BACKGROUND: The randomised phase III TANIA trial demonstrated that continuing bevacizumab with second-line chemotherapy for locally recurrent/metastatic breast cancer (LR/mBC) after progression on first-line bevacizumab-containing therapy significantly improved progression-free survival (PFS) compared with chemotherapy alone (hazard ratio [HR]=0.75, 95% confidence interval [CI] 0.61-0.93). We report final results from the TANIA trial, including overall survival (OS) and health-related quality of life (HRQoL). PATIENTS AND METHODS: Patients with HER2-negative LR/mBC that had progressed on or after first-line bevacizumab plus chemotherapy were randomised to receive standard second-line chemotherapy either alone or with bevacizumab. At second progression, patients initially randomised to bevacizumab continued bevacizumab with their third-line chemotherapy but those randomised to chemotherapy alone were not allowed to cross over to receive third-line bevacizumab. The primary end point was second-line PFS; secondary end points included third-line PFS, combined second- and third-line PFS, OS, HRQoL and safety. RESULTS: Of the 494 patients randomised, 483 received second-line therapy; 234 patients (47% of the randomised population) continued to third-line study treatment. The median duration of follow-up at the final analysis was 32.1 months in the chemotherapy-alone arm and 30.9 months in the bevacizumab plus chemotherapy arm. There was no statistically significant difference between treatment arms in third-line PFS (HR=0.79, 95% CI 0.59-1.06), combined second- and third-line PFS (HR=0.85, 95% CI 0.68-1.05) or OS (HR=0.96, 95% CI 0.76-1.21). Third-line safety results showed increased incidences of proteinuria and hypertension with bevacizumab, consistent with safety results for the second-line treatment phase. No differences in HRQoL were detected. CONCLUSION: In this trial, continuing bevacizumab beyond first and second progression of LR/mBC improved second-line PFS but no improvement in longer-term efficacy was observed. The second-line PFS benefit appears to be achieved without detrimentally affecting quality of life. CLINICALTRIALSGOV: NCT01250379.
