Brief summary:
This open-label, multicenter, non-randomized study provided continued access to vemurafenib for eligible participants with BRAF V600 mutation-positive malignancy, who were previously enrolled and treated in an antecedent vemurafenib protocol and did not meet the protocol's criteria for disease progression, or were treated beyond progression and were still deriving clinical benefit (as assessed by investigator), and may have therefore potentially benefited from continued treatment with vemurafenib. Participants received treatment with oral vemurafenib at 960 milligrams (mg) twice daily (BID), 720 mg BID, or 480 mg BID, depending on the last dose in the antecedent protocol. Treatment continued until progression of disease or as long as the participant was deriving clinical benefit, as judged by the investigator (case-by-case decision with approval of the Medical Monitor), death, withdrawal of consent, unacceptable toxicity, loss to follow-up, or decision of the Sponsor to terminate the study, whichever occurred first.

Detailed description:

Arms:
arm 1: Participants received oral vemurafenib at 480 mg BID, depending on the last dose in the antecedent protocol until progression of disease or as long as the participant is deriving clinical benefit, as judged by the investigator, death, withdrawal of consent, unacceptable toxicity, loss to follow-up, or decision of the sponsor to terminate the study, whichever occurs first. arm 2: Participants received oral vemurafenib at 720 mg BID, depending on the last dose in the antecedent protocol until progression of disease or as long as the participant is deriving clinical benefit, as judged by the investigator, death, withdrawal of consent, unacceptable toxicity, loss to follow-up, or decision of the sponsor to terminate the study, whichever occurs first. arm 3: Participants received oral vemurafenib at 960 mg BID, depending on the last dose in the antecedent protocol until progression of disease or as long as the participant is deriving clinical benefit, as judged by the investigator, death, withdrawal of consent, unacceptable toxicity, loss to follow-up, or decision of the sponsor to terminate the study, whichever occurs first.

Interventions: intervention 1: Vemurafenib
Intervention descriptions: intervention 1: Vemurafenib was given based on the last dose of the antecedent study (minimum 480 mg orally BID).

PROTOCOL AMENDMENT, VERSION 5:
RATIONALE
Protocol GO28399 has been amended to remove the Roche-designated central 
pathology laboratory because cuSCC is an identified risk that no longer requires further 
evaluation by an independent central pathology review.  Changes to the protocol are 
summarized below:

Safety follow-up visits at 3 and 6 months have been removed because secondary 
malignancies are no longer characterized as an important safety concern
(Sections 1.3, 3.1.1, 4.4.2, 4.5.1, 4.5.2, 4.5.3, 5.1.1, and 5.1.2.3). 

End of study safety follow up and dermatological evaluations have been updated to 
assessment until 28 days after the last dose of study drug (Sections 3.3, 4.5.1.9, 
and 5.1.2.3).

Follow-up for new primary malignancies has been updated to per investigator’s 
discretion (Section 4.4.2).
Additional changes to the protocol, along with a rationale for each change, are 
summarized below:

Additional new safety information, including acute kidney injury and Dupuytren’s 
contracture, has also been added per the current Vemurafenib Investigator’s 
Brochure (Section 1.2.1.5).

Study drug storage details have been referred to the study drug label 
(Section 4.3.1.1).

Adverse events of special interest and the reporting language have been clarified 
(Sections 5.2.3 and 5.4.2).

Section 5.2.4 (Selected Adverse Events) has been deleted and information from that 
section is consolidated in Section 5.3.5.9 (Worsening of Malignancy).

Adverse event reporting has been clarified (Section 5.3.1).

Persistent adverse event reporting has been clarified (Section 5.3.5.3).

The reporting of the term “sudden death” has been updated to also require the 
presumed cause of death (Section 5.3.5.7).

Event reporting for hospitalization has been clarified (Section 5.3.5.10).

Language has been revised to account for the fact that some sites may not allow 
follow-up on partner pregnancies (Section 5.4.3.2).

Reporting of pregnancy in a partner of a male patient has been clarified to when 
permitted by site (Section 5.4.3.2).

Follow up of patients after an adverse event and reporting of adverse events after 
the reporting period have been clarified (Sections 5.5 and 5.6).

Manual signature page has been removed because it is no longer needed given the 
use of an electronic signature stamp on the cover page.

Objectives
Primary Objective
The primary objective of this study is to provide continued access to vemurafenib for eligible 
patients with BRAFV600 mutationpositive malignancy who were previously treated in an 
antecedent vemurafenib protocol and did not meet the protocol’s criteria for disease progression 
or are being treated beyond progression and still deriving clinical benefit, as assessed by 
investigator, and may potentially benefit from continued treatment with vemurafenib.
Secondary Objective
The secondary objective is to collect and describe safety and tolerability data for patients who 
continue vemurafenib treatment in this extension (rollover) study.
Study Design
Description of Study
This is an open-label, multicenter, non-randomized study to provide continued access to 
vemurafenib for eligible patients with BRAFV600 mutationpositive malignancy who were 
previously enrolled and treated in an antecedent vemurafenib protocol and did not meet the 
protocol’s criteria for disease progression or are being treated beyond progression and still 
deriving clinical benefit (as assessed by the investigator) and may therefore potentially benefit 
from continued treatment with vemurafenib.  The maximum number of days between the last 
dose of study drug in the antecedent protocol and first dose in this extension (rollover) study 
will be 15 days.  Results of the study completion visit or other visit in the antecedent protocol 
may be used as screening/baseline for this extension (rollover) study.  Screening/baseline is 
combined into one visit if completed within time intervals, as specified in the protocol. The first 
vemurafenib treatment in the extension (rollover) study will be recorded as Cycle 1, Day 1.  
Patients will receive treatment with oral vemurafenib at 960 mg twice daily (BID), 720 mg BID, 
or 480 mg BID, depending on the last dose in the antecedent protocol.  Treatment will continue 
until progression of disease or as long as the patient is deriving clinical benefit, as judged by the 
investigator (case-by-case decision with approval of the Medical Monitor), death, withdrawal of 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
12
consent, unacceptable toxicity, loss to follow-up, or decision of the Sponsor to terminate the 
study, whichever occurs first.
One cycle is defined as 28 days.  Clinic visits will occur on Day 1 of Cycles 17 and on Day 1 of 
every other cycle through Cycle 15.  Then, for patients still receiving treatment, clinic visits will 
occur on Day 1 of every third cycle (i.e., screening/baseline and Day 1 of every third cycle from 
Cycle 18 for patients with 17 cycles of vemurafenib on an antecedent study) until 
unacceptable toxicity or disease progression, as defined by the investigator.  In patients with 
measurable disease, tumor assessments will be conducted for purposes of evaluating whether 
treatment should be discontinued via routine tumor assessments (computed tomography 
[CT]/magnetic resonance imaging) consistent with institutional standards of care, as outlined in 
the Schedule of Assessments.
Tumor assessments as specified and conducted in the antecedent protocol, including any 
evaluable and measurable disease, will have been documented at screening in the antecedent 
protocol.  In the extension (rollover) study, tumor assessments, including radiological tumor 
assessments of chest, abdomen, pelvis for measuring extent or progression of disease 
(CT scan is the preferred method) will be done at the discretion of the investigator according to 
local institutional standard of care for purposes of evaluating whether treatment should be 
discontinued.  
Safety evaluations will also be conducted during the study.  Safety evaluations will begin on 
Day 1 of the study and will continue throughout the study until 28 days after the last dose of 
study drug, withdrawal of consent, initiation of non-protocol therapy, death, or loss to follow-
up, whichever is earliest.  Adverse events related to the study medication will be monitored until 
resolution.  The tolerability and toxicity (safety) profile of vemurafenib will be evaluated using the 
National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), 
Version 4.0.
Target Population
The target population includes patients with BRAFV600 mutationpositive malignancy 
(including metastatic melanoma or other cancer types) who were previously enrolled and 
treated in an antecedent vemurafenib protocol and did not meet the protocol’s criteria for 
disease progression or are being treated beyond progression and still deriving clinical benefit, 
as assessed by investigator and may potentially benefit from receiving continued treatment with 
vemurafenib.  Patients with malignant tumor types other than malignant melanoma harboring a 
V600-activating mutation of BRAF who have no acceptable standard treatment options will also 
be allowed to participate in the trial.
Inclusion Criteria
A patient may be included if he or she meets all of the following criteria:
Disease-Specific Inclusion Criteria:
1.
BRAFV600 mutation-positive malignancy
2.
Prior eligibility for and received study treatment on an antecedent vemurafenib 
protocol
3.
Ability to begin treatment in the extension (rollover) protocol within 15 days following the 
last day of the study in the antecedent protocol
General Inclusion Criteria:
1.
Signed Informed Consent Form(s)
2.
Female patients of childbearing potential and male patients with partners of 
childbearing potential must agree to always use two adequate methods of contraception 
including at least one method with a failure rate of 1% per year during the course of 
this study and for at least 6 months after completion of study treatment.

Females of childbearing potential are defined as sexually mature women without 
prior hysterectomy who have had any evidence of menses in the past 12 months.  
In order to be considered not of childbearing potential, amenorrhea for a period of 
12 months or longer must have occurred in the absence of chemotherapy, anti-
estrogen therapy, or ovarian suppression.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
13

Effective forms of contraception include surgical sterilization, a reliable barrier 
method with spermicide, birth control pills, contraceptive hormone implants, or 
vasectomized partner.
3.
Negative serum pregnancy test within 7 days prior to commencement of dosing in 
women of childbearing potential; women of non-childbearing potential may be included 
if they are either surgically sterile or have been naturally menopausal for 1 year.  
Women of non-childbearing potential need not undergo the pregnancy test.
Exclusion Criteria
Patients who meet any of the following criteria will be excluded from study entry:
1.
Adverse event requiring discontinuation of vemurafenib in the antecedent protocol
2.
Progressive disease during the antecedent protocol.  If approval to treat beyond 
progression was already given in the antecedent protocol, the patient may roll over into 
the current protocol without Sponsor’s approval.  Under special circumstances, when it 
is felt that the patient may clinically benefit from continued therapy with vemurafenib,
enrollment into this protocol and dosing beyond progression may be considered if it is 
judged by the investigator, in consultation with the Sponsor, to be in the best interest of 
the patient.  All such cases will require approval of the Sponsor before enrolling the 
patient into this protocol.
3.
Meeting any of the following exclusion criterion of the antecedent study at the time the 
patient is considered for the extension (rollover) study:

Current, recent (within 28 days prior to Day 1), or planned use of any anti-tumor 
therapy outside of this study

Any other serious concomitant medical conditions that, in the opinion of the 
investigator, would compromise the safety of the patient or compromise the patient’s 
ability to participate in the study

History of malabsorption or other clinically significant metabolic dysfunctions

History of clinically significant cardiac or pulmonary dysfunction as specified in 
antecedent study
Length of Study
Treatment will continue until disease progression (as defined by investigator) or as long as the 
patient is deriving clinical benefit, as assessed by investigator, if treated beyond progression 
(case-by-case decision discussed and approved by the Medical Monitor), death, withdrawal of 
consent, unacceptable toxicity, loss to follow-up, or decision of the Sponsor to terminate the 
study, whichever occurs first.
End of Study
The study will end when all enrolled patients have discontinued study treatment and have been 
followed for safety assessment until 28 days after the last dose of study drug, death, 
withdrawal of consent, loss to follow-up, or if the Sponsor has decided to terminate the study, 
whichever occurs first.

BACKGROUND
1.1
BACKGROUND ON BRAFV600-POSITIVE MALIGNANCY 
BRAF is a human gene that makes a protein called B-Raf.  The B-Raf protein is involved 
in sending signals inside cells, which are involved in directing cell growth. 
Some mutations in the BRAF gene result in constitutively activated BRAF proteins, 
which can cause cell proliferation in the absence of growth factors that would normally 
be required for proliferation.  In 2002, the BRAF gene was shown to be mutated in 
human cancers (Davies et al. 2002).  Specifically, oncogenic mutations in BRAF kinase, 
predominantly V600E, have been observed in approximately 8% of all solid tumors, 
including 50% of metastatic melanomas, 30% to 70% of thyroid carcinomas, 30% of 
ovarian carcinomas, and 10% of colorectal carcinomas  (Davies et al. 2002; 
Fransen et al. 2004; Garnett and Marais 2004; Libra et al. 2005).
Vemurafenib (Zelboraf) (Zelboraf [vemurafenib] U.S. Package Insert), a low molecular 
weight, orally available inhibitor of some mutated forms of BRAF serine-threonine kinase, 
including BRAFV600E, was approved by the U.S. Food and Drug Administration (FDA) on 
17 August 2011 for the treatment of patients with unresectable or metastatic melanoma 
with the BRAFV600E mutation as detected by an FDA-approved test 
(Zelboraf [vemurafenib] U.S. Package Insert).  Vemurafenib was approved in Europe on 
17 February 2012 as monotherapy for the treatment of adult patients with 
BRAFV600 mutationpositive unresectable or metastatic melanoma.  Vemurafenib is also 
approved or has been submitted for approval in other countries.  Vemurafenib approval 
was based primarily on Study NO25026, an international, randomized, open-label trial in 
patients with previously untreated metastatic or unresectable melanoma with the 
BRAFV600E mutation, as detected by the cobas4800 BRAFV600 Mutation Test (Roche 
Molecular Systems, Inc.).  
1.2
ROLE OF BRAF KINASE IN MELANOMA
Recent advances in understanding of the biology of melanoma have identified the role of 
BRAF kinase.  Mutated BRAF dimers constitutively activate the mitogen-activated 
protein kinase (MAPK) pathway leading to the generation of transcriptional signaling that 
promotes tumor growth.  BRAF mutations have been identified in 50% to 68% of 
metastatic melanomas, specifically melanomas that arise from intermittent sun-exposed 
skin (e.g., superficial spreading and nodular melanomas [Maldonado et al. 2003; 
Beeram et al. 2005; Curtin et al. 2005; Lang and Mackie 2005]).  BRAF mutations are 
uncommon in acral, mucosal, and uveal melanomas.  In addition, BRAF mutations are 
common in benign nevi, suggesting that they are an early event in melanoma 
oncogenesis.  About 90% of the BRAF mutations seen in metastatic melanoma occur in 
codon V600, and more than 90% of the V600 mutations involve the substitution of valine 
for glutamate at amino acid 600 of the BRAF kinase (i.e., V600E; 1799 TA 
[Catalogue of Somatic Mutations in Cancer (COSMIC)]).  Other uncommon variants 
such as V600K, V600R, and V600D (in order of decreasing frequency) have also been 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
18
identified, primarily in melanoma.  Nonclinical data indicate that these variant mutations, 
like V600E, result in constitutive activation of the BRAF kinase.  Most of the transforming 
activity of BRAFV600 is thought to occur through the constitutive activation of the MAPK 
pathway (Gray-Schopfer et al. 2007).  Depletion of messenger RNA that codes for 
mutated BRAF by small interfering RNA leads to growth inhibition of melanoma cell lines 
in vitro (Sumimoto et al. 2004).  This has led to the development of agents that can 
inhibit mutated BRAF kinase as well as tests to identify V600 mutations (Flaherty 2006; 
Ascierto et al. 2010; Vultur et al. 2011).

Vemurafenib (RO5185426) BRAF Inhibitor
Vemurafenib is a low molecular weight, orally available inhibitor of some mutated forms 
of BRAF serine-threonine kinase, including BRAFV600E.  See the Vemurafenib 
Investigator’s Brochure (IB) for additional details.

