Treatment satisfaction with calcitonin gene-related peptide monoclonal antibodies as a new patient-reported outcome measure: A real-life experience in migraine

Background To evaluate treatment satisfaction with galcanezumab as a patient-reported outcome measure (PROM) in migraine. Methods Patients with >= 8 headache days/month that had failed at >= 3 medications were included. Demographic and medical history were collected. Patient ' s satisfaction (effectiveness, safety, convenience, and global satisfaction [GS]) was assessed by the Treatment Satisfaction Questionnaire for Medication version 1.4 (TSQM-1.4 (c)). Results We included 30 patients with migraine (76.7% chronic migraine). After 12 weeks of galcanezumab treatment, median monthly headache days (MHDs) decreased 11.5 (IQR 14.0) and median monthly migraine days (MMDs) 9.0 (IQR 7.5); at 24 weeks, the change was 15.0 (IQR 12.0) and 8.0 days (IQR 6.0). HIT-6 score decreased from 68.0 (IQR 7.5) to 54.0 (IQR 9.5) at 12 weeks (p < .001) and to 52.0 (IQR12.0) at 24 weeks (p < .001) and MIDAS from 60.0 (IQR 62.7) to 25.5 (IQR 41.2, p = .004) and 7.0 (IQR 18.5, p < .001), respectively. TSQM-1.4 (c) at 12 weeks was higher compared to other preventive therapy in effectiveness (80.6/50.4, p < .001), convenience (83.3/66.7, p = .001), and GS (78.6/50.0, p < .001). These rates of satisfaction were similar at 24 weeks of galcanezumab treatment. Reductions in HIT-6 (r = -.444, p = .014), MIDAS (r = -.423, p = .020), MMDs (r = -.515, p = .004), and MHDs (r = -.477, p = .008) were associated significantly with GS at 12 weeks. This correlation was significantly associated with changes in HIT-6 and MHDs at 24 weeks. Conclusions The results of this study suggest that migraine patients receiving galcanezumab are significantly more satisfied compared to other preventive therapies, associating treatment GS with meaningful reductions in frequency, impact, and disability caused by migraine.
