Enrollment: 14
Study Start Date: September 2012
Study Completion Date: November 2014
Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: valproic acid Drug: Valproic Acid
Other Name: sodium valproate

Detailed Description:

Valproic acid is a known histone deacetylase inhibitor. In addition to activating apoptosis pathways, cell differentiation and downregulating expression of growth factors, it also promotes radiosensitization.

Most patients with Head and Neck squamous cell carcinoma are diagnosed with locally advanced disease, in which long term disease control is still a challenge. The incorporation of epigenetic regulation into standard treatment could improve results of definitive platinum-based chemoradiation in such patients.
