MRI Study To Identify Functional and Structural Changes That Correlate with Patient Improvement When Imaging the Brain Pre-and-Post Erenumab

Overview

About this study

The purpose of this study is to Identify changes in brain function and structure that correlate with response to erenumab, and to develop models using imaging data to predict which patients will respond to erenumab.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Adults 18‐65 years of age.

    • Headache has at least two of the following four characteristics:
      • Unilateral location;
      • Pulsating quality;
      • Moderate or severe pain intensity;
      • Aggravation or causing avoidance of routine physical activity.
    • During headache at least one of the following:

    • Not better accounted for by another ICHD‐3 diagnosis.
  • Chronic Migraine
    • Headache (migraine‐like or tension‐type like) on at least 15 days per month for longer than 3 months, and fulfilling criteria B and C;
    • Occurring in a patient who has had at least five attacks fulfilling criteria B‐D for “episodic migraine” (above).
    • On at least 8 days per month for longer than 3 months, fulfilling any of the following:
      • Criteria C and D for migraine without aura;
      • Criteria B and C for migraine with aura;
      • Believed by the patient to be a migraine at onset and relieved by a triptan or ergot derivative;
      • Not better accounted for by another ICHD‐3 diagnosis.
  • 10‐25 migraine days per month on average over the 3 months prior to screening, confirmed by run‐in phase prospective data collection.
  • Duration since migraine onset of at least 12 months prior to screening based on medical records and/or patient self‐report.

Exclusion Criteria:

  •  Older than 50 years of age at migraine onset.
  •  History of cluster headache or hemiplegic migraine.
  •  Continuous headache pain (i.e. no pain‐free periods of any duration during the one month before screening).
  •  Opioid‐ or butalbital‐containing analgesics on 6 or more days per month during the 2 months prior to the start of the baseline phase 14.
  •  History of major psychiatric disorder such as schizophrenia and bipolar disorder.
  •  History or evidence of any unstable or clinically significant medical condition, that in the opinion of the investigator, would pose a risk to subject safety or interfere with the study evaluation, procedures, or completion.
  •  No therapeutic response in migraine prevention after an adequate therapeutic trial of 4 or more of the following medication categories:
    • Category 1: divalproex sodium, sodium valproate;
    • Category 2: topiramate;
    • Category 3: beta‐blockers;
    • Category 4: tricyclic antidepressants;
    • Category 5: venlafaxine or desvenlafaxine, duloxetine or milnacipran;
    • Category 6: flunarizine, verapamil;
    • Category 7: lisinopril, candesartan;
    • Category 8: botulinum toxin.
  • No therapeutic response is defined as no reduction in headache frequency, duration, or severity after administration of the medication for at least 6 weeks at the generally accepted therapeutic dose(s) based on the investigator’s assessment. Lack of sustained response to a medication and failure to tolerate a therapeutic dose are not considered to be “no therapeutic response."
  • Concomitant use of 3 or more of the following medications for migraine prevention within 2 months before the start of the baseline phase or throughout the study: divalproex sodium, sodium valproate, topiramate, carbamazepine, gabapentin, beta‐blockers, tricyclic antidepressants, venlafaxine, desvenlafaxine, duloxetine, milnacipran, flunarizine, verapamil, lomerizine, lisinopril, candesartan, clonidine, guanfacine, cyproheptadine, methysergide, pizotifen, butterbur, feverfew, magnesium (at least 600 mg per day), riboflavin (at least 100 mg per day).
  • Use of up to two medications is permitted as long as the dose has been stable for at least 2 months before the start of the run‐in phase and during the study.
  • Botulinum toxin (in the head and/or neck region) within 4 months before the start of the baseline phase and throughout the study.
  • Ergotamine derivatives, steroids, and triptans used for migraine prophylaxis within 2 months before the start of the baseline phase and throughout the study.
  • Procedures (e.g. nerve blocks) used for migraine prophylaxis within 2 months before the start of the baseline phase and throughout the study 15.
  • History of myocardial infarction, stroke, transient ischemic attack, unstable angina, coronary artery bypass surgery, or other revascularization procedures within 12 months prior to screening.
  • Contraindications to MRI including, but not limited to:
    • Metal implants;
    • Aneurysm clips;
    • Severe claustrophobia;
    • Implanted electronic devices;
    • Insulin or infusion pump;
    • Cochlear/otologic/ear implant;
    • Non‐removable prosthesis;
    • Implanted shunts/catheters;
    • Certain intrauterine devices;
    • Tattooed makeup;
    • Body piercings that cannot be removed;
    • Metal fragments;
    • Wire sutures or metal staples.
  • Factors that reduce MR image quality and interpretability:
    • Dental braces or other non‐removable devices (e.g., retainers);
    • Prior brain surgery;
    • Known brain MRI abnormality that in the investigator’s opinion will significantly impact MRI data.
  • Sensory disorders that in the investigator’s opinion might affect perception of cutaneous thermal stimuli (e.g., peripheral neuropathy).
  • Pregnancy.
  • Lactation.
  • Not willing to use a reliable form of contraception (for women of childbearing potential) through 16 weeks after the last dose of erenumab. Acceptable methods of birth control include not having intercourse, hormonal birth control methods, intrauterine devices, surgical contraceptive methods, or two barrier methods (each partner must use a barrier method) with spermicide. A reliable form of contraception must be started prior to or at the time of starting the run‐in phase. Not being of childbearing potential is defined as any woman who:
    • Is post‐menopausal by history, defined as:
      • At least 55 years of age with cessation of menses for 12 or more months; OR
      • Younger than 55 years of age but no spontaneous menses for at least 2 years; OR
      • Younger than 55 years of age and spontaneous menses within the past 1 year, but currently amenorrheic (e.g. spontaneous or secondary to hysterectomy), AND with postmenopausal gonadotropin levels (luteinizing hormone and 16 follicle‐stimulating hormone levels at least 40 IU/L) or postmenopausal estradiol level (less than 5 ng/dL) or according to the definition of “postmenopausal range” for the laboratory involved.;OR
      • Underwent bilateral oophorectomy; OR
      • Underwent hysterectomy; OR
      • Underwent bilateral salpingectomy.
  • Currently receiving treatment in another drug study or an investigational device study, or less than 90 days prior to screening since ending treatment on another investigational device or drug study(‐ies).
  • Has received CGRP monoclonal antibody within 4 months of the start of the run‐in phase.
  • Active chronic pain condition that in the investigator’s opinion is unrelated to migraine (e.g., chronic pelvic pain).
  • Acute pain condition that in the investigator’s opinion is unrelated to migraine (e.g., postsurgical pain).
  • Unable to provide informed consent.
  • Less than 80% compliance with providing headache diary data during the run‐in phase (i.e., provides data on less than 80% of days).