Nonclinical Metabolism and Pharmacokinetics 
Nonclinical metabolism and pharmacokinetic (PK) information is presented in the 
Zelboraf[vemurafenib] U.S. Package Insert and the Vemurafenib IB.
1.2.1.3
Clinical Pharmacokinetics of Vemurafenib
The clinical pharmacokinetics of vemurafenib are based on data available from 
six studies in patients who received the commercial formulation: PLX06-02, the initial 
Phase I dose-escalation study to determine the maximum tolerated dose (MTD): 
Study NP22676, a cytochrome P450 metabolism study in patients with BRAFV600E
mutationpositive Stage IV melanoma; Study NP25158, a mass-balance study in 
patients with BRAFV600 mutationpositive Stage IV melanoma; Study NP25163, a 
dose-escalation study in patients with BRAFV600E mutationpositive unresectable 
Stage IIIc or Stage IV melanoma; Study NP22657, a Phase II, open-label study in 
patients with BRAFV600E mutationpositive Stage IV melanoma, in which the effects of 
vemurafenib on the QT interval were evaluated; and Study NO25026, a Phase III, 
randomized controlled study in patients with BRAFV600E mutationpositive unresectable 
Stage IIIc or IV melanoma.  Detailed descriptions of the design and PK results for each 
of these studies are provided in the Vemurafenib IB.
On the basis of dose-limiting toxicities reported at the 1120-mg twice daily (BID) dose 
level in Study PLX06-02, the 960-mg BID dose was considered the MTD and selected 
for use in all subsequent clinical trials, including the Phase I (Study PLX06-02; 
Vemurafenib IB; Flaherty et al. 2010) treatment-extension cohorts, as well as the 
aforementioned clinical pharmacology studies, and the Phase II (Study NP22657; 
Vemurafenib IB; Sosman et al. 2012) and Phase III (Study NO25026; Vemurafenib IB;

Chapman et al. 2011) studies in patients with unresectable Stage IIIc or metastatic 
melanoma.
Population PK analysis with the use of pooled data from 458 patients estimated the 
median of the steady-state maximum plasma concentration (Cmax), the minimum plasma 
concentration (Cmin), and area under the concentration-time curve from 0 to 12 hours 
(AUC0-12hr) to be 62 g/mL, 59 g/mL, and 734 g/mLhour, respectively.  The 
pharmacokinetics of vemurafenib have been shown to be dose proportional between 
240 and 960 mg BID, and a population PK analysis also confirmed that the 
pharmacokinetics of vemurafenib are linear. The median of the individual elimination 
half-life estimate for vemurafenib is 57 hours (the 5th and 95th percentile range is 
30120 hours). 
Vemurafenib at 960 mg BID as a 240-mg tablet is absorbed with a median time to 
maximum concentration (tmax) of approximately 4 hours.  Vemurafenib exhibits marked 
accumulation after repeat dosing at 960 mg BID, with high inter-patient variability.  On 
the basis of the population PK analysis, the median accumulation ratio estimate for the 
BID regimen is 7.36.  In the Phase II study, mean plasma vemurafenib concentrations 
4 hours postdose increased from 3.6 g/mL on Day 1 to 49.0 g/mL on Day 15 
(range: 5.4118 g/mL). 
At steady state, the mean vemurafenib exposure in plasma is stable (concentrations 
predose and 24 hours after the morning dose), as indicated by the mean ratio of 1.13.  
Relatively high marked inter-patient variability in plasma exposure (area under the 
plasma concentration-time curve [AUC]; range: 3246%) was observed at the 
steady-state dose reduction. 
Following oral dosing, the absorption rate constant for the population of metastatic 
melanoma patients was estimated to be 0.19 hr1 (with 101% intra-patient variability). 
The apparent volume of distribution for vemurafenib in patients with metastatic 
melanoma on the basis of population PK analysis is estimated to be 91 L (with 64.8% 
intra-patient variability).  Vemurafenib is highly bound to human plasma proteins in vitro 
(99%). 
The relative proportions of vemurafenib and its metabolites were characterized in a 
human mass-balance study.  On average, 95% of the dose was recovered within 
18 days, the majority (94%) in feces, with 1% recovered in urine.  The parent 
compound was the predominant component (95%) in plasma (refer to the 
Vemurafenib IB).  CYP3A4 is identified as the primary enzyme responsible for 
vemurafenib metabolism.
The commercial dosage form of vemurafenib is a 240-mg film-coated tablet.

Efficacy of Vemurafenib in Patients with BRAFV600E
MutationPositive Metastatic Melanoma
Study NO25026 was a Phase III, open-label, multicenter, international study of 
vemurafenib in previously untreated patients with BRAFV600E mutation–positive 
unresectable or metastatic melanoma.  Patients were randomized to treatment with 
vemurafenib (960 mg BID) or dacarbazine (DTIC) (1000 mg/m2 every 3 weeks).
A total of 675 patients were randomized to receive vemurafenib (n337) or DTIC 
(n338; Vemurafenib IB).  Randomization was stratified according to disease stage, 
serum LDH level, Eastern Cooperative Oncology Group (ECOG) Performance Status, 
and geographic region.  Baseline characteristics were well balanced between treatment 
groups.  Of the patients randomized to receive vemurafenib, most patients were male 
(59%) and Caucasian (99%), the median age was 56 years (28% were 65 years old), 
all patients had ECOG Performance Status of 0 or 1, and the majority of patients (66%) 
had Stage M1c disease.
The co-primary efficacy endpoints of the study were overall survival (OS) and 
progression-free survival (PFS).  Key secondary endpoints included confirmed best 
overall response rate (BORR) and response duration.
Statistically significant and clinically meaningful improvements were observed in OS 
(p0.0001) and PFS (p0.0001, by unstratified log-rank test).  OS was longer with 
vemurafenib treatment compared with DTIC, with a hazard ratio of 0.37 (95% CI: 0.26, 
0.55), which represents a 63% decrease in the hazard of death with vemurafenib 
compared with DTIC (Vemurafenib IB).  KaplanMeier estimates of the 6-month survival 
rates were 84% (95% CI: 78%, 89%) for vemurafenib and 64% (95% CI: 56%, 73%) for 
DTIC.  Consistent improvement in OS, PFS, and confirmed BORR in favor of 
vemurafenib treatment was generally observed across subgroups defined by age, sex, 
baseline serum LDH level, ECOG Performance Status, metastatic disease stage, and 
geographic region.  Ninety-four patients (28%) treated with vemurafenib in the 
aforementioned Phase III study were 65 years old.  The effects of vemurafenib on OS, 
PFS, and confirmed BORR were similar for patients 65 and 65 years old.
1.2.1.5
Safety of Vemurafenib
The safety evaluation of vemurafenib is based on results in patients from 
three Genentech clinical pharmacology studies (Study NP22676, n25; Study NP25163, 
n52; and Study NP25158, n7), a Phase I study (Study PLX06-02, n108; 
Vemurafenib IB), a single-arm, Phase II study in previously treated patients with 
BRAFV600 mutationpositive Stage IV melanoma (Study NP22657, n132; Vemurafenib 
IB), and a Phase III, randomized, open-label, multicenter, global study in patients with 
unresectable Stage IIIC or Stage IV BRAFV600 mutationpositive melanoma 
(Study NO25026, n675; Vemurafenib IB).  The type and incidence of adverse events 
observed across all studies in patients with BRAFV600 mutationpositive unresectable or 
metastatic melanoma were consistent.

In the clinical pharmacology Study NP25163, all 52 patients (100%) had at least one 
adverse event.  Nearly all patients (96%) had at least one treatment-related adverse 
event.  The majority of adverse events were of mild or moderate intensity.  The most 
common adverse events (reported in 30% of patients) in the vemurafenib group were 
fatigue (58%), arthralgia (58%), nausea (50%), rash (38%), and diarrhea (33%).  
Fifty-four percent of patients had at least one Grade 3 adverse event; 40% of patients 
had at least one treatment-related adverse event.  The most commonly reported 
treatment-related adverse events (incidence 5%) were squamous cell carcinoma (SSC)
of skin (23%), increased gamma glutamyl transferase (GGT; 9%), basal cell carcinoma 
(BCC; 7%), rash (7%), maculopapular rash (6%), and arthralgia (6%).  Twelve patients 
(23%) experienced at least one Grade 4 adverse event, including 2 patients who 
experienced two Grade 4 adverse events.  Five of the 12 patients had Grade 4 adverse 
events that were assessed by the investigator as treatment related.  The most frequent 
Grade 4 adverse event was increased GGT (n5 patients, assessed as related to 
treatment in 4 patients).  The other Grade 4 adverse events were hyperuricemia 
(assessed as related to treatment) and pneumonia, sepsis, convulsion, pseudomonas 
infection, staphylococcal infection, multi-organ failure, and pulmonary embolism (all of
which were assessed as unrelated to study treatment).
Study PLX06-02 (Vemurafenib IB) assessed the safety of escalating doses of 
vemurafenib.  At the highest dose administered (1120 mg BID), dose-limiting rash 
(National Cancer Institute Common Terminology Criteria for Adverse Events 
[NCI CTCAE] Grade 3) and fatigue (Grade 3) were observed in multiple patients.  
Vemurafenib doses of up to 960 mg BID (the MTD) were generally well tolerated.
In the Phase II clinical trial (Study NP22657; Vemurafenib IB), all patients experienced at 
least one adverse event, the most common of which were arthralgia (68%), fatigue 
(57%), rash (54%), photosensitivity (52%), nausea (42%), alopecia (38%), pruritus 
(32%), diarrhea (32%), skin papilloma (31%), and hyperkeratosis (30%).  Seventy-three 
percent of patients experienced at least one Grade 3 adverse event.  Sixty-one percent 
of patients had at least one Grade 3 treatment-related adverse event.  The most 
commonly reported, treatment-related adverse events (incidence 5%) were squamous 
cell carcinoma (SCC) of skin (23%), increased serum GGT (9%), BCC (7%), rash (7%), 
maculopapular rash (6%), and arthralgia (6%).  The Vemurafenib IB summarizes the 
Grade 3 or 4 study drugrelated adverse events observed in Study NP22657.
In the Phase III randomized study of vemurafenib versus DTIC (BRIM-3, 
Study NO25026, clinical cutoff:  1 March 2011; Vemurafenib IB), the safety results 
showed that vemurafenib was generally tolerable and toxicity was manageable with 
dose modifications.  Ninety-nine percent and ninety-one percent of patients in the 
vemurafenib and DTIC treatment groups, respectively, experienced at least one adverse 
event.  The majority of adverse events were of mild or moderate intensity.  The most 
common adverse events (reported in 30% of patients) in the vemurafenib group were 
in the system organ class of skin and subcutaneous tissue disorders; the most common 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
22
of which were alopecia, rash, and photosensitivity.  Other adverse events that occurred 
in 10% of vemurafenib-treated patients and at an incidence of more than twice that 
observed in the DTIC group included SCC of skin, skin papilloma, arthralgia, headache, 
dysgeusia, pyrexia, peripheral edema, pain in extremity, myalgia, decreased appetite, 
diarrhea, hyperkeratosis, seborrheic keratosis, and dry skin. Of the 37 patients who 
switched from DTIC to vemurafenib, 32 patients (86%) had at least one adverse event 
and 26 patients (70%) reported at least one treatment-related adverse event.  The 
majority of adverse events were of mild or moderate intensity.
Fifty-nine percent of patients in the vemurafenib arm and thirty-three percent of patients 
in the DTIC arm experienced one or more adverse events of Grade 3 in intensity.  
Treatment-related adverse events of Grade 3 occurred in 49% of patients in the 
vemurafenib arm and 20% in the DTIC arm.  Sixteen percent and nine percent of 
vemurafenib-treated patients had cutaneous squamous cell carcinoma (cuSCC) and 
keratoacanthoma (KA), respectively, compared with 1% and 0% for DTIC-treated 
patients.  For reporting purposes, all cases of cuSCC and KA were considered to be 
treatment related, Grade 3, and serious.  Other common Grade 3 adverse events in the 
vemurafenib group included photosensitivity reaction (9%), rash (8%), maculopapular 
rash (8%), and arthralgia (4%); the corresponding frequency of these adverse events in
the DTIC group were 0%, 0%, 0%, and 1%.  The most common Grade 3 adverse 
event in the DTIC group was neutropenia, occurring in 9% of patients; 1% of patients 
in the vemurafenib group experienced neutropenia.  Of the 37 patients who crossed over 
from DTIC to vemurafenib, 11 (30%) experienced one or more Grade 3 adverse 
event after crossover.  These events consisted of fatigue (2 patients), muscle weakness, 
pyrexia, anemia, hyperkeratosis, BCC, maculopapular rash, rash, cellulitis, 
palmar-plantar erythrodysesthesia syndrome, and decreased neutrophil counts 
(all 1 patient each).  Of these, eight events were considered by the investigator to be 
treatment related.
The percentage of patients who experienced one or more Grade 4 adverse event was 
lower in the vemurafenib group (13 patients [4%]) than in the DTIC group (22 patients 
[8%]).  Grade 4 adverse events in the vemurafenib group included pulmonary embolism
(3 patients), increased GGT (2 patients), increased blood creatine phosphokinase (CPK), 
increased blood bilirubin, increased lipase, ageusia, intraventricular hemorrhage, 
pneumonia, pneumothorax, respiratory distress, and neutropenia (1 patient each).  
Five patients treated with vemurafenib had a total of six Grade 4 adverse events that 
were assessed as related to treatment (increased blood bilirubin, GGT increased 
[2 patients], ageusia, increased CPK, and neutropenia).  One of the 37 patients who 
crossed over experienced a Grade 4 decreased neutrophil count after crossover.  It was 
assessed as unrelated to treatment and non-serious.
Grade 5 adverse events were reported in 6 patients (2%) in the vemurafenib group.  
Only one adverse event (intracranial tumor hemorrhage) was assessed as treatment
related.  Each of the other 5 patients experienced the following Grade 5 adverse events 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
23
(all unrelated to study treatment):  general physical health deterioration, cerebrovascular 
accident, pneumonia, aortic aneurysm rupture, and cardiac failure.  Grade 5 adverse 
events were reported in 8 DTIC-treated patients (3%).  Fatigue and mucosal 
inflammation, initially classified as Grade 5 adverse events in 1 patient, were 
subsequently considered to be symptoms of disease progression and downgraded to 
Grade 1, resulting in a total of 7 patients with Grade 5 adverse events.  Only one 
adverse event (shock) was assessed as treatment related.  Dyspnea, lung infection, 
cardiac arrest, and cardiac tamponade were reported in 1 patient each, and 
cardiopulmonary failure was reported in 2 patients.  No Grade 5 adverse events were 
reported in the 37 patients who crossed over from DTIC to vemurafenib.
The incidence of cuSCC in vemurafenib-treated patients was approximately 20% across 
studies.  The majority of the excised lesions reviewed by an independent central 
dermatopathology laboratory were classified as SCCKA subtype or with mixed KA 
features (52%), both of which are less invasive types of cuSCC.  Most lesions classified 
as “other” (43%) were benign skin lesions (e.g., verruca vulgaris, actinic keratosis, 
benign keratosis, cyst/benign cyst).  cuSCC usually occurred early in the course of 
treatment, with a median time to the first appearance of 78 weeks.  Of the patients who 
experienced cuSCC, approximately 33% experienced more than one occurrence, with a 
median time between occurrences of 6 weeks.  Cases of cuSCC were typically managed 
with simple excision, and patients generally continued receiving treatment without dose 
modification.  A risk mitigation plan, including regular dermatologic and head and neck 
examinations and chest computed tomography (CT) scans, has been established to 
monitor for and treat SCC (both cutaneous and non-cutaneous) in patients receiving 
vemurafenib in clinical trials (see Section 5.1.2.3).
Eight skin lesions in 7 of 337 vemurafenib-treated patients were reported as new primary 
malignant melanomas in Study NO25026 (Vemurafenib IB).  No cases were reported in 
338 patients treated with DTIC.  Cases were managed with excision and without 
sequelae, and patients continued treatment without dose adjustment.  Surveillance 
measures to monitor for the occurrence of new primary melanomas as well as cuSCC 
are outlined in Section 5.1.2.3.
Severe dermatologic reactions have been reported in patients receiving vemurafenib, 
including rare cases of Stevens-Johnson syndrome and toxic epidermal necrolysis. One 
notable treatmentrelated serious adverse event occurred in a vemurafenib-treated 
patient in the pivotal Phase III trial (Study NO25026) after the 1 March 2011 clinical 
cutoff date for safety.  This patient developed toxic epidermal necrolysis.  The event 
improved slightly after the patient was given treatment but was not resolved at last report.  
The patient was discharged from the hospital and permanently discontinued treatment 
with vemurafenib.
As of 31 March 2013, 12 cases of drug reaction with eosinophilia and systemic 
symptoms (DRESS) syndrome have been observed with vemurafenib treatment.  


