About this trial
The primary goal of this study is to test the hypothesis that oral nabilone treatment will reduce agitation compared with placebo in patients with Frontotemporal Dementia (both behavioural variant frontotemporal dementia and primary progressive aphasia). The study population is defined as patients with probable Frontotemporal Dementia that meet the International Psychogeriatric Association criteria for agitation in cognitive disorders.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Men and women over 18 years
Major neurocognitive disorder due to probable behavioural variant FTD (Rascovsky criteria)17 or primary progressive aphasia (Gorno-Tempini criteria)18. All ages and severity levels will be included.
Meets International Psychogeriatric Association criteria for agitation in cognitive disorders19
CMAI score of 39 or above
Disqualifiers
Clinically significant psychotic symptoms (Neuropsychiatric Inventory domain score (severity x frequency) ≥4 on the delusions or hallucinations subscale)
Clinically significant orthostatic hypotension (a decrease in systolic blood pressure of 20 mm Hg or in diastolic blood pressure of 10 mm Hg within three minutes of standing compared to blood pressure in a seated position)
Symptomatic orthostatic tachycardia (heart rate increase from of at least 30 beats per minute within the first 5 minutes of standing compared to a seated position IF orthostatic hypotension is not a problem)
Unstable cardiovascular condition in the opinion of the investigator
Trial design
Crossover
Treatments tested in this trial
Nabilone
DrugNabilone is a synthetic cannabinoid that has shown benefit for agitation in Alzheimer's disease. Nabilone further has potentially beneficial properties on oxidative stress and inflammation in neurodegenerative diseases, mechanisms that have been linked to the pathophysiology of frontotemporal dementia.
Placebo
DrugThe placebo is a capsule identical to the nabilone capsules that will be used in this clinical trial.
Treatment groups
Trial outcomes
Primary outcomes
Cohen Mansfield Agitation Inventory (CMAI)
A scale that is completed by a caregiver with at lest 10 hours of weekly contact with the patient. This scale evaluates a range of symptoms that fall into the category of agitation.
Secondary outcomes
Tumor necrosis factor alpha (TNFα)
Examine the relationship between TNFα and CMAI scores at baseline and following nabilone treatment.
4-hydroxynonenal (4-HNE)
Examine the relationship between 4-HNE and CMAI scores at baseline and following nabilone treatment.
Other outcomes
Adverse drug reaction (ADR) to varying doses of nabilone
Quantify the prevalence of ADR that occur in response to varying doses of nabilone treatment in patients diagnosed with Frontotemporal Dementia.
