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.

Study Summary

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.

Primary Outcome

Efficacy of the investigational vaccine was measured by the rate of moderate and severe AECOPD from 1-month post dose 2 up to study end (i.e. rate expressed per year and calculated as the total number of events over the follow-up exposure time). The CIs of the rate is computed using a model which accounts for repeated events. Anthonisen criteria used to detect potential AECOPD: Worsening of 2 or more of the following major symptoms for at least 2 consecutive days: dyspnoea, sputum volume, sputum
