Protocol Synopsis 
Title:  A Phase 2, Multicenter, Open-label, Single-arm Trial to Evaluate the Correlation Between 
Objective Response Rate and Baseline Intratumoral CD8+ Cell Density in Subjects With 
Unresected Stage IIIB to IVM1c Melanoma Treated with Talimogene Laherparepvec 
Study Phase:  2 
Indication:  Unresected stage IIIB to IVM1c melanoma 
Primary Objective:  The primary objective is to explore the correlation between baseline 
intratumoral CD8+ cell density and objective response rate (ORR) in subjects with unresected 
stage IIIB to IVM1c melanoma treated with talimogene laherparepvec. 
Secondary Objective(s):   
• 
to explore the correlation between baseline intratumoral CD8+ cell density and durable 
response rate (DRR), duration of response (DOR), and changes in tumor burden 
• 
to explore the correlation between changes in intratumoral CD8+ cell density during treatment 
and ORR, DRR, DOR, and changes in tumor burden 
• 
to evaluate ORR, DOR, time to treatment failure (TTF), DRR, OS, and change in tumor 
burden during treatment 
• 
to evaluate the safety and tolerability of talimogene laherparepvec  
Exploratory Objective(s):   
• 
to investigate the correlation between the changes in the population of tumor specific 
cytotoxic T cells and immunoscore during treatment and clinical response 
• 
to identify other potential blood and tissue biomarkers which correlate with or predict clinical 
outcome to talimogene laherparepvec 
Hypotheses:   
No formal statistical hypothesis will be tested in this trial.  The study will explore the hypothesis 
that intratumoral CD8+ cell density at baseline correlates with objective response rate in subjects 
with unresected stage IIIB to IVMIc melanoma treated with talimogene laherparepvec. 
Primary Endpoint:   
Correlation between baseline intratumoral CD8+ cell density and objective response rate 
Secondary Endpoint(s):  
• 
correlation between baseline intratumoral CD8+ cell density and DRR, DOR, and changes in 
tumor burden  
• 
correlation between changes in intratumoral CD8+ cell density during treatment and ORR, 
DRR, DOR, and changes in tumor burden  
• 
efficacy endpoints:  ORR, DOR, TTF,  DRR, OS, and change in tumor burden during 
treatment 
• 
safety endpoints:  subject incidence of treatment-emergent and treatment-related adverse 
events (including all adverse events, grade ≥ 3 adverse events, serious adverse events, fatal 
adverse events, events of interest, adverse events requiring the discontinuation of study 
drug), clinically significant laboratory changes, and incidence of symptomatic herpetic lesions 
that are positive for talimogene laherparepvec 
Exploratory Endpoint(s): 
•

Study Design:   
This is a phase 2, multicenter, open-label, single-arm study to evaluate biomarkers in subjects 
with unresected stage IIIB to IVM1c melanoma who are treated with talimogene laherparepvec.  
Subjects will be treated with talimogene laherparepvec until the subject has achieved a complete 
response, all injectable tumors have disappeared, clinically significant (resulting in clinical 
deterioration or requiring change of therapy) disease progression beyond 6 months of treatment, 
per modified World Health Organization (WHO) response criteria (WHO handbook for reporting 
results of cancer treatment, 1979; refer to Appendix D), or intolerance of study treatment, 
whichever occurs first.   
Subjects will be followed for safety 30 (+ 7) days after the last dose of talimogene laherparepvec 
and for survival every 12 weeks (± 28 days) for up to approximately 24 months after the last 
subject is enrolled in the study.  Thereafter, subjects will be followed under an ongoing separate 
registry protocol (Study 20120139) for the long-term survival follow-up of subjects treated with 
talimogene laherparepvec.  The registry protocol will also monitor for late and long-term adverse 
events thought to be potentially related to talimogene laherparepvec and use of anti-cancer 
therapy for melanoma. 
Blood and tumor tissue samples will be collected at timepoints outlined in the Schedule of 
Assessments (Table 2).  Tumor biopsies (taken from accessible cutaneous, subcutaneous or 
nodal lesions) will be performed on an uninjected lesion on day 1 of week 1, on a different 
uninjected lesion at week 6 (if available), and at disease progression that results in treatment 
discontinuation from the lesion responsible for progression as outlined in Section 7.2.2.  
Samples will be analyzed to explore if intratumoral CD8+ cell density at baseline and its change 
during treatment is correlated with the objective response rate in subjects with unresected stage 
IIIB-IVM1c melanoma treated with talimogene laherparepvec.   
For a full description of the study design, please refer to Section 3.1. 
Sample Size:  Approximately 110 subjects will be enrolled in the study.

For a full list of study procedures, including the timing of each procedure, please refer to 
Section 7 and the Schedule of Assessments (Table 2).   
Statistical Considerations:   
All analyses will be descriptive with no formal hypothesis testing.  The primary objective of the 
study is to explore the correlation between baseline intratumoral CD8+ cell density and objective 
response rate (ORR).  The sample size was selected based on practical considerations.  The 
adequacy of the sample size is discussed in Section 10.2.  
The main goals of the primary analysis are to evaluate the correlation between baseline 
intratumoral CD8+ cell density and ORR,DRR,DOR, and changes in tumor burden, in addition to 
the correlation between changes in intratumoral CD8+ cell density during treatment and 
ORR,DRR,DOR, and changes in tumor burden.  The timing of the primary analysis will be when 
all subjects have had the opportunity to complete 12 months of treatment with talimogene 
laherparepvec. 
An interim analysis to evaluate the study objectives will be conducted on approximately 
the first 50 subjects who received at least 1 dose of talimogene laherparepvec, with the 
biomarker recorded at baseline, and have had the opportunity to be in the study (treatment 
or follow-up) for 6 months.   
The final analysis will occur either 24 months after the last subject has been enrolled or when 
the last subject discontinues the study treatment and has had the opportunity to complete the 
safety follow-up, whichever is later.   
Descriptive statistics will be provided for demographic, safety, efficacy, and biomarkers as 
appropriate.  In general, the safety analysis set will be used for all safety analyses.  The safety 
analyses include incidence of treatment-emergent and treatment-related adverse events 
(all adverse events, ≥ grade 3 adverse events, serious adverse events, fatal adverse events and 
adverse events defined as events of interest). 
The efficacy analysis will be conducted using the safety analysis set as well, unless otherwise 
specified.  The ORR will be estimated with the associated 95% CI.  Descriptive statistics for DRR, 
time to treatment failure, changes in tumor burden, and OS will be provided.  In addition, DOR 
and changes in tumor burden for responders will also be summarized. 
The correlation between a baseline biomarker and response rate will be evaluated.  The 
functional manner in which the response rate may vary with the biomarker is unknown; therefore 
multiple functional relationships may be examined.  Pearson’s correlation coefficient (r) will be 
estimated between the biomarker change and the maximum decrease in index lesions to 
evaluate the correlation between changes in a biomarker post-treatment and the effect of 
treatment on measurable lesions, in addition to correlating biomarker changes with objective 
response using logistic regression. 
For further details on the statistical analysis, please refer to Section 10.

The primary objective is to explore the correlation between baseline intratumoral 
CD8+ cell density and objective response rate (ORR) in subjects with unresected stage 
IIIB to IVM1c melanoma treated with talimogene laherparepvec. 
1.2 
Secondary 
The secondary objectives are as follows: 
• 
to explore the correlation between baseline intratumoral CD8+ cell density and 
durable response rate (DRR), duration of response (DOR), and changes in tumor 
burden 
• 
to explore the correlation between changes in intratumoral CD8+ cell density during 
treatment and ORR, DRR, DOR, and changes in tumor burden 
•

BACKGROUND AND RATIONALE 
2.1 
Melanoma 
Cutaneous melanoma is the fifth most common cancer in men and the seventh most 
common cancer in women in the United States of America (USA), with an estimated 
73,870 new cases and 9,940 deaths expected in 2015 (Siegel et al, 2015).  In Europe, 
the annual incidence of melanoma is somewhat lower than that in the USA, with a crude 
rate of approximately 14 per 100,000 as compared to 20 per 100,000 in the USA, but is 
the sixth most common cancer among women (Ferlay et al, 2013; Siegel et al, 2014).  In 
Europe as a whole, approximately 100,442 new cases were diagnosed in 2012 
(Ferlay et al, 2013).  The incidence of melanoma is increasing rapidly worldwide, with a 
270% increase in the USA between 1973 and 2002.  This increase is the most rapid of 
any cancer with the exception of lung cancer in women (Jemal et al, 2006; 
Ries et al, 2000).

Melanoma that has spread to multiple regional nodal sites (stage III) is infrequently 
curable with standard therapy.  For those with multiple or clinically detectable nodal 
metastases or in-transit/satellite lesions (stages lllB and lllC), the 5-year survival rate 
ranges between 40% (for stage lllC disease) to 59% (for stage lllB disease) 
(Balch et al, 2009).  For patients with distant spread to skin, nodes, or visceral organs 
(stage IV disease), the 5-year survival rates are generally low, ranging from 20% for 
stage M1a disease (skin, subcutaneous or nodes only), 5% to 10% for stage M1b 
disease (lung only), and < 5% for stage M1c disease (other visceral lesions or high 
serum lactate dehydrogenase [LDH]); median survival is 12 months for stages M1a and 
M1b disease and 4 to 6 months for stage M1c disease (O'Day and Boasberg, 2006; 
Tannous et al, 2005). 
Until recently, traditional nonsurgical therapies for unresectable or advanced melanoma 
in adults included chemotherapy (dacarbazine, temozolomide, or other agents either 
alone or in combination), or interleukin-2.  Although some regimens produced objective 
responses, they were usually short-lived (Anderson et al, 1995; Chapman et al, 1999; 
Wagner et al, 2000; Middleton et al, 2000).  Response rates for interleukin-2 ranged 
from 10% to 20% (Rosenberg et al, 1994; Sparano et al, 1993; Atkins et al, 1999), with a 
small proportion achieving prolonged response, but its administration requires close 
patient monitoring in specialized facilities with well-trained staff based on the notable 
toxicity profile associated with its administration. 
Recently, the Food and Drug Administration (FDA), European Commission, and other 
regulatory agencies have approved 6 novel therapies for advanced melanoma:  an 
immune stimulatory agent, ipilimumab (Yervoy®, 2015), pembrolizumab (Keytruda®, 
2015) and nivolumab (Opdivo®, 2015) and 3 agents for use in patients with BRAF 
mutant melanoma, a v-raf murine sarcoma viral oncogene homolog B1 (BRAF) inhibitor, 
vemurafenib (Zelboraf®, 2015), the BRAF inhibitor dabrafenib (Tafinlar™, 2013) and the 
MEK inhibitor trametinib (Mekinist™, 2014).  The studies upon which approvals for 
ipilimumab and vemurafenib were based demonstrated improved survival compared to 
control treatments.  The pivotal study of ipilimumab showed an overall survival (OS) 
improvement in subjects with human leukocyte antigen (HLA)-A2*0201 genotype 
previously treated metastatic melanoma as compared with a gp100 peptide vaccine 
(Hodi et al, 2010; Yervoy 2015).  The median overall survival (OS) was 10.0 months in 
the group that received ipilimumab in combination with the gp100 peptide vaccine and 
6.4 months in the group that received gp100 peptide vaccine alone (hazard ratio

