A Phase II Trial of Panobinostat, a Histone Deacetylase Inhibitor, in the Treatment of Patients with Refractory Metastatic Renal Cell Carcinoma

Abstract

Purpose: To evaluate the activity of panobinostat in refractory renal carcinoma. Patients and Methods: Patients with advanced clear cell renal carcinoma who had received previous therapy with at least one angiogenesis inhibitor and one mTOR inhibitor were treated with panobinostat 45 mg orally twice a week, and were reevaluated after 8 weeks.

Results: Twenty patients were treated with no objective responses. All patients progressed or stopped treatment prior to the 16-week reevaluation. Panobinostat was generally well-tolerated.

Conclusion: Panobinostat had no activity in this group of patients with refractory renal carcinoma. Further development of panobinostat in renal carcinoma is not recommended.
