Conditions
Chronic Obstructive Pulmonary Disease
Interventions
Drug: Placebo
Registration Number
NCT07190222
Lead Sponsor
Sanofi
Brief Summary

This is a parallel, Phase 2/Phase 3, 3-arm study to investigate the efficacy, safety, and tolerability of subcutaneous (SC) treatment with lunsekimig compared with placebo in adult participants (aged 40 to 80 years, inclusive) with inadequately controlled Chronic obstructive pulmonary disease (COPD) characterized by an eosinophilic phenotype.

Participation to the study consists of 3 periods:

* Screening period of up to 4 weeks

* Randomized intervention period of approximately 48 weeks

* Follow-up period: Approximately 8 weeks The study duration will be up to 60 weeks.

Detailed Description

All eligible participants will undergo subcutaneous administrations of lunsekimig or matching placebo during a 48-weeks treatment period

Primary Outcome Measures
NameTimeMethod
Annualized rate of moderatetosevere chronic obstructive pulmonary disease (COPD) exacerbationsFrom Baseline up to 48 weeks

The annualized moderate or severe COPD exacerbation rate up to 48 weeks treatment period compared to placebo

Secondary Outcome Measures
NameTimeMethod
Change from baseline in pre-Bronchodilator Forced Expiratory Volume in 1 second (pre-BD FEV1)From Baseline up to 48 weeks

The pre-Bronchodilator Forced Expiratory Volume in 1 second is defined as the volume of air exhaled from the lungs in the first second of a forced expiration.

Change from baseline in post-Bronchodilator Forced Expiratory Volume in 1 second (post-BD FEV1)From Baseline up to 48 weeks

The post-Bronchodilator Forced Expiratory Volume in 1 second is defined as the volume of air exhaled from the lungs in the first second of a forced expiration

Change from baseline in the SGRQ-C total scoreFrom Baseline up to 48 weeks

The St. George's Respiratory Questionnaire for patients with chronic obstructive pulmonary disease is derived from the St. George's Respiratory Questionnaire (SGRQ) and is designed to measure and quantify health status in adult patients with chronic airflow limitation. A global score ranges from 0 to 100 with lower scores indicating better quality-of-life.

SGRQ responder defined as an improvement of ≥4 points in the SGRQ-C total scoreFrom Baseline up to 48 weeks
Change from baseline in the Chronic airways assessment Test (CAAT) scoreFrom Baseline up to 48 weeks

The CAAT is an 8-item patient-reported outcome (PRO) measure designed to assess the impact of chronic airways diseases, including COPD, on patients' health status. The CAAT has a scoring range of 0-40, with higher scores indicating a greater impact of the disease on health status.

E-RS:COPD responder defined as an improvement of ≥2 points in the ERS:COPD total scoreFrom Baseline up to 48 weeks
CAAT responder defined as an improvement of ≥2 points in the CAAT) total scoreFrom Baseline up to 48 weeks
Change from baseline in the E-RS:COPD total scoreFrom Baseline up to 48 weeks

The Evaluating Respiratory Symptoms in Chronic Obstructive Pulmonary Disease (E-RS:COPD) is an 11-item patient-reported outcome (PRO) measure that evaluates the severity of respiratory symptoms in patients with stable COPD. The total score ranges from 0 to 40, with higher scores indicating more severe respiratory symptoms.

Annualized rate of severe COPD exacerbationsFrom Baseline up to 48 weeks
Time to first moderate or severe COPD exacerbationFrom Baseline up to 48 weeks

Time to first occurrence of moderate to severe COPD exacerbation up to 48 weeks

Time to first severe COPD exacerbationFrom Baseline up to 48 weeks

Time to first occurrence of severe COPD exacerbation up to 48 weeks

Incidence of participants with TEAEs, including AESIs, and SAEsFrom Baseline up to 56

Treatment-Emergent Adverse Events (TEAEs), Adverse events of Special Interest (AESIs), Serious Adverse Events (SAEs)

Incidence of potentially clinically significant laboratory abnormalitiesFrom Baseline up to 56 weeks
Serum concentration of lunsekimigFrom Baseline up to 56 weeks
Incidence and titer of antidrug antibodies (ADAs)From Baseline up to 56 weeks
