Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Summary

This phase 3 trial tests QL0911, a weekly injection, in 60 children aged 1 to 17 with chronic immune thrombocytopenia (ITP) who have low platelet counts. The goal is to see if the drug can safely raise platelet levels to reduce bleeding risk. Participants receive either QL0911 or a placebo, with doses adjusted based on weekly blood tests.

What this could mean

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

Active substance
QL0911 (a thrombopoietin receptor agonist given as a weekly injection)
What this could lead to
If it works, this could provide a new treatment option to safely raise platelet counts and reduce bleeding in children with chronic ITP.
What could go wrong
This is a relatively small trial (60 participants) and the drug may not work for all children. Side effects or the need for ongoing injections could limit its use.
