About this study

Official title: Changes in Hyperprolactinemia Secondary to Antipsychotics After Switching to Quetiapine: a Naturalistic, Prospective, Multicentric Observational Study of 6 Months Follow-up

Hyperprolactinaemia is a common side effect of some antipsychotics (APS), including some atypicals. Clinical consequences of hyperprolactinaemia are broad including amenorrhea, galactorrhea, tender breasts, gynecomastia and sexual dysfunction. Less known but also present is the increased cardiovascular risk, specially in women, disorders of osteoporotic type and a potential increased risk of breast and prostate cancer.

Despite this growing evidence, there are no consistent published data in order to adopt evidence-based decisions that may be beneficial for the patient.

This naturalistic observational 6 months follow-up study on patients with APS-induced hyperprolactinemia aims to obtain more information about the switching approach in cases of hyperprolactinemia secondary to APS and to better establish the role of switching to quetiapine (APS not related with the increase prolactin levels) in this problem.

Read the detailed description

Hyperprolactinaemia is a common side effect of some antipsychotics (APS), including some atypicals. Clinical consequences of hyperprolactinaemia include most remarkably the appearance of amenorrhea, galactorrhea, tender breasts, and gynecomastia - associated with dysmorphophobia and psychological disorders in some cases, particularly in men-. Another common side effect is sexual dysfunction, with decreased libido, anorgasmia, and in men, impotence, reduced volume ejaculated and even backward ejaculation. Less known but also present is the increased cardiovascular risk, specially in women, disorders of osteoporotic type. Furthermore, several authors have related hyperprolactinemic states with the development of breast cancer including a potential worse prognosis of it (Mandala, 1999; Clevenger 2003; Mujagic, 2004), and with the development of metastatic prostate cancer and resistance to hormone therapy in men (Lisonni, 2005)

Despite this growing evidence and the fact that APS with no apparent increase of prolactin levels exist, such as quetiapine or aripiprazole, many clinicians don't even monitor prolactin levels in patients following APS treatment. And when they do, they find there are no consistent published data in order to adopt evidence-based decisions that may be beneficial for the patient.

This naturalistic observational 6 months follow-up study on patients with APS-induced hyperprolactinemia aims to obtain more information about the switching approach in cases of hyperprolactinemia secondary to APS and to better establish the role of switching to quetiapine in this problem.

Questions about this trial

What is this clinical trial studying?

An observational study of APS-related Hyperprolactinaemia and Schizophrenia, run by Investigaciones Médicas Montejo S.L. at 6 sites 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 9 inclusion and 15 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 7 Aug 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites 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.

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?

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?

Variation in prolactin serum levels after switching to quetiapine (time frame: From baseline to endpoint (month 6)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 7 Aug 2009.
