Study of Lunsekimig (SAR443765) Compared With Placebo in Adults With High-risk Asthma

Phase 2
Recruiting
Conditions
Asthma
Interventions
Drug: Short-Acting Beta Agonists (SABA)
Drug: Placebo
Drug: Fluticasone/salmeterol
Drug: Budesonide/formoterol
Registration Number
NCT06676319
Lead Sponsor
Sanofi
Brief Summary

This is a parallel-group, Phase 2, randomized, double-blind, placebo-controlled, 2-arm study for the treatment of asthma.

The purpose of this study is to assess the efficacy, safety, and tolerability of add-on therapy with SC lunsekimig compared with placebo in male and female participants (aged 18 to 80 years, inclusive) with asthma, who are not currently eligible for biologic treatments.

Study details include:

* The study duration will be approximately 64 weeks for participants not transitioning into the LTS study and approximately 60 weeks for participants transitioning into the LTS study.

* The investigational treatment duration will be up to approximately 52 weeks.

* The number of visits will be 18.

Inclusion Criteria
  • Physician-diagnosed mild-to-moderate asthma for more than 12 months based on GINA guidelines.
  • At least 1 asthma exacerbation in the year prior to Screening (Visit 1).
  • Pre-BD FEV1 of equal or more than 40% of predicted normal (by Global Lung Function Initiative [GLI] standards) at Screening (Visit 1).
Exclusion Criteria

Participants are excluded from the study if any of the following criteria apply:

  • Other severe lung diseases (eg, chronic obstructive pulmonary disease [COPD]. bronchiectasis, idiopathic pulmonary fibrosis, etc) which may impair lung function.
  • Participants who experience a deterioration of asthma that results in emergency treatment or hospitalization, or treatment with systemic steroids within 1 month prior to the Screening (Visit 1) (counting from the date of completion of treatment for asthma exacerbation).
  • Participants who have experienced an upper or lower respiratory tract infection within the 4 weeks prior to Screening (Visit 1).
  • Known history of, or suspected, significant current immunosuppression, including history of invasive opportunistic or helminthic infections despite infection resolution or otherwise recurrent infections of abnormal frequency or prolonged duration.
  • Evidence of any infection requiring systemic anti-infective treatment within 2 weeks before Screening (Visit 1) or during the screening period. Significant viral infections within 2 weeks before Screening (Visit 1) or during the screening period even if the participant has not received systemic antiviral treatment (eg, influenza receiving only symptomatic treatment).
  • Participants with active tuberculosis (TB), latent TB, a history of incompletely treated TB, suspected extrapulmonary TB infection, or who are at high risk of contracting TB (such as close contact with individuals with active TB), or received Bacillus Calmette-Guérin (BCG)-vaccination within 12 weeks prior to Screening (Visit 1).
  • Severe concomitant illness that would in the Investigator's opinion inhibit the participant's participation in the study, including for example, but not limited to, hypertension, renal disease, neurological conditions, heart failure, and pulmonary disease.

Primary Outcome Measures
NameTimeMethod
Annualized rate of asthma exacerbation eventsFrom baseline up to 52 weeks

Asthma exacerbation event defined as: worsening of asthma requiring the use of systemic corticosteroids for ≥3 days; or hospitalization or emergency room visit due to asthma and requiring the use of systemic corticosteroids

Secondary Outcome Measures
NameTimeMethod
Change from baseline in prebronchodilator (BD) forced expiratory volume in 1 second (FEV1)From baseline to week 52
Change from baseline in Asthma Control Questionnaire5 (ACQ-5) scoreFrom baseline to week 52

The ACQ-5 is a questionnaire that measures the adequacy of asthma control and any changes in asthma control that may occur spontaneously or as a result of treatment. The ACQ-5 has five questions on the asthma symptoms and patients are asked to recall how their asthma has been during the previous week and to respond on a 7-point scale for each question (0 = no impairment, 6 = maximum impairment). The ACQ-5 score is the mean of the 5 questions and, therefore, between 0 (totally controlled) and 6 (severely uncontrolled). A high score indicates low asthma control.

Change from baseline in FeNO levelFrom baseline to week 52
Annualized rate of loss of asthma control events (LOAC) eventsFrom baseline to week 52

Annualized rate of LOAC events defined by 1 or more of the following criteria:

* ≥30% reduction from baseline in morning PEF on 2 consecutive days

* ≥6 additional reliever puffs of SABA in a 24-hour period (compared to baseline) on 2 consecutive days OR ≥4 additional puffs of low-dose budesonide/formoterol in a 24-hour period (compared to baseline) on 2 consecutive days

* Worsening of asthma requiring the use of systemic corticosteroids for ≥3 days

* Hospitalization or emergency room visit because of asthma, requiring systemic corticosteroids (asthma exacerbation event)

Annualized rate of asthma exacerbations requiring hospitalization or emergency room or urgent care visitFrom baseline to week 52
Total systemic corticosteroid dose exposureFrom baseline to week 52
Change from baseline in Asthma Quality of Life Questionnaire Standardized (AQLQ{S}) scoresFrom baseline to week 52
Change from baseline in the Asthma Daytime Symptom Diary (ADSD) daily morning and evening scoreFrom baseline to week 52
Serum lunsekimig concentrationsFrom baseline to week 56
Incidence and titer of anti-drug antibodies (ADA) against lunsekimigFrom baseline to week 56
Incidence of participants with treatment-emergent adverse events (TEAEs), including local reactions, adverse events of special interests (AESIs), serious adverse events (SAEs)From baseline to week 56
