Brief Summary
Cluster headache is a primary headache condition characterized by clusters of one-sided, high-intensity pain attacks. The headache may be episodic or chronic. Treatment options are limited and their effects unsatisfactory. An important nerve pathway involved in the pain attacks has a switching station at the sphenopalatine ganglion (SPG) located in the depth of the facial bones. SPG is a known therapy target for cluster headache. The area can be identified on CT images, but is difficult to access due to its location. Thus, the Multiguide navigation system has been developed to enable precise delivery of the drugs that target SPG activity. In Trondheim, two phase 1 / Phase 2 study have been carried out using botulinum toxin A (Botox®) against SPG in patient with chronic cluster headache and chronic migraine. The results indicate that such a treatment strategy is safe and beneficial. The current study is a randomized, placebo-controlled, triple-blinded study to investigate whether precise single-injection of botulinum toxin A reduces the frequency of attacks in chronic cluster headache .

Outcome Measures
Primary Outcomes (1)
Difference in change from baseline week 5-8 in mean number of cluster headache attacks per week at weeks 5-8 post-intervention in the treatment group versus the placebo group
Change from baseline to weeks 5-8 post-intervention in number of cluster headache attacks per week in the active group versus the placebo group. The number of cluster headache attacks is collected in a headache diary.
week 5 through week 8 in the post-injection period
Secondary Outcomes (7)
Difference in occurrence of adverse events (AEs) and serious adverse events (SAEs) in the active group versus the placebo group
week 1 through week 12 in the post-injection period
Difference in change from baseline week 5-8 in mean number of cluster headache attacks per week during weeks 9-12 post-intervention in the active group versus the placebo group
week 9 through week 12 in the post-injection period
Difference in change from baseline week 5-8 in mean number of cluster headache attacks per week at weeks 5-8 post-intervention in the active group versus the placebo group, in the prespecified subgroups
week 5 through week 8 in the post-injection period
Difference in change from baseline week 5-8 in mean number of cluster headache attacks per week during weeks 9-12 post-intervention in the active group versus the placebo group, in the prespecified subgroups
week 9 through week 12 in the post-injection period
Difference in the number of therapeutic responders in the active group versus the placebo group.
week 5 through week 8 in the post-injection period

Eligibility Criteria
You may qualify if:
- Informed and written consent.
- Male or female, 18-85 years of age
- Headache attacks fulfilling the International Classification of Headache Disorders (ICHD) III criteria for chronic cluster headache (CCH) 3.1.2.
- Dominant headache laterality with ≥ 80% of cluster headache attacks on one side.
- The condition is pharmacologically refractory defined as suboptimal effect or intolerable side effects or contraindication for verapamil or lithium or suboccipital steroid injection.
- Subject agrees to maintain current preventive headache medication regimens (no change in type, frequency, or dose) during the whole study period.
- Subject is able to differentiate concomitant headaches from cluster headache.
- In case of women of childbearing potential (WOCBP) they have to be using highly effective contraception in a period of 4 weeks after injection.
- Ability to understand study procedures and to comply with them for the entire length of the study
You may not qualify if:
- Subject has had a change in type, dosage or dose frequency of preventive headache medications ≥ two weeks prior to baseline/screening or 5 half-lives, whichever is longer.
- Subject currently treated with occipital nerve stimulation, deep brain stimulation or other implantable device, that have changed parameters in the last month, or are unable to keep parameters stable throughout the study.
- Current or previous treatment with implanted medical devices targeting the SPG
- Subject has had a change in type, dosage or dose frequency of preventive headache medications during the baseline period, eg. prior to IMP administration.
- Non-responder to both oxygen and triptan.
- Participation in a clinical study of a new chemical entity or a prescription medicine within 2 months before study drug administration or 5 half-lives, whichever is longer.
- Subject is currently participating or has participated in the last 3 months in another clinical study in which the subject has, is, or will be exposed to an investigational or non-investigational drug or device.
- Allergy or hypersensitivity reactions to marcaine, lidocaine, xylocaine, adrenaline, any botulinum toxin or similar substances.
- Abuse of drugs or alcohol.
- Use of opioids for ≥10 days per month.
- Treatment with pharmacological substances that may interact with BTA (aminoglycosids, spectinomycin, neuromuscular blockers, both depolarizing agents (such as succinylcholine) or non-depolarizing (tubocurarine derivates), lincosamides, polymyxins, quinidine, magnesium sulfate or anticholinestases.).
- Pregnancy or breastfeeding in the study period
- Subject has undergone facial surgery in the area of the pterygopalatine fossa or zygomaticomaxillary buttress ipsilateral to the planned injection site that, in the opinion of the Investigator, may lead to an inability to properly conduct the procedure.
- Facial anomaly or trauma which renders the procedure difficult.2
- Subject currently has an active oral or dental abscess or a local infection at the site of injection based on present symptoms.
