Study Arms (2)
Nabilone 0.5mg
EXPERIMENTALSubjects will receive nabilone 0.5 mg orally at night for 1 week increased to nabilone 0.5mg orally twice a day for 3 weeks (over-encapsulated). Drug will be dispensed from a central site to other sites and pharmacy personnel will dispense the study medications directly to research personnel or participants. Drug dispensation will coincide with study visits at randomization and crossover and will allow research personnel to reinforced adherence. The study oral medications may be taken at any time of day with food or water, but we will request that participants take it at the same time each day, preferably at night when uremic pruritus symptoms are usually at the worst. If participants have any side effects or intolerability to study drugs, they may decrease the frequency of nabilone or placebo to 1 capsule by mouth once daily, preferably taken at night.
Oral placebo
PLACEBO COMPARATORSubjects will receive placebo 1 capsule orally at night for 1 week increased to placebo 2 capsules twice a day for 3 weeks (over-encapsulated). Drug will be dispensed from a central site to other sites and pharmacy personnel will dispense the study medications directly to research personnel or participants. Drug dispensation will coincide with study visits at randomization and crossover and will allow research personnel to reinforced adherence. The study oral medications may be taken at any time of day with food or water, but we will request that participants take it at the same time each day, preferably at night when uremic pruritus symptoms are usually at the worst. If participants have any side effects or intolerability to study drugs, they may decrease the frequency of nabilone or placebo to 1 capsule by mouth once daily, preferably taken at night.
Interventions
This intervention will consist of subjects receiving nabilone 0.5 mg orally at night for 1 week increased to nabilone 0.5mg orally twice a day for 3 weeks. Duration of the intervention will be 4 weeks.
This intervention will consist of subjects receiving placebo 1 capsule orally at night for 1 week increased to placebo 2 capsules twice a day for 3 weeks. Duration of the intervention will be 4 weeks.
Eligibility Criteria
You may qualify if:
- Age\>25 years
- In-center or home hemodialysis at least two times weekly or peritoneal dialysis at least once daily for \>90 days
- Generalized uremic pruritus with a mean worst VAS\>40mm over the previous week (with at least 5/7 patient diary days completed)
- ALT less or equal to 3x upper limit of normal and bilirubin less than or equal to 2x upper limit of normal in the last 90 days
- Able to provide informed consent and complete patient reported outcome measurements without a language barrier or cognitive impairment
You may not qualify if:
- Etiology of pruritus (in the opinion of the treating physician) thought to be secondary to primary dermatologic condition, liver disease, hematologic malignancy or allergy
- Use of recreational or medical cannabis in the last 4 weeks (THC, CBD, nabilone, Sativex, Epidiolex)
- Women of childbearing potential as assessed by their clinician regardless of abstinence from sex or the use of contraception
- Planned kidney transplantation, travel or relocation in the next 3 months
- Unstable psychiatric illness (the presence of a lifetime diagnosis of a psychotic disorder, bipolar disorder, substance use disorder or current suicidal ideation)
- Symptomatic hypotension in the last 2 weeks defined as a systolic blood pressure (SBP) less than 90mmHg during or in between dialysis requiring an intervention (i.e. administration of crystalloid or colloid, termination of dialysis, change in pharmacologic therapy such as withdrawal of anti-hypertensive therapy or initiation/titration of midodrine, increase in dry weight)
- History of hypersensitivity to any cannabinoid
- Presence of any clinically significant or unstable medical conditions, including cardiovascular, liver, pulmonary disease
