 a subsequent Phase 2 study. Of the 13 subjects enrolled, all 13 subjects completed the study and were included in all analysis populations; no subjects discontinued the study prematurely. Most subjects (8 of 13) were male, all subjects were White, and all but one subject were Non-Hispanic/Latino. Age range across the 13 subjects was 31 to 94 years.

The primary study endpoint was the assessment of DLT through Visit 4 (21 days) as defined using the LSR grading scale. No subjects reached DLT at any treatment assessment.

At screening, both the site and central reader were in agreement for 7 of 13 subjects (5 were considered nodular and 2 superficial at screening); however, for 6 subjects, the site and central reader assessments differed. For one subject (01-014), the Central Reader found no BCC present in the screening biopsy. Consultants reviewing the study results stated that multiple reasons could possibly be attributable, including human error misreading at the site, confusion of BCC with certain benign follicular tumors, and the presence of BCCs with both nodular and superficial components.

At the end of study, three subjects (01-001, Placebo; 01-008, D-MNA 25 µg and 01-011, D-MNA 50 µg) had differing results when Local/Site evaluation were compared to the Central Reader evaluation. In all three subjects, the Local/Site evaluation noted the presence of residual BCC compared to the Central Reader results which noted no residual BCC for all three subjects. It should be noted that the central reader was blinded to study treatment. In addition, another contributing factor to the noted differences may have been related to different slices of the tumor being evaluated by each of the readers; the local/site reader had the tissue sample obtained at the time of the excision, whereas the Central Reader tissue samples were sliced from the same block for each subject and stained several months later; the slides used in the Local/Site evaluation were not available for reading by the Central Reader.

For the secondary endpoint of BCC clinical response, evaluations were performed both at the local/site level as well as independently by a central reader. For the local/site assessment, complete lesion response was observed in one subject each for Placebo, D-MNA 25 µg, D-MNA 100 µg, and D-MNA 200 µg. For D-MNA 50 µg, no subjects were observed to
