Summary

This study tests an investigational IV drug called efgartigimod in adults with primary immune thrombocytopenia (ITP), a condition where the immune system destroys platelets, raising bleeding risk. About 69 participants will receive either the drug or a placebo for up to 24 weeks, then all may receive the drug for up to 2 years. The goal is to see if the drug safely helps maintain safe platelet levels.
