| Change From Baseline Scores of Skindex-16 Questionnaire Domains of Emotion, Function and Symptom | Baseline to the data cut-off date of 14 June 2017 (up to 6 years). | The Skindex-16 questionnaire includes three domains for the assessment of the effects of skin disease on participants' quality of life: symptoms, emotions and function. For each domain, responses from the questionnaire were transformed to a linear scale of 100 varying from 0 (never bothered, i.e., best) to 100 (always bothers, i.e., worst). |
| Best Overall Response Rate (BORR) | Baseline to the data cut-off of 14 June 2017 (up to 6 years) | BORR was defined as the percentage of participants achieving either a complete response (CR) or a partial response (PR) as assessed by the Investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. CR was defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) required a reduction in short axis to \<10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. |

For 13 items (i.e., pain, fatigue, nausea, disturbed sleep, distress, shortness of breath, difficulty remembering things, lack of appetite, drowsiness, dry mouth, sadness, vomiting, and numbness or tingling), participants were asked to rate how severe the symptoms were when at their worst in the last 24 hours. For the remaining 6 items, participants were asked to rate how much the symptoms have interfered with 6 areas of functioning (i.e., general activity, walking, work, mood, relations with other people, and enjoyment of life) in the last 24 hours. |

Percentage of Participants With a ≥ 30% Reduction in Composite Symptom Severity Score According to MDASI Scale
M.D. Anderson Symptom Inventory (MDASI) scale. The MDASI core instrument is a 19-item patient self-report questionnaire whose items comprise two scales, symptom severity and symptom interference. For 13 items (i.e., pain, fatigue, nausea, disturbed sleep, distress, shortness of breath, difficulty remembering things, lack of appetite, drowsiness, dry mouth, sadness, vomiting, and numbness or tingling), participants were asked to rate how severe the symptoms were when at their worst in the last 24 hours. For the remaining 6 items, participants were asked to rate how much the symptoms have interfered with 6 areas of functioning (i.e., general activity, walking, work, mood, relations with other people, and enjoyment of life) in the last 24 hours.
Time frame: 08-May-2013 (Protocol Version ≥ 4) to the data cut-off date of 14 June 2017 (approximately 4 years and 1 month).
Population: Included only participants who were enrolled after Protocol Version 4 was implemented, had non-missing data and average baseline score ≥ 4. Per protocol, the MDASI measurements were measured in Metastatic patients only.

M.D. Anderson Symptom Inventory (MDASI) scale. The MDASI core instrument is a 19-item patient self-report questionnaire whose items comprise two scales, symptom severity and symptom interference. For 13 items (i.e., pain, fatigue, nausea, disturbed sleep, distress, shortness of breath, difficulty remembering things, lack of appetite, drowsiness, dry mouth, sadness, vomiting, and numbness or tingling), participants were asked to rate how severe the symptoms were when at their worst in the last 24 hours. For the remaining 6 items, participants were asked to rate how much the symptoms have interfered with 6 areas of functioning (i.e., general activity, walking, work, mood, relations with other people, and enjoyment of life) in the last 24 hours.
Time frame: 08-May-2013 (Protocol Version ≥ 4) to the data cut-off date of 14 June 2017 (approximately 4 years and 1 month).
Population: Included only participants who were enrolled after Protocol Version 4 was implemented, had non-missing data and baseline score ≥4. Per protocol, the MDASI measurements were measured in Metastatic patients only.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Vismodegib - Locally Advanced | Percentage of Participants With a ≥ 30% Reduction in Disease-Related Symptoms According to MDASI Scale | 60.0 Percentage of participants |
Progression-Free Survival (PFS)
PFS was defined as the time interval between the date of the first therapy and the date of progression or death for any causes, whichever occurs first. Disease progression was assessed by the investigator.
Time frame: Baseline to the data cut-off of 14 June 2017 (up to 6 years)
Population: Only included participants that had histologically confirmed disease and measureable disease status at baseline (measureable or non-measureable).
| Arm | Measure | Value (MEDIAN) |
|---|---|---|
| Vismodegib - Locally Advanced | Progression-Free Survival (PFS) | 20.30 months |
| Vismodegib - Metastatic | Progression-Free Survival (PFS) | 12.85 months |
Time to Response
Time to response was defined as the interval between the date of first treatment and the date of first documentation of confirmed CR or PR (whichever occur first).
Time frame: Baseline to the data cut-off of 14 June 2017 (up to 6 years)
Population: Only included participants that had histologically confirmed measurable disease at baseline.
| Arm | Measure | Value (MEDIAN) |
|---|---|---|
| Vismodegib - Locally Advanced | Time to Response | 3.65 months |
| Vismodegib - Metastatic | Time to Response | NA months |
