Trial Outcomes & Findings for A Study of the Cataractogenic Potential of Seroquel and Risperdal in the Treatment of Participants With Schizophrenia or Schizoaffective Disorder (NCT NCT00206102)

NCT ID: NCT00206102

Last Updated: 2013-01-14

Results Overview

Presence of C type of cataractogenic potential event in participant was defined if any LOCS II grades of 2, 3, 4, 5 (with any grade of 0, trace,1 at randomization) assessed and agreed by 2 independent, treatment-masked ophthalmologists at any post-randomization assessment in one or both eyes. 0= no cataract; 5 is worst. There are no subscales. 0 is the best, 5 is the worst.

Participant Flow

A 24-month, multi-center, evaluator masked (ophthalmologist), open-label, flexible-dose, parallel-group study, 82 sites recruited Sept 2003 through Oct 2008. In total 1099 participants were randomized by Interactive Voice Response System (IVRS). One excluded participant was randomized before the rand visit, and never returned to any study visits.

Screening for eligibility and must be cross-tapered off of all previous antipsychotic medications

PRIMARY outcome

Timeframe: Randomization to Month 24

Population: The 2-year eye per protocol (E2PP) analysis included all randomized participants who met eye eligibility, had a valid baseline LOCS II evaluation, had reached the study endpoint of either a LOCS II identified cataractogenic potential event or dosed for 21 months without a LOCS II event, and had no major protocol deviations.

Presence of C type of cataractogenic potential event in participant was defined if any LOCS II grades of 2, 3, 4, 5 (with any grade of 0, trace,1 at randomization) assessed and agreed by 2 independent, treatment-masked ophthalmologists at any post-randomization assessment in one or both eyes. 0= no cataract; 5 is worst. There are no subscales. 0 is the best, 5 is the worst.

Population: The intention-to-treat for psychiatric assessments (ITTP) analysis included all randomized participants who had a valid baseline and at least 1 post baseline assessment of PANSS total score, and received at least 1 dose of study medication.

PANSS total score equals sum of the 30-items scores (range: 30-210). Each item has ( 1-7 units), 1 indicates "absent" psychosis symptom, and 7 - "extreme" symptom degree. Change in PANSS total score : total score at month 24 minus total score at randomization.Alleviation of psychotic symptoms are indicated by a negative change in PANSS total score.
