Keywords: Keratocystic odontogenic tumor KCOT
Sponsor: NYU College of Dentistry
Start date: 2015-10-27; Completion date: 2019-08-01
Enrollment: 2 participants; Allocation: NA; Intervention model: SINGLE_GROUP

Brief summary:
The purpose of this study is to determine how well a daily dose of 150 mg of Erivedge (vismodegib) reduces Keratocystic odontogenic tumor (KCOT) size, and to evaluate the safety of this dose. Erivedge is FDA-approved for use in adults with a specific type of skin cancer. However, the drug is experimental for patients with KCOT.

Detailed description:
This is a single-center, interventional, single-arm, open-label, two-cohort clinical trial. A total of 20 patients will be enrolled (10 with NBCCS-associated KCOT and 10 with sporadic KCOT) over a period of 2 years. This is a 3 year study where each patient will undergo up to 1 year of treatment and up to 2 years of post-treatment follow-up.

All patients will be assessed for safety and efficacy of the study drug GDC-0449 (Vismodegib).

Arms: arm 1: The 150-mg vismodegib drug product is a hard gelatin capsule formulation for oral administration. This study involves one year of treatment with Erivedge (150 mg/day) plus two years of follow-up.
Interventions: intervention 1: vismodegib
Intervention descriptions: intervention 1: vismodegib is a synthetic, small molecule inhibitor of the sonic Hh pathway, which is involved in tumorigenesis, thus providing a strong rationale for its use in the treatment of a variety of cancers.

INTRODUCTION 
1.1
Disease 
Background
The keratocystic odontogenic tumor (KCOT) is a benign odontogenic neoplasm that has 
destructive and infiltrative behavior [1]. KCOT can occur as part of nevoid basal cell 
carcinoma syndrome (NBCCS) or as a sporadic case. KCOTs are the most prominent 
feature of NBCCS and they are present in 65-100% of cases [2]. Four to five percent of 
KCOT patients have NBCCS [3]. Although KCOTs are benign, they tend to be aggressive, 
with local invasion of bony structures, extensive growth, and potential for substantial 
disfigurement  [4]. This condition has a high recurrence rate and it is estimated that after 
initial treatment with various procedures recurrence ranges from 2.5% to 62.5%[5];[6]. 
The only therapeutic option for patients affected by KCOT is surgery which can involve 
significant destruction of tissue; often multiple surgeries are required. Thus, the 
management of patients with KCOT has challenged and frustrated both patients and 
providers[6]. 
Research findings suggest that mutations in PTCH1 are frequent in both sporadic KCOT 
(29%) and NBCCS-associated KCOT (approximately 88%). Thus PTCH1 gene mutations 
may play a significant role in the pathogenesis of NBCCS and the related sporadic 
tumors  [7]. In this study, we plan to test GDC-0449 (Vismodegib) as novel treatment in 
two groups of patients: NBCCS-associated KCOT and sporadic KCOT cohort. The 
inclusion of this two-group cohort is based on the evidence that mutations of the 
hedgehog (Hh) pathway are present in both groups and consequently all patients 
affected by KCOT may benefit from a systemic Hh pathway antagonist. 
We hypothesize that an inhibitor of the sonic Hh can be an important therapeutic 
advancement in the treatment of KCOT. This study proposes to test GDC-0449 
(Vismodegib) for treating patients with KCOT. This drug has the potential to reverse 
KCOT proliferation. GDC-0449 may be useful as a neo-adjuvant prior to surgery in 
patients with KCOT or may be a surgery substitute in some cases. The use of GDC-
0449 prior to surgery may lead to tumor shrinkage and reduce the extent of required 
surgery or eliminate the need for surgery completely.
1.2
Rationale for the Selection of Vismodegib
GDC-0449 is a synthetic, small molecule inhibitor of the sonic Hh pathway, which is 
involved in tumorigenesis, thus providing a strong rationale for its use in the treatment of 
a variety of cancers. Phase I clinical trials in patients with advanced basal cell 
carcinoma (BCC) and medulloblastoma (MB) highlighted an objective response to GDC-
0449. Reported side effects were minor, with only one grade 4 adverse event. 
Phase II trials on GDC-0449 for the treatment of advanced BCC, metastatic colorectal 
cancer, ovarian cancer, MB and other solid tumors have recently been completed[8]. 
Because of its low toxicity and specificity for the Hh pathway, this drug has potential 


Page 5 of 63

advantages compared with conventional chemotherapy, and may also be used in 
combination treatments. 
On 30 January 2012, the U.S. Food and Drug Administration (FDA) approved 
ERIVEDGE® (vismodegib) capsules for the treatment of adults with metastatic basal 
cell carcinoma (mBCC), or with locally advanced basal cell carcinoma (laBCC) that has 
recurred following surgery or who are not candidates for surgery, and who are not 
candidates for radiation. On 12 July 2013, vismodegib was approved for the treatment 
of adult patients with symptomatic metastatic basal cell carcinoma and locally advanced 
basal cell carcinoma inappropriate for surgery or radiotherapy based on a conditional 
marketing authorization from the European Medicines Agency (EMA).
Recently it was reported that GDC-0449 was effective in treating recurrent KCOTs in a 
single patient [9]. The patient was a 55-year-old man with NBCCS. In addition to having 
multiple BCCs over a 25 year period the patient had three mandibular KCOTs that had 
been unsuccessfully treated with surgery, chemotherapy and radiation. The patient was 
started on daily oral GDC-0449 for control of his BCCs. In addition to having resolution 
of his BCCs at 12-week follow-up he had complete resolution of the three mandibular 
KCOTs, as documented by dental radiographs, after 2 years of GDC-0449 therapy.
The dose of Vismodegib chosen in this study is the same as the FDA-approved dosing 
for the treatment of adults with metastatic basal cell carcinoma since the expected 
activity of that drug dose and regimen against keratocystic odontogenic tumor is 
expected to be similar to basal cell carcinoma, and is consistent with doses under study 
in the above noted phase I and II studies of other types of cancers.
There is no prior clinical research experience using Vismodegib for the indication of 
KCOT.  Therefore, Vismodegib will be used according to the FDA approved dose of 150 
mg orally once daily.
1.3
Clinical Experience, Vismodegib Safety and Efficacy
Background on Vismodegib
Vismodegib is a small molecule inhibitor of SMO developed by Genentech, Inc. for the 
treatment of tumors in which the Hh signaling pathway appears to contribute to the 
development and maintenance of tumorigenesis.  Vismodegib, a systemic Hh pathway 
antagonist, has been shown to have oral bioavailability and potent anti-tumor activity in 
a variety of primary human tumor xenografts and tumor cell line xenograft models (see 
the Vismodegib Investigator’s Brochure and the U.S. package insert for further details).

1.3.1.1 Basal Cell Carcinoma
Phase I Study SHH3925g - Safety and Pharmacokinetics Assessment
A Phase I, company-sponsored clinical trial (SHH3925g) assessed the safety and 
pharmacokinetics (PK) of vismodegib and responses of metastatic BCC (mBCC) or 
locally advanced BCC (aBCC) to the drug [10]. Thirty-three patients with mBCC or 
locally aBCC received oral vismodegib at one of three doses: 17 patients received 150 
mg per day, 15 patients received 270 mg per day, and 1 patient received 540 mg per 
day (median duration of treatment was 9.8 months). Of the 33 patients, 18 had an 
objective response to vismodegib, according to assessment on imaging (7 patients), 
physical examination (10 patients), or both (1 patient). Of the patients who had a 
response (see Table 1), 2 had complete responses (CRs) and 16 had partial responses 
(PRs). The other 15 patients had either stable disease (11 patients) or progressive 
disease (4 patients). Eight Grade 3 adverse events (AEs) that were deemed to be 
possibly related to the study drug were reported in 6 patients (see Table 2), including 
fatigue (4 AEs), hyponatremia (2 AEs), muscle spasm (1 AE), and atrial fibrillation (1 
AE). One patient withdrew from the study because of AEs.

Phase II Study ERIVANCE (SHH4476g) in Metastatic and Locally Advanced Basal 
Cell Carcinoma
A multicenter, international, two-cohort, nonrandomized, pivotal, Phase II, company-
sponsored study (SHH4476g) enrolled patients with mBCC and those with locally aBCC 
who had inoperable disease or for whom surgery was inappropriate (because of 
multiple recurrences and a low likelihood of surgical cure, or substantial anticipated 
disfigurement) [11]. In 33 patients with metastatic BCC (see Table 3), the independently 
assessed response rate was 30% (95% confidence interval [CI], 16 to 48; p=0.001). In 
63 patients with locally aBCC (see Table 4), the independently assessed response rate 
was 43% (95% CI, 31 to 56; p<0.001), with complete responses in 13 patients (21%). 
The median duration of response was 7.6 months in both cohorts at the time of data 
cutoff.  Muscle spasms, alopecia, dysgeusia, weight loss, and fatigue occurred in more 
than 30% of patients, whereas serious adverse events (SAEs) were reported in 25% of 
patients. Seven deaths due to AEs were reported and none of the deaths were related 
to vismodegib.

Based on the results of this pivotal trial, vismodegib was approved on 30 January, 2012 
by the US Food and Drug Administration (FDA) for the treatment of adults with mBCC, 
or with locally aBCC that has recurred following surgery or who are not candidates for 
surgery, and who are not candidates for radiation. [12].

Expanded Access Study (SHH4811g) in Advanced BCC
An open-label, single-arm, multicenter, expanded access study (SHH4811g) of an oral 
repeating dose of vismodegib was conducted in patients with locally aBCC or mBCC, 
who are otherwise without satisfactory treatment options. Safety of vismodegib and 
objective response in patients with measurable disease (RECIST v1.0) were assessed 
(Weiss G, et al. 2012). The study has been completed following FDA approval and 
commercial availability of vismodegib.
Among 95 efficacy evaluable patients (56 patients with locally aBCC and 39 patients 
with mBCC) at the time of final analysis data cutoff date of 23 April 2012 the observed 
objective response rates (see Table 7) were 46.4% (95% CI, 33.0%, 60.3%) for patients 
with locally aBCC (n = 56) and 30.8% (95% CI, 17.0%, 47.6%) for patients with mBCC 
(n = 39). CR, PR, and stable disease (SD) were observed in 10.7%, 35.7%, and 48.2%, 
respectively, of patients with locally aBCC; no patients in this cohort exhibited 
progressive disease (PD) as best response. For patients with mBCC, CR, PR, and SD 
rates observed were 5.1%, 25.6%, and 51.3%, respectively. In this cohort, 7.7% of 
patients exhibited PD as best response. Among patients with locally aBCC who 
responded the median and mean times to response were 2.6 months and 3.5 months, 
respectively; and among patients with mBCC who responded the median and mean 
times to response were 2.6 months and 3.8 months, respectively.
As of the final analysis data cutoff date of 23 April 2012, 116 of 119 safety evaluable 
patients (97.5%) experienced at least one adverse event (22 SAEs total, see Table 8). 


Page 12 of 63

Adverse events that had the highest reported occurrences ( 20%) in 119 safety 
evaluable patients were: muscle spasms (84 patients; 70.6%), dysgeusia (84 patients; 
70.6%), alopecia (69 patients; 58.0%), and diarrhea (30 patients; 25.2%). Only one of 
22 SAEs (4.5%) was assessed as being related to treatment with vismodegib:  a Grade 
3 muscle spasm, reported in 1 patient. There have been three deaths among 119 
safety-evaluable patients (2.5%); 2 assessed as unrelated to study drug, and 1 patient 
with PD.

