Trial Outcomes & Findings for Clinical Endpoint Bioequivalence Study of Test and Reference Inhalation Products in Patients With COPD With Device Robustness (NCT NCT03137992)

NCT ID: NCT03137992

Last Updated: 2021-04-05

Results Overview

To show clinical bioequivalence in the efficacy of the test product as a single dose versus reference product based on the baseline adjusted mean change in forced expiratory volume in the first second (FEV1) area under the curve from time zero to 24 hours post dose (AUC0-24h) on day 1 zero to 24 hours post-dose (AUC0-24h). Baseline was defined as the average of the FEV1 values recorded at approximately 30 minutes and 15 minutes before dosing with study medication.

PRIMARY outcome

Timeframe: 0-24 hours after dosing on Day 1 of visits 2-4 over a period of approximately 6 weeks

Population: Per-Protocol population

To show clinical bioequivalence in the efficacy of the test product as a single dose versus reference product based on the baseline adjusted mean change in forced expiratory volume in the first second (FEV1) area under the curve from time zero to 24 hours post dose (AUC0-24h) on day 1 zero to 24 hours post-dose (AUC0-24h). Baseline was defined as the average of the FEV1 values recorded at approximately 30 minutes and 15 minutes before dosing with study medication.

PRIMARY outcome

Timeframe: 0-24 hours after dosing on Day 1 of visits 2-4 over a period of approximately 6 weeks

Population: Intention-To-Treat population

This measure is to demonstrate that test product as a single dose and reference product are superior to placebo based on the baseline adjusted mean change in forced expiratory volume in the first second (FEV1) area under the curve from time zero to 24 hours post dose (AUC0-24h) on day 1 zero to 24 hours post-dose (AUC0-24h). Baseline was defined as the average of the FEV1 values recorded at approximately 30 minutes and 15 minutes before dosing with study medication.
