Opiate Suicide Study in Patients with Major Depression

We are doing this study to determine if suicidal thoughts are lessened after an infusion of ketamine followed by 4 weeks of a medication called buprenorphine. Participants for this research will be currently experiencing depression and will have not responded to treatment with antidepressants or have an intolerance to these types of medicines. Recent studies have shown a single infusion of ketamine to reduce suicidal ideation within 24 hours and to last for at least one week.  We would like to determine if a single infusion of ketamine followed by 4 weeks of low dose burprenorphine produces longer lasting anti-suicidal effects than does ketamine followed by placebo.

This research study is expected to take approximately 2 years to complete with at least 6 weeks of active participation by each participant.  During this time, participants will make 10 study visits to Stanford University, including an 8-hour infusion visit.

Under the close supervision and monitoring by the study clinicians, eligible subjects will receive a single infusion of ketamine 0.5mg/kg followed by oral buprenorphine or placebo for 4 weeks.

This research study will use either Buprenorphine or a placebo, containing no drug, to study if the benefits experienced from Ketamine can be improved or last longer when buprenorphine is taken for 4 weeks.

Neuroimaging Biomarkers for Predicting rTMS Response in OCD


We are doing this research study to find if a new form of Repetitive transcranial magnetic stimulation (rTMS) is an effective in treating OCD. So far, at least two stimulation targets have consistent evidence of efficacy in OCD: the dorsomedial prefrontal cortex (DMPFC) and the orbitofrontal cortex (OFC). Patients often show a strong response to one target but not the other. It is not well understood why some patients respond, while others do not. So far, there are no biomarkers for predicting treatment response, identifying the optimal neuroanatomical target, or choosing between treatments.


This study evaluates an accelerated schedule of theta-burst stimulation using a Transcranial Magnetic Stimulation (TMS) device for treatment-resistant Obsessive Compulsive Disorder (OCD). In a randomized fashion, half the participants will receive accelerated theta-burst stimulation at the dorsomedial prefrontal cortex (DMPFC), while half will receive accelerated theta-burst stimulation at the right orbitofrontal (rOFC) site.

Bilateral Accelerated Theta Burst in Treatment-Resistant Bipolar Depression: A Biomarker Study

We are doing this research study to find out if a new form of repetitive transcranial magnetic stimulation (rTMS) is effective in treating treatment-resistant bipolar depression. rTMS is approved by the U.S. Food and Drug Administration (FDA) for the treatment of MDD in adults with depression that have not benefited from medication. This FDA-approved treatment involves stimulating the left frontal area of the head with an electromagnet that produces a magnetic field delivered in short bursts. These bursts are focused on an area of the brain that is thought to be involved in causing depression. As the magnet rapidly turns on and off, the electrical currents in the brain tend to synchronize with the magnet. TMS has been shown to help some patients with depression.

In this study, we are looking at a new way of using intermittent TBS to treat treatment-resistant bipolar depression.  The name of this new procedure is “accelerated intermittent theta-burst stimulation (aiTBS)”.  aiTBS involves using shorter periods of stimulation over multiple treatments received each day for five days.  We hope to learn if this shorter type of TMS is effective in treating bipolar depression. This open-label pilot study will be conducted with 30 patients who will receive active aiTBS treatment.

If you have been diagnosed with treatment-resistant depression and are interested in participating, please fill out our survey to see if you qualify. This is a multi-step screening process.
