Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* Phase 1a will involve dose escalation to determine the maximum tolerated dose (MTD). The MTD will be determined on the basis of the results from the safety evaluation.
* Phase 1b will involve cohort expansion at one or more dose levels to determine the recommended Phase 2 dose. The recommended Phase 2 dose, which may differ from the MTD, will be determined on the basis of results from safety, activity, and pharmacologic and correlative studies.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Histologically or cytologically confirmed diagnosis of metastatic prostate adenocarcinoma
3. Ongoing gonadal androgen-deprivation therapy with LHRH analogs or orchiectomy. Patients without orchiectomy must receive effective LHRH analog therapy during the study
4. Testosterone \< 50 ng/dL
5. Progressive disease after androgen deprivation - with all 3 of the following criteria:PSA evidence of progressive prostate cancer; PSA ≥ 5 ng/mL increasing on at least 2 successive occasions, at least 2 weeks apart. If confirmatory PSA \< screening PSA, additional test for increasing PSA is needed
6. Patients receiving anti-androgen agent as part of primary androgen ablation: disease progression after stopping the anti-androgen agent. This disease progression is defined: 2 consecutive increasing PSAs ≥ 2 weeks apart, or documented osseous or soft tissue progression. Flutamide patients: at least one of the PSAs ≥ 4 weeks after stopping flutamide. Bicalutamide or nilutamide patients: at least one PSA ≥ 6 weeks after stopping the anti-androgen agent.
7. Patients who failed standard therapy or who, after physician discussion, wish to delay chemotherapy
8. Age ≥ 18 yrs
9. ECOG Score: 0-1
10. Albumin ≥3.0 g/dL
11. ANC ≥ 1,500/µL
12. Plts ≥ 75,000/µL
13. Hgb ≥ 9.0 g/dL
14. Serum Creat. ≤ 1.5xULN or Calc Creat. clearance ≥ 60 mL/min
15. Tot bili ≤ 1.5xULN
16. AST; ALT: ≤ 2.5xULN
Exclusion Criteria
2. Concurrent serious medical illness that might interfere with protocol compliance
3. Known chronic infectious disease, eg. AIDS or hepatitis
4. Male patient of reproductive capacity unwilling to use methods appropriate to prevent pregnancy. In the UK, double-barrier contraception required. Patients should continue to use contraception for 3 months after stopping EZN-4176 due to potential for prolonged half-life of EZN-4176 in the liver.
5. History of CNS tumor involvement
6. Other hormonal therapy, eg. megestrol acetate (Megace®), finasteride (Proscar®), dutasteride (Avodart®), or any herbal product known to decrease PSA (e.g., saw palmetto, PC-SPES, and PC-HOPE)
7. \> 10 mg/day of prednisone or equivalent systemic corticosteroid within 4 weeks of first dose of EZN-4176
8. Initiation of bisphosphonates within 4 weeks of enrollment. Patients receiving stable doses of bisphosphonates with subsequent tumor progression may continue to receive this medication; however, initiation of bisphosphonates is not allowed during the study.
9. Therapy with supplements or complementary medicines/botanicals within 4 weeks of first dose of study drug, except for any combination of the following: Conventional multivitamin supplements; Selenium; Lycopene; and Soy supplements
10. Prior chemotherapy, immunotherapy, investigational therapeutic agent, or other therapy used to treat the cancer within 4 weeks (6 weeks for prior treatment with mitomycin C or nitrosoureas) before first dose of EZN-4176
11. Radiation or radioactive treatment within 4 weeks before first dose of EZN-4176. Single-fraction palliative radiation is allowed within 2 weeks before first dose of EZN-4176
12. Lack of recovery from any reversible side effects (except alopecia and Grade 1 or 2 neuropathy) to Grade 0 or 1 toxicity related to administration of an investigational therapeutic agent, chemotherapy, immunotherapy, radiotherapy, or other agents previously used to treat the cancer
13. Current participation in another clinical study with an investigational therapeutic agent and/or use of an investigational therapeutic drug (not including investigational use of an approved drug) in the 30 days before first dose of EZN-4176
14. Inability to comply with study protocol
15. Full anticoagulation therapy
