Clinical Trial Summary

This trial is designed to compare the rate and extent of absorption of four different formulations of zavegepant. 52 healthy male and female volunteers will receive a single dose of each formulation at least 7 days apart over a period of about 7 weeks and the amount of drug in their blood will be assessed over the 24 hour period after each dose.

Description:

This is a Phase 1, single centre, open-label, single dose, 4-period, crossover study designed to compare the pharmacokinetics (PK) of zavegepant from three Test products and a Reference product (treatment D).

52 male and female healthy volunteers will be randomly assigned to one of 4 treatment sequences: ACBD, CDAB, BADC, and DBCA.

In each period, subjects will receive one of the following: Treatment A, B, C, or D on Day 1, followed by 24 hours of PK and safety assessments. On Day 2 subjects will be discharged from the clinical site and instructed to return after at least a 7 day washout time has passed for subsequent periods of treatment.

The study will include a screening visit from Day -28 to Day -2. Eligible subjects will be admitted to the clinical site on Day -1 and will be confined until completion of the assessments on Day 2. There will be a washout period of at least 7 days between doses. Study Exit procedures will be performed after the last assessment on the morning of Day 2 of Period

4. Study Exit procedures will be performed as soon as possible in case of Early Termination.

The total duration of study participation for each subject from Screening through Study Exit is anticipated to be approximately 6.5 weeks.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]	AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).	0, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours post-dose
Primary	Maximum Observed Plasma Concentration (Cmax)	Maximum observed plasma concentration (Cmax) for zavegepant	0, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours post-dose
Primary	Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)	Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)	0, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours post-dose
Secondary	Time to Reach Maximum Observed Plasma Concentration (Tmax)	Time at which Maximum Observed Plasma Concentration (Tmax) is observed	0, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours post-dose
Secondary	Plasma Decay Half-Life (t1/2)	Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.	0, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours post-dose
Secondary	Apparent Oral Clearance (CL/F)	Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modelling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.	0, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours post-dose
Secondary	Apparent Volume of Distribution (Vz/F)	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. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.	0, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours post-dose
