Key inclusion & exclusion criteria

Inclusion criteria:
1. Subjects must meet DSM-IV criteria for Bipolar I Disorder, Most Recent Episode Manic or Mixed at the time of screening. Other Axis I and II disorders except those listed in the exclusion criteria are acceptable. All diagnoses will be confirmed by the Mini International Neuropsychiatric Interview (MINI);
2. Subjects must have been taking the mood stabilizers, lithium or valproate, as part of treatment for Bipolar I Disorder for a minimum of 2 weeks prior to screening. At screening, the therapeutic drug levels of subjects on lithium and valproate should be within 0.6-1.2 mEq/L and 50-125 mcg/ml, respectively. All oral dosage forms of lithium and valproate (i.e. immediate and modified release tablets, or oral solutions) are allowed. The valproate preparations may contain valproate, valproic acid, or divalproex sodium;
3. Subjects must receive a total score of at least 20 on the Young Mania Rating Scale (YMRS) at screening and at baseline;
4. Subjects must have a history of experiencing at least one prior documented manic or mixed episode that required medical treatment within 3 years prior to screening;
5. Subjects must be between 18 (or the minimum age to provide informed consent in the jurisdiction in which the study is taking place, whichever is older) and 65 years of age inclusive;
6. Female subjects must be either postmenopausal for at least 1 year, surgically sterile, abstinent, or practicing an effective method of birth control if sexually active (e.g., prescription oral contraceptives, contraceptive injections, intrauterine device, double-barrier method, contraceptive patch, male partner sterilization). Female subjects must also have a negative urine pregnancy test at screening, baseline, and other time points throughout study;
7. Subjects must have signed an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study. It is acceptable to have additional signatures if required by local regulations;
8. Subjects must have signed the informed consent for genetic testing indicating whether they do or do not wish to participate in the genetic component of the study (where local regulations permit). Participation in the genetic component is not required for participation in the study;
9. Subjects must be able and willing to comply with self-administration of medication, or have consistent help/support available;
10. Subjects must be able and willing to meet or perform study requirements. Note: If a subject is unable to read the question, study personnel may read documents and the subject may then mark his/her choice. Inability to complete a self-administered questionnaire due to the acute manic state at entry should not preclude a subject from participating.

Primary Outcome(s)

Primary end point(s): primary efficacy end point is the change in the total YMRS score from baseline to the last post-baseline assessment during 6 weeks of treatment.

Main Objective: The primary objective of this trial is to assess the adjunctive anti-manic efficacy of paliperidone ER relative to placebo during 6 weeks of treatment in subjects with Bipolar I Disorder who are suffering from a manic episode and who already have been taking lithium or valproate for treatment of Bipolar I Disorder. The primary efficacy measure is the change from baseline to endpoint in the Young Mania Rating Scale (YMRS) total score at study end.

Secondary Objective: 1. To assess the safety and tolerability of paliperidone ER.
2. To assess the impact on depressive symptoms during 6 weeks of treatment based on the total MADRS score.
3. To explore the pharmacokinetics of paliperidone in subjects with Bipolar I Disorder, and to assess possible pharmacokinetic relationships to efficacy and safety of paliperidone ER.
4. To evaluate the impact of paliperidone ER therapy on global functioning.
5. To evaluate the impact of paliperidone ER therapy on overall subject reported quality of life.
6. To allow for determination of the genes/genotypes that may be related to the response or metabolism of paliperidone ER or to Bipolar I Disorder (as necessary).
