MLC1501 Study Assessing Efficacy in Post STrOke Subjects With mOtor Deficits

Phase 2

Recruiting

• Conditions: Strokes Thrombotic; Stroke, Ischemic; Stroke, Embolic; Stroke, Cryptogenic; Stroke; Stroke, Cardiovascular; Stroke Sequelae
• Interventions: Other: Placebo; Drug: MLC1501

• Registration Number: NCT05289947
• Lead Sponsor: Moleac Pte Ltd.

Brief Summary

This is a multi-center, randomized, double-blind, placebo-controlled trial of MLC1501 in patients with stroke. Eligible participants will be randomized in a 1:1:1 ratio to orally receive MLC1501 high-dose twice a day, MLC1501 low-dose twice a day, or matching placebo for 24 weeks.

Detailed Description

A total of 300 patients will be included with approximately 100 patients randomized to each treatment arm. Randomization will be performed centrally and stratified according to the following factors at the time of randomization: country, National Institute of Health Stroke Scale (NIHSS) (8 to 12, 13 to 18) and received either intravenous or endovascular thrombolysis/thrombectomy (no, yes).

Efficacy clinical assessments will include Fugl-Meyer motor Assessment (FMA), modified Rankin Scale (mRS), Patient Reported outcome Measurement Information System - Global Health (PROMIS-10) and NIHSS.

Each patient will undergo standard safety assessments including physical exam and laboratory parameters, and be observed for adverse events for the duration of the study. Electrocardiogram (ECG), hematology, clinical chemistry, coagulation, and urinalysis will be performed at specified intervals.

• Contraindication to any of the study procedures.
• Patients who became medically unstable within 24 hours after intravenous or endovascular thrombolysis or thrombectomy.
• Intake of any herbal or traditional medicine within the past 30 days.
• Participation in another investigational drug or device trial within the past 30 days.
• Intake of warfarin in the past one week or expected to be on warfarin while in the study.

• Evidence of other significant non-ischemic brain lesion which could affect long-term function or disability.
• Evidence of advanced medical condition that would affect study assessment and follow-up, such as cancer, renal failure, liver cirrhosis, severe dementia, or psychosis.
• Any other medical or psychiatric or cognitive condition which, in the study investigator's opinion, may jeopardize the patient by his/her participation in this study, may hamper his/her ability to complete procedures required in the study, affect study assessment and follow-up, or affect the validity of the study results.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	500-mg placebo capsule, 4 capsules twice a day for 24 weeks
MLC1501 Low-dose	MLC1501	MLC1501 low-dose 500-mg capsule, 4 capsules twice a day for 24 weeks
MLC1501 High-dose	MLC1501	MLC1501 high-dose 500-mg capsule, 4 capsules twice a day for 24 weeks

Primary Outcome Measures

Name	Time	Method
Fugl-Meyer motor Assessment (FMA)	24 weeks	The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia

Secondary Outcome Measures

Name	Time	Method
Fugl-Meyer motor Assessment (FMA)	12 and 24 weeks
modified Rankin Scale (mRS)	4, 12 and 24 weeks	The Modified Rankin Score (mRS) is a 6 point disability scale with possible scores ranging from 0 (no symptoms at all) to 5 (severe disability). A separate category of 6 is usually added for patients who expire.
Patient Reported Outcome Measurement Information System - Global Health (PROMIS-10)	4, 12 and 24 weeks	The PROMIS Global-10 is a 10-item patient-reported questionnaire in which the response options are presented as 5-point (as well as a single 11-point) rating scales. The results of the questions are used to calculate two summary scores: a Global Physical Health Score and a Global Mental Health score. These scores are then standardized to the general population, using the "T-Score". The average "T-Score" for the United States population is 50 points, with a standard deviation of 10 points. Higher scores indicate a healthier patient.
Adverse events	up to 24 weeks	Listing and calculating the number and percentage of subjects experiencing non-serious and serious adverse events for each dose cohort
National Institute of Health Stroke Scale (NIHSS)	12 and 24 weeks	The maximum possible score is 42 (severe), with the minimum score being a 0 (no symptoms)