Phase II BCNS Study (SHH4685s) 
The anti–BCC efficacy of vismodegib was tested in a randomized, double-blinded, 
placebo-controlled, Investigator-sponsored trial in Gorlin syndrome (BCNS) patients 
with surgically eligible BCCs [13-15].  Forty-one patients were randomized 2:1 to 
receive oral vismodegib (n=26) or placebo (n=15). After a mean follow up of 8 months 
(range, 1 to 15 months), the per-patient rate of new surgically eligible BCCs (SEBs) was 
lower with vismodegib than with placebo (2 vs. 29 cases per group per year, p<0.001), 
as was the size (percent change from baseline in the sum of the longest diameter) of 
existing clinically significant BCCs (–65% vs. –11%, p=0.003). In some patients, all 
BCCs clinically regressed.  No tumors progressed during treatment with vismodegib.  
Patients receiving vismodegib routinely had Grade 1 or 2 AEs of loss of taste, muscle 
cramps, hair loss, and weight loss.  Overall, 54% of patients (14 of 26) receiving 
vismodegib discontinued drug treatment due to AEs.  At 1 month, vismodegib use had 
reduced the Hh pathway's target-gene expression in BCC cells by 90% (p<0.001) and 
diminished tumor-cell proliferation, but apoptosis was not affected.  No residual BCC 
was detectable in 83% of biopsy samples taken from sites of clinically regressed BCCs.  
At the second pre-specified interim analysis, a data safety and monitoring board 
concluded that the pre-determined threshold for a significant difference between the two 
groups had been reached (p<0.0113), and the treatment with placebo in this arm was 
terminated.  AEs reported in   10% of patients are summarized in Table 9 See the 
Vismodegib Investigator’s Brochure and the U.S. package insert for additional details on 
nonclinical and clinical studies on vismodegib.

Phase II STEVIE (MO25616) Safety Study
Study MO25616 is an ongoing Phase II open-label, single-arm, multicenter (ex-U.S.) 
study of vismodegib in patients with locally aBCC or mBCC who are otherwise without 
satisfactory treatment options.  The primary objective is to assess the safety of 
vismodegib in patients with locally aBCC or mBCC.  Secondary objectives are to assess 
the overall response (according to RECIST Version 1.1) in those patients with 
measurable disease as permitted by local regulatory requirement and to assess other 
efficacy parameters such as time to response, duration of response, PFS and overall 
survival (OS).
All patients receive 150 mg vismodegib orally (PO) daily (QD) until investigator-
assessed PD, unmanageable toxicities, or withdrawal from study (investigator/patient 
request) or termination by the Sponsor).
As of 6 November 2013, a total of 1228 patients have been enrolled into the study.  
Results of an interim analysis, when a total of 501 patients could be followed for 1 year, 
are presented below.
As of the cutoff date of 6 November 2013, safety data were available for 500 patients 
(469 with locally aBCC and 31 with mBCC) with follow up information for at least 
3 months after treatment.  Overall, 492 of 500 safety-evaluable patients (98.4%) 
experienced at least one AE.  The most frequently reported AEs, regardless of 
relationship to study drug, in descending order of frequency, were:  muscle spasms 
(63.2%), alopecia (61.0%), dysgeusia (53.8%), weight decreased (32.4%), asthenia 
(28.2%), decreased appetite (25.4%), and ageusia (22.4%).
As of 6 November 2013, 210 of 500 safety-evaluable patients (42.0%) experienced 
Grade 3−5 treatment-emergent adverse events (TEAEs).  Of 500 patients, 165 patients 
(33.0%) experienced a Grade 3 AE, 24 patients (4.8%) experienced a Grade 4 AE, and 


Page 15 of 63
14 Oct 2016
21 patients (4.2%) experienced a Grade 5 AE.  All of the Grade 5 AEs were considered 
by investigator to be unrelated to treatment with vismodegib except for cardio-
respiratory arrest and myocardial infarction.
Of the 500 patients, 107 (21.4%) experienced SAEs.  The most common events were in 
the following system organ classes:  infections and infestations, 30 patients (6.0%); 
neoplasms (benign, malignant, and unspecified, including cysts and polyps), 16 patients 
(3.2%); general disorders and administration site conditions, 12 patients (2.4%); 
nervous system disorders, 12 patients (2.4%); cardiac disorders, 11 patients (2.2%); 
injury, poisoning and procedural complications, 10 patients (2.0%); and metabolism and 
nutrition disorders, 10 patients (2.0%).
As of 6 November 2013, there have been 29 deaths among 500 safety-evaluable 
patients.  The causes of death were PD in 4 patients, AE in 20 patients, and 5 patients 
with “other” as cause of death.  Most patient deaths were considered unrelated to 
treatment with vismodegib.  Two deaths (cardiopulmonary arrest and cardiac infarction) 
were assessed by the investigator as related to vismodegib; however, both patients had 
significant risk factors and comorbidities.  Both events were considered by the 
investigator to be related because of the temporal relationship between the onset of the 
event and administration of vismodegib; therefore, an association could not be 
excluded.
As of 6 November 2013, 400 of 500 patients (80%) treated during Study MO25616 had 
discontinued study drug.  Reasons for discontinuation of study drug included: AE 
(178 patients, 35.6%); progression of disease (70 patients, 14.0%); patient request 
(62 patients, 12.4%); death (10 patients, 2.8%); investigator request (14 patients, 2.8%); 
lost to follow-up (4 patients, 0.8%); and other (62 patients, 12.4%).
The majority of patients (98.2%) in Study MO25616 (STEVIE) experienced TEAEs.  The 
most common ( 20%) TEAEs included muscle spasm (63.2 %), alopecia (61.0%), 
dysgeusia (53.8%), weight decreased (32.4%), asthenia (28.2%), decreased appetite 
(25.4%), and ageusia (22.4%).  Twenty-four (4.8%) Grade 4 events and 21 (4.2%) 
Grade 5 events were reported.  Two of the deaths were considered related to 
vismodegib treatment (cardio-respiratory arrest and myocardial infarction).  There were 
107 (21.4%) patients who reported SAEs.  Common SAEs that were reported in  1% of 
patients were pneumonia (1.8%, n  9), general physical health deterioration (1.4%, 
n  7), and dehydration (1.0%, n  5).
Interim results of the STEVIE study demonstrate that vismodegib is generally well 
tolerated in a patient population that is representative of patients treated in routine 
clinical practice, with a safety profile consistent with that previously observed in other 
vismodegib studies.  Investigator-assessed response rates are consistent with those 
reported in the ERIVANCE study and confirm high rates of tumor control.
As the trial is ongoing, efficacy analyses will be presented at final analysis.

Phase II Operable Basal Cell Carcinoma (SHH4812g) Study
The ability of vismodegib to induce complete histological clearance (CHC) of BCC 
tumors, an important step in assessing the role of the drug in the setting of smaller 
resectable lesions, was examined in a single-arm, 3-cohort, Phase II study (Sofen et al. 
2015).  Patients in the trial were required to have one clinically operable, nodular BCC 
lesion on the scalp (0.5  2.0 cm maximum diameter) or in the "cape" area (chest, 
shoulders, or upper back; 1.0  3.0 cm maximum diameter).  The nodular BCC required 
a positive biopsy that was limited to  25% of the target lesion.  After 12 weeks of oral 
vismodegib (150 mg QD), patients were assessed clinically and then underwent 
excision of the target tumor site for pathologic assessment of residual carcinoma, 
followed by re-excision of the tumor site for margin assessment using standard Mohs 
techniques. 
Efficacy objectives for CHC were not met in this study.  The CHC rates were 42% 
(10/24) in Cohort 1, 16% (4/25) in Cohort 2, and 44% (11/25) in Cohort 3; these 
clearance rates were not statistically significant (p-values of 0.8463, 0.9668, and 
0.7878, respectively).  The low response rate in Cohort 2 (4 [16%] of 25 patients) 
indicates a lack of durable response.  Investigator-assessed clinical response (CR and 
PR) did not correlate with CHC.  Time to complete clinical clearance in patients in 
Cohorts 1 (10 patients), 2 (9 patients), and 3 (18 patients) with investigator-assessed 
CR, the time to first CR was 59.5 days (95% CI: 28.0  80.0 days), 84.0 days (95% CI: 
27.0  120.0 days), and 60.0 days (95% CI: 55.0  86.0 days), respectively. 
No new safety signals were noted for patients in this study after dosing with vismodegib 
150 mg QD PO.  No deaths occurred during this study.  The safety profile of vismodegib 
150 mg QD was similar among the 3 cohorts.  The data generally showed reversibility of 
muscle spasms, dysgeusia, and ageusia 6 to 12 weeks after drug discontinuation, and 
reversibility of delayed-onset alopecia in most patients during the 24-week follow-up 
period in Cohort 2.
Efficacy objectives for CHC were not met in this study.
1.3.1.2 Medulloblastoma
Data from a phase II clinical trial evaluated vismodegib treatment at 150 mg QD PO in 
adult patients with medulloblastoma that was recurrent after or progressive while 
receiving standard (n=40) [16, 17]. Patients were stratified by histologic subtypes based 
on immunohistochemical (IHC) analysis into three strata: non-SHH group, SHH group, 
and indeterminate group. The primary endpoint was objective response rate as 
assessed by RECIST using independent review. Responses must be sustained at least 
8 weeks. The study met its primary endpoint of sustained objective response, with 3/20 
patients in SHH group exhibiting sustained responses. Secondary efficacy endpoints 
were consistent with the primary endpoint. Grade 3-4 TEAEs reported were 
lymphocytopenia, thromboembolic event, syncope, back pain, myalgia, seizure, and 
hypophosphatemia.

1.3.2 Malignancies with Ligand Driven Hh Signaling 
1.3.2.1 Colorectal Cancer
A randomized phase II clinical trial evaluated addition of vismodegib or placebo to 
standard chemotherapy (mFOLFOX-6 or FOLFIRI) plus bevacizumab in patients with 
untreated metastatic colorectal cancer (n=199)[18]. Choice of chemotherapy regimen 
was based on investigator decision. The primary endpoint was improvement in 
progression-free survival (PFS). The study failed to meet its primary endpoint of 
improved PFS vs. chemotherapy + placebo (hazard ratio = 1.25 [90%, CI 0.89 -1.76], p 
=0.28) Secondary efficacy endpoints were consistent with the primary endpoint. The 
TEAEs (all grades) that differed in frequency by 10% or more vs. placebo were 
vomiting, asthenia, weight loss, decreased appetite, dehydration, muscle spasms, and 
dysgeusia. Grade 3-5 TEAEs that differed in frequency by 5% or more vs. placebo were 
fatigue, nausea, asthenia, mucositis, peripheral sensory neuropathy, weight loss, 
decreased appetite, and dehydration.
1.3.2.2 Ovarian Cancer
A randomized phase II clinical trial evaluated the use vismodegib or placebo as 
maintenance treatment for patients with ovarian cancer in second or third complete 
remission (n=104)[19]. The primary endpoint was improvement of PFS. The study failed 
to meet its primary endpoint of improved PFS vs. placebo (hazard ratio=0.79 95%CI 
0.46-1.35, p=0.39). TEAEs occurring in greater than 10% of vismodegib treated patients 
were dysgeusia/ageusia, muscle spasms, alopecia, nausea, fatigue, constipation, 
abdominal pain, decrease appetite, upper abdominal pain, arthralgia, vomiting and 
hypomagnesemia.
1.3.2.3 Pancreatic Cancer
A randomized phase II clinical trial evaluated addition of vismodegib or placebo to 
standard chemotherapy (gemcitabine) in patients with untreated metastatic pancreatic 
cancer (n=106)[20]. The primary endpoint was improvement in progression-free 
survival. The study failed to meet its primary endpoint of improved PFS vs. 
chemotherapy + placebo (HR = 0.81 95%CI 0.54 - 1.21, p=0.3) Secondary efficacy 
endpoints were consistent with the primary endpoint. The frequency of Grade ¾ TEAEs 
reported vs. placebo (V/P) were neutropenia (32%/28%), hyponatremia (4%/15%), 
fatigue (13%/8%), hyperglycemia (23%/19%), elevated alanine aminotransferase (ALT; 
13%/9%). TEAEs that differed in frequency by 10% or more vs. placebo were vomiting, 
asthenia, weight loss, decreased appetite, and dehydration.
1.3.2.4 Glioblastoma Multiforme
A phase II clinical trial evaluated vismodegib treatment at 150 mg QD PO in patients 
with glioblastoma multiforme that was recurrent after or progressive while receiving 
standard treatment (n=40)  [21]. The primary endpoint was improvement in PFS at 6 
months. The study failed to meet its primary endpoint of improved PFS at 6 months 
(median PFS 1.8 months 95%CI 1.40 - 1.9 months) Secondary efficacy endpoints were 


