Inclusion criteria

Subject is >10 years of age and <17 years of age at the informed consent and the Randomization Visit.

Subject has a history of at least two, but no more than eight, attacks per month for the two months prior to entry into the study.
All migraine attacks associated with 3 or more pain on a 5-grade scale should last a minimum of three hours for the two months prior to entry into the study.
Subject has shown nonresponse to at least one NSAIDs or acetaminophen for the two months prior to entry into the study.
Subject is able to distinguish migraine from other headaches (e.g., tension-type headache).
Subject is able to read, comprehend, and complete subject diaries.
Males or female subjects. Female subjects are eligible for participation in the study if they are one of the following
Females of non-childbearing potential (i.e., physiologically incapable of becoming pregnant or have undergone female sterilization)
Females of childbearing potential, and who have a negative pregnancy test at the Screening Visit, and agree to use one of the following GlaxoSmithKline (GSK)-specified highly effective methods for avoiding pregnancy:
Abstinence
Oral Contraceptive, either combined or progestogen alone
Male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study, and this male is the sole partner for that subject)
Double barrier method: condom or occlusive cap (diaphragm or cervical/vault caps) plus spermicidal agent (foam/gel/film/cream/suppository)
Subject's parent or legal guardian is willing and able to provide informed consent prior to subject entry into the study.
Subject is willing and able to provide informed assent prior to entry into the study.
Subjects considered for enrolment must have a QTc (either QTc B (Bazett's correction) or QTc F (Fridericia's correction)) <450msec at the Screening Visit, with the exception of subjects with bundle branch block (for whom either QTc B or QTc F must be <480msec).

Note: For the purposes of these criteria, QTc B is defined as (QT interval msec) / (square root of RR interval seconds); and QTc F is defined as (QT interval msec) / (cube root of RR interval seconds).)

Liver function test at the Screening Visit: AST and ALT <2xULN; alkaline phosphatase and total bilirubin <1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%)

Exclusion criteria
