The purpose of this research study is to find out whether JX-594 is safe and effective for treating surgically unresectable malignant melanoma.
Cancer of the skin is the most common of all cancers, probably accounting for more than 50% of all cancers. Melanoma accounts for about 4% of skin cancer cases but causes a large majority of skin cancer deaths. The American Cancer Society estimates that about 62,190 new melanomas will be diagnosed in the United States during 2006.
DTIC is the only chemotherapy drug approved by the FDA for the treatment of metastatic melanoma. The reported response rates are 5-20% without any evidence of prolonged survival in randomized clinical trials versus best supportive care. The median overall survival for melanoma patients treated with DTIC alone is approximately 8 months; PFS and TTP following treatment with DTIC is approximately 7 weeks, and the objective response rate for DTIC alone (CR+PR) is less than 10% (Millward, 2004). Other chemotherapy agents including cisplatin and carboplatin, BCNU, vindesine, paclitaxel, docetaxel, and vinorelbine have also been tested but none have improved upon the very modest activity of DTIC.
Melanoma may be the optimal target for JX-594 immunotherapy because of the relatively high rate of accessible disease for injection, the positive response of melanoma seen with IL-2 immunotherapy, and the lack of effective, tolerable therapy for patient with metastatic melanoma. Furthermore, it is speculated that JX-594 replication targets the EGFR pathway, which is highly expressed in melanocytes.
Results from an initial Phase I/II study suggest that intratumoral injection of JX-594 is safe and effective in treating both injected and distant disease in patients with surgically incurable metastatic melanoma. Response of both injected tumors (in 5 of 7 patients) and response of at least one non-injected tumor (in 4 of 7 patients) was demonstrated, including two patients who achieved a partial response (6 + months) and a complete response (4 + months) to JX-594 treatment. Particularly noteworthy is that efficacy and gene expression occurred despite pre-treatment vaccination (and, therefore, pre-existing anti-vaccinia immunity) in all patients.

An unpigmented malignant melanoma. It is an anaplastic melanoma consisting of cells derived from melanoblasts but not forming melanin. (Dorland, 27th ed; Stedman, 25th ed)
Experimentally induced tumor that produces MELANIN in animals to provide a model for studying human MELANOMA.
A cellular subtype of malignant melanoma. It is a pigmented lesion composed of melanocytes occurring on sun-exposed skin, usually the face and neck. The melanocytes are commonly multinucleated with a "starburst" appearance. It is considered by many to be the in situ phase of lentigo maligna melanoma.
Found in large amounts in the plasma and urine of patients with malignant melanoma. It is therefore used in the diagnosis of melanoma and for the detection of postoperative metastases. Cysteinyldopa is believed to be formed by the rapid enzymatic hydrolysis of 5-S-glutathionedopa found in melanin-producing cells.
A melanosome-specific protein that plays a role in the expression, stability, trafficking, and processing of GP100 MELANOMA ANTIGEN, which is critical to the formation of Stage II MELANOSOMES. The protein is used as an antigen marker for MELANOMA cells.
There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma and malignant melanoma. Basal cell carcinoma Basal cell carcinoma, or BCC, is a cancer of the basal cells at the bottom of the epidermis. It’s very common ...
