NCT ID: NCT03872453

Last Updated: 2023-09-25

Results Overview

Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the electronic clinical outcome assessment (eCOA) handheld device. Pain freedom was defined as pain level of none post-dose.

Participant Flow

The study was conducted at 82 sites in the United States.

A total of 2154 participants were enrolled, of which 1673 participants were randomized in a 1:1:1:1 ratio across the 4 treatment groups into the zavegepant (5 mg, 10 mg, or 20 mg) or placebo treatment groups. The randomization was stratified by the use of prophylactic migraine medications (yes or no). 481 participants were not randomized due to lost to follow-up, screen failure, withdrawal by participants, or other reasons.

PRIMARY outcome

Timeframe: 2 hours post-dose

Population: mITT participants included treated participants who were randomized only once, had moderate to severe pain at on-study migraine attack onset, and had non-missing, post-baseline efficacy data.

Pain levels were assessed on a 4-point scale (none, mild, moderate, severe) using the electronic clinical outcome assessment (eCOA) handheld device. Pain freedom was defined as pain level of none post-dose.

PRIMARY outcome

Timeframe: 2 hours post-dose

Population: The mITT participants were analyzed.

MBS was reported as nausea, photophobia, or phonophobia at migraine onset using the eCOA handheld device. Symptom status (absent, present) was assessed post-dose using the eCOA handheld device separately for nausea, photophobia, and phonophobia. Freedom from MBS was defined as MBS reported at on-study migraine attack onset that was absent post-dose.

Timeframe: Through 24 hours post-dose

Population: The mITT participants were analyzed. Participants with rescue medication start date less than or equal to (≤) study drug start date + 1 day and missing rescue medication start time were excluded.

Participants who did not experience relief of their migraine headache at the end of 2 hours after dosing with study medication (and after the 2-hour assessments had been completed on the eCOA handheld device) were permitted to use the following rescue medications: aspirin, ibuprofen, acetaminophen up to 1000 mg/day (this includes Excedrin® Migraine), naproxen (or any other type of nonsteroidal anti-inflammatory drug), antiemetics (for example, metoclopramide or promethazine), or baclofen. The participant's use of rescue medication was recorded by the site on a case report form.
