PARP inhibitors are a class of precision medicines used to treat cancers with specific mutations. This is a treatment option for advanced prostate cancer patients who are no longer benefiting from hormone therapy. 

A PARP is a protein that is involved in repairing damaged DNA. Research has proved that PARP is a driver of prostate cancer and that PARP inhibitors can suppress prostate cancer growth and progression.

There are two PARP inhibitor treatment options available to patients. 

Rubraca (Rucaparib)- First in its class PARP inhibitor for metastatic, castration-resistant prostate cancer patients. It has shown positive results in studies for patients with BRCA mutations. As a PARP inhibitor, Rubraca works to block cancer cells from repairing their damaged DNA. Rubraca is the first drug of its kind for prostate cancer, and is authorized for patients with highly advanced disease. 

Olaparib (Lynparza)- The FDA recently approved this PARP inhibitor for patients with metastatic castration-resistant prostate cancer (mCRPC). Olaparib is targeted to patients who have germline or somatic homologous recombination repair (HRR) gene mutations and have progressed following prior treatment with a new hormonal agent.

What I know now I wish I knew before…getting checked early can save your life.
