The purpose of this study is to assess the safety, pharmacokinetics and efficacy of 3 fixed doses of MP-214 orally administered once daily to patients with schizophrenia. MP-214 tablets will be administered to patients starting at an initial dose, followed by up-titration to a fixed dose (low, medium or high) for 14 days.

Change From Baseline in the Clinical Global Impression-Severity (CGI-S) Score at Day 14 (Last Observation Carried Forward; LOCF)

CGI-S is a 7-point scale to assess the global severity of the participant's illness. CGI-S scores range from 1 (normal, not ill at all) to 7 (extremely ill).

Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Day 14 (Last Observation Carried Forward; LOCF)

PANSS score is a 30-item rating scale to assess both the positive and negative symptom syndromes of patients with schizophrenia. Each item is scored on a 7-point scale, from 1 (absent) to 7 (extreme). The PANSS total score of the 30 PANSS items ranges from 30 to 210. High scores indicate greater severity of symptoms.

The Clinical Global Impression-Improvement (CGI-I) Score at Day 14 (Last Observation Carried Forward; LOCF)

CGI-I is a 7-point scale to assess the global improvement of the participant's illness relative to baseline. CGI-I scores range from 1 (very much improved) to 7 (very much worse).
