9 Week Extension Study of Asenapine and Olanzapine in Treatment of Mania (P07007)(COMPLETED)

Bipolar disorder is characterized by mood swings that range 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 the 3 week trial (A7601004 or A7501005) continued on the same treatment that they received in the short term study: asenapine or olanzapine (a medication already approved for the treatment of bipolar mania) for 9 additional weeks. The short term studies (A7501004 and A7501005) were not unblinded until the 9 week extension study was unblinded. Patients treated with placebo in the 3 week short term study were crossed over and treated with Asenapine in the 9 week extension study. Patients who complete the 9 week extension study were eligible to continue in another extension (A7501007) study for an additional 40 weeks.

Treatment and study plan

asenapine

Drug

Asenapine , 9 weeks

Other names: Org 5222

Olanzapine

Drug

Olanzapine, 9 weeks

Primary outcomes

  1. Maintenance of the effect (Asenapine comparable to olanzapine in terms of the reduction of symptoms achieved in the short term (ie. 3 week studies [A7501004 or A7501005]) as measured on the Young Mania Rating Scale

    Time frame: The YMRS is administered at weeks 1, 3, 6 and 9 or endpoint.

Secondary outcomes

  1. Changes on the Clinical Global Impression Scale in which Mania, Depression and Overall Status were assessed.

    Time frame: The Global assessment at Weeks 1,3, 6 and 9 or endpoint

  2. Improvement in symptoms of depression (measured by the Montgomery Asberg Rating Scale of Depression - the MADRS), psychoses (Positive and Negative Symptoms Scale -- the PANSS) and suicidality (ISST-- The InsterSept Suicidality Scale)

    Time frame: PANSS and MADRS administered at weeks 1,3,6 and 9 or endpoint; ISST administered at Weeks 1 and 6.

  3. Changes in the Quality of Life and the TSQM and changes in Readiness to Discharge Questionaire [RDQ]. The investigator's judgment was the basis for a decision to discharge the subject from the hospital.

    Time frame: Quality of Life measures were administered at week 9 or endpoint and the RDQ was administered to inpatients at week 1, 3, 6 and 9.or endpoint.

  4. Physical exams and electrocardiograms findings; changes in vital signs, weight and abdominal girth and hematology and urinalysis.

    Time frame: Physical exams and ECGs at Week 9 or endpoint; Vital signs, weight and abdominal girth at weeks 1, 3, 6 and 9 or endpoint; hematological parameters assessed at weeks 1 and 9 or endpoint; urinalysis was done at Week 9 or endpoint.

  5. Cognition -- the cognitive battery was the same battery that the subject had in the short term study in which they participated -- CNS Vital Signs for A7501005 and Cogstate for A7501004.

    Time frame: The cognitive battery was done at Week 9 or endpoint

  6. Extrapyramidal symptoms were assessed using the AIMS (Involuntary Movement Scale); the BARS (Barnes Akathisia Rating Scale) and the SARS (Simpson Angus Rating Scale).

    Time frame: Extrapyramidal symptoms were assessed at Week 9 or endpoint.

  7. Adverse events and concomitant medications were recorded

    Time frame: Recorded at each visit (Weeks 1, 3, 6, 9 and endpoint)