Page 18 of 63
14 Oct 2016
consistent with the primary endpoint. TEAE reported were abdominal infection, 
abdominal pain, atrial flutter, fatigue, hypophosphatemia, lymphocytopenia, and 
thrombocytopenia (1 patient each).
1.3.2.5 Gastric Cancer
A randomized phase II clinical trial evaluated addition of vismodegib or placebo to 
chemotherapy (mFOLFOX-6) in patients with untreated metastatic gastric cancer 
(n=124)[22]. The primary endpoint was improvement in PFS. The study failed to meet 
its primary endpoint of improved PFS vs. chemotherapy + placebo (hazard ratio = 1.03 
95%CI 0.69 - 1.55, p=0.64) Secondary efficacy endpoints were consistent with the 
primary endpoint. No significant differences in the rates of common grade ¾ TEAEs (> 
5% incidence) were observed between the vismodegib and placebo arms. The rates of 
grade ½ TEAEs were comparable with no significant differences except for a higher 
incidence of dysgeusia in the vismodegib arm (42%/16%, p=0.003). 
1.3.2.6 Small Cell Lung Cancer
A randomized phase II clinical trial evaluated addition of vismodegib or cixutumumab 
(IMC-A12) to standard chemotherapy (cisplatin/etoposide) in patients with untreated 
extensive stage SCLC (n=155)[23]. The primary endpoint was improvement in PFS. The 
study failed to meet its primary endpoint of improved PFS vs. cisplatin/etoposide 
chemotherapy (hazard ratio = 1.32, p=0.21) Secondary efficacy endpoints were 
consistent with the primary endpoint. Grade ¾ TEAEs reported (chemotherapy alone 
vs. chemotherapy+vismodegib) included anemia (25%/ 9%), febrile neutropenia 
(15%/13%), 
neutropenia 
(48%/47%), 
thrombocytopenia 
(22%/6%),

STUDY OBJECTIVES
2.1
Primary Objectives
The primary objectives of the study are:
a. To evaluate the efficacy of GDC-0449 in reducing KCOT size (shrinkage) in 
NBCCS-associated KCOT and sporadic KCOT patients following 6 to 12 months 
of ingestion of 150 mg/day, up to 1 year of treatment and up to 2 years of post-
treatment follow-up.
b. To evaluate the safety of this dose of GDC-0449 in these patients. 
Tumor response (reduction in tumor volume and shrinkage) will be measured by 
volumetric CT scan.
Time Frame: Efficacy will be assessed at 1 year and 2 years after the study medication 
is stopped. Patients will undergo evaluation for 3 years (up to 1 year of treatment and 
up to 2 years of post-treatment follow-up). All patients will participate in the assessment 
of the safety and tolerability of the study drug. Safety monitoring will capture risks 
related to study participation and adverse events related to the study drug.

2.2
Secondary Objectives
The secondary objectives of the study are:
a. To determine the time of response of a GDC-0449 anti-proliferative effect (i.e. 
tumor shrinkage) after administration of the drug up to one year or until treatment 
is stopped; 
b. To assay germ line PTCH1 mutations before treatment with GDC-0449 in 
patients with NBCCS-associated KCOT; 
If tumor removal is required, to assess tumor PTCH1 mutations before and after 
treatment with GDC-0449 in NBCCS-associated KCOT and sporadic KCOT in order to 
determine the correlation of tumor response and the presence of tumor PTCH1 
mutation.

STUDY DESIGN
3.1
Description of the Study
This is a single-center, interventional, single-arm, open-label, two-cohort clinical trial. A 
total of 40 patients will be screened in order for 20 patients to be enrolled (10 with 
NBCCS-associated KCOT and 10 with sporadic KCOT) over a period of 2 years. This is 
a 3 year study where each patient will undergo up to 1 year of treatment and up to 2 
years of post-treatment follow-up. If a patient is experiencing an ongoing adverse event 
at the time of the study completion, he/she will be followed-up until resolution of the 
adverse event or until the condition has stabilized. The same applies to patients who 
are withdrawn from the study due to adverse events.
It is estimated that it will take approximately 2 years to recruit 20 patients for the study 
(10 with NBCCS-associated KCOT and 10 with sporadic KCOT). 
All patients will be assessed for safety and efficacy of the study drug GDC-0449 
(Vismodegib).

4.1.3 Subject Recruitment and Screening
Clinicians and staff at the clinical study site will be made aware of the study and trained 
on the eligibility criteria, the enrollment procedures and study procedures. A study 
coordinator will be available at the site. All patients who arrive at the clinic should be 
considered potentially eligible. The study coordinator will review appointment schedules 
and information available at the time of the patient appointments to identify potential 
subjects and to rule out patients who do not fall into the defined study population. Either 
the clinician or the study coordinator will inform the potential subjects about the study 
and ask if they are interested in participating. Patients will be informed that their 
participation in the study, or not, will have no influence on their clinical management. If 
the patient expresses interest, then the clinician or study coordinator will assess the 
patient’s eligibility (screening for eligibility does not require any testing) and answer any 
questions the patient might have about the study. A signed consent form documenting 
informed consent for eligible subjects will be obtained prior to the start of any study 
procedures.  Advertisements such as flyer and web ad will be used in this study for 
recruitment of subjects.  Web ad will be posted on NYU Bluestone website. All 
advertisements will be approved by an Institutional Review Board prior to posting or 
dissemination.  A doctoral referral letter will be sent out via email and/or mail to oral and 
maxillofacial surgeons, asking for referral of eligible subjects who might be interested in 
the study.  A publically available directory will be used to obtain the contact information 
of the oral and maxillofacial surgeons.  A doctoral referral letter will be accompanied 
with the drug package insert, inclusion/exclusion criteria, and the study flyer.
4.2
Study Treatment 
This is a single-center, interventional, single-arm, phase II, open-label, two-cohort 
clinical trial. A total of 40 patients will be screened in order for 20 patients to be enrolled 
(10 with NBCCS-associated KCOT and 10 with sporadic KCOT) over a period of 2 
years. Only patients with a diagnosis of recurrent (maxillary or mandibular) sporadic 
KCOT or NBCCS-associated KCOT (single or multiple) will be recruited. All patients will 
receive 150 mg/day of GDC-0449 (Vismodegib) orally for 1 year.  All patients will be 
assessed for safety and efficacy of the study drug GDC-0449 (Vismodegib).
This is a 3 year study where each patient will undergo up to 1 year of treatment and up 
to 2 years of post-treatment follow-up.
The Sponsor Investigator of the study will ensure maintenance of complete and 
accurate records of the receipt, dispensation, and disposal or return of all Vismodegib in 
accordance with 21 Code of Federal Regulations (C.F.R.), Part 312.57 and 312.62 and 
Genentech requirements.
Vismodegib Dosage 


Page 24 of 63
14 Oct 2016
The recommended dose of Vismodegib is 150 mg taken QD PO until disease 
progression or until unacceptable toxicity. Vismodegib may be taken with or without 
food. Swallow capsules whole. 
Do not open or crush capsules
If a dose of vismodegib is missed, do not make up that dose; resume dosing with 
the next scheduled dose.
Vismodegib Dose and Schedule Modifications
Vismodegib dose modifications and schedule modifications during the study are not 
recommended due to the pharmacokinetic characteristics of the drug (see Vismodegib 
Investigator Brochure v10, Section 5.9.3). Briefly, vismodegib’s pharmacokinetic profile 
is a result of high affinity, reversible binding to Alpha-1 acid Glycoprotein (AAG) and 
binding to albumin, in addition to solubility limited absorption and slow metabolic 
elimination properties[24]. Initiation of less frequent administration schedules than 
the approved dose and schedule of vismodegib of 150 mg orally once daily,(i.e. 150 
mg three times weekly [TIW] or 150 mg once weekly dosing), was associated with 
marked 
decrease 
in 
the 
pharmacologically 
active 
unbound 
fraction.
Unbound steady-state vismodegib concentrations were 60% and 85% lower for the TIW 
and QW dose groups, respectively, relative to the QD dose group [25, 26].  Such 
decreases may be associated with loss of vismodegib activity based on findings from 
nonclinical models. Integrated PK/pharmacodynamic modeling of vismodegib in 
xenograft models has revealed a steep relationship between pathway modulation (GLI1 
inhibition) and anti-tumor effect, suggesting that even small reductions in exposure 
could lead to dramatic loss in vismodegib activity (see Vismodegib Investigator’s 
Brochure v10, Section 4.1.2.8)
Dose reduction of vismodegib is not permitted as there is only a 150-mg capsule 
strength available. Capsules should not be opened or crushed. If a treatment 
interruption occurs, and it is determined that vismodegib will be re-started, the original 
dose will be maintained
Vismodegib Overdosage
There is no information on overdosage in humans. In clinical trials, ERIVEDGE capsule 
was administered at 540 mg QD PO; exposure did not increase between 150 mg and 
540 mg daily. 
Vismodegib Clinical Formulation and Storage 
For the clinical studies, hard gelatin capsules containing 150 mg vismodegib are 
available. 
The 150-mg vismodegib drug product is a hard gelatin capsule formulation for oral 
administration. The capsule fill consists of vismodegib and the following excipients: 


