Clinical Trial Summary

The aim is to assess the efficacy of adding on a Mindfulness-based therapy to pharmacological prophylaxis (experimental group: pharmacological prophylaxis + Mindfulness) against pharmacological prophylaxis only (control group) on the reduction of monthly headaches frequency (primary endpoint), symptomatic medications intake, inflammatory pattern, depression, anxiety, cutaneous allodynia, improving disability and quality of life (secondary endpoints). Moreover, other aims are to assess whether adding on Mindfulness-based therapy is also associated to a superior improvement of neuroimaging pattern among patients prescribed neuromodulators or antidepressants and to assess the cost-efficacy of adding on a Mindfulness-based therapy to pharmacological prophylaxis. Mindfulness will be provided in small groups (5-7 patients each) by specifically trained therapists. The treatment consists in six 45 minutes weekly sessions in which one will work on meditation, acceptance and awareness. The program of control group will consist in education of patients, followed by pharmacological prophylaxis. Prophylaxis is prescribed based on patients' profile, such as previous failures, contraindications and so on by a neurologist with expertise in headache treatments. We expect that adding-on Mindfulness will determine a wider reduction of headaches frequency and improvement of secondary endpoints, and that disease cost reduction will support the cost-efficacy of Mindfulness. The study will be a Phase III; randomized, Open-Label; Monocentric study. Patients will be enrolled to detect a 20% difference between the two groups on the primary outcome (50% or more of headache reduction by 12 months). For each medication type and research arm 20 patients will be selected: thus 80 patients will be enrolled for neuroradiological investigation.

Description:

Background and significance. Chronic migraine (CM) is a negative evolution of migraine characterized by frequent headache attacks (>45 days/three months) with a 1-year prevalence of 3.1%. Comorbidities, lifestyle and excessive intakes of symptomatic medications (medication overuse-MO) play a role in progression into CM; altered inflammatory state (WBC, peripheral blood lymphocyte subsets CD3, CD4, CD8, CD19) and dysfunctions in the mesocorticolimbic dopamine circuit were found in CMMO patients. To prevent CM-MO relapse, withdrawal of overused drugs and complementing pharmacological prophylaxis with behavioral treatments is indicated [5]. Withdrawal from MO and medical prophylaxis determine a 30-40% reduction in headaches frequency by 12 months, and 40-50% of patients show a reduction >=50%. Conversely, 30% of them relapse into CM-MO by 12 months: the main drivers include overuse of analgesic compared to triptans and being on medical therapy alone compared to adjuvant psychological techniques. Research demonstrated the utility of relaxation training, stress management, cognitive-behavioral therapy in migraine disorder. Parallel to this, mindfulness showed considerable promise particularly on headache-related disability, affective distress: however, to date evidence of its efficacy is limited by small trials, short follow-up periods, inadequate power and poor consideration of primary outcomes for CM research, i.e. reduction of headaches frequency. Our main hypothesis is that mindfulness might provide additional benefit, when added to medical prophylaxis alone, on both primary (i.e. an increased number of patients showing a reduction of headaches frequency >=50%) and secondary outcomes: reduction in the consumption of symptomatic medications (i.e. analgesics, triptans, opioids, ergot-derivate), reduction of disability, depression, anxiety and cutaneous allodynia, improvement in quality of life; reduction of costs, connected to both lower direct medical costs (e.g. drugs consumption and attendance to ER) and indirect costs (i.e. reduction in lost workdays and improved workplace efficiency); reduction in concentration of the markers of inflammatory pattern; reversible neuroadaptations highlighted by functional connectivity in regions of dopaminergic circuit.

The study will be a Phase III; randomized, Open-Label; Monocentric study. Patients will be enrolled to detect a 20% difference between the two groups on the primary outcome (50% or more of headache reduction by 12 months). We set alpha 0.05 and power 80%, and foresee that up to 12% of patients might be lost at follow-up: therefore, we determined that 170 patients should be randomized 1:1 to the two groups. Patients will be excluded if they: have psychiatric comorbidities of psychotic area; pregnancy; comorbidity with secondary headaches (e.g. idiopathic intracranial hypertension); were submitted to withdrawal from MO at least twice in the previous two years; attended any mindfulness-based therapy. For each medication type and research arm 20 patients will be selected: thus 80 patients will be enrolled for neuroradiological investigation. The treatment consists in six 45 minutes weekly sessions. The main focus of the six session will be the following: 1) introduction and meaning; 2) Focus on breath; 3) posture and body awareness; 4) meditation of sounds; 5) Guided imagery; 6) acceptance and awareness.

Our project is highly innovative as it will be the first time in which a new emerging treatment like Mindfulness is tested for its efficacy and cost-efficacy when added to standard pharmacological prophylaxis. If our hypothesis will be confirmed, then we will positively impact on: a) clinicians, that will have confirmation of another valid adjuvant treatment option; b) national health system, that will cut down the relevant costs of medication intake and indirect costs associated to reduced productivity; c) patients, that will enhance their ability to cope with headaches and improve their overall health, quality of life, work-ability and reduce their disability. Moreover, our study will address the possible impact of Mindfulness as an add-on to pharmacological prophylaxis not only on clinical data, such as headaches frequency and symptomatic medications intake, but also on biomarkers of inflammatory and functional neuroimaging patterns.

