Reporting Groups
  Description
PV-10 PV-10 (10% rose bengal disodium): Intralesional injection for chemoablation. In the treatment phase, participants received a single IL injection of PV-10 into each of up to 20 study lesions on day 0 (i.e., one cycle). Treatment cycles could be repeated at weeks 8, 12 and 16 for new non-target lesions or existing target or non-target lesions not exhibiting complete response (i.e., complete disappearance). Participants were observed for 52 weeks. Radiologic assessments of visceral disease status were performed every 12 weeks throughout the study and patients were transitioned into survival follow-up if at any time the investigator identified clinical or radiologic evidence of distant progression. No other melanoma therapy was permitted during the study interval.

[1] Participants were staged clinically at baseline based on cutaneous and subcutaneous, nodal and visceral tumor burden. Stage III participants had disease confined to cutaneous, subcutaneous and/or nodal sites. Stage IV participants had distant metastatic disease (i.e., distant cutaneous or subcutaneous metastases or visceral metastases).

Participants were staged clinically at baseline using the ECOG Performance Status scale:

GRADE 0: Fully active, able to carry on all pre-disease performance without restriction. GRADE 1: Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, e.g., light house work, office work. GRADEe 2: Ambulatory and capable of all selfcare but unable to carry out any work activities; up and about more than 50% of waking hours.

All Lesions Treated Except Bystanders   26 
All Lesions Treated   28 
[1] Participants were categorized at baseline according to tumor burden that was not injected with PV-10.
