Study of REOLYSIN® in Combination With Paclitaxel and Carboplatin in Patients With Metastatic Melanoma

Cutaneous melanoma is one of the most rapidly increasing cancers in the US and around the world with an increase in incidence of about 3-7% per year for fair-skinned Caucasian populations. An estimated 62,480 cases of invasive melanoma will be diagnosed in the US in 2008 with an estimated 8,420 deaths. An additional 46,170 cases of melanoma in situ are predicted.

Melanoma that has spread to distant sites (stage IV) is rarely curable.

This Phase 2 study is designed to characterize the efficacy and safety of REOLYSIN given intravenously in combination with paclitaxel and carboplatin every 3 weeks in patients with metastatic melanoma.

Response is a primary endpoint of this trial.

Patients may continue to receive chemotherapy in combination with REOLYSIN for up to 8 cycles and may continue indefinitely on REOLYSIN monotherapy under this protocol, provided they have not experienced either progressive disease or unacceptable drug-related toxicity that does not respond to either supportive care or dose reduction.

Inclusion criteria

• have histologically or cytologically confirmed metastatic malignant melanoma.
• have measurable disease.
• have failed at least one prior treatment for metastatic disease or not considered a candidate for standard first line treatment.
• have not received previous carboplatin and/or paclitaxel chemotherapy.
• have NO continuing acute toxic effects of any prior radiotherapy, chemotherapy, or surgical procedures.
• any surgery involving the melanoma (except biopsies) must have occurred at least 28 days prior to study enrolment.
• be at least 18 years of age.
• have received NO chemotherapy, radiotherapy, immunotherapy or hormonal therapy within 28 days prior to receiving study drug
• have ECOG Performance Score of ≤ 2.
• have a life expectancy of at least 3 months.
• absolute neutrophil ≥ 1.5 x 10^9; Platelets ≥ 100 x10^9; Hemoglobin ≥ 9.0 g/dL; Serum creatinine ≤ 1.5 x upper limit of normal (ULN); Bilirubin ≤ 1.5 x ULN; AST/ALT ≤ 2.5 x ULN.
• negative pregnancy test for females with childbearing potential.
• be willing and able to comply with scheduled visits, the treatment plan, and laboratory tests.

Exclusion criteria

• receive concurrent therapy with any other investigational anticancer agent while on study.
• be good candidate for surgery with curative intent for metastatic disease.
• have a history of or current evidence of brain metastasis(es).
• be on immunosuppressive therapy or have known HIV infection or active hepatitis B or C.
• be a pregnant or breast-feeding woman.
• have clinically significant cardiac disease.
• have dementia or altered mental status that would prohibit informed consent.
• have any other acute, or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration or may interfere with the interpretation of study results and, in the judgment of the Principal Investigator, would make the patient inappropriate for this study.
