Our Focus

Dedicated to developing treatment alternatives for patients
with Growth Hormone Deficiency (GHD)


XTEN® Technology

New compounds developed using the XTEN technology are expected to provide improvement in outcomes such as enhanced efficacy, fewer side effects, improved patient adherence and convenience, and enhanced stability.

Our Team

We are committed to building a first class organization to develop and commercialize somavaratan (VRS-317) and, most importantly, change the lives of people living with the burden of daily injection therapy for the replacement of hGH.
