Trial Outcomes & Findings for A Study to Compare Zavegepant Concentration Using Samples Collected From the Vein Versus Patient-Centric Microsampling (NCT NCT05948085)

NCT ID: NCT05948085

Last Updated: 2026-01-29

Results Overview

Tasso device used was Tasso-Plus (for liquid blood sample collection). In Period 1, for the treated participants 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).

Measure
Zavegepant
On Day 1 of Period 1, all participants received Zavegepant 10 milligrams (mg) via intranasal (IN) route (single use unidose nasal spray). Period 1 was followed by Period 2. On Day 1 of Period 2, all participants received a butterscotch candy and 5 minutes later received Zavegepant 10 mg single use unidose nasal spray. Participants were followed up 28-35 days after the second (last) dose.

PRIMARY outcome

Timeframe: 30 minutes post-dose on Day 1 of Period 1

Population: PK concentration analysis set: all enrolled participants who received 1 single IN dose of Zavegepant and provided at least 1 evaluable plasma concentration. Here, ''Overall Number of Participants Analyzed'' signifies participants evaluable for this outcome measure.

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.

SECONDARY outcome

Timeframe: From Day 1 of dosing up to 35 days post last dose of study drug (up to 37 days)

Population: Safety analysis set included all participants who received at least 1 dose of study intervention. Participants were analyzed according to the product they actually received.

An adverse event (AE) was any untoward medical occurrence in a participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. TEAEs were defined as events from Day 1 of dosing up to 35 days post last dose of study drug that were absent before treatment or that worsened relative to pre-treatment state.
