E.3 | Principal inclusion criteria |
1. Females childbearing and non-childbearing potential , between 18 and 55 years of age. 2. Subjects, otherwise healthy, suffering from migraine with or without aura, according to 2004 IHS criteria 1.1 and 1.2.1 Appendix 2 . Healthy subjects are defined as individuals who are free from clinically significant illness or disease as determined by their medical history including family , physical examination, laboratory studies, and other tests . 3. Subject has had migraine for at least one year, and the age of onset was prior to 50 years. 4. Subject has consistent migraine headache over time i.e., incidence and severity . 5. Subject had at least 3 migraine headache attacks but less than 15 headache days migraine or non-migraine per month in each of the three months prior to the Screening Visit and maintains this requirement during the baseline period. 6. Subject is able to distinguish migraine headache attacks as discreet attacks from other headaches i.e. tension-type headaches . 7. No clinically significant abnormality identified on the medical or laboratory evaluation, including 12 lead ECG. A subject with a clinical abnormality or laboratory parameters outside the reference range may be included only if the Investigator considers that the finding will not introduce additional risk factors and will not interfere with the study procedures. 8. Subject has the ability to read, comprehend and legibly and reliably record information in paper and electronic format as required by the protocol. 9. Subject gives written informed consent prior to entry into the study. 10. A female is eligible to enter and participate in this study if she is of a non-childbearing potential i.e., physiologically incapable of becoming pregnant, including any female who is post-menopausal 1 year since last menstrual cycle , had a documented tubal ligation or is surgically sterilized ; or, b child-bearing potential, has a negative pregnancy test urine at screen, and agrees to one of the following 1. Complete abstinence from intercourse from 2 weeks prior to administration of the investigational product, throughout the Treatment Period and for a minimum of one week after completion or premature discontinuation from investigational product; or 2. Consistent and correct use of an acceptable method of birth control listed below a. Female sterilization; or b. Male partner s who is are sterile prior to the female subject s entry into the study and is are the sole sexual partner s for that female subject; or c. Implants of levonorgestral within the lifetime of the implant; or d. Injectable progesterone; or e. Oral contraceptive combined or progestogen only started at least 2 months prior to the Screening Visit; or f. Documented placement of any Intrauterine Device IUD with published data showing that the highest expected failure rate is less than 1 per year; or g. Double barrier contraception e.g., a combination of physical and chemical methods, preferably a spermicide with either a condom or a diaphragm ; or h. Any other method of contraception with data documented in the product labelling as approved by regulatory agencies, or in the absence of approved labelling, in peer reviewed studies, showing that the highest expected failure rate for that method is less than 1 per year. |

E.4 | Principal exclusion criteria |
1. As a result of the medical interview, physical examination or screening investigations, that the Investigator or appropriately qualified designee considers the subject unfit for the study. 2. Subject has headache for 15 days per month or greater in any of the three months 90 days preceding the Screening Visit. 3. Subject has history of alcohol, substance or drug abuse within the last year. 4. Subject has taken a migraine prophylactic medication within 1 month of the Screening Visit. 5. Subject uses an opiate as first line acute treatment for migraine attacks. 6. Subject has history of ergotamine, triptan, opioid, or combination medication intake on 10 days per month on a regular basis for 3 months. 7. Subject has history of simple analgesic intake on 15 days per month for 3months. 8. Subject has failed two or more adequate treatments of migraine prophylaxis -where failure is defined as a lack of efficacy with a treatment duration of at least 8 weeks or withdrawal of treatment due to treatment intolerance. 9. Subject has uncontrolled hypertension at the Screening Visit, defined as persistent after 3 readings systolic blood pressure 140mmHg or diastolic blood pressure 90mmHg; measured after 10 minutes of rest. 10. Subject is taking cyclosporine and/or aminoglycosides. 11. Evidence of renal impairment - calculated creatinine clearance 60ml/min Cockroft-Gault formula, Appendix 4 or clinically relevant finding more than 1 protein or blood on urinalysis including microscopy . 12. Subject has a history of drug or other allergy which, in the opinion of the Investigator, makes the subject unsuitable for participation in the study. 13. Subject is concurrently participating in another clinical study or investigational drug trial or has participated within the previous 3 months or is planning to participate in another drug or device study at any time during this study screening through follow-up or has had previous exposure to GW274150 in Part 1 of the study. 14. Subject is felt to be at risk of non-compliance for taking study medication or for completing the electronic diary e-diary , in the Investigator s opinion. 15. Pregnant or nursing women. 16. History of, or risk factors for, HIV, Hepatitis B and Hepatitis C. 17. Past or present disease, which as judged by the investigator, may affect the outcome of this study. These diseases include, but are not limited to history of liver or renal disease in the 6 months prior to screening. 18. Clinically significant abnormalities in safety laboratory analysis at the Screening Visit. Particularly any liver function test including ALT, AST and ALP or pancreatic function test pancreatic amylase or lipase 1.5 x upper limit normal ULN at the Screening Visit. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the occurrence of a migraine headache day on each day during the 4-week baseline period and the 12-week treatment period, where a migraine headache day is defined as a calendar day with any occurrence of migraine headache pain of at least 30 minutes in duration. The primary safety endpoints include the incidence and severity of clinical adverse events, as well as changes from baseline to Weeks 2, 4, 6, 8 and 12 Visits for clinical laboratory parameters and vital signs, and ECG abnormalities at the Weeks 4, 8 and 12 Visits. |
