Identifying Mutations and Optimizing Use of PARP Inhibitors – Summary

 

William K. Oh, MD, highlights the growing significance of precision medicine and the role of genetic profiling in tailoring therapeutic strategies. Dr. Oh begins by outlining the importance of identifying DNA repair gene mutations, particularly BRCA1 and BRCA2, in prostate cancer patients. These mutations, which impair the cell’s ability to repair DNA damage, render the cancer more susceptible to treatments targeting DNA repair mechanisms, such as PARP inhibitors. 

Dr. Oh delves into the mechanisms of PARP inhibitors, which function by inhibiting the poly (ADP-ribose) polymerase (PARP) enzyme involved in DNA repair. By blocking this pathway, PARP inhibitors induce synthetic lethality in cancer cells harboring defective DNA repair genes, leading to cell death. 

Dr. Oh discusses the importance of patient selection based on genetic profiling and the potential for combining PARP inhibitors with other therapies, such as androgen receptor signaling inhibitors and immune checkpoint inhibitors, to enhance their efficacy. He reviews ongoing clinical trials exploring these combination strategies and their preliminary results.
