40 Week Extension Study Of Asenapine and Olanzapine For Bipolar Disorder (A7501007)(COMPLETED)(P05857)
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.

|Official Title:||A Double-Blind, 40-Week Continuation Study Evaluating the Safety of Asenapine and Olanzapine in the Treatment of Subjects With Acute Mania Clinical Trial Protocol A7501007 (Secondary Title: ARES)|
- Participants Who Experienced Adverse Event(s) [ Time Frame: Up to 40 weeks ] [ Designated as safety issue: Yes ]
Adverse 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 Findings [ Time Frame: Week 40 or endpoint ] [ Designated as safety issue: Yes ]Physical 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 Electrocardiogram [ Time Frame: Week 40 or endpoint ] [ Designated as safety issue: Yes ]This is the number of participants with electrocardiogram (ECG) adverse events.
- Body Weight [ Time Frame: Baseline to Week 40 or endpoint ] [ Designated as safety issue: Yes ]Weight change from baseline
- Extrapyramidal Symptoms [EPS] [ Time Frame: Week 40 or endpoint ] [ Designated as safety issue: Yes ]
EPS 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 Medications [ Time Frame: Up to 40 weeks ] [ Designated as safety issue: Yes ]Concomitant 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 Girth [ Time Frame: Baseline to Week 40 or endpoint ] [ Designated as safety issue: Yes ]Change in abdominal girth from baseline
- Number of Participants With Markedly Abnormal Vital Sign Changes [ Time Frame: Post-baseline (at Week 4, 12, 20, 28, and 40 or endpoint) ] [ Designated as safety issue: Yes ]
Vital signs measured: sitting blood pressure, heart rate.
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 Range [ Time Frame: Week 40 or endpoint ] [ Designated as safety issue: Yes ]
Normal 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
