What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how cannabinoids (compounds found in cannabis) might assist veterans with PTSD and suicidal thoughts. Participants will be divided into groups receiving different cannabis treatments: one with THC (Tetrahydrocannabinol), one with CBD (Cannabidiol), and one with both. The goal is to determine if these treatments can relieve PTSD symptoms. Veterans who have used cannabis in the past year and have PTSD might be suitable candidates for this study. As a Phase 1/Phase 2 trial, this research aims to understand how the treatment works in people and measure its effectiveness in an initial, smaller group.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, you cannot participate if you test positive for drugs other than cannabis, nicotine, or mild to moderate alcohol use.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that cannabis, including THC (tetrahydrocannabinol) and CBD (cannabidiol), has been studied for managing PTSD symptoms. Studies have found that THC is generally well-tolerated, with some people experiencing mild side effects like dry mouth and headaches. CBD has also been tested and appears safe to use, with no major issues reported in early studies.

Evidence suggests that using THC and CBD together can help reduce PTSD symptoms. Research on this combination has not commonly reported any severe side effects.

Overall, both THC and CBD are considered to have a reasonable safety profile based on previous research, but individual reactions can vary. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they explore the potential of cannabis components, cannabidiol (CBD) and tetrahydrocannabinol (THC), to address PTSD in veterans. Unlike traditional PTSD treatments, which often involve antidepressants and therapy, these treatments use active ingredients derived from cannabis, which may interact with the body’s endocannabinoid system to potentially reduce anxiety and stress. The study also investigates different combinations of THC and CBD, providing unique insights into how these compounds might individually or synergistically benefit those with PTSD.

What evidence suggests that this trial's treatments could be effective for PTSD in veterans?

This trial will compare different cannabis treatments for PTSD in veterans. Research has shown that cannabis, which includes THC and CBD, may help reduce PTSD symptoms. Participants in this trial may receive THC, which several studies have found can improve sleep and lessen PTSD symptoms in veterans. Others may receive CBD; one study showed that 91% of patients reported less severe PTSD symptoms after just eight weeks. Some participants will receive a combination of THC and CBD, which might greatly improve anxiety and ease social activities. Overall, these findings suggest that cannabis could be a helpful option for managing PTSD symptoms. ^{1 3 6 7 8}

Cannabis with 5 mg THC; up to a maximum of 5 doses/day (max dose = 25 mg THC)

Group II: THC & CBD Group Experimental Treatment 2 Interventions

Cannabis with 5 mg THC and 5 mg CBD; up to a maximum of 5 doses/day (max doses = 25 mg THC and 25 mg CBD)

Group III: CBD Group Experimental Treatment 1 Intervention

Cannabis with 5 mg CBD; up to a maximum of 5 doses/day (max dose = 25 mg CBD)

Group IV: Placebo Group Active Control 1 Intervention

Cannabis with \<1mg THC and \<1mg CBD; up to a maximum of 5 doses/day (max dose = \<5 mg THC and \<5 mg CBD)

In a study involving 27 healthy volunteers, a single clinically anxiolytic dose of 300 mg of CBD did not significantly affect the sleep-wake cycle, indicating it does not interfere with normal sleep architecture.

Unlike traditional anxiolytic medications, CBD appears to maintain the natural sleep patterns of individuals, suggesting it may be a safer alternative for anxiety management without disrupting sleep.

No Acute Effects of Cannabidiol on the Sleep-Wake Cycle of Healthy Subjects: A Randomized, Double-Blind, Placebo-Controlled, Crossover Study. Linares, IMP., Guimaraes, FS., Eckeli, A., et al.[2020]

Cannabidiol (CBD) shows promise as a therapeutic option for treating COVID-19-related anxiety and post-traumatic stress symptoms, supported by small randomized controlled trials that demonstrate its anxiolytic effects in various populations.

Pre-clinical studies indicate that CBD interacts with specific receptors in the brain, such as cannabinoid receptors and serotonin receptors, which may help reduce anxiety and improve sleep quality, making it a potential candidate for further investigation in larger clinical trials.

Could Cannabidiol Be a Treatment for Coronavirus Disease-19-Related Anxiety Disorders? O'Sullivan, SE., Stevenson, CW., Laviolette, SR.[2022]

A systematic review of 4186 studies on cannabidiol (CBD) revealed that most research focuses on neurological outcomes, with significant adverse events reported in this area, highlighting the need for careful assessment of CBD's safety.

There is a notable gap in research regarding the reproductive and developmental toxicity of CBD, suggesting that future studies should prioritize these areas to establish safe intake levels for consumers.

In a study of 198 participants with anxiety disorders, treatment with various cannabis formulations significantly improved quality of life outcomes, including reductions in anxiety, depression, and fatigue, as well as enhanced social functioning.

Common adverse events reported included dry mouth, somnolence, and fatigue, with gastrointestinal issues more prevalent in formulations containing THC, indicating a need for careful consideration of cannabis formulation in treatment.

In a study of 11 adults with PTSD, 91% experienced a reduction in symptoms after 8 weeks of oral CBD treatment, with an average decrease in PTSD Checklist scores of 28%.

CBD was well tolerated by patients, with no discontinuations due to side effects, suggesting it may be a safe adjunct treatment for PTSD alongside standard psychiatric care.

This study is the first placebo-controlled clinical trial examining the efficacy of cannabidiol (CBD) for treating PTSD, involving 150 participants over an 8-week period.

The trial compares the effects of two types of CBD (Isolate and Broad Spectrum) on PTSD symptoms, with outcomes measured using the PTSD Checklist for DSM-5, aiming to assess both efficacy and safety.

A systematic review of 10 studies suggests that medicinal cannabinoids like CBD, Δ9-THC, and nabilone may improve overall PTSD symptoms and specific issues such as sleep disorders and arousal disturbances, potentially enhancing quality of life.

While the results are promising for using cannabinoids as a treatment for PTSD, more research is necessary to fully understand the safety and long-term efficacy of these treatments.

In a mouse model of PTSD, cannabidiol (CBD) significantly reduced PTSD-like symptoms by affecting trauma-related fear memory and anxiety behaviors, showing its potential as a treatment option.

Unlike the antidepressant sertraline, which was only effective when given before exposure to fear, CBD was effective regardless of when it was administered, indicating a broader mechanism of action in fear memory processing.

In a study of 33 PTSD patients, administering 300 mg of cannabidiol (CBD) before recalling a nonsexual traumatic event significantly reduced anxiety and cognitive impairment compared to a placebo.

However, CBD did not show a significant effect on anxiety or cognitive impairment in patients recalling sexual trauma, suggesting that the efficacy of CBD may depend on the nature of the traumatic event.
