Lonafarnib in Metastatic Breast Cancer

• Status: Terminated
• Trial end date: 2010-11-01
• Target enrollment: 0
• Participant gender: All

Summary

A published phase 2 study reported that lonafarnib was administered as a single agent via continuous or intermittent oral dosing to 76 women with advanced breast cancer who were previously treated with chemotherapy and/or with endocrine therapy. Objective response rates of approximately 10% were observed. This study will determine the rate of progression-free survival of patients with metastatic breast cancer who receive lonafarnib.

• Phase: Phase 2
