Participants will already be established on asthma biologic medications (either dupilumab or tezepelumab). Will will be clinical trials

Assessing airway twitchiness in patients with severe asthma on biologics as they reduce their inhaled corticosteriod dose

This study looks at whether people with severe asthma using new biologic medicines (dupilumab or tezepelumab) can safely lower their steroid inhaler dose. We want to see if the biologic can control asthma twitchiness well enough to reduce steroid use and its side effects.