[HR] = 0.68, p < 0.001) (Hodi et al, 2010).  Approximately 8% more patients survived 
2 years in the ipilimumab arm than in the control arm (21.6% vs 13.7%).  The objective 
response rate was 5.7% vs 1.5%, respectively (p = 0.04).  Similar results were reported 
for another study conducted in previously untreated subjects with metastatic melanoma 
who received ipilimumab and dacarbazine vs placebo and dacarbazine 
(Robert et al, 2011).  
The pivotal vemurafenib study showed improved OS and objective response rates in a 
substantial proportion of subjects with previously untreated metastatic melanoma with 
the BRAFV600E mutation who received vemurafenib vs standard dacarbazine 
(Chapman et al, 2011).  The median OS was 13.6 months in the vemurafenib group and 
9.4 months in the dacarbazine group (OS data for dacarbazine patients who crossed 
over to vemurafenib treatment were censored at the time of crossover) 
(Chapman et al, 2012).  The hazard ratio for death was 0.62 (95% Confidence interval 
[Cl]:  0.49, 0.77).  The objective response rate was 48% vs 5%, respectively (p < 0.001) 
(Chapman et al, 2011).   
In 2013, regulatory agencies also approved the BRAF inhibitor dabrafenib 
(Tafinlar™, 2013) and the MEK  inhibitor trametinib (Mekinist™, 2014), both in BRAFV600 
mutant advanced melanoma.  Each agent showed a benefit in progression-free survival 
compared to dacarbazine in Phase 3 trials (Hauschild et al, 2012; Flaherty et al, 2012a).  
Additionally, dabrafenib and trametinib were approved recently as a combination therapy 
for BRAF-mutant (V600 E/K) unresectable or metastatic melanoma. (Flaherty et al, 
2012b; Long et al, 2015; Robert et al, 2015).  
Nivolumab, an anti-PD-1 monoclonal antibody, demonstrated improvement in 
1-year OS in treatment naïve subjects with wild-type BRAF advanced melanoma 
compared  to dacarbazine (73% versus 42%; HR 0.42, 99.8% CI 0.25-0.73) 
(Robert et al, 2015); improved ORR  in subjects  previously treated with either 
ipilimumab or BRAF inhibitor versus dacarbazine or carboplatin with paclitaxel 
(32% vs 10%) (Weber et al, 2015), and improved PFS and ORR (either alone or in 
combination with ipilimumab) compared to  ipilimumab alone in treatment naïve 
subjects (Larkin et al, 2015). 
Pembrolizumab, is a monoclonal antibody that targets PD-1 protein, improved PFS 
and OS versus ipilimumab in subjects with advanced melanoma. Six-month 
progression-free rates were 47% and 46%, for pembrolizumab administered every 
2 and 3 weeks, versus 27% for ipilimumab (HR 0.58; P<0.001 for both

Protocol Number:  20120325

pembrolizumab regimens versus ipilimumab). Twelve-months OS rates were 74%, 
68%, and 58%, respectively (HR 0.63, P=0.0005 for pembrolizumab every 2  weeks 
and 0.69, P=0.004 for pembrolizumab every  3 weeks) (Robert et al, 2015) 
While the approval of these newer agents represents a clear milestone in the treatment 
of advanced melanoma, limitations still exist.  The two-year overall survival following 
ipilimumab remains only approximately 20%, and the drug is associated with severe and 
potentially fatal immunological adverse effects (Hodi et al, 2010).  Although not as 
common and severe as with ipilimumab, a wide range of immune related toxicities 
has been reported with permbrolizumab and nivolumab, which include 
pneumonitis, hepatitis, colitis, nephritis, thyroid dysfunction and others 
(Larkin et al, 2015; Robert et al, 2015; Weber et al, 2015).  Vemurafenib, dabrafenib, 
and trametinib are indicated only in patients with BRAFV600 mutations, and are 
associated with early development of resistance in most cases, leading to short 
durations of response.  The safety profiles of vemurafenib and dabrafenib include 
increased incidence of cutaneous squamous cell carcinoma or high grade 
keratoacanthoma in almost 20% of patients treated with vemurafenib and > 5% of 
patients treated with dabrafenib (Zelboraf®, 2015; Tafinlar™, 2013).  Additionally, 
grade 2 or higher dermatologic reactions including rash, pruritus, and hyperkeratosis are 
common with both agents.  Trametinib is associated with cuneiform dermatitis, 
peripheral edema, hypertension, decreased cardiac ejection fraction, and ocular events 
(Mekinist™, 2014).  Thus, the need remains for additional treatment options for patients 
with advanced melanoma (including those with regional and/or distant metastases). 
Biomarkers of melanoma prognosis and treatment effect and toxicity have been 
increasingly well studied in the past few years.  BRAF mutations have been identified 
that predict for response to BRAF inhibitors (Hoeflich et al, 2009).  Immunologic-based 
biomarkers are likely to be important for immunotherapies, including talimogene 
laherparepvec.  Many tumors, including melanoma, are heavily infiltrated by 
inflammatory and lymphoid cells which can be used as prognostic and predictive 
biomarkers and a variety of “immunoscores” have been employed in attempts to capture 
the maximal prognostic value of intratumoral immune cells (Galon et al, 2012).  These 
immunoscores are generally algorithms that combine the number of one or more types 
of immune cells observed in the tumor with information on the localization of the immune 
cells within the tumor (eg, proximity to blood vessels, invasive margin).  The most 
commonly used immunoscore is based on the density of cytotoxic CD8+ T-lymphocytes 

Product:  Talimogene Laherparepvec 
Protocol Number:  20120325

in the center and in the invasive margins of tumor (Mlecnik et al, 2011).  The prognostic 
value of immunoscores composed of a combination of immunohistochemical staining 
densities for both intratumoral CD3+ / CD8+ T cells, combined with the location of the 
cells either in the invasive margin or central tumor, has been well documented in colon 
cancer and was shown to have a prognostic significance superior to that of the AJCC 
TNM classification system (Galon et al, 2006, Galon et al, 2012).  An international effort 
is underway to qualify an immunoscore as a predictive and prognostic biomarker for 
other cancers (Galon et al, 2014).   
Infiltrating T cells have also been shown to be prognostic for melanoma (Erdag et al, 
2012).  The authors’ primary analysis was performed using an immunoscore that 
counted CD45+ cells (lymphocytes) and combined the number of cells with the pattern of 
localization near blood vessels as detected by CD34+ staining.  They further showed 
that the single cell type most strongly correlated with survival was CD8+ cells which is 
why we have chosen to focus on CD8+ cells as the primary biomarker analysis in the 
current study.  Since talimogene laherparepvec is assumed to work via activation of 
tumor specific T cells, it is important to understand whether the number of infiltrating 
T cells at baseline impacts drug efficacy, especially since approximately one-third of 
melanomas have few or no infiltrating T cells (Erdag et al, 2012).  
The postulated dual mechanism of action of talimogene laherparepvec comprises a 
direct oncolytic effect achieved by infection and replication of the virus in tumor tissue 
resulting in tumor cell lysis and local release of tumor antigens, and enhancement of a 
systemic immune response by expression of GM-CSF in the tumor microenvironment to 
recruit and activate antigen presenting cells.  Activated antigen presenting cells initiate 
an adaptive antitumor immune response, ultimately leading to a persistent immunity.  In 
the current study we will measure tumor antigen-specific T cell responses induced by 
talimogene laherparepvec treatment in order to further explore mechanisms of action.   
Furthermore, baseline tumor mutational load and corresponding neoantigen 
signatures have been shown to correlate with responsiveness to immunotherapy 
(Rizvi et al, 2015; Snyder et al, 2014).  It will be important to understand if tumor 
mutational load can be predictive for response to talimogene laherparepvec as 
well. 
In addition, we will also explore the possibility that altered viral replication might affect 
response.  Deletion of the ICP34.5 gene is one of the means by which talimogene 
laherparepvec was engineered to limit replication to tumor cells.  ICP34.5 normally

interferes with the PKR (double-stranded RNA activated protein kinase) pathway which 
cells activate to protect themselves from viral infection.  This PKR pathway is typically 
inactivated in tumors, but the degree of residual PKR signaling in tumor cells may 
influence replication of talimogene laherparepvec.  Analysis of mutations in the PKR 
pathway and possibly other tumor cell pathways will be performed in this study in order 
to explore whether these mutations may affect response to treatment. 
2.2 
Talimogene Laherparepvec Investigational Product Background  
Talimogene laherparepvec is an intralesionally delivered oncolytic immunotherapy 
comprised of a genetically engineered HSV-1(herpes simplex virus type 1) that 
selectively replicates in tumor tissue (Talimogene Laherparepvec Investigator’s 
Brochure).  The neurovirulence factor ICP34.5 and the ICP47-encoding gene are 
functionally deleted in the virus, while the gene for human granulocyte macrophage 
colony-stimulating factor (GM-CSF) is inserted.  The role of ICP47 is to block antigen 
presentation to major histocompatibility complex class I molecules by blocking the 
transporter associated with antigen processing 1 and 2.  This deletion also allows the 
increased expression of the US11 gene.  This promotes virus growth in cancer cells 
without decreasing tumor selectivity. 
Additionally, the virus contains the coding sequence for human GM-CSF, a pleiotropic 
cytokine involved in the stimulation of cellular immune responses by promoting the 
generation of dendritic cells from blood monocytes (Demir et al, 2003; Lonial, 2004; 
Conti and Gessani, 2008).  Dendritic cells have the capacity to capture antigens, migrate 
in response to chemotactic stimuli, and induce proliferative responses and Th1 cytokine 
production in CD4+ and CD8+ T-lymphocytes (Hart, 1997; Steinman, 2001; Ikeda et al, 
2004; Paul, 2007).  These Th1-type cytokines have the capacity to produce 
proinflammatory responses, eradicate tumors, and perpetuate autoimmune responses 
(Nishimura et al, 2000; Ikeda et al, 2004; Knutson and Disis, 2005).   
Clinical data currently available has provided evidence of talimogene laherparepvec’s 
efficacy in patients with regionally and distantly metastatic melanoma (Talimogene 
Laherparepvec Investigator’s Brochure).  In particular, a high rate of complete response 
(CR) was achieved (16% in the phase 2 study with talimogene laherparepvec in stage 
lllC to IV melanoma) (Senzer et al, 2009; Talimogene Laherparepvec Investigator’s 
Brochure).  Moreover, responses were observed in both injected and uninjected sites, 
including visceral sites.  Responses were seen most often in earlier stage disease, 
including stage lllB/C and stage IVM1a, and in disease with lower visceral burden.

