Can an asthma drug tame stubborn keloid scars?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Men and women between the ages of 18 and 65 at the time of dupilumab initiation. * Subjects must have either one keloid with ≥ 2 cm length-wise or at least two keloids with ≥ 0.4 cm (width) x 0.4 cm (length) * Subjects must be able to understand and communicate with the investigator and comply with the requirements of the study and must give a written, signed and dated informed consent before any study related activity is performed.
