NCT ID NCT04699604

First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 1 time

Summary

This study tests whether a skin test that measures histamine response can help doctors decide if adding an antihistamine (Levocetirizine) to standard asthma treatment improves control in children aged 6-17 with allergic asthma. About 300 African American/Black and Caucasian/White children will be randomly assigned to receive either the antihistamine or a placebo for 6 weeks, then switch. The goal is to see if the skin test predicts who benefits most from antihistamine therapy.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Levocetirizine (Xyzal)

What this could lead to

If successful, this could provide a simple skin test to identify which children with allergic asthma would benefit from adding an antihistamine to their current treatment.

What could go wrong

This is a Phase 3 trial, but it is still testing a biomarker approach. The antihistamine may not improve asthma control for all children, and results may vary by race or phenotype.
