Correlation of Calcitonin Gene-Related Peptide (CGRP) Levels in Saliva With the Evolution of an Attack of Migraine
Study Details
Study Description
Brief Summary
To assess CGRP levels in saliva through the evolution of migraine.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
|
Detailed Description
The release of CGRP is assumed to be initiated early in the migraine process and increases as the headache intensifies. Levels of CGRP will be measured during the premonitory, mild, moderate, and severe phases of a single migraine attack and compared to the baseline value determined when the subject was headache free. Understanding of the clinical evolution of migraine CGRP release may have significant implications in acute treatment.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| 1 group, usual acute triptan treatment
|
Other: subjects personal triptan
Subjects will treat 1 migraine attack with their usual triptan
|
Outcome Measures
Primary Outcome Measures
- Compare baseline levels of CGRP measured during a migraine free period to those during the 4 phases (prodrome, mild, mod., severe) of migraine. [baseline,prodrome, mild, mod., severe, 4 hrs. post dose]
Secondary Outcome Measures
- CGRP levels compared to no headache and as function of prodrome symptoms, prediction of mod/sev headache; compare prodrome symptoms to those reported at screening to pre-tx,tx,post tx. [screening, prodrome, pre-treatment, mild, moderate tosevere, post treatment]
