“I am delighted to welcome Gary to the Conatus leadership team,” said Steven J. Mento, Ph.D., President and CEO. “His broad experience in drug development including fibrotic diseases will be particularly important as we move forward with the development of emricasan, our caspase inhibitor, targeted as a treatment for a variety of fibrotic diseases.”
