This is a Phase 1, open-label, non-randomized, dose-escalation study to determine the maximum tolerated dose (MTD), safety, tolerance, and pharmacologic profile of EZN-2968, a locked nucleic acid antisense oligonucleotide against hypoxia-inducible factor 1α administered as a 2-hour intravenous (i.v.) infusion weekly for 3 weeks per 6-week cycle. In patients treated at a recommended Phase 2 dose of EZN-2968, dose intensification will proceed by maintaining the dose, but gradually increasing the number of doses per 6-week cycle. Up to 3 intensification cohorts will receive the recommended Phase 2 dose of EZN-2968.

• Patients who have failed standard therapy and have no known effective therapy available to them
• Patients may have a tumor amenable to biopsy
• Measurable or evaluable disease.
• Age 18 years or older

Exclusion Criteria: Patients meeting any of the following exclusion criteria will not be eligible for enrollment.

• Concurrent serious medical illness
• Known, clinically suspected, or history of central nervous system (CNS) tumor involvement
• Prior chemotherapy, immunotherapy, investigational agent, or other therapy used to treat the cancer within 4 weeks (6 weeks for prior treatment with mitomycin C or nitrosoureas) before the scheduled administration of EZN-2968. Luteinizing hormone-releasing hormone (LHRH) agonist therapy is permitted for patients with hormone refractory prostate cancer.
