Breast Cancer Treatment Updates

Findings from a Phase II study to evaluate the use of talazoparib (a PARP inhibitor) in individuals with advanced PALB2-mutation breast cancer showed that it appeared effective in certain patients and appeared safe (with similar adverse events as those previously reported with this drug).1

There are several Phase II trials to evaluate PARP inhibitors in PALB2 carriers (as well as BRCA1 and BRCA2 carriers) with breast cancer at Vanderbilt and other locations across the country as outlined below:
