Who may be able to join

  • Ability and willingness to arrive at the investigator's center within 1 hour (±5 min) of migraine pain onset (defined as pain that is consistent with the subject's usual migraine and is of at least moderate severity).
  • Ability and willingness to abstain from taking medications not allowed by the protocol and to meet phone and check-in criteria.
  • Ability and willingness to undergo a comprehensive urine toxicology screen for both licit and illicit drugs.

About this study

Official title: A Phase 2 Safety and Efficacy Study of NPS 1776 for the Acute Treatment of Migraine Headaches

The purpose of this study was to evaluate the effectiveness and safety of a single oral dose of NPS 1776 in the acute treatment of migraine pain and associated symptoms.

Read the detailed description

Migraine, the most common cause of recurrent severe or disabling headache, is diagnosed on the basis of a clinical history of intermittent headache with autonomic, constitutional, and neurologic disturbances.

Many antiepileptic drugs (AEDs) have demonstrated efficacy as acute and/or prophylaxis therapy for migraine, even though the mechanism of action of the various AEDs is poorly understood.

NPS 1776, isovaleramide, is a neutral aliphatic amide. The mechanism by which NPS 1776 exerts its therapeutic actions in nonclinical animal models of disease is unclear. The same is true for many antiepileptics on the market today. NPS 1776 does not appear to bind directly to various CNS receptor centers, although it shows a broad range of anticonvulsant activity in multiple animal models of seizures. This broad profile of anticonvulsant activity is similar to that of valproic acid (VPA), and may also predict NPS 1776 efficacy in the treatment of migraine.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing NPS 1776 (800 mg) and NPS 1776 (400 mg) in people with Migraine Headache, run by Shire at 22 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 6 inclusion and 7 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 3 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 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. Some participants in this study may receive a placebo. 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.

What does the primary outcome measure?

The response rate at 2 hours post-dose such that the percentage of subjects whose migraine pain-intensity score is none [0] or mild [1] at 2 hours post-dose, after a baseline pain intensity of moderate [2] or severe [3] (time frame: 2 hours post-dose). It is what the study was designed to measure, not a finding.

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 3 Jun 2021.
