• 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

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
