Frequently asked questions about Glycopyrronium MDI

What is Glycopyrronium MDI used for?

Glycopyrronium MDI is an investigational inhaled medicine being studied for the treatment of asthma. It is being developed as an add-on therapy given together with BFF, and the current research focuses on children aged 4 to less than 12 years with asthma.

What does Glycopyrronium MDI target?

Glycopyrronium MDI targets the muscarinic acetylcholine receptors CHRM1, CHRM2, CHRM3, CHRM4, and CHRM5. It acts as an antagonist at these receptors, which are involved in airway smooth muscle contraction and bronchoconstriction, so blocking them is intended to help relax the airways and improve lung function in asthma.

Who is developing Glycopyrronium MDI?

Glycopyrronium MDI is being developed by AstraZeneca PLC, which trades on the Nasdaq under the ticker AZN. AstraZeneca is the sponsor of the clinical program evaluating the drug in asthma.

What phase is Glycopyrronium MDI in?

Glycopyrronium MDI is in Phase 2 clinical development. It is an investigational small molecule and has not been approved by the FDA for asthma; it remains under study in a randomized, double-blind, controlled trial.

What clinical trials is Glycopyrronium MDI in?

Glycopyrronium MDI is being studied in the Phase 2 trial NCT07525375, which is currently recruiting. The trial has an enrollment of 69 participants and is being conducted in the United States, Argentina, Czechia, Hungary, Mexico, Poland, and Serbia.

Is Glycopyrronium MDI the same as GP MDI?

Yes, Glycopyrronium MDI is also known as GP MDI. Both names refer to the same AstraZeneca inhaled small molecule being studied in asthma, so searches for either name point to the same investigational asset.
