Key clinical point: In patients with episodic migraine (EM) or chronic migraine (CM), erenumab treatment interruption was associated with increased monthly migraine days (MMD) and worsening of migraine disability; these effects ameliorated on treatment restart.
Major finding: After erenumab treatment interruption for 3 months, the number of monthly migraine days (MMD) increased from 6.1 to 10.9 days for patients with EM and from 11.4 to 16.8 days for patients with CM; the modified Migraine Disability Assessment scores (mMIDAS) also worsened during this period. Both MMD and mMIDAS scores improved upon restarting treatment.
Study details: This interim analysis of the 24-month, multicentric, non-interventional observational study included 172 patients with CM or EM who received erenumab and underwent treatment interruptions on average 11.2 months after initiation, with interruptions lasting for a mean duration of 4 months.
Disclosures: This study was funded by Novartis Pharma Schweiz AG. Four authors declared being full-time employees of Novartis Pharma Schweiz AG, and others declared having ties with various sources, including Novartis.
