ENV-294 for adults with moderate-to-severe asthma — 12-week oral treatment

A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, 12-Week Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of ENV-294 in Adult Participants With Moderate-to-Severe Asthma

Phase 2 Interventional Enveda Therapeutics · NCT07301255

This 12-week study will test whether taking oral ENV-294 once daily can help adults with moderate-to-severe asthma who are already using inhaled corticosteroids and a LABA.

What this trial studies

Adults with physician-diagnosed moderate-to-severe asthma who are stable on an inhaled corticosteroid plus a long-acting beta2-agonist are screened and randomized to receive either oral ENV-294 or placebo once daily for 12 weeks after a screening period of up to 28 days. The trial monitors safety and tolerability, measures drug levels (pharmacokinetics) and biological effects (pharmacodynamics), and evaluates effects on lung function and asthma control. Key eligibility includes pre-bronchodilator FEV1 50–80% predicted, bronchodilator reversibility, ACQ-5 between 1.25 and 3.0, and a recent history of at least one exacerbation requiring systemic steroids or emergency care. Participants attend regular on-site visits at one of three Enveda sites for testing and follow-up in a randomized, placebo-controlled design.

Who should consider this trial

Good fit: Ideal candidates are adults 18–75 with physician-diagnosed moderate-to-severe asthma on stable ICS+LABA therapy, pre-bronchodilator FEV1 50–80% predicted, bronchodilator reversibility, ACQ-5 1.25–3.0, and a history of at least one exacerbation in the past year.

Not a fit: People with recent (within 4 weeks) moderate or severe exacerbations, a history of life-threatening asthma, other significant pulmonary disease, recent bronchial thermoplasty, or uncontrolled comorbid illnesses are unlikely to qualify and may not benefit.

Why it matters

Potential benefit: If successful, ENV-294 could provide an additional oral treatment option that improves lung function and asthma control for people not fully controlled on ICS/LABA.

How similar studies have performed: Phase 2 testing of novel oral asthma agents is relatively uncommon; while inhaled and biologic therapies have shown benefit in moderate-to-severe asthma, oral small-molecule approaches like ENV-294 have limited published clinical success so far.
