Study Description

Brief Summary:

This multicenter, randomized, double-blind, placebo-controlled, Phase 2 study will evaluate the efficacy of intravenous prasinezumab (RO7046015/PRX002) versus placebo over 52 weeks in participants with early Parkinson's Disease (PD) who are untreated or treated with monoamine oxidase B (MAO-B) inhibitors since baseline. The study will consist of three parts: a 52-week, double-blind, placebo-controlled treatment period (Part 1) after which eligible participants will continue into an all-participants-on-treatment blinded dose extension for an additional 52 weeks (Part 2). Participants who complete Part 2 (including the 12-week treatment-free follow up visit assessing long term safety and efficacy of RO7046015) will be offered participation in Part 3 open-label extension (all-participants-on-RO7046015-treatment) for an additional 260 weeks.

Outcome Measures

Primary Outcome Measures :

1. Change From Baseline in Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Total Score (Sum of Parts I, II, and III) at Week 52 [ Time Frame: From baseline to Week 52 ]
   The MDS-UPDRS is a multimodal scale consisting of four parts. Part I assessed non-motor experiences of daily living and has 2 components (Range 0-52). Part IA contains 6 questions and are assessed by the examiner (Range 0-24). Part IB contains 7 questions on non-motor experiences of daily living which was completed by the participant (Range 0-28). Part II assessed motor experiences of daily living (Range 0-52). It contained 13 questions completed by the participant. Part III assessed the motor signs of Parkinson's Disease (PD) and was administered by the rater (Range 0-132). Part III contained 33 scores based on 18 items. For each question a numeric score is assigned between 0-4, where 0 = Normal, 1 = Slight, 2 = Mild, 3 = Moderate, 4 = Severe. The MDS-UPDRS Total Score equals the sum of Parts I,II, and III (Range: 0-236). A higher score indicated more severe symptoms of Parkinson's disease.

Secondary Outcome Measures :

