Investigators
Eligibility Criteria
Inclusion Criteria
- •Age from ≥22 years old.
- •Subject has been diagnosed with chronic cluster headache according to the 2013 ICHD, 3rd edition (beta version), criterion 3.1.
- •Subject reports a minimum of 4 cluster attacks per week on the side of their dominant headache laterality. Subjects who report more than 8 attacks per day or attack duration of less than 30 minutes (untreated or unsuccessfully treated) must have been tested to rule out other forms of trigeminal autonomic cephalalgias.
- •Both subject and physician judge previously or currently used preventive and/or acute cluster headache treatment to be inadequate.
- •Subject is able to distinguish cluster attacks from other headaches (i.e., migraine, tension-type headaches).
- •Subject agrees to not use therapy involving TENS or magnetic field treatment while the Neurostimulator is implanted.
- •Subject agrees to not participate in supplemental or alternative therapy, including acupuncture and spinal manipulation, from Study Enrollment through the end of the Experimental Period of the study.
- •Subject agrees to maintain current preventive headache medication regimens (no change in type, frequency, or dose) - except to manage tolerability - from Study Enrollment through the Experimental Period of the study.
- •Subject agrees not to use any acute medications, including oxygen therapy, for their treatable cluster attacks during the Experimental Period until after they have used SPG stimulation therapy for at least 15 minutes.
- •Subject has had a dental examination and cleaning in the past six (6) months.
Exclusion Criteria
- •Subject's overall health, age and/or comorbidities place subject at high risk for complications from surgery and/or general anesthesia.
- •Subject has had a change in type, dosage or dose frequency of preventive headache medications \< one (1) month prior to study enrollment
- •Subject has been diagnosed with any other form of Trigeminal Autonomic Cephalalgias (e.g., paroxysmal hemicrania, SUNCT, etc.) or has a history of trigeminal neuralgia.
- •Subject has undergone facial surgery in the area of the pterygopalatine fossa or zygomaticomaxillary buttress ipsilateral to the planned implant site that, in the opinion of the Investigator, may lead to an inability to properly implant the Neurostimulator.
- •Subject currently has an active oral or dental abscess or an active maxillary sinus infection based on present symptoms.
- •Subject has been treated with therapeutic radiation to the facial region.
- •Subject has been diagnosed with any major infectious processes such as osteomyelitis, or primary or secondary malignancies involving the face that have been active or required treatment in the past six (6) months.
- •Subject has other significant pain problem(s) that, in the opinion of the Investigator, might confound the study assessments.
- •Subject is a woman of childbearing potential who is pregnant, nursing, or not using contraception.
- •Subject is currently participating or has participated in the last month in another clinical study in which the subject has, is, or will be exposed to an investigational or non-investigational drug or device.
Outcomes
Primary Outcomes
Primary Safety
Time Frame: One year post-implant
Characterization of all serious adverse events in all subjects who undergo an implantation procedure, through the completion of the Open Label Period.
Primary Efficacy
Time Frame: 28 weeks post-implant
Compared between the two study arms: Proportion of stimulation-treated ipsilateral cluster attacks that achieve pain relief at 15 minutes following the start of stimulation without the use of acute medications prior to that time point.
Secondary Outcomes
- Secondary Efficacy(28 weeks post-implant)
