Brief Summary

Full Title: A phase II, randomized, open-label, double-blind, two-center study to evaluate the tolerability, safety and dose-finding of oil cannabis preparation for pain in Parkinson's disease. Short title: Cannabis oil for pain in Parkinson's disease Sample Size: N = 15 Study Population: Patients with Parkinson's disease and pain, without cognitive impairment. Study Duration: July 2018 - July 2019 Study Agent/ Intervention: Cannabis oil: mixed oil cannabis preparation consisting of 3 different formulations of ∆-9THC and cannabidiol - 18:0; 10:10; and 1:20 respectively. Cannabis oil will be administered orally once per day, as required for pain; or taken 4h before bedtime, if no pain. Primary objective: to determine the safety and tolerability of different formulations of Cannabis oil for pain in PD patients (incidence and severity of adverse events). Secondary objective: to assess change from the start of treatment (V2) to end of treatment (V5) in frequency and severity of pain, sleep, dystonia and motor symptoms in PD patients.

Outcome Measures

Primary Outcomes (2)

  • Maximum tolerated dose (MTD) in each individual

    MTD will be defined as the dose of each CanniMed® preparation for which the subject was able to be on for a minimum of 1 week, without the occurrence of an AE or suspected AE, with the severity grading of 2 or higher (CTCAE v.4.0)

    From baseline (Visit 1) to end of study (Visit 5); total 35 days of intervention.

  • Treatment-emergent adverse events (safety)

    Determine the incidence and severity of adverse events by direct patient questioning, physical examination and ancillary testing as per protocol

    From baseline (Visit 1) to end of study (Visit 5); total 35 days of intervention.

Secondary Outcomes (1)

  • Collect the King's Parkinson Disease Pain scale (KPPS) scores in the intervention group, adjusted for baseline scores.

    From baseline (Visit 1) to Follow-up phone call (1 week after Visit 5); Total 35 days

Other Outcomes (5)

  • Changes in the Visual Analogue Scale for Pain (adjusted for baseline scores)

    From baseline (Visit 1) to end of study (Visit 5); total 35 days.

  • Changes in the MDS-UPDRS part III (adjusted for baseline scores)

    From baseline (Visit 1) to end of study (Visit 5); total 35 days.

  • Changes in the UDysRS - Dystonia part 2 subscores (adjusted for baseline)

    From baseline (Visit 1) to end of study (Visit 5); total 35 days.

Interventions

Mixed oil cannabis preparation consisting of 3 differing formulations of ∆-9THC and CBD is clinically available in Canada as CanniMed®. The 3 differing formulations of CanniMed® oils contain varying proportions of ∆-9THC and CBD in the following ratios: 18:0; 10:10; 1:20. All CanniMed® oil formulations consist of cannabinoids extracted from dried cannabis, and diluted in olive oil.

Masking Details
This will be a double-blind study. The different cannabis oil formulations have the same colour, taste and smell. Study investigators will be blind to the dose/formulation of cannabis oil. Unblinding will only be performed in the event of a Serious AE. The site PI will maintain a randomization list kept in a locked secure 24h a day accessible location for emergency unblinding.
