Why that species
Not stated in public reviews
Surrogate molecule
Yes: representative nonclinical product (RVV-transduced human keratinocytes on human acellular dermal matrix)
“In vivo pharmacology studies were conducted with a nonclinical product representative of ZEVASKYN comprised of vector (the RVV, or vectors similar to the RVV)-transduced human keratinocytes (cells alone or cells grown into sheets) affixed to a block of human acellular dermal matrix or dermis.”
