RecruitingDrug trialInvestigation of Profile-related Evidence Determining Individualized Cancer Therapy for Patients With Aggressive Malignancies and Poor PrognosesThis is a prospective, open-label navigational investigation designed to evaluate the feasibility of using molecular profile-based evidence to determine individualized cancer therapy for patients with aggressive malignancies. This is a non-randomized, histology-agnostic trial. Although there will be a case mix of histologies, the investigators now know that individual histologies are composed of a heterogeneous mix of molecular alterations. It is not clear whether one case mix is better or worse than another. Thus, the investigators are testing a strategy of molecular matching that may apply across different cancers.
