Outcome Measures

Primary Outcomes (1)

  • Migraine Headache Days Per 4 Week Period Comparing the Last 4 Weeks of Treatment to a 4 Week Pre-treatment Baseline.

    Compare number of migraine headache days pre and post treatment between the ESX and placebo group. Study terminated early-no outcome data available. The single subject assigned to study drug did not actually take it according to subsequent review of ESX drug levels.

    4 weeks, end of treatment and pre-treatment baseline

Study Arms (2)

Arm 1-ethosuximide

EXPERIMENTAL

ethosuximide blinded capsules of 250mg ESX; titration up to 4 capsules qd (expected) or 5 or 6 capsules for efficacy (not to exceed "30mg"/kg/d) vs maximum tolerability

Drug: ethosuximide

Arm 2-placebo comparator

PLACEBO COMPARATOR

placebo same size blinded capsules as the 250mg ESX; similar titration up to 4 capsules qd (expected) or 5 or 6 capsules for efficacy (not to exceed "30mg"/kg/d) vs maximum tolerability

Other: placebo comparator

Interventions

ethosuximide (ESX)

Also known as: zarontin
Arm 1-ethosuximide

placebo

Arm 2-placebo comparator

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Must be a veteran.
  • The number of migraine days per 4-week period is to be 4-14 for a period of 3 months prior to screening for entry into the trial.
  • Migraine must have been occurring for 6 months preceding entry into the trial and age of onset should be before age 60 years.
  • Migraine must be at least moderate severity and interrupt daily activities in some respect at least 3 times per month.

You may not qualify if:

  • Migraine diagnosis:
  • Veterans with headache must have migraine categorized using the International Headache Society (I.H.S.) criteria as illustrated below for the two main types with and without aura.
  • Criteria for migraine without aura (I.H.S. 1.1)
  • \> 5 attacks
  • headache lasting 4-72 hours when untreated or not successfully treated.
  • headache with two of the following characteristics
  • unilateral,
  • pulsating,
  • moderate to severe intensity,
  • aggravation by exertion.
  • one of the following occurs with headache
  • nausea and/or vomiting
  • photophobia and phonophobia
  • Criteria for migraine with aura (I.H.S. 1.2)
  • at least 2 attacks
  • +28 more criteria

Limitations and Caveats

Early termination occurred due to inadequate recruitment of episodic migraineurs in a population meeting too many exclusion criteria; resulting in no subjects available for analysis.
