Study summary

The main purpose of this study is to evaulate the efficacy and safety of galcanezumab in participants 6 to 17 years of age for the preventive treatment of episodic migraine. The primary objective is to demonstrate the superiority of galcanezumab versus placebo in the reduction of monthly migraine headache days across the 3-month double-blind treatment period.

Read the detailed description

The study has two parts which enroll separately from each other such that participants may choose to participate in either but not both: the main study and a study addendum.

  • The main study includes a 3-month, randomized, double-blind treatment period in which participants receive either galcanezumab or placebo, followed by a 9-month open-label extension in which all participants receive galcanezumab.
  • The study addendum is a stand-alone study of galcanezumab pharmacokinetics and safety in a group of participants separate from those in the main study. The study addendum includes a 5-month evaluation period after a single injection of galcanezumab, followed by a 9-month open-label extension.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Have a diagnosis of migraine with or without aura as defined by the IHS ICHD-3 guidelines (1.1 or 1.2 according to ICHD-3 [2018]), with a history of migraine headaches of at least 6 months prior to screening.

Exclusion criteria

Exclusion Criteria:

  • Participants who are taking, or are expected to take, therapeutic antibodies during the course of the study (adalimumab, infliximab, trastuzumab, bevacizumab, etc.). Prior use of therapeutic antibodies is allowed if that use was more than 12 months prior to baseline.
  • Known to monoclonal antibodies or other therapeutic proteins, or to galcanezumab or its .
  • Current use or prior exposure to galcanezumab, another CGRP antibody, or CGRP receptor antibody, including those who have previously completed or withdrawn from this study or any other study investigating a CGRP antibody.
  • History of IHS ICHD-3 diagnosis of new daily persistent headache, cluster headache or migraine subtypes including hemiplegic (sporadic or familial) migraine and migraine with brainstem aura (previously basilar-type migraine).
  • History of significant head or neck injury within 6 months prior to screening; or traumatic head injury at any time that is associated with significant change in the quality or frequency of their headaches, including new onset of migraine following traumatic head injury.
  • Participants with a known history of intracranial tumors or developmental malformations including Chiari malformations.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2018 to primary completion in Nov 2025, 92 months.

Of 21 industry-sponsored phase 3 interventional studies under Headache, half reached primary completion within 17 months of starting (the median); a quarter within 13 and three quarters within 31. This study's 92 months is above that.

Counting every sponsor, half of 30 studies reached it within 18 months; a quarter within 13 and three quarters within 47.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 26, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
