Participant flow
Recruitment details
This was an open-label study with no randomization. Participants were categorized according to their baseline renal and hepatic function, and assigned to one of the five cohorts.
Pre-assignment details
After assessing the additional data since the study initiation and after discussions with regulators, the sponsor concluded that renal impairment does not impact the pharmacokinetics of vismodegib and, therefore, a dedicated renal impairment cohort was eliminated.

Outcome results
Maximum Observed Plasma Concentration and Concentration at Steady-state Following Multiple Doses of Vismodegib
Maximum observed plasma Concentration (Cmax) & Concentration at steady-state (Css) following multiple doses of vismodegib (150 mg QD) were analyzed.
