Summary

This study is testing the safety of a drug called ATGAM in one patient with moderate to severe aplastic anemia, a condition where the bone marrow doesn't make enough blood cells. The patient receives ATGAM by IV for 4 days and is monitored for 24 weeks for side effects. The goal is to confirm the drug's safety in Japanese patients.
