Trial Outcomes & Findings for A Study Evaluating the Effect of Inhaled PT007(AS MDI) Versus Placebo MDI and Ventolin Evohaler on Lung Function in Adult Participants With Asthma (NCT NCT06644924)

NCT ID: NCT06644924

Last Updated: 2026-08-27

Results Overview

Change from baseline FEV1 measured at each time point for AS MDI and Ventolin Evohaler. Baseline FEV1 is the period specific mean of the available pre-dose values. Area Under the Curve (AUC) 0-6 hours is calculated using the trapezoidal rule and normalized by dividing by the time in hours from dosing to the last measurement included (i.e., \~ 6 hours).

Participant Flow

This study was conducted at 23 sites in the United States, from February 2025 to May 2025. The study was anticipated to run for at least 15 days but not to exceed 52 days.

A total of 164 subjects were screened for the study of which 118 subjects were randomized and treated with one of the 6 treatment sequences. Each sequence comprised all 3 treatments included in this study (i.e., AS MDI 180 μg, Ventolin Evohaler 200 μg, Placebo) in a randomized order. Remaining 46 subjects were not randomized either due to failure to meet randomization criteria, adverse event, not meeting the eligibility criteria at visit 2 or withdrawal from the study.

Timeframe: 0 to 6 hours (Spirometry will be obtained 60 and 30 minutes pre-dose and 5, 15, 30, 45, 60, 120, 180, 240, 300, and 360 minutes post-dose)

Population: Participants who in the Full Analysis Set (FAS), have completed AS MDI and Ventolin Evohaler doses without any Intercurrent Events (ICE) on or before Day 1 of the corresponding AS MDI and Ventolin Evohaler periods, and have AS MDI and Ventolin Evohaler Day 1's pre-dose FEV1 value, at least one FEV1 value post dose 0-3 hours, and at least one FEV1 value post dose 3-6 hours. Participants were analysed according to the actual intervention received.

Change from baseline FEV1 measured at each time point for AS MDI and Ventolin Evohaler. Baseline FEV1 is the period specific mean of the available pre-dose values. Area Under the Curve (AUC) 0-6 hours is calculated using the trapezoidal rule and normalized by dividing by the time in hours from dosing to the last measurement included (i.e., \~ 6 hours).

SECONDARY outcome

Timeframe: 0 to 6 hours (Spirometry will be obtained 60 and 30 minutes pre-dose and 5, 15, 30, 45, 60, 120, 180, 240, 300, and 360 minutes post-dose)

Population: Participants who in the FAS, have completed AS MDI and Ventolin Evohaler doses without any ICEs on or before Day 1 of the corresponding AS MDI and Ventolin Evohaler periods, have AS MDI and Ventolin Evohaler Day 1's pre-dose FEV1 value, and have at least one FEV1 value post dose 0-6 hours. Participants will be analysed according to the actual intervention received.

Peak change from baseline in FEV1 is the difference between the maximum FEV1 value measured during the 6 hour post dose period and the baseline FEV1 for AS MDI and Ventolin Evohaler. Baseline FEV1 is the period specific mean of the available pre-dose values.