Page 25 of 63
14 Oct 2016
microcrystalline cellulose PH101, lactose monohydrate, sodium lauryl sulfate, povidone 
K29/32, sodium starch glycolate, talc, magnesium stearate, and purified water. All of 
these excipients are compendial (USP/NF-EP) grade. The capsule shell consists of 
gelatin, red iron oxide, black iron oxide, and titanium dioxide. A compendial-grade black 
printing ink may be used.
Vismodegib capsules should be stored in the recommended storage conditions 
at15°C−30°C Information on the shelf life of the capsules is provided on the label. 
Vismodegib Packaging and Labeling 
Genentech, Inc., the manufacture of ERIVEDGE®, will label and package the study drug 
on behalf of the Sponsor Investigator for this clinical research study.  
Please refer to the Master Label Certification from Genentech, Inc. for detailed 
information about labeling and packaging for the study drug.
Preparation and Administration of Study Drug
Study drug will be supplied by Genentech, Inc in labeled 75cc HDPE bottle.  Each bottle 
will contain 32 hard capsules Vismodegib 150mg. The first dose of study drug will be 
given during a study visit and the subjects will be monitored for 6 hours after taking the 
drug for the first time. After the first administration, the study drug will be given to the 
study subjects to be taken at home.
Subject Compliance Monitoring
The study subjects will be given enough study drugs to last until the next visit. 
Dispensing records will document quantities received and quantities dispensed, lot 
number (if applicable), date dispensed, patient identifier number, and initials of the 
person dispensing the study drugs.  Subjects will bring back the study drug bottle with 
any unused study drug at each study visits to monitor their compliance.
Drug Accountability
Receipt of Drug Supplies
Upon receipt of the of the study treatment supplies, an inventory must be performed and 
a drug receipt log filled out and signed by the person accepting the shipment.  It is 
important that the designated study staff counts and verifies that the shipment contains 
all the items noted in the shipment inventory.  Any damaged or unusable study drug in a 
given shipment (active drug or comparator) will be documented in the study files.  The 
investigator must notify study sponsor of any damaged or unusable study treatments 
that were supplied to the investigator’s site.
Storage


Page 26 of 63
14 Oct 2016
The boxes containing the study drug will be stored at room temperature under secured 
conditions with limited access. The study drug will be stored in room #236 in Bluestone 
Center for Clinical Research.  Room #236 is a limited card swipe access secure room 
with approximately 50 square feet of space and approximately 15 linear feet of 
countertop space for processing medication orders. Room #236 contains two security 
cameras which are under 24 hour surveillance by NYU College of Dentistry’s security 
team.
Dispensing of Study Drug
Regular study drug reconciliation will be performed to document drug assigned, drug 
consumed, and drug remaining.  This reconciliation will be logged on the drug 
reconciliation form, and signed and dated by the study team.
Return or Destruction of Study Drug
At the completion of the study, there will be a final reconciliation of drug shipped, drug 
consumed, and drug remaining.  This reconciliation will be logged on the drug 
reconciliation form, signed and dated.  Any discrepancies noted will be investigated, 
resolved, and documented prior to return or destruction of unused study drug.  Drug 
destroyed on site will be documented in the study files.
4.3
Concomitant and Excluded Therapy 
Drugs that Inhibit or Induce Drug Metabolizing Enzymes 
Vismodegib elimination involves multiple pathways. Vismodegib is predominantly 
excreted as an unchanged drug. Several minor metabolites are produced by multiple 
CYP enzymes. Although vismodegib is a substrate of CYP2C9 and CYP3A4 in vitro, 
CYP inhibition is not predicted to alter vismodegib systemic exposure since similar 
steady-state plasma vismodegib concentrations were observed in patients in clinical 
trials concomitantly treated with CYP3A4 inducers (i.e., carbamazepine, modafinil, and 
phenobarbital) and those concomitantly treated with CYP3A4 inhibitors (i.e., 
erythromycin, and fluconazole). 
Drugs that Inhibit Drug Transport Systems 
In vitro studies indicate that vismodegib is a substrate of the efflux transporter P-
glycoprotein (P-gp). When ERIVEDGE is coadministered with drugs that inhibit P-gp 
(e.g. clarithromycin, erythromycin, azithromycin), systemic exposure of vismodegib and 
incidence ofAEs of ERIVEDGE may be increased. 
Drugs that Affect Gastric pH 
Drugs that alter the pH of the upper gastrointestinal (GI) tract (e.g. proton pump 
inhibitors, H2-receptor antagonists, antacids) may alter the solubility of vismodegib and 
reduce its bioavailability. However, no formal clinical study has been conducted to 
evaluate the effect of gastric pH altering agents on the systemic exposure of 
vismodegib. Increasing the dose of ERIVEDGE when coadministered with such agents 


Page 27 of 63
14 Oct 2016
is not likely to compensate for the loss of exposure. When ERIVEDGE is 
coadministered with a proton pump inhibitor, H2-receptor antagonist or antacid, 
systemic exposure of vismodegib may be decreased and the effect on efficacy of 
ERIVEDGE is unknown.
Effects of Vismodegib on Other Drugs
Results of a drug-drug interaction study conducted in cancer patients demonstrated that 
the systemic exposure of rosiglitazone (a CYP2C8 substrate) or oral contraceptives 
(ethinyl estradiol and norethindrone) is not altered when either drug is co-administered 
with vismodegib.
In vitro studies indicate that vismodegib is an inhibitor of CYP2C8, CYP2C9, CYP2C19 
and the transporter BCRP. Vismodegib does not induce CYP1A2, CYP2B6, or 
CYP3A4/5 in human hepatocytes.
4.4
Study Assessments
Study assessments and procedures for efficacy and safety are detailed in Appendix A.  
Patients’ screening information will be recorded on the Screening and Enrollment Log. 
Clinical Laboratories and Vital Signs
Safety evaluations include clinical laboratory assessments as set forth in the Schedule 
of Study Assessments and Procedures in Appendix A. Safety and tolerability will be 
measured by adverse events, physical examination, complete blood count, vital signs, 
and oral cavity assessments.  Details of laboratory procedures are provided in the 
laboratory manual for the study. 
Samples of blood will be taken on selected visits (see Appendix A). 20 mL (inclusive) of 
blood will be obtained by venipuncture on each required visit. Approximately 100 mL of 
blood will be drawn over the course of the study (Screening through the completion of 
the Treatment Phase) for clinical laboratory assessments. Patients consenting to have a 
blood sample drawn for future DNA analysis will have an additional 7-10 mL of blood 
drawn at the baseline visit. Analysis of all clinical blood samples will be made at a 
central clinical laboratory. The investigator and clinical monitor will be provided with a 
list of the normal ranges used by the testing laboratory for all variables assayed during 
the study and a statement of accreditation (or similar) for the laboratory.
Complete blood count, serum pregnancy test, serum chemistry, coagulation time, and 
liver function will be assessed and include the following measures: white blood count, 
hemoglobin, platelets, glucose, uric acid, calcium, phosphorus, sodium, potassium, 
chloride, alkaline phosphatase, albumin, alanine transaminase (ALT), aspartate 
transaminase (AST), BUN and creatinine.
Female patients of childbearing potential will have a urine pregnancy test. A pregnancy 
test will be performed by the study center by use of a dipstick. All laboratory results will 
be reviewed and the reports signed by an investigator. 


Page 28 of 63
14 Oct 2016
Any results considered to be of clinical significance must be dealt with and followed up 
as clinically appropriate. All laboratory results considered to represent an adverse event 
(AE) must be documented in the case report form (CRF). Repeat samples will be taken 
if required for clinical follow up or because the sample is lost or damaged. Any abnormal 
end of treatment clinical laboratory result of clinical significance must be repeated at 
regular intervals until it returns to normal, or until an investigator is satisfied that the 
abnormality is not related to the drug and needs no further investigation. 
Vital signs (blood pressure, heart rate and temperature) will be obtained for safety 
monitoring.
Optional Blood Sample for Future Genetic Testing
If a subject agrees to provide a blood sample for future genetic testing, an additional 
blood sample will be collected at Baseline and also at one year visit if subject has new 
tumor.  Human DNA will be extracted from the blood and stored at the Bluestone Center 
for Clinical Research for up to 10 years to be used for DNA sequencing as part of a 
future study related to KCOT. PCR amplification of exons encoding the open reading 
frame of genes associated with KCOT will be carried out using nested primers prior to 
sequencing PCR products in both the sense and antisense directions.  Identified 
mutations will be confirmed by an independent PCR and sequencing reaction.  The 
genetic testing will not include tests that can identify patients’ risks for other conditions. 
Only users authorized by the Bluestone Center for Clinical Research and Genentech 
would have access to the samples. The stored samples will be labeled with the subject 
code, diagnosis and/or location of the sample. The linking key between subject code 
and subject identity will be maintained by the PI.  The subject may withdraw their 
samples from storage and future use by providing a written request to the PI.
Oral Cavity Assessment, Head & Neck, & Physical Exam
At the scheduled time points, according to the Schedule of Study Assessments and 
Procedures in Appendix A, study personnel will perform a comprehensive oral exam 
consisting of an evaluation of oral hard and soft tissue structures for each patient. Oral 
hard tissue assessments will be performed with a dental mirror on the teeth and bony 
structures.  Oral soft tissues will be performed by examining each patient’s mouth and 
pharynx, including lips, tongue, floor of the mouth, palate, gingiva, alveolar mucosa, 
buccal mucosa, oropharynx, tonsils, uvula, and salivary glands using palpation 
techniques and visualization.  
A complete extraoral physical exam of the head and neck regions will also be noted by 
visualization and bi-manual palpation. This assessment will be performed during the 
baseline visit and the treatment and post-treatment phase of the study. 
In addition to the oral hard tissue assessments, extraoral and head and neck 
examinations, a complete physical exam will be done during the baseline and treatment 


Page 29 of 63
14 Oct 2016
phase of the study. This exam will include the examination of the cardiovascular, 
pulmonary, abdomen and nervous system.
Dermatologic Assessments
A thorough skin examination will be performed by a study investigator for NBCCS-
associated KCOT patients at different time points (see Appendix A for more details). 
The purpose of this exam will be to identify any suspicious lesions. Patients with 
suspicious findings will be referred to a dermatologist as per standard of care. 
Photographs of the lesions will be taken and all findings will be recorded on the relevant 
CRF. Follow-up visits with a dermatologist will be conducted for patients with suspicious 
lesions as per standard of care. All findings by a dermatologist will be kept with the 
study records.
Any abnormal findings will be documented.  Any abnormalities noted at the Baseline 
visit, may be reason to exclude a patient from the study.  At the time of the first study 
drug administration or post-dose, should an adverse event be reported, the investigator 
will determine which safety assessments should be performed.  All findings will be 
recorded on the respective CRF.  
Any clinically significant signs or symptoms that are present at, or during the Baseline 
visit, and that worsen during or after study drug administration, will be recorded as 
adverse events on the adverse event CRF. Non-significant clinical abnormalities will 
also be recorded on the relevant CRF.
Photography
When applicable, any suspicious lesions which are discovered during the skin 
examination will be photographed and filed in the patient’s study chart. Photographs will 
only contain images of the suspicious lesion. The patient’s face will not be visible in the 
photograph.
Panoramic Radiograph and Volumetric CT Scan
Tumor volume will be measured at baseline, and tumor response (reduction in tumor 
volume and recurrence) will be measured during the treatment phase and post-
treatment phase by Panoramic Radiograph and Volumetric CT scan. The use of 
Panoramic Radiograph and Volumetric CT scan to measure the tumor volume are 
obtained for clinical assessment purposes only. No additional scans will be performed 
for research purposes. Disease progression during the treatment phase will be 
classified by an increase of at least 20%, with an absolute change greater than 5 mm in 
tumor size after 3 months of treatment.  KCOTs grow within the bone.  CT scan and 
panoramic radiograph are superior, with regard to sensitivity and specificity, in terms of 
evaluating bone involvement.  
Biopsy and Analysis of the Tumor


