Patients received vismodegib 150 mg orally once daily until radiographically confirmed disease progression, intolerable toxicity, or withdrawal from the study.

Patients received placebo to vismodegib orally once daily until radiographically confirmed disease progression, intolerable toxicity, or withdrawal from the study.

Vismodegib 150 mg was provided in hard gelatin capsules.

Vismodegib 150 mg

Placebo to vismodegib consisted of the excipients for vismodegib without the active molecule in hard gelatin capsules matching the active drug product in color and size.

The study was a Phase II, randomized, placebo-controlled, double-blind, multicenter clinical trial of vismodegib (GDC-0449) in patients with ovarian cancer in a second or third complete remission. Patients were randomized in a 1:1 ratio to either vismodegib or placebo. Randomization was stratified based on whether their cancer was in a second or third complete remission.

A Phase II, Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial Evaluating the Efficacy and Safety of Vismodegib (GDC-0449) As Maintenance Therapy in Patients With Ovarian Cancer in a Second or Third Complete Remission

PFS was defined as the time between randomization and disease progression, as confirmed by radiography, or death for any reason. Since patients were in remission at the start of the study, they had no evidence of the presence of tumors. Disease progression was defined as radiographic evidence of a tumor. Tumor assessments by computed tomography (CT) of the chest, abdomen, and pelvis were performed at screening and every 8 weeks during the study.

Hedgehog antigen expression was measured with immunohistochemical methods in tumor tissue taken from each patient prior to enrollment in the study. The percentage of cells with (\> 0%) and without (0%) Hedgehog antigen expression was measured microscopically. PFS was defined as the time between randomization and disease progression, as confirmed by radiography, or death for any reason. Tumor assessments by computed tomography (CT) of the chest, abdomen, and pelvis were performed at screening and every 8 weeks during the study.

Overall survival was defined as the time from randomization until death by any cause.
