New long-term injection aims to control dangerous low platelet disorder

NCT ID NCT04812925

Ongoing Disease control Sponsor: argenx Source: ClinicalTrials.gov ↗

Summary

This trial is testing the long-term safety and effectiveness of a medication called efgartigimod, given as an injection under the skin, for adults with primary immune thrombocytopenia (ITP). The study aims to see if the treatment can help keep platelet counts at a safer level over a year, which could reduce the risk of serious bleeding. It is open to patients who successfully completed a previous 24-week study with the same drug.
