A new study shows that the monoclonal antibody fremanezumab is effective for migraine prophylaxis, even in patients who have failed to respond to multiple preventive treatments. However, not all patients benefit from this treatment, and detailed investigation of non-responders could help to identify additional pharmacological targets and increase the number of responders.
