Capecitabine + Bendamustine in Women With Pretreated Locally Advanced or Metastatic Her2-negative Breast Cancer

• Status: Completed
• Trial end date: 2018-03-15
• Target enrollment: 0
• Participant gender: Female

Summary

Patients with pretreated, Her2-negative, advanced breast cancer will receive chemotherapy with capecitabine and bendamustine for a maximum of eight cycles and afterwards capecitabine alone until disease progression or unacceptable toxic effects. Safety assessments will be conducted in 3-weekly intervals, efficacy assessments (CT or MRI) will be conducted every 9 weeks.

Aim of this study is to determine whether treatment with capecitabine in combination with bendamustine is efficacious and safe.

• Phase: Phase 2
