Clinical trials

This research is being done to study the safety and feasibility of implanting and retrieving a microdevice that releases microdoses of 19 specific drugs or drug combinations as a possible tool to evaluate the effectiveness of several cancer drugs against metastatic renal cell carcinoma (RCC). The name of the intervention(s) involved in this study are: * Implantable Microdevice (IMD) * Surgery (excision of tumor) * Drugs used in this study will only include drugs already used as standard of care for the treatment of metastatic renal cell carcinoma (RCC)

This pilot study will assess the safety and feasibility of using an implantable microdevice to measure local intratumor response to chemotherapy and other clinically relevant drugs in malignant brain tumors. * The device involved in this study is called a microdevice. * The drugs used in this study will only include drugs already used systemically for the treatment of gliomas.
