This prospective, open-label, two stage, pilot phase 2 trial evaluates the efficacy and safety of SM-88 in two cohorts of patients: 1) as maintenance therapy following standard primary or palliative treatments for Ewing's sarcoma patients with high risk of relapse or disease progression; and 2) as salvage therapy for patients with clinically advanced sarcomas. The primary objective is to evaluate the efficacy of SM-88, a combination metabolic cancer treatment, measured as positive efficacy events, including overall response, maintaining stable disease for ? 3 months, or progression free survival at least 1.5 times longer than the last prior line of treatment. Eligible patients will receive daily oral treatment with SM-88, which consists of D,L-alpha-metyrosine, used with methoxsalen, phenytoin, and sirolimus in continuous treatment cycles of 28 days. Treatment will continue until: 1) Symptomatic, clinical progression with radiographic progressive disease; 2) 48 weeks after documented complete response; or 3) evidence of unacceptable toxicity, or other decision to discontinue treatment
