What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the safety of ecopipam tablets for treating Tourette Syndrome in children and teenagers. Tourette Syndrome causes involuntary movements and sounds, known as tics. The trial targets those who completed a previous study with ecopipam and might benefit from continued treatment. Individuals with certain mood disorders or unstable medical conditions may not qualify. Participants will continue taking ecopipam to assess its safety for long-term use. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group.

Will I have to stop taking my current medications?

The trial information does not clearly state if you need to stop your current medications, but it mentions that certain medications causing drug interactions are excluded. It's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that ecopipam is likely to be safe for humans?

Research has shown that ecopipam, the treatment under study, is generally well-tolerated. Studies have found that ecopipam works effectively and may be safer than other drugs that block D2 receptors, often used for similar conditions. This suggests it might cause fewer side effects than some other treatments.

In earlier trials, patients taking ecopipam experienced few serious side effects, indicating it is safe for most people. However, individual reactions can vary, so discussing any concerns with a healthcare provider is important. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for Tourette Syndrome?

Ecopipam is unique because it takes a different approach to treating Tourette Syndrome in children and adolescents. Unlike standard treatments like antipsychotics and alpha agonists, which primarily focus on managing symptoms by altering neurotransmitter levels broadly, Ecopipam targets the dopamine D1 receptor specifically. This new mechanism of action could mean fewer side effects and a more targeted therapy, offering hope for better management of Tourette's symptoms. Researchers are excited about Ecopipam because it represents a novel pathway for treatment that could improve quality of life for young patients without the drawbacks associated with current medications.

What evidence suggests that ecopipam might be an effective treatment for Tourette Syndrome?

Research has shown that ecopipam, the treatment under study in this trial, can help reduce tics in people with Tourette Syndrome. Studies have found that ecopipam, which blocks certain chemicals in the brain, is generally safe and well-tolerated. Early results suggest it lessens the severity of tics, which are sudden, repetitive movements or sounds. Overall, ecopipam appears promising for managing symptoms in children and teens with Tourette Syndrome. ^{3 4 6 7 8}

Published Research Related to This Trial

Oxybutynin chloride is effective in managing conditions like neurovesical dysfunction, enuresis, and bladder spasms due to its anticholinergic and muscle relaxant properties, as shown in controlled clinical studies.

The drug's synergistic effects on both the nervous system and muscle relaxation make it a valuable treatment option for patients with uninhibited bladders and primary muscle spasms.

Oxybutynin in bladder spasm, neurogenic bladder, and enuresis. Thompson, IM., Lauvetz, R.[2019]

In a study of 84 children aged 30 months to 15 years taking oxybutynin chloride (Ditropan), 52 experienced atropinic symptoms, indicating a high incidence of side effects, particularly in younger patients.

The frequency of side effects was found to be four times higher in children compared to adults, suggesting that dosage and metabolic differences may contribute to this increased risk, leading to new recommendations for its use.
