Study Description

Brief Summary:

The objective of this study is to investigate the safety of intralesional (IL) PV-10 for the treatment of metastatic melanoma. This study will also include a preliminary assessment of response of treated and untreated lesions by clinical evaluation at follow-up of 12 to 24 weeks following IL PV-10 treatment.

Condition or disease	Intervention/treatment	Phase
Melanoma	Drug: PV-10 (rose bengal disodium, 10%)	Phase 1

Detailed Description:

This is a two center, open label, ascending dose study. Subjects with at least two measurable melanoma lesions will receive a single intralesional injection of 10% PV-10 solution into each of one to twenty (20) target lesions. Additionally, one to three measurable untreated non-target lesions will be followed for assessment of bystander response. Systemic and locoregional adverse events will be monitored over the study interval. Dose escalation will be made only if no subjects at the first dose level have a Grade 3 non-hematological or Grade 4 hematological toxicity over a period of two weeks after PV-10 administration. Subject accrual and PV-10 administration at the second dose level will be stopped if more than 1 subject has a treatment related Grade 3 non-hematological or Grade 4 hematological toxicity within a period of two weeks after PV-10 administration.

Criteria

Inclusion Criteria:
