入选标准

  • The participant must be between the ages of 18 and 75 inclusive at the time of signing the informed consent.
  • Moderate to severe asthma diagnosed by a physician for ≥ 12 months according to stages 4 and 5 of the Global Initiative for Asthma (GINA ).
  • Participants on existing therapy with medium to high doses of ICS (≥500 μg fluticasone propionate daily or comparable ICS dose in combination with at least one additional controller (e.g., long-acting beta agonist [LABA], leukotriene receptor antagonist [LTRA], long-acting muscarinic Antagonist [LAMA], methylxanthines) for at least 3 months.
  • ≥ 1 severe asthma exacerbation in the past year, with at least one exacerbation during treatment with medium to high doses of ICS (≥ 500 μg fluticasone propionate daily or one dose of ICS comparable).
  • Participants with pre-BD forced expiratory volume in 1 second (FEV1) > 40% and < 80% of predicted normal at the screening visit.
  • 5-item ACQ-5 score >1.5 at randomization.
  • Participants with at least 12% reversibility and 200 mL post-BD FEV after administration of albuterol/salbutamol or levalbuterol/levosalbutamol at screening or documented history of a reversibility test.
  • Weight ≥40 kg and ≤150 kg at the randomization visit.

排除标准

  • Chronic lung disease other than asthma.
  • Hepatitis B, C or HIV.
  • Pregnant or breastfeeding.
  • History (within last 2 years prior to Baseline) of prescription drug or substance abuse, including alcohol, considered significant by the Investigator.
  • Any prior use of anti-OX40 or anti-OX40L mAb, including amlitelimab
  • Sensitivity to any of the study interventions, or components thereof, or drug or other allergy that, in the opinion of the Investigator, contraindicates participation in the study
  • Current or former smoker including active vaping of any products and/or marijuana with cessation within 6 months of screening or history of >10 pack-years.
  • Participants who experience a deterioration of asthma that results in emergency treatment or hospitalization, or treatment with systemic steroids at any time from 1 month prior to screening.
  • Suspicion of, or confirmed, coronavirus disease 2019 (COVID-19) infection during the screening period including known history of COVID-19 infection within 4 weeks prior to Screening; mechanical ventilation or extracorporeal membrane oxygenation (ECMO) secondary to COVID-19 within 3 months prior to Screening; COVID-19 infection who have not yet sufficiently recovered to participate in the procedures of a clinical trial.
  • Active infection or history of clinically significant infection
  • 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.
  • Active or latent tuberculosis (TB)
  • A history of malignancy of any type (excluding basal and squamous cell skin cancer and in situ cervical carcinoma that has been excised and cured >3 years prior to baseline).
  • History of solid organ transplant.
