LBH589 Treatment for Refractory Clear Cell Renal Carcinoma

• Status: Completed
• Trial end date: 2010-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Inhibition of histone deacetylase (HDAC) provides a novel approach for cancer treatment. LBH589, an oral HDAC inhibitor, has been well tolerated in phase I trials and has shown activity against several types of cancer. In this nonrandomized phase II trial, we are investigating the activity of LBH589 in the treatment of patients with refractory clear cell renal carcinoma.

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