Brief Summary:
This randomized, double-blind, regimen-controlled, phase II, multicenter study will assess the efficacy and safety of two different vismodegib regimens in participants with multiple basal cell carcinoma. Participants will receive vismodegib 150 mg orally once daily either in an intermittent schedule of 12 weeks vismodegib followed by 8 weeks placebo (Arm A) or as 24 weeks induction followed by an intermittent schedule of 8 weeks placebo followed by 8 weeks vismodegib (Arm B). Anticipated time on study treatment is 72 weeks.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Mean Percent Change From Baseline in the Number of Clinically Evident Basal Cell Carcinomas at Week 73 (After 72 Weeks of Treatment) [ Time Frame: Baseline; Week 73 ]
    The total number of clinically evident basal cell carcinomas = the total number of target and/or non-target lesions present in individual participants.


Secondary Outcome Measures :
  1. Percentage of Participants Who Discontinued Study Treatment Due to Tolerability Issues [ Time Frame: Baseline to Week 73 ]
    The percentage of participants who discontinued study treatment (due either to adverse event, refusal of treatment, or withdrawal of consent) was summarized by treatment group.

  2. Mean Percent Change From Baseline in Total Size of Three Target Basal Cell Carcinoma Lesions in Individual Participants at Week 73 [ Time Frame: Baseline; Week 73 ]
    The three target basal cell carcinoma lesions = the three largest visible lesions, at least 5 mm in the longest diameter, in individual participants.

  3. Percentage of Participants With at Least 50% Reduction in the Number of Basal Cell Carcinomas at Week 73 [ Time Frame: Baseline; Week 73 ]
  4. Percentage of Participants With New Basal Cell Carcinomas at Week 73 [ Time Frame: Baseline; Week 73 ]
  5. Percent Change in Total Number of Basal Cell Carcinomas Relative to Baseline at Week 85 (12 Weeks Following End of Treatment) (Recurrence Rate) [ Time Frame: Baseline; Week 85 ]
  6. Percent Change in Total Number of Basal Cell Carcinomas Relative to Baseline at Week 97 (24 Weeks Following End of Treatment) (Recurrence Rate) [ Time Frame: Baseline; Week 97 ]
  7. Percent Change in Total Number of Basal Cell Carcinomas Relative to Baseline at Week 125 (52 Weeks Following End of Treatment) (Recurrence Rate) [ Time Frame: Baseline; Week 125 ]
  8. Percentage of Participants Experiencing Any Adverse Event [ Time Frame: Up to 125 weeks ]
  9. Percent Change From Baseline in the Skindex-16 Symptom Domain Score at Week 73 [ Time Frame: Baseline; Week 73 ]
    The Skindex-16 is a patient-reported outcome health questionnaire. Participants were asked about their symptoms, and their answers were combined into a composite Symptom Domain Score. Scores range from 0 ("never bothered") to 100 ("always bothered").

  10. Percent Change From Baseline in the Skindex-16 Emotion Domain Score at Week 73 [ Time Frame: Baseline; Week 73 ]
    The Skindex-16 is a patient-reported outcome health questionnaire. Participants were asked about their emotional state, and their answers were combined into a composite Emotion Domain Score. Scores range from 0 ("never bothered") to 100 ("always bothered").

  11. Percent Change From Baseline in the Skindex-16 Function Domain Score at Week 73 [ Time Frame: Baseline; Week 73 ]
    The Skindex-16 is a patient-reported outcome health questionnaire. Participants were asked about their ability to function, and answers were combined into a composite Function Domain Score. Scores range from 0 ("never bothered") to 100 ("always bothered").

Criteria

Inclusion Criteria:

  • Adult participants, >/= 18 years of age
  • Participants with multiple basal cell carcinomas, including participants 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.

  • 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
