A Clinical Study to Investigate the Effect of Oral Neflamapimod on Motor Recovery After Acute Ischaemic Stroke

The purpose of this interventional study is to determine whether neflamapimod can improve residual physical disability and/or cognitive dysfunction after Moderate to Severe Acute Ischaemic Stroke.

Inclusion Criteria: * Male or female participants must be aged 45 years or over at the time of signing the informed consent. * Confirmed acute ischaemic stroke in the anterior circulation (middle or anterior cerebral artery) with onset of symptoms between 2 and 7 days prior to screening and evaluation. * National Institutes of Health Stroke Scale (NIHSS) score between 5 and 20 (inclusive) and exhibiting unilateral motor deficit (i.e. motor NIHSS ≥ 2 on affected side of the body). * Fugl-Meyer Assessment of Motor Recovery after Ischaemic Stroke (FMMS) total motor components score of 80 or below. * No history of learning difficulties that may interfere with their ability to complete the cognitive tests. Exclusion Criteria: * Evidence of progressive or unstable stroke or intra-cerebral haemorrhage in the opinion of the investigator * Participants needing carotid surgery within 3 months * Ongoing major and active psychiatric disorder and/or other concurrent medical condition that, in the opinion of the Investigator, might compromise safety and/or compliance with study requirements. * History of alcohol or drug abuse within the previous 2 years. * Poorly controlled clinically significant medical illness, such as hypertension (blood pressure \>180 mmHg systolic or 100 mmHg diastolic); myocardial infarction within 6 months; uncompensated congestive heart failure or other significant cardiovascular, pulmonary, renal, liver, infectious disease, immune disorder, or metabolic/endocrine disorders or other disease that would interfere with assessment of drug safety in the opinion of the Investigator. * Abnormal laboratory tests that, in the Investigator's assessment, mean that a participant is not appropriate for participation in this study, including, but not limited to: 1. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \>2.0 × the upper limit of normal (ULN), 2. Total bilirubin \>1.5 × ULN, and/or 3. International Normalised Ratio (INR) \>1.5 NOTE: Participants with Gilbert's syndrome can be included with total bilirubin \>1.5 x ULN as long as direct bilirubin is ≤ 1.5 x ULN)
