Uses

What is Jaypirca used for?

Jaypirca (pirtobrutinib) is commonly used to treat certain types of blood cancers, including mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), and small lymphocytic lymphoma (SLL).

Learn more about How Jaypirca Works for Mantle Cell Lymphoma (MCL).

Jaypirca may also be used for other conditions as determined by your healthcare provider.

How does Jaypirca work (mechanism of action)?

In some blood cancers, an enzyme called BTK is expressed on certain types of abnormal white blood cells, called B cells. These abnormal B cells cause certain types of lymphoma and leukemia. Jaypirca works by blocking BTK, which stops cancer cells from growing and multiplying.
