What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment called Low Intensity Focused Ultrasound (LIFU) for people with OCD who haven't responded to usual treatments. LIFU uses sound waves to stimulate a specific brain area, aiming to improve symptoms. The study will observe changes in brain activity and OCD symptoms over a short period of treatment.

Will I have to stop taking my current medications?

No, you will not have to stop taking your current medications. Participants must stay on their SRI medications at a stable dose for at least 2 months before and during the trial.

Is Low-Intensity Focused Ultrasound (LIFU) safe for humans?

Low-Intensity Focused Ultrasound (LIFU) is a new technique that shows promise for safely targeting deep brain areas without surgery. It is considered noninvasive and reversible, which suggests it may be safer than traditional surgical methods, but more research is needed to confirm its safety in humans.12345

What data supports the effectiveness of the treatment BX Pulsar 1002 for OCD?

The research on high-intensity focused ultrasound (HIFU), a similar technology to LIFU, shows it is effective and safe for treating various conditions like prostate issues, glaucoma, and tumors. This suggests that LIFU might also be effective for OCD, although direct evidence for OCD is not provided.678910

Are You a Good Fit for This Trial?

This trial is for adults aged 21-55 with a main diagnosis of OCD lasting over 2 years. They must have tried at least two types of SSRIs or one SSRI and clomipramine without success, and if on medication, it should be stable for 2 months before the study. Women must use contraception, and participants can't have had more than four failed SSRI/clomipramine treatments.

What Are the Treatments Tested in This Trial?

Interventions

  • BX Pulsar 1002
Trial Overview The trial tests Low Intensity Focused Ultrasound (LIFU) using BX Pulsar 1002 to stimulate the brain's Ventral Striatum region in patients with OCD. It's non-invasive and paired with MRI scans to observe changes in brain activity related to OCD symptoms during six sessions over two weeks.

Published Research Related to This Trial

Low-intensity focused ultrasound (LIFU) is a promising noninvasive technique for neuromodulation that could improve treatment outcomes for patients with Major Depressive Disorder (MDD) and Obsessive-Compulsive Disorder (OCD) who do not respond to traditional therapies.
Current psychosurgical techniques, such as deep-brain stimulation, have variable success rates, with only about half of patients showing adequate response, highlighting the need for innovative approaches like LIFU to enhance personalized treatment strategies.
