3. Migraine attack frequency of 2-10 attacks per month with no more than 20 headache days
per month on average over the last 3 months
4. Willingness, ability, and commitment to participate in baseline and follow-up
evaluations without concurrent participation in another clinical trial.
5. Signed subject informed consent form.
6. Typical untreated migraines are historically at least moderate to severe, by patient

least 3 months prior to study entry and must remain on the same therapy with stable
dosing during the study.

device for audio and/or video contacts
Exclusion Criteria:
1. Failure to meet any of the inclusion criteria.

3. Pregnancy or intent to become pregnant over the course of the study.
4. Inability to distinguish migraine from other primary headache phenotypes.
5. Presence of any condition or state that would prevent the subject from sitting or
lying down comfortably during the course of the treatment (up to at least 30 minutes).
6. Unable or unlikely to follow instructions for proper use of the device including
connection of the phone to a wireless connection.
7. Personal or family affiliation as a service provider - e.g., employee, contractor,
consultant, or volunteer (other than as a subject in a previous clinical trial) - with
a migraine treatment device company.
8. Subjects with vital sign values that are outside acceptable norms.
1. Systolic blood pressure > 160 mmHg
2. Diastolic blood pressure > 100mmHg
3. Resting heart rate >100 beats per minute
4. Temperature > 100.5°F
9. History of significant vestibular, auditory or external ear diagnoses or symptoms,
including but not limited to Meniere's disease; endolymphatic hydrops; complete loss
of hearing in either ear, significant hearing loss in either ear that requires a
hearing aid or has deteriorated noticeably over the past year; previous ear surgery
(including tympanostomy tubes); superior canal dehiscence, current or ongoing
dizziness or vertigo, perforated or compromised tympanic membrane, external auditory
canal obstruction which cannot be removed prior to treatment
10. Current diagnosis or significant prior diagnosis of secondary headache (except MOH
headache), cerebral aneurysm, intracranial hemorrhage, brain tumor, chiari
malformation, or currently active occipital neuralgia that in the investigator's
opinion would interfere with study-related assessments.
11. Recent or current diagnoses of post-concussion syndrome, significant head trauma,
substance abuse, addiction, syncope, or epilepsy, that in that the investigator's
opinion would interfere in the assessments.
12. Another significant pain disorder that in the investigator's opinion would interfere
with study-related assessments.
13. Any other information about the subject's medical condition that, in the reasonable
professional judgement of the Investigator, may adversely affect the intended
performance or safety of the study device, or that would confound understanding of the
subjects' response to treatment with the device.
14. Subjects who have been diagnosed with and/or being treated for currently active
chronic neck pain conditions including, but not limited to, failed neck surgery,
discogenic pain, radiculopathy, or whiplash.
15. Psychiatric or cognitive disorders that in the investigator's opinion would interfere
with the conduct of the study
16. Unstable medical conditions which in the investigator's opinion could impede or
preclude successful participation in the study, cause significant risk of serious
adverse events in the study, or limit the subject's ability to complete study related
treatments or assessments.
MEDICATIONS & MIGRAINE TREATMENTS
17. Change in migraine preventive therapies or dosage within the preceding 3 months of
Baseline Visit OR at any point during the study.
18. Head or neck nerve block injections in the past 2 months.
19. Post-COVID-19 patients with new presentations of dysautonomia, cognitive sensory
changes, and imbalance presenting complaints which would limit the subject's ability
to accurately and reliably identify and assess migraine pain, in the investigator's
opinion.
20. Previous use of pressure therapy or surgery in the ear for headache or any other
condition (excluding diagnostic ear insufflation). Subjects enrolling in Group Ib will
have participated in the NC05 study and will be allowed to enter as an exception to
this criterion.
21. Subjects treated with acute migraine medication via IV infusion within two weeks prior
to screening.
22. Subjects with previous absence of therapeutic response to 3 or more acute migraine
neuromodulation devices. (Does not include failure of therapy due to side effects or
intolerance.)
23. Subjects with previous absence of therapeutic response to 3 or more classes of
prescription migraine-specific abortive therapies as judged by the investigator. (Does
not include failure of therapy due to side effects, drug interactions, or
intolerance.)
24. Use of an opioid or barbiturate on more than 4 days per month on average for the 3
months prior to the Baseline Visit.
Individual migraine attacks are excluded from treatment and/or analysis in this study if:
1. Treated >45 days after enrollment into active participation in each study Phase,
applicable for all Groups. Subjects entering into active participation for Phase I
and/or II will have 45 days to treat migraines for that respective Phase. For Phase
II, the 45 days begins after the subject is trained and sent home with an AVPI device
system.
2. Migraine treated more than 10 hours (for Phase I) or 6 hours (for Phase II) after
initial onset of the migraine. Migraines for which the subject cannot reasonably
identify the initial onset.
3. The migraine onset is <24 hours after the complete resolution of a prior migraine
attack.
4. The migraine attack was previously treated with any drug or medical device.
5. The attack is characterized by neck pain that the subject indicates is greater than or
equal to the severity of the headache pain.
6. The subject has developed an ear infection or other new disorder of either ear since
enrollment in the study.
7. The subject has used acute headache or migraine medication or a neuromodulation device
for migraine within previous 24 hours of treatment (for each treatment).
8. The migraine headache intended for treatment during a randomized arm of either Phase
is not at least moderate to severe. Note: Treatment of mild headaches are allowed
during the open-label use arm of either Phase II.
