PRIMARY outcome

Timeframe: Baseline, Week 12

Population: Participants who received at least 1 dose of study drug who had evaluable GLI1 mRNA data at Baseline and Week 12.

GLI1 change is a biomarker of the HH signaling pathway. A change in GLI1 mRNA levels reflect a change in the HH pathway. Surgically eligible basal cell carcinomas (SEBs) were defined as clinically diagnosed basal cell carcinoma (BCC) 5 to 20 millimeters (mm) in diameter on the face, excluding the nose and periorbital skin, and 9 to 20 mm at sites other than the face. A single baseline BCC designated as a treatment-targeted tumor at Baseline was biopsied first at Baseline and again following 12 weeks of treatment. This was used to assess percent change in GLI1 mRNA levels as follows: (Baseline - Week 12) / Baseline \* 100, with positive numbers to represent increases and negative numbers to represent decreases. Any missing values were not imputed; all available data is summarized.

SECONDARY outcome

Timeframe: Baseline, Week 12

Population: Participants who received at least 1 dose of study drug.

SEBs were defined as clinically diagnosed BCC 5 to 20 mm in diameter on the face, excluding the nose and periorbital skin, and 9 to 20 mm at sites other than the face. The percent change in greatest diameters of treatment-targeted surgically eligible basal cell carcinomas (SEBs) from Baseline to Week 12 was calculated as follows: (sum \[Baseline\] - sum \[Week 12\] / sum \[Baseline\] \* 100), where sum = the greatest diameters of treatment-targeted SEBs and positive numbers to represent increases and negative numbers to represent decreases. Missing values were imputed using Last-Observation Carried Forward (LOCF).

SECONDARY outcome

Timeframe: Baseline, Week 12

Population: Participants who received at least 1 dose of study drug.

SEBs were defined as clinically diagnosed BCC 5 to 20 mm in diameter on the face, excluding the nose and periorbital skin, and 9 to 20 mm at sites other than the face. The percentage of tumors showing a complete or partial response at Week 12 was calculated as follows: (Number of baseline treatment-targeted SEBs showing complete or partial response at Week 12) / (Number of Baseline treatment-targeted SEBs) \* 100. Missing values were not imputed.Complete Response is determined when there is no longer any visible evidence of a lesion consistent with BCC at the site, and Partial Response is determined when although a BCC still remains at this site, it has demonstrated a visible decrease in size compared with baseline.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline and Weeks 2, 6, 8, 10, and 12

Population: Participants who received at least 1 dose of study drug.

The ISGTA is a scale with scores ranging from 0 (clear), 1 (almost clear), 2 (minimal residual tumor), to 3 (clearly visible tumor). The Investigator assessed each Baseline treatment-targeted SEB at Weeks 2, 6, 8, 10, and 12. SEBs were defined as clinically diagnosed BCC 5 to 20 mm in diameter on the face, excluding the nose and periorbital skin, and 9 to 20 mm at sites other than the face. The percentage of Baseline treatment-targeted SEBs evaluated as being clear or almost clear at Week x (Week x = 2, 6, 8, 10, or 12) based on the ISGTA scale was calculated as follows: (Number of baseline treatment-targeted SEBs with ISGTA score of 0 or 1 at Week x) / (Number of Baseline treatment-targeted SEBs) \* 100. Missing data were imputed using LOCF. The percentage of responders achieving clear (0) or almost clear (1) on the ISGTA scale are presented by Week.

POST_HOC outcome

Timeframe: Week 12

Population: Participants who received at least 1 dose of study drug.

The ISGTA is a scale with scores ranging from 0 (clear), 1 (almost clear), 2 (minimal residual tumor), to 3 (clearly visible tumor). The Investigator assessed each Baseline treatment-targeted SEB at Week 12. SEBs were defined as clinically diagnosed BCC 5 to 20 mm in diameter on the face, excluding the nose and periorbital skin, and 9 to 20 mm at sites other than the face. The percentage of Baseline treatment-targeted SEBs evaluated as being clear at Week 12 based on the ISGTA scale and BCC not present was calculated as follows: (Number of baseline treatment-targeted SEBs with ISGTA score of 0 and BCC not present at Week 12) / (Number of Baseline treatment-targeted SEBs) \* 100.
