NCT03769896

Brief Summary

This is a randomized placebo-controlled, double-blind, parallel-group, enriched enrollment randomized withdrawal study assessing the efficacy and safety of nabilone for non-motor symptoms in patients with Parkinson´s Disease. Nabilone is an analogue of tetrahydrocannabinol (THC), the psychoactive component of cannabis. Nabilone acts as a partial agonist on both Cannabinoid 1 (CB1) and Cannabinoid 2 (CB2) receptor in humans and therefore mimics the effect of THC but with more predictable side effects and less euphoria. Part 1 is an open-label dose adjustment phase of the study. In eligible patients, a screening period is followed by an open-label nabilone dose optimization phase and a stable phase for at least 1 week. Treatment responders will be included in Part 2 of the study (randomized placebo-controlled, double-blind, parallel-grouped). Part 2 is the placebo-controlled, double-blind, parallel-group randomized withdrawal phase of the study.

Secondary Outcomes (21)

  • Changes in Motor and Different Non-motor Symptoms of PD

    from baseline to 4 weeks + 2 days

  • Changes in Different Domains of Non-motor Symptoms of PD

    from baseline to 4 weeks + 2 days

  • Changes in Non-motor Symptoms of PD

    from baseline to 4 weeks + 2 days

  • Changes in Non-motor Symptoms of PD

    from baseline to 4 weeks + 2 days

Eligibility Criteria

Age30 Years - 100 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥30 years
  • Diagnosis of Parkinson´s Disease (PD): PD should be either de novo or on stable medication without disturbing motor fluctuations or dyskinesia.
  • NMS with a score of ≥4 on MDS-UPDRS Part 1. One of the following domains have to be affected with a score ≥2: 1.4 (anxious mood) or 1.9 (pain)
  • On a stable regimen of anti-parkinson medications for at least 30 days prior to screening and willing to continue the same doses and regimens during study participation
  • Any other current and allowed prescription/non-prescription medications and/or nutritional supplements taken regularly must have been at a stable dose and regimen for at least 30 days prior to screening, and subject must be willing to continue the same doses and regimens during study participation
  • Patient is informed and had enough time and opportunity to think about his/her participation in the study and has signed a current Institutional Review Board-approved informed consent form
  • Contraception
  • Women of childbearing potential must use or attest an acceptable method\* of contraception starting 4 weeks prior to study drug administration and for a minimum of 1 month after study completion.
  • Men with a potentially fertile partner must be willing to use an acceptable method of contraception for the duration of the study and for 3 months after study drug discontinuation or have had a vasectomy.

You may not qualify if:

  • Patients with any of the following characteristics will be excluded from entering the study:
  • Patient previously participated in any study with nabilone.
  • Current use of cannabinoids or use of cannabinoids within 30 days prior to screening.
  • Patient is currently participating in or has participated in another study of investigational products within 30 days prior to screening.
  • Patient has any form of secondary or atypical parkinsonism (e.g., drug-induced, post stroke).
  • Patient presents with motor complications which are, based on the investigator's judgment, not adequately controlled (i.e. a score ≥2 on one of the items of the MDS-UPDRS Part IV at screening)
  • Hoehn and Yahr stage \> 3
  • Evidence of disturbing (i.e. requiring treatment) impulse control disorder in the participant. Can be resolved through a structural interview during screening period.
  • History of neurosurgical intervention for PD
  • presence of symptomatic orthostatic hypotension at screening (MDS-UPDRS 1.12 \> 2)
  • Use of prohibited medication (e.g. benzodiazepines (except for clonazepam up to a maximum of 1.5 mg per d), lithium, opioids, buspirone, muscle relaxing agents, central nervous system depressing substances, ...)
  • Patients with laboratory values that are out-of-range at Screening (or within 4 weeks prior to Screening) and haven´t been reviewed and documented as not clinically significant by the investigator. Lab Tests can be repeated for confirmation.
  • Patients with known or newly diagnosed sinus tachycardia in ECG evaluation at Screening or within 4 weeks prior to Screening.
  • presence of an acute or chronic major psychiatric disorder (e.g., Major Depressive Disorder, psychosis) or symptom (e.g., hallucinations, agitation, paranoia) (MDS-UPDRS 1.2 and/or 1.3 \> 2)
  • Patients who had a recent suicidal attempt (active, interrupted, aborted) within the past five years or report suicidal ideation within the past 6 months.
  • +9 more criteria
