Study Description

Brief Summary:

Suffering from dizzy spells and migraine headaches?

Vestibular Migraine (VM), a newly recognized type of migraine that causes bouts of dizziness.

University of California, Los Angeles (UCLA) and The Mayo Clinic is seeking people with VM to participate in a research study. The purpose of this study is to look at the natural history of VM and learn more about common symptoms. Investigators also want to learn the effects, both positive and negative, of the commonly used migraine drug, rizatriptan, when it is used for spells of dizziness in people with VM.

Patients may be eligible to participate if:

• Patients are between the ages of 18 & 65
• Patients have a history of vestibular migraine
• Patients are able to maintain a vestibular symptom diary

The study includes 3 visits with compensation. All participants must complete questionnaires on dizziness, headache symptoms, general health and well-being, mental health, and a questionnaire on patient's satisfaction with study medication.

Condition or disease	Intervention/treatment	Phase
Vestibular Migraine; Migrainous Vertigo	Drug: Rizatriptan; Drug: Placebo	Phase 2; Phase 3

Detailed Description:

The primary Specific Aim is to conduct the first successful controlled study of a treatment for Vestibular Migraine. The investigators hypothesize that rizatriptan will be superior to a look alike inactive capsule for:

1a. Reducing the severity and duration of vertigo attacks in patients with Vestibular Migraine,

1b. Reducing the severity of symptoms commonly associated with vertigo attacks in patients with Vestibular Migraine (e.g., nausea, vomiting, motion sensitivity, gait disturbance, headache, light and sound sensitivity), and

1c. Improving treatment satisfaction and health-related quality of life in patients with Vestibular Migraine, and that

1d. Rizatriptan will be well tolerated by patients with Vestibular Migraine.

• Primary Purpose: Treatment
• Official Title: A Phase II/III Trial on Rizatriptan for Vestibular Migraine

Arms and Interventions

Arm	Intervention/treatment
Placebo Comparator: Placebo; During the Treatment Phase, three placebo capsules will be administered to each subject. One capsule will be taken during one acute episode, until three episodes are treated with the study drug.	Drug: Placebo; During the study either placebo or Rizatriptan will be given to subjects to take during the treatment phase of the study.; Other Name: Sugar Pill
Experimental: Rizatriptan; During the Treatment Phase, three Rizatriptan capsules will be administered to each subject. One capsule will be taken during one acute episode, until three episodes are treated with the study drug.	Drug: Rizatriptan; During the study either placebo or Rizatriptan will be given to subjects to take during the treatment phase of this study.; Other Name: Maxalt

Outcome Measures

Primary Outcome Measures :

1. Proportion of treated vestibular migraine (VM) attacks in which subjects experience a reduction in severity rating [ Time Frame: Baseline, 1 hour after taking study medication ]
   After each attack subjects will complete an Acute Episode Rating form. Severity will be graded on a scale of 0 to 3, with 0 indicating " symptoms absent" and 3 indicating "severe symptoms"

Secondary Outcome Measures :

1. Treatment Satisfaction at 48 hours [ Time Frame: 48 hours after each attack treated with study medication ]
   Subjects will complete the Treatment Satisfaction Questionnaire for Medication (TSMQ) 48 hours after each attack treated with study medication.

Eligibility Criteria

• Ages Eligible for Study: 18 Years to 65 Years (Adult, Older Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No