In the open-label, randomized, phase 3 study of talimogene laherparepvec versus 
subcutaneously administered GM-CSF in stages lllB, lllC, and IV unresectable 
melanoma, talimogene laherparepvec or GM-CSF was administered until CR, clinically 
significant disease progression, intolerable side effects, 12 months of therapy without an 
objective response, or withdrawal of consent (Study 20110263; OPTiM).  The primary 
endpoint of the study is durable response rate, defined as the rate of subjects with an 
objective response by central review (CR or partial response [PR]) lasting continuously 
for 6 months and starting any time within 12 months of initiating therapy. 
Primary analysis of the OPTiM Study showed a statistically significant difference 
between the rate of durable response among subjects treated with talimogene 
laherparepvec (16%; 95% CI:  12%, 21%) versus those treated with GM-CSF (2%; 95% 
CI:  0%, 5%) (p-value < 0.0001).  Overall response rate was also improved from 
6% with GM-CSF to 26% with talimogene laherparepvec (P < 0.0001, descriptive).  
Similarly, 11% of patients had a CR in the talimogene laherparepvec arm vs. 
< 1% in the GM-CSF arm.  In the event-driven primary OS analysis (secondary end 
point), median OS with talimogene laherparepvec treatment was 23.3 months 
compared with 18.9 months with GM-CSF treatment (HR, 0.79 [95% CI, 0.62‒1.00]; 
P = 0.051) (Andtbacka et al, 2015).  At the final planned analysis of OS which 
happened when last enrolled subject completed 3 years of follow-up, median OS 
was 23.3 months in the talimogene laherparepvec arm and 18.9 months in the 
GM-CSF arm (HR, 0.79; 95% CI, 0.62‒1.00; P=0.049), (descriptive) (Andtbacka et al, 
2015). 
The most common side effects were fatigue, chills, and pyrexia.  Serious adverse events 
occurred in 36% of the talimogene laherparepvec subjects and 21% of the GM-CSF 
subjects.  The only grade 3/4 adverse event occurring in ≥ 2% of patients was 
cellulitis (talimogene laherparepvec, n=6 [2.1%]; GM-CSF, n=1 [< 1%]).  Of 10 fatal 
events in the talimogene laherparepvec arm, none were considered 
treatment-related per investigator and most (80%) were associated with disease 
progression with the exception of sepsis in the setting of salmonella infection and 
myocardial infarction (Andtbacka et al, 2015).

laherparepvec.  Subjects with unresected stage IIIB to IVM1c melanoma who meet the 
eligibility criteria outlined in Section 4 will be considered for participation in this study.  
Talimogene laherparepvec will be administered by intralesional injection into injectable 
cutaneous, subcutaneous, and nodal tumors initially at a dose of 106 Plaque-Forming 
Unit (PFU)/mL at study day 1 followed by a dose of 108 PFU/mL 21 (+5 ) days after the 
initial dose and every 14 (± 3) days thereafter.  Subjects will be treated with talimogene 
laherparepvec until the subject has achieved a CR, all injectable tumors have 
disappeared, clinically significant (resulting in clinical deterioration or requiring change of 
therapy) disease progression beyond 6 months of treatment, per modified World Health 
Organization (WHO) response criteria (WHO handbook for reporting results of cancer 
treatment, 1979; refer to Appendix D), or intolerance of study treatment, whichever 
occurs first.  Due to the mechanism of action, subjects may experience transient growth 
of existing tumors or the appearance of new tumors prior to achieving maximal clinical 
benefit of talimogene laherparepvec.  Therefore, dosing should be continued for at least 
6 months from the time of initial dose regardless of progression provided that the subject 
is able to tolerate the treatment and does not develop deterioration of health status 
requiring other treatment. 
Subjects will be followed for safety 30 (+ 7) days after the last dose of talimogene 
laherparepvec for survival, adverse events thought by the investigator to be 
potentially related to talimogene laherparepvec, and use of anticancer therapies 
for melanoma every 12 weeks (± 28 days) for up to approximately 24 months after the 
last subject is enrolled  in the study.  Thereafter, subjects will be followed under an 
ongoing separate registry protocol (Study 20120139) for the long-term survival follow-up 
of subjects treated with talimogene laherparepvec.  The registry protocol will also 
monitor for late and long-term adverse events thought by the investigator to be 
potentially related to talimogene laherparepvec and use of anti-cancer therapies for 
melanoma. 
Blood and tumor tissue samples will be collected at timepoints outlined in the Schedule 
of Assessments (Table 2).  Tumor biopsies will be performed from an uninjected lesion 
on day 1 of week 1, from a different uninjected lesion at week 6 (if available), and from 
the lesion responsible for progression at the time of disease progression that 
results in treatment discontinuation as outlined in Section 7.2.2.  Samples will be 
analyzed to explore if intratumoral CD8+ cell density at baseline and its change during

treatment is correlated with the objective response rate in subjects with unresected 
stage IIIB-IVM1c melanoma treated with talimogene laherparepvec.   
The overall study design is described by a study schema at the end of the protocol 
synopsis section. 
The study endpoints are defined in Section 10.1.1. 
3.2 
Number of Sites 
Approximately 50 sites in Europe and the USA will participate in the study.  Additional 
sites and regions may be added to the study as necessary.  Sites that do not enroll 
subjects within 6 months of site initiation may be closed.   
3.3 
Number of Subjects 
Participants in this clinical investigation shall be referred to as “subjects”.  Approximately 
110 subjects will be enrolled in the study.  Refer to Section 10.2 for sample size 
considerations. 
3.4 
Replacement of Subjects 
Subjects who are withdrawn or removed from treatment or from the study will not be 
replaced. 
3.5 
Estimated Study Duration 
3.5.1 
Study Duration for Subjects 
The subject enrollment period is planned for approximately 17 months.   
The duration of the screening period for each subject will be up to 28 days.  The duration 
of treatment will vary for each subject.  Subjects will be treated with talimogene 
laherparepvec until the subject has achieved a CR, all injectable tumors have 
disappeared, clinically relevant (resulting in clinical deterioration or requiring change in 
therapy) disease progression beyond 6 months of treatment, per modified WHO 
response criteria (Appendix D), or intolerance of study treatment, whichever occurs first.  
Subjects will be followed for safety 30 (+ 7) days after the last dose of talimogene 
laherparepvec and for survival, adverse events thought by the investigator to be 
potentially related to talimogene laherparepvec, and use of anti-cancer therapy for 
melanoma every 12 weeks (± 28 days) for up to approximately 24 months after the last 
subject is enrolled in the study.  The estimated average per-subject study duration is 
approximately 32 months.

After the end of the long term follow up subjects who end the study for any reason 
other than death or withdrawal of full consent will continue to be followed for 
survival under an ongoing separate registry protocol (Study 20120139).  The 
registry protocol will also monitor for adverse events thought by the investigator 
to be potentially related to talimogene laherparepvec and use of anti-cancer 
therapies for melanoma. 
3.5.2 
End of Study 
Primary Completion:  the time when the last subject is assessed or receives an 
intervention for the purpose of final collection of data for the primary analysis.  The 
primary completion is anticipated to occur when all subjects have had the opportunity to 
complete 12 months of treatment. 
End of Trial:  the time when the last subject is assessed or receives an intervention for 
evaluation in the study.  The end of study will occur 24 months after the last subject 
has been enrolled or when the last subject discontinues talimogene laherparepvec and 
has had the opportunity to complete the safety follow-up visit, whichever occurs later.

SUBJECT ENROLLMENT 
Before subjects may be entered into the study, Amgen requires a copy of the site’s 
written institutional review board/independent ethics committee (IRB/IEC) approval of the 
protocol, informed consent form, and all other subject information and/or recruitment 
material, if applicable (see Section 11).  All subjects must personally sign and date the 
informed consent form before commencement of study-specific activities/procedures 
(ie, non-standard of care procedures).

CONFIDENTIAL 
 
 
All subjects who enter into the screening period for the study (defined as the point when 
the subject signs the informed consent) must be registered as screened subjects in the 
electronic trial operation (ETO) system and will receive a unique subject identification 
number before any study-specific procedures are performed.  This number will be used 
to identify the subject throughout the clinical study and must be used on all study 
documentation related to that subject.  The subject identification number must remain 
constant throughout the entire clinical study; it must not be changed at the time of 
rescreening or enrollment. 
Subjects who are determined not eligible after screening must be screen-failed in the 
ETO system and the reason for the screen-failure provided.  Subjects who do not meet 
all eligibility criteria may be rescreened once at the discretion of the investigator.  If a 
subject is being rescreened, he or she may need to reconsent to the study to ensure that 
the IRB/IEC-approved main informed consent form is signed within 28 days of 
enrollment.  Subjects who are determined not eligible after rescreen must be 
screen-failed in the ETO system and the reason for the screen-failure provided.  
Subjects may be enrolled only once into this study. 
Upon confirmation of eligibility, the site staff will use the ETO system to enroll a subject.  
A subject will be considered enrolled when the investigator confirms that the subject has 
met all eligibility criteria and the subject is registered as enrolled in the ETO system.  
The investigator is to document confirmation of eligibility in the subject’s medical record 
and in the case report form (CRF).

seal, and polypropylene cap.  Each vial contains a minimum of 1.0 mL talimogene 
laherparepvec at either 10⁶ PFU/mL  or 10⁸ PFU/mL concentrations.  The supply for 
10⁶ PFU/mL concentration will be packaged separately from the supply for 10⁸ PFU/mL 
concentration.  Additional details on talimogene laherparepvec packaging and 
formulation are provided in the Investigational Product Instruction Manual. 
6.2.1.1 
Dosage, Administration, and Schedule 
Talimogene laherparepvec must be prepared and administered by a qualified healthcare 
professional.  Subjects should be assessed clinically for adverse events/toxicity prior to 
each dose using the Common Terminology Criteria for Adverse Events (CTCAE) 
version 3.0 (Appendix A).  Complete blood count with differential and chemistry panels 
including liver function laboratory tests (such as ALT, AST, and total bilirubin) should be 
obtained according to the Schedule of Assessments (see Table 2) and the results should 
be checked before scheduled doses as per the requirements described in the 
Schedule of Assessments.  Dosing will occur only if these test values are acceptable, 
per Section 6.2.1.2. 
Talimogene laherparepvec will be administered by intralesional injection only into 
injectable cutaneous, subcutaneous, and nodal tumors, with or without image ultrasound 
guidance.  Talimogene laherparepvec must not be administered into visceral organ 
metastases.  The initial dose of talimogene laherparepvec is up to 4.0 mL of 
106 PFU/mL.  Subsequent doses of talimogene laherparepvec are up to 4.0 mL of 
108 PFU/mL. 
The first cycle of talimogene laherparepvec will be 21 (+ 5) days.  Subsequent cycles of 
talimogene laherparepvec will be 14 (± 3) days.  On day 1 of cycle 1 the first dose of 
talimogene laherparepvec will be up to 4.0 mL of 106 PFU/mL.  The second injection up 
to 4.0 mL of 108 PFU/mL, should be administered 21 (+ 5) days after the initial injection 
(ie, no sooner than day 22 but should not be delayed more than 5 days after the 21-day 
time point).  Subsequent injections up to 4.0 mL of 108 PFU/mL should be given every 
14 (± 3) days. 
The maximum volume of talimogene laherparepvec administered at any dose is 4.0 mL 
for any individual lesion.  The maximum dose in any treatment is 4.0 mL.  Investigators 
are encouraged to use the maximum amount whenever lesions allow.  Dose reduction 
for adverse events is not allowed.  However, if in the course of administration of 
talimogene laherparepvec the subject cannot tolerate the full dose due to an

injection-related adverse event such as pain, the total volume given should be recorded, 
and the reason for intolerance should be documented as an adverse event. 
The recommended volume of talimogene laherparepvec to be injected into the tumor(s) 
is dependent on the size of the tumor(s) and should be determined according to the 
injection volume guideline in Table 1.  The tumor size assessment should be done by 
clinical exam using ruler or caliper for cutaneous and palpable and protruding 
subcutaneous and nodal lesions, or by measurements under ultrasound of deep-seated 
subcutaneous and nodal lesions.

At baseline, if there are ≥ 2 lesions, one cutaneous, subcutaneous or nodal lesion 
(ie, the lesion considered lowest priority for injection) should be left uninjected at least 
until it is biopsied at week 6  (see Section 7.2.2).  (No biopsy will be taken at week 6 
for subjects with 1 lesion present at baseline).  All other reasonably injectable lesions 
(cutaneous, subcutaneous, and nodal disease that can be injected with or without 
ultrasound guidance) should be injected with the maximum dosing volume available on 
an individual dosing occasion (Table 1).  On each treatment day, prioritization of 
injections is recommended as follows (aside from leaving one lesion uninjected until it is 
biopsied at week 6): 
• 
any new injectable tumor that has appeared since the last injection 
• 
by tumor size, beginning with the largest tumor  
• 
any previously uninjectable tumor(s) that is now injectable, including the previously 
uninjected lesion(s) after the biopsy at week 6 if now injectable 
It is recommended that each lesion should receive the maximum amount possible to 
inject due to tumor properties at each visit before moving on to the next lesion, using the 
prioritization model above and the injection volume guideline based on tumor size per  
Table 1.  Lesions should be injected until the maximum volume per day (4.0 mL) has 
been reached or there are no further injectable lesions, whichever comes first.

