The purpose of this study is to determine the safety and tolerability of pharmaceutical compound (API 31510) topical cream topically applied to superficial basal cell carcinomas to obtain preliminary efficacy data for the treatment of superficial basal cell carcinomas by API 31510 topical cream. The study population will include one hundred and sixty (160) otherwise healthy male or female adults with one or more histologically confirmed superficial basal cell carcinoma lesions. One target lesion with an area of less than one inch will be designated for study treatment.

Histological diagnosis made no more than 4 weeks prior to the screening visit
Histological biopsy removed 25% or less of the target lesion
No other dermatological disease in the sBCC target site or surrounding area
Willing to refrain from using non-approved lotions or creams on the target site and surrounding area during the treatment period. Willing to refrain from washing the treated area for at least 8 hours following the application of study medication
Willing to refrain from exposure to direct sunlight or ultraviolet light and to avoid the use of tanning parlors for the duration of the study

Ability to follow study instructions and likely to complete all study requirements
Written informed consent obtained, including consent for tissue to be examined and stored by the central dermatopathologist
Written consent to allow photographs of the target sBCC lesion to be used as part of the study data

Concurrent disease or treatment that suppresses the immune system
Chronic medical condition that in the judgment of the investigator(s) would interfere with the performance of the study or would place the patient at undue risk

Undergone a facial resurfacing procedure, i.e., chemical peel, laser resurfacing, dermabrasion, within the 6 months prior to the screening visit, if the target sBCC lesion is on the face
