About this study

Official title: Therapy With Bromocriptine in Patients With Symptomatic Risperidone-Induced Hyperprolactinemia

Antipsychotic drugs can cause a clinically relevant hyperprolactinemia due to blocking the dopamine receptors in the pituitary.Schizophrenic patients suffering from a neuroleptic-induced hyperprolactinemia will be examined endocrinologically. Adverse drug effects and diagnoses will be confirmed by measuring hormones.

Read the detailed description

Antipsychotic drugs can cause a clinically relevant hyperprolactinemia due to blocking the dopamine receptors in the pituitary.Depending on its concentration hyperprolactinemia causes a median hypogonadism with estrogen insufficiency in women and testosterone insufficiency in men by inhibiting the pulsatile GnRH-secretion.The hyperprolactinemia-induced symptoms have been successfully medicated for years with dopamine agonists like bromocriptine.

In patients with psychiatric diseases hyperprolactinemia is usually not treated with dopamine agonist fearing a reexacerbation of the underline psychiatric disease. In a few studies and casuistically the treatment of neuroleptic-induced hyperprolactinemia with bromocriptine has been shown to be effective without causing reexacerbation of psychotic symptoms.

Schizophrenic patients suffering from a neuroleptic-induced hyperprolactinemia (in extremis galactorrhoea and amenorrhoea. in women, loss of libido and erectile dysfunction in men) will be examined endocrinologically. Adverse drug effects and diagnoses will be confirmed by measuring hormones (prolactin, LH, FSH, testosterone, estradiol). In case of a clear symptomatic, neuroleptic-induced hyperprolactinemia patients will be medicated with bromocriptin. Therapeutical success will be determined endocrinologically in week 0, 1, 2, 3, 4, 8, 12, 16, 20 and 24 together with a psychiatric examination (PANSS, HAM-D, Simpson-Angus Scale (SAS)). Safety of therapy will be ensured by the close meshed psychiatric examinations.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Bromocriptin in people with Schizophrenia and Hyperprolactinemia, run by University Hospital, Bonn at 1 site in Germany.

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 4 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: status not confirmed, as of the sponsor's last update on 17 Apr 2006. 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 Germany. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Kai-Uwe Kuehn, MD (0049-(0)228-287-5681, kai-uwe.kuehn@ukb.uni-bonn.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prolactin. The study lists 5 primary outcomes in all. 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 NCT00315081, which also lists 1 linked publication.

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 17 Apr 2006.
