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 long-term safety of a medication called ecopipam in individuals with Tourette's Disorder. Tourette's Disorder is a condition characterized by repetitive movements or unwanted sounds, known as tics, that are difficult to control. The study involves children, adolescents, and adults who have previously participated in related studies and are eligible to continue. The medication being tested, ecopipam, is taken in the form of tablets and is designed to help manage the symptoms of Tourette's Disorder.

The purpose of this study is to evaluate how safe and tolerable ecopipam is when used over a long period. Participants will take ecopipam tablets orally, which means they will swallow the tablets. The study will monitor participants for any side effects or issues that may arise from taking the medication over time. The study does not involve any comparison with a placebo, and all participants will receive the actual medication.

Participants in this study will be observed for a period of up to 105 days. During this time, they will take ecopipam tablets at varying doses, depending on their specific needs and previous study participation. The study aims to ensure that ecopipam is safe for long-term use in managing the symptoms of Tourette's Disorder, providing valuable information for future treatment options.

The research process

The trial runs in 4 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial visit

    Upon joining the study, you will attend an initial visit. During this visit, the study team will review your medical history and confirm your eligibility to participate in the trial. This includes ensuring you have completed previous related studies if applicable.

    You will be informed about the study procedures, and any questions you have will be addressed. You will also be asked to sign a consent form to confirm your willingness to participate.

  2. Step 2

    Medication administration

    You will be given **Ecopipam** tablets to take orally. The dosage may vary, including options such as 11.2 mg, 22.4 mg, 33.6 mg, 44.8 mg, 67.2 mg, or 89.6 mg. The specific dosage and frequency will be determined by the study team based on your individual needs.

    The medication is intended to be taken regularly as instructed by the study team. It is important to follow the dosage schedule provided to you.

  3. Step 3

    Regular follow-up visits

    Throughout the study, you will have regular follow-up visits with the study team. These visits are designed to monitor your health and the effects of the medication.

    During these visits, you may undergo various assessments and provide feedback on your experience with the medication. The study team will also check for any side effects or changes in your condition.

  4. Step 4

    End of study procedures

    At the end of the study, you will have a final visit with the study team. This visit will include a comprehensive evaluation of your health and a discussion about your experience during the trial.

    You will be provided with information on any necessary follow-up care or additional steps to take after the study concludes.

Investigated drugs

Ecopipam is a medication being studied for its long-term safety in people with Tourette's Disorder. Tourette's Disorder is a condition that causes people to have involuntary movements and sounds, known as tics. Ecopipam works by affecting certain chemicals in the brain that are thought to be involved in causing these tics. The goal of this study is to see if Ecopipam can be used safely over a long period of time in children, teenagers, and adults who have Tourette's Disorder. Participants in this study have previously taken part in other related studies, and this trial aims to ensure that Ecopipam is safe and well-tolerated when used for an extended period.

What is already known about the treatment

Ecopipam – Ecopipam is administered in tablet form and is taken orally. It is currently being studied in clinical trials to assess its long-term safety for treating Tourette's Disorder in children, adolescents, and adults. The main therapeutic use of Ecopipam is to help manage the symptoms of Tourette's Disorder, which often include involuntary movements and vocalizations. At the molecular level, Ecopipam works by blocking certain receptors in the brain that are involved in dopamine signaling, which is thought to help reduce the symptoms of Tourette's. It is classified pharmacologically as a dopamine receptor antagonist.

Investigated diseases

Tourette's Disorder – Tourette's Disorder is a neurological condition characterized by repetitive, involuntary movements and vocalizations called tics. These tics can be motor, such as blinking or shrugging, or vocal, such as grunting or repeating words. The disorder typically begins in childhood, with symptoms often appearing between the ages of 5 and 10. Tics can vary in frequency and intensity, sometimes becoming more noticeable during periods of stress or excitement. Over time, the type and severity of tics may change, with some individuals experiencing a reduction in symptoms as they age. The exact cause of Tourette's Disorder is not fully understood, but it is believed to involve a combination of genetic and environmental factors.
