What was measured

PFS was defined as the time from start of treatment to the earliest documented disease progression (PD) or death. Metastatic BCC - PD: ≥ 20% increased sum of the longest diameter (SLD) of targets from nadir, or 1 or more new lesions. Locally advanced BCC - PD: any of: (1) ≥ 20% increased SLD from nadir (radiography or externally visible dimension); (2) new ulceration; (3) new lesions (radiography or physical exam); (4) progression of non-target lesions by radiography.

Analysis population: Efficacy-evaluable population: All treated patients for whom the independent pathologist's interpretation of archival tissue or baseline biopsies was consistent with basal cell carcinoma.

Groups in this outcome

Metastatic Basal-Cell Carcinoma

Patients received vismodegib 150 mg orally once daily until disease progression; intolerable toxicity, most probably attributable to vismodegib; or withdrawal from the study.

Locally Advanced Basal-Cell Carcinoma

Patients received vismodegib 150 mg orally once daily until disease progression; intolerable toxicity, most probably attributable to vismodegib; or withdrawal from the study.
