How Does Jaypirca Block BTK?

Pirtobrutinib is a small-molecule noncovalent inhibitor of Bruton tyrosine kinase. It binds wild-type BTK and BTK with C481 mutations, reducing kinase signaling involved in B-cell proliferation, trafficking, chemotaxis, and adhesion.

Who Is Treated With Jaypirca?

Jaypirca is used in adults with relapsed or refractory mantle cell lymphoma after at least two systemic treatment lines including a BTK inhibitor. It is also used in adults with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma previously treated with a covalent BTK inhibitor.

How Is Jaypirca Dosed?

The recommended dose is 200 mg by mouth once daily until disease progression or unacceptable toxicity. Tablets are swallowed whole with water and can be taken with or without food. Severe kidney impairment, selected adverse reactions, and interacting CYP3A medicines can require dose changes or treatment interruption.

What Serious Risks Are Linked to Jaypirca?

Serious concerns include severe infections, major bleeding, low blood-cell counts, atrial fibrillation and other cardiac arrhythmias, second primary cancers, liver toxicity including drug-induced liver injury, and fetal harm. Complete blood counts and liver tests are monitored during treatment.
