Study to Compare the Effects of Z7200 And Symbicort® Turbohaler on Respiratory Imaging Parameters in Asthmatic Patients

Asthma Clinical Trial

Official title: A Double Blind, Double Dummy, Randomized, Two Way Cross-over Study to Compare the Effects of Z7200 and Symbicort® Turbohaler on Functional Respiratory Imaging Parameters in Asthmatic Patients.

Status Completed

Clinical Trial Summary

Primary objective:

The primary objective of this study is to evaluate the effect of the products under investigation on functional respiratory imaging parameters and evaluate the particle deposition with Computational fluid dynamics (CFD).

Secondary Objectives:

The secondary objectives of this study were to assess the effect of test product and reference product on:

• lung function (spirometry and body plethysmography),

• exercise capacity (6-Minute Walking Test [6MWT] or equivalent method to measure exercise tolerance),

• dyspnea (Borg Category [C] Ratio [R] 10 [Borg CR10] scale and Visual Analogue Scale [VAS] dyspnea).

Furthermore, the safety of the test product and reference product was evaluated through monitoring of AEs throughout the study.

Clinical Trial Description

This study is conducted as a randomized, double blind, double dummy two-period crossover study in stable asthma patients treated in accordance with the Global Initiative for Asthma (GINA) guidelines.

On the first dosing day (Period 1, Visit 2), asthma stability was assessed based on review of pharmacologic treatment monitoring and FEV1 change from the previous visit. Patients were then randomized and allocated to one of two treatment sequences (i.e. test/reference or reference/test). Randomization codes were assigned strictly sequentially as patients became eligible for randomization. Patients received a single dose consisting of two inhalations of either the test product or the reference product, according to the assigned treatment sequence, in the presence of the Investigator or authorized site personnel. In addition, patients received two inhalations with matching placebo to the alternate treatment as a dummy inhaler to achieve double-blinding. All patients followed the same sequence of device inhalation, i.e. Symbicort or placebo Turbohaler first and Z7200 or placebo RS-01 inhaler second.

On the second dosing day (Period 2, Visit 3), patients underwent the same asthma stability check and procedures as in Visit 2. Patients received a single dose consisting of two inhalations of the other treatment (reference in case test product was administered at Visit 2 and vice versa) plus two inhalations with matching placebo to the alternate treatment. ;
