Opinion: PARP inhibitors in cancer—what do we still need to know?

WebPARP inhibitors (PARPi’s) have demonstrated efficacy in treating patients with germline (g)BRCA1/2, somatic (s)BRCA1/2, and gPALB2 mutations in clinical trials. However, patients with a poor performance status (PS) and those with severe organ impairment are often excluded from clinical trials and cancer-directed treatment. Webollowing two seminal publications in 2005 demonstrating greatly increased sensitivity of BRCA1/2 mutant cancer cells to poly(ADP-ribose) polymerase (PARP) inhibition 1 , 2 , PARP inhibitors (PARPi) have been extensively tested for their potential as single therapeutic agents based on the concept of tumor-specific synthetic lethality 3 – 5.
