Brief Summary:

The aim of the study is to compare the safety and effectiveness of a new drug called PI-88, when used in combination with an approved chemotherapy drug called dacarbazine, in the treatment of metastatic melanoma.

PI-88 blocks new blood vessel growth in tumours (starves it of nutrients) and dacarbazine stops the cancer cells from growing. The results from this study will be analysed to see if it is worthwhile for the two drugs to be tested in future studies involving larger numbers of melanoma patients.

Condition or disease Intervention/treatment Phase
Melanoma Drug: PI-88 and dacarbazine Drug: dacarbazine or DTIC Phase 2

Detailed Description:
Metastatic melanoma is a difficult-to-treat cancer for which available treatment options are limited and minimally effective. Dacarbazine is currently one of the standard chemotherapy drugs used for the treatment of metastatic melanoma. However, it is associated with low response rates (10-20%) and median survival of less than 12 months (6-11 months in most studies). PI-88 is an antiangiogenic and antimetastatic drug that has already shown some evidence of efficacy when used alone in an intermittent dosage regimen (4 consecutive days per week) in the treatment of patients with advanced melanoma. The FDA has designated PI-88 as an Orphan Drug for this indication, as well as for Stage III and high-risk stage II disease. The aim of this randomised pilot phase II trial is to determine whether PI-88 in combination with a standard regimen of dacarbazine (1000 mg/m2 every 3 weeks) should be considered for further investigation in a larger-scale trial.
