Trade Name: Zejula™
For which conditions is Zejula approved for? Zejula is approved for the maintenance of patients with ovarian cancer, fallopian tube cancer, or primary peritoneal cancer whose cancer has returned after a complete or partial response to treatment with a platinum-based chemotherapy.
What is the mechanism of action? Zejula is a PARP inhibitor. PARP (poly ADP ribose polymerase) is an enzyme that many cancers are dependent on in order to grow and spread. When the PARP enzymes are inhibited, cancer cell DNA is severely damaged, resulting in cell death.
How is Zejula typically given? Zejula is taken orally.
How are patients monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with Zejula. Typically, blood will be drawn to monitor functions of some organ systems, such as the kidneys or liver. Also, heart rate and blood pressure will be checked monthly for the first year and as needed after that. Patients may also undergo physical examinations, scans, or other measures to assess side effects and response to therapy.
