Summary

This early-stage study tested how well healthy adults tolerate a new form of immune globulin (TAK-881) given under the skin with an enzyme that helps it spread. Sixty-four participants received different doses to see if they could complete the infusion without side effects. The goal was to gather safety and dosing information, not to treat any disease.
