About this study
Official title: Phase IV Study of the Effectiveness of Aripiprazole, Quetiapine, and Ziprasidone in the Treatment of First Episode of Non-affective Psychosis Individuals Included in the First Episode Psychosis Clinical Program II (PAFIP II)
The selection of antipsychotic in early stages of the illness is mainly determined by its clinical effectiveness. Second generation antipsychotics (SGAs) are the first line drug treatment for individuals suffering from schizophrenia. It is clear that SGAs are not a homogeneous group and clinical effects and profile of side effects differ between SGAs. Differences among antipsychotics in terms of effectiveness have turned out to be a topic of increasing research interest, although comparisons between the different SGAs are scarce. In first episode of psychosis, SGAs have shown a higher treatment effectiveness compared to first generation antipsychotics (FGAs) (findings primarily driven by Haloperidol). Less evident seems to be the notion that some of the SGAs might be more effective (in terms of treatment discontinuation) than others. Most of the medium-term randomized studies have shown similar rates of all-cause treatment discontinuation in first episode patients treated with different SGAs. It may be concluded that more randomized controlled trails should be accomplished to determine the position of frequently used SGAs in clinical practice. The investigators undertook this study with the major objective of comparing the clinical effectiveness of three widely utilized SGAs (Aripiprazole, Ziprasidone and Quetiapine) in the acute treatment of first-episode non-affective psychosis individuals.
Read the detailed description
Study setting and financial support: data for the present investigation were obtained from an ongoing epidemiological and three-year longitudinal intervention program of first-episode psychosis (PAFIP) conducted at the outpatient clinic and the inpatient unit at the University Hospital Marqués de Valdecilla, Spain. Conforming to international standards for research ethics, this program was approved by the local institutional review board. Patients meeting inclusion criteria and their families provided written informed consent to be included in the PAFIP. The Mental Health Services of Cantabria provided funding for implementing the program. None pharmaceutical company supplied any financial support to it.
Study design: this is a prospective, randomized, flexible-dose, open-label study. At study intake, all patients but eight were antipsychotic naïve. Dose ranges were 5-20 mg /day Aripiprazole, 40-160 mg/day Ziprasidone and 100-600 mg/day Quetiapine. Rapid titration schedule (5-day), until optimal dose was reached, was as a rule used unless severe side effects occur. At the treating physician´s discretion, the dose and type of antipsychotic medication could be changed based on clinical efficacy and the profile of side effects during the follow-up period. Antimuscarinic medication, Lormetazepam and Clonazepam were permitted for clinical reasons. No antimuscarinic agents were administered prophylactically. Antidepressants (Sertraline) and mood stabilizers (lithium) were permitted if clinically needed.
The severity scale of the Clinical Global Impression (CGI) scale, the Brief Psychiatric Rating Scale (BPRS), the Scale for the Assessment of Positive symptoms (SAPS), the Scale for the Assessment of Negative symptoms (SANS), the Calgary Depression Scale for Schizophrenia (CDSS) and the Young Mania Rating Scale (YMRS) were used to evaluate symptomatology. To assess general adverse event experiences the Scale of the Udvalg for Kliniske Undersogelser (UKU), the Simpson-Angus Rating Scale (SARS) and the Barnes Akathisia Scale (BAS) were used. The same trained psychiatrist (BC-F) completed all clinical assessments.
The adverse events were evaluated using the UKU Side effect rating scale. Those treatment-emergent adverse events that occurred at a rate of at least 10% in either treatment group are considered. Treatment-emergent akathisia (BAS) and extrapyramidal symptoms (SARS) were assessed by both baseline-to-end changes and newly emergent categorical changes.

What is being measured
The primary outcome is the main question the study is designed to answer.
Effectiveness of antipsychotics (percentage of discontinuation of the initially assigned treatment)
The main outcomes of effectiveness were the percentage of discontinuation of the initially assigned treatment (patients who completed the 6 weeks follow-up assessment and changed initial antipsychotic) and the mean time to all-cause medication discontinuation. Four reasons for the discontinuation were recorded: 1.- insufficient efficacy; 2.- marked side-effects; 3.- patient reported non-adherence and 4.- other causes. If more than one reason for discontinuation was present, the most important reason according to the above ranking was selected. Data on antipsychotic treatment (doses, discontinuation and concomitant medications) were registered weekly during the first 4 weeks and at 6 week. Insufficient efficacy was established at the treating physician´s judgment only after at least three weeks of treatment.
Measured: 6 weeks
Secondary outcomes (5)
Change in general psychopathology measured by the Brief Psychiatric Rating Scale (BPRS)
Measured by BPRS. The patients were defined as responders to the optimum dose of antipsychotic at 6 weeks if a >40% reduction of the BPRS scores at intake and had a CGI severity score of ≤ 4. In addition, we also explored to rate of responders if a cutoff of ≥ 50% reduction of the BPRS total scores at intake was used.
Measured: 6 weeks, 3 months and 1 year
Change in positive and negative symptoms measured by the Scale for the Assessment of Negative and Positive Symptoms (SANS and SAPS)
Measured by SANS and SAPS.
Measured: 6 weeks, 3 months and 1 year
Change in the severity of depressive symptoms measured by the Calgary Depression Scale (CDS)
Measured by CDS.
Measured: 6 weeks, 3 months and 1 year
Change in maniac symptoms measured by the Young Mania Rating Scale (YMRS)
Measured by YMRS.
Measured: 6 weeks, 3 months and 1 year
Adherence to treatment
Measured: 1 year

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Second generation antipsychotics (SGAs) are the first line drug treatment for individuals suffering from schizophrenia. It is clear that SGAs are not a homogeneous group and clinical effects and profile of side effects differ between SGAs.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Aripiprazole, Quetiapine and Ziprasidone in people with Schizophrenia and Psychotic Disorders, run by Fundación Marques de Valdecilla at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
