Eligibility Criteria

Exclusion Criteria

Patients will be excluded from this study if they meet any of the following criteria:

Target Disease Exclusion:

• Migraine with brainstem aura or hemiplegic migraine
• Headache (migraine or non-migraine) ≥ 15 days per month in any month during the 3 months prior to the screening visit
• Patients with migraine with medication overuse headache

Medical history and co-morbidities:

• History of HIV infection
• Migraine or head or neck regional interventions/devices (e.g., nerve blocks or transcranial magnetic stimulation) within 2 months prior to enrolment
• Uncontrolled, unstable or recently diagnosed cardiovascular disease (ischaemic heart disease, coronary vasospasm and cerebral ischaemia). Myocardial infarction, acute coronary syndrome, undergoing percutaneous coronary intervention, cardiac surgery, experiencing a stroke or transient ischaemic attack within 6 months (24 weeks) prior to the screening visit.
• Uncontrolled hypertension or uncontrolled diabetes mellitus. Subjects with a history of hypertension, hypercholesterolaemia and/or diabetes mellitus but whose current status is stable and controlled and who have been receiving a stable dose of medication for at least 3 months (12 weeks) prior to the Screening Visit may be enrolled in the study.
• History of gastric or small bowel surgery (including gastric bypass, gastric banding, sleeve gastrectomy, intragastric ballooning, etc.) or a condition that causes malabsorption (e.g., chronic pancreatitis, ulcerative colitis, etc.)
• History of Gilbert's syndrome or current diagnosis of Gilbert's syndrome or any other active liver or biliary tract disease.
• Diagnosis of haematological or solid malignancy within 5 years prior to screening. For subjects with a history of localised basal cell carcinoma or squamous cell skin cancer, they will be eligible to participate in this study if they are confirmed to be cancer free prior to the screening visit.
• Any previous or current unstable medical condition (e.g., congenital heart disease or history of cardiac arrhythmia, known or suspected infection, cancer) that, in the opinion of the investigator, would place the subject at increased risk of a significant adverse event during the course of the trial or interfere with the safety/efficacy assessment.
• Active chronic pain syndromes (e.g. fibromyalgia, chronic pelvic pain, complex localised pain syndrome).
• Have other pain syndromes (including trigeminal neuralgia), psychiatric disorders, dementia, or major neurological disorders (other than migraine) that, in the opinion of the investigator, may interfere with study evaluation
• Current or previous diagnosis of schizophrenia, bipolar disorder or borderline personality disorder
• Has had a depressive episode within the past 12 months or requires more than 1 standard treatment medication daily to treat their depressive disorder or anxiety disorder. For medications used to treat a depressive disorder or anxiety disorder, the medication must have been maintained at a stable dose for at least 3 months prior to the Screening Visit.
• History, treatment history, or evidence of alcohol or drug abuse in the 12 months (48 weeks) prior to the Screening Visit, or a history of substance abuse consistent with any of the DSM-5 Significant Substances in the 12 months (48 weeks) prior to the Screening Visit through the end of the double-blind treatment period.
• Subjects should be excluded if they have a positive screening result for addictive drugs that, in the opinion of the Investigator, is medically significant and would compromise the safety of the subject or the interpretation of the study results. In addition:
• Cocaine, amphetamines, phencyclidine (PCP), and tetrahydrocannabinol (THC) at detectable levels on the Drug Screen need to be excluded.
• Subjects who have a positive drug screen for amphetamines and are using a prescription amphetamine drug for one of the approved indications (e.g., Attention Deficit Hyperactivity Disorder [ADHD]) may be enrolled in the study at the discretion of the Investigator. The Investigator's decision must be documented in detail in the subject's source medical record. Stimulant dosage must remain stable from the first 3 months (12 weeks) of the observation period to the end of the double-blind treatment period.
• BMI ≥ 33.0 kg/m2

ECG and laboratory findings:

• Corrected QT interval > 470 ms at screening (QTc corrected using the Fridericia method)
• left bundle branch block
• Right bundle branch block with QRS duration ≥150 ms
• Intracardiac conduction defect with QRS duration ≥150 ms
• Serum bilirubin (total bilirubin, direct bilirubin, or indirect bilirubin) > 2 x ULN.
• AST or ALT > 3 × ULN.
• Neutrophil count ≤ 1000/μL (or equivalent)

Allergies and other factors:

• History of celery allergy
• Tendency to bleed

• Females who are pregnant or breastfeeding.
• Females with a positive pregnancy test result at screening or prior to study drug administration.

Men of childbearing potential who have an active sex life with a woman of childbearing potential but are unwilling or unable to use one or more acceptable methods of contraception or abstinence to avoid pregnancy with their partner throughout the study period and for 90 days after the last dose of study drug.

• Minimum Eligible Age: 18 Years
