Objective: To investigate in real-life the conversion from chronic migraine (CM) to episodic migraine (EM), specifically to EM with High-Frequency (HFEM: 8-14 monthly migraine days, MMDs), Medium-Frequency (MFEM, 4-7 MMDs), and Low-Frequency EM (LFEM, 0-3 MMDs), and its persistence during 1 year of treatment with galcanezumab. Methods: Consecutive CM patients treated with galcanezumab completing 1 year of observation were enrolled. We collected data on MMDs, pain intensity (Numeric Rating Scale, NRS score), and monthly acute medication intake (MAMI) from baseline (V1) to the 12-month visit (V12). Results: Of the 155 enrolled patients, 116 (around 75%) reverted to EM at every visit and 81 (52.3%) for the entire 1-year treatment. Patients with older onset age (p = 0.010) and fewer baseline MMDs (p = 0.005) reverted more frequently to EM. At V12, 83 participants (53.5%) presented MFEM or LFEM. Patients reverted to MFEM or LFEM for 7 months (25th 1, 75th 11). The medication overuse discontinuation rate at V12 was 82.8% and occurred for 11 months (25th 8, 75th 12). From baseline to V12, the MAMI decreased by 17 symptomatic drugs (p < 0.000001) while the NRS score reduced by almost 2 points (p < 0.000001). A consistent transition to EM for the entire treatment year was observed in 81 (52.3%) patients. Discussion: The 1-year GARLIT experience suggests that more than half of CM patients treated with galcanezumab persistently reverted to EM in real life. Trial registration: ClinicalTrials.gov NCT04803513.

Abstract
Objective: To investigate in real-life the conversion from chronic migraine (CM) to episodic migraine (EM), specifically to EM with High-Frequency (HFEM: 8-14 monthly migraine days, MMDs), Medium-Frequency (MFEM, 4-7 MMDs), and Low-Frequency EM (LFEM, 0-3 MMDs), and its persistence during 1 year of treatment with galcanezumab. Methods: Consecutive CM patients treated with galcanezumab completing 1 year of observation were enrolled. We collected data on MMDs, pain intensity (Numeric Rating Scale, NRS score), and monthly acute medication intake (MAMI) from baseline (V1) to the 12-month visit (V12). Results: Of the 155 enrolled patients, 116 (around 75%) reverted to EM at every visit and 81 (52.3%) for the entire 1-year treatment. Patients with older onset age (p = 0.010) and fewer baseline MMDs (p = 0.005) reverted more frequently to EM. At V12, 83 participants (53.5%) presented MFEM or LFEM. Patients reverted to MFEM or LFEM for 7 months (25th 1, 75th 11). The medication overuse discontinuation rate at V12 was 82.8% and occurred for 11 months (25th 8, 75th 12). From baseline to V12, the MAMI decreased by 17 symptomatic drugs (p < 0.000001) while the NRS score reduced by almost 2 points (p < 0.000001). A consistent transition to EM for the entire treatment year was observed in 81 (52.3%) patients.
