A Pilot Study of EZN-2968, an Antisense Oligonucleotide Inhibitor of HIF-1alpha, in Adults With Advanced Solid Tumors With Liver Metastases

Completed · Phase 1

Conditions studied: Neoplasms, Liver Metastases

In brief

Background: \- A protein called HIF is believed to be involved both in forming cancers and helping them to grow after they are formed. EZN-2968 is a new type of cancer drug that goes into the cancer cell and switches off the production of the HIF protein. Researchers are interested in testing EZN-2968 in people who have liver cancer because studies have shown that this drug travels to the liver and stays there when the drug is given through a vein. Objectives: \- To determine the safety and effectiveness of EZN-2968 on liver cancer. Eligibility: \- Individuals 18 years of age and older who have been diagnosed with liver cancer that has not responded to standard treatments. Design: * Participants will have an initial screening visit with a physical examination, blood and urine tests, and imaging studies to assess tumor size. Tumor biopsies may also be taken for research purposes. * Participants will have an undefined number of 6-week treatment cycles of EZN-2968, given once a week for 3 weeks followed by 3 weeks without the drug. * During each cycle, participants will have additional blood tests and imaging scans to assess tumor response to treatment. * Cycles of treatment with EZN-2968 may continue until the treatment is not effective, illness requires participants to stop taking the study drug, or the participant chooses to withdraw from the study.

You may qualify if…

Patients must have histologically or cytologically confirmed diagnosis of solid tumor. The diagnosis should be confirmed by the Laboratory of Pathology, NIH.
Patients must have disease that is not amenable to potentially curative resection.
Disease must be amenable to biopsy, and patients must be willing to undergo tumor biopsies.
Patients must have failed at least one line of prior therapy for metastatic disease or have a disease for which no standard curative therapy exists. Prior anti-angiogenic therapy is allowed.
Age (Bullet)18 years. Because no dosing or adverse event data are currently available on the use of EZN-2968 in patients <18 years of age, children are excluded from this study but will be eligible for future pediatric trials, if applicable.
Life expectancy of greater than 3 months.
ECOG performance status 0-2 (Karnofsky (Bullet)60%).
Patients must have normal organ and marrow function as defined below:
absolute neutrophil count (Bullet)1,500/mcL
platelets (Bullet)100,000/mcL
total bilirubin 1.5 X ULN
AST/ALT 2.5 X institutional ULN
creatinine less than or equal to 1.5 x upper limit of normal
OR
creatinine clearance (measured) greater than or equal to 60 mL/minute for patients with creatinine levels >1.5 times upper limit of normal
INR 1.4
PTT 40 seconds unless due to lupus anticoagulant
Urine protein should be screened by urine analysis for urine protein:creatinine (UPC) ratio. For UPC ratio >1, 24-hour urine protein should be obtained and the level should be <500 mg for patient enrollment.
The effects of EZN-2968 on the developing human fetus are unknown. For this reason, women of childbearing potential and men must agree to use adequate contraception (abstinence; female use of hormonal methods, or barrier methods of birth control; male use of a condom) prior to study entry, for the duration of study participation, and for 6 months after completion of study. Because there is a risk for adverse events in nursing infants secondary to treatment of the mother with EZN- 2968, breastfeeding should be discontinued while the patient is on this trial and for
30 days after completion of treatment on this trial. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
Ability to understand and the willingness to sign a written informed consent document.
Willingness to undergo tumor biopsies for research purposes.

You may not qualify if…

Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events to eligibility levels (by performance status and laboratory criteria outlined above) due to agents administered more than 4 weeks earlier. Patients may have received investigational agent(s) as part of a Phase 0 study (also referred to as an early Phase I study or pre-Phase I study where a sub-therapeutic dose of drug is administered) at the PI's discretion, up to 2 weeks prior to study entry.
Patients may not be receiving any other investigational agents.
Patients with active brain metastases will be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Patients whose brain metastatic disease status remains stable for (Bullet) 3 months after treatment of the brain metastases without steroids or antiseizure medications may be enrolled at the discretion of the principal investigator.
Patients requiring therapeutic anticoagulation.
Hypertension not controlled by medical therapy (hypertension defined as systolic blood pressure >150 mmHg or diastolic pressure > 90 mmHg despite optimal medical management).
History of allergic reactions attributed to compounds of similar chemical or biologic composition to EZN-2968.
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. A history of hepatitis is allowed if, following consultation with Liver Diseases Branch, it is felt to be clinically stable.
Pregnant women are excluded from this study because EZN-2968 has the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with EZN-2968, breastfeeding should be discontinued if the mother is treated with EZN-2968.
HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with EZN-2968.
Patients with surgical non-healing wounds. Patients with other non-healing wounds will be evaluated and included at the PI s discretion if considered minor.
