A study to evaluate the safety and efficacy of new drug in male patients aged 18 to 50 with Tourette Syndrome (TS).

About this study

Tourette Syndrome (TS) is a neurological (brain) disorder characterised by rapid, repetitive and involuntary muscle movements and vocalisations (tics) often involving behavioural difficulties, including:

  • Attention-deficit hyperactivity disorder (ADHD)
  • Obsessive-compulsive disorder (OCD).

Although TS is rare, it is two to four times more common in males and is most prominent during childhood and adolescence.

Current treatments for TS are antipsychotic drugs, which are often only moderately effective and result in a high incidence of side effects.

The investigational product, NOE-105 inhibits a specific enzyme in the body (PDE10A). The inhibition of PDE10A in the brain may lead to a reduction in the number of tics in people with TS by helping to provide a balance in the number of motor neurons (brain cells that are believed to control the tics) in the brain.

This is an open-label study, which means both the researchers and study participants know which treatment is being given. All participants will receive the NOE-105 investigational product. NOE-105 will be given to participants once a day for a maximum of 12 weeks.

Anticipated enrolment close date: 2022
