  Purpose

This randomized, double-blind, regimen-controlled, phase II, multicenter study w ill assess the efficacy and safety of two different vismodegib regimens in patie nts with multiple basal cell carcinoma. Patients will receive vismodegib 150 mg orally once daily either in an intermittent schedule of 12 weeks vismodegib foll owed by 8 weeks placebo (Arm A) or as 24 weeks induction followed by an intermit tent schedule of 8 weeks placebo followed by 8 weeks vismodegib (Arm B). Anticip ated time on study treatment is 72 weeks.

Primary Outcome Measures:
  • Relative reduction (%) from baseline in the number of clinically evident basal cell carcinomas at Week 73 (after 72 weeks of treatment) [ Time Frame: from baseline to Week 73 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Drop-out rate: Discontinuation of study treatment prior to Week 73 for either adverse events or withdrawal of consent by the patient [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Relative reduction (%) from baseline in total size of three target basal cell carcinoma lesions in individual patients at Week 73 [ Time Frame: from baseline to Week 73 ] [ Designated as safety issue: No ]
  • Proportion of patients with at least 50% reduction in the number of basal cell carcinomas at Week 73 in the two treatment regimens [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Number of new basal cell carcinomas at Week 73 in the two treatment groups [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Recurrence rate up to Week 125 (52 weeks after study drug discontinuation) [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Patient reported outcomes: Skindex-16 tool [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Adult patients, >/= 18 years of age
  • Patients with multiple basal cell carcinomas, including patients with Gorlin syndrome, with at least 6 clinically evident basal cell carcinomas at the time of randomization, of which 3 measure 5 mm or more in diameter and are considered target lesions. All other lesions are considered to be non-target lesions

  • Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2
  • Adequate renal and hepatic function and hematopoietic capacity
  • Women of childbearing potential must agree to use contraception as defined by protocol during treatment and for at least 7 months after completion of study treatment
  • Male patients with female partners of childbearing potential must agree to use contraception as defined by protocol during treatment and for 2 months after completion of study treatment

Exclusion Criteria:

  • Inability or unwillingness to swallow capsules
  • Pregnant or breastfeeding women
  • Any metastatic basal cell carcinoma
  • Locally advanced basal cell carcinoma lesion that is considered to be inoperable or to have medical contraindications to surgery
  • Recent (.i.e. within the past 28 days prior to randomization) or current participation in another experimental drug study
  • Known or suspected alcohol abuse
  • One of the following known rare hereditary conditions: galactose intolerance, primary hypolactasia or glucose-galactose malabsorption
