NCT ID: NCT03894969 Completed - Clinical trials for Respiratory Disorders

Study to Assess the Immunogenicity and Safety of GSK's Investigational Vaccine (GSK3277511A) When Given to Healthy Smokers and Ex-smokers After Administration of Shingrix Vaccine

Start date: April 23, 2019
Phase: Phase 2
Study type: Interventional

This study will provide information regarding the sequential administration of two vaccines adjuvanted with AS01. The aim of this study is to understand immunogenicity and safety of NTHi-Mcat vaccine when administered sequentially after Shingrix vaccine and to compare to the immunogenicity of NTHi-Mcat vaccine administered alone. This study will also provide information regarding whether a specific time period is required between the administration of these two different vaccines containing the same adjuvant- AS01 components. The population of this study will include healthy smokers and ex-smokers of 50 to 80 years of age which will be used as a proxy for the COPD population.

NCT ID: NCT03557645 Completed - Respiratory Failure Clinical Trials

Ventilator Hyperinflation and Hemodynamics

VHI-HD
Start date: November 5, 2017
Phase: N/A
Study type: Interventional

Ventilator hyperinflation (VHI) has been shown to be effective in improving respiratory mechanics, secretion removal, and gas exchange in mechanically ventilated patients; however, the literature is scarce concerning its safety and adverse effects. Thus, the aim of this study is to compare the hemodynamic repercussions of VHI in volume-controlled mode. In a randomized, controlled and crossover design, 24 mechanically ventilated patients will undergo 2 modes of ventilator hyperinflation (with and without an inspiratory pause) and a control intervention. Cardiac output, cardiac index, mean arterial pressure, pulmonary vascular resistance, systolic volume and other hemodynamic variables will be recorded during the interventions.

NCT ID: NCT03443427 Completed - Clinical trials for Respiratory Disorders

A Study to Test if a Third Dose of the Vaccine is Safe in Current and Former Smokers Aged 40 to 80 Years Old and to Gather Information on the Immune Response Following the Third Dose of the Vaccine

Start date: March 20, 2018
Phase: Phase 2
Study type: Interventional

The purpose of this study is to test two different vaccine schedules to be used for administering the investigational NTHi Mcat vaccine that will be targeting patients with chronic obstructive pulmonary disease (COPD) to prevent acute exacerbations. An acute exacerbation is when the breathlessness in COPD patients will get even worse than it normally already is, sometimes to the point where oxygen therapy is required. In previous studies, study participants have received two doses of the vaccine according to a 0, 2 month vaccination schedule, in addition to standard care. The current study will find out if a third dose of the study vaccine against NTHi/Mcat is safe and working well. The study will also investigate if the third dose of vaccine works best when given after 6 months or after 12 months.

NCT ID: NCT03281876 Completed - Clinical trials for Respiratory Disorders

A Study to Test if the Vaccine is Working Well in Chronic Obstructive Pulmonary Disease (COPD) Patients Aged 40 to 80 Years Old to Reduce Episodes of Worsening Symptoms and to Gather Further Information on Safety and Immune Response.

Start date: November 27, 2017
Phase: Phase 2
Study type: Interventional

The purpose of this study is to test if the vaccine is working well in COPD patients aged 40 to 80 years old to reduce episodes of worsening symptoms ("exacerbations") and to gather further information on safety and immune response. In the current study, COPD patients with a history of acute exacerbations will receive 2 doses of the investigational vaccine or placebo intramuscularly according to a 0, 2 month vaccination schedule, in addition to standard care. The effect of vaccination against two pathogens known to cause exacerbations (Non-typeable Haemophilus influenza [NTHi] and Moraxella catarrhalis [Mcat]) will be evaluated at pre-defined timepoints (scheduled study visits). In addition to the scheduled study visits, additional study visit(s) and/ or phone contact(s) will take place for each acute exacerbation of COPD occurring from first vaccination up to study conclusion.

NCT ID: NCT03201211 Completed - Clinical trials for Respiratory Disorders

A Long Term Follow-up Study up to 4 Years After Study Vaccination to Assess Immunogenicity and Safety of the Investigational Vaccine in Adults

Start date: June 22, 2017
Phase: Phase 1
Study type: Interventional

The purpose of this long-term follow-up of a Phase I study is to evaluate the kinetics of the antibody response to NTHi-Mcat antigens and long-term safety, in subjects aged between 50-71 years at the time of enrolment in the NTHi-Mcat-001 study. These subjects were previously exposed to two adjuvanted formulations of the NTHi-Mcat vaccine administered according to a 0, 2 months schedule in the NTHi-Mcat-001 (201281) study. The subjects that had received saline placebo controls will also be included in this follow-up study to make comparisons with the investigational vaccines. No vaccinations will be administered in this trial.

NCT ID: NCT03151395 Completed - Clinical trials for Respiratory Disorders

Occurrence of Potential Bacterial and Viral Pathogens in Stable Chronic Obstructive Pulmonary Disease and During Acute Exacerbations of the Disease, in Asia Pacific

Start date: August 25, 2017
Phase: N/A
Study type: Interventional

Since the infectious aetiology of AECOPD has been suggested to vary according to geographical region, the primary purpose of this study (which will be conducted in several countries in Asia Pacific) is to evaluate the occurrence of bacterial and viral pathogens in the sputum of stable COPD patients and at the time of AECOPD. Given the increasing and projected burden of COPD in the Asia Pacific region, this study will also evaluate the frequency, severity and duration of AECOPD, as well as the impact of AECOPD on health-related quality of life (HRQOL), healthcare utilisation and lung function.

NCT ID: NCT02658422 Completed - Clinical trials for Respiratory Disorders

Bioequivalence of GW483100 10 Milligram (mg) Tablets in Healthy Subjects Under Fasting Conditions

Start date: August 18, 2015
Phase: Phase 1
Study type: Interventional

This study is conducted to determine whether the test product (GW483100 10 mg containing montelukast sodium equivalent to 10 mg of montelukast) is bioequivalent to the reference montelukast sodium 10 mg tablets (innovator product) in healthy adult volunteers under fasting conditions. This is an open-label, balanced, randomized, single dose, two-way crossover study, enrolling 32 healthy human subjects to ensure at least 28 subjects complete the study. Each subject enrolled will participate in two treatment periods separated by a washout period of at least 7 days and no more than 14 days between dosing occasions. Total duration in the study for each subject will be approximately 7 weeks from screening to the subject's last visit.

NCT ID: NCT02322671 Completed - Clinical trials for Respiratory Disorders

Relative Bioavailability Study of Two Montelukast Sodium (GW483100) 5 Milligrams (mg) Chewable Tablets and One Reference Montelukast Sodium 5 mg Chewable Tablet in Healthy Adult Subjects

Start date: February 23, 2015

Subjects will be randomized to one of six sequences and administered one of the three treatments A, B or C in each treatment period, where Treatment A is 5mg chewable tablet of reference 5 mg montelukast sodium reference chewable tablets (innovator product), Treatment B is test formulation 1: 5mg montelukast sodium (GW483100) chewable tablet and Treatment C is test formulation 2: 5mg montelukast sodium (GW483100) chewable tablet. The treatment periods will be separated by a washout period of 7 to 14 days. Total duration in the study for each subject will be approximately 8 weeks from screening to the follow-up visit.
