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.
