Healthy volunteers test dupilumab shot with enzyme helper

This early-stage study is testing whether adding an enzyme called berahyaluronidase alfa changes how the body processes dupilumab (Dupixent), a drug used for conditions like eczema and asthma. Forty healthy adults will receive a single injection of dupilumab either with or without the enzyme. The goal is simply to compare the drug levels and side effects between the two groups — there is no treatment benefit for participants.
