New antibody injection aims to tame COPD Flare-Ups

NCT ID NCT06707883

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 2 trial tests an injection called TQC2731 in 258 adults with moderate-to-severe COPD. The drug blocks a protein linked to airway inflammation. Researchers will measure how well it reduces the number of moderate or severe flare-ups over 24 weeks compared to a placebo.

What this could mean

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

Active substance

TQC2731 injection (a monoclonal antibody that blocks TSLP, a protein involved in airway inflammation)

What this could lead to

If successful, this could lead to a new treatment option that reduces the number of serious COPD flare-ups and improves lung function.

What could go wrong

This is an early Phase 2 trial with only 258 participants, so results may not apply to all COPD patients. The drug may not work better than placebo or could have side effects not yet seen.
