Criteria
Inclusion Criteria:

- male or female, in otherwise good health, 18 to 65 years of age.

- history of frequent episodic migraine for at least 3 months as defined by 6-14
migraine days per month with or without aura according to the ICHD-3beta or a migraine
treated with an ergot or triptan which resulted in relief.

- onset of migraine before age 50.

- stable history of headache at least 3 months prior to screening.

- if using daily migraine preventive medications for migraine or for other medical
conditions (e.g. propranolol being used for hypertension) and has been on a stable
dose and regimen for at least 2 months prior to beginning the baseline period.

- female, of childbearing potential, and agrees to maintain true abstinence or use (or
have their partner use) one of the listed methods of birth control for the duration of
the study: hormonal contraceptive, intrauterine device (IUD), condoms, diaphragm,
and/or vasectomy. The use of barrier contraceptive (condom or diaphragm) should always
be supplemented with the use of a spermicide. Note: To be considered not of
childbearing potential, subject must be 6 weeks post-surgical bilateral oophorectomy,
hysterectomy, or bilateral tubal ligation, or postmenopausal for at least one year.

Exclusion Criteria:

- unable to understand the study requirements, the informed consent, or complete
headache records as required per protocol.

- pregnant, actively trying to become pregnant, or breast-feeding.

- female of childbearing potential not using adequate contraceptive measures.

- experienced the following migraine variants: basilar migraine, aura without headache,
familial hemiplegic migraine, complicated migraine, ophthalmoplegic migraine and
retinal migraine.

- history of Medication Overuse Headache (Appendix II) in the 3 months prior to study
enrollment or during the baseline phase.

- history of acute migraine treatment greater than 14 days per month in 3 months prior
to screening.

- history of 3 or more failed preventative medications due to lack of efficacy for
prophylactic treatment of migraine after an adequate therapeutic trial.

- received onabotulinumtoxinA injections within 3 months prior to screening and/or will
receive onabotulinumtoxinA injections during the study.

- abused, in the opinion of the Investigator, any of the following drugs, currently or
within the past 1 year: opioids, alcohol, barbiturates, benzodiazepine, cocaine.

- taken, or plans to take: a monoamine oxidase inhibitor (MAOI) including herbal
preparations containing St. John's wort (Hypericum perforatum) within 14 days of Visit
1, concomitant medications and/or foods containing dextromethorphan, quinidine,
quinine, mefloquine, paxil, dicyclomine, digitalis, thioridazine or pimozide
(medications that prolong QT interval) anytime within the 2 weeks prior to screening
through 2 weeks post final study treatment.

- history of hypersensitivity to medications containing dextromethorphan.

- history of hypersensitivity to medications or foods containing quinidine.

- at an increased risk of developing serotonin syndrome, in the opinion of the
investigator.

- history of impaired hepatic or renal function that, in the investigator's opinion,
contraindicates participation in this study.

- unstable neurological condition or a significantly abnormal neurological examination
with focal signs or signs of increased intracranial pressure.

- cardiovascular disease (ischemic heart disease, including angina pectoris, myocardial
infarction, documented silent ischemia, or with Prinzmetal's angina); has symptoms of
ischemic heart disease, ischemic abdominal syndromes, peripheral vascular disease or
Raynaud's Syndrome.

- ECG results outside normal limits (> 470 msec), prolonged QT interval, congenital long
QT syndrome, torsades de pointes, or complete AV block.

- has uncontrolled hypertension (≥ 140/90mmHg in either the systolic or diastolic
measurements in 2 out of 3 BP readings at screening).

- serious illness, or an unstable medical condition, one that could require
hospitalization, or could increase the risk of adverse events, in the opinion of the
investigator.

- any psychiatric disorder with psychotic features and any other psychiatric disorder
not stable or well controlled, that would interfere in their ability to complete study
activities.

- received any investigational agents within 30 days prior to Visit 1.

- plans to participate in another clinical study at any time during this study.
