Gene clues may predict breast cancer drug success
NCT ID NCT02329639
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study examined whether specific gene variations influence how well metastatic breast cancer patients respond to chemotherapy with or without the drug bevacizumab. Researchers enrolled 307 women from Italy to compare outcomes and analyze genetic interactions. The goal was to understand which patients might benefit most from adding bevacizumab to standard chemotherapy.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * histologically confirmed HER2-negative MBC, treated with a first-line therapy including bevacizumab 10 mg/m2 i.v. on days 1 and 15 combined with first-line paclitaxel 90 mg/m2 i.v. on days 1,8 and 15,every 4 weeks, will be enrolled for the present pharmacogenetic study. MBC patients treated with a first-line chemotherapy without bevacizumab will also be enrolled as control goup. Exclusion Criteria: * histologically not confirmed HER2-negative MBC, and patients not treated with a first-line chemotherapy with or without bevacizumab.
