What the trial was testing
The trial enrolled 485 patients with migraine. The study was sponsored by H. Lundbeck A/S and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
People treated with eptinezumab reached complete pain freedom in 4 hours versus 9 hours with the dummy treatment.
JAMA · 2021 · NCT04152083
These findings — that half the time it took with dummy treatment to reach complete headache relief — were published in the JAMA and represent the headline result of the study.
Researchers tracked outcomes across 485 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with migraine, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Eptinezumab is FDA-approved for preventing migraines, but this study looked at using it during an active attack. The results showed it worked faster than dummy treatment, but it requires an IV infusion which isn't practical for most migraine attacks. Talk to your doctor about approved migraine treatments that work best for your situation.

A Study to Evaluate the Efficacy and Safety of Elismetrep (K-304) in the Acute Treatment of Migraine
This is a double-blind, randomized, multicenter, outpatient evaluation of the efficacy, safety, and tolerability of elismetrep, as compared with placebo, in the acute treatment of migraine.
High-field MR Imaging in Migraine, Visual Snow and Epilepsy
In this project, the aim is to recruit patients with drug resistant epilepsy and those suffering from migraine. Interestingly, patients suffering from epilepsy are also more often reporting to suffer from migraine. The pathobiology is understudied, but it is believed that both etiologies results from brain networks changes. A clinical certified 7T Terra Siemens scanner will be employed to assess in all participants (including healthy controls) how the microstructure differs in disease specific areas. Patients will further be clinically assessed as well as undergo questionnaires. Migraine is also a common comorbidity to visual snow syndrom and has been shown to impact similar brain regions. However, the pathophysiology is still understudied and a better understanding of the two diseases is needed.
