3+3 design. Specifically, in each dose group n=3 participants were treated. If no DLTs were observed, the study was escalated to the next dose level. If DLTs had been observed in 2 or more participants, then the MTD would have been exceeded. If one DLT had been observed, an additional three participants would have been added at the same dose level. If no DLTs had been observed in the additional three participants, the study would have escalated to the next dose level. If DLTs had been observed in one or more of the three additional participants, the MTD would have been exceeded. The first two dose groups, Placebo and 25 µg, screened and enrolled subjects concurrently in the study.

SkinJect hypothesized that treatment with D-MNA would result in tumor destruction and the induction of potent, immunogenic anti-tumor responses. Because MNAs enable this agent to be delivered at very low doses to a confined tumor microenvironment, the study sponsor expected only minimal, if any, systemic drug toxicity; thus, facilitating optimal local dose levels and durable clinical responses.

The study design also included a placebo group (placebo-MNA). Inclusion of placebo-MNA allowed the evaluation of two questions:

In addition the clinical design also assessed the pre-established secondary efficacy endpoint described below.

Subject populations included adult males and females, 18+ years in general good health as assessed by the study's principal investigator. BCC (subtype: superficial or nodular) had to confirmed histologically by diagnostic shave biopsy at the screening visit. If previously confirmed, participants could only have diagnosed BCC via shave biopsy within 6 months of first study treatment. The disease had to be primary BCC (i.e., no previous treatment), and the lesion size was required to = 64 mm2 or 8 x 8 mm and = 169 mm2 or 13 x 13 mm, i.e., the entire lesion must be covered by 13 x 13 mm area of the array containing the microneedles. Laboratory values had to be within normal ranges.

Subjects were excluded from participation in this study if they had evidence of clinically significant, unstable medical conditions as assessed by the principal investigator; if they had an excisional biopsy performed on the lesion to be treated in this study; if they had recent therapy(ies) to the BCC treatment area; if they had recurrent BCC (previously treated) at the site
