Last Updated: 2013-10-31

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE2
• Total Enrollment: 35 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2012-01-31
• Study Completion Date: 2013-06-30

Brief Summary

This multi-center, double-blind, placebo-controlled, parallel group trial carbon dioxide in the treatment of moderate to severe migraine. At approximately 8 US sites, approximately 450 patients who meet the eligibility criteria will be randomized to active or placebo in a 1:1 ratio to ensure that 400 patients will treat at least one moderate to severe migraine with the study drug.

Patients will be randomized to one of two treatment groups and be provided with either an active or placebo dispenser.

All patients will administer study drug for 10 seconds to each nostril when experiencing a qualifying headache. Patients will assess their pain and other migraine-related symptoms in a patient diary. If a patient still has pain and/or any other symptoms after the initial dose then the patient may opt to take 3 more doses to treat the headache.

Each patient's participation in the study may last up to 56 days or once the patient treats 4 headaches with the study drug, whichever occurs first.

There will be a total of 2 scheduled clinic visits:

• Visit 1 Screening/Randomization
• Visit 2 End of Study (within 7 days after the patients treats his/her fourth headache or after the end of the 56-day treatment period, whichever occurs first)

Eligibility Criteria

Inclusion Criteria

• Able to read and understand informed consent form and voluntarily consent to participate in this study by signing the IRB-approved informed consent form
• Males and females ages 18 - 65 years
• Established diagnosis of migraine with or without aura per ICHD-II (patients with a diagnosis of only menstrual migraine are not eligible)
• At least a one-year history of migraine symptoms with or without aura
• Age at migraine onset less than 50 years
• History of 2-8 migraine attacks per month during the 3 months prior to randomization
• Females of childbearing potential must commit to using an acceptable method of birth control (e.g., oral birth control pills, intrauterine device (IUD), or a double-barrier method of contraception) through 7 days after last study drug administration. To be considered not of childbearing potential, females must be post-menopausal for at least 2 years or be surgically sterile

Exclusion Criteria

• Have less than 48 hours of freedom from headache between attacks of migraine
• Have 15 or more headache days per month
• Have migraine secondary to traumatic brain injury (TBI)
• Are unable to comply with protocol requirements
• Females who are pregnant or breast-feeding and/or plan to become pregnant or to breast-feed during study participation or within 7 days after last study drug administration
• Have changed their usage of prescription migraine prophylaxis medications within 12 weeks prior to randomization
• Use antipsychotic or antidepressant medications (unless only for migraine prophylaxis) within 12 weeks prior to randomization and for the duration of the study
• Have a history of alcohol or drug abuse within 2 years prior to randomization
• Have a psychiatric disease which may prevent patient compliance or otherwise interfere with the ability of the patient to participate in the study
• Have a medical condition that makes study participation unwise in the opinion of the Investigator (e.g., significant COPD, heart disease, etc.)
• Have a concurrent diagnosis of temporomandibular disorders (TMD) or trigeminal neuralgia requiring treatment
• Clinically significant deviated septum, nasal polyps or other nasal condition that prevents unrestricted breathing through each nostril
• Are going to travel extensively by airplane during the 56-day treatment period (e.g., anticipated travel by airplane more than 25% of the 56-day treatment period, 14 days)
• Have a member of the same household also participating in this study
• Use of any investigational or experimental therapy within 30 days of randomization
• Have participated in another study with nasal CO2

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 65 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
