Summary

This study tests whether daratumumab, a drug used for certain cancers, is safe for people with antiphospholipid syndrome (APS), an autoimmune disorder that raises blood clot risk. Up to 22 adults will receive weekly infusions for 8 weeks at different doses. The main goal is to check for serious side effects during dose escalation.
