Zavegepant

Pain freedom was defined as pain intensity being none at the specified time point. Participants recorded their headache pain intensity using 4-point numeric rating scale (0= none, 1= mild, 2= moderate, 3= severe).

MBS was selected from nausea, phonophobia or photophobia before dosing by the participants. In this outcome measure, percentage of participants who recorded an MBS (present) before dosing and did not have the MBS (absent) at the time of evaluation (i.e., 2 hours post-dose) were reported.

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.

Minimal pain is defined as 0 or 1 on the 0-4 numerical rating scale.

An AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in participants or clinical investigation participants administered an investigational (medicinal) product that does not necessarily have a causal relationship with this treatment. An SAE was defined as any event that met any of the following criteria at any dose: death; life-threatening; inpatient hospitalization or prolongation of existing hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect in the offspring of a participant who received study drug; other important medical events that may not have resulted in death, be life-threatening, or required hospitalization, based upon appropriate medical judgment, they may have jeopardized the participant and may have required medical or surgical intervention to prevent one of the other serious outcomes.

Clinically significant laboratory abnormalities were defined as Grades 3 to 4 laboratory test results according to numeric laboratory test criteria found in Common Technical Criteria for Adverse Events Version 5.0 (2017) if available; otherwise, according to Division of Acquired Immune Deficiency Syndrome. Table for Grading the Severity of Adult and Pediatric Adverse Events Corrected Version 2.1 (2017) for glucose, low-density lipoprotein (LDL)-cholesterol, uric acid, and urinalysis. Laboratory test groups of clinical interest included hematology, serum chemistry, and urinalysis. Participants must have had a non-missing measurement in to be included for a given parameter. Laboratory results were presented in US units.

Cmax is defined as the maximum observed plasma concentration of zavegepant after administration of a single dose

Tmax is defined as the time to reach maximum observed plasma concentration

AUC (0 - inf) is defined as area under the concentration-time curve from time 0 to infinity.

AUCinf = Area under the breast milk concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf). It is obtained from AUC (0-t) plus AUC (t-inf).

Area under the breast milk concentration time-curve from zero to the last measured concentration (AUClast)

AUC24= Area under the breast milk concentration versus time curve from time zero (pre-dose) to time 24 hours

Maximum plasma concentration (Cmax) was measured.

AUClast, area under the plasma concentration-time profile from time 0 to the time of the last quantifiable concentration (Clast), was measured.

AUCinf, area under the plasma concentration-time curve from time 0 extrapolated to infinite time, was measured.

Tasso device used was Tasso-Plus (for liquid blood sample collection). In Period 1, for the treated participants pharmacokinetic (PK) samples were collected using Tasso-Plus and simultaneously standard venous phlebotomy. Data was to be reported for Tasso-Plus vs. venous phlebotomy concentrations (same participants).

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Vz/F is influenced by the fraction absorbed. Tasso device used was Tasso-Plus (for liquid blood sample collection).