1. Change From Baseline in the MDS-UPDRS Part IA, Part IB, Part I Total, Part II Total, Part III Total and Part III Subscores [ Time Frame: From baseline to Week 52 ]
   The MDS-UPDRS is a multimodal scale consisting of four parts. Part I assessed non-motor experiences of daily living and has 2 components (Range 0-52). Part IA contains 6 questions and are assessed by the examiner (Range 0-24). Part IB contains 7 questions on non-motor experiences of daily living which was completed by the participant (Range 0-28). Part II assessed motor experiences of daily living (Range 0-52). It contained 13 questions completed by the participant. Part III assessed the motor signs of Parkinson's Disease (PD) and was administered by the rater (Range 0-132). Part III contained 33 scores based on 18 items. There are 4 subscores in Part III: Bradykinesia, Rigidity, Resting tremors and Axial symptoms. For each question a numeric score is assigned between 0-4, where 0 = Normal, 1 = Slight, 2 = Mild, 3 = Moderate, 4 = Severe. MDS-UPDRS Total Score equals the sum of Parts I,II, and III (Range:0-236). A higher score indicated more severe symptoms of Parkinson's disease.
2. Change From Baseline in Dopamine Transporter Imaging With Single Photon Emission Computed Tomography (DaT-SPECT) Striatal Binding Ratio (SBR) in the Putamen Ipsilateral to the Clinically Most Affected Side [ Time Frame: From baseline to Week 52 ]
   DaT-SPECT (dopamine transporter imaging with single photon emission computed tomography) is a dopamine transporter SPECT imaging that uses a radioactive agent called 123^I-ioflupane to quantify the density of the dopamine transporters in the striatum. Changes from baseline to week 52 in DaT-SPECT striatal binding ratios (SBRs; reference region: occipital cortex) in the putamen ipsilateral to the clinically most affected side were analyzed.
3. Change From Baseline in Montreal Cognition Assessment (MoCA) Total Score [ Time Frame: From baseline to Week 52 ]
   The Montreal Cognitive Assessment (MoCA) is a rapid screening that was developed to be more sensitive to participants presenting with mild cognitive complaints. It briefly assesses short term and working memory, visuospatial abilities, executive function, attention, concentration, language and orientation. Scores on the MoCA test range from 0-30. Higher scores are associated with better cognitive function.
4. Change From Baseline in Clinical Global Impression of Improvement (CGI-I) Score [ Time Frame: From baseline to Week 52 ]
   The CGI-I was intended as a measure of change in health status. CGI-I scores ranged from 1 (very much improved) through to 7 (very much worse). For the CGI-I, participants were divided into one of two groups, Responders or Progressors. Responders were scored on a scale of 1-4 which was rated as "no change", "minimally improved", "much improved" or "very much improved." Progressors were scored on a scale of 5-7 which was rated as "minimally worse", "much worse" or "very much worse." The percentage of participants rated by CGI-I Scale grouping at week 52 was analyzed using a logistic regression model.
5. Change From Baseline in Patient Global Impression of Change (PGIC) Score [ Time Frame: From baseline to Week 52 ]
   The PGIC was intended as a measure of change in health state from the participants perspective. PGIC scores ranged from 1 (very much improved) through to 7 (very much worse). For the PGIC, participants were divided into one of two groups, Responders or Progressors. Responders were scored on a scale of 1-4 which was rated as "no change", "minimally improved", "much improved" or "very much improved." Progressors were scored on a scale of 5-7 which was rated as "minimally worse", "much worse" or "very much worse." The percentage of participants rated by PGIC Scale grouping at week 52 was analyzed using a logistic regression model.
6. Change From Baseline in Schwab and England Activity of Daily Living (SE-ADL) Score [ Time Frame: From baseline to Week 52 ]
   The SE-ADL is a single item scale assessing Activities of Daily Living on a scale ranging from 0% (bedridden) to 100% (completely independent), using 10% intervals.
7. Time to Worsening in Motor or Non-Motor Symptoms [ Time Frame: From baseline to Week 52 ]
   This outcome measure is defined as the time to between first dose of study medication and the date when the particiapnt increases in MDS-UPDRS Part I (Range 0-52) of 3 or more points, or in MDS-UPDRS Part II (Range 0-52) of 3 or more points, whichever comes first. A higher score indicated more severe motor signs of Parkinson's disease.
8. Time to Start of Dopaminergic Parkinson's Disease Treatment [ Time Frame: From baseline to Week 52 ]
   This endpoint is defined as the time between first dose of study medication and the date when the participant starts dopaminergic treatment.
9. Percentage of Participants With Adverse Events (AEs) and Serious AEs (SAEs) [ Time Frame: From baseline to Week 52 ]
   An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was any AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
10. Percentage of Participants With Anti-Drug Antibodies (ADAs) Against RO7046015 [ Time Frame: Baseline, Pre-dose (0 hours) on Weeks 4, 20, 36, 52, 56, 68, 80, and 104; at early termination (up to Week 104), and follow-up (12 weeks after last dose up to Week 116) ]
    Samples of the participant's blood was taken to evaluate anti-drug antibodies (ADA). The number of ADA positive participants, Treatment-induced and Treatment-enhanced was reported. Treatment-induced = participants with ADA negative or missing data at baseline but develop an ADA response following exposure to the study drug. Treatment-enhanced = participants with ADA positive at baseline and the titre of one or more post-baseline samples is at least >=4 fold increase greater than the baseline titre sample.
11. Systemic Clearance (CL) of RO7046015 [ Time Frame: Predose (0 hours) and end of infusion (infusion length=2 hours or less) on Baseline, Weeks 4, 20, 36, 52, 56, 68, 80, and 104; at Day 7, Day 14, early termination (up to Week 104), and follow-up (12 weeks after last dose up to Week 116) ]
    Clearance is a measure of the rate at which a drug is removed from the body.
12. Apparent Volume of Distribution (Vz/F) of RO7046015 [ Time Frame: Predose (0 hours) and end of infusion (infusion length=2 hours or less) on Baseline, Weeks 4, 20, 36, 52, 56, 68, 80, and 104; at Day 7, Day 14, early termination (up to Week 104), and follow-up (12 weeks after last dose up to Week 116) ]
    Volume of distribution is defined as the theoretical volume which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug.
13. Area Under the Serum Concentration-Time Curve (AUC) of RO7046015 Over the Dosing Interval [ Time Frame: Baseline over the duration of the study ]
    AUC is defined as the measure of RO7046015 plasma concentration over time.
14. Maximum Observed Serum Concentration (Cmax) of RO7046015 at Steady-state [ Time Frame: Baseline over the duration of the study ]
    Cmax is the maximum observed plasma concentration of RO7046015.
15. Minimum Observed Serum Concentration (Ctrough) of RO7046015 at Steady-state [ Time Frame: Baseline over the duration of the study ]
    Cmin is the minimum observed plasma concentration of RO7046015.
