Study summary

Antipsychotic medicines are used routinely in people with severe mental illness or learning disability. Antipsychotics often induce hyperprolactinemia (high prolactin level) and in almost all women, and some men, this causes hypogonadism (impaired ovarian or testicular function)often with osteoporosis, partly explaining psychiatric patients' high fracture risk. Reducing prolactin by changing antipsychotic or adding a dopamine agonist often worsens psychosis. Adding aripiprazole to current antipsychotic normalizes prolactin in adult schizophrenic patients, without serious side effects. We thus plan a study of add-on aripiprazole in people with antipsychotic induced hyperprolactinemia.

Our main hypothesis is that aripiprazole will normalize or reduce prolactin sufficiently to restore normal ovarian and testicular function. Our secondary hypothesis is that restoration of normal ovarian and testicular function will improve bone mineral density in patients in whom this was reduced at the time of entry into the study.

Inclusion criteria

  • Participants willing and able to give for participation in the study.
  • Males or Females, aged 16-50 years (women), 16-60 (men).
  • Diagnosed with antipsychotic induced hyperprolactinaemia of sufficient severity to induce secondary hypogonadism.
  • Stable dose of current regular antipsychotic medication for at least three months prior to study entry.
  • Female participants of child bearing potential willing to ensure that they or their partner use effective during the study and for 1 month thereafter
  • Able (in the Investigators opinion) and willing to comply with all study requirements.
  • Willing to allow his or her General Practitioner and consultant to be notified of participation in the study.

Exclusion criteria

Exclusion Criteria:

  • Pregnancy or breastfeeding
  • Any significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the study, or may influence the result of the study, or the participant's ability to participate in the study.
  • Plans to donate blood during the study
  • Participants who have participated in another research study involving an product in the past 8 weeks
  • Any significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the study, or may influence the result of the study, or the participant's ability to participate in the study.
  • Plans to donate blood during the study
  • Participants who have participated in another research study involving an investigational product in the past 8 weeks
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Interventions

  • Aripiprazole will be started at 5 mg daily and increased in a treat-to-target fashion by 5 mg steps until the primary outcome or the maximum tolerated or permitted dose of 30 mg is reached

    Also known as: Abilify

What researchers measure

Primary outcomes

  1. Normalization or reduction in prolactin sufficient to restore gonadal function

    Prolactin and sex hormones will be measured on addition of aripiprazole to current antipsychotic treatment. Aripiprazole will be started at 5 mg and uptitrated in a treat-to-target fashion by 5 mg at monthly intervals until prolactin has normalized or decreased sufficiently to restore menses in the women and a normal testosterone in the men. Maximum aripiprazole dose will be 30 mg.

    Time frame: Monthly and then 6 monthly intervals over 2 years

Secondary outcomes

  1. Normalization or improvement in bone mineral density

    Bone mineral density will be measured at baseline in patients aged 20 years or older with a presumed duration of hypogonadism of minimum one year. The measurement will be repeated in those with a low bone mineral density at baseline after two years aripiprazole treatment

    Time frame: 2 years

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 28, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
