A Study to Determine the Antitumor Activity and Evaluate the Safety of MKC-1

• Status: Completed
• Trial end date: 2008-11-01
• Target enrollment: 0
• Participant gender: All

Summary

This phase 2 study will determine the antitumor activity, based on the objective rate, of oral MKC-1, administered twice daily for 14 consecutive days every 4 weeks, in patients with advanced or metastatic breast carcinoma. The study will also evaluate the safety and response duration in patients, time to tumor progression, and overall survival in patients following MKC-1 therapy.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
