Long-Term Antipsychotic Effectiveness in First Episode of Psychosis: A 3-Year Follow-Up Randomized Clinical Trial Comparing Aripiprazole, Quetiapine, and Ziprasidone.

ABSTRACT: Background:Different effectiveness profiles among second-generation antipsychotics may be a key point to optimize treatment in patients suffering a first episode of psychosis to affect long-term outcome. The aim of this study was to compare the clinical effectiveness of aripiprazole, ziprasidone, and quetiapine in the treatment of first episode of psychosis at 3-year follow-up. Method:From October 2005 to January 2011, a prospective, randomized, open-label study was undertaken. Two hundred-two first-episode, drug-naïve patients were randomly assigned to aripiprazole (n=78), ziprasidone (n =62), or quetiapine (n=62) and followed-up for 3 years. The primary effectiveness measure was all cause of treatment discontinuation. In addition, an analysis based on the intention-to-treat principle was conducted in the analysis for clinical efficacy. Results:The overall dropout rate at 3 years reached 19.3%. Treatment discontinuation rates were significantly different among treatment groups (aripiprazole=73.08%, ziprasidone=79.03%, and quetiapine=95.16%) (?2=11.680; P=.001). Statistically significant differences in terms of nonefficacy, nonadherence, and side effects were observed among treatment groups along the 3-year follow-up determining significant differences in time to all-cause discontinuation (log-rank=32.260; P=.001). Significant differences between treatments were found in the categories of sleepiness/sedation (?2=9.617; P=.008) and increased sleep duration (?2=6.192; P=.004). No significant differences were found in the profile of extrapyramidal symptoms. Patients on aripiprazole were more likely to be prescribed benzodiazepines. Conclusions:First-episode psychosis patients on quetiapine were more likely to discontinue treatment due to nonefficacy. Identifying different discontinuation patterns may contribute to optimize treatment selection after first episode of psychosis.

Project description:BACKGROUND:Different effectiveness profiles among antipsychotics may be a key point to optimize treatment in patients suffering a first episode of psychosis to impact on long-term outcome. The aim of this study is to compare the clinical effectiveness of olanzapine, risperidone, haloperidol, aripiprazole, ziprasidone, and quetiapine in the treatment of first episode of psychosis at 3-year follow-up. METHOD:From February 2001 to January 2011, 2 phases of a prospective, randomized, open-label study were undertaken. A total of 376 first-episode drug-naïve patients were randomly assigned to olanzapine (n?=?55), risperidone (n?=?63), haloperidol (n?=?56), aripiprazole (n?=?78), ziprasidone (n?=?62), or quetiapine (n?=?62) and followed up for 3 years. The primary effectiveness measure was all cause of treatment discontinuation. In addition, an analysis based on intention-to-treat principle was conducted in the analysis for clinical efficacy. RESULTS:The overall dropout rate at 3 years reached 20.75%. Treatment discontinuation rates were significantly different among treatment groups (olanzapine?=?69.09, risperidone?=?71.43, aripiprazole?=?73.08%, ziprasidone?=?79.03%, haloperidol?=?89.28%, and quetiapine?=?95.53%) (?2?=?79.86; P?=?.000). Statistically significant differences in terms of lack of efficacy, adherence, and tolerability were observed among treatment groups along the 3-year follow-up, determining significant differences in time to all-cause discontinuation (log-rank?=?92.240; P?=?.000). Significant differences between treatments were found in the categories of sleepiness/sedation, increased sleep duration, akinesia, weight gain, ejaculatory dysfunction, extrapyramidal-symptoms, and amenorrhea. CONCLUSIONS:Olanzapine, risperidone, and aripiprazole presented advantages for the first-line treatment of first episode of psychosis in terms of effectiveness. Identifying different discontinuation patterns may contribute to optimize treatment selection after first episode of psychosis.ClinicalTrials.gov Identifier: NCT02526030 https://clinicaltrials.gov/show/NCT02526030.
