MRVL Pet Pharmaceuticals is an early stage development company advancing novel treatments for cancer and osteoarthritis in companion animals. The global companion healthcare market has grown to $15.3 billion and is expected to reach $20.7 billion by 2025. Pets are living longer and developing more chronic diseases and while demand is strong, there simply aren’t drugs available for many of these diseases or conditions.
