg and decrease from baseline of ≥20 mm Hg; diastolic blood pressure (DBP) - if ≤50 mm Hg and decrease from baseline of ≥15 mm Hg. Markedly abnormal increases: HR - if ≥110 bpm and increase from baseline of ≥15 bpm; SBP - if ≥180 mm Hg and increase from baseline of ≥20 mm Hg; DBP - if ≥105 mm Hg and increase from baseline of ≥15 mm Hg.
Number of Participants With Laboratory Values Outside Normal RangeWeek 40 or endpointNormal ranges were provided by the central laboratory. Biochemistry = electrolytes, creatine kinase, liver enzymes, blood urea nitrogen, creatinine, alkaline phosphatase, protein, albumin Metabolic chemistry = cholesterol, glucose, triglycerides, glycosylated hemoglobin Endocrinology/miscellaneous = insulin, prolactin Hematology = hemoglobin, red blood cell count, white blood cell count, platelets, hematocrit, neutrophils, lymphocytes, monocytes, eosinophils, basophils