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
24
No fatal cases have been reported.  The time to onset was 7 to 25 days.  In the majority 
of patients (n7), vemurafenib was discontinued.  Some patients (n5) were treated 
with systemic steroids with corresponding improvement or resolution of symptoms.  
In addition, 2 patients who were treated with vemurafenib after ipilimumab presented 
with Grade 3 rash and had biopsies that showed pathology consistent with drug 
hypersensitivity reaction (Harding et al. 2012).  Full details are provided in the current 
Vemurafenib IB. 
Two cases of SCC of the head and neck have been reported in 2 patients treated with 
vemurafenib in excess of 300 days while enrolled in a clinical trial.  Pathology 
examination of both tumors (one a primary tonsillar tumor, the other a primary tongue 
tumor) revealed the presence of invasive SCC.  Of note, the first patient’s medical 
history was significant for risk factors for head and neck cancer and the tumor tissue 
tested positive for human papilloma virus (HPV).  The second patient does not appear to 
possess any risk factors for head and neck cancer, and the preliminary examination of 
the tumor tissue did not reveal the presence of HPV genome.  Full details are provided 
in the current Vemurafenib IB.
Five cases of adenomatous colonic polyps have been reported in patients who received 
vemurafenib for more than 2 years (Chapman et al. 2012).  The first patient developed 
an upper gastrointestinal bleed, and, on work-up, was found to have duodenal ulceration 
(non-malignant), hyperplastic gastric polyps, and five colonic polyps (three of which were 
adenomatous).  A previous colonoscopy in 2008, at the time of a jejunal resection for 
recurrent melanoma, documented no prior evidence of colonic polyps.  All polyps were 
resected, and the patient subsequently resumed vemurafenib therapy.  The second 
patient was found, on elective colonoscopy, to have seven colonic polyps (five of which 
were adenomatous), and all were detected and removed.  This patient had not 
undergone a previous colonoscopy.  The third patient had, on elective colonoscopy, 
10 colonic polyps (7 of which were adenomatous).  This patient had a previous 
colonoscopy 7 years prior to starting vemurafenib.  The fourth patient had, on elective 
colonoscopy, one adenomatous colonic polyp.  The fifth patient had, on elective 
colonoscopy, three adenomatous colonic polyps.  The latter two patients had histories of 
no prior colonoscopy.  In addition, a patient in the Expanded Access Program had one 
colonic adenoma discovered after treatment with vemurafenib for 0.57 years.  This 
patient had a colonoscopy 1.3 years prior to starting vemurafenib, and a polyp was 
found and resected at that time.
One case of progression of NRAS-mutated chronic myelomonocytic leukemia occurred 
in a male patient with metastatic melanoma treated with vemurafenib for less than 
2 weeks (Callahan et al. 2012).  After the first dose of vemurafenib, laboratory results 
showed a marked leukocytosis and monocytosis, and vemurafenib treatment was 
subsequently held. There was a temporal relationship between vemurafenib treatment 
and increase in WBC and absolute monocyte counts through multiple cycles of 
dechallenge and rechallenge.  In vitro studies demonstrated proliferation of the leukemic

cell population upon stimulation with a BRAF inhibitor, an effect that was reversed upon 
addition of MEK inhibitor.  Further, the cells exhibited dose-dependent and reversible 
activation of extracellular-signal-regulated kinase (ERK) in the NRAS-mutated leukemic 
clone.  A second case of progression of a preexisting RAS-mutated malignancy 
(pancreatic adenocarcinoma with KRAS mutation) was reported with vemurafenib in 
2014. On the basis of its mechanism of action, vemurafenib may cause progression of 
cancers associated with RAS mutations.  Vemurafenib should be used with caution in 
patients with a prior or concurrent cancer associated with RAS mutation.  Full details are 
provided in the current Vemurafenib IB.
In a Phase I trial (Study CA 184161, sponsored by Bristol-Myers Squibb), asymptomatic 
Grade 3 increases in transaminases and bilirubin occurred with concurrent 
administration of ipilimumab (3 mg/kg) and vemurafenib (960 mg BID or 720 mg BID) 
(Ribas et al. 2012).  All liver laboratory abnormalities were asymptomatic and reversible 
with permanent discontinuation of the study drugs or, in some cases, administration of 
corticosteroids.  On the basis of these data, concurrent administration of ipilimumab and 
vemurafenib is not recommended outside of a clinical trial.  Full details are provided in 
the current Vemurafenib IB. 
An analysis of liver-related adverse events reported with vemurafenib use showed that 
63 cases (out of an estimated exposure of approximately 20,000 patients) of medically
confirmed serious adverse events were consistent with drug-induced liver injury on the 
basis of clinical chemistry criteria from the Drug-Induced Liver Injury Expert Working 
Group (Aithal et al. 2011).  Of the 63 cases, two were assessed as severe; both were 
reported as hepatic failure, and the outcomes of both cases are considered resolved. 
There were no reported deaths among the 63 cases of liver injury. The median time to 
onset of the adverse events was 44 days after initial dose.  The median ALT to alkaline 
phosphatase (ALP) ratio was calculated as 1.5, suggesting a trend toward cholestatic 
pattern of liver injury. The analysis did not reveal any risk factors or populations at risk.
A review of the Roche safety database found neutropenia to be an uncommon (6 cases 
per 1000 person-years, 0.6%) adverse drug reaction associated with the use of 
vemurafenib, typically occurring during the first 612 weeks of treatment. Neutropenia
appeared to be reversible, usually within 2 weeks, with temporary interruption, dose 
reduction, or discontinuation of vemurafenib and, in some cases, was managed with 
granulocyte colonystimulating factor (GCSF).
The effects of vemurafenib on the QT interval were investigated as part of the Phase II 
Study NP22657 (Vemurafenib IB).  This was not a “thorough” QT study as defined by 
health authorities because vemurafenib cannot be administered to healthy volunteers 
and it was not feasible to administer a positive or negative control to patients with 
metastatic melanoma.  However, the centrally read ECG data obtained in triplicate at 
serial, time-matched points before and after dosing met the regulatory expectations for 
robust assessment of oncology therapeutics on the QT interval.  The maximum 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
26
absolute corrected QT (QTc) values at any point after dosing were as follows:  450 
millisecond (ms), 49 patients (37.1%); 480 ms, 6 patients (4.5%); 500 ms (Grade 3), 
2 patients (1.5%).  One patient (0.8%) had a maximal QTc increment 60 ms (Grade 2) 
compared with baseline.  The upper boundary of the one-sided 95% CI for mean QTc 
prolongation reached a maximum of 17.7 ms on Day 105 of study treatment, based on
measurements in 90 patients.  Mean QTc interval prolongation closely tracked with the 
mean vemurafenib steady-state concentration over time.  None of the QT prolongation 
events were serious or led to premature withdrawal from treatment or dose 
modification/interruption; none were clearly associated with prolongation of cardiac 
repolarization, arrhythmia, or any other cardiac function disorder.  Additional information 
on the relationship between vemurafenib exposure and QT interval prolongation may be 
found in the Vemurafenib IB.
As of Q2 2014, an adverse drug reaction of pancreatitis has been identified in patients 
treated with vemurafenib.  Seventeen cases of pancreatitis with no strong risk factors 
or alternative explanations were reported.  Eight of the seventeen cases were assessed 
as likely associated with vemurafenib use on the basis of event onset latency and 
rechallenge/dechallenge information.  The clinical presentation including mild to 
moderate severity was consistent with the clinical picture of drug-induced pancreatitis 
(Lankisch et al. 1995).  
As of Q4 2014, an adverse drug reaction of potentiation of radiation treatment toxicity 
has been identified in patients treated with radiation either prior, during, or subsequent to 
vemurafenib treatment.  This is based on twenty cases of radiation injuries, adjudicated
as radiation recall (n 8) and radiation sensitization (n 12).  The nature and severity of 
the events in all 20 cases were evaluated as worse than expected for the normal tissue 
tolerance to therapeutic radiation with fatal outcome in 3 cases.  The reaction was seen 
in the skin, esophagus, lung, liver, rectum, and urinary bladder.  Vemurafenib should be 
used with caution when given concomitantly or sequentially with radiation treatment.  
Full details are provided in the current Vemurafenib IB. 
Acute kidney injury, including interstitial nephritis, has been observed in patients 
treated with vemurafenib.  The majority of these cases have been characterized by mild 
to moderate increases in serum creatinine (some observed in the setting of dehydration
events), with recovery after dose modification. Serum creatinine will be monitored 
throughout the study. Vemurafenib acute kidney injury dose modification guidelines 
should be used when applicable, and it is recommended to routinely monitor serum 
creatinine levels in all patients undergoing vemurafenib therapy.
Dupuytren’s contracture and plantar fascial fibromatosis have been reported with 
vemurafenib.  The majority of cases were Grade 1 or 2, but severe, disabling cases of 
Dupuytren’s contracture have also been reported.

STUDY RATIONALE AND BENEFIT-RISK ASSESSMENT
This is an open-label, multicenter, non-randomized study to provide continued access to 
vemurafenib for eligible patients with BRAFV600 mutationpositive malignancy (including 
metastatic melanoma and other cancer types) who were previously enrolled and treated 
in an antecedent vemurafenib study protocol without meeting the protocol’s criteria for 
disease progression or are being treated beyond progression and still deriving clinical 
benefit, as assessed by investigator.  
Safety evaluations will be conducted during the study.  Safety evaluations will begin on 
Day 1 of the study, and safety will continue to be monitored throughout the study until 
28 days after the last dose of study drug.  Adverse events related to the study drug will 
be monitored until resolution.
In summary, these patients have limited alternative treatment options and may 
potentially benefit from continued treatment with vemurafenib.  Therefore, the potential 
benefits of participating in this study outweigh the potential associated risks.
2.
OBJECTIVES
2.1
PRIMARY OBJECTIVE
The primary objective of this study is to provide continued access to vemurafenib for 
eligible patients with BRAFV600 mutationpositive malignancy who were previously 
treated in an antecedent vemurafenib protocol and did not meet the protocol’s criteria for 
disease progression or are being treated beyond progression and still deriving clinical 
benefit, as assessed by investigator, and may potentially benefit from continued
treatment with vemurafenib. 
2.2
SECONDARY OBJECTIVE
The secondary objective is to collect and describe safety and tolerability data for patients 
who continue vemurafenib treatment in this extension (rollover) study.
3.
STUDY DESIGN
3.1
DESCRIPTION OF STUDY
3.1.1
Overview
This is an open-label, multicenter, non-randomized study to provide continued access to 
vemurafenib for eligible patients with BRAFV600 mutationpositive malignancy who were 
previously enrolled and treated in an antecedent vemurafenib protocol and did not meet 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
28
the protocol’s criteria for disease progression or are being treated beyond progression 
and still deriving clinical benefit (as assessed by the investigator) and may therefore 
potentially benefit from continued treatment with vemurafenib. The maximum number of 
days between the last dose of study drug in the antecedent protocol and first dose in 
this extension (rollover) study will be 15 days.  Results of the study completion visit or 
other visit in the antecedent protocol may be used as screening/baseline for this 
extension (rollover) study.  Screening/baseline is combined into one visit if completed 
within time intervals, as specified in Section 4.5.2.1 and Appendix 1. The first 
vemurafenib treatment in the extension (rollover) study will be recorded as Cycle 1, 
Day 1.  Patients will receive treatment with oral vemurafenib at 960 mg BID, 720 mg BID, 
or 480 mg BID, depending on the last dose in the antecedent protocol.  Treatment will 
continue until progression of disease or as long as the patient is deriving clinical benefit, 
as judged by the investigator (case-by-case decision with approval of the Medical
Monitor), death, withdrawal of consent, unacceptable toxicity, loss to follow-up, or 
decision of the Sponsor to terminate the study, whichever occurs first.
One cycle is defined as 28 days.  Clinic visits will occur on Day 1 of Cycles 17 and on 
Day 1 of every other cycle through Cycle 15. Then, for patients still receiving treatment, 
clinic visits will occur on Day 1 of every third cycle (i.e., screening/baseline and Day 1 of 
every third cycle from Cycle 18[see Appendix 1] for patients with 17 cycles of 
vemurafenib on an antecedent study) until unacceptable toxicity or disease progression, 
as defined by the investigator.  In patients with measurable disease, tumor assessments 
will be conducted for purposes of evaluating whether treatment should be discontinued 
via routine tumor assessments (CT/magnetic resonance imaging [MRI]) consistent with 
institutional standards of care, as outlined in the Schedule of Assessments (see 
Appendix 1).  
Tumor assessments as specified and conducted in the antecedent protocol, including 
any evaluable and measurable disease, will have been documented at screening in the 
antecedent protocol.  In the extension (rollover) study, tumor assessments, including 
radiological tumor assessments of chest, abdomen, and pelvis (C/A/P) for measuring 
extent or progression of disease (CT scan is the preferred method) will be done at the 
discretion of the investigator according to local institutional standard of care for purposes 
of evaluating whether treatment should be discontinued.
Safety evaluations will also be conducted during the study. Safety evaluations will begin 
on Day 1 of the study and will continue throughout the study until 28 days after the last 
dose of study drug, withdrawal of consent, initiation of non-protocol therapy, death, or 
loss to follow-up, whichever is earliest.  Adverse events related to the study medication 
will be monitored until resolution.  The tolerability and toxicity (safety) profile of 
vemurafenib will be evaluated using the NCI CTCAE, Version 4.0. 
The target population includes patients with BRAFV600 mutationpositive malignancy 
(including metastatic melanoma or other cancer types) who were previously enrolled and 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
29
treated in an antecedent vemurafenib protocol and did not meet the protocol’s criteria for
disease progression or are being treated beyond progression and still deriving clinical 
benefit, as assessed by investigator and may potentially benefit from receiving continued 
treatment with vemurafenib. Patients with malignant tumor types other than malignant 
melanoma harboring a V600-activating mutation of BRAF who have no acceptable 
standard treatment options will also be allowed to participate in the trial. 
3.2
LENGTH OF STUDY
Treatment will continue until disease progression (as defined by investigator) or as long 
as the patient is deriving clinical benefit, as assessed by investigator, if treated beyond 
progression (case-by-case decision discussed and approved by the Medical Monitor), 
death, withdrawal of consent, unacceptable toxicity, loss to follow-up, or decision of the 
Sponsor to terminate the study, whichever occurs first. 
3.3
END OF STUDY
The study will end when all enrolled patients have discontinued study treatment and 
have been followed for safety assessment until 28 days after the last dose of study drug, 
death, withdrawal of consent, loss to follow-up, or if the Sponsor has decided to 
terminate the study, whichever occurs first.
3.4
RATIONALE FOR STUDY DESIGN
This is an open-label, multicenter, non-randomized study to provide continued access to 
vemurafenib for eligible patients with BRAFV600 mutationpositive malignancies who 
participated in an antecedent vemurafenib protocol and did not meet the protocol’s 
criteria for disease progression or are being treated beyond progression and still deriving 
clinical benefit, as assessed by investigator, and may potentially benefit from continued 
treatment with vemurafenib.  The purpose of the current protocol is to provide such 
patients with continued access to treatment with vemurafenib.
3.4.1
Rationale for Test Product Dosage
The dose of vemurafenib in this study will be 960 mg BID, which is the approved dose of 
vemurafenib for malignant melanoma or, if the dose was reduced in an antecedent 
protocol, the dose of the last visit of the antecedent study (minimum 480 mg orally BID) 
will be used.
3.4.2
Rationale for Patient Population and Analysis Groups
Vemurafenib is approved in the United States for the treatment of patients with 
unresectable or metastatic melanoma with BRAFV600E mutation and in the European 
Union as monotherapy for the treatment of adult patients with BRAFV600
mutation-positive unresectable or metastatic melanoma. Vemurafenib is also approved 
or has been submitted for approval in other countries worldwide.  Accordingly, patients 
enrolled in this study may have unresectable Stage IIIc or Stage IV metastatic 
melanoma positive for the BRAFV600 mutation.  In addition, patients with other malignant 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
30
tumor types harboring a V600-activating mutation of BRAF who have no acceptable 
standard treatment options will also be allowed to participate in the trial.
3.5
OUTCOME MEASURES 
3.5.1
Efficacy Outcome Measures
There are no protocol-specific efficacy outcome measures for this study.
3.5.2
Safety Outcome Measures
The safety outcome measures for this study are as follows:

Incidence, nature, and intensity (severity) of adverse events and serious adverse 
events, graded according to the NCI CTCAE v4.0
4.
MATERIALS AND METHODS
4.1
PATIENTS
The target population will be patients with BRAFV600 mutationpositive melanoma or 
other malignancies who were previously enrolled in an antecedent vemurafenib protocol 
and may potentially still benefit from treatment with vemurafenib.

2.
Female patients of childbearing potential and male patients with partners of 
childbearing potential must agree to always use two adequate methods of 
contraception including at least one method with a failure rate of 1% per year 
during the course of this study and for at least 6 months after completion of study 
treatment. 

