TOGETHER: Tandem OnabotulinumtoxinA Galcanezumab Emerging Therapeutic Headache Elimination Research Study
Study Details
Study Description
Brief Summary
This is a multicenter, double-blind, placebo-controlled study assessing the effectiveness of Galcanezumab as an add-on therapy for Migraine participants on a stable migraine prophylaxis regimen including Botox with or without one other migraine prophylaxis agent (BMPT), who have persistent unmet need. The study population will consist of approximately 150 participants ages 18-65 who report at least a 30% reduction in monthly migraine days from BMPT and still experience an average of ≥ 6 migraine days per month, following International Classification of Headache Disorders (ICHD-3) criteria. Subjects should be stable on at least 2, but no more than 8, consecutive injection cycles of Botox. Overall migraine day reduction will be assessed in the participants based on participant self-report (via daily electronic diaries) and medical record review.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Galcanezumab + BMPT 240 mg of galcanezumab will be administered once as a loading dose at Visit 2, followed by monthly doses of 120 mg at Visits 3 and 4. All participants will be required to continue BMPT. For consistency purposes visit 2/ randomization should be scheduled within +/- 3 days of subjects next Botox administration as part of BMPT. |
Drug: Galcanezumab
Galcanezumab is a calcitonin-gene related peptide antagonist indicated in adults for the preventive treatment of migraine and the treatment of episodic cluster headache.
|
| Placebo Comparator: Placebo + BMPT • Galcanezumab matching placebo will be administered at Visits 2, 3 and 4. |
Other: Placebo
Galcanezumab' placebo. This is the same vehicle as the study intervention formulation but does not contain active galcanezumab-gnlm.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Willing to participate and sign informed consent;
-
Ability to understand informed consent and study procedures, including ability to use the electronic Daily Headache Diary;
-
In good general health based on investigator's judgment;
-
Must be between 18 to 65 years of age, inclusive, at time of Visit 1;
-
Reports having an average of > 6 migraine days per month, after at least 2 and up to 8 consecutive treatments of onabotulinumtoxinA at the time of screening, meeting the diagnostic criteria listed in the International Classification of Headache Disorders (ICHD-3);
-
Subject reports a > 30% decrease in the number of monthly migraine days from the onset of treatment with Botox (onabotulinumtoxinA);
-
Has a score on the Migraine Disability Assessment Questionnaire (MIDAS) >11 at screening;
-
During the baseline period reports >6 migraine days per month and < 25 days of head pain;
-
Onset of migraine before age 50;
-
Able to differentiate migraine from other primary headache types allowed in the study (e.g., tension-type headache);
-
Agrees to present for screening 28 days (± 3 days) prior to next anticipated Botox treatment, and to continue BMPT documented at screening for the rest of the study period. Subjects unwilling or unable to continue BMPT will not proceed through the study.;
-
Women may be included only if they have a negative pregnancy test at screening and baseline, are sterile, or postmenopausal. Women of childbearing potential (WOCBP) whose male partners are potentially fertile (i.e., no vasectomy) must use highly effective birth control methods for the duration of the study (i.e., starting at screening). Definitions of WOCBP, sterile and postmenopausal women, male contraception, and highly effective and acceptable birth control methods are to be determined based on investigator's judgment;
-
Demonstrated > 85% compliance the electronic Daily Headache Diary during 28-day run-in period (as defined as data entry on a minimum of 24 of the first 28 days of run-in period).
Exclusion Criteria:
