A number of clinical studies that address these issues are underway. Various PARP inhibitors are currently being tested alone or in combination with chemotherapeutic agents in the treatment of triple-negative, BRCA cients challenge, and metastatic breast cancer.
Chemotherapeutics tested go Ren carboplatin and cisplatin, topotecan, gemcitabine, DOXIL, TMZ, and paclitaxel.
