Visionary Science: Immuno-Oncology

Today, every member of our team remains committed to smartly and collaboratively accelerating the drug development process and the speed with which we can bring forward new approaches to treat people with cancer.

Understanding the Immune System and Cancer

The Past

In the 1950s, researchers proposed that the immune system patrols the body to detect and destroy tumor cells. Scientists and researchers had previously focused on cancer cells and treating cancer as a genetic disease.

The Present

Now the focus is shifting to the microenvironment in which cancer grows, including the immune system – an approach called immuno-oncology.

The Future

Immuno-Oncology has the potential to transform how physicians treat cancer and how patients benefit.
