Key clinical point: The combination of apatinib and vinorelbine lowered the risk for disease progression and was well tolerated in patients with metastatic triple-negative breast cancer (TNBC) who had failed first or second-line treatment.
Major finding: There was a significant improvement in progression-free survival with apatinib + vinorelbine vs only vinorelbine (hazard ratio 1.82; P = .026). Leukopenia (42.4% vs 40.6%) and granulocytopenia (57.6% vs 31.3%) were the most frequent grade 3-4 hematologic adverse events in the apatinib + vinorelbine vs vinorelbine group.
Study details : Findings are from the phase 2, NAN study including 66 patients with recurrent or metastatic TNBC who had failed first or second-line treatment and were randomly assigned to receive apatinib + vinorelbine or vinorelbine.