Females of childbearing potential are defined as sexually mature women 
without prior hysterectomy who have had any evidence of menses in the past 
12 months.  In order to be considered not of childbearing potential, amenorrhea 
for a period of 12 months or longer must have occurred in the absence of 
chemotherapy, anti-estrogen therapy, or ovarian suppression.

3.
Negative serum pregnancy test within 7 days prior to commencement of dosing in 
women of childbearing potential; women of non-childbearing potential may be 
included if they are either surgically sterile or have been naturally menopausal for 
1 year.  Women of non-childbearing potential need not undergo the pregnancy test.
4.1.2
Exclusion Criteria
Patients who meet any of the following criteria will be excluded from study entry:
1.
Adverse event requiring discontinuation of vemurafenib in the antecedent protocol
2.
Progressive disease during the antecedent protocol.  If approval to treat beyond 
progression was already given in the antecedent protocol, the patient may roll over 
into the current protocol without Sponsor’s approval.  Under special circumstances, 
when it is felt that the patient may clinically benefit from continued therapy with 
vemurafenib, enrollment into this protocol and dosing beyond progression may be
considered if it is judged by the investigator, in consultation with the Sponsor, to be 
in the best interest of the patient.  All such cases will require approval of the 
Sponsor before enrolling the patient into this protocol. 
3.
Meeting any of the following exclusion criterion of the antecedent study at the time 
the patient is considered for the extension (rollover) study:

Current, recent (within 28 days prior to Day 1), or planned use of any anti-tumor 
therapy outside of this study

Any other serious concomitant medical conditions that, in the opinion of the 
investigator, would compromise the safety of the patient or compromise the 
patient’s ability to participate in the study

History of malabsorption or other clinically significant metabolic dysfunctions

History of clinically significant cardiac or pulmonary dysfunction as specified in 
antecedent study
4.2
METHOD OF TREATMENT ASSIGNMENT AND BLINDING
All patients will receive vemurafenib under this protocol.

4.3.3
Investigational Medicinal Product Accountability
The investigational medicinal product (IMP) required for completion of this study
(supplied as 240-mg film-coated tablets packed in bottles for oral administration) will be 
provided by Roche.  The investigational site will acknowledge receipt of the IMP, through 
use of the interactive web (or voice) response system (IxRS) to confirm the shipment 
condition and content.  Any damaged shipments will be replaced. 
The IMP will either be disposed of at the study site according to the study site’s 
institutional standard operating procedure or returned to Roche with the appropriate 
documentation.  The site's method of IMP destruction must be agreed upon by Roche.  
The site must obtain written authorization from Roche before any IMP is destroyed, and 
IMP destruction must be documented on the appropriate form.
Accurate records of the IMP received at, dispensed from, returned to, and disposed of 
by the study site should be recorded on the Drug Inventory Log.
4.3.4
Post-Trial Access to Vemurafenib 
Roche does not intend to provide vemurafenib to patients after the conclusion of the 
study or any earlier withdrawal (see Section 3.3). 
4.4
CONCOMITANT THERAPY
4.4.1
Permitted Therapy
Concomitant therapy includes any prescription medications or over-the-counter 
preparations used by a patient within 15 days before enrolling into this study through to 
the end of treatment visit.  Patients who use oral contraceptives, hormone-replacement 
therapy, or maintenance therapy should continue their use as outlined in the eligibility 
criteria concerning adequate contraception during and for at least 6 months after the 
completion of study treatment (see Section 4.1.1).  Patients who experience toxicities 
may be treated symptomatically as clinically indicated.  All concomitant medications 
should be recorded on the appropriate electronic Case Report Form (eCRF).
At the discretion of the investigator, prophylactic anti-emetic and antidiarrheal 
medications may be used per standard clinical practice before doses of the study drug.  
Hematopoietic growth factors (e.g., erythropoietin and GCSF) and pain medications 
administered as dictated by standard practice are acceptable while the patient is 
enrolled in the study.  However, growth factors should not be administered 
prophylactically before initial treatment with the study drug.
Because of the underlying illness and the frequency of co-existent medical conditions in 
this patient population, all concomitant medication or treatment required by the patient 
will be administered at the discretion of the treating physician.

4.4.2
Prohibited Therapy
Use of the following therapies is prohibited during the study (i.e., from 7 days before the 
initiation of vemurafenib treatment [on Study GO28399] until the end of treatment visit):

St. John’s wort or hyperforin

Any concomitant therapy intended for the treatment of cancer (approved by health 
authorities or experimental), including chemotherapy, radiation therapy, 
immunotherapy, hormonal therapy, biologic therapy, investigational agents, or 
herbal therapy; certain forms of radiation therapy may be considered for pain 
palliation following consultation with the medical monitor.  Study treatment should be 
suspended during radiation therapy.  Undergoing radiation therapy 1 week prior to 
first administration of vemurafenib and stereotactic radiotherapy is prohibited. 
Patients who require the use of any of these agents will be discontinued from study 
treatment and followed for safety outcomes for 28 days after the last dose of study 
treatment or until the initiation of another anti-cancer therapy, whichever comes first.  
Follow-up for new primary malignancies will continue per investigator’s discretion.
4.4.3
Medication Precautions in Case of Drug-Drug Interactions
4.4.3.1
Vemurafenib
Results from a drug-drug interaction study in patients with metastatic melanoma 
demonstrated no interaction of vemurafenib with CYP2C19 and CYP2C9.  However, 
drug interactions were observed with CYP1A2 and CYP3A4.
CYP1A2 inhibition was observed when a single dose of caffeine (a CYP1A2 substrate) 
was co-administered after repeat dosing with vemurafenib for 15 days, resulting in a 
2.6fold increase in the mean AUC of caffeine.
CYP3A4 induction was observed when a single dose of midazolam (a CYP3A4 
substrate) was co-administered after repeat dosing with vemurafenib for 15 days, 
resulting in a 39% decrease in the mean AUC of midazolam.
An interaction between vemurafenib and dextromethorphan (a CYP2D6 substrate) was 
suggested by a mean increase in dextromethorphan AUC0-last of 47% based on the no 
effect 90% CI boundary.  However, this interaction is not likely to be the result of the 
inhibition of CYP2D6 by vemurafenib, because the AUC0-last of the dextromethorphan 
metabolite dextrorphan also increased by 46%.
In nonclinical in vitro evaluation, the concentration for 50% inhibition of vemurafenib to 
CYP2C9 was 5.9 M.  When a single dose of warfarin (a CYP2C9 substrate) was
co-administered after repeat dosing with vemurafenib for 15 days, some patients 
exhibited increased warfarin exposure (mean 18% for S-warfarin).
In summary, vemurafenib may increase the plasma exposure of drugs predominantly 
metabolized by CYP1A2 and decrease the plasma exposure of drugs predominantly 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
35
metabolized by CYP3A4.  If CYP1A2 substrates must be co-administered with 
vemurafenib, investigators should assess the safety risk associated with a potential 
increase in plasma concentrations of CYP1A2-metabolized drugs.  If CYP3A4 substrates 
must be co-administered with vemurafenib, investigators should monitor for signs of 
reduced benefit of CYP3A4-metabolized drugs because of a potential decrease in their 
plasma concentration.  Dose adjustments for medications predominantly metabolized via 
CYP1A2 or CYP3A4 should be considered on the basis of their therapeutic windows 
before concomitantly treating with vemurafenib.  Doses of concomitant CYP1A2 and 
CYP3A4 metabolized drugs, but not the dose of vemurafenib, may be adjusted as 
necessary to alleviate the impact of drug interaction.
Caution should be exercised when vemurafenib is co-administered with warfarin 
(CYP2C9) in patients with melanoma (see prohibited concomitant therapies in 
Section 4.4.2).  
No dose adjustment is recommended for drugs metabolized by CYP2D6 or CYP2C19.
Less than 10% of metabolites of vemurafenib were detected in plasma in nonclinical 
studies and in clinical data from a mass-balance study with 14C-vemurafenib in patients 
with melanoma (Study NP25158).  Nonclinical studies suggest that CYP3A4 metabolism 
and subsequent glucuronidation are responsible for the metabolism of vemurafenib.  
No clinical data are currently available evaluating the effects of CYP3A4 inducers or 
inhibitors on vemurafenib exposure.
In vitro studies have demonstrated that vemurafenib is both a substrate and an inhibitor 
of the efflux transporter P-glycoprotein (P-gp).  In the clinical setting, the effects of 
vemurafenib on drugs that are substrates of P-gp and the effects of P-gp inducers and 
inhibitors on vemurafenib exposure are unknown.
Appendix 3 includes a non-exhaustive list of typical examples of CYP1A2, CYP3A4, and 
CYP2C9 substrates and CYP3A4 inducers and inhibitors.  A more extensive list of 
medications can be found online at the following link:  
http://medicine.iupui.edu/clinpharm/ddis/table.aspx.  For additional information, see the 
Vemurafenib IB.  If co-administration cannot be avoided, the physician should exercise 
caution and a dose reduction of the concomitant CYP1A2 or CYP2D6 substrate drug 
should be considered. 
4.4.4
Medications Affecting QT Interval
Certain medications could affect the results of QT intervals on ECG measurements 
required for this study.  Specifically, anti-emetics other than those belonging to the 
5-HT3 receptor antagonist class (i.e., granisetron, ondansetron, dolasetron, palanosetron) 
are preferred, because the latter has the potential to prolong the QTc interval 
(see Section 5.1.2.3).  Patients should avoid taking medications or herbal and vitamin 
supplements that may increase QTc interval, and investigators should closely monitor 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
36
patients who require taking these types of medications.  Alternative treatment options for 
medications known to affect the QT interval should be discussed with each patient prior
to their inclusion into this study.  A complete list of medications that may cause QT 
interval prolongation is provided in Appendix 4 .  Refer to http://www.azcert.org/ for 
additional information and references.

A complete physical examination will include the measurement of patients’ weight and 
height, as well as an evaluation of the head, eye, ear, nose, and throat and the 
cardiovascular, dermatological, musculoskeletal, respiratory, gastrointestinal, 
genitourinary, and neurological systems. 
At subsequent visits, limited, symptom-directed physical examinations and, at minimum, 
examination of the eyes and the cardiovascular and dermatological systems should be 
performed. 
New or worsened abnormalities should be recorded as adverse events on the Adverse 
Event eCRF.
As part of tumor assessments, physical examinations will include an evaluation of the 
presence of enlarged lymph nodes, hepatomegaly, and splenomegaly.  Some visits 
allow symptom-directed examinations (physical examinations relevant to the patient’s 
symptoms).  As part of each symptom-directed examination in this study, patients will be 
asked about skin and vision changes.
4.5.1.4
Tumor and Response Evaluations
Any evaluable and measurable disease will have been documented as specified for 
screening in the antecedent protocol and/or according to local institutional standards of 
care.  On-study tumor assessments will be done at the discretion of the investigator 
according to local institutional standard of care for purposes of the evaluation and 
definition of disease progression.

4.5.1.5
Performance Status
Performance status will be measured using the ECOG Performance Status scale (see 
Appendix 2).  It is recommended, where possible, that the same person assess a 
patient’s performance status throughout the study.  Refer to Appendix 1 for details on 
when ECOG Performance Status will be collected.
A window of 7 days of a scheduled study visit is allowed for the assessment of the 
ECOG Performance Status. 
4.5.1.6
Clinical Safety Assessments
NCI CTCAE v4.0 will be used to characterize the toxicity profile of the study treatment.  
All patients will be assessed for adverse events.  After signing the Informed Consent 
Form, all adverse events and serious adverse events (including serious adverse events 
due to invasive procedures required for the study, such as biopsies) will be collected.  
Patients will be assessed for adverse events at each study visit.  All adverse events will 
be recorded until 28 days after the last dose of study treatment or until initiation of 
another anti-cancer therapy, whichever occurs first.  
4.5.1.7
Laboratory Assessments
A series of laboratory assessments will be made throughout the course of this study.  
These assessments will be performed to monitor patient safety.
Normal ranges for the study laboratory parameters, where available, must be supplied to 
Roche/designee before the study starts. 
The laboratory assessments listed will be performed at a local laboratory:

Hematology:  WBC count, hemoglobin, hematocrit, platelet count, WBC differential 
count (neutrophils, bands, lymphocytes, eosinophils, basophils, and monocytes)

Serum chemistries:  sodium, potassium, chloride, bicarbonate, BUN, creatinine, 
calcium, phosphate, magnesium, total and direct bilirubin, albumin, AST, ALT, LDH, 
ALP

Serum pregnancy test (for women of childbearing potential including premenopausal 
women who have had a tubal ligation) within 7 days preceding planned first dose of 
vemurafenib 
4.5.1.8
Electrocardiograms
ECG recordings according local institutional standards will be obtained at each specified 
timepoint (see Appendix 1).  ECGs for each patient should be obtained from the same 
machine, whenever possible.  To minimize variability, it is important that patients be in a 
resting position for 10 minutes prior to each ECG evaluation.  Body position should be 
consistently maintained for each ECG evaluation to prevent changes in heart rate.  
Environmental distractions (e.g., television, radio, conversation) should be avoided 
during the pre-ECG resting period and during ECG recording.  ECGs should be 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
38
performed prior to any vital sign measurements and at least 15 minutes prior to blood 
draws scheduled to be performed on the same day.
For safety monitoring purposes, the investigator or designee must review, sign, and date 
all ECG tracings.  Paper copies will be kept as part of the patient’s permanent study file 
at the site.  ECG characteristics, including heart rate, QRS duration, and RR, PR, and 
QT intervals, will be monitored by the investigator.  If the patient experiences a Grade 3 
or Grade 4 QT prolongation (according to NCI CTCAE v4.0), the event should be 
recorded on the eCRF and reported as an expedited non-serious adverse event of 
special interest, including the QTc value.
4.5.1.9
Dermatologic and Squamous Cell Carcinoma Evaluations 
Regular dermatological evaluation to screen and monitor for cuSCC will be performed by 
a dermatologist or his/her designee with expertise in the diagnosis and management of 
cutaneous neoplasms.  A dermatological evaluation will be conducted at baseline (the 
most current examination from the antecedent protocol may be utilized as the screening 
examination for the extension [rollover] protocol if it was conducted within 30 days prior 
to first dose of vemurafenib on Study GO28399), at Cycles 2 and 3, and then every other 
cycle through Cycle 15.  Then, for patients still receiving study treatment, a 
dermatological evaluation will continue to be conducted every third cycle starting at 
Cycle 18 (i.e., screening and every three cycles per the Cycle 18period in the 
Schedule of Assessments [Appendix 1] for patients with 17 cycles of vemurafenib on 
an antecedent study), at the end of treatment visit, or until withdrawal of consent, death, 
or loss to follow-up (whichever occurs earliest). A window of 21 days from the 
scheduled study visit (with exception of the baseline evaluation) is allowed for 
completion of the dermatologic assessments cited above. 
Patients should see their physicians as needed for any new skin lesions while on the 
study drug.  An unscheduled dermatology examination may be done at any time during 
treatment, if clinically indicated.
Evaluations will include the following:

A complete history of prior dermatologic medications and cuSCC risk factors 
(i.e., radiation therapy, sun exposure, immunosuppression, prior SCC, use of 
tanning beds, precursor lesions, and phototherapy for psoriasis) must be collected.  
(Available information of dermatological history from the antecedent study can be 
used.)

A designated dermatologist or his/her designee will perform skin evaluations to 
monitor for SCC, primary melanoma, BCC, actinic keratosis, and KA. 

