Patent Summary

Niraparib, a PARP inhibitor, is used to treat prostate cancer in patients with DNA repair anomalies, such as BRCA-1 or BRCA-2 mutations. The treatment is effective in patients with castration-resistant prostate cancer, including those who have failed androgen receptor-targeted therapies. Niraparib's mechanism of action involves inducing DNA damage and inhibiting PARP-mediated repair, leading to tumor cell death. The treatment is administered orally and can be used in combination with androgen deprivation therapy.
