OxaluRx is a preclinical company developing a small molecule, oral therapy to treat primary hyperoxaluria, a rare orphan metabolic disease. This rare form of hyperoxaluria is due exclusively to a genetic defect that causes a loss of specific enzymatic activity and the formation of kidney stones, leading to kidney damage and potentially failure. RiverVest is a founder of OxaluRx.

Scout is focused on delivering a new generation of gene therapies for pets to significantly improve the standard-of-care for multiple conditions. The technology approach is to express an appropriate level of a therapeutic protein in pet patients using adeno-associated viral vector (AAV) technology, delivered through simple injection.