Any suspicious lesions identified from the screening period until 28 days after the 
completion of study treatment must be biopsied and/or excised and sent for 
pathologic examination.  Actinic keratosis, KA, or other skin conditions identified by 
the dermatologist should be treated per local standards of care.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
39

The occurrence of any skin changes, including rash and photosensitivity, should be 
reported to the study investigator for adequate adverse event reporting, and patients 
will be referred to the dermatologist as required.
4.5.1.10
Safety Surveillance for Squamous Cell Carcinoma
A thorough head and neck examination to monitor for non-cutaneous SCC, consisting of 
at least a visual inspection of the oral mucosa and lymph node palpation, must be 
performed by the treating physician or other qualified physician at screening for all 
patients enrolled.  The most current examination from the antecedent protocol may be 
utilized as the screening examination for the extension (rollover) protocol if it was 
conducted within 30 days prior to first dose of vemurafenib on Study GO28399. 
Thereafter, the head and neck examination will be repeated by the treating physician or 
other qualified physician every other treatment cycle (21 days) after initiation of study 
treatment and every other cycle through Cycle 15.  Then, for patients still receiving 
treatment, the head and neck examination will continue to be conducted every third
cycle starting at Cycle 18, (i.e., screening and every three cycles per the Cycle 18
period in the Schedule of Assessments [Appendix 1] for patients with 17 cycles of 
vemurafenib on an antecedent study), or until withdrawal of consent, death, or loss to 
follow-up (whichever occurs earliest). 
Chest CT scans must be performed at baseline, within 30 days before the start of study 
treatment on Study GO28399, and then every 6 months (with a window of 21 days) 
after the initiation of treatment until death, withdrawal of consent, or loss to follow-up, 
whichever occurs first.  Available routine chest CT scans from the antecedent study or 
those performed for tumor assessments during the study period (at the discretion of the 
investigator, per local institutional standard of care) that fit the required timeline 
specification can be used for this safety surveillance.   
Additionally, all patients are required to undergo examination of the anus by the treating 
physician or his/her designee at baseline and at the end of treatment visit.  The most 
current examination may be utilized as the baseline examination for the extension 
(rollover) protocol if it was conducted during the screening period or conduct of the 
antecedent protocol.
Female patients must have a pelvic examination (including evaluation of the uterine 
cervix and Papanicolaou [Pap] smear) at baseline and at the end of treatment visit 
performed by gynecologist or designee.  The most current examination may be utilized 
as the screening examination for the extension (rollover) protocol if it was conducted 
during the screening period or the conduct of the antecedent protocol.
4.5.1.11
Exploratory Molecular Assessments

Patient specimens for dynamic (non-inherited) biomarker discovery and validation 
should be collected from patients participating in this study if the sample is available 
by routine biopsy.

Epidermal growth factor receptor (EGFR) expression/gene copy number
At least 610 formalin-fixed paraffin embedded tissue slides are required.
4.5.2
Timing of Study Assessments
4.5.2.1
Screening/Baseline and Pretreatment Assessments
Written informed consent for participation in the study must be obtained before 
performing any study-specific baseline tests or evaluations.  Informed Consent Forms for 
enrolled patients and for patients who are not subsequently enrolled will be maintained 
at the study site.  
The investigator must maintain a patient Enrollment and Identification Code List.
Results from the study completion visit or other prior visit assessment in the antecedent 
protocol may be used as screening/baseline for this extension (rollover) study, if within 
time intervals, as specified in this section and Appendix 1; screening/baseline is 
combined into one visit.
Under no circumstance will patients be permitted to re-enroll in the study if they have 
previously enrolled in this study and completed/discontinued treatment as specified.
All required screening/baseline procedures including data collection or transfer from the 
antecedent study must be performed after the patient has provided informed consent 
within a maximum window of 15 days from the last dose of study drug in the antecedent 
study to until the first dose of treatment in this extension (rollover) study, or as specified 
in Section 4.5.1 and Appendix 1 for specific assessments.
All patients will be closely monitored for safety and tolerability during all cycles of therapy 
and at the study completion visit.  After signing the Informed Consent Form, all adverse 
events and serious adverse events (including serious adverse events due to invasive 
procedures required for the study such as biopsies) will be collected.  Patients will be 
assessed for adverse events prior to each subsequent cycle and as necessary 
throughout the study.  All adverse events will be recorded until 28 days after the last 
dose of study treatment or until initiation of another anti-cancer therapy, whichever 
occurs first. 
Visits are based on a 28-day cycle.  If the timing of a protocol-mandated procedure 
coincides with a holiday or another scheduling conflict that precludes the visit, the visit 
should be scheduled within 3 days of the date in question, which may be earlier or later.

Refer to Appendix 1 for assessments to be performed at the study completion or early 
termination visit.
4.5.2.5
Adverse Event Follow-Up
After the study completion visit, ongoing adverse events thought to be related to study 
treatment will be followed until the event has resolved to baseline grade, is assessed by 
the investigator as stable, new anti-tumor treatment is initiated, the patient is lost to 
follow-up, the patient withdraws consent, or it has been determined that study treatment 
or participation is not the cause of the adverse events.
After the study completion visit, investigators should report only serious adverse events 
that are deemed related to study treatment.  
After the study completion/early termination visit, adverse events should be followed as 
outlined in Sections 5.5 and 5.6.
See Appendix 1 for the schedule of follow-up assessments.
4.5.3
Patient Discontinuation
The investigator has the right to discontinue a patient from study drug or withdraw a 
patient from the study at any time.  In addition, patients have the right to voluntarily 
discontinue study drug or withdraw from the study at any time for any reason.  Reasons 
for discontinuation of study drug or withdrawal from the study may include but are not 
limited to the following:

Patient withdrawal of consent at any time

Any medical condition that the investigator or Sponsor determines may jeopardize 
the patient’s safety if he or she continues in the study

Investigator or Sponsor determines it is in the best interest of the patient.

Patient non-compliance, specifically defined as patient’s refusal to take the required 
doses of study drugs, unless for a reason, as defined below
In cases where the patient decides to prematurely discontinue study treatment (“refuses 
treatment”), he or she should be asked if he or she can still be contacted for further 
information.  The outcome of that discussion should be documented in both the medical 
records and in the eCRF.  If the patient is lost to follow-up, the investigator should 
contact the patient or a responsible relative by telephone followed by registered mail to 
establish the reason for the withdrawal as completely as possible.  A complete final 
evaluation at the time of the patient’s withdrawal should be made with an explanation of 
why the patient is withdrawing from the study.
When applicable, patients should be informed of circumstances under which their 
participation may be terminated by the investigator without the patient’s consent.  The
investigator may withdraw patients from the study in the event of intercurrent illness, 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
45
adverse events, treatment failure after a prescribed procedure, lack of compliance with 
the study and/or study procedures (e.g., dosing instructions, study visits), cure, or any 
reason where it is believed by the investigator that it is in the best interest of the patient 
to be terminated from the study.  Any administrative or other reasons for withdrawal 
must be documented and explained to the patient.  Any patient who discontinues will be 
encouraged to return to the study center for a study completion visit. 
4.5.3.1
Discontinuation from Study Drug
Patients may continue to receive treatment with vemurafenib until disease progression 
(as defined by the investigator, according local institutional standard of care), 
unacceptable toxicity, or any other discontinuation criterion is met, as follows, whichever 
occurs first.

Disease progression as assessed per institutional standards of care 
Progressive disease during the antecedent protocol.  If approval to treat beyond 
progression was already given in the antecedent protocol, the patient may roll 
over into the current protocol. 
Under special circumstances, when it is believed that the patient may clinically 
benefit from continued therapy with vemurafenib (e.g., in case of mixed 
progression or progression of single lesion or appearance of a new single 
lesion), enrollment into this protocol and dosing beyond progression may be 
considered if it is judged by the investigator, in consultation with the Sponsor, to 
be in the best interest of the patient.  All such cases will require approval of the 
Sponsor before continuing study drug treatment within this protocol.

Intolerance of vemurafenib

If treatment is suspended more than 28 days, the patient should be withdrawn from 
the study

Initiation of other cancer medication

Pregnancy
Patients who discontinue study drug prematurely will be asked to return to the clinic for 
an end of treatment visit (see Section 4.5.2.4 and Appendix 1).  The primary reason for 
premature study drug discontinuation should be documented on the appropriate eCRF.  
Patients who discontinue study drug prematurely will not be replaced.
All patients who discontinue vemurafenib treatment will be followed for safety 
surveillance per the investigator’s discretion. 
Note: New primary melanomas identified as part of the dermatologic risk management 
plan outlined in Section 4.5.1.9, which are completely excised and without need for 
additional therapy, do not require patient discontinuation from study treatment.

4.5.3.2
Withdrawal from Study
Every effort should be made to obtain information on patients who withdraw from the 
study.  The primary reason for withdrawal from the study should be documented on the 
appropriate eCRF.  Patients will not be followed for any reason after consent has been 
withdrawn.  Patients who withdraw from the study will not be replaced.
4.5.4
Study and Site Discontinuation
The Sponsor has the right to terminate this study at any time.  Reasons for terminating 
the study may include but are not limited to the following:

The incidence or severity of adverse events in this or other studies indicates a 
potential health hazard to patients.

Patient enrollment is unsatisfactory.

All enrolled patients have discontinued study treatment.
The Sponsor will notify the investigator if the study is placed on hold or if the Sponsor 
decides to discontinue the study or development program.  
The Sponsor has the right to replace a site at any time.  Reasons for replacing a site 
may include but are not limited to the following:

Poor protocol adherence

ASSESSMENT OF SAFETY
5.1
SAFETY PLAN
Measures will be taken to ensure the safety of patients participating in this trial; in 
particular, the use of inclusion and exclusion criteria and close monitoring of patients.
5.1.1
Risks Associated with Vemurafenib
The toxicity profile for vemurafenib has been documented from safety data derived 
from seven studies of more than 600 treated patients with locally advanced unresectable 
or metastatic melanoma.  The most common toxicities observed were rash, fatigue, 
arthralgia, myalgia, headache, nausea, photosensitivity, alopecia, and pruritus.  The 
most common laboratory abnormalities reported as adverse events included elevations 
of liver function tests (i.e., GGT, ALP, ALT, AST, and bilirubin).  The majority of adverse 
events reported in conjunction with Phase I to III clinical trials were of mild or moderate 
severity.  Approximately one-half of all patients treated with vemurafenib required 
interruption and/or reduction of dose on at least one occasion, although treatment 
discontinuation due to adverse events has been rare.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
47
Approximately 20% of vemurafenib recipients developed one or more localized, 
cutaneous SCCs (mainly KA type).  The majority of SCCs were observed within the first 
16 weeks of vemurafenib exposure and were not treatment limiting.  
Eight cases of skin lesions in 7 vemurafenib-treated patients were reported as new 
primary malignant melanomas in Study NO25026. No cases were reported in patients 
treated with dacarbazine. Cases were managed with excision, and patients continued 
treatment without dose adjustment. Surveillance measures to monitor for the 
occurrence of new primary melanomas, SCC (cutaneous and non-cutaneous), and any 
new primary malignancies are outlined in Section 4.5.1.9.
Two cases of SCC of the head and neck have been reported in 2 patients treated with 
vemurafenib in excess of 300 days while enrolled in a clinical trial.  Pathology 
examination of both tumors (one a primary tonsillar tumor, the other a primary tongue 
tumor) revealed the presence of invasive SCC.  Of note, the first patient’s medical 
history was significant for risk factors for head and neck cancer and the tumor tissue 
tested positive for HPV.  The second patient does not appear to possess any risk factors 
for head and neck cancer, and the preliminary examination of the tumor tissue did not 
reveal the presence of HPV genome.  Full details are provided in the current 
Vemurafenib IB.
Five cases of adenomatous colonic polyps have been reported in patients who received 
vemurafenib for more than 2 years, and 1 patient in the Expanded Access Program had 
one colonic adenoma discovered after treatment with vemurafenib for 0.57 years 
(Chapman et al. 2012).
Analysis of ECG data from the Phase II Study NP22657 of vemurafenib in previously 
treated patients with metastatic melanoma revealed a risk of QT interval prolongation 
without associated clinical symptomatology. 
See Section 1.2.1.5 and the Vemurafenib IB for more details.
5.1.2
General Plan to Manage Safety Concerns
5.1.2.1
Eligibility Criteria
Eligibility criteria exclude patients who previously discontinued vemurafenib for any 
reason in an antecedent protocol or who met an exclusion criterion, as specified in the 
antecedent study or the extension (rollover) protocol.
5.1.2.2
Monitoring
Safety will be evaluated in this study through the monitoring of all adverse events and 
targeted laboratory assessments according to NCI CTCAE v4.0.  Patients will be 
monitored on Day 1 of every subsequent cycle and as needed until 28 days after the last 
dose of study treatment or initiation of other anti-cancer therapy, whichever occurs first.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
48
All treatment-emergent adverse events and serious adverse events, whether or not 
deemed treatment related, will be followed until they resolve or become stabilized, the 
patient is lost to follow-up or withdraws consent, or it has been determined that the study 
treatment or participation is not the cause of the adverse event or serious adverse event.  
General safety assessments will include serial interval histories, physical examinations,
and specific laboratory studies including serum chemistries, liver function tests, and 
blood counts.
All serious adverse events and protocol-defined adverse events of special interest (see 
Section 5.4.2) will be reported in an expedited fashion.
5.1.2.3
Monitoring and Management of Specific Toxicities and 
Conditions That May Arise with Treatment with Vemurafenib 
Non-Squamous Cell Carcinoma Skin Toxicity
The non-SCC skin toxicities observed in patients treated with vemurafenib include rash, 
pruritus, palmar-plantar erythrodysesthesia, dry skin, and exfoliation.  Of these, the most 
common has been rash (maculopapular or acneiform), which has generally been 
manageable with supportive care.  Skin toxicities other than lesions suspected of being 
cuSCC will be managed with supportive care according to institutional guidelines as well 
as by dose interruption/modification, as specified in Section 5.1.2.3.
Mild to severe photosensitivity has been reported in patients who received vemurafenib 
in clinical studies.  All patients should be advised to avoid sun exposure while taking the 
study drug.  Patients should be advised to wear protective clothing and use a broad 
spectrum UVA/UVB sunscreen and lip balm (sun protection factor 30) when outdoors 
to help protect against sunburn.  For photosensitivity Grade 2 (intolerable) adverse 
reactions, dose modifications will be required (see Section 5.1.2.3).
Management and Safety Surveillance for Cutaneous Squamous Cell 
Carcinoma and New Primary Melanoma
If a patient develops cuSCC during the study, this information must be collected and 
reported as a non-serious adverse event of special interest to the Sponsor, whether it is 
deemed related or unrelated to study drug.  
If a patient develops a new primary melanoma during the study, this information must be 
collected and reported as a non-serious adverse event of special interest to the Sponsor, 
whether it is deemed related or unrelated to study drug.  An unscheduled dermatologic 
examination may be performed during treatment for investigation of any new suspicious 
skin lesions.
Confirmed cuSCC and/or new primary melanoma should be completely resected and 
treated according local institutional standard of care.  Vemurafenib treatment interruption 
and/or dose modifications are not recommended (see Section 5.1.2.3). 
See Section 4.5.1.9 for more details.

Management and Safety Surveillance for Non-Cutaneous Squamous Cell 
Carcinoma:

A thorough head and neck examination to monitor for non-cutaneous SCC, 
consisting of at least a visual inspection of the oral mucosa and lymph node 
palpation, must be performed by the treating physician or other qualified physician 
at screening for all patients enrolled.  The most current examination from the 
antecedent protocol may be utilized as the screening examination for the extension 
(rollover) protocol if it was conducted within 30 days prior to the first dose of 
vemurafenib.  Subsequent head and neck examinations will be performed as 
outlined in Section 4.5.1.10.

Chest CT scans must be performed at baseline, within 30 days before the start of 
study treatment and then every 6 months (with a window of 21 days) after initiation 
of treatment until death, withdrawal of consent, or loss to follow-up, whichever 
occurs first.  Available routine chest CT scans from previous assessments may be 
used, as outlined in Section 4.5.1.10.

Additionally, all patients are required to undergo examination (visual and digital) of 
the anus and anal canal by the treating physician or his/her designee at baseline 
and at the end of the study (end of treatment visit).  The most current examination
from the antecedent protocol may be used, as outlined in Section 4.5.1.10.

Female patients must have a pelvic examination (including evaluation of the uterine 
cervix by Pap smear) at baseline and at the end of the study (end of treatment visit), 
performed by a gynecologist or designee.  The most current examination from the 
antecedent protocol may be used, as outlined in Section 4.5.1.10.

An unscheduled examination may be performed during treatment for the 
investigation of any new lesion or symptom suspected to be SCC (head and neck, 
anus, pelvic for female patients only, chest CT).
New Primary Invasive Malignancies
All new primary invasive malignancies will be reported until 28 days after treatment 
completion, withdrawal of consent, loss to follow-up, or death, whichever occurs earliest.
If a patient develops a new primary invasive malignancy during or up to 28 days after 
study treatment completion, this event must be reported to the Sponsor as a serious 
adverse event, whether it is deemed related or unrelated to study drug.  Thereafter, only 
new primary malignancies thought to be related to study treatment will be reported as 
serious adverse events.
Any identified lesion suspected to be a new primary malignancy (including cuSCC, 
non-cutaneous SCC, and/or new primary melanoma) must be biopsied or excised and 
sent for pathological examination and should be treated according local institutional 
standard of care.

