The drug tested in this study is called Roflumilast. Roflumilast is being developed to treat people who have chronic obstructive pulmonary disease (COPD). This study investigated the effect of roflumilast 500 μg tablets once daily versus placebo on exacerbation rate, pulmonary function, and major adverse cardiovascular events (MACE) in COPD patients who were concomitantly treated with a fixed combination of long-acting beta-agonists (LABA) and inhaled glucocorticosteroids. The study was targeted to enroll approximately 1934 patients. Participants were randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which remained undisclosed to the patient and study doctor during the study (unless there was an urgent medical need): * Roflumilast 500 μg once daily * Placebo (dummy inactive pill) - this was a tablet that looked like the study drug but had no active ingredient Trial treatment was taken in the morning by mouth after breakfast with some water. The trial consisted of the following periods: * Single-blind baseline period (4 weeks) during which all patients received placebo. * Double-blind treatment period (52 weeks) during which patients received either roflumilast or matching placebo. * Safety follow-up (30 days after end of treatment (Vend) or premature discontinuation date) in case of ongoing Adverse Events at Vend, if necessary. * Follow-up visit 12 weeks after end of treatment, at Week 64 (VFU), only for patients who completed the trial as scheduled. This multi-center trial was conducted worldwide. The overall time to participate in this study was up to 64 weeks. Participants made multiple visits to the clinic which included a follow-up visit at week 64.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

1945 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.



Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

Inclusion Criteria: * Giving written informed consent * History of COPD (according to GOLD 2009) for at least 12 months prior to baseline Visit V0 associated with chronic productive cough for 3 months in each of the 2 years prior to baseline visit (with other causes of productive cough excluded) * Age ≥ 40 years * Forced expiratory volume after one second (FEV1)/forced vital capacity (FVC) ratio (post-bronchodilator) \< 70% * FEV1 (post-bronchodilator) ≤ 50% of predicted * At least two documented moderate or severe COPD exacerbations within one year prior to baseline visit * Patients must be pre-treated with LABA and ICS for at least 12 months before baseline Visit V0. Up to 3 months before baseline Visit V0 free or fixed combinations of LABA and ICS are allowed, including changes in dose, active substances, and brands. In the last 3 months before baseline Visit V0 patients must be pre-treated with fixed combinations of LABA and ICS at a constant dose (maximum approved dosage strength of the combination). * Former smoker (defined as smoking cessation at least one year ago) or current smoker both with a smoking history of at least 20 pack years Main Exclusion Criteria: * Exacerbations not resolved at first baseline visit * Diagnosis of asthma and/or other relevant lung disease * Known alpha-1-antitrypsin deficiency * Other protocol-defined exclusion criteria may apply
