A Proof of Concept Study to Evaluate the Safety of Afamelanotide in Patients With Acute Arterial Ischaemic Stroke (AIS)

Clinuvel

Status and phase: Completed; Phase 2

Conditions: Arterial Ischemic Stroke

Treatments: Drug: Afamelanotide

Study type: Interventional

Funder types: Industry

Identifiers

NCT04962503

CUV801

Details and patient eligibility

About

The primary study objective is to assess the safety of afamelanotide while the secondary objective is to assess whether the therapy affects the size of the penumbra, by increasing blood flow, restoring oxygen supply to the brain, and reducing the amount of cerebral oedema (fluid) which is seen as a result of the stroke. Positive findings would indicate that the drug is able to support brain tissue-at-risk and provide overall neuroprotection and benefit to stroke patients.

Enrollment: 6 patients

Sex: All

Ages: 18 to 85 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Male or female subjects with a diagnosis of first AIS due to distal [M2 segment and beyond] occlusion or perforator occlusion
• Perfusion abnormalities observed on Computed Tomography Perfusion (CTP)
• Mild to moderate stroke severity
• Pre-stroke mRS <4
• Written informed consent obtained from patient and/or medical treatment decision maker prior to study-start (upon admission).

Exclusion criteria

• Administration of intravenous thrombolytic therapy in distal occlusion as etiology of AIS
• Intervention by endovascular thrombectomy (EVT)
• Known allergy or anaphylaxis to adrenocorticotropic hormone (ACTH) or melanocortins or any of the excipients listed in the Investigator's Brochure
• Any evidence of hepatic (defined as three times standard range) or renal impairment (defined as estimated glomerular filtration rate (eGFR) <50 mL/min/1.73 m²)
• Any other medical condition which may interfere with the study protocol
• Female who is pregnant (confirmed by positive serum beta human chorionic gonadotropin (β-HCG) pregnancy test prior to baseline) or lactating
• Females of child-bearing potential (pre-menopausal, not surgically sterile) not using adequate contraceptive measures (i.e. oral contraceptives, diaphragm plus spermicide, intrauterine device) or a lifestyle excluding pregnancy
• Unable to undergo MRI brain evaluation
• Not suitable for trial participation according to judgment of the Principal Investigator (PI)
• Patients starting afamelanotide 24 hours or more from ictus.
