BACKGROUND: Fremanezumab has demonstrated to be effective, safe, and tolerated in the prevention of episodic or chronic migraine (CM) in randomized, placebo-controlled trials (RCTs). Real-life studies are needed to explore drug effects in unselected patients in routine circumstances and to provide higher generalizability results. This study explores the effectiveness, safety, and tolerability of fremanezumab in a real-life population of individuals affected by high-frequency episodic (HFEM: 8-14 days/month) or CM.
METHODS: This is a 12-week multicenter, prospective, cohort, real-life study. We considered all consecutive patients affected by HFEM or CM visited at 9 Italian headache centers from 28/07/2020 to 11/11/2020. Eligible patients were given subcutaneous fremanezumab at the doses of 225 mg monthly or 675 mg quarterly, according to their preference. Primary study endpoints were the change in monthly migraine days (MMDs) in HFEM and monthly headache days (MHDs) in CM patients at weeks 9-12 compared to baseline. Secondary endpoints encompassed variation in monthly analgesic intake (MAI), Numerical Rating Scale (NRS), HIT-6 and MIDAS scores, and ≥ 50%, ≥ 75% and 100% responder rates at the same time intervals.
RESULTS: Sixty-seventh number migraine patients had received ≥ 1 subcutaneous fremanezumab dose and were considered for safety analysis, while 53 patients completed 12 weeks of treatment and were included also in the effectiveness analysis. Fremanezumab was effective in both HFEM and CM, inducing at week 12 a significant reduction in MMDs (-4.6, p < 0.05), MHDs (-9.4, p < 0.001), MAI (-5.7, p < 0.05; -11.1, p < 0.001), NRS (-3.1, p < 0.001; -2.5, p < 0.001), and MIDAS scores (-58.3, p < 0.05; -43.7; p < 0.001). HIT-6 was significantly reduced only in HFEM patients (-18.1, p < 0.001). Remission from CM to episodic migraine and from MO to no-MO occurred in 75% and 67.7% of the patients. The ≥ 50%, ≥ 75% and 100% responder rates at week 12 were 76.5%, 29.4% and 9.9% in HFEM and 58.3%, 25% and 0% in CM. Younger age emerged as a positive response predictor (OR = 0.91; 95% CI 0.85-0.98, p = 0.013). Treatment-emergent adverse events were uncommon (5.7%) and mild. No patient discontinued fremanezumab for any reason.
CONCLUSIONS: Fremanezumab seems more effective in real-life than in RCTs. Younger age emerges as a potential response predictor.