A subject will be treated with talimogene laherparepvec until the subject has achieved a 
CR, all injectable tumors have disappeared, clinically significant (resulting in clinical 
deterioration or requiring change of therapy) disease progression beyond 6 months of 
treatment, per modified World Health Organization (WHO) response criteria 
(Appendix D), or intolerance of study treatment, whichever occurs first.  Due to the 
mechanism of action, subjects may experience growth in existing tumors or the 
appearance of new tumors prior to maximal clinical benefit of talimogene laherparepvec.  
Therefore, dosing should be continued for at least 6 months from the time of initial dose, 
provided that the subject has no evidence of clinically significant deterioration of health 
status requiring discontinuation of treatment with talimogene laherparepvec and is able 
to tolerate the treatment. 
The dose, start date, and lot number of talimogene laherparepvec are to be recorded on 
the electronic case report form (eCRF). 
6.2.1.2 
Dosage Adjustments, Delays, Rules for Withholding or Restarting, 
Permanent Discontinuation  
Dose reductions of talimogene laherparepvec are not permitted, other than with respect 
to a reduction in the volume injected due to a disease response. 
If a subject experiences any of the following treatment-related toxicities, talimogene 
laherparepvec administration should be delayed until the toxicity has resolved to at least 
CTCAE grade 1 or has returned to baseline: 
• 
grade 2 or greater immune-mediated adverse events, with the exception of vitiligo 
• 
grade 2 or greater allergic reactions 
• 
any other grade 3 or greater hematologic or non-hematologic toxicity  
Subjects who are receiving talimogene laherparepvec may not receive systemic 
antiherpetic drugs (eg, acyclovir, valacyclovir, famciclovir), but may receive a topically 
administered antiherpetic drug more than 20 cm from a talimogene laherparepvec 
injection site.  If a subject requires treatment with systemic antiherpetic drugs 
(eg, acyclovir, valacyclovir, famciclovir) talimogene laherparepvec should be 
witheld and the investigator or designee should notify the Amgen medical monitor 
as soon as possible.  Subject may be allowed to continue treatment after 
discussion between the Amgen medical monitor and the investigator to determine 
the appropriateness of treatment resumption.

Dosing should be permanently discontinued if, in the opinion of the investigator, the 
subject develops clinical evidence of any systemic herpes infection (such as encephalitis 
or disseminated infection).  
If the subject requires corticosteroid dosing of > 10 mg prednisone daily (or equivalent) 
for related toxicities, talimogene laherparepvec dosing must be withheld until the 
corticosteroid dose has decreased to ≤ 10 mg prednisone daily (or equivalent). 
All necessary supportive care shall be available to subjects except for those listed in 
Section 6.8.  Talimogene laherparepvec treatment should be continued based on the 
potential benefit/risk assessment of the subject. 
If talimogene laherparepvec treatment is delayed by >1 week, that dose will be deemed 
to have been missed and the subject will proceed to the next scheduled treatment visit.  
If talimogene laherparepvec dosing is delayed by more than 4 weeks from the date of 
the planned dose (ie, approximately 6 weeks from the previous dose) due to the 
occurrence of an adverse event that is considered related to talimogene laherparepvec, 
the subject must be permanently withdrawn from talimogene laherparepvec treatment.  
If talimogene laherparepvec dosing is delayed by more than 4 weeks from the date of 
the planned dose (ie, approximately 6 weeks from the previous dose) for reasons other 
than treatment-related toxicity, the case must be reviewed by the Amgen medical 
monitor in conjunction with the investigator to determine if the subject can resume 
talimogene laherparepvec therapy. 
Talimogene laherparepvec is to be permanently discontinued for subjects meeting any of 
the following criteria: 
• 
The subject, for any reason, requires treatment with another anticancer therapeutic 
agent for treatment of the study disease (other than the exceptions noted in 
Section 6.5).  In this case, discontinuation from the treatment occurs immediately 
upon introduction of the new agent.  
• 
Clinically relevant disease progression beyond 6 months of treatment occurs as 
defined per the modified WHO response criteria (Appendix D).  
• 
A grade 2 or greater immune-mediated adverse event (with the exception of vitiligo) 
or allergic reactions attributed to talimogene laherparepvec that would require a dose 
delay of greater than 4 weeks from the date of the planned dose (ie, approximately 
6 weeks from the previous dose). 
Note:  immune-mediated glomerulonephritis, vasculitis, and pneumonitis and 
exacerbation of psoriasis have been observed in subjects receiving talimogene 
laherparepvec in clinical trials.  Most of these subjects had a history of other 
autoimmune disease and/or prior treatment with agents that offered plausible

alternative etiologies, however, immune-mediated adverse events can potentially 
involve any organ system.  
• 
Any other talimogene laherparepvec-related non-hematologic or hematologic 
toxicities grade 3 or greater occur that, in the opinion of the investigator, would 
require a dose delay of greater than 4 weeks from the date of the planned dose 
(ie, approximately 6 weeks from the previous dose). 
• 
The subject develops clinical evidence of any systemic herpes infection (such as 
encephalitis or disseminated infection). 
• 
A female subject becomes pregnant or fails to use acceptable method(s) of effective 
contraception (for those subjects who are able to conceive) including but not 
limited to male or female latex condom to avoid potential viral transmission 
during sexual contact. 
• 
A female subject breast feeds while on study treatment. 
• 
Concurrent medical illness that, in the judgment of the investigator, would make 
continued treatment with talimogene laherparepvec dangerous for the subject. 
For additional information related special warnings and precautions for the use of 
talimogene laherparepvec please refer to the latest version of the Talimogene 
Laherparepvec Investigator’s Brochure. 
6.3 
Other Protocol-required Therapies 
All other protocol-required therapies including topical anesthetic or an injectable local 
anesthetic medications used for pretreatment of the talimogene laherparepvec injection 
site that are commercially available are not provided or reimbursed by Amgen (except if 
required by local regulation).  The investigator will be responsible for obtaining supplies 
of these protocol-required therapies. 
Additional details regarding these protocol-required therapies are provided in the IPIM. 
6.4 
Concomitant Therapy  
Throughout the study, investigators may prescribe any concomitant medications or 
treatments deemed necessary to provide adequate supportive care except for those 
listed in Section 6.8. 
All prescription and nonprescription concomitant medication administered up to 28 days 
prior to enrollment, on an ongoing basis after enrollment, as well as changes in such 
concomitant medication, and any new concomitant medication taken while the subject is 
on study, should be recorded on the appropriate case report form (CRF) until 30 days 
(+ 7 days) after the last dose of talimogene laherparepvec.  The therapy name, 
indication, dose, unit, frequency, start date, and stop date will be collected.

Investigators should use supportive care agents in compliance with their respective 
regional label.  Investigators may not use supportive care agents as part of a separate 
clinical trial. 
6.5 
Other Treatment Procedures 
Treatment with talimogene laherparepvec may result in the reduction of tumor burden 
such that surgical resection of previously unresected lesion becomes possible.  
Investigators may choose to resect lesions which become suitable for resection to 
render the subject free of macroscopic disease.  Additionally, biopsies will be taken of 
cutaneous, subcutaneous or nodal lesions for tumor analysis during study.  In the event 
of a complete response, residual visible cutaneous or subcutaneous index lesions must 
be documented by representative biopsy to not contain viable tumor.  If a subject 
undergoes resection of the lesion in the event other than CR, the investigator or 
designee should notify the sponsor medical monitor as soon as possible and the 
procedure should be recorded in the source document and eCRF.  In these instances, if 
the response of other lesions is at least PR (if other lesions remain), the response 
should be designated PR with the date of surgery as the date of response.  If no residual 
disease remains following surgery, this should also be noted in the eCRF, the response 
definition again being PR with the date of surgery as the date of response.  If no 
viable melanoma was found in the surgical specimen and all other tumor lesions 
resolved completely (if were present), the response definition will be CR with the 
date of surgery as the date of response. 
Local palliative radiation treatment for relief of various symptoms including, but not 
limited to, bleeding or pain associated with the underlying disease will be permitted at 
any time during the study.  Subjects with local symptoms suggestive of disease 
progression should be evaluated for tumor response per modified WHO response 
criteria (see Appendix D) prior to the administration of palliative radiotherapy.  If a 
subject undergoes local radiation, the investigator or designee should notify the sponsor 
medical monitor as soon as possible and the treatment should be recorded in the source 
document and eCRF.  
If a subject demonstrates evidence of recurrent or new central nervous system (CNS) 
metastases, talimogene laherparepvec should be withheld and the investigator or 
designee should notify the Amgen medical monitor as soon as possible.  Subjects may 
be allowed to remain on protocol after discussion between the Amgen medical monitor 
and the investigator to determine the appropriateness of treatment resumption provided

CONFIDENTIAL 
 
 
CNS lesions can be treated with stereotactic radiotherapy (including GammaKnife) or 
resection and if there is no change in the baseline ECOG performance status.  Subjects 
may be allowed to reinitiate talimogene laherparepvec following treatment of CNS 
metastases while receiving dexamethasone or a similar corticosteroid at no more than 
1.5 mg dexamethasone (or 10 mg prednisone or equivalent) per day.  If higher doses of 
a steroid are used, talimogene laherparepvec must be held until that dose level is 
reached during the period of steroid tapering. 
6.6 
Medical Devices 
Medical devices (eg, syringes, sterile needles, alcohol prep pads), that are commercially 
available are not usually provided or reimbursed by Amgen (except if required by local 
regulation).  The investigator will be responsible for obtaining supplies of these devices.   
6.7 
Product Complaints 
A product complaint is any written, electronic or oral communication that alleges 
deficiencies related to the identity, quality, durability, reliability, safety, effectiveness, or 
performance of any investigational or non-investigational product(s) or device(s). 
Any product complaint(s) associated with an investigational product(s) or 
non-investigational product(s) or device(s) supplied by Amgen are to be reported 
according to the instructions provided in the IPIM. 
6.8 
Excluded Treatments and/or Procedures During Study Period  
Subjects must not use any of the following therapies during screening or treatment 
period: 
• 
other investigational agents or procedures   
• 
concurrent experimental or approved anti-tumor therapies other than study drug and 
radiation therapy required for palliation (as noted in Section 6.5)  
• 
chronic oral or systemic steroid medication use at a dose of >10 mg/day of 
prednisone or equivalent (with the exception of treatment for adverse events 
[see Section 6.2.1.2] and CNS metastases [see Section 6.5]).  Steroids with low 
systemic absorption [eg, triamcinolone hexacetonide] injected into a joint space is 
allowed) 
• 
antiherpetic drugs (eg, acyclovir), other than if topically administered > 20 cm from a 
talimogene laherparepvec injection site.  If a subject requires treatment with a 
systemic antiherpetic drugs (eg, acyclovir, valacyclovir, famciclovir) 
talimogene laherparepvec should be witheld and the investigator or designee 
should notify the Amgen medical monitor as soon as possible.  Subject may 
be allowed to continue treatment after discussion between the Amgen medical 
monitor and the investigator to determine the appropriateness of treatment 
resumption.

