Eletriptan vs Sumatriptan: A Double-blind, Placebo-controlled, Multiple Migraine Attack Study

January 26, 2021 updated by: Pfizer's Upjohn has merged with Mylan to form Viatris Inc.

A Multicentre, Double Blind, Double Dummy, Parallel Group, Placebo Controlled, Study of Two Dose Levels of Oral Eletriptan and Two Dose Levels Oral Sumatriptan Given for the Acute Treatment of Migraine(With and Without Aura).

A previously published, placebo-controlled, head-to-head comparator study found eletriptan to have superior efficacy to oral sumatriptan 100 mg in treating a single acute migraine attack. The goal of the current study was to extend the findings of that study by examining the efficacy of eletriptan compared with both 50- and 100-mg doses of sumatriptan; and to evaluate the comparative efficacy of eletriptan and sumatriptan across additional important clinical outcomes. In particular, early response (at 1 hour), sustained response (without need for additional treatment) at 24 hours, and consistency of response across multiple attacks were examined.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
1008

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Eligible patients were men and women with a minimum age limit of 18 years of age (in Canada there was also an age limit of 65 years) who were expected to have at least one attack of migraine with or without aura, as defined by the International Headache Society (IHS) criteria,15 every 6 weeks.
  • Patients had to be capable of taking study medication as outpatients and recording the effects.

Exclusion Criteria:

  • Pregnant or breast-feeding women and those not using adequate contraception were excluded from the trial.
  • Patients with frequent nonmigrainous headache, atypical migraine that had not previously responded to therapy, migraine with prolonged aura, familial hemiplegic migraine, basilar migraine, or migrainous infarction were excluded from the trial.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Headache response at 1 hour after treatment of the first attack.
Time Frame: 1 hour
Headache response was defined as improvement from a severe or moderate headache at baseline to either a mild or absent headache post-dose.
1 hour

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Headache severity
Time Frame: .5, 1, 2, 4 and 24 hours
.5, 1, 2, 4 and 24 hours
Pain-free response
Time Frame: .5, 1, 2, 4 and 24 hours
.5, 1, 2, 4 and 24 hours
Functional response
Time Frame: .5, 1, 2, 4 and 24 hours
.5, 1, 2, 4 and 24 hours
Presence or absence of nausea, photophobia, and phonophobia
Time Frame: .5, 1, 2, 4 and 24 hours
.5, 1, 2, 4 and 24 hours

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
