Study summary

The goal of this observational study is to learn about how long-acting injectable antipsychotic (LAIA) medications are affected by the changes that take place in the body during pregnancy, and how much an unborn baby is exposed to. The investigators are also interested in the amount of these drugs that enters into breastmilk and taken by babies during breastfeeding.

In addition to their regular clinic visits to receive long-acting mental health medicine injection, participants will be invited for up to four study visits between day 2 and 14 after the injection. This will happen only once during pregnancy, and once during the breastfeeding period to collect a few drops of blood on special filter paper card from the finger using safety lancet. A few drops of breastmilk will also be collected. Immediately after delivery, a few drops of blood will be collected from the mother, umbilical cord and the baby heel.

The investigators will use these samples to determine the amount of the drug in the body during pregnancy and compare this to the amount during the breastfeeding period. Additionally, every month during the third trimester, and during the first 3 months postpartum, participants will complete a questionnaire (using the Liverpool University Neuroleptic Side Effect Scale) to document how they are feeling. Clinical improvement will be documented by the primary care provider using the Clinical Global Impressions Scale.

Findings from this study are expected to help healthcare providers to understand these drugs better so that they can make informed decisions about if and how to use these drugs in women who become pregnant or are breastfeeding.

Primary Objectives

  1. To determine the magnitude of changes (if any) in the pharmacokinetics of selected LAIAs during pregnancy and assess the extent of fetal exposure at delivery.
  2. To describe breastmilk pharmacokinetics of selected LAIAs and the extent of breastfed infant exposure.

Secondary Objectives

  1. To assess safety and clinical outcomes following LAIA use during pregnancy and postpartum.
  2. To explore sources of variability in maternal and fetal/breastfed infant LAIA exposure.

Study population

Pregnant and postpartum women, at least 18 years old receiving maintenance dose of long-acting injectable antipsychotics (LAIA).

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

  • Scheduled to receive at least one injection before delivery (if pregnant) or before week 12 postpartum (if breastfeeding).
  • At least 18 of age at study entry.

Exclusion criteria

Exclusion Criteria:

  • Unable to understand study information.
  • Unable to provide written .
  • Known to study medication.
  • Record of poor medication adherence.
  • Personal circumstances will not allow completion of the schedule of study activities.
  • Concurrent use of agents with known or uncertain interaction with study drug.
  • Currently experiencing severe pregnancy related complications
Terms in these criteria, in plain language(2)

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