Hepatic Toxicity
Cases of liver injury, including severe cases of liver injury, have been reported with 
vemurafenib use.  These have been generally managed with interruption of treatment 
and dose reduction.  All patients will undergo liver function testing at periodic intervals 
while on study treatment (see Appendix 1).  Guidelines for interruption or dose reduction 
of vemurafenib in the setting of liver function abnormality are provided in Section 5.1.3.
See also the Vemurafenib IB for updated safety information.
Hematologic Toxicity
Patients will have hematologic parameters monitored throughout the study.  See the 
Vemurafenib IB for full details of potential hematologic adverse events reported in 
association with vemurafenib treatment.
Gastrointestinal Toxicity
Gastrointestinal toxicities will be managed according to institutional guidelines/standard 
of care.  During the study, patients are to receive maximal supportive care as clinically 
indicated.  Any modification of study treatment for diarrhea must strictly follow the 
instructions in Table 1.
Pancreatic Toxicity
The Sponsor recommends that workup of any suspected case of pancreatitis should 
include serum amylase and lipase testing, in addition to other appropriate testing 
(e.g., CT abdomen).
Ocular Toxicity
See the Vemurafenib IB for further details on the occurrence of anterior uveitis and a 
single case of retinal vein occlusion reported in association with vemurafenib treatment.
Examination of the eyes (inspection of conjunctivae and pupils) is part of the physical 
examination.  
Cardiac Toxicity
Patients with a baseline QTc 450 ms or a history of congenital long QT syndrome 
should not receive treatment with vemurafenib.  Refer to the Vemurafenib IB for 
additional details.
The following recommendations have been developed to minimize the risk of cardiac 
toxicity in patients with metastatic melanoma treated with vemurafenib in this study:

Avoid combination with other medications with known potential to lead to 
prolongation of the QTc interval, if possible (see Appendix 4)

ECG monitoring will occur at baseline and at specified intervals, as outlined in the 
Schedule of Assessments (see Appendix 1).


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
51

If the QTc increases to 500 ms, or if a change from baseline of 60 ms is 
observed during the study, vemurafenib treatment should be temporarily interrupted.  
Electrolytes (K, Mg, albumin, and Ca) should be monitored, and any electrolyte 
abnormalities, especially hypokalemia, should be corrected prior to re-institution of 
therapy.  ECG should be monitored weekly until the QTc normalizes before therapy 
is reinstituted at a reduced dose.  Dose reduction should occur as described in 
Table 1.  A second sustained occurrence of QTc interval prolongation to 500 ms,
despite dose reduction, will require discontinuation of vemurafenib.

Vemurafenib treatment should be permanently discontinued if the QTc increases to
500 ms and changes from baseline exceed 60 ms.
5.1.3
Dose Interruption/Modification for Adverse Events
If a dose is missed, it can be taken 4 or more hours before the next dose to maintain the 
twice-daily regimen.  Both doses should not be taken at the same time.
Management of symptomatic adverse drug reactions (e.g., arthralgia, fatigue, rash) may 
require either temporary interruption or dose reduction of vemurafenib treatment or both.  
When dose reduction is needed, dose reduction in 240-mg BID increments is 
recommended depending on individual safety and tolerability.  Dose escalation after 
dose reduction is generally not recommended unless under special circumstances 
(i.e., increased likelihood of clinical benefit for the dose increase and no safety concerns).  
This should be done after discussion with the Sponsor.  Dose increases above 960 mg 
BID will not be allowed. 
For Grade 1 and tolerable Grade 2 toxicities, patients may continue with the full dose.  
For intolerable Grade 2 toxicities or Grade 3 toxicities, dosing will be interrupted until 
resolution to Grade 1 or lower and dose reductions in 240-mg increments are required.  
On the third appearance of intolerable Grade 2 or Grade 3 toxicity, despite two dose 
reductions, it is recommended that patients discontinue vemurafenib. 
For Grade 4 toxicities, patients should discontinue study treatment or, on the basis of 
investigator judgment, study treatment should be interrupted until resolution to Grade 1
or lower with dose reduction of 50% upon restarting study drug.  It is recommended that 
patients permanently discontinue vemurafenib for a second occurrence of any Grade 4 
toxicities.
If treatment interruption has occurred for 28 days for whatever reason, the patient will 
be considered to have permanently discontinued study treatment.  Exceptions may be 
granted for reversible laboratory abnormalities with no clinical sequelae and/or clinical 
significance following consultation with the study’s Medical Monitor.  See Table 1 below.

Special consideration must be taken with any patient in the study who experiences an 
increase in QTc 500 ms or change from baseline 60 ms.  If the QTc exceeds 500 ms 
or the change from baseline is 60 ms on ECG, vemurafenib treatment should be 
temporarily interrupted.  When the QTc decreases to 500 ms, re-initiation of 
vemurafenib treatment may occur and the dose should be reduced by one dose level.  
Permanent discontinuation of vemurafenib treatment is recommended if the QTc 
increase meets both criteria of 500 ms and 60 ms change from pretreatment.
Dose modifications or interruptions are not recommended for cuSCC or new primary 
melanoma adverse reactions (suspected lesion should be biopsied or resected and 
confirmed by pathology).  Confirmed cuSCC or new primary melanoma should be 
completely resected and treated according local institutional standard of care.
5.2
SAFETY PARAMETERS AND DEFINITIONS
Safety assessments will consist of monitoring and recording adverse events, including 
serious adverse events and non-serious adverse events of special interest,
measurement of protocol-specified clinical laboratory assessments, measurement of
protocol-specified vital signs, and other protocol-specified tests that are deemed critical 
to the safety evaluation of the study.
Certain types of events require immediate reporting to the Sponsor, as outlined in 
Section 5.4.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
53
5.2.1
Adverse Events
According to the ICH guideline for GCP, an adverse event is any untoward medical 
occurrence in a clinical investigation subject administered a pharmaceutical product, 
regardless of causal attribution.  An adverse event can therefore be any of the following:

Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medicinal product, 
whether or not considered related to the medicinal product

Any new disease or exacerbation of an existing disease (a worsening in the 
character, frequency, or severity of a known condition), except as described in 
Section 5.3.5.9

Recurrence of an intermittent medical condition (e.g., headache) not present at 
baseline

Any deterioration in a laboratory value or other clinical test (e.g., ECG, X-ray) that is 
associated with symptoms or leads to a change in study treatment or concomitant 
treatment or discontinuation from study drug

Adverse events that are related to a protocol-mandated intervention, including those 
that occur prior to assignment of study treatment (e.g., screening invasive 
procedures such as biopsies)
5.2.2
Serious Adverse Events (Immediately Reportable to Roche)
A serious adverse event is any adverse event that meets any of the following criteria:

Fatal (i.e., the adverse event actually causes or leads to death)

Life-threatening (i.e., the adverse event, in the view of the investigator, places the 
patient at immediate risk of death)
This does not include any adverse event that, had it occurred in a more severe 
form or was allowed to continue, might have caused death.

Requires or prolongs inpatient hospitalization (see Section 5.3.5.10)

Results in persistent or significant disability or incapacity (i.e., the adverse event
results in substantial disruption of the patient’s ability to conduct normal life 
functions)

Congenital anomaly or birth defect in a neonate or infant born to a mother exposed 
to the study drug

Significant medical event in the investigator's judgment (e.g., may jeopardize the 
patient or may require medical or surgical intervention to prevent one of the 
outcomes listed above)
A new primary invasive malignancy (other than cuSCC or new primary melanoma) or 
progression or recurrence of a prior invasive malignancy (other than the disease under 
study) will be characterized as a serious adverse event.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
54
The terms “severe” and “serious” are not synonymous.  Severity refers to the intensity of 
an adverse event (rated as mild, moderate, or severe or according to NCI CTCAE 
criteria; see Section 5.3.3); the event itself may be of relatively minor medical 
significance (such as severe headache without any further findings).
Severity and seriousness need to be independently assessed for each adverse event 
recorded on the eCRF.
Serious adverse events are required to be reported by the investigator to the Sponsor 
within 24 hours after learning of the event (see Section 5.4.2 for reporting instructions).
5.2.3
Adverse Events of Special Interest (Immediately Reportable to 
Roche)
Adverse events of special interest are required to be reported by the investigator to the 
Sponsor within 24 hours after learning of the event (see Section 5.4.2 for reporting 
instructions).  Adverse events of special interest for this study include the following:

Cases of potential drug-induced liver injury that include an elevated ALT or AST 
in combination with either an elevated bilirubin or clinical jaundice, as defined by 
Hy's Law (see Section 5.3.5.6)

Suspected transmission of an infectious agent by the study drug, as defined below
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.

Grade 3 or 4 QTc interval prolongation

cuSCC

New primary melanoma
5.3
METHODS AND TIMING FOR CAPTURING AND ASSESSING 
SAFETY PARAMETERS
The investigator is responsible for ensuring that all adverse events (see Section 5.2.1 for 
definition) are recorded on the Adverse Event eCRF and reported to the Sponsor in 
accordance with instructions provided in this section and in Sections 5.45.6.
For each adverse event recorded on the Adverse Event eCRF, the investigator will make 
an assessment of seriousness (see Section 5.2.2 for seriousness criteria), severity (see 
Section 5.3.3), and causality (see Section 5.3.4).
Adverse events still ongoing or not resolved at the time of enrollment in the extension 
(rollover) study should be recorded on the Adverse Event eCRF, as specified in the 
protocol, with the original onset date from the antecedent study.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
55
5.3.1
Adverse Event Reporting Period
Investigators will seek information on adverse events at each patient contact.  All 
adverse events, whether reported by the patient or noted by study personnel, will be 
recorded in the patient’s medical record and on the Adverse Event eCRF.
After informed consent has been obtained but prior to initiation of study drug, only 
serious adverse events caused by a protocol-mandated intervention should be reported 
(e.g., serious adverse events related to invasive procedures such as biopsies).
After initiation of study drug, all adverse events, regardless of relationship to study drug, 
will be reported until 28 days after the last dose of study treatment or until initiation of 
another anti-cancer therapy, whichever comes first.  
Instructions for reporting adverse events that occur after the adverse event reporting 
period are provided in Section 5.6.
5.3.2
Eliciting Adverse Event Information
A consistent methodology of non-directive questioning should be adopted for eliciting 
adverse event information at all patient evaluation timepoints.  Examples of non-directive 
questions include the following:
“How have you felt since your last clinic visit?”
“Have you had any new or changed health problems since you were last here?” 
5.3.3
Assessment of Severity of Adverse Events
The adverse event severity grading scale for the NCI CTCAE v4.0 will be used for 
assessing adverse event severity. Table 2 will be used for assessing severity for 
adverse events that are not specifically listed in the NCI CTCAE.

clothes, using the telephone, managing money, etc.
b Examples of self-care activities of daily living include bathing, dressing and undressing, 
feeding one's self, using the toilet, and taking medications, as performed by patients who 
are not bedridden.
c If an event is assessed as a "significant medical event," it must be reported as a serious 
adverse event (see Section 5.4.2 for reporting instructions), per the definition of serious 
adverse event in Section 5.2.2.
d Grade 4 and 5 events must be reported as serious adverse events (see Section 5.4.2 for 
reporting instructions), per the definition of serious adverse event in Section 5.2.2.
5.3.4
Assessment of Causality of Adverse Events
Investigators should use their knowledge of the patient, the circumstances surrounding 
the event, and an evaluation of any potential alternative causes to determine whether or 
not an adverse event is considered to be related to the study drug, indicating "yes" or 
"no" accordingly.  The following guidance should be taken into consideration:

Temporal relationship of event onset to the initiation of study drug

Course of the event, considering especially the effects of dose reduction, 
discontinuation of study drug, or reintroduction of study drug (where applicable)

Known association of the event with the study drug or with similar treatments

Known association of the event with the disease under study

Presence of risk factors in the patient or use of concomitant medications known to 
increase the occurrence of the event

Presence of nontreatment-related factors that are known to be associated with the 
occurrence of the event


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
57
For patients receiving combination therapy, causality will be assessed individually for 
each protocol-mandated therapy.
5.3.5
Procedures for Recording Adverse Events
Investigators should use correct medical terminology and concepts when recording 
adverse events on the Adverse Event eCRF.  Colloquialisms and abbreviations should 
be avoided.
Only one adverse event term should be recorded in the event field on the Adverse Event 
eCRF.
5.3.5.1
Diagnosis versus Signs and Symptoms
For adverse events, a diagnosis (if known) should be recorded on the Adverse Event 
eCRF 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, each individual event should be recorded 
on the Adverse Event eCRF.  If a diagnosis is subsequently established, all previously 
reported adverse events based on signs and symptoms should be nullified and replaced 
by one adverse event report based on the single diagnosis, with a starting date that 
corresponds to the starting date of the first symptom of the eventual diagnosis.
5.3.5.2
Adverse Events Occurring Secondary to Other Events
In general, adverse events occurring secondary to other events (e.g., cascade events or 
clinical sequelae) should be identified by their primary cause, with the exception of 
severe or serious secondary events.  However, medically significant adverse events
occurring secondary to an initiating event that are separated in time should be recorded 
as independent events on the Adverse Event eCRF.  For example:

If vomiting results in mild dehydration with no additional treatment in a healthy adult, 
only vomiting should be reported on the eCRF.

If vomiting results in severe dehydration, both events should be reported separately 
on the eCRF.

If a severe gastrointestinal hemorrhage leads to renal failure, both events should be 
reported separately on the eCRF.

If dizziness leads to a fall and subsequent fracture, all three events should be 
reported separately on the eCRF.

If neutropenia is accompanied by a mild, non-serious infection, only neutropenia 
should be reported on the eCRF.

If neutropenia is accompanied by a severe or serious infection, both events should 
be reported separately on the eCRF.
All adverse events should be recorded separately on the Adverse Event eCRF if it is 
unclear as to whether the events are associated.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
58
5.3.5.3
Persistent or Recurrent Adverse Events
A persistent adverse event is one that extends continuously, without resolution, between 
patient evaluation timepoints.  Such events should only be recorded once on the 
Adverse Event eCRF.  The initial severity (intensity or grade) of the event will be 
recorded at the time the event is first reported.  If a persistent adverse event becomes 
more severe, the most extreme severity should also be recorded on the Adverse Event 
eCRF.  If the event becomes serious, it should be reported to the Sponsor immediately 
(i.e., no more than 24 hours after learning that the event became serious; see 
Section 5.4.2 for reporting instructions).  The Adverse Event eCRF should be updated 
by changing the event from "non-serious" to "serious," providing the date that the 
event became serious, and completing all data fields related to serious adverse events.
A recurrent adverse event is one that resolves between patient evaluation timepoints 
and subsequently recurs.  Each recurrence of an adverse event should be recorded 
separately on the Adverse Event eCRF.
5.3.5.4
Abnormal Laboratory Values
Not every laboratory abnormality qualifies as an adverse event.  A laboratory test result 
should be reported as an adverse event if it meets any of the following criteria:

Accompanied by clinical symptoms

Results in a change in study treatment (e.g., dosage modification, treatment 
interruption, or treatment discontinuation)

Results in a medical intervention (e.g., potassium supplementation for hypokalemia) 
or a change in concomitant therapy

Clinically significant in the investigator’s judgment 
It is the investigator’s responsibility to review all laboratory findings.  Medical and 
scientific judgment should be exercised in deciding whether an isolated laboratory 
abnormality should be classified as an adverse event.
If a clinically significant laboratory abnormality is a sign of a disease or syndrome 
(e.g., ALP and bilirubin 5 times the upper limit of normal [ULN] associated with 
cholecystitis), only the diagnosis (i.e., cholecystitis) should be recorded on the Adverse 
Event eCRF.
If a clinically significant laboratory abnormality is not a sign of a disease or syndrome, 
the abnormality itself should be recorded on the Adverse Event eCRF, along with a 
descriptor indicating if the test result is above or below the normal range (e.g., "elevated 
potassium," as opposed to "abnormal potassium").  If the laboratory abnormality can be 
characterized by a precise clinical term per standard definitions, the clinical term should 
be recorded as the adverse event.  For example, an elevated serum potassium level of 
7.0 mEq/L should be recorded as “hyperkalemia.”


