Brief Summary:

The main aim is to see how TAK-341 works after 52 weeks in participants with multiple system atrophy as measured by the Unified Multiple System Atrophy Rating Scale Part I (UMSARS).

The study will enroll approximately 138 patients. Participants will receive a total of 13 intravenous infusions every 4 weeks approximately, these may be either of TAK-341 or placebo, after each infusion some blood samplings will be taken and other assessments completed.

This trial will be conducted in North America, Europe and Asia.


Condition or disease Intervention/treatment Phase
Multiple System Atrophy Drug: TAK-341 Drug: Placebo Phase 2

Detailed Description:

The drug being tested in this study is called TAK-341. The study will evaluate the efficacy, safety, tolerability, pharmacokinetics (PK), and pharmacodynamics of intravenous (IV) TAK-341 in participants with multiple system atrophy (MSA).

The study will enroll approximately 138 participants. The study comprises a screening period of up to 42 days (6 weeks), a 52-week double-blind treatment period, and a follow-up safety visit. Participants will be randomly assigned (by chance, like flipping a coin) to one of the treatment schedules-which will remain undisclosed to the participant, care provider and investigator during the study:

  • Early PK Cohort: TAK-341
  • Early PK Cohort: Placebo
  • Main Cohort: TAK-341
  • Main Cohort: Placebo

The change from baseline in UMSARS will be measured at Week 52 post-dose.

This multi-center trial will be conducted worldwide. The duration of treatment in this study will be 52 weeks. Participants will make a follow-up visit to the site after approximately 90 days after the last dose of study treatment.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change from Baseline in a Modified Unified Multiple System Atrophy Rating Scale (UMSARS) Part I at Week 52 [ Time Frame: Up to 52 weeks ]
    UMSARS Part I (historical review) is a 11-item scale that was adapted from the Unified Parkinson's Disease Rating Scale (UPDRS) and is used to assess activities related to motor disability and related to autonomic dysfunction. Each item is scored from 0 (normal) to 3 (severe). The total score is a sum of scores from all domains and can range from 0 to 33. Higher scores mean poorer health.


Secondary Outcome Measures :
  1. Change From Baseline in 11-item UMSARS at Week 52 [ Time Frame: Up to 52 weeks ]
    The 11- item UMSARS includes 11 items from Part I and II to assesses both motor and autonomic disability. UMSARS Part I (historical review) is used to assess activities related to motor disability and autonomic dysfunction. UMSARS Part II (motor examination) is used to measure the functional impairment and specific parkinsonian or cerebellar features. Each item is scored from 0 (normal) to 4 (severe). The total score is a sum of scores from all domains and can range from 0 to 44. Higher scores mean poorer health.

  2. Change From Baseline in UMSARS Total Score (UMSARS Part I + Part II) at Week 52 [ Time Frame: Up to 52 weeks ]
    UMSARS total scale consists of all items from UMSARS Parts I and II. UMSARS Part I (historical review): 12-item scale used to assess activities related to motor disability and autonomic dysfunction. Each item is scored from 0 (normal) to 4 (severe). UMSARS Part II (motor examination): 14-item scale used to measure the functional impairment (eg, speech, rapid alternating movements of the hands, finger taps, leg agility) of selected complex movements, and specific parkinsonian (tremor at rest) or cerebellar (ocular motor dysfunction, heel-shin test) features. Each item is scored from 0 (normal) to 4 (severe).

  3. Change From Baseline in UMSARS Part I at Week 52 [ Time Frame: Up to 52 weeks ]
    UMSARS Part I (historical review) is a modified 11-item scale that was adapted from the UPDRS and is used to assess activities related to motor disability (first 8 items) and 4 novel items related to autonomic dysfunction. Each item is scored from 0 (normal) to 4 (severe). The total score is a sum of scores from all items and can range from 0 to 44. Higher scores mean poorer health.

