Pharmacokinetics & Safety of Cambia® in Migraine With or Without Aura in 12-17 Year Olds

Inclusion Criteria

• Subject is ≥12 and ≤17 years of age at screening.
• Subject diagnosed with episodic migraine with or without aura for at least 3 months (migraine defined based on the International classification of headache disorders-II 1.2.1 or 1.1).
• Subject has 14 or fewer headache days per month.
• Subject receiving prophylactic treatment for migraine may be included.
• If female, is not of childbearing potential (defined as premenarchal) or if of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test on Study Day 1, if the Screening visit and Day 1 are not on the same day, and must use medically acceptable methods of birth control as listed below and agrees to continue its use throughout the study:1) hormonal methods (e.g., oral, implantable, injectable, or transdermal contraceptives for a minimum of 1 full menstrual cycle before study drug administration), 2) Total abstinence from sexual intercourse since the last menses before study drug administration, 3) intrauterine device, 4) double-barrier method (e.g., condoms, sponge, diaphragm, or vaginal ring with spermicidal jellies or cream).
• Subject's legally authorized representative (e.g., parent, guardian) must voluntarily sign and date an informed consent form (ICF) that is approved by an Institutional Review Board (IRB), and the subject must sign an assent (if appropriate), before the commencement of any study assessment.
• Subject's legally authorized representative (e.g., parent, guardian) and subject (if appropriate), is able to read and understand the study procedures and requirements and adhere to the protocol requirements and procedures.

Exclusion Criteria

• Subject has a known history of allergic reaction, hypersensitivity, or clinically significant intolerance to diclofenac, aspirin, or any nonsteroidal anti inflammatory drugs (NSAIDs); history of NSAID induced bronchospasm (subjects with the triad of asthma, nasal polyps, and chronic rhinitis are at greater risk for bronchospasm and should be considered carefully); or hypersensitivity, allergy, or significant reaction to the non-active ingredients of the study medication.
• Subject is pregnant or lactating or considered at risk of pregnancy.
• Subject has been under an inconsistent dosing regimen of prophylactic treatment for migraine.
• Subject has headache symptoms likely due to, or aggravated by, traumatic injury to the head or neck region, such as whiplash, within the last six months;
• Subject has or is suspected of having a secondary headache.
• Subject has significant abnormal findings during the neurological exam at screening.
• Subject has a history of any GI event (e.g., perforation, obstruction, bleed) before Screening that, in the opinion of the investigator, would make the subject unsuitable for study participation.
• Subject is receiving any medication that, in the opinion of the investigator, may cause a clinically significant condition when used concomitantly with diclofenac (e.g., aspirin, anticoagulants, ACE inhibitors, methotrexate, cyclosporine, furosemide, lithium).
• Subject is and has been receiving a medication that is known to strongly inhibit and/or induce cytochrome P450 2C9 such that it might unpredictably affect the pharmacokinetics of diclofenac (e.g., fluconazole, amiodarone, oxandrolone, sulfipyrazone as inhibitors and rifampin as an inducer).
• Subject has any condition or any laboratory abnormality that would, in the opinion of the investigator, contraindicate study participation.
• Subject has impaired liver function (e.g., alanine aminotransferase [ALT] ≥ 3 times the upper limit of normal [ULN] or bilirubin ≥ 3 times ULN), known active hepatic disease (e.g., hepatitis), or evidence of clinically significant liver disease or other condition affecting the liver that may suggest the potential for an increased susceptibility to hepatic toxicity with oral diclofenac exposure.
• Subject ha
