Clinical Trial Summary

Our protocol, named "KETOMIGRAINE", is based on the prescription of a Ketogenic Diet (KD) to twenty subjects with diagnosis of Chronic Migraine (CM), resistant to oral preventive treatments and non-responders to monoclonal antibodies targeting the CGRP pathway. The trial starts with one month of baseline during which are verified inclusion/exclusion criteria. After that, participants will assume KD for three months, a transitional diet (TD) for other three months. Follows a period of three months of free diet (FD). Neurological and dietician visits are scheduled during the course of the trial.

Description:

The duration of the trial for individual participants is approximately 10 months, divided as follows: 1 month of baseline + 3 months of KD + 3 months of TD+ 3 months of follow-up. The protocol includes 6 neurological evaluations (T0-T5); 11 dietary evaluations, some of which can be remote visits, and will be defined below with the acronym "V" (V1-V11). The planned activities are listed below: - T0 screening: neurological and general physical examination, extended anamnestic evaluation, evaluation of the inclusion / exclusion criteria. Signature of the informed consent for participation in the research study, assignment of an identification code (increasing number starting from 01); headache diary delivery for prospective baseline data collection. - T1 baseline (30 days +/- 3 after T0): assessment of compliance in filling in the headache diary and confirming the diagnosis of chronic migraine; execution of electrocardiogram, pregnancy test (if female patient with childbearing potential) and blood tests (renal, hepatic, lipidic, endocrinological profile); first dietary visit (V1 - anthropometric measurements-BMI, interview on eating habits), nutritional instrumental evaluations (calorimetry and body composition). - T2 Day 1 (Enrollment -7 days +/- 3 after T1): verification of inclusion and exclusion criteria with the results of blood tests; blood sample for collection of PACAP, CGRP and metabolites of kynurenines; compilation of the disability and impact questionnaires - MIDAS and HIT-6; compilation of Migraine Specific Quality of Life Questionnaire (MSQ); dietary assessment (V2): prescription of the KD that the patient will follow for the next 3 months. Subjects overweight will follow a KD with a low-calorie content (low-calorie ketogenic diet); patients with a lower BMI will follow a normo-caloric diet: those represent the two subgroups of the study. Both subtypes of diet (normo and low-calorie) will induce at the same way ketosis; the only difference between the two subgroups is the fact that one will be associated with weight loss and the other not. During the three months of KD, dietician evaluations will be carried out every two weeks, alternating those remotely with those onsite (V3-V7). The dietary visits at the end of the 1st, 2nd and 3rd month of KD will be carried out onsite and the ketone dosage will be carried out using blood sticks. - T3 (3 months from T2 - end of KD and start of transitional diet - TD): evaluation of the headache diary and compilation of the disability and impact scales - MIDAS and HIT-6); repetition of blood tests in order to check dietary tolerance; blood sample for CGRP, PACAP, metabolites of kynurenines (II point); repetition of instrumental measurements (calorimetry and body composition); dietary visit (V8) for the last check of ketonemia and prescription of TD. This type of diet is not ketogenic and is characterized by the gradual introduction of carbohydrates starting from breakfast, it will last for 3 months. Onsite dietary visits (V9-V10) follow on a monthly basis - T4 (3 months after T3 - end of TD and start of free diet - FD): neurological and dietary visit (V 11) at the end of 3 months of TD. The patient will start a free diet, during which he/she can eat what is preferred. - T5 (3 months after T4 - end of study): The last visit is a follow-up, 9 months after T2, its purpose is to evaluate the trend of headache parameters, BMI and biochemical markers studied (III point). During this visit will be filled the following questionnaires: disability and impact questionnaires - MIDAS and HIT-6, Migraine Specific Quality of Life Questionnaire (MSQ), Patient's Global Impression of Change (PGIC).

Other	Effect of KD in the subgroups identified by the type of diet (normal-calorie and low-calorie diet)	The exploratory outcome is to describe the effect of KD in the subgroups identified by the type of diet (normal-calorie and low-calorie diet) in terms of difference of headache days' reduction / per month; the data will be obtained with the analysis of the headache diary filled by the patients.	Through study completion, an average of 10 months
Primary	Change of mean monthly migraine days	The primary endpoint is the change of mean monthly migraine days during the treatment phase compared to the baseline period.

Secondary	Change of average pain intensity	Evaluation of the change of average pain intensity during the study. The average pain intensity will be established by the analysis of the headache diary that the patients are required to fill in for the duration of the study	Through study completion, an average of 10 months
Secondary	change in disability of headache	Evaluation of the change in disability of headache by measuring the variation in points of the questionnaire filled out by the patient named MIDAS (Migraine Disability Assessment). It has 5 items and evaluates the disability caused by headache. A higher score means more disability caused by headache.	Through study completion, an average of 10 months
Secondary	change in impact of headache	Evaluation of the change in impact of headache by measuring the variation in points of the questionnaire filled out by the patient named HIT-6 (Headache Impact Test-6). It has 6 item and evaluates the impact of headache on routinary activities. A higher score means more impact caused by headache.	Through study completion, an average of 10 months
Secondary	change in total pain burden	The purpose is to evaluate the change in total pain burden (number of hours of headache * pain intensity on a scale from 1 to 3) over three months of the KD. These data are established by the analysis of the headache diary hat the patient fills out during all the protocol phases.	Through study completion, an average of 10 months
Secondary	change in quality of life	The change in quality of life is evalueted through the administration of questionnare named: "Migraine Specific Quality of Life Questionnaire" (MSQ) that has 14 items. High score means higher influence of migraine in daily activities.	Through study completion, an average of 10 months
Secondary	Patient's Global Impression of Change	The patients impression of change is evaluated with the administration of a questionnaire: "Patient's Global Impression of Change (PGIC)" that has 1 item with 7 answer options, the seventh option is the best impression of change.	Through study completion, an average of 10 months
Secondary	Evaluation of persistence of KD benefits	The persistence of KD benefits after a period of follow-up is measured by processing the difference in monthly migraine days at the end of follow-up compared to migraine days during KD.	Through study completion, an average of 10 months
Secondary	Mechanism of action of KD	In-depth comprehension of the mechanism of action of KD by evaluating the variation of the plasma levels of neuropeptides involved in the pathophysiology of migraine (Calcitonin Gene Related Peptide CGRP and Peptide Activating Adenylate Cyclase of the Pituitary - PACAP) and of some metabolites of kynurenines (kynurenic and quinolinic acid). These data are obtained by blood samplings.	During the 3 months of Ketogenic diet period
