Experimental: Treatment (sorafenib tosylate, valproic acid, sildenafil)
Patients receive sorafenib tosylate PO, valproic acid* PO, and sildenafil citrate PO BID for 4 weeks. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
* NOTE: Patients not receiving antiepileptic therapy begin valproic acid 1 week prior to the first day of sorafenib tosylate and sildenafil citrate.

- PFS [ Time Frame: 6 months ]The Kaplan-Meier method will be used to describe the time to progression and the median time to progression will be estimated, along with its 95% confidence intervals, for the entire population and for PDGFRa expression, respectively. Cox regression analysis will be used to evaluate baseline characteristics and any potential covariates.
- Overall best response rate (complete response + partial response) using RANO or Macdonald criteria. [ Time Frame: Up to 4 years ]Will be estimated for the entire study population and for the PDGFRa expressing high-grade glioma cohort, along with the 95% confidence intervals.
- Overall survival [ Time Frame: From the first day of study treatment until death by any cause, assessed up to 12 months ]The Kaplan-Meier method will be used to describe the time to overall survival and the median time to overall survival will be estimated, and along with its 95% confidence intervals, for the entire population and for PDGFRa expression, respectively. Cox regression analysis will be used to evaluate baseline characteristics and any potential covariates.
- Incidence of adverse events using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0 [ Time Frame: Up to 30 days following the end of study treatment ]
