Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change from baseline in monthly number of headache days assessed using patient-reported daily headache diary | Baseline and Month 1 | Change from baseline in the number of monthly headache days recorded using a patient-reported daily headache diary. A headache day is defined as any calendar day with headache lasting ≥4 hours or requiring acute medication. |
| Secondary | Change from baseline in pain intensity measured using the Visual Analog Scale (VAS) for pain | Baseline and Month 3 | Change from baseline in pain intensity measured using a 10-cm Visual Analog Scale (VAS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates worst imaginable pain. |
| Secondary | Change from baseline in total monthly headache duration (hours) assessed using patient-reported daily headache diary | Baseline and Month 3 | Change from baseline in total monthly headache duration (hours), calculated from patient-reported daily headache diaries as the cumulative number of hours with headache per month. |
| Secondary | Change from baseline in headache-related disability measured using the Migraine Disability Assessment (MIDAS) questionnaire | Baseline and Month 3 | Change from baseline in headache-related disability measured using the Migraine Disability Assessment (MIDAS) questionnaire. Scores range from 0 to 270, with higher scores indicating greater disability. |
| Secondary | Incidence of treatment-emergent adverse events (TEAEs) | Up to Month 3 | The number and proportion of participants experiencing treatment-emergent adverse events (TEAEs), assessed through clinical evaluation and patient self-report. Adverse events were categorized by severity and relationship to the intervention. |
