  Purpose

The primary objectives of this study are to assess, using Mohs micrographic surgery (MMS) at the end of treatment, the efficacy (primary) and safety (secondary) of vismodegib compared to placebo in the oral adjunctive pre surgical treatment of basal cell carcinoma. A secondary objective is to assess how often and in what types of lesions does pre surgical treatment with vismodegib result in complete eradication of the tumor.

Further study details as provided by Loma Linda University:

Primary Outcome Measures:
  • Mohs Micrographic Surgery (MMS) [ Time Frame: The Mohs surgical excision of the target tumor was performed within two weeks, after the last day of treatment. ] [ Designated as safety issue: No ]
    The final wound size taken immediately after the completion of Mohs surgery (i.e., upon reaching tumor-free tissue margins) was determined using pre treatment lesion outlined plus one additional concentric 2mm margin removed to establish an objective consistent measure for wound size. The diameter of the final wound size was measured in mm.


Secondary Outcome Measures:
  • Complete Response Rate [ Time Frame: 12 to 14 weeks ] [ Designated as safety issue: No ]
    A secondary variable is the complete response rate, defined as the proportion of patients with no histological evidence of basal cell carcinoma on the post treatment MMS excision of the target tumor area. For this analysis, the placebo data will be pooled together to calculate the complete response rate for the placebo group.

Criteria

Inclusion Criteria:

  1. Willing and able to give informed consent.
  2. At least 18 years of age.
  3. Have a confirmed BCC at one of listed anatomical sites which must be biopsy-confirmed at the study site and meets this criteria:

    • non-infected
    • minimum tumor area of 0.5 cm2 in an anatomic location at risk for significant deformity or functional impairment with surgery.
    • macroscopically (clinically) consistent with BCC
    • histologically consistent with BCC
    • suitable for treatment with Mohs surgical excision
    • identifiable by subject or reliable subject representative
  4. Free of any significant physical abnormalities (e.g., tattoos) at treatment site.
  5. Willing and able to participate in the study as an outpatient, making frequent visits to clinic during treatment and follow-up periods and comply with study requirements, including:

    • Consenting to biopsy of the lesion at baseline, if needed, before beginning study drug treatment
    • Attend all scheduled clinic visits during pre-study, treatment, and follow-up periods
    • Will delay excision of the target tumor site until time mandated in the protocol, unless evidence of disease progression or lack of drug tolerability
    • Post-excisional follow-up visits until the area is healed to investigator's satisfaction
  6. Female of reproductive potential must use 2 forms of acceptable contraception (including one acceptable barrier method with spermicide) during therapy and for 7 months after completing therapy.
  7. Male patients must use condoms at all times, with spermicide, even after vasectomy, during sexual intercourse with females during treatment and for 2 months after the last dose.
  8. Agrees not to donate blood or blood products during the study and for 7 months after last dose.

Exclusion Criteria:

  1. Prior treatment with GDC-0449 or any HH Pathway Inhibitor

Subjects with clinically stable medical conditions including, but not limited to, controlled hypertension, diabetes mellitus type II, hypercholesterolemia, or osteoarthritis, will be allowed to enter the study.
  3. Have any dermatological disease at treatment site that may be exacerbated by treatment with vismodegib or cause difficulty with examination (e.g., psoriasis, eczema).
  4. Inability or unwillingness to swallow capsules
