About this trial
This study will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and potential efficacy of ENV-294 in adults with moderate to severe asthma who are receiving background treatment with inhaled corticosteroids (ICS) and long-acting beta₂-agonists (LABA).
Participants will take oral ENV-294 or placebo once daily for 12 weeks. The study includes a screening period of up to 28 days before randomization to confirm eligibility. Study visits and assessments will be conducted to monitor safety, measure drug levels in the blood, and evaluate effects on asthma control and lung function.
