A Pilot Study to Investigate the Off Label Use of Vismodegib as an Adjuvant to Surgery for Basal Cell Carcinoma Tumors (BCC)

Inclusion Criteria:

- Study patients must have at least one BCC, > 5 mm, eligible for Mohs surgical
removal; patients with BCCs that have been treated before (recurrent BCCs, BCCs that
failed other chemotherapy) are eligible for this trial, if they meet size criteria

- No Eastern Cooperative Oncology Group (ECOG) or Karnofsky performance status will be
employed

- Normal hepatic function: aspartate aminotransferase (AST) and alanine
aminotransferase (ALT) =< 2 x the upper limit of normal (ULN)

- Normal renal function : normal serum creatinine defined as <= 2.5 mg/dL

- Clinically acceptable complete blood count (CBC)

- Ability to understand and the willingness to sign a written informed consent document

- The patient is willing to forego surgical treatment of BCCs by up to 6 months, except
when the principal investigator (PI) believes that delay in treatment potentially
might compromise the health of the subject

- Documented negative serum pregnancy test for women of childbearing potential, with
agreement to the use of two acceptable methods of contraception during the study and
for 7 months after discontinuation of vismodegib

- For men with female partners of childbearing potential, agreement to use a latex,
non-latex, or any other male condom and to advise their female partners to use an
additional acceptable method of birth control during the study and for 2 months after
discontinuation of study drug

- Be willing to not donate blood or semen for three months following discontinuation of
study medications

Exclusion Criteria:

- The patient has a history of invasive cancer within the past five years excluding
non-melanoma skin cancer, stage I cervical cancer, ductal carcinoma in situ of the
breast, or chronic lymphocytic leukemia (CLL) stage 0

- The subject has uncontrolled systemic disease, including known human immunodeficiency
virus (HIV) positive patients:

- The patient has history of congestive heart failure

- The patient has clinically important history of liver disease, including viral
or hepatitis, current alcohol abuse, or cirrhosis

- The patient has any condition or situation which in the investigator's opinion
may put the patient at significant risk, could confound the study results, or
could interfere significantly with the subject's participation in the study;
this includes history of other skin conditions or disease, metabolic
dysfunction, physical examination finding, or clinical laboratory finding giving
reasonable suspicion of a disease or condition that contraindicates use of an
investigational drug or that might affect interpretation of the results of the
study or render the patient at high risk from treatment complications

- The patient has a history of hypersensitivity to any of the ingredients in the study
medication formulations

- The patient is willing to abstain from application of non-study topical medications
to the skin for the duration of the study, including prescription and over the
counter preparations; for example, topical preparations containing corticosteroids or
vitamin A derivatives are not allowed

- Pregnant or nursing patients will be excluded from the study
