About this study

Official title: An Open Post-marketing Clinical Follow-up Investigation to Follow Long-term Performance and Safety of Intranasal Kinetic Oscillation in Subjects With Chronic Migraine

An non controlled, long term, multi center investigation

Read the detailed description

Subjects who provided written informed consent and are eligible for the study will be asked to complete a daily diary for 4 weeks during the screening period. In the diary the subjects will record headache and migraine days, any changes in their health, and concomitant medications they may be using. The data collected in the diary during this screening period will be used as Baseline for the performance assessments.

A non-controlled, long term, multi-center investigation for symptom improvement in subjects suffering headache and migraine attacks.

During the run-in (baseline) period and through the whole study the subjects will continue using their existing prescribed or over the counter (OTC) treatments.

Following the run-in period (4 weeks) the subjects will be treated six times within a period that is approximately 6 weeks. The first treatment will be given the first day after the run-in period.

During 12-month follow-up period (from the time of the first treatment), subjects will be treated when needed but a maximum of 14 treatments.

Being tested
KOS (Intranasal kinetic oscillation stimulation)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • KOS (Intranasal kinetic oscillation stimulation)Device

    Treatment is 10 minutes in each nasal cavity. Totally 2 x 10 minutes per treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To evaluate the efficacy of intranasal kinetic oscillation stimulation using the Chordate System S220 on monthly headache days with moderate to severe intensity after approx 6 weeks of treatment.

    Change in proportion of days with headache with moderate to severe intensity compared to the four week period starting the day after the third treatment Headache days are collected in electronic diary (eDiary)

    Measured: Baseline to 6 weeks

Secondary outcomes (6)
  1. To evaluate the efficacy of treatment with KOS on monthly migraine days (regardless of intensity) Description: Migraine days are collected in an eDiary.

    Migraine days is collected in an eDiary.

    Measured: Baseline to 12 month

  2. To evaluate the incidence and severity of adverse events (AEs) and adverse device effects (ADEs) following treatment with the Chordate System S220.

    All adverse events (AEs) and adverse device effects (ADEs) incidence and severity following treatment with KOS

    Measured: Baseline to 12 month

  3. Number of patients who are responders

    Responders are classified as responder (less migraine/headache days) or non-responder (same or worsening of migraine/headache days).

    A responder is a patient who has decrease of headache/migraine days whilst a non responder had no or the same number of headache/migraine days

    Measured: Baseline to 12 month

  4. Number of patients who decrease use of abortive medication

    Intake of abortive medications are registered in eDiary and will be calculated on patient level

    Measured: Baseline to 12 month

  5. Mean change in Headache Impact Test (HIT-6)

    HIT-6 consist of 6 questions HIT-6 with scores from 6 to 13 where 13 is worst case per question so lower score is better outcome than high scores.

    Measured: Baseline to 12 month

  6. Mean change in Subject global severity

    Patient Global severity is a scale with four (4) scores, where normal (0) is the lowest and show no problems whilst severe (3) is the worst score 0. Normal

    1. Mild
    2. Moderate
    3. Severe

    Measured: Baseline to 12 month

Individual data sharing
No: Due to uncertainties in EU data protection legislation individual de-identified participant data are not shared. The main uncertainty is the concept of what "de-identified" means. It appears not to mean that the data set of a person is simply separated from the person's name. What additional operations have to be done appears to depend on technological capabilities to re-identify the persons associated with the data set. A common perception is that the technological capabilities for re-identification are permanently increasing. This could have the effect that public data sets that are regarded as de-identified now might become re-identifiable data sets in the future. Once this happens, the sponsor is no longer able to make the publication of the data sets un-happen. This could result in punishment by EU data protection authorities. The sponsor wants to avoid this.

Questions about this trial

What is this clinical trial studying?

A study testing KOS (Intranasal kinetic oscillation stimulation) in people with Chronic Migraine, run by Chordate Medical at 12 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

Where is the study taking place?

The record lists 12 sites in Germany, Italy, United Kingdom, Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Difficulties recruiting patients in combination with good results in data analysis.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To evaluate the efficacy of intranasal kinetic oscillation stimulation using the Chordate System S220 on monthly headache days with moderate to severe intensity after approx 6 weeks of treatment. (time frame: Baseline to 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Sep 2025.
