Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension; at least one biopsiable lesion must be available; when imaging (DCE-MRI, DW-MRI and PET-computed tomography [CT] imaging) is being performed for secondary objectives (dose level III [or when the dose reaches at least 1,500 ug/m^2] and during the expansion phase) at least one lesion (>= 2 cm) not adjacent to the diaphragm will be required when measured by conventional techniques, including palpation, plain x-ray, CT, and MRI; a second lesion accessible for biopsy must also be present; patients must have at least one 'target lesion' to be used to assess response on this protocol as defined by Response Evaluation Criteria in Solid Tumors (RECIST); this may be one of the lesions mentioned above; tumors within a previously irradiated field will be designated as 'non-target' lesions

PRIMARY OBJECTIVES: I. To determine the safety and tolerability (toxicity profile) of EphA2-targeting DOPC-encapsulated siRNA (EphA2 siRNA) delivered via neutral liposome (1,2-dioleoyl-sn-glycero-3-phosphatidylcholine or DOPC) administered intravenously in patients with advanced/recurrent malignancies. II. To determine the maximal tolerated dose (MTD) or maximal administered dose (MAD) using a modified toxicity probability interval (mTPI) design. SECONDARY OBJECTIVES: I. To determine efficacy (EphA2 expression modulation) at the MTD or MAD. II. To evaluate the effect of EphA2 siRNA-DOPC on tumor and endothelial cell apoptosis. III. To record the clinical activity (objective response, duration of response, and time to treatment progression) of intravenous (IV) EphA2 siRNA -DOPC. IV. To describe the symptom burden of patients receiving siRNA-EphA2-DOPC treatment. EXPLORATORY OBJECTIVES: I. To determine the pharmacokinetic profile of siRNA-EphA2-DOPC in blood. II. To determine the effect of EphA2 siRNA-DOPC on tumor perfusion, apparent diffusion, and metabolism by radiographic imaging (dynamic contrast-enhanced-magnetic resonance imaging [DCE-MRI], diffusion weighted [DW]-MRI and fludeoxyglucose F-18-positron emission tomography [18FDG-PET]). III. To determine the impact of EphA2 siRNA-DOPC on surrogate biomarkers in blood (cell-free deoxyribonucleic acid [DNA], plasma/serum markers [vascular endothelial growth factor (VEGF), caveolin 1 (CAV1), soluble EphrinA1], and exosomes). OUTLINE: This is a dose-escalation study. Patients receive EphA2-targeting DOPC-encapsulated siRNA IV over 120 minutes on days 1 and 4. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up periodically.
