Aripiprazole and Prolactin Study (APS)

May 27, 2015 updated by: University of Oxford

Aripiprazole Treatment for Antipsychotic Induced Hyperprolactinaemia in Patients With Severe Mental Illness and Learning Disabilities

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.

  • Willing to allow his or her General Practitioner and consultant to be notified of participation in the study.

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 investigational 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Normalization or reduction in prolactin sufficient to restore gonadal function
Time Frame: Monthly and then 6 monthly intervals over 2 years
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.
Monthly and then 6 monthly intervals over 2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Normalization or improvement in bone mineral density
Time Frame: 2 years
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
2 years
