Study of NBMI Treatment in Patients With Atypical Parkinsons (PSP or MSA) (EMERA006)

A Pilot Exploratory, Randomised, Placebo-controlled, Double Blinded, Cross-over , Phase 2a Study to Explore Efficacy and Safety of NBMI Treatment in Patients With Progressive Supranuclear Palsy (PSP) or Multiple System Atrophy (MSA)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes in Progressive Supranuclear Palsy rating Scale (PSPRS) individual scales scores from baseline in PSP patients compared to placebo treatment	For PSP specific scales (to study on PSP patients):- Progressive Supranuclear Palsy rating Scale is used as a quantitative measurement of disability in PSP patients. The available total score ranges from 0 (normal) to 100. Six items are rated on a 3-point scale (0-2) and 22 are rated on a 5-point scale (0-4). The History/Daily Activities area includes seven items with a total maximum of 24 points, the mentation area four items with 16 points, the bulbar area two items with 8 points, the ocular motor area four items with 16 points, the limb motor area six items with 16 points and the gait area five items with 20 points. Scores from each subscale is summed and combined to compute a total score. Higher values for each scale range provided represent worse outcome.	through study completion, an average of 85 days
Changes in FAB individual scales scores from baseline in PSP patients compared to placebo treatment	For PSP specific scales (to study on PSP patients):- Frontal Assessment Battery (FAB) is a brief tool that can be used at the bedside or in a clinic setting to assist in discriminating between dementias with a frontal dysexecutive phenotype and Dementia of Alzheimer's Type (DAT). The FAB has validity in distinguishing Fronto-temporal type dementia from DAT in mildly demented patients (MMSE > 24). The 6 subtests of the FAB explore the following: conceptualization and abstract reasoning; mental flexibility; motor programming and executive control of action; resistance to interference; inhibitory control; and environmental autonomy. Each subtest is scored from 3 (better score) to 0, for a maximum score of 18. Scores from each subscale is summed and combined to compute a total score. Higher scores indicate better performance.	through study completion, an average of 85 days
Changes in Unified Multiple System Atrophy Rating Scale (UMSARS) individual scale from baseline in MSA patients compared to placebo treatment	Unified Multiple System Atrophy Rating Scale (UMSARS) is a multimodal scale used to provide a surrogate measure of disease progression in multiple system atrophy. Components: Part I, historical, 12 items; Part II, motor examination, 14 items; Part III, autonomic examination (descriptive); and Part IV, global disability scale. Scale is used by physician who rates the average functional situation for the past 2 weeks (unless specified) according to the patient and caregiver interview. Scores are ranging from 0 to 104; higher scores indicate greater impairment. Rating scale includes autonomic symptoms (questions 9-12 - activities of daily living subscale [range 0-16]) and motor symptoms (questions 1-8 - activities of daily living subscale [range 0-32] and the UMSARS motor examination subscale, range 0-56), as well as their effect on activities of daily life (activities of daily living subscale, range 0-48). Scores from each subscale is summed and combined to compute a total score.	through study completion, an average of 85 days
Changes in Non-Motor Symptoms assessment scale (NMSS) individual scale from baseline in MSA patients compared to placebo treatment	Non-Motor Symptoms assessment scale for Parkinson s disease assesses 9 domains: Cardiovascular (2 items); Sleep/fatigue (4 items); Mood/cognition (6 items); Perceptual problems/hallucinations (3 items); Attention/memory (3 items); Gastrointestinal tract (3 items); Urinary function (3 items); Sexual function (2 items); and Miscellaneous (4 items). Score for each item is based on a multiple of severity (from 0 to 3) and frequency scores (from 1 to 4). The scale can therefore capture symptoms that are severe but relatively infrequent and those that may be less severe but persistent. Scores from each subscale is summed and combined to compute a total score. Lower result indicates better health results.	through study completion, an average of 85 days
Changes in QOL individual scores from baseline by MSA questionnaire in MSA patients	MSA-QoL is a patient-rated health-related Quality of life scale for patients with multiple system atrophy (MSA). It is designed to test its psychometric properties. Items are given a standard five response option format (0 - no problem to 4 - extreme problem), where higher scores indicate worse health results. The available total score ranges from 0 to 160 (there are 40 questions altogether).	through study completion, an average of 85 days
Changes in QOL individual scores from baseline by MSA questionnaire in MSA patients using Visual Analog score	MSA-QoL is a patient-rated health-related Quality of life scale for patients with multiple system atrophy (MSA). Visual Analog score is designed to determine overall life satisfaction in patient with MSA. Scale is given response option format (0 - extremely unsatisfied with life 100 - extremely satisfied with life), where higher scores indicate better satisfaction/quality of life.	through study completion, an average of 85 days
Changes in QOL individual scores from baseline by EQ-5D score in PSP patients compared to placebo treatment	EuroQol (EQ-5D) is a standard Health related Quality of questionnaire scale that is completed by patient. It comprises from questions related to 5 different aspects of health such as mobility, self- care, usual activities, pain/ discomfort, anxiety/depression) and a visual health assessment scale completed by patient graphically. Visual scale has following range: 0 (worst possible state) - 100 (best possible state). A scale is completed by patients.	through study completion, an average of 85 days

AEs will be coded according to MeDRA (Medical Dictionary for Regulatory Activities), latest version. They will be tabulated, summarised and divided by treatment group. AEs tabulation will be done in descending order by event frequency per system organ class. Change from baseline will be calculated for laboratory values and vital signs.
