E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate long-term safety and tolerability of nabilone in PD patients. |

The secondary objectives of the study are to assess the effects of long-term, open-label dosing with nabilone on different symptoms of PD and quality of life in patients with PD.
The exploratory objective of this study will be an Eye-tracking evaluation in PD patients taking nabilone at Visit V 2 to examine the change of the reaction time, attention span, and concentrativeness. |

8. History of neurosurgical intervention for PD
9. Presence of clinically significant symptomatic orthostatic hypotension at screening (MDS-UPDRS 1.12 > 2)
10. Use of prohibited medication listed in 7.4.2
11. Laboratory values clinically significant out-of-range at screening or within 4 weeks prior to screening
12. Known or diagnosed sinus tachycardia in ECG evaluation at screening or within 4 weeks prior to screening

14. recent suicidal attempt within the past five years or suicidal ideation within the past 6 months
15. presence of dementia (MDS-UPDRS 1.1 > 2, MMSE of < 24 at screening)
16. clinically significant or unstable medical or surgical condition that may preclude safe and complete study participation (based on the investigator’s judgment).
17. moderate or severe hepatic or renal impairment.
18. History of chronic alcohol or drug abuse within the last 2 years
19. women of child-bearing potential who do not practice an acceptable method of birth control [*Acceptable methods of birth control for women and men in this study are: surgical sterilization (e.g. tubal ligation for females), intrauterine devices that release hormones (hormone spiral), oral hormonal contraceptive, contraceptive patch, dermal hormonal contraception, vaginal hormonal contraception (NuvaRing®), implants that release progesterone (Implanon®), long-acting injectable contraceptive, partner’s vasectomy, a double-protection method, postmenopausal (> 2 year absence of vaginal bleeding).]

E.5 End points |
E.5.1 | Primary end point(s) |
Primary Safety and tolerability endpoints:
• Safety and tolerability will be evaluated with reference to the following:Number of subjects (%) who discontinue the study
• Number of subjects (%) who discontinue the study due to AE
• Adverse Events (AE)
• Physical and neurological examination findings
• Vital signs assessments
• Subjects compliance, prior and concomitant medication use
• Hallucination item (1.2) of Movement Disorders Society – Unified Parkinson´s Disease Rating Scale (MDS-UPDRS)
• Orthostatic hypotension (OH) item (1.12) of Movement Disorders Society – Unified Parkinson´s Disease Rating Scale (MDS-UPDRS)
• Day-time sleepiness item (1.8) of Movement Disorders Society – Unified Parkinson´s Disease Rating Scale (MDS-UPDRS) Suicidality using the Columbia-Suicide Severity Rating Scale (C-SSRS)
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary safety analysis will be performed with the safety data set including all patients with the intake of at least one study drug and performing at least V 1. A safety analysis will be performed on all events and tolerability issues, as well as the hallucination item, orthostatic hypotension item, the day-time sleepiness item of Part I of MDS-UPDRS, and C-SSRS occurring through the overall course of the study. |
|
E.5.2 | Secondary end point(s) |
Secondary Efficacy endpoints:
Long-term efficacy evaluations are the secondary objective of this study. Efficacy endpoints include changes from V 1 to the termination visit (V 4) in the following assessments:
• Total and different parts of MDS-UPDRS
• Different domains of MDS-UPDRS Part I
• NMSS
• HAD-S
• PDQ-8
• ESS
• FSS
• KPPS
• QUIP-RS
• CGI-I
The change of MMSE and MoCA score values between the Screening Visit of the NMS-Nab Study (before the first intake of nabilone medication) and the termination visit of this study will be assessed as secondary efficacy endpoints.
Exploratory Endpoints
The change of the reaction time, attention span, and concentrativeness between Screening and Termination Visit of the randomized placebo-controlled, double-blind, parallel-group, enriched enrolment randomized withdrawal study NMS-Nab and V 2 of this study as measured by the Eye-tracking examination will be an exploratory endpoint. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The secondary efficacy criterion will be measured as the change of all assessments between V 1 and month 6, except for the MoCA and MMSE (will be compared between the Screening visit of the precursory NMS-Nab study and the Termination Visit of this study).
The exploratory end point will be measured at V 2 of this study and compared to the Screening and Termination Visit of the precursory NMS-Nab Study. |