• 
Subjects must not schedule any elective surgeries during the treatment period and 
for at least 30 days after the last administration of study drug.  If a subject undergoes 
any unexpected surgery during the course of the study, study treatment must be 
withheld and the investigator or designee should notify the sponsor medical monitor 
as soon as possible.  A subject may be allowed to resume study drug if both the 
investigator and sponsor medical monitor agree to restart study therapy. 
The exclusion criteria describe other medications and procedures which are prohibited in 
this study (refer to Sections 4.1.2). 
There are no prohibited therapies and procedures during the post treatment long-term 
follow-up period.

f  All nonserious adverse events (related or not related to talimogene laherparepvec) that occur after the first dose through 30 (+7) days after the last 
administration of talimogene laherparepvec will be recorded in the case report form.  In addition, all adverse events deemed by the investigator to be potentially 
related to talimogene laherparepvec will be recorded in the case report form through the survival follow-up.  Adverse events should be assessed on an 
ongoing basis and recorded at each subject visit.  All serious adverse events that occur after the subject has signed the informed consent through 30 (+7) days after 
the last administration of talimogene laherparepvec will be reported to Amgen and recorded in the case report form.  Serious adverse events must be reported to 
Amgen within 24 hours of discovery. 
g  Physical examination as per standard of care. 
h  Vital signs (blood pressure, heart rate, and temperature) must be performed at screening, prior to talimogene laherparepvec administration on day 1 of cycle 
1, 2, and 4, then every other cycle (Q2C) until end of treatment, and at the safety follow-up visit. 
i  Urine or serum pregnancy test must be performed on females of childbearing potential within 3 days prior to enrollment and at the safety follow-up visit.  Note:  
Additional on-treatment pregnancy testing may be performed at the investigator’s discretion or as defined in a country-specific protocol supplement at the end of the 
Appendix Section of the protocol as required per local laws and regulations. 
j  Blood samples for hematology will be collected at screening, within 3 days prior to talimogene laherparepvec administration on day 1 of cycles 1, 2, and 3,then every 
4th cycle (Q4C) until end of treatment, and at the safety follow-up visit.  Results must be reviewed prior to scheduled dose of study treatment. 
k  Blood samples for chemistry will be collected at screening, within 3 days prior to talimogene laherparepvec administration on day 1 of cycles 1, 2, and 3, then every 
4th cycle (Q4C) until end of treatment, and at the safety follow-up visit.  Results must be reviewed prior to scheduled dose of study treatment. 
l   Archived formalin-fixed paraffin-embedded tumor tissue (block or unstained tumor slide) from either the primary tumor or a metastatic lesion, and the associated 
pathology reports should be submitted to the central laboratory within 28 days after enrollment for biomarker analyses.  BRAF V600E/K mutation status may be obtained 
in a number of ways.  For previously Known BRAF V600E/K Tumor Status,  BRAF V600E/K tumor status result, obtained from a local laboratory prior to screening for this 
study will be acceptable.  For previously Unknown BRAF V600E/K Tumor Status, archived formalin-fixed paraffin-embedded tumor tissue (block or unstained tumor 
slide) from either the primary tumor or a metastatic lesion should be analyzed at a local laboratory or submitted to the central laboratory within 28 days after 
enrollment. 
m  Swabs of any lesion suspected to be herpetic in origin will be collected as follows:  Subject should return to clinic within 3 days of the occurrence of reportable lesion 
suspected to be herpetic in origin, such as cold sores or vesicles.  The lesion should be evaluated by the investigator and swabbed if herpetic infection is suspected.  
A qPCR analysis will be performed at a central lab on the swab to evaluate whether the talimogene laherparepvec DNA is detectable in the sample. 
n  Blood sample for HSV serostatus will be collected (within 3 days prior to talimogene laherparepvec administration) at day 1 of week 1 [Cycle 1], week 6 [Cycle 3], 
and week 12 [Cycle 6].   
o  Blood sample for biomarker analysis will be collected (within 3 days prior to talimogene laherparepvec administration) at day 1 of week 1 [Cycle 1], week 6 [Cycle 3], 
week 12 [Cycle 6], and week 24 [Cycle 12]. 
p  Tumor biopsy from cutaneous, subcutaneous or nodal lesions for biomarker analysis should not be collected prior to the subject being enrolled.  Tumor 
biopsy should be collected (within 5 days prior to first talimogene laherparepvec administration) from one lesion at day 1 of week 1 [Cycle 1] and, if there are 
≥ 2 lesions at baseline and one is left uninjected as described in Section 6.2.1.1, from an uninjected lesion within 7 days prior to dose at day 1 of week 6 [Cycle 3].  
Also within 7 days after documentation of disease progression followed by treatment discontinuation from the available cutaneous, subcutaneous or nodal 
lesion responsible for PD and easily accessible for biopsy with or without unltrasound guidance.  Note:  uninjected lesion biopsied at day 1 of week 6 [Cycle 3] 
must be different lesion from the lesion biopsied at day 1 of week 1 [Cycle 1]. 
q  Investigator’s clinical measurement of cutaneous, subcutaneous, or nodal tumor by caliper at screening, day 1 of week 12 (± 1 week) [Cycle 6] and then every 
12 weeks (± 1 week), or more frequently if clinically indicated, until clinically relevant disease progression beyond 6 months of treatment (per modified WHO response 
criteria, Appendix D) or until the start of a new anticancer therapy.  The screening measurement must be done within 28 days prior to enrollment and will be used as 
baseline.  If subject discontinues talimogene laherparepvec for reason other than disease progression or death, clinical tumor measurements are to be performed at 
safety follow-up visit (if not performed within previous 4 weeks [+ 1 week]) and every 12 weeks (±1week) during the long term follow-up period until clinically relevant 
disease progression beyond 6 months of treatment (per modified WHO response criteria, Appendix D) or until the start of a new anticancer therapy.

treatment (always within 3 days prior to investigational product administration).  See Section 7.2.6  
t  The first cycle of talimogene laherparepvec will be 21 (+ 5) days.  Subsequent cycles of talimogene laherparepvec will be 14 (± 3) days (QC).  On day 1 of cycle 1, 
the first dose of talimogene laherparepvec will be up to 4.0 mL of 106 PFU/mL.  The second injection up to 4.0 mL of 108 PFU/mL should be administered 21 (+ 5) 
days after the initial injection (ie, no sooner than day 22 but should not be delayed more than 5 days after the 21-day time point).  Subsequent injections up to 4.0 mL 
of 108 PFU/mL should be given every 14 (± 3) days.  Subjects will be treated with talimogene laherparepvec until the subject has achieved a complete response, all 
injectable tumors have disappeared, clinically significant (resulting in clinical deterioration or requiring change of therapy) disease progression beyond 6 months of 
treatment, per modified WHO response criteria (Appendix D), or intolerance of study treatment, whichever occurs first. 
u  Reporting potential or known unintended exposure to talimogene laherparepvec:  If a household member, caregiver, or healthcare provider who has had close 
contact with the subject is suspected to have been exposed to talimogene laherparepvec (eg,  have or who have had signs or symptoms suspected to be herpetic 
origin or accidentally exposed to talimogene laherparepvec), report the potential or known unintended exposure to talimogene laherparepvec, suspected related 
signs or symptoms, and detection of talimogene laherparepvec in a subject’s household member, caregiver, or healthcare provider as specified in Section 9.4

General Study Procedures  
A signed and dated IRB/IEC-approved informed consent must be obtained before any 
study specific procedures are performed.  Procedures that are part of routine care are 
not considered study specific procedures and may be used at screening to determine 
eligibility.  All subjects will be screened for eligibility before enrollment.  Only eligible 
subjects will be enrolled into the study. 
During treatment, assessments and procedures can be performed within 3 days of the 
planned visit unless specified otherwise.  It is recommended that dosing occur on the 
same day of the week (eg, if first dose is administered on Monday, all subsequent doses 
should be administered on a Monday), however a ± 3 day dosing and study procedure 
window is allowed. 
The following laboratory analytes in Table 3 will be assessed at various times throughout 
the study:

Long-term Follow-up/End of Study 
All subjects who permanently discontinue talimogene laherparepvec for any reason 
other than withdrawal of full consent or death will be contacted by telephone, or clinic 
visit, to assess survival status and, if applicable, commencement of any subsequent 
anticancer melanoma therapy.  Adverse events deemed by the investigator to be 
potentially related to talimogene laherparepvec and use of anti-cancer therapies 
for melanoma will also be recorded.  Follow-up will occur every 12 weeks (± 28 days) 
following the safety follow-up visit until death, subject withdraws full consent, or up to 
24 months after the last subject is enrolled in the study. 
If subject has discontinued talimogene laherparepvec for reason other than disease 
progression or death, radiographic tumor imaging, clinical tumor assessments, ECOG 
Performance Status assessments, reporting of pregnancy or lactation, 
assessment of swabs of lesions of suspected herpetic origin for presence of 
talimogene laherparepvec DNA by qPCR test, and tumor response assessments will 
be performed as documented in Section 7.2.2 until documented disease progression 
beyond 6 months of treatment, per modified WHO response criteria (Appendix D), until 
the start of a new anticancer therapy, or end of study, whichever the earliest. 
After the long term follow-up period of this study has ended, subjects who end the study 
for any reason other than death or withdrawal of full consent will be followed for survival

7.5 
Sample Storage and Destruction  
Any blood or tumor samples collected according to the Schedule of Assessments 
(Table 2) can be analyzed for any of the tests outlined in the protocol and for any tests 
necessary to minimize risks to study subjects.  This includes testing to ensure analytical 
methods produce reliable and valid data throughout the course of the study.  This can 
also include, but is not limited to, investigation of unexpected results, incurred sample 
reanalysis, and analyses for method transfer and comparability.  
All samples and associated results will be coded prior to being shipped from the site for 
analysis or storage.  Samples will be tracked using a unique identifier that is assigned to 
the samples for the study.  Results are stored in a secure database to ensure 
confidentiality. 
If informed consent is provided by the subject, Amgen can do additional testing on 
remaining samples (ie, residual and back-up) to investigate and better understand the 
cancer, the dose response and/or prediction of response to talimogene laherparepvec, 
characterize antibody response, and characterize aspects of the molecule 
(eg, mechanism of action/target, metabolites).  Results from this analysis are to be 
documented and maintained, but are not necessarily reported as part of this study.  
Samples can be retained for up to 20 years.   
Since the evaluations are not expected to be available in time to benefit the subject 
directly or to alter the treatment course, the results of qPCR testing from swabs of cold 
sores, vesicles, and other lesions suspected to be herpetic in origin will not be provided 
unless requested by the investigator or the subject.  Results may not be available until 
the end of the study.  Results of biomarker development or other exploratory studies are 
not placed in the subject’s medical record and are not to be made available to the 
subject, members of the family, the personal physician, or other third parties, except as 
specified in the informed consent. 
The subject retains the right to request that the sample material be destroyed by 
contacting the investigator.  Following the request from the subject, the investigator is to 
provide the sponsor with the required study and subject number so that any remaining 
blood or tumor samples and any other components from the cells can be located and 
destroyed.  Samples will be destroyed once all protocol-defined procedures are 
completed.  However, information collected from samples prior to the request for 
destruction, will be retained by Amgen.

