Primary Outcome Measures :
  1. Number of Participants With Adverse Events [ Time Frame: 6 weeks ]
    To determine the safety and tolerability of API 31510 cream 3%, topically applied to in situ cutaneous squamous cell carcinomas (SCCIS).

Secondary Outcome Measures :
  1. Percentage of Participants With a Complete Response [ Time Frame: 6 weeks ]

    To obtain a preliminary determination of the efficacy of API 31510 cream 3%,topically applied to in situ cutaneous squamous cell carcinomas.

    The subject was considered to have had a complete response only if the histological examination of the target lesion was negative.
