Recruiting PHASE2 Asthma

New treatment option for Asthma

Official title Dose-Ranging Study of LQ036 Single-Domain Antibody Nebulization Solution in Poorly Controlled Asthma

ClinicalTrials.gov ID: NCT07589439

What this study is testing

What is LQ036?

LQ036 is an investigational medicine, given as an once-daily inhaled treatment, being studied as a potential treatment for asthma.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
What is the goal of this study? The goal of this clinical trial is to find out whether the study drug LQ036 (a nebulized solution taken by inhaling through a nebulizer) works to improve lung function and asthma control in people whose asthma is not well controlled.
  • Phase 2: a mid-size study of how well it works
  • You might receive a placebo (an inactive treatment) instead of the study drug.
