Propofol + Therapy for Depression
(SWIPED II Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether combining brief therapy with propofol (a medication often used for anesthesia) can improve sleep and mental health in older adults with depression. Researchers aim to determine if different doses of propofol, administered a few days apart, affect sleep patterns and mood. Participants will also attend therapy sessions designed to improve insomnia. This trial may suit individuals aged 60 or older who have not found relief from depression with standard antidepressant pills. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.
Do I need to stop taking my current medications for the trial?
You may need to stop or adjust some medications to participate in the trial. Specifically, you cannot use benzodiazepines over 2 mg/day, trazodone over 50 mg/day, or gabapentin over 600 mg/day. If you are taking these medications, you should discuss with the trial team about any necessary changes.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that propofol, a common anesthesia drug, is generally safe for treating depression. A recent study tested deep propofol anesthesia on adults with depression unresponsive to other treatments. The results indicated it was feasible and well-tolerated by these physically healthy individuals. This suggests that propofol can be safely managed under medical supervision for people with depression.
When compared to other treatments like esketamine, propofol had a slightly lower success rate in improving depression symptoms. However, this difference pertains to effectiveness, not safety. The main point is that studies have used propofol safely in depressed patients, with no major safety issues reported.12345Why are researchers excited about this trial's treatments?
Researchers are excited about using propofol to treat depression because it works in a completely different way than traditional antidepressants. Most antidepressants target neurotransmitter levels like serotonin, but propofol is an anesthetic that induces brain states similar to deep sleep or unconsciousness, potentially resetting brain activity patterns associated with depression. Additionally, while standard antidepressants can take weeks to show effects, propofol could offer rapid relief after just a few infusions. This approach could be a game-changer for patients who haven’t responded well to conventional treatments.
What evidence suggests that this trial's treatments could be effective for depression?
Research has shown that propofol, a common anesthetic, might quickly and effectively reduce depression symptoms. Studies have found that propofol can help people with depression who haven't improved with other treatments. In one study, about 60% of participants experienced significant relief from their depression symptoms after receiving propofol. Researchers believe that propofol helps by improving deep sleep, which is important for mood balance. In this trial, participants will receive either a moderate dose or a low dose of propofol. Both dosing strategies proved effective in previous studies, and the treatment is generally well tolerated. These findings suggest that propofol could be a promising option for improving mood in people with depression.16789

Are You a Good Fit for This Trial?
This trial is for older adults with depression. Participants must be able to undergo propofol infusions and brief behavioral therapy for insomnia. There are no gender or ethnic restrictions, but other specific inclusion and exclusion criteria have not been provided.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Behavioral Therapy
Two sessions of Brief Behavioral Therapy for Insomnia (BBTI) are administered before the propofol infusions
Treatment
Participants receive two propofol infusions, 2-6 days apart, with concurrent EEG monitoring
Post-Treatment Behavioral Therapy
Two additional sessions of BBTI are administered within 6 weeks after the second infusion
Follow-up
Participants are monitored for changes in sleep structure, cognition, anhedonia, and depression up to 10 weeks after the second infusion
What Are the Treatments Tested in This Trial?
Interventions
- Propofol
Trial Overview
The SWIPED Stage II trial tests if low or moderate doses of propofol can improve sleep and mental health in depressed elderly patients when combined with sleep-focused therapy. It's a double-blind study where participants won't know which dose they receive.

Experimental Treatment
Active Control
Serial propofol infusions to maximally and safely induce unconsciousness and EEG slow waves while minimizing burst suppression. Target brain effect-site concentrations \>2.5 mcg/ml. This will be paired with BBTI.
