What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying the effects of a medication called lumateperone on individuals experiencing Bipolar I Disorder, specifically during manic episodes. Bipolar I Disorder is a mental health condition characterized by extreme mood swings, including emotional highs known as mania. The study aims to evaluate the safety and effectiveness of lumateperone, which is taken in the form of capsules, in treating these manic episodes. Participants in the study will receive either lumateperone or a placebo, which looks like the lumateperone capsule but does not contain the active ingredient.

The purpose of the study is to determine how well lumateperone works in reducing the symptoms of mania over a period of three weeks. During this time, participants will take the medication daily and will be monitored by healthcare professionals. The study will compare the changes in symptoms from the beginning to the end of the three-week period to assess the medication's impact.

The research process

The trial runs in 5 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Joining the study

    Upon joining the study, the patient provides written informed consent.

    The patient is an inpatient, aged between 18 and 75 years, diagnosed with Bipolar I Disorder, specifically experiencing a manic episode or a manic episode with mixed features.

  2. Step 2

    Screening and baseline assessment

    The patient undergoes a screening process to confirm the diagnosis using a structured clinical interview.

    The patient must have a Young Mania Rating Scale (YMRS) total score of 20 or higher and a score of at least 4 on specific items such as irritability and speech.

    The patient is assessed for the severity of illness using the Clinical Global Impressions-Severity (CGI-S) scale, requiring a score of 4 or higher.

  3. Step 3

    Treatment phase

    The patient receives either lumateperone or a placebo, administered orally in capsule form.

    The dosage of lumateperone is 42 mg, taken once daily.

    The treatment lasts for a period of 3 weeks.

  4. Step 4

    Monitoring and evaluation

    Throughout the 3-week treatment period, the patient's symptoms are monitored.

    The primary measure of effectiveness is the change in the YMRS total score from the start to the end of the 3 weeks.

    Secondary evaluation includes changes in the CGI-S score over the same period.

  5. Step 5

    Completion of the study

    At the end of the 3-week treatment period, the patient's participation in the study concludes.

    Final assessments are conducted to evaluate the overall impact of the treatment.

Who can join the trial?

7 criteria

  • The patient must provide written informed consent, which means they agree to participate in the study after understanding what it involves.
  • The patient can be a male or female who is staying in a hospital, and they must be between 18 and 75 years old.
  • The patient must have **Bipolar I Disorder**, specifically experiencing a current episode of **mania** (a period of very high energy and mood) or mania with mixed features (having both manic and depressive symptoms at the same time). This must be confirmed by a trained professional using a special interview process.
  • The current manic episode must have started 4 weeks or less before the first screening visit.
  • The patient must have a **Young Mania Rating Scale (YMRS)** total score of 20 or higher. This scale measures the severity of manic symptoms. They must also score at least 4 on two specific symptoms: irritability, speech, content, and disruptive/aggressive behavior during the screening and baseline visits.
  • The patient must have at least moderate severity of illness, which is determined by a **Clinical Global Impressions-Severity (CGI-S)** total score of 4 or higher during the screening and baseline visits. This score helps assess how severe the disorder is.
  • The patient must have been hospitalized voluntarily before the screening visit or admitted to an inpatient unit at the first visit with a primary diagnosis of mania. This hospital admission must be due to the current manic episode and should not be more than 14 days before the screening visit.

What is already known about the treatment

Lumateperone – Lumateperone is administered orally in the form of a tablet, taken once daily. It is currently being studied in clinical trials for its effectiveness in treating manic episodes associated with Bipolar I Disorder. The medication is primarily indicated for managing symptoms of mania or mixed features in this condition. At the molecular level, lumateperone works by modulating neurotransmitter activity in the brain, particularly affecting serotonin, dopamine, and glutamate pathways. It is classified pharmacologically as an atypical antipsychotic.
