Trial Outcomes & Findings for Peak Inspiratory Flow and Dry Powder Inhaler Performance in COPD (NCT NCT04606394)

NCT ID: NCT04606394

Last Updated: 2023-05-08

Results Overview

Outcome = the number of subject test days (2 test days per subject) meeting responder criteria defined as: DPI Responder - a positive (\>50 ml) peak FEV1 response 2 hours after Trelegy Ellipta® DPI with a negative (\<50mL) peak FEV1 response 30 minutes after Ventolin® pMDI (2.5 hours post Trelegy) DPI Partial Responder a positive (\>50 ml) peak FEV1 response 2 hours after Trelegy® Ellipta DPI with a positive (\>50 ml) peak FEV1 response 30 minutes after Ventolin® pMDI (2.5 hours post Trelegy) DPI Failure - a negative (\<50mL) peak FEV1 response 2 hours after Trelegy Ellipta® DPI with a positive (\>50 ml) peak FEV1 response 30 minutes after Ventolin® pMDI (2.5 hours post Trelegy) Irreversible - a negative (\<50mL) peak FEV1 response 2 hours after Trelegy Ellipta® DPI with a negative (\<50mL) peak FEV1 response 30 minutes after Ventolin® pMDI (2.5 hours post Trelegy)

Participant Flow

Severe/very severe COPD patients in stable condition stratified to insure that at least 12 of 30 subjects had a suboptimal peak inspiratory flow (PIF \<60L/min)

Enrollment, run-in on current maintenance therapy followed by testing, conversion of maintenance therapy to Trelegy Ellipta therapy for 2 weeks followed by testing
