Intralesional therapy with PV-10 (Rose Bengal) for in-transit melanoma

Rose Bengal is a novel injectable agent that has been evaluated as a rational treatment strategy for melanoma patients with recurrent unresectable local/regional metastases accessible for intralesional injection. PV-10 (10% Rose Bengal) has completed phase 1 and phase 2 multi-center clinical trials demonstrating significant local/regional disease control and also responses in non-injected regional bystander lesions and distant metastases. The published results of studies that have assessed PV-10 are presented, and the rationale for combining its use with recently approved immunotherapeutic agents is discussed.