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
59
Observations of the same clinically significant laboratory abnormality from visit to visit 
should not be repeatedly recorded on the Adverse Event eCRF, unless the etiology 
changes.  The initial severity of the event should be recorded, and the severity or 
seriousness should be updated any time the event worsens.
5.3.5.5
Abnormal Vital Sign Values
Not every vital sign abnormality qualifies as an adverse event.  A vital sign result should 
be reported as an adverse event if it meets any of the following criteria:

Accompanied by clinical symptoms

Results in a change in study treatment (e.g., dosage modification, treatment 
interruption, or treatment discontinuation)

Results in a medical intervention or a change in concomitant therapy

Clinically significant in the investigator’s judgment 
It is the investigator’s responsibility to review all vital sign findings.  Medical and scientific 
judgment should be exercised in deciding whether an isolated vital sign abnormality 
should be classified as an adverse event.
If a clinically significant vital sign abnormality is a sign of a disease or syndrome 
(e.g., high blood pressure), only the diagnosis (i.e., hypertension) should be recorded on 
the Adverse Event eCRF.
Observations of the same clinically significant vital sign abnormality from visit to visit 
should not be repeatedly recorded on the Adverse Event eCRF, unless the etiology 
changes.  The initial severity of the event should be recorded, and the severity or 
seriousness should be updated any time the event worsens.
5.3.5.6
Abnormal Liver Function Tests
The finding of an elevated ALT or AST (3ULN) in combination with either an elevated 
total bilirubin (2ULN) or clinical jaundice in the absence of cholestasis or other 
causes of hyperbilirubinemia is considered to be an indicator of severe liver injury.  
Therefore, investigators must report as an adverse event of special interest the 
occurrence of either of the following:

Treatment-emergent ALT or AST 3ULN in combination with total bilirubin
2ULN

Treatment-emergent ALT or AST 3ULN in combination with clinical jaundice
The most appropriate diagnosis or (if a diagnosis cannot be established) the abnormal 
laboratory values should be recorded on the Adverse Event eCRF (see Section 5.3.5.1) 
and reported to the Sponsor within 24 hours after learning of the event, either as a 
serious adverse event or a non-serious adverse event of special interest (see 
Section 5.4.2).

5.3.5.7
Deaths
Deaths that occur during the protocol-specified adverse event reporting period (see 
Section 5.3.1) that are attributed by the investigator solely to recurrence of the 
underlying malignancy should be recorded only on the Study Completion/Early 
Discontinuation eCRF.  All other on-study deaths, regardless of relationship to study 
drug, must be recorded on the Adverse Event eCRF and immediately reported to the 
Sponsor (see Section 5.4.2).
Death should be considered an outcome and not a distinct event.  The event or condition 
that caused or contributed to the fatal outcome should be recorded as the single medical 
concept on the Adverse Event eCRF.  Generally, only one such event should be 
reported.  If the cause of death is unknown and cannot be ascertained at the time of 
reporting, "unexplained death" should be recorded on the Adverse Event eCRF.  If the 
cause of death later becomes available (e.g., after autopsy), "unexplained death" should 
be replaced by the established cause of death.  The term "sudden death" should not be 
used unless combined with the presumed cause of death (e.g., "sudden cardiac death").
If the death is attributed to progression of the underlying malignancy, this should not be 
recorded on the Adverse Event eCRF but should be captured in the Death and Disease 
Progression/Final Treatment Visit eCRFs.  
Deaths that occur after the adverse event reporting period should be reported as 
described in Section 5.6.
The study will comply with all local regulatory requirements and adhere to the full 
requirements of the ICH Guideline for Clinical Safety Data Management, Definitions and 
Standards for Expedited Reporting, Topic E2 (see Appendix 5).
5.3.5.8
Preexisting Medical Conditions
A preexisting medical condition is one that is present at the baseline/screening visit for 
this study.  Such conditions should be recorded on the General Medical History and 
Baseline Conditions eCRF (see Appendix 1).
A preexisting medical condition should be recorded as an adverse event only if the 
frequency, severity, or character of the condition worsens during the study.  When 
recording such events on the Adverse Event eCRF, it is important to convey the 
concept that the preexisting condition has changed by including applicable descriptors 
(e.g., more frequent headaches”).
5.3.5.9
Worsening of Malignancy
Events that are clearly consistent with the expected pattern of progression of the 
underlying disease should not be recorded as adverse events.  In most cases, the 
expected pattern of progression will be based on Response Evaluation Criteria in Solid 
Tumors (RECIST) criteria.  In rare cases, the determination of clinical progression will 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
61
be based on symptomatic deterioration.  However, every effort should be made to 
document progression with use of objective criteria.  If there is any uncertainty as to 
whether an event is due to disease progression, it should be reported as an adverse 
event.
5.3.5.10
Hospitalization or Prolonged Hospitalization
Any adverse event that results in hospitalization or prolonged hospitalization should be 
documented and reported as a serious adverse event (per the definition of serious 
adverse event in Section 5.2.2), except as outlined below.  
An event that leads to hospitalization under the following circumstances should not be 
reported as an adverse event or a serious adverse event:

Hospitalization for respite care

Hospitalization for a preexisting condition, provided that all of the following criteria 
are met:
The hospitalization was planned prior to the study or was scheduled during the 
study when elective surgery became necessary because of the expected 
normal progression of the disease.
The patient has not suffered an adverse event.
Hospitalization due solely to progression of the underlying cancer
An event that leads to hospitalization under the following circumstances is not 
considered to be a serious adverse event, but should be reported as an adverse event 
instead:

Elective hospitalizations or surgical procedures that are a result of a patient’s 
preexisting condition(s) that have not worsened since receiving trial medication.  
Examples may include but are not limited to cholecystectomy for gallstones, joint 
replacement surgery, and diagnostic testing.  Such events should still be recorded 
as medical procedures in the eCRF.
5.3.5.11
Overdoses
Study drug overdose is the accidental or intentional use of the drug in an amount higher 
than the dose being studied.  An overdose or incorrect administration of study drug is not 
an adverse event unless it results in untoward medical effects.  
Any study drug overdose or incorrect administration of study drug should be noted on 
the Study Drug Administration eCRF. 
All adverse events associated with an overdose or incorrect administration of study drug 
should be recorded on the Adverse Event eCRF.  If the associated adverse event fulfills 
serious criteria, the event should be reported to the Sponsor within 24 hours after 
learning of the event (see Section 5.4.2).

Committee (EC).
5.4.1
Emergency Medical Contacts
24 HOUR MEDICAL COVERAGE (Roche Emergency Medical Call Center Help 
Desk):  Within the United States, on weekends, holidays, and after 5:00 pm, call: 
1-866-286-9573 and ask for the physician on call.  From Australia, call 1-800-031-902 
and ask for the physician on call. (Note:  the number for Australia cannot be dialed from 
a mobile phone.)
To ensure the safety of study patients, an Emergency Medical Call Center Help Desk will 
access the Roche Medical Emergency List, escalate emergency medical calls, provide 
medical translation service (if necessary), connect the investigator with a Roche Medical 
Monitor, and track all calls.  The Emergency Medical Call Center Help Desk will be 
available 24 hours per day, 7 days per week.  Toll-free numbers for the Help Desk and 
Medical Monitor contact information will be distributed to all investigators (see "Protocol 
Administrative and Contact Information & List of Investigators"). 
5.4.2
Reporting Requirements for Serious Adverse Events and 
Non-Serious Adverse Events of Special Interest
For reports of serious adverse events and non-serious adverse events of special interest, 
investigators should record all case details that can be gathered within 24 hours on the 
Adverse Event eCRF and submit the report via the electronic data capture (EDC) system.  


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
63
A report will be generated and sent to Roche Safety Risk Management by the EDC 
system.
In the event that the EDC system is unavailable, a paper Serious Adverse 
Event/Non-Serious Adverse Event of Special Interest CRF and Fax Coversheet should 
be completed and faxed to Roche Safety Risk Management or its designee within 
24 hours after learning of the event with use of the fax numbers provided to investigators 
(see "Protocol Administrative and Contact Information & List of Investigators").  Once the 
EDC system is available, all information will need to be entered and submitted via the 
EDC system.  
5.4.3
Reporting Requirements for Pregnancies
5.4.3.1
Pregnancies in Female Patients
Female patients of childbearing potential will be instructed to immediately inform the 
investigator if they become pregnant during the study or within 6 months after the last 
doses of study drug.  A Pregnancy Report eCRF should be completed by the 
investigator within 24 hours after learning of the pregnancy and submitted via the EDC 
system.  A pregnancy report will automatically be generated and sent to Roche Safety 
Risk Management.  Pregnancy should not be recorded on the Adverse Event eCRF.  
The investigator should discontinue vemurafenib and counsel the patient, discussing the 
risks of the pregnancy and the possible effects on the fetus.  Monitoring of the patient 
should continue until conclusion of the pregnancy.
In the event that the EDC system is unavailable, a Pregnancy Report worksheet and 
Pregnancy Fax Coversheet should be completed and faxed to Roche Safety Risk 
Management or its designee within 24 hours after learning of the pregnancy with use of
the fax numbers provided to investigators (see "Protocol Administrative and Contact 
Information & List of Investigators").
5.4.3.2
Pregnancies in Female Partners of Male Patients
Male patients will be instructed through the Informed Consent Form to immediately 
inform the investigator if their partner becomes pregnant during the study or within 
6 months after the last dose of vemurafenib.  A Pregnancy Report eCRF should be 
completed by the investigator within 24 hours after learning of the pregnancy and 
submitted via the EDC system.  Attempts should be made to collect and report details of 
the course and outcome of any pregnancy in the partner of a male patient exposed to 
study drug.  When permitted by the site, pregnant partner would need to sign an
Authorization for Use and Disclosure of Pregnancy Health Information to allow for 
follow-up on her pregnancy.  If the authorization has been signed, the investigator 
should update the Pregnancy Report eCRF with additional information on the course 
and outcome of the pregnancy.  An investigator who is contacted by the male patient or 
his pregnant partner may provide information on the risks of the pregnancy and the 
possible effects on the fetus, to support an informed decision in cooperation with the 
treating physician and/or obstetrician.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
64
In the event that the EDC system is unavailable, reporting instructions provided in 
Section 5.4.3.1 should be followed.
5.4.3.3
Abortions
Any spontaneous abortion should be classified as a serious adverse event (because the 
Sponsor considers spontaneous abortions to be medically significant events), recorded 
on the Adverse Event eCRF, and reported to the Sponsor within 24 hours after learning 
of the event (see Section 5.4.2).  
5.4.3.4
Congenital Anomalies or Birth Defects
Any congenital anomaly or birth defect in a child born to a female patient (or female 
partner of a male patient exposed to vemurafenib) should be classified as a serious 
adverse event, recorded on the Adverse Event eCRF, and reported to the Sponsor 
within 24 hours after learning of the event (see Section 5.4.2).
5.5
FOLLOW-UP OF PATIENTS AFTER ADVERSE EVENTS
5.5.1
Investigator Follow-Up
The investigator should follow each adverse event until the event has resolved to 
baseline grade or better, the event is assessed as stable by the investigator, the patient 
is lost to follow-up, or the patient withdraws consent.  Every effort should be made to 
follow all serious adverse events considered to be related to study drug or trial-related 
procedures until a final outcome can be reported.
During the study period, resolution of adverse events (with dates) should be documented 
on the Adverse Event eCRF and in the patient’s medical record to facilitate source data 
verification.  
All pregnancies reported during the study should be followed until pregnancy outcome.  
5.5.2
Sponsor Follow-Up
For serious adverse events, non-serious adverse event of special interest, and 
pregnancies, the Sponsor or a designee may follow up by telephone, fax, electronic mail, 
and/or a monitoring visit to obtain additional case details and outcome information 
(e.g., from hospital discharge summaries, consultant reports, autopsy reports) in order to 
perform an independent medical assessment of the reported case.
5.6
ADVERSE EVENTS THAT OCCUR AFTER THE ADVERSE 
EVENT REPORTING PERIOD
The Sponsor should be notified if the investigator becomes aware of any serious adverse 
event that occurs after the end of the adverse event reporting period (defined as 28 days 
[see Section 5.3.1] after the final dose of study drug), if the event is believed to be 
related to prior study drug treatment.  These events should be reported through use of 
the Adverse Event eCRF.  However, if the EDC system is not available, the investigator 
should report these events directly to the Sponsor or its designee, either by faxing or by 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
65
scanning and emailing the paper Clinical Trial Serious Adverse Event/Adverse Event 
of Special Interest Reporting Form using the fax number or email address provided to 
investigators.
5.7
EXPEDITED REPORTING TO HEALTH AUTHORITIES, 
INVESTIGATORS, INSTITUTIONAL REVIEW BOARDS, AND 
ETHICS COMMITTEES
To determine reporting requirements for single adverse event cases, the Sponsor will 
assess the expectedness of these events using the following reference document(s):

Vemurafenib IB

Local prescribing information for Zelboraf(vemurafenib)

Vemurafenib (Zelboraf) Core Data Sheet
The Sponsor will compare the severity of each event and the cumulative event 
frequency reported for the study with the severity and frequency reported in the 
applicable reference document.
Reporting requirements will also be based on the investigator's assessment of causality 
and seriousness, with allowance for upgrading by the Sponsor as needed.
6.
STATISTICAL CONSIDERATIONS AND ANALYSIS PLAN
There is no formal hypothesis testing in this extension (rollover) study.  Data will be 
collected and reported descriptively for all study endpoints.  
The final analysis of this study will be performed when all patients have been followed up 
per protocol (see Section 3.2 and Section 3.3).
6.1
SUMMARIES OF CONDUCT OF STUDY
A clinical study report will be written and distributed to Health Authorities as required by 
applicable regulatory requirements.  Enrollment, eligibility violations, and study treatment 
administration will be summarized.  Patient disposition will be summarized and include 
whether treatment was completed or discontinued early and the reason for early 
treatment discontinuation.  
6.2
EFFICACY ANALYSIS
No protocol-specific efficacy analysis will be performed for this study. 
6.3
SAFETY ANALYSIS
The safety analysis will include all patients who receive at least one dose of vemurafenib.
Incidence, nature, and intensity (severity) of adverse events and serious adverse events, 
graded according to NCI CTCAE v4.0 will be summarized.


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5

Changes in vital signs (blood pressure, pulse, temperature), ECGs, and clinical 
laboratory results during the course of study will be summarized.
7.
DATA COLLECTION AND MANAGEMENT
7.1
DATA QUALITY ASSURANCE
Roche will be responsible for data management of this study, including quality checking 
of the data.  Data entered manually will be collected via EDC with use of eCRFs.  Sites 
will be responsible for data entry into the EDC system.  In the event of discrepant data, 
Roche will request data clarification from the sites, which the sites will resolve 
electronically in the EDC system.
Roche will produce an EDC Study Specification document that describes the quality 
checking to be performed on the data.  Central laboratory data will be sent directly to 
Roche, with use of Roche’s standard procedures to handle and process the electronic 
transfer of these data.
eCRFs and correction documentation will be maintained in the EDC system’s audit trail.  
System backups for data stored at Roche and records retention for the study data will be 
consistent with Roche’s standard procedures.
7.2
ELECTRONIC CASE REPORT FORMS 
eCRFs are to be completed using a Sponsor-designated EDC system.  Sites will receive 
training and have access to a manual for appropriate eCRF completion.  eCRFs will be 
submitted electronically to Roche and should be handled in accordance with instructions 
from Roche.
All eCRFs should be completed by designated, trained site staff.  eCRFs should be 
reviewed and electronically signed and dated by the investigator or a designee.
At the end of the study, the investigator will receive patient data for his or her site in a 
readable format on a compact disc that must be kept with the study records.  
Acknowledgement of receipt of the compact disc is required.
7.3
SOURCE DATA DOCUMENTATION
Study monitors will perform ongoing source data verification to confirm that critical 
protocol data (i.e., source data) entered into the eCRFs by authorized site personnel are 
accurate, complete, and verifiable from source documents. 
Source documents (paper or electronic) are those in which patient data are recorded 
and documented for the first time.  They include but are not limited to hospital records, 
clinical and office charts, laboratory notes, memoranda, patient-reported outcomes, 
evaluation checklists, pharmacy dispensing records, recorded data from automated 
instruments, copies of transcriptions that are certified after verification as being accurate 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
67
and complete, microfiche, photographic negatives, microfilm or magnetic media, X-rays, 
patient files, and records kept at pharmacies, laboratories, and medico-technical 
departments involved in a clinical trial.
Before study initiation, the types of source documents that are to be generated will be 
clearly defined in the Trial Monitoring Plan.  This includes any protocol data to be 
entered directly into the eCRFs (i.e., no prior written or electronic record of the data) and 
considered source data.
Source documents that are required to verify the validity and completeness of data 
entered into the eCRFs must not be obliterated or destroyed and must be retained per 
the policy for retention of records described in Section 7.5.
To facilitate source data verification, the investigators and institutions must provide the 
Sponsor direct access to applicable source documents and reports for trial-related 
monitoring, Sponsor audits, and IRB/EC review.  The investigational site must also allow 
inspection by applicable health authorities.
7.4
USE OF COMPUTERIZED SYSTEMS
When clinical observations are entered directly into an investigational site’s 
computerized medical record system (i.e., in lieu of original hardcopy records), the 
electronic record can serve as the source document if the system has been validated in 
accordance with health authority requirements pertaining to computerized systems used 
in clinical research.  An acceptable computerized data collection system allows 
preservation of the original entry of data.  If original data are modified, the system should 
maintain a viewable audit trail that shows the original data as well as the reason for the 
change, name of the person making the change, and date of the change.
7.5
RETENTION OF RECORDS
Records and documents pertaining to the conduct of this study and the distribution of 
IMP, including eCRFs, ePRO data (if applicable), Informed Consent Forms, laboratory 
test results, and medication inventory records, must be retained by the Principal 
Investigator for at least 15 years after completion or discontinuation of the study or for 
the length of time required by relevant national or local health authorities, whichever is 
longer.  After that period of time, the documents may be destroyed, subject to local 
regulations.  
No records may be disposed of without the written approval of Roche.  Written 
notification should be provided to Roche prior to transferring any records to another 
party or moving them to another location.

