Status
TERMINATED
Sex
All
Target Recruitment
18
Inclusion Criteria
  • Diagnosis of non-infected, not recurrent, previously untreated basal cell carcinoma
  • Free of any significant physical abnormalities (e.g., tattoos) at the target basal cell carcinoma site
  • Willing and able to participate in the study as an outpatient and agreement to make frequent visits to the clinic during the treatment and follow-up periods and to comply with study requirements
Exclusion Criteria
  • Prior treatment with vismodegib
  • Known hypersensitivity to any of the study drug excipients
  • Any metastatic basal cell carcinoma
  • Any locally advanced basal cell carcinoma considered to be inoperable or to have a medical contraindication to surgery
  • Evidence of clinically significant and unstable diseases or conditions (e.g., cardiovascular, immunosuppressive, hematologic)
  • Any dermatological disease at the target basal cell carcinoma site that may cause difficulty with examination
  • Recent, current, or planned participation in another experimental drug study

Primary Outcome Measures
NameTimeMethod
Percent Change in Target Basal Cell Carcinoma (BCC) Expected Surgical Defect Area at Mohs Micrographic Surgery (MMS) VisitBaseline, MMS visit (Week 12-14)

The percent change in target BCC expected surgical defect area was defined as (\[baseline expected surgical defect area - expected surgical defect area at MMS visit\]/ baseline expected surgical defect area) × 100 percent (%) where expected surgical defect area was manually outlined on a digital photograph and measured by a computer (computer aided planimetry). MMS visit was defined as the visit that occurred within 2 weeks of the last study treatment.

Secondary Outcome Measures
NameTimeMethod
Actual Change in Target BCC Expected Surgical Defect Area at MMS VisitBaseline, MSS Visit (Week 12-14)

Actual change was defined as (baseline expected surgical defect area - expected surgical defect area at MMS visit). MMS visit was defined as the visit that occurred within 2 weeks of the last study treatment. Expected surgical defect area was manually outlined on a digital photograph and measured by a computer (computer aided planimetry).

Percentage Change in Target BCC Actual Tumor-Free Margin Excision Area at MMS VisitBaseline, MMS visit (Week 12-14)

Percent change in target BCC actual tumor-free margin excision area was defined as = (expected surgical defect area pre-treatment - actual tumor-free margin excision area at MMS visit) / expected surgical defect area pre-treatment) \* 100%. The actual tumor-free margin excision area (includes 2 millimeters \[mm\] margin) was measured during MMS. The area was photographed and traced on the digital photograph then calculated by computer-aided planimetry. MMS visit was defined as the visit that occurred within 2 weeks of the last study treatment.

Percentage of Participants With Clinical ResponseMMS visit (Week 12-14)

Clinical response was defined as a complete response (CR) or partial response (PR) at the post-treatment MMS excision. CR was defined as no histological evidence of BCC. PR was defined as a reduction of at least 50 % in the expected surgical defect area with histologic evidence of residual BCC. MMS visit was defined the visit that occurred within 2 weeks of the last study treatment.

Percentage of Participants With BCC RecurrenceBaseline, 12, 24, and 52 weeks post MMS Visit (MMS Visit = Week 12-14)
Percentage of Participants With Skip AreaMMS visit (Week 12-14)

Skip area was defined as the presence of non-contiguous residual tumor at the MMS visit, as determined by an independent dermatopathologist. MMS visit occurred within 2 weeks of the last study treatment.