Page 30 of 63
14 Oct 2016
If the patient had a previous biopsy performed, a tissue slide will be obtained for study 
purposes and confirmation of KCOT diagnosis.  If clinically indicated, an additional 
biopsy of the tumor will be done and if the patient agrees, the leftover tissue from the 
tumor biopsy will be stored for future genetic analysis related to KCOT. The storing of 
tumor for future genetic analysis is optional and will be stored for 10 years.  These 
additional biopsies will be flash-frozen in liquid nitrogen (LN2) and stored in LN2 at the 
Bluestone Center for Clinical Research. 
The future genetic testing will not include tests that can identify patients’ risks for other 
conditions. Only users authorized by the Bluestone Center for Clinical Research and 
Genentech would have access to the samples. The stored samples will be labeled with 
the subject code, diagnosis and/or location of the sample. The linking key between 
subject code and subject identity will be maintained by the PI.  The subject may 
withdraw their samples from storage and future use by providing a written request to the 
PI.
Assessment of Gene Mutations and Gene Expression in Tumor Specimens: The 
additional fresh-frozen tumor specimens will be subjected to gene mutation and gene 
expression analysis. If no additional fresh-frozen specimen is obtained, the initial biopsy 
samples, which are formalin-fixed, paraffin-embedded (FFPE), will be used instead. 
FFPE tissue scraped from serially cut slides will be deparaffinized using Envirene 
reagent (Hardy Diagnostics, Santa Maria, CA, USA) before isolation of RNA using the 
Roche High Pure FFPE RNA Micro Kit (Roche Diagnostics, Indianapolis, IN). RNA will 
be extracted from fresh-frozen tissue using the High Pure RNA Tissue Kit (Roche 
Diagnostics, Indianapolis, IN). RNA will be reversed transcribed using the High-Capacity 
cDNA Reverse Transcription Kit (Applied Biosystems, Foster City, CA, USA) with 
random primers. PCR will be carried out using the Taqman Universal PCR Master Mix 
(Applied Biosystems), with the following cycling conditions: 50°C for 2 min; 95°C for 10 
min; 40 cycles of 95°C for 15 s, 60°C for 1 min. qRT-PCR profiling of genes associated 
with KCOT will be performed For analyses, gene expression from the genes of interest 
will be normalized to the average cycling threshold (Ct) of three housekeeping genes 
(GUSB, SDHA, and  UBC).
For gene mutation analysis, DNA will be extracted from the fresh-frozen or formalin-
fixed paraffin-embedded (FFPE) tissue sections. PCR amplification of exons encoding 
the open reading frame of genes associated with KCOT will be carried out using nested 
primers prior to sequencing PCR products in both the sense and antisense directions.  
Identified mutations will be confirmed by an independent PCR and sequencing reaction. 
Potential Risks to Participants 
Information on potential risks to patients participating in this study is as follows:
•
Oral Examinations/Head and Neck Examination:  


Page 31 of 63
14 Oct 2016
The oral examination will involve procedures that are routinely performed in dental 
practice.  A licensed dentist/hygienist will perform the procedures. The risks from the 
oral examination include minor discomfort or minor pain during the procedures.
•
Biological Sample Collection:  
Urine (if female of child bearing potential) will be collected. This collection processes 
minimal risk to the patient.  
•
Blood Sampling Collection:
Peripheral blood sampling will be performed by a trained phlebotomist, nurse, dentist or 
physician utilizing standard venipuncture techniques.  
Patients may have some 
discomfort and/or bruising at the site of needle entry.  There is a very small risk of 
fainting.  Infection in the area of the needle insertion is rare.  Preventive measures will 
be used during sample collection to reduce the risk of these rare side effects.
•
GDC-0449 Administration: 
Vismodegib is a previously studied drug. Our knowledge of adverse events related to 
vismodegib results from clinical trials. Adverse reactions and the associated incidence 
related to vismodegib are documented. Participants will be closely monitored for 
previously-reported and unrecognized adverse events. Tumor growth in participants on 
the drug is possible; however, participants will be monitored with both clinical and 
radiographic examination to identify such growth. Participants on vismodegib might 
avoid surgery and the morbidity (i.e., loss of bone and teeth) associated with surgery.
GDC-0449 (Vismodegib) capsule is a Hh pathway inhibitor indicated for the treatment of 
adults with metastatic basal cell carcinoma, or with locally advanced basal cell 
carcinoma that has recurred following surgery or who are not candidates for radiation. 
The most common adverse reactions (incidence ≥ 10%) are muscle spasms, alopecia, 
dysgeusia, weight loss, fatigue, nausea, diarrhea, decreased appetite, constipation, 
arthralgias, vomiting and ageusia. In clinical trials, a total of 3 of 10 pre-menopausal 
women developed amenorrhea while receiving GDC-0449. Treatment-emergent Grade 
3 laboratory abnormalities observed in clinical trials were hyponatremia in 6 patients 
(4%), hypokalemia in 2 patients (1%), and azotemia in 3 patients (2%).
The safety and efficacy of vismodegib in pediatric patients has not been established. 
Studies in animals indicate that oral Hh pathway inhibitors pose a substantial risk of 
developmental defects during the post-natal period, which includes irreversible effects 
on growing teeth or bones and male reproductive organs. The occurrence of premature 
epiphyseal fusion has been identified on routine pharmacovigilance through literature 
review and from serious adverse events (SAEs) reported in an Investigator Sponsored 
Trial (IST) of pediatric patients receiving vismodegib therapy. In some cases, fusion 
progressed after drug discontinuation.
In this study, the safety and efficacy of oral GDC-0449 in the management of NBCCS-
associated KCOT and sporadic KCOT will be examined. The recommended dose is 
150mg taken orally once daily until disease progression or until unacceptable toxicity. 
The capsule has a pink opaque body and a grey opaque cap with “150 mg” printed on 
the capsule body and “Vismo” printed on the capsule cap in black ink. It can be taken 


Page 32 of 63
14 Oct 2016
with or without food and capsules should not be opened or crushed. If patients miss a 
dose, they will be advised not to make up that dose but instead to resume dosing with 
the next scheduled dose. 
Pregnancy status prior to the initiation of GDC-0449 will be verified with a serum 
pregnancy test. Male and female patients will be advised of the risks of embryo-fetal 
death and severe birth defects and the need for contraception during and after 
treatment.
In addition, patients must agree not to donate blood or blood products during the study 
and for 24 months after discontinuation of vismodegib.
If a patient experiences unacceptable drug toxicity, he/she will be allowed a treatment 
break lasting for at least one month, up to three months. If the patient is unable to 
resume treatment after an 3 month treatment break, he/she will be discontinued from 
the study.
A potential risk of treatment of KCOT with vismodegib is disease progression, i.e. tumor 
growth. Participants will be closely monitored with clinical and radiographic examination 
for evidence of disease progression. The natural history of KCOTs is that the tumors 
grow and expand slowly relative to the proposed examination schedule. Therefore, it is 
highly unlikely that unanticipated growth in participants on vismodegib would be 
encountered.
The potential benefit of treatment of KCOT with vismodegib is decreased tumor 
recurrence and reduced surgical morbidity. Currently the management of KCOT is 
surgical. The surgical options include:  1. resection, 2. enucleation with or without 
treatment of the bony cavity using tissue fixatives or liquid nitrogen, or 3. surgical 
decompression. The morbidity of surgical resection and enucleation involves the loss of 
bone and teeth. In some cases the sensory nerve in the proximity of the tumor is 
removed leaving the patient with paresthetia or anesthesia in the distribution of the face 
or tongue. Replacement of bone and teeth is extremely difficult and in many cases not 
possible. Decompression involves placement of a drain into the tumor cavity followed by 
irrigation of the bony cavity three times a day for 12 to 24 months. Often after this 
treatment eventual removal of the tumor is required. A potential benefit for participants 
treated with vismodegib is that they might avoid the morbidity associated with the 
above-described surgery. 
4.4.1 Phase 1: Screening  
Potential patients (10 with NBCCS-associated KCOT and 10 with sporadic KCOT, 
males and females, ≥18 years) will be recruited from the Department of Oral and 
Maxillofacial Surgery at NYU College of Dentistry, NYU Langone Medical Center and 
Bellevue Hospital, as all these institutions represent major referral sources for head and 
neck pathology. Patients will also be recruited from other private and academic oral and 
maxillofacial surgery practices both in the New York area and other parts of the country 


Page 33 of 63
14 Oct 2016
by referral.  Investigator will present this study during society meetings so that other 
surgeons can refer KCOT patients to this study. 
Before a patient’s participation in the study, the investigator will be responsible for 
obtaining written ICF from the patient, after adequate explanation of the aims, methods, 
anticipated benefits and potential risks of the study and before any protocol specific 
screening procedure is performed or the study drug is administered. The patient will be 
given ample time to consider the information provided and ask questions before giving 
written consent.
The acquisition of informed consent will be thoroughly documented in the patient’s chart 
and the informed consent form with be personally signed and dated by both the patient 
and the person who conducted the informed consent discussion. A patient will be 
considered enrolled in the study, once the informed consent form is signed. The original 
informed consent will be retained and a copy will be provided to the patient. The same 
process will be followed for the consenting for optional future genetic testing on blood 
and on the tumor. 
4.4.2 Baseline Visit
The following procedures will be performed at Baseline visit (study procedures and 
assessments during the baseline visit can be conducted over several visits until all 
inclusion/exclusion criteria are verified and patient is eligible to proceed with treatment 
(first study drug administration).

Serum Pregnancy Test (if female patient of child bearing potential):
o
Female patients of reproductive potential are required to use two forms of 
acceptable contraception during therapy and for 24 months after completing 
therapy. See appendix B for definition of reproductive potential and 
acceptable contraception. Male patients must use condoms at all times, 
even after a vasectomy, during sexual intercourse with female partners of 
reproductive potential during treatment with vismodegib and for 2 months 
after the last dose to avoid exposing a pregnant partner and unborn fetus to 
vismodegib.
o
If 7 days have passed between the patient’s enrollment in the study (date 
the ICF was signed) and the first study drug administration, the serum 
pregnancy test will be repeated.

