Trial Summary
What is the purpose of this trial?This is a multicenter randomized double-blind placebo-controlled Phase 2 study of an oral combination of tetrahydrocannabinol (THC) and cannabidiol (CBD) compared to placebo over 12 weeks. This study is designed to test the hypothesis that treatment with an oral combination of THC/CBD will reduce agitation hospice care-eligible patients with agitation and dementia as measured by the Cohen Mansfield Agitation Inventory (CMAI) when compared to placebo at 2 weeks.
This study will enroll approximately 150 participants of any gender at least 40 years of age who are hospice care-eligible with agitation and dementia (HAD). Participants will be randomized (50:50) to either active study drug (T2:C100) or placebo.
The double-blind period of this study is 12 weeks. A 12 week optional open-label extension will be offered to participants who complete the double-blind period.
Is the drug CBD + THC a promising treatment for agitation in dementia?Yes, CBD and THC together show promise as a treatment for agitation in dementia. They have been found to be effective and safe, with fewer side effects compared to other medications used for dementia-related behaviors. This makes them a potentially better option for managing symptoms like agitation in older patients with dementia.23467
What data supports the idea that CBD + THC for Agitation in Dementia is an effective treatment?The available research shows that using CBD and THC together may help reduce agitation in people with dementia. One study found that cannabinoids, which include THC and CBD, were effective and safe for older people with dementia-related agitation, with fewer short-term side effects compared to other medications. Another study is testing a specific THC product called dronabinol to see if it helps with agitation in Alzheimer's patients. While more research is needed, these studies suggest that CBD and THC could be a promising option for managing agitation in dementia.14567
What safety data exists for CBD and THC in treating agitation in dementia?Studies suggest that cannabinoids, including THC and CBD, are generally well tolerated with few short-term side effects when used for agitation in dementia. A 2017 review found positive therapeutic benefits, though results varied due to different cannabinoid products. Further research is needed to confirm safety and efficacy. Additionally, a trial of dronabinol (synthetic THC) is ongoing to assess its safety and efficacy for agitation in Alzheimer's dementia.23457
Do I have to stop taking my current medications to join the trial?The trial protocol does not specify if you need to stop taking your current medications. However, you must not use any cannabinoids other than the trial medication during the first 12 weeks.
Eligibility Criteria
This trial is for hospice care-eligible patients aged 40 or older with dementia and significant agitation.

My condition is at stage 6d of the FAST scale.
I can take medicine in liquid form.
Exclusion Criteria
I am not allergic to cannabinoids or oils like coconut or sesame oil.
Treatment Details
The trial tests an oral mix of THC/CBD against a placebo over 12 weeks to see if it reduces agitation in dementia patients. Participants are randomly assigned to either the drug or placebo group in equal numbers.

Use of Cannabis for Agitation in Patients With Dementia. [2021]Studies have reported changes in the endocannabinoid system in the brain of patients with Alzheimer's disease (AD), playing a role in the pathophysiology of AD. Cannabinoids have been shown to have neuroprotective properties, reduce neuroinflammation, and enhance neurogenesis. Evidence suggests that the utilization of marijuana products containing both tetrahydrocannabinol (THC) and cannabidiol (CBD) or CBD alone have been effective and safe for use in older people with agitation associated with dementia. A review in 2017 summarized positive findings for therapeutic benefits of cannabinoids in agitation of AD and dementia, but there was no definitive conclusion because of varying cannabinoid products. Cannabinoids were shown to be well tolerated, with few short-term side effects. This differs from first-line medications utilized for dementia behaviors, which can have unwanted side effects. Further research regarding the safety, efficacy, and variability of these products in older people is needed.
Study rationale and baseline data for pilot trial of dronabinol adjunctive treatment of agitation in Alzheimer's dementia (THC-AD). [2022]Agitation is a common complication of Alzheimer's dementia (Agit-AD) associated with substantial morbidity, high healthcare service utilization, and adverse emotional and physical impact on care partners. There are currently no FDA-approved pharmacological treatments for Agit-AD. We present the study design and baseline data for an ongoing multisite, three-week, double-blind, placebo-controlled, randomized clinical trial of dronabinol (synthetic tetrahydrocannabinol [THC]), titrated to a dose of 10 mg daily, in 80 participants to examine the safety and efficacy of dronabinol as an adjunctive treatment for Agit-AD. Preliminary findings for 44 participants enrolled thus far show a predominately female, white sample with advanced cognitive impairment (Mini Mental Status Examination mean 7.8) and agitation (Neuropsychiatric Inventory-Clinician Agitation subscale mean 14.1). Adjustments to study design in light of the COVID-19 pandemic are described. Findings from this study will provide guidance for the clinical utility of dronabinol for Agit-AD.

NAbiximols Clinical Translation To the treatment of Pain and Agitation In Severe Dementia (NACTOPAISD): Clinical trial protocol. [2022]Up to 80 % nursing home residents with dementia experiences chronic pain. Contextually, 97 % presents fluctuant neuropsychiatric symptoms (NPS). Among the most challenging is agitation, connected with undertreated pain and managed through neuroleptics doubling death risk. Evidence is accumulating in favor of the involvement of the endocannabinoid system in nociception and NPS. This double-blind, placebo-controlled, randomized trial (NAbiximols Clinical Translation To the treatment of Pain and Agitation In Severe Dementia [NACTOPAISD]) aims at investigating efficacy and safety of oral spray nabiximols, containing ฮ9-tetrahydrocannabinol and cannabidiol (Sativexยฎ), for pain and agitation treatment in severe dementia patients (Mini-Mental State Examination โค 12) over 65. The coprimary endpoints are efficacy on pain and agitation, assessed through the recently validated Italian Mobilization-Observation-Behavior-Intensity-Dementia and the Cohen-Mansfield Agitation Inventory. The secondary endpoint is the evaluation of efficacy duration after wash-out and the assessment of quality of life through the DEMQOL. Any adverse events will be reported. The results undergo statistical analysis plan. NACTOPAISD might provide rationale for a translational safer pain and agitation treatment in severe dementia. It is approved by Calabria Region Ethics Committee and follows the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) and the Consolidated Standards of Reporting Trials (CONSORT) statements.
Oral THC: CBD cannabis extract in main symptoms of Alzheimer disease: agitation and weight loss. [2023]Ten million new cases of dementia are recorded annually worldwide, with agitation and idiopathic weight loss being the most common symptoms. Several pharmacological therapies have emerged in recent years, but the clinical use of cannabis extracts in older patients with AD is constantly growing. This retrospective, analytical, observational, spontaneous trial aimed to enhance the clinical action of THC: CBD cannabis extract administration in AD patients with severe symptoms such as agitation, weight loss, cognitive impairment, and sleep disturbance.
