Brief summary

The purpose of this pilot study is to evaluate the performance of the Chordate System, in terms of the prophylactic effect and tolerability of treatment in patients diagnosed with migraine.

Detailed description

This was a prospective, interventional, randomized, placebo-controlled, double-blind, multi-center clinical investigation of a medical device system. A pilot study in which patients with frequent migraine attacks received intranasal KOS or placebo using the Chordate System S200 on two occasions.

Interventions

DEVICEChordate System S200 + CT100 (active treatment)

Chordate S200 + CT100 (active treatment) gives Kinetic Oscillation Stimulation for 15 minutes to each nostril and by that giving an effect on the autonomic nervous system (ANS).

DEVICEChordate System S200 + CT100 (placebo treatment)

Chordate S200 + CT100 (placebo) is used in the same way as Active treatment, but no Kinetic Oscillation Stimulation is given. Catheter is not inflated and no vibration is given.

Masking description

A placebo module, with one input and 6 outputs, was added to the Chordate S200 system. Some outputs delivered active treatment and others placebo. The operator received a coded envelope and according to that, either active treatment or placebo was selected. The operator did not know which outputs delivered treatment and which did not.

MeasureTime frameDescription
Change From Baseline in Number of Migraine Days Per Four Weeks During the Three Months Post Treatment Investigation DurationFrom baseline (28 days pre-treatment) to visit 4 (day 98, ± 7 days)A diary was used where patients added information each day on experienced migraine (yes/no). Baseline was defined as any migraine days from Day -29 until Day -1, i.e. the day before first treatment (Day 1). If full time period for baseline or the post treatment period was not documented, number of migraine days was recalculated with the formula: Number of migraine days = (Number of migraine days x 28) / Number of days observed If data was missing for any patient for more than 14 days during any period of interest, that patient was excluded from analysis. The change from baseline in number of migraine days was calculated as follows: Change = number of migraine days per four weeks for the 3 months post treatment period - number of migraine days per four weeks of the baseline period As the difference between the post treatment period and baseline is presented, negative numbers indicate a post treatment decrease in number of migraine days.

The median migraine duration in hours per day was determined for each patient, for each post treatment time period. Baseline for each patient was defined as the median number of migraine hours/day from Day -29 until Day -1, i.e. the day before the first treatment (Day 1). The change in median migraine hours/day from baseline, for each defined post treatment time period, was then determined and the mean change is presented. As the differences between applicable post treatment period and baseline is presented, negative numbers indicate a post treatment decrease in number of migraine hours/day.

The change from baseline in number of migraine days was calculated as follows: Change = number of migraine days per four weeks for applicable post treatment period - number of migraine days per four weeks of the baseline period As the difference between applicable post treatment period and baseline is presented, negative numbers indicate a post treatment decrease in number of migraine days.

Mean Change From Baseline in Median Migraine Duration (Hours/Day) During the 1st, 2nd and 3rd Month, the Final 4 Weeks and the Complete Three Month Post Treatment Investigation Duration

A diary was used where patients added information each day on the number of hours with migraine. The median migraine duration in hours per day was determined for each patient, for each post treatment time period. Baseline for each patient was defined as the median number of migraine hours/day from Day -29 until Day -1, i.e. the day before the first treatment (Day 1). The change in median migraine hours/day from baseline, for each defined post treatment time period, was then determined and the mean change is presented. As the differences between applicable post treatment period and baseline is presented, negative numbers indicate a post treatment decrease in number of migraine hours/day.

Time frame: From baseline (28 days pre-treatment) to visit 4 (day 98, ± 7 days)

Population: 44 patients were allocated to active treatment and 43 to placebo. Out of these 40 patients completed the active treatment and 38 patients completed placebo treatment (see participant flow). Only patients who completed treatment were included in analysis. If a patient had missing data for more than 14 days for any of the periods of interest, that period was excluded from the statistical analysis of the applicable endpoint.

Number of Participants With a Change in Disease-specific Quality of Life From Baseline to End of the Three Month Investigation Duration

Number of Participants with a Change in Disease-specific Quality of Life, as measured by EQ-5D-3L, from Baseline (day 0, visit 2 before first treatment) to End of the Three Month Investigation Duration. EQ-5D-3L uses 5 categorical dimensions - motility, self-care, usual activities, pain/discomfort and anxiety/depression, each classified as improved, no change or worsened.

Time frame: From baseline (day 0, visit 2) to visit 4 (day 98, ± 7 days)

Population: 44 patients were allocated to active treatment and 43 to placebo. Out of these 40 patients completed the active treatment and 38 patients completed placebo treatment (see participant flow). Only patients who completed treatment were included in analysis. If a patient had missing data for more than 14 days for any of the periods of interest, that period was excluded from the statistical analysis of the applicable endpoint.

Patient's Satisfaction as Measured on Clinical Global Impression Scales (CGI)

Patient satisfaction, evaluated by a clinician, was measured using 8-point clinical global impression (CGI) scores on an improvement scale (CGI-I: compared to condition at baseline, how much has changed: 0 = Not assessed, 1 = Very much improved, 2 = Much improved, 3 = Minimally improved, 4 = No change, 5 = Minimally worse, 6 = Much worse, 7 = Very much worse).

Time frame: At visit 4 day 98, ± 7 days

Population: 44 patients were allocated to active treatment and 43 to placebo. Out of these 40 patients completed the active treatment and 38 patients completed placebo treatment (see participant flow). Only patients who completed treatment were included in analysis.

Responder Rate

Responder defined as a patient with 50% or greater decrease in the number of migraine days per four weeks, for the 1st, 2nd and 3rd month post treatment vs baseline

Time frame: From baseline (28 days pre-treatment) to visit 4 (day 98, ± 7 days)

Population: 44 patients were allocated to active treatment and 43 to placebo. Out of these 40 patients completed the active treatment and 38 patients completed placebo treatment (see participant flow). Only patients who completed treatment were included in analysis. If a patient had missing data for more than 14 days for any of the periods of interest, that period was excluded from the statistical analysis of the applicable endpoint.