  4. Change From Baseline in UMSARS Part II at Week 52 [ Time Frame: Up to 52 weeks ]
    UMSARS Part II (motor examination) is a 14-item scale. Most of the items (e.g., speech, rapid alternating movements of the hands, finger taps, leg agility) measure the functional impairment of selected complex movements, and only a few items directly refer to specific parkinsonian (tremor at rest) or cerebellar (ocular motor dysfunction, heel-shin test) features. The motor examination section of UMSARS was based on modified UPDRS-III items in addition to novel items such as heel-knee-shin ataxia. Each item is scored from 0 (normal) to 4 (severe). The total score is a sum of scores from all items and can range from 0 to 56. Higher scores mean poorer health.

  5. Clinical Global Impression-Severity (CGI-S) Score [ Time Frame: Up to 52 weeks ]
    The CGI-S is used to assess the clinician's impression of the participant's clinical condition. The clinician should use his or her total clinical experience with this participant population and rate the current severity of the participant's illness on a 7-point scale ranging from 1 for normal, not at all ill to 7 for among the most extremely ill participants. Higher scores mean better health.

  6. Change From Baseline in Scales for Outcomes in Parkinson's Disease - Autonomic Dysfunction (SCOPA-AUT) Total Score [ Time Frame: Up to 52 weeks ]
    The SCOPA-AUT is a patient-reported outcome that assesses autonomic function. Autonomic function is a critical symptom domain for MSA. The scale is self-completed by participants and consists of 25 items assessing the following domains: gastrointestinal (7 items), urinary (6 items), cardiovascular (3 items), thermoregulatory (4 items), pupillomotor (1 item), and sexual (2 items for men and 2 items for women). The score for each item ranges from 0 (never experiencing the symptom) to 3 (often experiencing the symptom). The total composite score including all domains will be reported. The score range is 0 (no symptoms) to 69 (highest burden of symptoms).

  7. Overall Survival (OS) [ Time Frame: Up to 52 weeks ]
    OS is defined as time from the first day of study drug administration to death due to any cause.

  8. Change from Baseline on Levels of Cerebrospinal Fluid (CSF) Free Alpha-synuclein (αSYN) [ Time Frame: Up to 52 weeks ]
  9. Cmax: Maximum Observed Serum Concentration for TAK-341 [ Time Frame: Pre-dose on Days 1, 29, 57, 85, 169, 253, 337; at multiple timepoints (up to 24 hours) post-dose on Days 1, 57, 85, 169, 337; anytime once on Days 365, 427 or at early termination (Day 57 applicable to only early PK cohorts) ]
  10. Tmax: Time of First Occurrence of Cmax in Serum for TAK-341 [ Time Frame: Pre-dose on Days 1, 29, 57, 85, 169, 253, 337; at multiple timepoints (up to 24 hours) post-dose on Days 1, 57, 85, 169, 337; anytime once on Days 365, 427 or at early termination (Day 57 applicable to only early PK cohorts) ]
  11. AUCτ: Area Under the Concentration-time Curve During a Dosing Interval in Serum for TAK-341 [ Time Frame: Pre-dose on Days 1, 29, 57, 85, 169, 253, 337; at multiple timepoints (up to 24 hours) post-dose on Days 1, 57, 85, 169, 337; anytime once on Days 365, 427 or at early termination (Day 57 applicable to only early PK cohorts) ]
  12. CSF Concentration of TAK-341 [ Time Frame: Pre-dose on Days 1, 85 (applicable to only early PK cohorts), and 365 ]
    Lumbar puncture for CSF sampling will be performed.

  13. Number of Participants With at Least one Adverse Event (AE) [ Time Frame: Up to 52 weeks ]
    An adverse event (AE) is defined as any untoward medical occurrence in a participants administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. Data will be reported for number of participants to be analyzed for safety parameters that will include clinically significant abnormal values for clinical laboratory evaluations, vital signs, ECG parameters, physical examination, neurological examination and Columbia-Suicide Severity Rating Scale (C-SSRS).

  14. Number of Participants With Antidrug Antibody [ Time Frame: Up to 52 weeks ]
