What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants Who Were Pain Free at 2 Hours Post-dose
Participants were evaluated (self-assessment) for pain intensity by using a 4-point rating scale: 0=none, 1=mild, 2=moderate, and 3=severe. Participants with pain-free response were considered as those who had a reduction in migraine headache pain from moderate (score=2) or severe (score=3) at baseline to none (score=0) post-treatment, without the use of rescue medication (additional medication taken by participants for the treatment of migraine pain or associated symptoms) prior to or at 2 hours post-dose.
Measured: 2 hours after single dose of double-blind treatment (Randomization through Week 13)
Secondary outcomes (10)
Number of Participants Sustained Pain-free From 2-24 Hours
Participants with sustained pain-freedom were defined as those with pain-freedom at 2 hours post-dose that was maintained up to 24 hours post-treatment without the use of rescue medication.
Measured: 2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)
Number of Participants Photophobia-free at 2 Hours Post-dose
The number of participants who did not have photophobia (sensitivity to light) at 2 hours post dose was analyzed.
Measured: 2 hours after single dose of double-blind treatment (Randomization through Week 13)
Number of Participants Phonophobia-free at 2 Hours Post-dose
The number of participants who did not have phonophobia (sensitivity to sound) at 2 hours post dose was analzyed.
Measured: 2 hours after single dose of double-blind treatment (Randomization through Week 13)
Number of Participants Pain-free at 1 Hour Post-dose
Participants with a pain-free response at 1 hour post-dose were considered as those who had a reduction in migraine headache pain from moderate (a score of 2) or severe (a score of 3) at baseline to none (a score of 0) post-treatment, without the use of rescue medication prior to or at 1 hour post dose.
Measured: 1 hour after single dose of double-blind treatment (Randomization through Week 13)
Number of Participants Sustained Photophobia-free From 2-24 Hours
Participants with sustained freedom from photophobia were those with an absence of photophobia (sensitivity to light) from 2 to 24 hours post-dose without the use of rescue medication.
Measured: 2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)
Number of Participants Sustained Phonophobia-free From 2-24 Hours
Participants with sustained freedom from phonophobia were those with an absence of phonophobia (sensitivity to sound) from 2 to 24 hours post-dose without the use of rescue medication.
Measured: 2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)
Number of Participants Sustained Nausea-free From 2-24 Hours
Participants with sustained freedom from nausea were those with an absence of nausea from 2 to 24 hours post-dose without the use of rescue medication.
Measured: 2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)
Number of Participants Who Used Rescue Medication From 2 to 24 Hours Post Dose
Rescue medication was defined as an additional medication taken by participants for the treatment of migraine pain or associated symptoms within 24 hours of dosing with investigational product. Permitted rescue medications included oral naproxen sodium (maximum 15 mg/kg), oral over-the-counter pain reliever, and anti-emetics. This outcome measure included only participants who rescued from 2 to 24 hours post-dose, inclusive.
Measured: 2 to 24 hours after single dose of double-blind treatment (Randomization through Week 13)
Number of Participants Who Used Their First Dose of Rescue Medication Through the Indicated Time Points
Rescue medication was defined as an additional medication taken by participants for the treatment of migraine pain or associated symptoms within 24 hours of dosing with double-blind treatment. In addition to participants who rescued from 2 to 24 hours post-dose, inclusive, this outcome measure also included nine protocol violators who rescued < 2 hours post-treatment.
Measured: Dosing to 24 hours after single dose of double-blind treatment (Randomization through Week 13)
Number of Participants Nausea-free at 2 Hours Post-dose
The number of participants who did not have nausea at 2 hours post dose was analzyed.
Measured: 2 hours after single dose of double-blind treatment (Randomization through Week 13)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Sumatriptan and Naproxen Sodium in people with Migraine Disorders, run by GlaxoSmithKline at 79 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 0 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 79 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 9 May 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants Who Were Pain Free at 2 Hours Post-dose (time frame: 2 hours after single dose of double-blind treatment (Randomization through Week 13)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00843024, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jan 2017.
