Study of Effect of CSJ117 on Symptoms, Pharmacodynamics and Safety in Patients With COPD

This is a randomized, participant- and investigator-blinded, placebo-controlled, parallel group, multicenter study with two fixed-dose levels of CSJ117 (4 mg, 8 mg) administered once-daily via oral inhalation over 12 weeks in participants with COPD, prone for exacerbations and symptomatic at baseline despite background maintenance triple therapy (inhaled corticosteroids/long acting beta-2 agonist/long acting muscarinic antagonist (ICS/LABA/LAMA) combination, standard of care in this population) for at least three months prior to screening.

The study will include:

• Screening period of up to 2 weeks to assess eligibility.
• Run-in period of 4 weeks where participants will be placed on fixed-dose triple background therapy (ICS/LABA/LAMA) that will be used until the patient's last study treatment.
• Treatment period of 12 weeks. Participants will be stratified by eosinophil levels and then randomized 1:1:1 to either 4 mg CSJ117, 8 mg CSJ117, or placebo.
• Follow-up period of 55 days following the last dose of study drug. The primary objective of the study is to assess the effect of CSJ117 on disease/symptom burden after 12 weeks of treatment.

Inclusion criteria

• Male and female COPD patients aged ≥40 years, who have signed an Informed Consent Form prior to initiation of any study-related procedure
• Current or ex-smokers who have a smoking history of at least 10 pack years
• Patients who have been treated with a triple combination of LABA/LAMA/ICS for the last 3 months prior to screening
• Patients with a documented diagnosis of COPD for at least 1 year prior to screening visit

Exclusion criteria

• Patients with a past or current medical history of asthma
• Patients who have had a COPD exacerbation that required treatment with antibiotics and/or oral corticosteroids and/or hospitalization, or a respiratory tract infection in the 4 weeks prior to screening, or hospitalization between screening and prior to treatment.
• Use of other investigational drugs (approved or unapproved) within 30 days or 5 half-lives prior to screening, or until the expected pharmacodynamic effect has returned to baseline (e.g., biologics), whichever is longer; or longer if required by local regulations
• Pregnant or nursing (lactating) women, and women of childbearing potential not willing to use acceptable effective methods of contraception during study participation
• Patients with a body mass index (BMI) of more than 40 kg/m2 Other protocol-defined inclusion/exclusion criteria may apply
