Dasatinib and Ipilimumab in Treating Patients With Gastrointestinal Stromal Tumors or Other Sarcomas That Cannot Be Removed by Surgery or Are Metastatic

This phase I trial studies the side effects and best dose of dasatinib when given together with ipilimumab in treating patients with gastrointestinal stromal tumors or other sarcomas that cannot be removed by surgery or have spread to other places in the body. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as ipilimumab, can block tumor growth in different ways by targeting certain cells. Giving dasatinib together with ipilimumab may be a better treatment for patients with gastrointestinal stromal tumors or other sarcomas.
