About
This is a pharmacokinetic (PK) study designed to investigate a combination product containing sumatriptan succinate and naproxen sodium administered at 3 single doses (10mg sumatriptan/60mg naproxen sodium, 30mg sumatriptan/180mg naproxen sodium, 85mg sumatriptan/500mg naproxen sodium) in adolescent migraine patients. The same doses will be also administered to a group of healthy volunteer (HV) adult subjects and the PK parameters will be compared between these two groups and between doses.
Full description
This will be an open label, single dose, randomised, parallel group study. Approximately 27 adolescent patients with migraine and 27 healthy volunteer (HV) adult subjects will be enrolled so that a total of 24 evaluable subjects complete in each group. The treatment procedures for these two groups are almost identical but some flexibility has been allowed for the timing of some of the PK samples in adolescents. All subjects will be required to attend a screening visit within 28 days prior to the first dose of study medication. Each subject will participate in one dosing session with one of the 3 doses of sumatriptan/ naproxen sodium. Sequential PK samples will be collected through 48 hours after dosing and the PK parameters will be compared between these two groups and between doses.

Inclusion criteria
Adolescent Migraine Subjects
- Subject has history of migraine with or without aura.
- Subject has history suggestive of typical migraine attacks with duration of about 2 or more hours.
- Subject has at least 2, but not more than 8, migraine attacks per month in each of the 2 months prior to the screening visit.
- Subject has at least a 6-month history of moderate to severe migraine attacks, sufficient to establish a definitive diagnosis of migraine.
- Subject is able to distinguish migraine from other headaches (e.g., tension-type headaches).
All subjects
-
Subject must fall between following age ranges:
- Adolescent subjects between 12 and 17 years old inclusive at the screening visit and 18 years at dosing.
- Adult healthy subjects between 18 to 55 years old inclusive at the screening visit.
-
Subject BMI and weight must fall between the following:
- Adolescent subject body weight less than 33.4 kg and a healthy weight using age-based BMI range 5th-85th percentile (see Appendix 4).
- Adult healthy subject BMI within the range 18-32 kg/m2 inclusive
-
Healthy as determined by a responsible physician, based on a medical evaluation including medical history, physical examination, laboratory tests and ECG. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
-
A female subject is eligible to participate if she is of:
- Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MlU/ml and estradiol < 40 pg/ml (<140 pmol/L) is confirmatory]. For younger adolescent migraine subjects, non-childbearing potential also defined as premenarchal is a young female who has not yet entered puberty as evidenced by lack of breast development of palpable glandular breast tissue. Females on hormone replacement therapy and whose menopausal status is in doubt will be required to use one of the contraception methods in Section 8.1 if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment. For most forms of HRT, at least 2-4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.]
- Child-bearing potential and agrees to use one of the contraception methods listed in Section 8.1 for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects who are sexually active must agree to use contraception until 5 day after dosing.
-
Subjects must be able to read and write English or Spanish and give written informed consent as follows:
- Adult: subject is willing and able to provide written informed consent
- Adolescent: subject is capable of giving written assent with an informed consent from their parents or legal guardian, which includes compliance with the requirements and restrictions listed in the consent form.
-
Eligible subjects should meet the QT criteria as follows:
- Adolescent: QTcB or QTcF <450 msec; and without Bundle Branch Block
- Adult: QTcB or QTcF<450 msec; or QTc <480 msec in subjects with Bundle Branch Block.
Exclusion criteria
Adolescent Migraineur Subjects
- Subject has ≥15 headache days per month in total, retinal, basilar or hemiplegic migraine or secondary headaches.
- Subject is experiencing a migraine attack or has experienced a migraine attack within 24 hours of dosing.

- Adolescent BP >/= 95 percentile adjusted for age, height and gender (Appendix 4).
