About this study

Official title: A Double-Blind, Randomized, Multicenter, Parallel Dose Study to Evaluate the Safety and Efficacy of Zonisamide 150 mg and 300 mg Per Day and Placebo in Subjects With Migraine Headache

The purpose of this study is to determine if zonisamide is effective as a preventative medication for individuals with migraine headache.

Read the detailed description

The pharmacologic treatment of migraine may be acute (abortive, symptomatic) or preventive (prophylactic). Preventive medication is usually given daily for months or years; however, treatment may also be given in an intermittent regimen. Most migraine prophylactic medications were designed to treat other disorders, and they can be divided into three groups:

  1. Serotonergic or monoaminergic agents such as methysergide, which have demonstrated high degrees of effectiveness;
  2. Non-serotonergic drugs such as beta-blockers, tricyclic antidepressants, valproate; and
  3. Drugs with lesser demonstrated effectiveness, such as selective serotonin reuptake inhibitors, calcium channel antagonists, and non-steroidal anti-inflammatory drugs.

The choice of treatment must be individualized, and is influenced by contraindications, potential side effects, the need to treat associated symptoms like tension-type headache and insomnia, and drug cost.

Anticonvulsants, such as valproate, have shown significant degrees of efficacy in migraine prophylaxis when used in low doses. Considering the differences in proposed mechanisms of action of these agents, it is likely that a novel anticonvulsant such as zonisamide may also be an effective prophylactic treatment for migraine.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing zonisamide in people with Migraine Headache, run by Elan Pharmaceuticals at 13 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Dec 2015.
