A Phase II Multiple-Arm, Open-Label, Randomized Study of PARP Inhibition (Veliparib; ABT-888) and Anti-PD-L1 Therapy (Atezolizumab; MPDL3280A) Either Alone or in Combination in Homologous DNA Repair (HDR) Deficient Triple Negative Breast Cancer (TNBC)
Breast - Female | Phase I
What is the purpose of this trial?
This randomized phase II trial studies how well veliparib and atezolizumab work either alone or in combination in treating patients with stage III-IV triple negative breast cancer. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as atezolizumab, may interfere with the ability of tumor cells to grow and spread. It is not known whether giving veliparib and atezolizumab either alone or in combination would work better in patients with triple negative breast cancer.
