Our vision is to improve the lives of the millions of people with cardiovascular disease and diabetes, and to work tirelessly to eliminate these diseases. Every year 19 million people around the world die from cardiovascular and metabolic diseases. This tremendous global burden compels us to develop new therapies that will change the face of these diseases and, ultimately, eliminate them. We focus on finding and developing truly transformational therapies that target underlying disease pathways, important pathways, and novel mechanisms of action. We have a very successful track record demonstrated by the development and recent successful launches of our products for the treatment of patients suffering from thrombosis and type 2 diabetes. And we continue to seek and develop the next generation of transformational cardiovascular and metabolic therapies.
Focusing on the Most Devastating Diseases of Our Lifetime
We want to drive down the rates of cardiovascular and metabolic diseases with our science, innovation, and solutions. We are already transforming the treatment of type 2 diabetes and thrombosis with our products. And while these important products continue to change the way doctors are treating diabetes and thrombosis, we are also focused on finding the next wave of transformational treatments for cardiovascular and metabolic diseases that will prevent, intercept, and cure devastating diseases.