Oral Cavity Assessment (soft & hard tissues, extraoral, head & neck)

Physical Exam 

Clinical Laboratories
o
Complete blood count, serum pregnancy test, serum chemistry, coagulation 
time, and liver function will be assessed: white blood count, hemoglobin, 
platelets, glucose, uric acid, calcium, phosphorus, sodium, potassium, 
chloride, alkaline phosphatase, albumin, alanine transaminase (ALT), 
aspartate transaminase (AST), BUN and creatinine
o
All laboratory results will be reviewed and the reports will be signed by the 
investigator. Any results considered to be of clinical significance must be 
dealt with and followed up as clinically appropriate. All laboratory results 
considered to represent an AE must be documented in the CRF. Repeat 
samples will be taken if required for clinical follow up or because the sample 
is lost or damaged. Any abnormal end of treatment clinical laboratory result 
of clinical significance must be repeated at regular intervals until it returns to 
normal, or until the investigator is satisfied that the abnormality is not 
related to the study drug and needs no further investigation.

withdrawn from the study immediately upon confirmation of pregnancy. These subjects 
will be required to return to the study site to undergo discontinuation visit assessments. 
In addition, any documented pregnancy will be tracked and followed through outcome. 
4.7
Study Discontinuation
The Genentech Study Center and the Principal Investigator have the right to terminate 
this study at any time.  Reasons for terminating the study may include the following:

The incidence or severity of adverse events in this or other studies indicates a 
potential health hazard to subjects

Subject enrollment is unsatisfactory

Data recording are inaccurate or incomplete

Study protocol not followed
Both the investigator and Genentech, Inc. reserve the right to terminate the study at any 
time.  Should this be necessary, both parties will arrange discontinuation procedures.  In 
terminating the study, both the investigator and Genentech, Inc. will assure that 
adequate consideration is given to the protection of the patients’ interests.  All patients 
will undergo an exit examination if the study is terminated prematurely.
Patient’s medical information obtained as a result of this study is considered confidential 
and disclosure to third parties other than those noted below is prohibited.  Patients will 
receive written copies of all laboratory data, and radiographs to bring to their health care 
provider.  All reports and communications relating to patients in this study will identify 
each patient only by their initials and number.  Medical information resulting from a 
patient’s participation in this study may be given to the patient’s personal physician or to 


Page 42 of 63
14 Oct 2016
the appropriate medical personnel responsible for the patient’s welfare.  Data generated 
as a result of this study are to be available for inspection on request by FDA or other 
government regulatory agency auditors, Genentech’s medical monitor (or designee), 
and the Institutional Review Board (IRB).
4.8
Statistical Methods
a. Analysis of the Conduct of the Study
Accrual rates and sampling bias will be determined by computing the recruitment rate 
from among those identified as eligible.
Retention and compliance will be evaluated as the proportion of completers at the four 
primary time points: after 6 and up to 12 months of treatment, and then 1 and 2 years 
after treatment. We will detail and tabulate reasons for loss to follow-up and relate 
retention to baseline age, KCOT severity and between NBCSS-associated and 
sporadic cohorts. 
b. Efficacy Analysis
i.
Primary Endpoint
The effect of GDC-0449 will be evaluated (at a significance level of 5% and controlling 
the false discovery rate) using Wilcoxon signed rank tests to compare the mean KCOT 
volume at baseline to those acquired at 6, 12, 24,36 and 48 months. These 
comparisons will also be accomplished using paired t-tests. 
ii. Subject population for this analysis. As a primary intention to treat (ITT) analysis, we 
will analyze data from all randomized subjects who complete Phase 1.  For these 
analyses, Phase 1 values will be substituted for missing observations. Should more 
than 20% of the data be missing at any observation interval, analysis of that interval will 
be abandoned. Deviations from this plan, for example, emergent interest in the analysis 
of the all-treated or protocol-compliant subjects, will be transparently pursued and 
reported. 
iii. Treatment of missing data. Two secondary effectiveness analyses will either carry 
the last observation forward into missing cells, or use maximum likelihood estimates of 
those values. We expect the best estimate of efficacy is likely to lie within the limits set 
by these conservative (ITT) and liberal (LOCF, ML) treatments of missing data.
iv. Secondary Endpoints
Secondary analysis will quantify the proportion of patients achieving minimal clinically 
significant changes in their tumors and comparing that to a theoretical expectation of 
5% improvement with a Fisher exact test, and the effect of the PTCH1 mutation on 
tumor volume reduction will be assessed with an independent samples t-test. These 
analyses will use the same population as the primary endpoint.
All analyses will be done using IBM SPSS Version 21.


Page 43 of 63
14 Oct 2016
v. Sample size determination. Twenty subjects will be recruited. Analysis of the primary 
endpoint is capable of detecting changes in tumor volume in the Wilcoxon tests of 
approximately 1.0 and .68 SD, assuming a 2-tailed type 1 error of 5% and power of 80% 
and then assuming either n=10 (separate analysis of the NBCSS-associated and 
sporadic cohorts) or n=20 (combined analysis of both cohorts), respectively (G*Power, 
v3.1).
c. Safety Analysis
All safety-related interventions, events, and findings will be summarized by incidence 
and duration and event classification. An adverse event will be considered treatment 
emergent if the onset date and time occur on or after the recorded clock time of the 
administration of study drug. Adverse events will be coded to preferred terms and 
system organ classes according to the Medical Dictionary for Regulatory Activities 
(MedDRA®). The severity of each adverse event will be determined from the World 
Health Organization (WHO) Toxicity Criteria or by protocol specified criteria. In addition, 
all adverse events will be assessed as to whether the onset of the event was related to 
the study drug or not and they will be followed to final resolution. Other safety 
assessments include vital signs, oral cavity examinations, and complete blood count. In 
the unlikely event that treatment is associated with increasing tumor size, tumor area, 
determined from panoramic radiographs acquired at each visit, will be compared to 
baseline.
4.9
Data Quality Assurance
Accurate, consistent, and reliable data will be ensured through the use of standard 
practices and procedures.

REPORTING OF ADVERSE EVENTS
5.1
Assessment of Safety
Specification of Safety Variables 
Safety assessments will consist of monitoring and reporting adverse events (AEs) and 
serious adverse events (SAEs) per protocol. This includes all events of death, and any 
study specific issue of concern.
Adverse Events
An AE is any unfavorable and unintended sign, symptom, or disease temporally 
associated with the use of an investigational medicinal product (IMP) or other protocol-
imposed intervention, regardless of attribution.
This includes the following:

AEs not previously observed in the subject that emerge during the protocol-
specified AE reporting period, including signs or symptoms associated with KCOT that 
were not present prior to the AE reporting period.

Complications that occur as a result of protocol-mandated interventions (e.g., 
invasive procedures such as cardiac catheterizations).
If applicable, AEs that occur prior to assignment of study treatment associated with 
medication washout, no treatment run-in, or other protocol-mandated intervention.
Preexisting medical conditions (other than the condition being studied) judged by the 
investigator to have worsened in severity or frequency or changed in character during 
the protocol-specified AE reporting period.
Serious Adverse Events
An AE should be classified as an SAE if the following criteria are met:

It results in death (i.e., the AE actually causes or leads to death).

It is life threatening (i.e., the AE, in the view of the investigator, places the subject 
at immediate risk of death. It does not include an AE that, had it occurred in a more 
severe form, might have caused death.).

It requires or prolongs inpatient hospitalization.

It results in persistent or significant disability/incapacity (i.e., the AE results in 
substantial disruption of the subject’s ability to conduct normal life functions).

It results in a congenital anomaly/birth defect in a neonate/infant born to a mother 
exposed to the IMP.

It is considered a significant medical event by the investigator based on medical 
judgment (e.g., may jeopardize the subject or may require medical/surgical intervention 
to prevent one of the outcomes listed above).


Page 45 of 63
14 Oct 2016
Data Safety Monitoring Plan

The principal investigator will be responsible for data and safety monitoring of this 
single site study.  Adverse events, serious adverse events, unanticipated problems, and 
subject status will be reviewed at least annually after enrollment begins.  Both the 
investigator and Genentech, Inc. reserve the right to terminate the study, if the 
incidence or severity of adverse events in this or other studies indicates a potential 
health hazard to subjects.  Should this be necessary, both parties will arrange 
discontinuation procedures.  
In terminating the study, both the investigator and 
Genentech, Inc. will assure that adequate consideration is given to the protection of the 
patients’ interests.  All patients will undergo an exit examination if the study is 
terminated prematurely.  Data safety monitoring summary will be submitted to the IRB 
at the time of annual continuation review.   
5.2
Methods and Timing for Assessing AND Recording Safety 
Variables
The investigator is responsible for ensuring that all AEs and SAEs that are observed or 
reported during the study are collected and reported to the FDA, appropriate IRB(s), 
and Genentech, Inc. in accordance with CFR 312.32 (IND Safety Reports). 
Adverse Event Reporting Period
The study period during which all AEs and SAEs must be reported begins after informed 
consent is obtained and initiation of study treatment and ends 30 days following the last 
administration of study treatment or study discontinuation/termination, whichever is 
earlier. After this period, investigators should only report SAEs that are attributed to 
prior study treatment. All AEs occurring from the start of study treatment through to 
study completion, whether or not they are related to the study, will be recorded in the 
subject chart. 
Assessment of Adverse Events
All AEs and SAEs whether volunteered by the subject, discovered by study personnel 
during questioning, or detected through physical examination, laboratory test, or other 
means will be reported appropriately. Each reported AE or SAE will be described by its 
duration (i.e., start and end dates), regulatory seriousness criteria if applicable, 
suspected relationship to the study drug (see following guidance), and actions taken.
To ensure consistency of AE and SAE causality assessments, investigators should 
apply the following general guideline:
Yes
There is a plausible temporal relationship between the onset of the AE and 
administration of vismodegib, and the AE cannot be readily explained by the subject’s 
clinical state, intercurrent illness, or concomitant therapies; and/or the AE follows a 
known pattern of response to vismodegib; and/or the AE abates or resolves upon 


Page 46 of 63
14 Oct 2016
discontinuation of vismodegib or dose reduction and, if applicable, reappears upon re-
challenge
No
Evidence exists that the AE has an etiology other than vismodegib (e.g., preexisting 
medical condition, underlying disease, intercurrent illness, or concomitant medication); 
and/or the AE has no plausible temporal relationship to vismodegib administration (e.g., 
cancer diagnosed 2 days after first dose of vismodegib).
Expected adverse events are those adverse events that are listed or characterized in 
the Package Insert or current Investigator’s Brochure. 
Unexpected adverse events are those not listed in the Package Insert or current 
Investigator’s Brochure or not identified. This includes adverse events for which the 
specificity or severity is not consistent with the description in the Package Insert or 
current Investigator’s Brochure. For example, under this definition, hepatic necrosis 
would be unexpected if the Package Insert or current Investigator’s Brochure only 
referred to elevated hepatic enzymes or hepatitis.
5.3
Procedures for Eliciting, Recording, and Reporting Adverse 
Events
Eliciting Adverse Events
A consistent methodology for eliciting AEs at all subject evaluation timepoints should be 
adopted. Examples of non-directive questions include: 

“How have you felt since your last clinical visit?”

“Have you had any new or changed health problems since you were last here?” 
Specific Instructions for Recording Adverse Events
Investigators should use correct medical terminology/concepts when reporting AEs or 
SAEs. Avoid colloquialisms and abbreviations.
a.
Diagnosis vs. Signs and Symptoms
If known at the time of reporting, a diagnosis should be reported rather than individual 
signs and symptoms (e.g., record only liver failure or hepatitis rather than jaundice, 
asterixis, and elevated transaminases). However, if a constellation of signs and/or 
symptoms cannot be medically characterized as a single diagnosis or syndrome at the 
time of reporting, it is acceptable to report the information that is currently available. If a 
diagnosis is subsequently established, it should be reported as follow-up information.
b.
Deaths
All deaths that occur during the protocol-specified AE reporting period (see Section 5.2), 
regardless of attribution, will be reported to the appropriate parties. When recording a 
death, the event or condition that caused or contributed to the fatal outcome should be 


Page 47 of 63
14 Oct 2016
reported as the single medical concept. If the cause of death is unknown and cannot be 
ascertained at the time of reporting, report “Unexplained Death”.
c.
Preexisting Medical Conditions
A preexisting medical condition is one that is present at the start of the study. Such 
conditions should be reported as medical and surgical history. A preexisting medical 
condition should be re-assessed throughout the trial and reported as an AE or SAE only 
if the frequency, severity, or character of the condition worsens during the study. When 
reporting such events, it is important to convey the concept that the preexisting 
condition has changed by including applicable descriptors (e.g., “more frequent 
headaches”).
d.
Hospitalizations for Medical or Surgical Procedures
Any AE that results in hospitalization or prolonged hospitalization should be 
documented and reported as an SAE. If a subject is hospitalized to undergo a medical 
or surgical procedure as a result of an AE, the event responsible for the procedure, not 
the procedure itself, should be reported as the SAE. For example, if a subject is 
hospitalized to undergo coronary bypass surgery, record the heart condition that 
necessitated the bypass as the SAE.
Hospitalizations for the following reasons do not require reporting:

Hospitalization or prolonged hospitalization for diagnostic or elective surgical 
procedures for preexisting conditions

Hospitalization 
or 
prolonged 
hospitalization 
required 
to 
allow 
efficacy 
measurement for the study or

Hospitalization or prolonged hospitalization for scheduled therapy of the target 
disease of the study.
e.
Pregnancy
If a female subject becomes pregnant while receiving the study drug or within 24 
months after the last dose of study drug, a report should be completed and 
expeditiously submitted to Genentech. If a male subject receiving study drug (or within 3 
month after the last dose of study drug) impregnates a female partner, then the female 
partner will be requested to provide informed consented to permit a report of the 
pregnancy to be completed and expeditiously submitted to Genentech.
Follow-up to obtain the outcome of the pregnancy should also occur. Abortion, whether 
accidental, therapeutic, or spontaneous, should always be classified as serious, and 
expeditiously reported as an SAE. Similarly, any congenital anomaly/birth defect in a 
child born to a female subject exposed to study drug should be reported as an SAE.
Additional information on any vismodegib-exposed pregnancy and infant will be 
requested by Roche Drug Safety at specific timepoints (i.e., after having received the 
initial report, at the end of the second trimester, 2 weeks after the expected date of 
delivery, and at 3, 6, and 12 months of the infant’s life).


