ClinConnect Summary
This clinical trial is studying a new treatment called HMPL-523 for adults with a condition known as Immune Thrombocytopenia (ITP). ITP is a blood disorder where the body doesn't have enough platelets, which are important for blood clotting. The main goals of the study are to assess how safe HMPL-523 is, how well people tolerate it, and if it can effectively raise platelet counts in those who haven't responded well to previous treatments.
To be eligible for this trial, participants must be at least 18 years old and have been diagnosed with ITP for at least three months. They should have tried at least one previous ITP treatment that didn't work well for them. However, certain people, such as those with other serious health issues or recent surgeries, may not qualify. If you join the study, you will receive the treatment and be monitored closely to evaluate its effects on your platelet levels and overall health. This trial is currently recruiting participants, so if you or someone you know is living with ITP, it may be worth considering.
