E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to assess changes in cognitive function (i.e, concentration, memory) in euthymic (relatively stable mood state) Bipolar patients (type I & II) who are treated with 20 to 80 mg/day of Lurasidone (Latuda) adjunctive therapy over a 6 week period in comparison to those euthymic patients who will be treated with Placebo add-on.
|
|
E.2.2 | Secondary objectives of the trial |
To measure the improvement in patients' mood scores and overall psychiatric status. To look at the number and severity of study drug side effects (safety). To look at the improvement in quality of life of the patients. To look at the improvement in subjective-rated cognitive and daily functioning. To look at the number of patients completing the study (study completion rates) |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients who meet all of the following criteria are eligible to participate in this trial:
1. Males or females aged 19 to 65 years inclusive. 2. DSM.5 diagnosis of Bipolar Type I or Type II Disorder, with or without a history of Psychosis. Bipolar Type II patients must have had 2 definite periods of hypomania in the last 5 years. 3. All patients must be taking either a mood stabilizer (i.e. Lithium or Valproate) (Lamotrigine as a mood stabilizer is acceptable for Bipolar II disorder patients only and not for Bipolar I disorder) or an atypical antipsychotic or a combination of these (two mood stabilizers or a mood stabilizer plus an atypical antipsychotic), at therapeutic doses, for mood stabilization. Those taking two atypical antipsychotics are excluded. Medications and therapeutic doses are: lithium, serum level 0.6-1.2 mEq/L; divalproex/sodium valproate, serum level 350-700 mM/L(45-125 mcg/ml); risperidone 1-6 mg/day; olanzapine 5-30 mg/day; quetiapine IR or XR 300-900 mg/day; aripiprazole 10-30 mg/day; and ziprasidone 80-160 mg/day. Combinations of these medications as outlined above, or the combination of any of them with lamotrigine 100-400 mg daily, or the combination of a mood stabilizer plus asenapine 5-20 mg/day, are also permitted. 4. All concomitant medication must be at a stable dose for two weeks prior to the randomization visit. 5. Clinically stable during the last 4 weeks as assessed by clinical interview. 6. A MADRS and YMRS score less than or equal to 8. 7. Patients who show cognitive impairments, defined as 0.5 standard deviations below the mean or worse (z = -0.5 or lower), on either the WAIS-IV – Coding subtest, or the Rey Auditory Verbal Learning Test (RAVLT) total learning score on trials 1-5 or immediate recall trial, at screening visit. 8. A WAIS-IV vocabulary scaled score >5 (equivalent to estimated IQ 80 or greater). 9. A sufficient level of English or Spanish or Japanese language. 10. Females who are postmenopausal for at least 1 year before the screening visit (confirmed by an FSH test) or are surgically sterile. 11. Females of childbearing potential who are taking contraceptive pills or agree to practice effective double barrier methods of contraception, from the time of signing the informed consent up to the last dose of study drug, and for 7 days after dosing stops, or who agree to completely abstain from heterosexual intercourse. 12. Capability of understanding, consenting to, and complying with study requirements, study visits, and to return to the clinic for follow-up evaluations as specified by the protocol.

E.4 | Principal exclusion criteria |
Patients meeting any of the following criteria are not eligible to participate in the trial:
1. A history of unstable or inadequately treated medical illnesses including moderate to severe brain injury, or neurological illnesses impacting cognitive function. Patients with a personal or family history of cardiac problems will need to undergo EKG at screen visit, and will be excluded if results are abnormal. 2. Patients taking procognitive medications, clozapine, tricyclic antidepressants, first-generation antipsychotics, and cogentin. 3. Those taking two or more antipsychotics. 4. Those taking strong CYP3A4 inhibitors (e.g. clarithromycin, nefazodone, grapefruit juice) or strong CYP3A4 inducers (e.g. carbamazepine, St John's wort (Hypericum perforatum). Please refer to the current Lurasidone SmPC for further listed contraindications.
5. Anticholinergics and stimulants that increase dopamine levels are not permitted 6. Cognitive remediation therapy within 3 months prior to entry or during the double blind phase. 7. Neuromodulation treatment with ECT or rTMS or tDCS or DBS within eight weeks or treatment with an experimental drug within 30 days. 8. History of nonresponse or intolerance to lurasidone. 9. Psychotic disorder other than Bipolar Disorder. 10. Patients who currently meet criteria for anxiety disorder (GAD, OCD, Panic disorder, PTSD). 11. Those with a documented childhood diagnosis of ADHD or other learning disorders. 12. Axis I diagnosis of alcohol/substance abuse or dependence within the past month. 13. Significant risk of harm to self or others. 14. Pregnancy or lactation. 15. Liver function tests (AST and ALT) three times the upper limit of normal.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy measure for the study will be improvement in cognitive performance, as measured by changes in composite cognitive score from baseline to endpoint, extracted from the International Society for Bipolar Disorders–Battery for Assessment of Neurocognition. The co-primary efficacy measure will include changes in functioning from baseline to endpoint measured using UCSD based performance skills assessment-brief version. |

E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Secondary efficacy measures will include: a) improvement in mood scores, based on Montgomery Asberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS) b) improvement in overall psychiatric status, defined as change from baseline to endpoint in score on the Clinical Global Improvement Scale, Bipolar Version, Severity and Change Subscales c) frequency and severity of side effects of lurasidone as reported by patients or determined by investigators d) improvement in quality of life, defined as change from baseline to endpoint in scores on the Quality of Life, Bipolar version, global and subscale ratings e) improvement in subjective-rated cognitive functioning, defined as change from baseline to endpoint in scores on the cognitive complaints in bipolar disorder rating assessment (COBRA) f) improvement in daily functioning, defined as change from baseline to endpoint in scores on the Functioning Assessment Short Test (FAST), Sheehan Disability Scale (SDS) g) study completion rates |