Page 48 of 63
14 Oct 2016
f.
Post-Study Adverse Events
The investigator should expeditiously report any SAE occurring after a subject has 
completed or discontinued study participation if attributed to prior vismodegib exposure. 
If the investigator should become aware of the development of cancer or a congenital 
anomaly in a subsequently conceived offspring of a female subject who participated in 
the study, this should be reported as an SAE. 
g.
Reconciliation
The Sponsor agrees to conduct reconciliation for the product. Genentech and the 
Sponsor will agree to the reconciliation periodicity and format, but agree at minimum to 
exchange quaterly line listings of cases received by the other party. If discrepancies are 
identified, the Sponsor and Genentech will cooperate in resolving the discrepancies. 
The responsible individuals for each party shall handle the matter on a case-by-case 
basis until satisfactory resolution.  The sponsor shall receive reconciliation guidance 
documents within the “Activation Package.”
h. 
AEs of Special Interest (AESIs)
There are no Adverse Events of Special Interest (AESIs)for vismodegib. 
I. 
Instructions for Reporting Adverse Events
Serious Adverse Events Reporting
Investigators must report all SAEs and AESIs to Genentech within the timelines 
described below. The completed MedWatch/case report should be faxed immediately 
upon completion to Genentech Drug Safety at:
(650) 225-4682 or
 (650) 225-4630

Relevant follow-up information should be submitted to Genentech Drug Safety as 
soon as it becomes available.

Serious AE reports that are related to vismodegib and AEs of Special Interest 
(regardless of causality) will be transmitted to Genentech within fifteen (15) calendar 
days of the Awareness Date.
Non-Serious Adverse Events
Bluestone Center for Clinical Research will forward a copy of the Final Study Report to 
Roche upon completion of the Study.
Special Situations Reports
In addition to SAEs, pregnancy reports, and AESIs, the following Special Situations 
Reports should be collected and transmitted to Roche even in the absence of an 
Adverse Event within thirty (30) calendar days:

Data related to product usage during pregnancy or breastfeeding


Page 49 of 63
14 Oct 2016

Data related to overdose, abuse, misuse, inadvertent/erroneous administration, 
medication error or occupational exposure, with or without association with an 
AE/SAE unless otherwise specified in the protocol

Lack of therapeutic efficacy

Suspected Transmission of an Infectious Agent (STIAMP) by the study drug
–
Any organism, virus, or infectious particle (e.g., prion protein transmitting 
transmissible spongiform encephalopathy), pathogenic or non-pathogenic, is 
considered an infectious agent.  A transmission of an infectious agent may be 
suspected from clinical symptoms or laboratory findings that indicate an 
infection in a patient exposed to a medicinal product.  This term applies only 
when a contamination of the study drug is suspected.
MEDWATCH 3500a REPORTING GUIDELINES
In addition to completing appropriate patient demographic and suspect medication 
information, the report should include the following information within the Event 
Description (section 5) of the MedWatch 3500A form:

Protocol description (and number, if assigned)

Description of event, severity, treatment, and outcome if known

Supportive laboratory results and diagnostics

Investigator’s assessment of the relationship of the adverse event to each 
investigational product and suspect medication.
Follow-up Information
Additional information may be added to a previously submitted report by any of the 
following methods:

Adding to the original MedWatch 3500A report and submitting it as follow-up

Adding supplemental summary information and submitting it as follow-up with the 
original MedWatch 3500A form 

Summarizing new information and faxing it with a cover letter including patient 
identifiers (i.e. D.O.B. initial, patient number), protocol description and number, if 
assigned, brief adverse event description, and notation that additional or follow-up 
information is being submitted (The patient identifiers are important so that the new 
information is added to the correct initial report)
Occasionally Genentech may contact the reporter for additional information, 
clarification, or current status of the patient for whom an adverse event was reported. 
For questions regarding SAE reporting, you may contact the Genentech Drug Safety 
representative noted above or the MSL assigned to the study. Relevant follow-up 
information should be submitted to Genentech Drug Safety as soon as it becomes 
available and/or upon request.

RETENTION OF RECORDS
U.S. FDA regulations (21 CFR §312.62[c]) and the ICH Guideline for GCP (see Section 
4.9 of the guideline) require that records and documents pertaining to the conduct of 
clinical trials and the distribution of investigational drug, subject records, consent forms, 
laboratory test results, and medication inventory records, must be retained for 2 years 
after the last marketing application approval in an ICH region or after at least 2 years 
have elapsed since formal discontinuation of clinical development of vismodegib.  
All state and local laws for retention of records also apply. 
For studies conducted outside the United States under a U.S. IND, the Principal 
Investigator must comply with the record retention requirements set forth in the U.S. 
FDA IND regulations and the relevant national and local health authorities, whichever is 
longer.

RESPONSIBILITIES
7.1 Investigator Responsibilities
7.1.1 Compliance with Good Clinical Practice 
The Sponsor-Investigator will ensure this study is conducted in accordance with the 
basic principles of “Good Clinical Practice,” as outlined in 21 CFR 312, subpart D, 
“Responsibilities of Sponsors and Investigators,” 21 CFR, part 50, part 54, and part 56, 
as well as applicable requirements of the International Conference on Harmonization 
(ICH) Guideline of Good Clinical Practice (ICH E6) and the Health Insurance Portability 
and Accountability Act of 1996 (HIPAA).
7.1.2 Institutional Review Board (IRB) 
This protocol, any protocol amendments and any study related materials (such as 
advertisements, patient information sheets, or descriptions of the study used to obtain 
informed consent) will be submitted to the IRB.  Approval from the IRB must be 
obtained before starting the study and documented in a letter to the investigator 
specifying the protocol number, if applicable, protocol version, documents reviewed, 
and date on which the IRB granted the approval.  
All unexpected SAEs related to study participation will be reported to the IRB within 5 
business days.  
7.1.3 Informed Consent
Informed Consent for patients ≥ 18 years of age:
For inclusion of patients 18 years or older, the investigator will obtain written informed 
consent from each individual participating in this study after adequate explanation of the 
aims, methods, objectives, and potential hazards of the study and prior to undertaking 


Page 52 of 63
14 Oct 2016
any study-related procedures.  The investigator will utilize an IRB-approved consent 
form.  
Each ICF will be signed and dated by the individual participating in the study and the 
person obtaining the consent.  By signing the ICF, the patient agrees to complete all 
evaluations unless the patient withdraws consent or is terminated from the study for any 
reason.
As part of the informed consent, the investigator will obtain HIPAA compliant 
authorization from patients to use and disclose relevant protected health information 
(PHI) and permission for authorized representatives of Genentech Inc., or regulatory 
authorities including the FDA, to review in confidence any records identifying patients in 
the clinical study.
Recruitment efforts may precede obtaining informed consent; however, informed 
consent must be obtained prior to any protocol specific procedures being performed.
The investigator will communicate any new information on safety to patients who 
consent to participate in this study in accordance with IRB requirements.  The ICF will 
be updated, if necessary. 
7.1.4 Confidentiality
The investigator will assure that patients’ anonymity will be strictly maintained and that 
their identities will be protected from unauthorized parties.  Only patient initials and an 
identification code (i.e., not names) will be recorded on any form submitted to the 
sponsor or IRB.  
The investigator agrees that all information received from Genentech, Inc., including but 
not limited to the Investigator’s Brochure, the study drug, and any other study 
information, are the sole and exclusive property of Genentech Inc.  This information is 
not to be disclosed to any third party (except employees or agents directly involved in 
the conduct of the study or as required by law) without prior written consent from 
Genentech Inc.  
The investigator further agrees to take all reasonable precautions to prevent the 
disclosure by any employee or agent of the study site to any third party or otherwise into 
the public domain.
7.1.5 Study Files and Retention of Records
The investigator will maintain adequate and accurate records that fully document the 
conduct of the study and enable study data to be verified.  These documents should be 
classified into separate categories:  1) investigator’s study file (regulatory binder) and 2) 
patient clinical source documents.

The investigator’s study file (regulatory binder) includes the original protocol, 
protocol amendments, CRFs and query forms, IRB approval with correspondence, 


Page 53 of 63
14 Oct 2016
approved informed consent forms, drug records, staff curriculum vitae (CV) and 
authorization forms, and other appropriate documents and correspondence.

Patient clinical source documents include, but are not limited to, the patient’s 
medical/dental records, laboratory reports, radiographs, pathology and special 
assessment reports, consultant letters, screening and enrollment log, as applicable.  
The investigator will make the source documents for this study available for inspection 
to Genentech, Inc. or its representatives, or to regulatory or health authority inspectors.  
The investigator will retain all study documents for at least two years after the last 
approval of a marketing application in an International Conference on Harmonisation 
(ICH) region (i.e., United States, Europe, or Japan), and until there are no pending or 
contemplated marketing applications in an ICH region.  If no application is filed or if the 
application is not approved for such indication, the investigator will retain all study 
documents for at least two years after the investigation is discontinued and regulatory 
authorities have been notified.  
If no application is filed or if the application is not approved for such indication, the 
investigator will retain all study documents for at least two years after the investigation is 
discontinued and regulatory authorities have been notified.  The investigator may retain 
documents longer if required by applicable regulatory requirements or by agreement 
with Genentech, Inc.
7.1.6 Case Report Forms 
The investigator is responsible for the completeness and accuracy of information 
collected on the CRFs for each individual enrolled.  The investigator will review and 
approve all CRFs; document the reason that a patient withdraws from the study on the 
appropriate CRF and attempt to obtain termination assessments; and continue follow-up 
to document the outcome of any adverse event.

