What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new asthma medication called AZD4604, which is inhaled regularly using a dry-powder inhaler. It targets adults whose moderate-to-severe asthma is not well-controlled by current treatments. The medication likely works by opening up the airways and reducing inflammation, making it easier to breathe.

Will I have to stop taking my current medications?

The trial requires participants to continue their current asthma medications, specifically medium-high dose inhaled corticosteroids (ICS) with long-acting beta-agonists (LABA), at a stable dose for at least 28 days before starting the trial. However, certain medications like systemic corticosteroids and some biologics must be stopped before the trial.

Are You a Good Fit for This Trial?

Adults aged 18-80 with moderate-to-severe asthma uncontrolled by current meds, who've had a severe asthma attack in the last year. They must have used their inhaler correctly during a run-in period and meet lung function criteria. Smokers or those with certain health conditions like recent serious infections or cancer are excluded.
