Active clinical trials for "Asthma"

Double blind, multinational, multicentre, randomised, 2 arm parallel group study

Subjects will attend the unit for out-patient visits on Day 1, Day 7, Day 14 and Day 15 of each treatment period. The washout period between each treatment period will be a minimum of 10 days and maximum of 28 days. Subjects will participate in 3 treatment periods.

The aim of this study was to compare the efficacy and tolerability of the fixed combination beclomethasone/formoterol pMDI with that of budesonide/formoterol dry powder via Turbuhaler.

The purpose of this study is to determine the effectiveness and safety of SYMBICORT® pMDI (a medication approved by the Food and Drug Administration, FDA) in the African American population.

There has been considerable debate over the last 30 years about the interaction between asthma and parasitic infection. It has been suggested that at least part of the reason for the increasing prevalence of asthma in the developed world is a decrease in parasite infections resulting from improved living conditions with economic development. Our previous studies in Ethiopia suggest that hookworm infection may be particularly important in this process. To establish definitively whether parasites can protect against allergic disease, and specifically asthma, ultimately requires a randomised clinical trial of parasite infection in patients with asthma. We, the researchers at the University of Nottingham, have completed a study in normal volunteers to establish the dose of hookworms necessary to generate infection at the level shown to be protective in population surveys, and shown that infection is well tolerated. In addition, we have recently completed a randomized placebo-controlled clinical trial of hookworm infection in allergic patients with rhinitis which showed that there was no negative effect on bronchial responsiveness during the phase in the lifecycle where the hookworm larvae migrate through the lungs. Consequently, are now proceeding with the definitive randomized placebo-controlled trial of hookworm infection in people with asthma. This study will also provide us with the opportunity to investigate the cellular mechanisms of the effect of hookworm infection on the immune system.

This study is designed to determine if the investigational drug is effective and safe in individuals with asthma.

To compare the efficacy and safety of the fixed combination asthma drug Flutiform HFA MDI with its two components administered alone, fluticasone propionate and formoterol fumarate, in adult and adolescent patients with mild to moderate asthma.

The aim of this study is to evaluate the expression of IgE high affinity receptors (the part of the cell associated with allergic response) in patients suffering from uncontrolled severe asthma despite long term treatment with high dose of inhaled corticosteroid and long acting Beta-2 agonist.

The primary objective of this study is to assess the immunogenic potential of the liquid formulation of omalizumab administered over a period of 6 months in moderate to severe persistent allergic asthma patients 12 years of age or older, with no previous exposure to the drug (omalizumab naïve patients). The secondary objective of this study is to assess the safety of the liquid formulation of omalizumab in the same patients.

This study is designed to demonstrate that formoterol 12µg and 24µg delivered by a new inhalation device (Concept1) are equivalent to the corresponding dose of formoterol delivered by the Aerolizer device in terms of efficacy, in patients with persistent asthma.
