Low dose continuous chemotherapy, called metronomic chemotherapy, is designed to target vascular cells and inhibit tumor growth and metastasises. A recent study in a melanoma mouse model has identified low dose vinblastine, cyclophosphamide and dacarbazine as a treatment which improves the animal's survival and is superior to full dose dacarbazine alone. This clinical trial seeks to translate this laboratory model directly into metastatic melanoma patients.
