Since 1891, we’ve been guided by medical innovations and a mission of developing lifesaving treatments

Our work in cardiovascular diseases (diseases of the heart and blood vessels), vaccines, HIV, type 2 diabetes, and cancer has had a tremendous impact. Today we focus on scientific innovation to deliver medicines and vaccines that help millions of people around the world. We are committed to staying true to the philosophy of our founder, George W. Merck: Medicine is for the patients. Medicine is for the people.

Why are clinical trials important?

Our progress is due in large part to the important and tough scientific questions we set out to answer with our trials and, of course, the help of many participants who join our clinical trials.

Diversity in our clinical trials

MSD understands the importance of enrolling diverse participants in clinical research. And it’s about more than diversity, it’s also about equity.
