Plan of investigation: patients will be treated with approved targeted agents, selected based on results of a molecular profiling test of the patient's tumor. Eligible patients will have exhausted standard treatment options, and their tumor must harbor a potentially actionable molecular variant as defined in the protocol. The study will provide a tumor board to help physicians understand the profiling test results and treatment options, and will enable insights about the utility of this approach. In addition, next generation sequencing will be performed on fresh tumor biopsies for additional biomarker discovery. Patients from the Netherlands and the USA will be included in two similar though independent protocols (DRUP and TAPUR), allowing data-exchange and empowering of both trials.
