Brief Summary

LErafAON is a liposome encapsulated c-raf antisense oligonucleotide. Raf-1 is a protein produced by human cells, both normal and cancerous, which may help protect tumor cells from radiation. Antisense oligonucleotides are very specific drugs, which can decrease the amount of a certain target protein by blocking the gene that makes it. Antisense oligonucleotide to raf gene can reduce the amount of Raf-1 protein in tumor cells. Liposomes are tiny globules of fat, which can carry drugs in the body. The experimental agent LErafAON is composed of liposomes carrying antisense oligonucleotide against the Raf-1 protein. It is hoped that decreased Raf-1 in the cancer cells will make them more sensitive to the radiation therapy. Patients with advanced malignancies will receive daily IV infusions of LErafAON for 2 weeks (total of 10 doses) during clinically indicated palliative radiotherapy. Cohorts of at least three patients will be entered at escalating dose-levels. Each cohort will be observed for toxicity for at least two weeks after completion of treatment with study medication before the next cohort is enrolled. The study will be stopped when a maximum tolerated dose (MTD) is identified. Dose escalation within a patient will not be allowed. Safety and supportive care requirements will be assessed.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

-Disease Characteristics- Histologically-confirmed malignancy which has recurred or progressed after initial definitive treatment and/or for which no curative therapy is available. Palliative radiation therapy indicated for disease and site. (More than one lesion may be treated with radiation therapy.) At least 30 days must have elapsed since receiving an investigational agent, at least 21 days since receiving any prior chemotherapy or radiation, and at least six weeks since receiving nitrosourea-containing therapy; patient must have recovered from any related side effects. The site for radiotherapy, the index lesion, must have a measurable or evaluable tumor documented no more than 4 weeks prior to having study-related procedures. More than one lesion may be present and treated with radiotherapy. Additional lesions, not treated with radiotherapy, may also be present. Previously irradiated sites will NOT be irradiated in this study. -Patient Characteristics- Performance Status (ECOG/ZUBROD) of 0-2. Must be at least 18 years of age. Must have adequate organ function: Absolute neutrophil count at least 1,500/mm3; Platelets at least 100,000/mm3; Creatinine, Calcium, and total Bilirubin not higher than the upper limit of normal; Liver enzymes AST and ALT not more than 2.5 x the upper limit of normal; PT and aPTT not more than the upper limit of normal. Life expectancy more than 12 weeks. Must sign Informed Consent. Planned treatment site(s) has not had previous radiation therapy. Patients must not have concurrent antitumor therapy other than that planned in the study. No history of Grade 4 toxicity from prior radiation therapy. (Grade 3 toxicity from prior radiation therapy, at investigator discretion.) No infection requiring parenteral antibiotics; no HIV infection; no chronic hepatic disease; and no seropositivity for Hepatitis B and Hepatitis C. (Use of prophylactic antibiotics is permitted.) No pregnant or lactating females. All females of child-bearing potential must use an effective method of contraception. No active central nervous system (CNS) metastasis. Neuroimaging is required only if metastasis is suggested by history or physical examination.
