Long-Term Extension Study With Eptinezumab as Preventive Treatment in Participants With Migraine in Japan

January 13, 2026 updated by: H. Lundbeck A/S

Interventional, Open-label, Fixed-dose, Long-term Extension Study to Evaluate Safety of Eptinezumab as Preventive Treatment in Patients With Migraine

This study is an open label extension study, which means that the participants from the Lead-in Study 19140A (NCT04921384) can join this study, if they meet the study Eligibility Criteria, and continue to receive the study drug eptinezumab. The main goal of this study is to investigate long-term safety and tolerability of eptinezumab in Japanese migraine participants.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Key Inclusion Criteria:

  • The participant has completed the Primary Outcome Visit (Visit 5) of the lead-in Study 19140A immediately prior to enrolment into this study.
  • The participant is indicated for 60-week preventive treatment of chronic migraine with eptinezumab according to the clinical opinion of the investigator.

Key Exclusion Criteria:

  • The participant has a serious adverse event (SAE) or a moderate or severe ongoing AE from the Lead-In study considered a potential safety risk by the investigator.
  • The participant has a clinically relevant change in vital signs or electrocardiogram (ECG) from the Lead-In study considered a potential safety risk by the investigator.
  • The participant has a disease or takes medication that could, in the investigator's opinion, interfere with the assessments of safety, tolerability, or efficacy, or interfere with the conduct or interpretation of the study.

Other inclusion and exclusion criteria may apply.
