Patient information sheet


Early stage Parkinson's disease


Subjects will be randomised to receive either BIIB014 or placebo orally in one of the following sequentially enrolled cohorts:
Cohort 1: 8 subjects receive 10 mg BIIB014 and 2 subjects receive placebo for a total of 8 weeks
Cohort 2: 8 subjects receive 30 mg BIIB014 and 2 subjects receive placebo for a total of 8 weeks
Cohort 3: 8 subjects receive 30 mg BIIB014 for 1 week, followed by 100 mg of BIIB014 for 7 weeks; 2 subjects receive placebo
Cohort 4: 8 subjects receive 100 mg BIIB014 and 2 subjects receive placebo for a total of 8 weeks

No maximum tolerated dose was identified in Phase 1. An alternative 50 mg BIIB014 dose may be explored if 100 mg BIIB014 in Cohort 3 is not tolerated.

Intervention type

Drug names


Primary outcome measures

To assess the preliminary safety and tolerability of multiple oral doses of BIIB014 when administered to subjects with early-stage PD, carried out throughout the study.

Secondary outcome measures

1.To estimate pharmacokinetic (PK) parameters of BIIB014 and its N-acetyl metabolite in subjects with early-stage PD, carried out throughout the study
2.To explore the activity of BIIB014 when administered to subjects with early-stage PD. This will be assessed by the Unified Parkinson's Disease Rating Scale (UPDRS) throughout the study, and the Hoehn and Yahr staging at days 8, 15, 29, 43, 57 and 71 and the Clinical Global Impression scale (CGI) at days 29, 57 and 71.

Participant inclusion criteria

1. Must give written informed consent and any authorisations required by local law
2. Must be 30 years or older at the time of informed consent
3. Must carry a diagnosis of idiopathic Parkinson’s disease, without any other known or suspected cause of parkinsonism, according to the UK Parkinson’s Disease Society Brain Bank Clinical Diagnostic Criteria. Initial diagnosis of PD must have been made within the 5 years prior to Screening with at least two or more of the following cardinal signs being present: bradykinesia, resting tremor, rigidity, and postural instability.
4. Must be Modified Hoehn and Yahr Stage 1 to 2.5 inclusive
5. Must have a Unified Parkinson's Disease Rating Scale (UPDRS) motor score (Part III) of greater or equal to 10
6. For subjects receiving an anticholinergic agent and/or MAO-B inhibitor, must have been on a stable dose of that medication for at least 4 weeks prior to Day 1. Subjects must be willing and able to maintain this dosing regimen throughout their participation in the study and must be willing and able to refrain from any other PD medication throughout their participation in the study.
7. Male and female subjects of child-bearing potential must be willing to practice effective birth control for the duration of the study. Female subjects must be one of the following:
7.1. Postmenopausal for at least 12 months, as confirmed by the patient's Obstetrician/Gynecologist (OB/GYN) or medical records
7.2. Surgically sterile (i.e., no uterus or no ovaries; females who have tubal ligation [tubes tied or cut] are not considered surgically sterile)
7.3. Willing to use 2 acceptable forms of birth control (i.e., barrier and spermicide, intrauterine device and barrier or spermicide, or birth control pill and barrier or spermicide). Male subjects with partners of child-bearing potential must use barrier contraception in addition to a second method of contraception used by their female partners. Male subjects should be advised to abstain from sexual intercourse with pregnant women or use condoms. Male and female subjects must be willing and able to continue contraception for 2 months after their last dose of study treatment. Female subjects of childbearing potential must have a negative pregnancy test result at both the Screening Visit and the Day 1 Visit.
