About this study
Official title: A Randomized, Double-blinded, Regimen-controlled, Phase II, Multicenter Study to Assess the Efficacy and Safety of Two Different Vismodegib Regimens in Patients With Multiple Basal Cell Carcinomas
This randomized, double-blind, regimen-controlled, phase II, multicenter study will assess the efficacy and safety of two different vismodegib regimens in participants with multiple basal cell carcinoma. Participants will receive vismodegib 150 mg orally once daily either in an intermittent schedule of 12 weeks vismodegib followed by 8 weeks placebo (Arm A) or as 24 weeks induction followed by an intermittent schedule of 8 weeks placebo followed by 8 weeks vismodegib (Arm B). Anticipated time on study treatment is 72 weeks.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
VismodegibDrug
Also called Erivedge®
Vismodegib 150 mg hard gelatin capsule orally once daily
PlaceboDrug
Vismodegib placebo orally once daily
| Study group | Role | What they receive |
|---|---|---|
| Vismodegib Intermittent Schedule | Experimental | Vismodegib intermittent schedule of 12 weeks vismodegib followed by 8 weeks placebo, repeated 3 times with a final course of vismodegib (total 72 weeks), followed by 52 weeks treatment-free follow up Receives: Drug: Vismodegib; Drug: Placebo |
| Vismodegib Induction Followed by Intermittent Schedule | Experimental | Vismodegib beginning with 24 weeks induction followed by intermittent schedule 8 weeks placebo, 8 weeks vismodegib (total 72 weeks), followed by 52 weeks treatment-free follow up Receives: Drug: Vismodegib; Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Percent Change From Baseline in the Number of Clinically Evident Basal Cell Carcinomas at Week 73 (After 72 Weeks of Treatment)
The total number of clinically evident basal cell carcinomas = the total number of target and/or non-target lesions present in individual participants.
Measured: Baseline; Week 73
Secondary outcomes (11)
Percentage of Participants Who Discontinued Study Treatment Due to Tolerability Issues
The percentage of participants who discontinued study treatment (due either to adverse event, refusal of treatment, or withdrawal of consent) was summarized by treatment group.
Measured: Baseline to Week 73
Mean Percent Change From Baseline in Total Size of Three Target Basal Cell Carcinoma Lesions in Individual Participants at Week 73
The three target basal cell carcinoma lesions = the three largest visible lesions, at least 5 mm in the longest diameter, in individual participants.
Measured: Baseline; Week 73
Percentage of Participants With at Least 50% Reduction in the Number of Basal Cell Carcinomas at Week 73
Measured: Baseline; Week 73
Percentage of Participants With New Basal Cell Carcinomas at Week 73
Measured: Baseline; Week 73
Percent Change in Total Number of Basal Cell Carcinomas Relative to Baseline at Week 85 (12 Weeks Following End of Treatment) (Recurrence Rate)
Measured: Baseline; Week 85
Percent Change in Total Number of Basal Cell Carcinomas Relative to Baseline at Week 97 (24 Weeks Following End of Treatment) (Recurrence Rate)
Measured: Baseline; Week 97
Percent Change in Total Number of Basal Cell Carcinomas Relative to Baseline at Week 125 (52 Weeks Following End of Treatment) (Recurrence Rate)
Measured: Baseline; Week 125
Percentage of Participants Experiencing Any Adverse Event
Measured: Up to 125 weeks
Percent Change From Baseline in the Skindex-16 Symptom Domain Score at Week 73
The Skindex-16 is a patient-reported outcome health questionnaire. Participants were asked about their symptoms, and their answers were combined into a composite Symptom Domain Score. Scores range from 0 ("never bothered") to 100 ("always bothered").
Measured: Baseline; Week 73
Percent Change From Baseline in the Skindex-16 Emotion Domain Score at Week 73
The Skindex-16 is a patient-reported outcome health questionnaire. Participants were asked about their emotional state, and their answers were combined into a composite Emotion Domain Score. Scores range from 0 ("never bothered") to 100 ("always bothered").
Measured: Baseline; Week 73
Percent Change From Baseline in the Skindex-16 Function Domain Score at Week 73
The Skindex-16 is a patient-reported outcome health questionnaire. Participants were asked about their ability to function, and answers were combined into a composite Function Domain Score. Scores range from 0 ("never bothered") to 100 ("always bothered").
Measured: Baseline; Week 73

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Vismodegib in people with Basal Cell Carcinoma, run by Hoffmann-La Roche at 58 sites in 10 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 58 sites in United States, France, Germany, Italy, Spain and 5 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 4 Aug 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean Percent Change From Baseline in the Number of Clinically Evident Basal Cell Carcinomas at Week 73 (After 72 Weeks of Treatment) (time frame: Baseline; Week 73). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01815840, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2017.
