Full description
The purpose of this research study is to test two medicines for migraine prevention in children and adolescents. The investigators want to see if amitriptyline and/or topiramate are better than placebo (sugar pill) in reducing headache frequency in children and adolescents ages 8 to 17 with migraines. At this time, there are no FDA approved medicines approved in the US for the prevention treatment of migraine headaches in children and adolescents.

Inclusion criteria
Migraine with or without aura (International Classification of Headache Disorders, 2nd Edition (ICHD-II) or chronic migraine (ICHD-II revised)
Migraine frequency based upon prospective headache diary of 28 days must be ≥ 4. Migraine frequency defined as any migraine during one day in the 28 day baseline period (1)
PedMIDAS Disability Score > 10, indicating at least mild disruption in daily activities and < 140, indicating extreme disability that may require more comprehensive, multi-component therapy
Females or males 8-17 years, inclusive
Exclusion criteria

Currently taking other prophylactic anti-migraine medication within a period equivalent to 2 weeks of that medication before entering the screening phase, or the use of Botulinum toxin (Botox®) within 3 months of entering the screening phase
Subjects who have previously failed an adequate trial of AMI or TPM for prophylaxis of at least 3 months duration at doses recommended for migraine relief because of lack of efficacy or adverse events(2)
Current use of disallowed medications/products: opioids, antipsychotics, antimanics, barbiturates, benzodiazepines, muscle relaxants, sedatives, tramadol, nutraceuticals, SSRIs, or SSNRIs
Known history of allergic reaction or anaphylaxis to AMI or TPM
Abnormal findings on ECG at baseline, particularly lengthening of the QT interval greater than or equal to 450 msec
Subject is pregnant or has a positive pregnancy test
Subject is sexually active and not using a medically acceptable form of contraception
Diagnosis of epilepsy or other neurological diseases
History of kidney stones
Inability to swallow pills after using behavioral techniques if indicated between screening visit and baseline visit (3)
Present psychiatric disease as defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM IV) (e.g. psychosis, bipolar disorder, major depression, generalized anxiety disorder), alcohol or drug dependence, or documented developmental delays or impairments (e.g., autism, cerebral palsy, or mental retardation) that, in the opinion of the site investigator, would interfere with adherence to study requirements or safe participation in the trial
Any and all other diagnoses or conditions which in the opinion of the site investigator, that would prevent the patient from being a suitable candidate for the study or interfere with the medical care needs of the study subject
(2)"Previously failed an adequate trial of AMI or TPM" is defined as: dosage of 1mg/kg/day of AMI or 2 mg/kg/day of TPM; trial of at least 3 months duration; efficacy of having at least a 50% decrease in migraine frequency in response to drug therapy; or unable to tolerate taking the medication due to treatment-related side effects.
(3)Subjects who cannot swallow pills at the time of the screening visit will be given a training session using behavioral techniques. Upon return for baseline visit, if the subject continues to be unable to swallow pills, the subject will be excluded from the study.