Intervention

Behavioral:
• Mindfulness
The experimental group will receive education, will be prescribed prophylaxis and will attend Mindfulness-based therapy sessions. The MINDFULNESS therapy consists in 6 weekly sessions, 45 minutes each. The main focus of the six mindfulness session will be the following: 1) introduction and meaning; 2) Focus on breath; 3) posture and body awareness; 4) meditation of sounds; 5) Guided imagery; 6) acceptance and awareness. During training, patients will be invited to close their eyes, assume a relaxed position, focus on their breathing and on the present to enhance awareness of current mind and body sensations. Patients will be trained in small groups (5-7 patients each) and guided by a specifically trained therapist. They will be educated to practice at home according to the instructions given by the therapist during the sessions.

Drug:
• Prophylactic
Control group will receive education on the use of pharmacological compounds for acute treatment and on healthy lifestyle habits (e.g. adequate sleep/wake pattern, eating and hydration, physical activity, avoidance of triggers) and will be prescribed prophylactic medications. The preventive compound will be chosen on the basis of clinical profile among the following categories: neuromodulators (e.g. topiramate or valproate), antidepressant (e.g. tricyclics or SSRIs) or others, e.g. beta-blockers.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Headache frequency reduction	Percentage of patients achieving 50% or more of headache frequency reduction at 12-months compared to baseline assessed with headache diary.	12 months
Secondary	Neuroimaging pattern	Change in neuroimaging pattern among patients prescribed neuromodulators (e.g. valproate or topiramate) or antidepressants (e.g. tricyclics or SSRIs) assessed with functional magnetic imaging (rs-fMRI).	12 months
Secondary	Cost-efficacy	Differences in cost-efficacy of adding on a Mindfulness-based therapy to pharmacological prophylaxis assessed with self-reports in which patients specify lost workdays and days worked with reduced efficacy (indirect costs), and drug intake by type and medical procedures (direct costs).	3, 6, 12 months
Secondary	Health and disability	Change in health and disability scores, assessed with the WHO Disability Assessment Schedule 2.1 (WHODAS 2.0) WHODAS 2.0 covers 6 Domains of Functioning, including: Cognition, Mobility, Self-care, Getting along , Life activities, Participation. Each item has 5 answers with their scores from "none" to "extreme". The summary score ranges from 0-100 (0 = no disability; 100 = full disability).	3, 6, 12 months
Secondary	Disability	Change in disability scores, assessed with Headache Impact Test-6 (HIT-6) The HIT-6 consists of six items: pain, social functioning, role functioning, vitality, cognitive functioning, and psychological distress. The patient answers each of the six related questions using one of the following five responses: "never", "rarely", "sometimes", "very often", or "always". Each answer is associated with a different score: "never" 6 points, "rarely" 8 points, "sometimes" 10 points, "very often" 10 points," always" 13 points. These responses are summed to produce a total HIT-6 score that ranges from 36 to 78, where a higher score indicates a greater impact of headache on the daily life of the respondent.	3, 6, 12 months
Secondary	Change in Quality of life	Change in quality of life, assessed with the Migraine-Specific Quality of Life Questionnaire 2.1 (MSQ 2.1) The MSQ is a 14-item instrument that measures the impact of migraine across three essential aspects of a patient's health-related quality of life over the past 4 weeks: role function-restrictive (7 items assessing how migraines limit one's daily social and work-related activities) , role function-preventive (4 items assessing how migraines prevent these activities), and emotional function (3 items assessing the emotions associated with migraines). Participant respond to items using a 6-point scale: "none of the time," "a little bit of the time," "some of the time," "a good bit of the time," "most of the time," and "all of the time," which are assigned scores of 1 to 6, respectively. Raw dimension scores are computed as a sum of item responses and rescaled from a 0 to 100 scale such that higher scores indicate better quality of life.	3, 6, 12 months
Secondary	Depression	Change in depression scores, assessed with beck depression inventory-II and (BDI-II) The BDI-II is a questionnaire composed of 21 items that refer to a wide range of somatic affective and cognitive symptoms related to depression. For each item the subject must respond by choosing between 4 alternatives corresponding to different levels of severity. Each alternative is associated with a score ranging from 0 to 3. Total score is obtained by adding the scores of each item. The total score ranges from 0 to 63. Higher scores indicate more severe depressive symptoms: 0-13: minimal depression, 14-19: mild depression, 20-28: moderate depression, 29-63: severe depression.	3, 6, 12 months
Secondary	Anxiety	Change in anxiety scores, assessed with state-trait anxiety inventory forme Y (STAY-Y) STAI comprises separate self-report scales for measuring state and trait anxiety.; STAI comprises separate self-report scales for measuring state and trait anxiety. The STAI Form Y-1 consists of 20 statements that evaluate how respondents feel "right now, at this moment". The STAI Form Y-2 consists of 20 statements that assess how people generally feel. Each STAI item is given a weighted score of 1 to 4. Scores for both can vary from a min of 20 to a max of 80.	3, 6 and 12 months
Secondary	Allodynia	Change in allodynia, assessed with the Allodynia Symptom Checklist (ASC)	3, 6 and 12 months
Secondary	Inflammatory pattern	Change in Biomarkers of inflammatory pattern (WBC, lymphocyte subsets CD3, CD4, CD8, CD19, Treg cells, IL6) The units of measurement, WBC and lymphocyte subpopulations (CD3, CD4, CD8, CD19, Treg), are expressed in number / ml, IL-6 in pg / mL. The different parameters are not aggregated for a composite measure.	6 and 12 months
Secondary	Medications consumption	Change in medications consumption assessed with headache diary	3, 6 and 12 months
