About this study
Official title: An Open-label Study to Determine the Effect of Switching to Aripiprazole Once Monthly for Subjects With Schizophrenia Experiencing Worsening Sexual Dysfunction With Invega Sustenna or Risperdal Consta
Sexual dysfunction is highly prevalent in schizophrenic patients, affecting up to 80% of men and women. Antipsychotic induced sexual side effects may be a barrier to treatment compliance. Antipsychotics such as Risperdal Consta and Invega Sustenna are known to have higher rates of causing prolactin elevations that may be implicated in sexual dysfunction. The basic premise of this study is to identify patients who believe they have experienced sexual dysfunction on Risperdal Consta or Invega Sustenna and switch to the alternative long acting injectable antipsychotic, Abilify Maintena which tends to lower prolactin levels. Measures of sexual sexual functioning using the self rated 5 item Arizona Sexual Experience Scale (ASEX) as the primary outcome measure will be made over a 3 month period to determine if such a switch is helpful.
Read the detailed description
The study will be performed at several sites and oversight of the study is being monitored by Thomas D Gazda MD PC in accordance with established research principals, the ICH GCP (International Conference on Harmonization Good Clinical Practice) Guideline, FDA regulations and applicable regulatory requirements and local laws.
Source documents will be used to help ensure that patients meet diagnostic criteria for schizophrenia.
All AE (Adverse Event) verbatim descriptions will be performed (investigator terms from the CRF, Clinical Research File) will be classified into standardized medical terminology using the Medical Dictionary for Regulatory Activities (MedDRA).
Treatment emergent AEs (TEAEs) will be summarized. The incidence of TEAEs will be reported as the number (percentage) of subjects with TEAs by SOC (Standard of Care) and PT (Preferred Term). The number(percentage) of subjects with TEAEs will also be summarized by relationship to study drug (possibly related, probably related and not related).
Adverse events will be summarized using the Safety Analysis Sets. The number of AEs and number and incidence (%) of subjects with AEs will be summarized by cohort or dose and overall. For clinically significant events, tome of onset and recovery will be reported.
The number (percentage) of subjects with TEAEs leading to death will be summarized by MedDRA SOC and PT. A subject data listing of all AEs leading to death will be provided.
The number(percentage) of subjects with SAEs will be summarized by MedDRA SOC and PT.
The number (percentage) of subjects with TEAEs leading to discontinuation from study drug will be summarized by MedDRA SOC and PT. A subject data listing of all AEs leading to discontinuation from the study will be provided.
All safety analysis will be performed on the Safety Analysis Sets. Safety data will be summarized on an "as treated" basis using descriptive statistics (e.g. n, mean, standard deviation, median, minimum, maximum, for continuous variables: n(%) for categorical variables). Safety variables include TEAEs, clinical laboratory parameters, vital signs, SST). Study Day 1 for all safety analysis will be defined as the date of the first dose of study drug.
The primary analysis of the primary efficacy endpoint will be based on a one-sample two sided t-test. Missing values will be imputed using the last observation carried forward (LOCF). The ASEX at the end of the 3 months of treatment is considered to be lower than baseline if the 2-sided p-value of the one-sample t-test statistic is less than or equal to 0.05. As additional information, the two-sided 95% confidence interval for the change from baseline in ASEX score will be provided based on t-distribution at the end of the 3 months of aripiprazole once monthly treatment and at each scheduled visit.
As sensitivity analysis, the primary analysis will be repeated based on the observed data; also, a mixed effect analysis of covariance regression will be used to model the change from baseline in ASEX at scheduled visits. Baseline ASEX scores will be the fixed effect, subject will be the random effect, and scheduled visit will be the repeated factor in the model.
The key secondary analysis will be analyzed in the same way as the primary efficacy analysis
The study -conduct duration is approximately 4 months. Screening for subjects will last approximately 8 months for a total study duration of 12 months.
it is projected that a minimum of 22 subjects will be enrolled with an estimate that 19 subjects will complete the study.

|---|---|---|
| Abilify Maintena | Other | Subjects will be switched to Abilify Maintena (Aripiprazole) LAI monthly doses of 400mg, 300mg, 200mg or 160mg and have their sexual functioning reevaluated over a 3 month period to determine if there is any significant sexual functioning improvement. Receives: Drug: Abilify Maintena |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Arizona Sexual Experiences Scale (ASEX) Score
Subjects enrolled in this study will be followed for an average of about 5 months. The ASEX will be done at screening to ensure subjects meet criteria for sexual dysfunction as defined by the scale. In addition subjects must remember at least a 2 point change in the scale since starting Invega Sustenna or Risperdal Consta. Subjects must also score no greater than or equal to 25 on the scale to ensure a baseline of minimal sexual activity. The primary outcome of the study is the change in ASEX score from Baseline to Endpoint. Total scores range from 5 - 30 with the higher scores indicating more sexual dysfunction.
Measured: Baseline and 12 weeks
Secondary outcomes (1)
Prolactin Concentrations ng/ml (Normal Range 4.0 - 15.2ng/ml)
Subjects enrolled in this study will be followed for an average of about 5 months. Serum prolactin concentrations will be measured to assess change from Baseline to Endpoint
Measured: Baseline and Endpoint average of about 5 months

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Abilify Maintena in people with Sexual Dysfunction, run by Gazda, Thomas D., M.D., PC at 1 site in United States.
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 9 inclusion and 6 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: stopped early, as of the sponsor's last update on 11 Apr 2019. 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 United States. 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?
Yes. Results are posted in the registry (first posted 11 Apr 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Arizona Sexual Experiences Scale (ASEX) Score (time frame: Baseline and 12 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02472652, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Apr 2019; AzTrials last refreshed its copy on 27 Oct 2026.
