Assessment and characteristics of Erenumab therapy on migraine management

BackgroundMigraine is one of the neurological diseases that have a negative impact on subjects’ productivity and daily activity of patients. Introducing monoclonal antibodies as a valuable option for resolving the persistent problem of migraine is still under investigation. The current study aimed to evaluate the efficacy and safety profile related to Erenumab.MethodsA prospective study for clinical data collection and analysis from recruited therapy-refractory migraine subjects were carried through 6 months for each subject. All subjects received Erenumab 70 mg monthly. Each patient provided the clinical data monthly starting from 0 months and for the next 6 months. Migraine disability assessment (MIDAS) questionnaire was used for evaluation of the Erenumab efficacy every 3 months. In addition, data regarding adverse effects, migraine triggers, and the impact of previous COVID-19 on migraine severity were collected and analyzed.ResultsNinety subjects were recruited in the study. Erenumab injections resulted in a significant (p < 0.001) reduction in MIDAS score in the 3rd month compared with baseline, also this significance was continuous in the 6th month. In contrast, there was no significant difference in the 6th month compared with the 3rd. Previously infected COVID-19 subjects showed a higher severity of migraine attacks compared with non-infected subjects. Skin redness and local pain were the most common adverse effects 63.3%, 47.77% respectively associated with Erenumab.ConclusionUsing Erenumab therapy showed a great beneficial impact regarding the reduction of migraine-related disabilities. COVID-19 was related to the increased severity of migraine attacks.