applicable local, state, and federal laws.  Studies conducted in the European 
Union/European Economic Area will comply with the E.U. Clinical Trial Directive 
(2001/20/EC).
8.2
INFORMED CONSENT
Roche’s sample Informed Consent Form (and ancillary sample Informed Consent Forms 
such as a Child’s Assent or Caregiver's Informed Consent Form, if applicable) will be 
provided to each site.  If applicable, it will be provided in a certified translation of the 
local language.  Roche or its designee must review and approve any proposed 
deviations from Roche's sample Informed Consent Forms or any alternate consent forms 
proposed by the site (collectively, the “Consent Forms”) before IRB/EC submission.  The 
final IRB/EC-approved Consent Forms must be provided to Roche for health authority 
submission purposes according to local requirements.
The Consent Forms must be signed and dated by the patient or the patient’s legally 
authorized representative before his or her participation in the study.  The case history or 
clinical records for each patient shall document the informed consent process and that 
written informed consent was obtained prior to participation in the study.
The Consent Forms should be revised whenever there are changes to study procedures 
or when new information becomes available that may affect the willingness of the patient 
to participate.  The final revised IRB/EC-approved Consent Forms must be provided to 
Roche for health authority submission purposes.
Patients must be re-consented to the most current version of the Consent Forms (or to a 
significant new information/findings addendum in accordance with applicable laws and 
IRB/EC policy) during their participation in the study.  For any updated or revised 
Consent Forms, the case history or clinical records for each patient shall document the 
informed consent process and that written informed consent was obtained using the 
updated/revised Consent Forms for continued participation in the study.
A copy of each signed Consent Form must be provided to the patient or the patient’s 
legally authorized representative.  All signed and dated Consent Forms must remain in 


Vemurafenib—F. Hoffmann-La Roche Ltd
Protocol GO28399, Version 5
69
each patient’s study file or in the site file and must be available for verification by study 
monitors at any time.
For sites in the United States, each Consent Form may also include patient authorization 
to allow use and disclosure of personal health information in compliance with the U.S. 
Health Insurance Portability and Accountability Act of 1996 (HIPAA).  If the site utilizes a 
separate Authorization Form for patient authorization for use and disclosure of personal 
health information under the HIPAA regulations, the review, approval, and other 
processes outlined above apply except that IRB review and approval may not be 
required per study site policies.
8.3
INSTITUTIONAL REVIEW BOARD OR ETHICS COMMITTEE
This protocol, the Informed Consent Forms, any information to be given to the patient, 
and relevant supporting information must be submitted to the IRB/EC by the Principal 
Investigator and reviewed and approved by the IRB/EC before the study is initiated.  
In addition, any patient recruitment materials must be approved by the IRB/EC. 
The Principal Investigator is responsible for providing written summaries of the status of 
the study to the IRB/EC annually or more frequently in accordance with the requirements, 
policies, and procedures established by the IRB/EC.  Investigators are also responsible 
for promptly informing the IRB/EC of any protocol amendments (see Section 9.5).
In addition to the requirements for reporting all adverse events to the Sponsor, 
investigators must comply with requirements for reporting serious adverse events to the 
local health authority and IRB/EC.  Investigators may receive written IND safety reports 
or other safety-related communications from Roche.  Investigators are responsible for 
ensuring that such reports are reviewed and processed in accordance with health 
authority requirements and the policies and procedures established by their IRB/EC and 
archived in the site’s study file.
8.4
CONFIDENTIALITY
Roche maintains confidentiality standards by coding each patient enrolled in the study 
through assignment of a unique patient identification number.  This means that patient 
names are not included in data sets that are transmitted to any Roche location.
Patient medical information obtained by this study is confidential and may only be 
disclosed to third parties as permitted by the Informed Consent Form (or separate 
authorization for use and disclosure of personal health information) signed by the patient, 
unless permitted or required by law.
Medical information may be given to a patient’s personal physician or other appropriate 
medical personnel responsible for the patient’s welfare, for treatment purposes.

9.4
PUBLICATION OF DATA AND PROTECTION OF TRADE 
SECRETS
The results of this study may be published or presented at scientific meetings.  If this is 
foreseen, the investigator agrees to submit all manuscripts or abstracts to Roche prior to
submission.  This allows the Sponsor to protect proprietary information and to provide 
comments based on information from other studies that may not yet be available to the 
investigator.
Roche will comply with the requirements for publication of study results.  In accordance 
with standard editorial and ethical practice, Roche will generally support publication of 
multicenter trials only in their entirety and not as individual center data.  In this case, a 
coordinating investigator will be designated by mutual agreement.
Authorship will be determined by mutual agreement and in line with International 
Committee of Medical Journal Editors authorship requirements.  Any formal publication 
of the study in which contribution of Roche personnel exceeded that of conventional 
monitoring will be considered as a joint publication by the investigator and the 
appropriate Roche personnel.

Notes:
Cycle length28 days; study visits will occur on Day 1 (3 days, unless otherwise specified) of each cycle through Cycle 7, and then on 
every other cycle (Cycles 9, 11, 13, 15).  Then, for patients still receiving treatment, clinic visits will occur on Day 1 of every third cycle 
(i.e., Cycles 18, 21, 24, etc.) until unacceptable toxicity or disease progression, as defined by the investigator.  Patients who have received a 
minimum of 17 cycles of vemurafenib treatment in the antecedent study will undergo the screening/baseline visit and then move directly to 
every-third-cycle study visits commencing with the Cycle 18 visit. Visits are to be scheduled from screening/baseline visit.
On the day of scheduled assessments, assessments should be performed prior to study drug dosing, unless otherwise specified.
All required screening/baseline procedures including data collection/transfer from the antecedent study need to be performed after the patient 
provides inform consent within a maximum window of 15 days from the last day of the antecedent study until treatment start in the extension 
(rollover) study, except where otherwise indicated.

a.
Results from the study completion visit or other prior visit assessment in the antecedent protocol may be used as screening/baseline for 
this extension (rollover) study, if within the time intervals, as specified below.
b.
Complete physical examination will include the measurement of patients’ weight and height, as well as an evaluation of the head, eye, ear,
nose, and throat and the cardiovascular, dermatological, musculoskeletal, respiratory, gastrointestinal, genitourinary, and neurological 
systems at baseline and end of treatment visit. 
Results from antecedent study can be used for baseline/screening assessment if it was performed within 30 days before treatment on 
Study GO28399.
At subsequent visits, limited, symptom-directed physical examinations, and, minimally, examination of the eye and the cardiovascular and 
dermatological systems should be performed.
c.
Visual and digital evaluation of the anus and anal canal will be performed at baseline (unless previously done in the antecedent protocol) 
and at the end of treatment visit.  In addition, all female patients will undergo a pelvic examination including visual inspection of the uterine 
cervix and Papanicolaou smear at baseline (unless previously performed in the antecedent protocol) and at the end of treatment visit.  
An examination from the antecedent protocol may be utilized as the screening examination for the extension (rollover) protocol if it was 
conducted during the screening period or the conduct of the antecedent protocol.
d.
Hematology (hemoglobin, hematocrit, WBC count with differential [neutrophils, bands, eosinophils, basophils, lymphocytes, monocytes], 
and platelet count may be obtained up to 4 days prior to the scheduled clinic visit (as applicable) for Day 1 of each treatment cycle.  
An examination from the antecedent protocol may be utilized as the screening examination for the extension (rollover) protocol if it was 
conducted within 15 days prior to first dose of vemurafenib on Study GO28399.
e.
Serum chemistry (sodium, potassium, chloride, bicarbonate, BUN, creatinine, calcium, phosphate, magnesium, total and direct bilirubin, 
albumin, AST, ALT, LDH, and ALP) may be obtained up to 4 days prior to the scheduled clinic visit (as applicable) for Day 1 of each 
treatment cycle.  An examination from the antecedent protocol may be utilized as the screening examination for the extension (rollover) 
protocol, if it was conducted within 15 days prior to first dose of vemurafenib.
f.
ECG assessments will be taken every cycle through Cycle 3, followed by every other cycle through Cycle 15 and every third cycle starting 
at Cycle 18 and at the end of treatment visit.  All ECGs will be taken at least 15 minutes before any type of blood draw.  ECG assessments 
may be obtained up to 4 days prior to the scheduled clinic visit (as applicable) for Day 1 of each treatment cycle.  An examination from the 
antecedent protocol may be utilized as the screening examination for the extension (rollover) protocol if it was conducted within 14 days
prior to first dose of vemurafenib on Study GO28399.

g.
A thorough head and neck examination to monitor for non-cutaneous SCC, consisting of at least a visual inspection of the oral mucosa 
and lymph node palpation, must be performed by the treating physician or other qualified physician at screening for all patients enrolled.  
The screening examination from the antecedent protocol may be utilized as the screening examination for the extension (rollover) protocol 
if it was conducted within 30 days prior to first dose of vemurafenib on Study GO28399.  Thereafter, the head and neck examination will be 
repeated by the treating physician or other qualified physician every other treatment cycle after initiation of study treatment and every other 
cycle through Cycle 15.  Then, for patients still receiving treatment, the head and neck examination will continue to be conducted every 
third treatment cycle starting at Cycle 18 (i.e., screening and every three cycles per the Cycle 18period for patients with 17 cycles of 
vemurafenib on an antecedent study), and until withdrawal of consent, death, or loss to follow-up (whichever occurs earliest).  A window of 
21 days from the scheduled study visit (with exception of the baseline evaluation) is allowed for completion of the assessment.  
h.
Any identified lesion suspected to be a new primary malignancy (including cuSCC, non-cutaneous SCC, and/or new primary melanoma) 
must be biopsied or excised and sent for pathological examination and should be treated according local institutional standard of care.  
i.
A dermatological evaluation will be conducted at baseline, prior to treatment, at Cycles 2 and 3, then every other cycle through Cycle 15.  
Then, for patients still receiving treatment, a dermatological evaluation will continue to be conducted every third treatment cycle starting at 
Cycle 18 (i.e., screening and every three cycles per the Cycle 18period for patients with 17 cycles of vemurafenib on an antecedent 
study), and until withdrawal of consent, death, or loss to follow-up (whichever occurs earliest).  A window of 21 days from the scheduled 
study visit (with exception of the baseline evaluation) is allowed for completion of the dermatologic assessments cited above.  It is 
recommended that the examination to be performed by a dermatologist; however, it can also be performed by a qualified physician.  All 
patients will be followed for cuSCC, as well as other new cutaneous neoplasms, until 28 days after treatment completion, death, withdrawal 
of consent, or loss to follow-up, whichever occurs first.  Patients should see their physicians as needed for any new skin lesions while on 
the study drug.  An unscheduled dermatology examination may be performed at any time during treatment, if clinically indicated.  An 
examination from the antecedent protocol may be utilized as the screening examination for the extension (rollover) protocol if it was 
conducted within 30 days prior to first dose of vemurafenib on Study GO28399.
j.
Chest CT scans must be performed at baseline, within 30 days before start of study treatment on Study GO28399, and every 6 months 
(within a window of 21 days) after initiation of treatment until death, withdrawal of consent, loss to follow up or up to 28 days after study 
drug discontinuation, whichever occurs first.  Available routine chest CT scans (e.g., performed for tumor assessments during the 
antecedent study period) that fit the required timeline specification can be used for this safety surveillance. 
k.
Tumor assessments, including radiological tumor assessments of chest, abdomen, pelvis, and brain, for measuring extent of disease 
(CT scan is the preferred method) will be done at the discretion of the investigator or per institutional guidelines.  An examination from the 
antecedent protocol may be utilized as the screening examination for the extension (rollover) protocol if it was conducted within 30 days
prior to the first dose of vemurafenib.

study if the sample is available by routine biopsy.
m.
A serum pregnancy test for women of childbearing potential, including premenopausal women who have had a tubal ligation, must be 
collected at baseline within 7 days preceding the planned first dose of treatment on Study GO28399.
n.
Urine pregnancy test prior to each treatment cycle for women of childbearing potential, including premenopausal women who have had a 
tubal ligation, may be obtained up to 4 days prior to the scheduled clinic visit (as applicable) for Day 1 of each treatment cycle.  If positive, 
a serum pregnancy test should be performed.
Additional physical examination, clinical, laboratory (e.g., hematology, chemistry, ECG, etc.) and other diagnostic studies may be conducted at 
scheduled and non-scheduled timepoints to evaluate safety and to assess tumor status, as may be clinically indicated, at the discretion of the

Appendix 5 ICH Guidelines for Clinical Safety Data Management, 
Definitions and Standards for Expedited Reporting, Topic E2
A serious adverse event is any experience that suggests a significant hazard, 
contraindication, side effect or precaution.  It is any adverse event that at any dose fulfills 
at least one of the following criteria:

Is fatal (results in death) (Note:  Death is an outcome, not an event.)

Is life threatening (Note:  The term "life threatening" refers to an event in which the 
patient was at immediate risk of death at the time of the event; it does not refer to an 
event that could hypothetically have caused a death had it been more severe.)

Required in-patient hospitalization or prolongation of existing hospitalization

Results in persistent or significant disability/incapacity

Is a congenital anomaly/birth defect

Is medically significant or requires intervention to prevent one or other of the 
outcomes listed above
Medical and scientific judgment should be exercised in deciding whether expedited 
reporting to the Sponsor is appropriate in other situations, such as important medical 
events that may not be immediately life threatening or result in death or hospitalization 
but may jeopardize the patient or may require intervention to prevent one of the 
outcomes listed in the definitions above.  These situations should also usually be 
considered serious.
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm; blood dyscrasias, or convulsions that do not result in 
hospitalization or development of drug dependency or drug abuse.
An unexpected adverse event is an adverse reaction, the nature or severity of which is not 
consistent with the applicable product information.
The investigator initially assesses causality.  For serious adverse events, selecting one 
or more options indicates possible causes of the event.  (Check all that apply.) 

Preexisting/underlying diseasespecify 

Study treatmentspecify the drug(s) related to the event

Other treatment (concomitant or previous)specify

Protocol-related procedure

Other (e.g., accident, new or intercurrent illness)specify
The term severe is a measure of intensity; thus, a severe adverse event is not 
necessarily serious.  For example, nausea of several hours of duration may be rated as 
severe but may not be clinically serious.

A serious adverse event occurring during the study or that comes to the attention of the 
investigator within 15 days after stopping the treatment or during the protocol-defined 
follow-up period, if this is longerwhether considered treatment-related or notmust be 
reported.  In addition, a serious adverse event that occurs after this time, if considered 
related to test drug, should be reported.
Such preliminary reports will be followed by detailed descriptions later that will include 
copies of hospital case reports, autopsy reports, and other documents when requested 
and applicable.
For serious adverse events, the following must be assessed and recorded on the 
adverse events page of the electronic Case Report Form: intensity, relationship to test 
substance, action taken, and outcome to date.
The investigator must notify the Ethics Review Committee/Institutional Review Board of 
a serious adverse event in writing as soon as is practical and in accordance with 
international and local laws and regulations.
