Brief Summary:

Arm Intervention/treatment
Experimental: Cognitive Remediation
Cognitive remediation intervention will be administered in small group settings twice weekly for 30 sessions and will utilize computerized and verbal group training exercises to address basic skills such as auditory processing, attention, processing speed, and verbal working memory and learning, as well as intermediate and complex skills such as deductive reasoning, planning and sequencing, set shifting, and complex problem solving.
Drug: Cognitive Remediation
Cognitive remediation intervention will be administered in small group settings twice weekly for 30 sessions and will utilize computerized and verbal group training exercises to address basic skills such as auditory processing, attention, processing speed, and verbal working memory and learning, as well as intermediate and complex skills such as deductive reasoning, planning and sequencing, set shifting, and complex problem solving.

No Intervention: Cognitive activity control group
This is a non-specific mental activity control condition, conducted two times per week for a total of 30 sessions.

Primary Outcome Measures :
  1. Cognitive Function Measured by MCCB Composite Score [ Time Frame: 4-6 month period ]

    The MATRICS Consensus Cognitive Battery (MCCB) will be used to assess cognitive function. The MCCB composite score is comprised of sub-scale measures of: a) working memory; b) attention and vigilance; c) verbal learning; d) visual learning; e) speed of processing; f) reason and problem solving; and g) social cognition. The MCCB takes 90 minutes or less to complete.

    MCCB assessed 4 times: prestabilization (screening), randomization (after 6-8 weeks of lurasidone stabilization, prior to initial cognitive remediation), midpoint (after 20 cognitive remediation session), and study completion (final visit after 30 cognitive remediation sessions).

    MCCB composite scores are reported as t-scores where a t-score = 50 is the population average. Every 10 points is one standard deviation. There is no range as scores are as far from population average.

  2. Cognitive Function as Measured by the University of California, San Diego, Performance-Based Skills Assessment-Brief (UPSA-B) Scale [ Time Frame: 4-6 month period ]
    The UPSA-B assesses functional capacity to perform tasks similar to those in daily life. Raw scores are converted into scaled scores ranging from 0-100, with higher scores indicating better functional capacity.

Secondary Outcome Measures :
  1. Cognition as Measured by Cognitive Assessment Interview (CAI) [ Time Frame: 4-6 month period ]

    Cognitive Assessment Interview was used to obtain information about cognitive functioning from both subject and an informant. Composite CAI scores were reported. Scale ranges from 1-7 with the following anchors:

    1. Normal, no cognitive impairment
    2. Borderline impairment
    3. Mildly impaired
    4. Moderately impaired
    5. Markedly impaired
    6. Severely impaired
    7. Among the most extremely impaired

  2. Efficacy as Measured by Positive and Negative Syndrome Scale (PANSS) [ Time Frame: 4-6 month period ]

    Total PANSS score with 30 items. Each item is rated 1-7 so the minimum Total PANSS score =30 and the maximum is 210. Anchors for each item are as follows, the higher values represent an increase in severity of symptoms:

    1. Absent
    2. Minimal
    3. Mild
    4. Moderate
    5. Moderately severe
    6. Severe
    7. Extremely severe

Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female between 18-55 years of age who meet DSM-IV-TR criteria for schizophrenia or schizoaffective disorder confirmed by the Structured Clinical Interview for DSM-IV Clinical trial version (SCID-CT version). Duration of illness > 1 year. Outpatient status.
  • Change in antipsychotic medication is clinically warranted as evidenced by

    • persistent psychosis despite adequate dose and duration of antipsychotic, or * inability to achieve therapeutic dose because of dose-limiting side effects,
    • persistent side effects that either cause significant subjective distress or significantly increase medical risks, such as substantial weight gain or metabolic disturbances, or
    • patient preference to switch and treating psychiatrist is in agreement.
  • No behaviors suggesting potential danger to self or others over the 6 months prior to participation.
  • For the last 2 weeks of lurasidone stabilization phase, a score of 4 or less on PANSS items of conceptual disorganization, hallucinations, suspiciousness and unusual thought content items.
  • At end of lurasidone stabilization phase, Simpson-Angus Scale total score <
  • At end of lurasidone stabilization phase, Calgary Depression Scale total score <10.
  • No acute medical problems; any chronic medical condition (e.g. hypertension) consistently treated and stable during the 1 month prior to participation.
  • Able to provide signed informed consent and to cooperate with all study procedures.
  • Able to attend twice weekly sessions (each lasting approximately 75 minutes) for cognitive remediation or active control sessions for the ~6 month duration of the cognitive remediation phase of the study.
  • Must meet the following cognitive performance criteria:

    • Able to complete the baseline MATRICS validly at baseline as assessed by NP tester.
    • Raw score of 12 or greater on the WTAR (Wechsler Test of Adult Reading) at screening.
  • Women who can become pregnant must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 4 weeks after the study in such a manner that the risk of pregnancy is minimized. Acceptable methods include oral, injectable or implanted contraceptives, intrauterine devices or barrier methods such as condoms, diaphragm and spermicides. Women who can become pregnant must have a negative urine pregnancy test at the Screening Visit. Women who can become pregnant include anyone who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation or bilateral oophorectomy), or is not postmenopausal (defined as amenorrhea 12 consecutive months).

Exclusion Criteria:

  • Documented history of learning disability.

Active medical conditions that are minor or well controlled are not exclusionary if they do not affect risk to the patient of the study results. For example, the following are not exclusionary: a) stable and well-controlled hypertension; b) asthma (no serious attacks in the past year); c) hypothyroidism (TSH within normal limits).

  • History of alcohol or substance abuse or dependence during the 6 months prior to participation.
  • Participation in a clinical trial involving an investigational medication within 3 months prior to participation or 2 or more investigational drug trials in the preceding 12 months.
