Official title
A Pilot Study of Adjuvant Valproate for Patients With High Grade Sarcomas
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
For patients initially presenting with localized sarcoma the standard of care is surgery followed by with radiation therapy (if feasible). Subsequent or adjuvant cytotoxic based chemotherapy even for aggressive sarcoma histopathologies (as commonly done for colorectal cancer or breast cancer) is controversial since over 20 individual adjuvant randomized clinical trials have not been able to consistently demonstrate a statistically significant improvement in overall survival. Maturation or differentiation therapy provides an opportunity to fundamentally change the biology of the underlying cancer (and thus its overall prognosis) by promoting cellular maturation within that cancer. A change from a poorly 'differentiated/high grade' tumor to a well 'differentiated/low grade' tumor is attainable and can change an individual's median time of survival from months to decades. The investigators have significant preclinical data that differentiation therapy using a group of drugs referred to as histone deacetylase inhibitors (such as Valproate, also a commonly used and safe anti seizure medication) is feasible for sarcomas. This approach has not been clinically addressed in solid tumors. Since adjuvant therapy is controversial for sarcomas, and building on the investigators' preclinical data, adjuvant based differentiation therapy using valproate would be predicted to be both safe and potentially extremely beneficial in terms of a) increasing the time to disease recurrence, b) improving the histology upon recurrence; and c) improving overall survival in patients with sarcomas. Patients with high grade sarcomas will receive Valproate in the adjuvant setting daily and clinically/radiologically followed until recurrence. Relapse free survival, time to local failure, time to distant failure, overall survival, and comparative histopathology of primary and recurrence will be assessed.