Women of child-bearing potential must use two methods of acceptable contraception 
including one highly effective method and a barrier method during Erivedge therapy and 
for 9 months after the final dose.
Acceptable forms of barrier contraception include the following:

Latex, non-latex, or any other male condom (always used with spermicide)

Diaphragm (always used with spermicide)
Acceptable forms of secondary contraception, when used with a barrier method, include the 
following:

Combination hormonal contraceptives, hormonal patch, or hormonal intramuscular 
contraceptives (subcutaneous hormonal implant, medroxyprogesterone acetate depot)

Tubal sterilization
Other acceptable forms include the following:

100% commitment to abstinence from sexual intercourse (for medical or personal 
reasons)

1. About volunteering for this research study
You are being invited to take part in a research study. Your participation is voluntary which means you 
can choose whether or not you want to take part in this study.
People who agree to take part in research studies are called “subjects” or “research subjects”. These 
words are used throughout this consent form.  Before you can make your decision, you will need to know 
what the study is about, the possible risks and benefits of being in this study, and what you will have to 
do in this study. You may also decide to discuss this study and this form with your family, friends, or 
doctor.  If you have any questions about the study or about this form, please ask us. If you decide to take 
part in this study, you must sign this form. We will give you a copy of this form signed by you for you to 
keep.
2. What is the purpose of this study?
The purpose of this study is to determine how well a daily dose of 150 mg of Erivedge (vismodegib) 
reduces Keratocystic odontogenic tumor (KCOT) size, and to evaluate the safety of this dose. The 
keratocystic odontogenic tumor is an aggressive benign developmental tumor.  
Erivedge is Food and Drug Administration (FDA)-approved for use in adults with a specific type of skin 
cancer. However, the drug is experimental for patients with KCOT because it has not been FDA-
approved for the treatment of KCOT.
You are being invited to participate in this study because you have KCOT.

3. How long will I be in the study? How many other people will be in the 
study?
This is a single-site study which will take place at the NYU Bluestone Center for Clinical Research. We 
expect to screen about 40 subjects in order for 20 subjects to receive the investigational product in this 
study. 
It is expected that your participation in the study will last approximately 3 years. This time includes one 
year of treatment with Erivedge and two years of follow-up.
4. What will I be asked to do in the study?
This study involves one year of treatment with Erivedge (150 mg/day) plus two years of follow-up. The 
first study visit may take place all at once or over the course of a few days. At this visit, we will make sure 
you are eligible to participate in the study and ask you to complete some baseline procedures.
During the second phase of the study (treatment), we will ask you to attend a study visit once a month for 
a year (12 visits total) while you are taking 150 mg/day of Erivedge. If you are not able to tolerate the 
drug due to the side effects or if the study investigator thinks it is in your best interest to temporarily stop 
taking the drug, you will be given a 1-3 month treatment break. If, after 3 months, you are not able to 
resume taking the study drug, you will be discontinued from the study.
During the third phase of the study (post-treatment), we will ask to you attend study visits at 1, 2, 3, and 7 
months, and 1 and 2 years post-treatment. 
The procedures which will be performed at each visit are explained in detail below:
Phase 1: Screening
Baseline Visit:
The following procedures may take place all on one day or on separate days. In total, the procedures are 
expected to take approximately 8 hours.

You will be asked to read and sign this informed consent form.

We will collect demographic information, and review your medical and dental history, 
medications, and medical records.

We will record your height and weight, and take vital signs (blood pressure, heart rate, and 
temperature).

If you are a female of childbearing potential, you will be asked to have a serum pregnancy test. 
No additional blood will be taken for this test. If there are at least 7 days between the date you 
sign this informed consent form and the date which you are first given the study drug, the serum 
pregnancy test will be repeated. If a second test is required, a blood draw of approximately 1.5-2 
teaspoons (7-10mL) will be performed.

A member of the study team will perform an exam of your head, neck, mouth, and teeth.

A member of the study team will perform a physical exam, including an examination of your 
cardiovascular (heart and blood circulation), pulmonary (lungs), abdomen and nervous systems.

Approximately 4 teaspoons (20mL) of blood will be drawn for clinical laboratories. If any abnormal 
results are found, the study investigator may repeat this procedure for safety reasons.

Page 3 of 13

If you give us permission to use your blood for future genetic testing related to KCOT, we will 
draw an additional 1.5-2 teaspoons (7-10mL) of blood. You do not need to give us permission to 
perform this procedure in order to participate in this study.

If you did not previously have a biopsy of your tumor, or the tissue is no longer available, one will 
be performed as part of your standard of care. Biopsy will be done regardless of participation in 
this study; however, we will use the results of the biopsy for this study as well as ask for your 
permission to store leftover tissue for optional future genetic analysis. If you have multiple 
KCOTs, it is possible that more than one biopsy will need to be performed. This tissue 
sample/biopsy will be used to confirm KCOT diagnosis as well as for a genetic analysis of the 
tumor.

You will be asked to have a panoramic radiograph and a volumetric CT scan as part of your 
regular care (regardless of your participation in this study).  We will use and store these images 
for the purpose of this study. No additional scans will be performed for research purposes.

If you have nevoid basal cell carcinoma syndrome (NBCCS) associated KCOT, a member of the 
study team will perform a complete skin examination. NBCCS is a hereditary condition 
characterized by multiple basal cell skin cancers.  Photographs will be taken of any suspicious 
lesions. Your face will not be visible in any of these photographs.  You will be referred to a 
dermatologist if you have any suspicious lesions as per standard of care.

After all assessments have been completed and it is confirmed that you are eligible for the study, 
you will be given the first dose (150 mg) of study drug. You will be asked to stay at the study site 
for 6 hours for monitoring after taking the drug for the first time. You will then be given enough 
study drug to last you until the next visit, and be asked to take 150 mg by mouth once a day. 
o
The capsule may be taken with or without food, and should be taken whole. 
o
Do not open or crush the capsule.
o
If you miss a dose of the study drug, do not make up the missed dose. Resume taking the 
drug at the next schedule dose.

You will be given the following reminders:
o
Females will be required to use two forms of contraception (one barrier method and one 
secondary method) during the entire course of the study and 24 months after 
discontinuation of study drug. Acceptable forms of barrier contraception are: latex, non-
latex or any other male condom used with spermicide; or diaphragm used with 
spermicide. Acceptable forms of secondary contraception are: combination hormonal 
contraceptives, hormonal patch, or hormonal intramuscular contraceptives (subcutaneous 
hormonal implant, medroxyprogesterone acetate depot); or tubal sterilization. Another 
acceptable form of contraception is a 100% commitment to abstinence from sexual 
intercourse for the entire duration of the study.
o
Males will be required to use condoms at all times with female partners of reproductive 
potential during treatment and for 3 months after the last treatment.
o
Do not donate blood or blood products while taking the study drug, or for at least 24 
months after stopping the study drug.
o
Notify the study team if you experience any changes in your health or if you or a partner 
becomes pregnant.
Phase 2: Treatment
1 Month, 3 Months, 6 Months, and 1 Year (+/- 7 days):
Each of these visits is expected to take approximately 2 hours.

We will review your medical and dental history and medications to make sure you are still eligible


Arthralgias (joint pain)

Vomiting

Ageusia (loss of taste)


Approved For Period: 11/8/2016 - 10/3/2017
Study #: 15-00254
Version date: October 20, 2016
Page 7 of 13
Other potential side effects of Erivedge are:

Amenorrhea in pre-menopausal women (loss of menstrual period)

Hyponatremia (low sodium in the blood)

Hypokalemia (low potassium in the blood)

Azotemia (high levels of nitrogen-containing compounds in the blood, such as urea and creatine)
Premature fusion of the epiphyses (the end part of the long bone) has been reported in pediatric patients 
exposed to vismodegib. In some cases, fusion progressed after drug discontinuation.
Other Risks
Some of the procedures performed in the study carry certain risks, which are listed below.
Oral exam: There is a small risk of minimal pain or discomfort during the oral exam.
Blood draws: Blood draws will be conducted according to standard methods by a trained phlebotomist, 
nurse, dentist or physician. There may be some discomfort and/or bruising at the site of needle entry. 
There is a very small risk of fainting. Infection in the area of the needle insertion is rare. Preventive 
measures will be used during sample collection to reduce the risk of these rare side effects.
It is possible that this research may involve risks which are currently unforeseeable.
Panoramic radiograph and a volumetric CT scan risk: Because these imaging procedures are done as 
part of your routine care and regardless of your participation in this study, the doctor ordering these 
images or technologist performing the procedures will explain the risks of these procedures to you.
Genetic testing risk
A new Federal law, called the Genetic Information Nondiscrimination Act (GINA), generally makes it 
illegal for health insurance companies, group health plans, and most employers to discriminate against 
you based on your genetic information. This law generally will protect you in the following ways:

Health insurance companies and group health plans may not request your genetic information 
that we get from this research.

Health insurance companies and group health plans may not use your genetic information when 
making decisions regarding your eligibility or premiums.

Employers with 15 or more employees may not use your genetic information that we get from this 
research when making a decision to hire, promote, or fire you or when setting the terms of your 
employment.
All health insurance companies and group health plans must follow this law by May 21, 2010. All 
employers with 15 or more employees must follow this law as of November 21, 2009.
Be aware that this new Federal law does not protect you against genetic discrimination by companies 
that sell life insurance, disability insurance, or long-term care insurance.
6. Can I be in the study if I am pregnant or breastfeeding?
Because taking part in this study may harm an embryo, fetus, or breastfeeding baby, you should not 
become pregnant, breastfeed a baby, or father a child while participating in this study and for 24 months 
after discontinuation of study drug. Other risks may not yet be known.

Page 8 of 13
If you are currently pregnant or breastfeeding, you will not be able participate in the study. You should 
not become pregnant while you are participating in this study. If you are able to become pregnant, you 
will be required to use two forms of contraception (one barrier method and one secondary method) 
during the entire course of the study. Acceptable forms of barrier contraception are: 

latex, non-latex or any other male condom used with spermicide

diaphragm used with spermicide. 
Acceptable forms of secondary contraception are: 

combination hormonal contraceptives, 

hormonal patch

or hormonal intramuscular contraceptives (subcutaneous hormonal implant, 
medroxyprogesterone acetate depot)

tubal sterilization. 
Another acceptable form of contraception is a 100% commitment to abstinence from sexual intercourse 
for the entire duration of the study. 
If you become or you think you have become pregnant during the study, you must tell the principal 
investigator right away and must tell your obstetrician or other health care provider caring for you during 
your pregnancy that you took part in this study.  If you become pregnant, you will have to stop taking part 
in the study for safety reasons.  The principal investigator may ask you to provide information about the 
outcome of your pregnancy and the health of your baby.
Note to Men 
Because the effect of participating in this study on sperm are unknown, you will be required to use a 
condom (even if you have had a vasectomy) with spermicide during sexual intercourse with female 
partners of reproductive potential throughout the study and for 3 months after the end of study treatment.
If your partner becomes or thinks she may have become pregnant during the time you are in the study, 
you must tell the principal investigator right away. The principal investigator may ask for your partner’s 
permission to collect information about the outcome of her pregnancy and the health of her baby.  You 
will be given a contact form to share with your partner so that she can reach out to the study team if she 
is interested in providing information about her pregnancy and the health of her baby.  By sharing the 
contact form with your partner, your partner will become aware of your participation in this study.  If your 
partner chooses to provide her and her baby’s health information, she will be asked to sign a consent 
form before this information is collected.
7. What if new information becomes available?
During the course of this study we may find more information that could be important to you.  This 
includes information that might cause you to change your mind about being in the study.  We will notify 
you as soon as possible if such information becomes available.
8. What are the possible benefits of the study? 
It is possible that some study subjects who receive Erivedge may experience an improvement in their 
KCOT while taking Erivedge during the study. However, if you receive such benefit, because Erivedge is 
not FDA-approved for KCOT, your doctor cannot prescribe it after you finish the study.  Also, you may 
not get any benefit from being in this research study. Others with KCOT may benefit in the future from 
what we learn in this study.