The sponsor is the exclusive owner of any data, discoveries, or derivative materials from 
the sample materials and is responsible for the destruction of the sample(s) at the 
request of the subject through the investigator, at the end of the storage period, or as 
appropriate (eg, the scientific rationale for experimentation with a certain sample type no 
longer justifies keeping the sample).  If a commercial product is developed from this 
research project, the sponsor owns the commercial product.  The subject has no 
commercial rights to such product and has no commercial rights to the data, information, 
discoveries, or derivative materials gained or produced from the sample.  
See Section 11.3 for subject confidentiality. 
8. 
WITHDRAWAL FROM TREATMENT, PROCEDURES, AND STUDY 
8.1 
Subjects’ Decision to Withdraw 
Subjects have the right to withdraw from the study at any time and for any reason 
without prejudice to their future medical care by the physician or at the institution. 
Subjects (or a legally acceptable representative) can decline to continue receiving 
investigational product and/or other protocol-required therapies or procedures at any 
time during the study but continue participation in the study.  If this occurs, the 
investigator is to discuss with the subject the appropriate processes for discontinuation 
from investigational product or other protocol-required therapies and must discuss with 
the subject the options for continuation of the Schedule of Assessments (Table 2) and 
collection of data, including endpoints and adverse events.  The investigator must 
document the change to the Schedule of Assessments (Table 2) and the level of 
follow-up that is agreed to by the subject (eg, in person, by telephone/mail, through 
family/friends, in correspondence/communication with other physicians, from review of 
the medical records).   
Withdrawal of consent for a study means that the subject does not wish to receive 
further protocol-required therapies or procedures, and the subject does not wish to or is 
unable to continue further study participation.  Subject data up to withdrawal of consent 
will be included in the analysis of the study, and where permitted, publically available 
data can be included after withdrawal of consent.  The investigator is to discuss with the 
subject appropriate procedures for withdrawal from the study.

8.2 
Investigator or Sponsor Decision to Withdraw or Terminate 
Subjects’ Participation Prior to Study Completion 
The investigator and/or sponsor can decide to withdraw a subject(s) from investigational 
product and/or other protocol-required therapies, protocol procedures, or the study as a 
whole at any time prior to study completion.  
Subjects may be eligible for continued treatment with Amgen investigational product(s) 
and/or other protocol-required therapies by a separate protocol or as provided for by the 
local country’s regulatory mechanism, based on parameters consistent with 
Section 12.1. 
8.3

deviation, non-compliance (eg, procedural or dosing as defined in Section 6.2.1.1), 
requirement for alternative therapy, pregnancy) 
 
decision by sponsor (other than subject request or safety concern) 
 
death 
 
lost to follow-up 
 
clinically relevant disease progression beyond 6 months of treatment, per modified 
WHO response criteria (Appendix D) 
 
other protocol-specified criteria (Section 6.2.1.2) 
8.3.2 
Reasons for Removal From Study 
Reasons for removal of a subject from the study are: 
 
decision by sponsor

SAFETY DATA COLLECTION, RECORDING, AND REPORTING 
9.1 
Adverse Events 
9.1.1 
Definition of Adverse Events 
An adverse event is defined as any untoward medical occurrence in a clinical trial 
subject.  The event does not necessarily have a causal relationship with study treatment.  

Product:  Talimogene Laherparepvec 
Protocol Number:  20120325 
Date:  21 September 2015 
Page 55 of 90 
CONFIDENTIAL 
 
 
The investigator is responsible for ensuring that any adverse events observed by the 
investigator or reported by the subject are recorded in the subject’s medical record.   
The definition of adverse events includes worsening of a pre-existing medical condition.  
Worsening indicates that the pre-existing medical condition (eg, diabetes, migraine 
headaches, gout) has increased in severity, frequency, and/or duration, and/or has an 
association with a significantly worse outcome.  A pre-existing condition that has not 
worsened during the study or involves an intervention such as elective cosmetic surgery 
or a medical procedure while on study, is not considered an adverse event.   
For situations when an adverse event or serious adverse event is considered to be due 
to melanoma, report all known signs and symptoms.  Death due to disease progression 
in the absence of signs and symptoms should be reported as the primary tumor type 
(eg, worsening of melanoma).  
Note:  The term “disease progression” should not be used to describe the adverse event.   
The investigator’s clinical judgment is used to determine whether a subject is to be 
removed from treatment due to an adverse event.  In the event a subject, or subject’s 
legally acceptable representative requests to withdraw from protocol-required therapies 
or the study due to an adverse event, refer to Section 8.1 for additional instructions on 
the procedures recommended for safe withdrawal from protocol-required therapies or 
the study.   
9.1.2 
Definition of Serious Adverse Events 
A serious adverse event is defined as an adverse event that meets at least 1 of the 
following serious criteria: 
 
fatal 
 
life threatening (places the subject at immediate risk of death) 
 
requires in-patient hospitalization or prolongation of existing hospitalization 
 
results in persistent or significant disability/incapacity 
 
congenital anomaly/birth defect 
 
other medically important serious event 
An adverse event would meet the criterion of “requires hospitalization”, if the event 
necessitated an admission to a health care facility (eg, overnight stay).   
If an investigator considers an event to be clinically important, but it does not meet any 
of the serious criteria, the event could be classified as a serious adverse event under the 
criterion of “other medically important serious event”.  Examples of such events could

Protocol Number:  20120325 
Date:  21 September 2015 
Page 56 of 90 
CONFIDENTIAL 
 
 
include allergic bronchospasm, convulsions, blood dyscrasias, or events that necessitate 
an emergency room visit, outpatient surgery, or urgent intervention. 
9.2 
Reporting of Adverse Events 
9.2.1 
Reporting Procedures for Adverse Events That do not Meet Serious 
Criteria 
The investigator is responsible for ensuring that all adverse events observed by the 
investigator or reported by the subject that occur after the first dose of talimogene 
laherparepvec through 30 (+ 7) days after the last dose of talimogene laherparepvec are 
reported using the applicable eCRF (eg, Adverse Event Summary).  Adverse events 
deemed by the investigator to be potentially related to talimogene laherparepvec 
that occur during and after the first dose of talimogene laherparepvec and through 
the survival follow-up are to be reported.  
The investigator must assign the following adverse event attributes: 
 
adverse event diagnosis or syndrome(s), if known (if not known, signs or symptoms), 
 
dates of onset and resolution (if resolved), 
 
severity (and/or toxicity per protocol), 
 
assessment of relatedness to talimogene laherparepvec and 
 
action taken. 
The adverse event grading scale used will be the Common Terminology Criteria for 
Adverse Events (CTCAE), version 3.0.  The grading scale used in this study is described 
in Appendix A.  The investigator must assess whether the adverse event is possibly 
related to talimogene laherparepvec.  This relationship is indicated by a “yes” or “no” 
response to the question:  Is there a reasonable possibility that the event may have been 
caused by administration of investigational product?   
The investigator must assess whether the adverse event is possibly related to any 
study-mandated activity and/or procedure (eg, including any screening procedures).  
This relationship is indicated by a “yes” or “no” response to the question:  “Is there a 
reasonable possibility that the event may have been caused by a study activity and/or 
procedure”?  
The investigator is responsible for reviewing laboratory test results and determining 
whether an abnormal value in an individual study subject represents a clinically 
significant change from the subject’s baseline values.  In general, abnormal laboratory 
findings without clinical significance (based on the investigator's judgment) are not to be 
recorded as adverse events.  However, laboratory value changes that require treatment 

Product:  Talimogene Laherparepvec 
Protocol Number:  20120325 
Date:  21 September 2015 
Page 57 of 90 
CONFIDENTIAL 
 
 
or adjustment in current therapy are considered adverse events.  Where applicable, 
clinical sequelae (not the laboratory abnormality) are to be recorded as the adverse 
event. 
If the severity of an adverse event worsens from the date of onset to the date of 
resolution, record a single event for each increased level of severity on the Adverse 
Event Summary eCRF.  The investigator is expected to follow reported adverse events 
until stabilization or reversibility.  
9.2.2 
Reporting Procedures for Serious Adverse Events 
The investigator is responsible for ensuring that all serious adverse events observed by 
the investigator or reported by the subject that occur after signing of the informed 
consent through 30 (+ 7) days after the last dose of  talimogene laherparepvec are 
recorded in the subject’s medical record and are submitted to Amgen.  All serious 
adverse events must be submitted to Amgen within 24 hours following the investigator’s 
knowledge of the event via the applicable eCRF.  
After the protocol-required reporting period defined above, the investigator does not 
need to actively monitor subjects for serious adverse events.  However, if the 
investigator becomes aware of a serious adverse event after this protocol-required 
reporting period, the investigator will report the event to Amgen within 24 hours following 
the investigator’s knowledge of the event.  Serious adverse events reported outside of 
the protocol-required reporting period will be captured within the safety database as 
clinical trial cases for the purposes of expedited reporting.  
If the electronic data capture (EDC) system is unavailable to the site staff to report the 
serious adverse event, the information is to be reported to Amgen via an electronic 
Serious Adverse Event (eSAE) Contingency Report Form within 24 hours of the 
investigator’s knowledge of the event.  See Appendix B for a sample of the Serious 
Adverse Event Worksheet /electronic Serious Adverse Event Contingency Report Form.  
For EDC studies where the first notification of a Serious Adverse Event is reported to 
Amgen via the electronic Serious Adverse Event Contingency Report Form, the data 
must be entered into the EDC system when the system is again available. 
The investigator must assess whether the serious adverse event is possibly related to 
talimogene laherparepvec.  This relationship is indicated by a “yes” or “no” response to 
the question:  “Is there a reasonable possibility that the event may have been caused by 
the investigational product”?   

Product:  Talimogene Laherparepvec 
Protocol Number:  20120325 
Date:  21 September 2015 
Page 58 of 90 
CONFIDENTIAL 
 
 
The investigator must assess whether the serious adverse event is possibly related to 
any study-mandated activity or procedure.  This relationship is indicated by a “yes” or 
“no” response to the question:  “Is there a reasonable possibility that the event may have 
been caused by a study activity/procedure”?  
The investigator is expected to follow reported serious adverse events until stabilization 
or reversibility.  
New information relating to a previously reported serious adverse event must be 
submitted to Amgen.  All new information for serious adverse events must be sent to 
Amgen within 24 hours following knowledge of the new information.  The investigator 
may be asked to provide additional follow-up information, which may include a discharge 
summary or extracts from the medical record.  Information provided about the serious 
adverse event must be consistent with that recorded on the applicable CRF (eg, Adverse 
Event Summary eCRF). 
If a subject is permanently withdrawn from protocol-required therapies because of a 
serious adverse event, this information must be submitted to Amgen. 
Amgen will report serious adverse events and/or suspected unexpected serious adverse 
reactions as required to regulatory authorities, investigators/institutions, and IRBs/IECs 
in compliance with all reporting requirements according to local regulations and Good 
Clinical Practice (GCP).  
The investigator is to notify the appropriate IRB/IEC of serious adverse events occurring 
at the site and other adverse event reports received from Amgen, in accordance with 
local procedures and statutes. 
9.3 
Pregnancy and Lactation Reporting 
If a pregnancy occurs in a female subject, or female partner of a male subject, while the 
subject is taking protocol-required therapies, report the pregnancy to Amgen as specified 
below. 
In addition to reporting any pregnancies occurring during the study, investigators should 
report pregnancies that occur after the last dose of talimogene laherparepvec through 
3 months after the last dose of talimogene laherparepvec.  The pregnancy should be 
reported to Amgen Global Patient Safety within 24 hours of the investigator’s 
knowledge of the event of a pregnancy.  Report a pregnancy on the Pregnancy 
Notification Worksheet (Appendix B).   

