简要总结
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.

入选标准
- •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. All other lesions are considered to be non-target lesions
- •Histopathologic confirmation that at least one of the three target lesions is basal cell carcinoma
- •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 9 months after completion of study treatment
- •Male participants 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
排除标准
- •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
