Lundbeck's VYEPTI Hits 60% Improvement in Phase IV THRIVE Trial
Valby, Denmark – October 01, 2026 -- H. Lundbeck A/S reported that 60% of participants in its Phase IV THRIVE trial achieved 'much improved' or 'very much improved' status on a standardized patient scale after switching to eptinezumab, marketed as VYEPTI, following an inadequate response to a prior CGRP-targeting preventive migraine therapy.
Trial enrolled 164 adults who had failed one prior CGRP preventive treatment
The 24-week, open-label, multicenter trial (NCT06701526) was conducted in the United States and enrolled 164 adults with at least eight monthly migraine days who had previously used either a subcutaneous anti-CGRP monoclonal antibody or a preventive gepant, but had not received eptinezumab. Participants started on 100 mg of eptinezumab, escalating to 300 mg at week 12, with 147 receiving both infusions; 84% (138/164) completed the trial.