Product:  Talimogene Laherparepvec 
Protocol Number:  20120325 
Date:  21 September 2015 
Page 59 of 90 
CONFIDENTIAL 
 
 
If a lactation case occurs while the female subject is taking protocol-required therapies 
report the lactation case to Amgen as specified below.  
In addition to reporting a lactation case during the study, investigators should monitor for 
lactation cases that occur after the last dose of talimogene laherparepvec through 
3 months after the last dose of talimogene laherparepvec. 
Any lactation case should be reported to Amgen Global Patient Safety within 24 hours 
of the investigator’s knowledge of event.  Report a lactation case on the Lactation 
Notification Worksheet (Appendix B). 
9.4 
Reporting of Exposure to Talimogene Laherparepvec 
If a household member, caregiver, or healthcare provider who has had close contact 
with the subject is suspected to have been exposed to talimogene laherparepvec 
(eg, have or who have had signs or symptoms suspected to be herpetic in origin or who 
have been accidentally exposed to talimogene laherparepvec), while the subject is 
taking talimogene laherparepvec, report the exposure to Amgen as specified below.  In 
addition to reporting an unintended exposure case during the study treatment, 
investigators should monitor for potential exposure cases that occur after the last dose of 
talimogene laherparepvec through 30 (+ 7) days after the last dose of talimogene 
laherparepvec.  Please refer to your study specific documents for reporting details. 
Any potential or known unintended exposure should be reported to Amgen within 
24 hours of the investigator’s knowledge of the event of exposure.  Amgen will seek to 
follow-up with the exposed individual, if necessary, to collect more information about the 
exposed individual contact with clinical trial subject, signs and/or symptoms related to 
the exposure, medical history, and/or outcome of the exposure.  If the exposed individual 
is reporting signs or symptoms suspected to be related to talimogene laherparepvec 
exposure, the exposed individual may be asked to have a swab taken to evaluate for the 
presence of talimogene laherparepvec in the lesion, within 3 days of the symptoms or 
signs occurring.

Sample Size Considerations 
All analyses will be descriptive with no formal hypothesis testing.  The sample size was 
selected based on practical considerations.  The primary objective of the study is to 
assess whether baseline intratumoral CD8+ cell density is correlated with the likelihood 
of response to talimogene laherparepvec.  Analyses for the objective will focus on 
whether the response rate varies with baseline intratumoral CD8+ cell density.  The 
functional manner in which the response rate may vary with the biomarker is unknown, 
therefore multiple functional relationships may be examined.  It is assumed that 
100 subjects (approximately 91% of the enrolled) will have an evaluable baseline 
intratumoral CD8+ cell density.  The adequacy of the sample size was evaluated for one 
of several possible analyses that evaluates whether the response rate is positively 
correlated with a high baseline intratumoral CD8+ cell density where a low and high 
biomarker is defined as a value below versus at or above the sample median, 
respectively.  A one-sided Fisher’s Exact test will be performed at a 5% nominal level to 
explore the hypothesis that the response rate is equal regardless of baseline 
intratumoral CD8+ cell density.  The overall ORR is assumed to be 26.4%.  The power 
for the test will depend on the true response rates in the biomarker subgroups.  
Assuming the true response rate is 13.2% in the biomarker low subgroup, and 39.6% in 
the biomarker high subgroup, the power will be 88% to detect a positive association.  
A secondary objective of this study is to estimate the objective response rate.  Based on 
the analysis of the OPTiM study, the overall response rate for stage IIIB/C and IVM1c is 
assumed to be around 26.4% where, among responders, the probability of response 
onset after 12 months was < 5%.  The expected exact 95% CIs for various true ORRs 
are listed in Table 4.  The expected width of the 95% CI is around 18% under these 
scenarios.

Another secondary objective is to explore the correlation between changes in 
intratumoral CD8+ cell density during treatment and objective response rate.  The 
primary focus will be on changes in tumor cell CD8+ density.  It is assumed that 
55 subjects (approximately 50% of all enrolled) will be evaluable with a pre- and 
on-treatment lesion biopsy that is sufficient to evaluate biomarker changes in uninjected 
lesions.  In addition to correlating biomarker changes with objective response, Pearson’s 
correlation coefficient (r) will also be estimated between the biomarker change and the 
maximum decrease in index lesions.  With 55 evaluable subjects, a value of r ≤ 0.30 will 
be rejected at a nominal 1-sided 5% significance level with an observed r > 0.49 for 
which the power will be > 80% given a true value for r ≥ 0.60.

Planned Analyses 
10.3.1 
Interim Analyses 
An interim analysis to evaluate the study objectives of correlation between the 
biomarker (ie baseline intratumoral CD8+ cell density changes in intratumoral 
CD8+ cell density and other biomarkers) and ORR will be conducted on 
approximately the first 50 subjects only who received at least 1 dose of 
talimogene laherparepvec, with the biomarker recorded at baseline, and have had 
the opportunity to be on study (treatment or follow-up phase) for at least 
6 months.  The study will not be discontinued due to the results of this interim 
analyses; however, predictive hypotheses generated from the interim analysis 
may lead to subsequent changes to study conduct. For example, if the interim 
analysis suggests an enhanced effect in a biomarker-defined subgroup, then the 
protocol and statistical analysis plan may be revised to ensure the study can 
adequately evaluate the subgroup effect.  Revisions may also happen due to 
obtaining new relevant data from external sources, such as scientific publications 
and communications.

10.3.2 
Primary Analysis 
The clinical study report (CSR) will be written based on the results of the primary 
analysis.  The main goals of the primary analysis are to evaluate the ORR and 
correlation of baseline intratumoral CD8+ cell density and the likelihood of response to 
talimogene laherparepvec, in addition to the correlation between changes in intratumoral 
CD8+ cell density during treatment and objective response.  The timing of the primary 
analysis will be when all subjects have had the opportunity to complete 12 months of 
treatment of talimogene laherparepvec. 
10.3.3 
Final Analysis 
The final analysis will occur either 24 months after the last subject has been enrolled 
or when the last subject discontinues the study treatment and has had the opportunity to 
complete the safety follow–up, whichever is later.  The CSR will be amended with the 
updated results from the final analysis at the completion of the study. 
10.4 
Planned Methods of Analysis 
Descriptive statistics will be provided for demographic, safety, efficacy, and biomarkers 
as appropriate.  In general, the safety analysis set will be used for all safety analyses.  
The safety analyses include incidence of treatment-emergent and treatment related 
adverse events (all adverse events, ≥ grade 3 adverse events, serious adverse events, 
fatal adverse events and adverse events defined as events of interest). 
The efficacy analysis will be conducted using the safety analysis set as well unless 
otherwise specified.  The ORR will be estimated with the associated 95% CI.  
Descriptive statistics for DRR, time to treatment failure and OS will be provided.  In 
addition, DOR and changes in tumor burden for responders will also be summarized. 
The correlation between a baseline biomarker and response rate will be evaluated.  The 
functional manner in which the response rate may vary with the biomarker is unknown; 
therefore multiple functional relationships may be examined.  Pearson’s correlation 
coefficient (r) will be estimated between the biomarker change and the maximum 
decrease in index lesions to evaluate the correlation between changes in a biomarker 
post-treatment and the effect of treatment on measurable lesions, in addition to 
correlating biomarker changes with objective response using logistic regression. 
10.4.1 
Primary Endpoint 
The primary endpoint of the study is the correlation between baseline intratumoral 
CD8+ cell density and objective response rate (ORR).  The correlation of intratumoral

CD8+ cell density and other biomarkers with ORR will be evaluated as described in 
Section 10.4 for ORR and DRR. 
10.4.2 
Secondary Endpoint (s) 
Multiple biomarkers will be examined to assess the correlation between their baseline 
value and DRR, DOR, and changes in tumor burden as well as the changes in their 
value during treatment with ORR, DRR, DOR, and changes in tumor burden.  The 
functional manner in which the ORR, DRR, DOR, and change in tumor burden may vary 
with each biomarker is unknown, therefore multiple functional relationships will be 
examined to assess overall evidence of an association.  Combinations of biomarkers 
may be explored to assess their predictive value for patient selection.  Example analyses 
include, but are not limited to:  (a) the correlation of baseline value as a continuous 
variable with the odds of OR, DR or the hazard of ending response; (b) a trend test for 
an increasing ORR, DRR with pre-specified, ordered biomarker categories, (c) a test that 
the ORR, DRR or hazard of ending response is greater between subgroups of subjects 
with a high vs. low baseline biomarker value for all possible cut-points for a minimum 
high biomarker value, (d) a receiver operating characteristic (ROC) analysis (categorical 
and continuous biomarker values), and (e) calculation of negative predictive value (NPV) 
and positive predictive value (PPV) for each candidate cut-point for ORR and DRR.   
In order to evaluate the correlation between changes in biomarkers during treatment and 
the effect of treatment on measurable lesions, Pearson’s correlation coefficient (r) will be 
estimated between the biomarker change and the maximum decrease in index lesions, 
in addition to correlating biomarker changes with ORR/DRR using logistic regression, 
and duration of response using Cox model regression. 
Overall survival (OS), duration of response and time to treatment failure will be 
summarized by K-M methods.  Durable response rate and objective response rate will 
be presented with 95% CI. 
10.4.3 
Safety Endpoints 
Subject incidence rates of treatment-emergent adverse events (including all adverse 
events, grade ≥ 3 adverse events, serious adverse events, adverse events of interest 
and events requiring the discontinuation of study drug, and local effects on the tumor 
[ie, pain, inflammation and ulceration]) will be summarized.  Medical Dictionary for 
Regulatory Activities (MedDRA) will be used to code adverse events to a system organ 
class (SOC) and a preferred term within the SOC.  The CTCAE version 3.0 will be used 
to grade severity of adverse events.  In addition clinically significant laboratory changes

and clinically significant changes in vital signs will be summarized with descriptive 
statistics.  Summary statistics will also be provided for concomitant medications, dose 
delay, study drug discontinuation, overall exposure, and changes in ECOG performance 
status.  Tables and/or narratives of deaths after initiation of the study through 30 days 
since the last dose of talimogene laherparepvec will be provided. 
The qPCR analysis result of talimogene laherparepvec DNA in swab samples taken from 
cold sore, vesicles, and other lesions suspected to be herpetic in origin (if any) will be 
summarized descriptively. 
Potential or known unintended exposure to talimogene laherparepvec, related suspected 
signs or symptoms, and detection of talimogene laherparepvec in a subject’s household 
member, caregiver, or healthcare provider will be reported. 
10.4.4 
Exploratory Endpoints 
Correlation between the changes in the population of tumor specific cytotoxic T-cells and 
immunoscore during treatment and clinical response will be assessed by the same 
methods described in Section 10.4.  In addition, other potential blood and tumor 
biomarkers which predict ORR will be explored similarly.  
10.5 
Handling of Missing and Incomplete Data 
Partial or missing dates of adverse events and concomitant medications will be imputed.  
Adverse events with missing severity and/or possible relationship to talimogene 
laherparepvec will be included in the all adverse events analyses, except by severity 
grade and treatment-related.  Every effort will be made to obtain complete dates for 
deaths.  Details of the imputation algorithms will be specified in the study-specific 
statistical analysis plan.

termination of the study and before the product(s) is/are available commercially. 
12.2 
Study Documentation and Archive 
The investigator is to maintain a list of appropriately qualified persons to whom he/she 
has delegated study duties.  All persons authorized to make entries and/or corrections 
on eCRFs will be included on the Amgen Delegation of Authority Form. 
Source documents are original documents, data, and records from which the subject’s 
eCRF data are obtained.  These include but are not limited to hospital records, clinical 
and office charts, laboratory and pharmacy records, diaries, microfiches, radiographs, 
and correspondence. 
In this study, the ETO system captures the following data points and these are 
considered source data:  subject identification.  
eCRF entries may be considered source data if the eCRF is the site of the original 
recording (ie, there is no other written or electronic record of data). 
The investigator and study staff are responsible for maintaining a comprehensive and 
centralized filing system of all study-related (essential) documentation, suitable for 
inspection at any time by representatives from Amgen and/or applicable regulatory

Retention of study documents will be governed by the Clinical Trial Agreement. 
12.3 
Study Monitoring and Data Collection 
The Amgen representative(s) and regulatory authority inspectors are responsible for 
contacting and visiting the investigator for the purpose of inspecting the facilities and, 
upon request, inspecting the various records of the clinical study (eg, eCRFs and other 
pertinent data) provided that subject confidentiality is respected. 
The Amgen clinical monitor is responsible for verifying the eCRFs at regular intervals 
throughout the study to verify adherence to the protocol; completeness, accuracy, and 
consistency of the data; and adherence to local regulations on the conduct of clinical 
research.  The clinical monitor is to have access to subject medical records and other 
study-related records needed to verify the entries on the eCRFs. 
The investigator agrees to cooperate with the clinical monitor to ensure that any 
problems detected in the course of these monitoring visits, including delays in 
completing eCRFs, are resolved. 
In accordance with ICH GCP and the sponsor’s audit plans, this study may be selected 
for audit by representatives from Amgen’s Global R&D Compliance and Audit function 
(or designees).  Inspection of site facilities (eg, pharmacy, protocol-required therapy 
storage areas, laboratories) and review of study-related records will occur to evaluate 
the study conduct and compliance with the protocol, ICH GCP, and applicable regulatory 
requirements.

