About this trial
This is an interventional treatment trial for Schizophrenia
Eligibility Criteria
Inclusion Criteria:
- Subjects with DSM-IV diagnosis of schizophrenia or schizo-affective disorder for whom antipsychotic monotherapy is indicated.
- Subjects must be free from an acute exacerbation of psychosis for at least 3 months prior to screening.
- Current Clinical Global Impression (CGI) of Severity of Illness score ≤ 3.
Exclusion Criteria:
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
- Evidence or history of a primary DSM-IV axis I diagnosis other than schizophrenia or schizoaffective disorder.
- Any condition possibly affecting drug absorption (e.g., gastrectomy).

Outcomes
Primary Outcome Measures
Safety endpoints: physical and neurological examination, adverse event reports, clinical laboratory tests, vital signs, and 12-lead ECGs throughout the conduct of the study.
Pharmacokinetic endpoints: Primary: AUCtau, Tmax and Cmax of PF-02545920 and PF-01001252 on Days 1 and 13.
Secondary Outcome Measures
Secondary efficacy endpoints include: PANSS, CGI-S, CGI-I, CDSS, CNSVS VS-M cognitive battery, ESRS-A and SSS change from baseline to day 12.
Secondary PK endpoints include AUClast, t1/2, Cavg, Cmax/Cmin ratio on Day 13, and urinary excretion parameters (renal clearance and amount excreted over the dosing interval) of PF-02545920 and PF-01001252 as data permit.
