Efficacy and safety of veliparib in the treatment of advanced/metastatic breast cancer: a meta-analysis of phase II and III randomized controlled trials.

Abstract

We conducted a meta-analysis to evaluate the efficacy and safety of veliparib in the treatment of advanced/metastatic breast cancer. Databases were searched for relevant studies till June 2023. Six RCTs involving 1912 patients were included. The pooled analysis provided evidence that veliparib-containing regimens could significantly improve the PFS (HR: 0.71; 95% CI: 0.61-0.83; p < 0.0001), OS (HR: 0.87; 95% CI: 0.76-0.99; p = 0.03), and ORR (RR: 1.52; 95% CI:1.06-2.18; p = 0.02) than those of controls for treating advanced/metastatic breast cancer. Breast cancer patients with BRCA-mutation tended to have a better PFS than the BRCA-wildtype group, and patients with TNBC tended to associated with a longer PFS than the non-TNBC group. Veliparib could significantly increase the risk of anemia, leukopenia, neutropenia, diarrhea, stomatitis, fatigue, and peripheral neuropathy. Anemia and neutropenia should be well concerned. The veliparib-containing regimen was efficacious in treating advanced/metastatic breast cancer with a controllable safety factor.
