Recruitment & Eligibility

Status: Completed

Sex: Not specified

Target Recruitment: 7

Inclusion Criteria

1. Male and female outpatients 18 to 65 years of age inclusive prior to signing informed consent.
2. At Visit 1, patients must have a history of chronic cluster headache and distinguished from episodic cluster headache as defined by IHS ICHD-3 beta (ICHD-3 2013).
3. Not to be shared with potential patients: During SP II, have a baseline cluster headache attack frequency (based on ePRO vendor eligibility report) of:
[3a] minimum of 8 cluster headache attacks
[3b] maximum of 8 cluster headache attacks per day
Note: a patient with 2 or more consecutive days without an attack during the baseline assessment will be excluded. If a patient fails eligibility due to the occurrence of >8 cluster headache attacks per day, the patient may be considered for rescreen.
4. For patients on preventive treatment for cluster headache, must be on a stable regimen (with stable dose for at least 2 months prior to the start of SP II), which may include verapamil (maximum daily dosage: 480 mg), lithium, melatonin, valproate, gabapentin, and topiramate. Use of any other preventive treatments for cluster headache is not allowed.
5. In the opinion of the investigator, spontaneous remission during the doubleblind treatment phase is not anticipated based on the patient*s history of cluster periodicity.
6. At Visit 1, are able to distinguish cluster headache attacks from other headaches (i.e. tension-type headaches, migraine).
7. Investigator judges the patient as reliable to follow all study procedures, keep all study visits, and be compliant with study requirements.
8. Women of child-bearing potential may participate in the study.
a. Women of child-bearing potential must test negative for pregnancy (based on a serum pregnancy test) at the time of enrollment and must agree to use a reliable method of birth control during the study and for 5 months following the last dose of investigational product.
b. Male patients agree to use a reliable method of birth control during the study and for 5 months following last dose of investigational product.
c. Women not of child-bearing potential are those who are infertile due to surgical sterilization (at least 6 weeks after surgical bilateral oophorectomy with or without hysterectomy or at least 6 weeks after tubal ligation) confirmed by medical history, or menopause.
9. Have not taken any of the following excluded medications or other treatments for cluster headache within the time frame noted:
a. use within 14 days prior to SP II of any of the following: dihydroergotamine or ergot derivatives; gabapentin; lithium; melatonin; methergine; topiramate; valproate; verapamil, opioids
b. use within 30 days prior to SP II of any of the following: systemic or injected corticosteroids; occipital nerve block; any ot her cranial or extracranial nerve block; any neurostimulation treatment.
Note: Patients are allowed to use only the following for acute/abortive treatment for their cluster headache attacks: high-flow oxygen; oral triptans, sumatriptan subcutaneous injection; sumatriptan nasal spray; zolmitriptan nasal spray; acetaminophen and NSAIDs.
10. Throughout the study (Informed Consent through Visit 24), agree to refrain from the use of drugs of abuse per United States Federal Guidelines such as, but not limited to, cannabinoids, cannabis, psilocybin (mushrooms), LSD and 2-bromo-LSD.
11. Agree not to post any personal medical data related to the study or i

Exclusion Criteria

13. Current enrollment in, or discontinuation within the last 30 days prior to Visit 1 from, a clinical trial involving any investigational drug or device, or concurrent enrollment in any other type of medical research judged not to be scientifically or medically compatible with this study.
14. Current use or any prior exposure to any CGRP antibody (including LY2951742), any antibody to the CGRP receptor, or antibody to nerve growth factor (NGF) including past participation in a clinical trial investigating CGRP, CGRP receptor, or NGF antibodies.
15. Patients who are taking other therapeutic antibodies or are expected to take during the course of the study (for example, adalimumab, infliximab, trastuzumab, bevacizumab, etc.). Prior use of other therapeutic antibodies is allowed if an adequate wash-out has occurred (*5 half-lives) prior to SP II.
16. Any of the following headache-related or pain-related conditions are exclusionary:
a. Current diagnosis of Medication Overuse Headache as defined by ICHD-3 beta within 3 months prior to Visit 3. Note: daily triptan use for daily cluster headache attacks is allowed provided it is not resulting in an MOH of some other headache type.
b. Lifetime history of migraine variants that could implicate or could be confused with ischemia; specifically, hemiplegic (sporadic or familial) migraine, ophthalmoplegic migraine, and basilar-type migraine defined by ICHD-3 beta.
c. Are taking indomethacin and/or are suspected of having another distinct trigeminal autonomic cephalalgia such as hemicrania continua, paroxysmal hemicrania, or shortlasting unilateral neuralgiform headache attacks (SUNCT or SUNA).
d. Have other significant pain problem that might confound the study assessments in the opinion of the investigator.
17. Patients who have taken botulinum toxin type A or B, that was administered in the head or neck area, within 4 months of SP II for treatment of cluster headache or other disorders, or for cosmetic use.
18. Any (lifetime) history of deep brain stimulation.
19. Evidence of significant active or unstable psychiatric disease by medical history, such as bipolar disorder, schizophrenia, personality disorders, or other serious mood or anxiety disorders.
Note: Patients with major depressive disorder or generalized anxiety disorder, whose
disease state is considered stable and expected to remain stable throughout the course of
the study, in the opinion of the investigator, may be considered for inclusion if they are
not on excluded medication(s).
20. Are considered by the investigator to be at significant risk for suicide.
21. Women who are pregnant or nursing.
22. Any of the following cardiovascular-related conditions are exclusionary:
a. Prior to Visit 3 (randomization), have ECGs showing acute abnormalities of:
i. evidence of delayed ventricular repolarization including but not limited to a corrected QT (Bazett*s QT interval [QTcB]) interval >470 msec for women an >450 for men, and/or
ii. ii. evidence of atrioventricular (AV) depolarization of PR>220, or conduction delay of QRS>120, and/or
iii. iii. evidence of ischemia or any of the qualitative findings indicative of ST or J-point elevation, excluding those findings consistent with early repolarization (nonischemic).
b. History of myocardial infarction (MI), unstable angina (UA), percutaneous coronary intervention, coronary artery bypass graft, or deep vei
