This trial is in two stages: 12-month double-blind treatment of lurasidone HCl 40 mg oral tablets with matching placebo, and risperidone over-encapsulated oral capsules (2, 4 or 6 mg) with matching placebo in double-dummy design. Once-daily dosing for all medications (Stage 1). Followed by 6-month open-label extension phase (Stage 2). During the open-label period all participants will (after a single-blind, 3 day placebo washout) initially receive lurasidone HCl 80 mg/day, after 7 days of study medication the dose may be adjusted between 40-120 mg/day.

Intervention type



Phase III

Drug names

Lurasidone, risperidone

Primary outcome measure

Assess long-term safety and tolerability of lurasidone by measuring proportion of subjects with adverse events and serious adverse events. These will be assessed at 12 months. Safety will also be assessed at 18 months.

1. To measure changes in the following:
1.1. Weight at Screening, baseline, Week 12, Month 6, 9 and 12 and then monthly until 18 months
1.2. BMI at Screening, baseline, Week 12, Month 6, 9 and 12 and then monthly until 18 months
1.3. Waist circumference at baseline, 6, 12 and 18 months
1.4. Serum prolactin at Screening, baseline, 6 and 12 weeks, 6, 12, 13, 15 and 18 months
1.5. Testosterone at baseline, 6 and 12 weeks, 6, 12, 15 and 18
1.6. N-telopeptide (NTx) at Screening, baseline, 6, 9, 12, 15 and 18 months
1.7. Osteocalcin at Screening, baseline, 6, 9, 12, 15 and 18 months
1.8. Bone alkaline phosphatise at Screening, baseline, 6, 9, 12, 15 and 18 months
1.9. Parathyroid hormone (PTH) at Screening, baseline, 6, 9, 12, 15 and 18 months
1.10. ECG parameters at Screening, baseline, 7 days, 6 weeks, 6, 12 and 18 months
2. To evaluate long-term efficacy of lurasidone and risperidone by changes in the following at 12 months:
2.1. Positive and Negative Symptom Scale (PANSS) score
2.2. Clinical global impression of severity (CGI-S) score
2.3. Montgomery and Asberg Depression Rating Scale (MADRS) score
3. Demonstrate lurasidone is as effective as risperidone in maintaining clinical stability and preventing relapse, assessed at 12 months
