Obsessive Compulsive Disorder

Reimbursement: £490 plus reasonable travel costs

About This clinical research study

MAC Clinical Research is testing a new medication for OCD. OCD means Obsessive Compulsive Disorder. OCD is a mental health condition which causes uncontrolled intrusive or obsessive thoughts which may then lead to time consuming compulsive behaviours (such as checking, cleaning, counting and other rituals) to neutralise the thoughts.

People with OCD tend to have signalling pathways in the brain which are overactive, called the glutamatergic pathways.  The drug used in the study, troriluzole, works to dampen down these overactive pathways (called the glutamatergic signalling pathway) which may help people with OCD when used in combination with your usual OCD medication.

To be eligible to take part in this study you must have been diagnosed with OCD, or have had symptoms of OCD for at least a year and be taking medication that you do not feel is fully helping with your condition.  You will have to agree to carry on taking your usual medication throughout the study.  Further restrictions may apply depending on your medical history.

Upon completion of the study participants will be offered an opportunity to enter the Open Label Extension and receive the medication free of charge for 1 year.

A full description of the study will be given before you decide to take part, both over the phone and during an appointment at the MAC clinic. This will include you receiving the full patient information sheet (PIS). Your GP will also be notified of your participation.

If you contact us, it does not mean you have to decide at that point whether to participate.
If you do decide to participate you are free to withdraw at any time.

The study will run for approximately five months.  This includes taking the medication daily for ten weeks, and requires 7visits to the clinic for check-ups to see: 

  • If your OCD symptoms improve.
  • How well you cope with taking the medication (any side-effects).

Clinical research studies are performed as a way of bringing about progress in medicine and research. Clinical research studies make it possible to scientifically assess the properties of a drug, to demonstrate the effectiveness and safety of a treatment or a medical device, or to learn more about a disease and methods to diagnose and monitor it.

If the study is successful, it may be an important step towards developing a promising new treatment.