Data capture for this study is planned to be electronic: 
• 
All source documentation supporting entries into the eCRFs must be maintained and 
readily available. 
• 
Updates to eCRFs will be automatically documented through the software’s “audit 
trail”. 
• 
To ensure the quality of clinical data across all subjects and sites, a clinical data 
management review is performed on subject data received at Amgen.  During this 
review, subject data are checked for consistency, omissions, and any apparent 
discrepancies.  In addition, the data are reviewed for adherence to the protocol and 
GCP.  To resolve any questions arising from the clinical data management review 
process, data queries are created in the EDC system database for site resolution 
and subsequently closed by the EDC system or by an Amgen (or designee) 
reviewer. 
• 
The investigator signs only the Investigator Verification Form for this electronic data 
capture study.  This signature indicates that the investigator inspected or reviewed 
the data on the eCRF, the data queries, and the site notifications, and agrees with 
the content. 
Amgen (or designee) will perform self-evident corrections to obvious data errors in the 
clinical trial database, as documented in the Study Specific Self Evident Corrections 
Plan.  Examples of obvious data errors that may be corrected by Amgen (or designee) 
include deletion of obvious duplicate data (eg, same results sent twice with the same 
date with different visits) and clarifying “other, specify” if data are provided (eg, race, 
physical examination).  Each investigative site will be provided a list of the types of 
corrections applied to study data at the initiation of the trial and at study closeout.   
12.4 
Investigator Responsibilities for Data Collection 
The investigator is responsible for complying with the requirements for all assessments 
and data collection (including subjects not receiving protocol-required therapies) as 
stipulated in the protocol for each subject in the study.  For subjects who withdraw prior 
to completion of all protocol-required visits and are unable or unwilling to continue the 
Schedule of Assessments (Table 2), the investigator can search publically available 
records [where permitted]) to ascertain survival status.  This ensures that the data set(s) 
produced as an outcome of the study is/are as comprehensive as possible.   
12.5 
Language 
All written information and other material to be used by subjects and investigative staff 
must use vocabulary and language that are clearly understood.

Appendix D.  Modified World Health Organization (WHO) Response Criteria 
A modified version of the World Health Organization (WHO) response criteria 
(WHO handbook for reporting results of cancer treatment, 1979) will be employed in this 
study. 
Method of Measurement of Melanoma Tumor Lesions 
Clinical Examination Using Caliper:  All measurements will be determined using a 
ruler or calipers and reported in metric notation (mm) and will be recorded 
bi-dimensionally.  Clinical lesions will only be considered measurable when they are 
superficial and ≥ 10 mm in at least 2 dimensions as assessed using calipers 
(eg, superficial cutaneous melanoma lesion).  (Note:  When a lesion can be evaluated by 
both, clinical examination and imaging, radiographic imaging evaluations should be 
preferred since it is more objective).  
CT scans (or MRI):  Computed tomography (CT) scans by contrast-enhanced or spiral 
scan (or magnetic resonance imaging [MRI] scan) will be performed to evaluate tumor 
response for nodal/soft tissue disease (including lymph nodes).  Measurability of lesions 
on CT scans is based on the assumption that CT slice thickness is 5 mm or less.  When 
CT scans have slice thickness greater than 5 mm, the minimum size for a measurable 
lesion should be the greater of either at least 10 mm or twice the slice thickness.  MRI is 
acceptable to assess disease extent if used throughout the study. 
The same method of assessment and the same technique should be used to 
characterize each identified and reported lesion at baseline and during follow-up.  A 
switch from contrast enhanced CT to noncontract CT or to MRI (or vice versa) should 
not preclude response assessment if, in the judgment of the site radiologist, there is no 
significant difference in the assessment by changing modalities.  This may occur if a 
subject has developed a medical contraindication to intravenous contrast for CT scans 
while on trial.  This change would require the preapproval of the sponsor medical 
monitor. 
Positron Emission Tomography (PET)/CT Scans:  If a combined PET/CT scan is 
performed at the discretion of the investigator, the CT portion of that exam should not be 
substituted for the dedicated CT exams required by this protocol.  The PET portion of the 
CT may introduce additional data which may bias the investigator assessment of 
response if it is not routinely or serially performed.  However, if the investigator or the 
site radiologist can document that the CT performed as part of a PET/CT is of identical

CONFIDENTIAL 
 
 
diagnostic quality to a diagnostic CT (with intravenous and oral contrast) then the CT 
portion of the PET/CT can be used for tumor measurements.  
Ultrasound:  Ultrasound may be used to assess superficial palpable lymph nodes and 
subcutaneous lesions where ultrasound provides a more accurate measure than clinical 
measurement, CT or MRI.  In addition, ultrasound can be useful to confirm the complete 
disappearance of superficial lesions usually assessed by clinical examination.  However, 
if ultrasound is not useful in assessment of lesion size it must not be used as a method 
of measurement.  If new lesions are identified by ultrasound in the course of the study, 
confirmation by CT or MRI is advised. 
Measureable Disease  
Measurability is defined by the ability to measure a lesion bi-dimensionally with surface 
area determined by multiplying the longest diameter by the diameter perpendicular to the 
longest diameter as defined below.  An individual lesion measure is therefore provided 
by the product of a tumor’s longest diameter and the diameter perpendicular to that. 
All measurements will be determined using a ruler or calipers and reported in metric 
notation (mm) and will be recorded bi-dimensionally.  
Definitions of Measurable and Nonmeasurable: 
At baseline (the last assessment on or prior to the first dose of study drug being 
administered), tumor lesions will be categorized as follows:   
• 
measurable or  
• 
nonmeasurable but evaluable  
Measurable Lesions: 
Measurable lesions are defined at baseline as lesions that can be accurately and serially 
measured in at least 2 dimensions and for which the longest diameter is: 
• 
≥ 10 mm as measured by CT scan, MRI, or ultrasound for nodal/soft tissue disease 
(including lymph nodes) 
• 
≥ 10 mm caliper measurement by clinical exam for superficial cutaneous or 
subcutaneous melanoma lesion as measured by caliper 
• 
multiple superficial melanoma lesions which in aggregate have a total diameter of 
≥ 10 mm 
Nonmeasurable Lesions: 
All other lesions, including small lesions (longest diameter < 10 mm by 
CT/MRI/ultrasound for nodal/soft tissue disease [including lymph nodes] or < 10 mm 
caliper measurement by clinical exam for superficial cutaneous melanoma lesion) and

CONFIDENTIAL 
 
 
other truly nonmeasurable lesions are considered nonmeasurable and characterized as 
nonindex lesions.  This will include any measurable lesions beyond the maximum 
number of 10 lesions that were not chosen as index lesions.   
Lesions with Prior Local Treatment: 
Tumor lesions situated in a previously irradiate area, or an area subject to other 
loco-regional therapy, are usually not considered measurable unless there has been 
demonstrated progression in the lesion. 
Coalescing or splitting lesions: 
• 
Coalescing lesions:  When two or more index or new measurable lesions 
merge without distinct borders between tumors, the smaller lesion should 
have 0 x 0 mm recorded for the current and all future assessments with a 
comment indicating that the lesion coalesced with the specified lesion, and the 
larger lesion should have the size of the merged lesion recorded for the 
current assessment with a comment indicating that the lesion coalesced with 
the specified lesion and be followed for future assessments.  When two or 
more nonindex or new non-measurable lesions merge, the smaller lesion 
should be recorded as absent for the current and all future assessments, and 
the larger lesion should be recorded as present for the current assessment 
(with a comment indicating that the lesion coalesced with the specified lesion) 
and followed for future assessments.  If an index or new measurable lesion 
and a non-index or new non-measurable lesion merge, the non-index or new 
non-measurable lesion should be absent for the current and all future 
assessments while the index lesion or new measurable lesion should include 
both merged lesions for recording measurements with a comment indicating 
that the lesion coalesced with the specified lesion. 
• 
Splitting lesions:  When an index or new measurable lesion splits into two or 
more lesions the largest measurable part of the split lesion should be 
considered to be the previously recorded index or new measurable lesion with 
measurements provided for the current assessment with the comment 
indicating that the lesion split from the specified lesion, and followed for future 
assessments. The remaining lesions would be reported as a new measurable 
lesions or new non-measurable lesions depending on measurability with a 
comment indicating that the lesion split from the specified lesion. In this case, 
appearance of a new lesion from a previous lesion will not be considered a 
disease progression solely due to appearance of a new lesion (may be 
considered a disease progression due to > 25% increase in the sum of the 
products of the perpendicular diameters of all index tumors since baseline, or 
the unequivocal appearance of a new tumor, other than the product of the split 
tumor, since the last response assessment time point). 
Measureable Tumor Assessment/Burden: 
Baseline Documentation of “Index Lesions”: 
All baseline evaluations should be performed as close as possible to enrollment and 
never more than 4 weeks (ie, 28 days) prior to enrollment.

Protocol Number:  20120325

At baseline, up to 10 measurable cutaneous, nodal, or soft tissue lesions will be chosen 
to measure over the course of therapy.  The distribution of these index lesions should be 
representative of the subject’s overall disease status.  Index lesions should be selected 
on the basis of their size (lesions with longest bi-dimensionally perpendicular diameters) 
and suitability for accurate repeated measurements by imaging techniques (CT, MRI or 
ultrasound) and/or other method such as clinical exam. 
The sum of the products of the two largest of perpendicular diameters (SPD) of all index 
lesions will be calculated and reported. 
If subject has multiple small superficial melanoma lesions at baseline (less than 
10 mm in longest diameter) which  in aggregate have a total diameter of ≥ 10 mm, 
up to 10 largest lesions that were included in this measurement will be reported as 
”Index Lesions”, and sum of the products of the two largest of perpendicular SPD 
of these lesions will be calculated and reported for tumor response assessments.  
Baseline Documentation of “Nonindex Lesions”:   
All other lesions (or sites of disease), including any measurable lesions that were not 
chosen as index lesions will be identified as nonindex lesions.  Nonindex lesions should 
be recorded and assessed qualitatively over the course of therapy. 
Follow-up “Index Lesions”: 
At each subsequent tumor assessment, the SPD of the index lesions are added together 
to provide the total tumor burden. 
Follow-up “Nonindex Lesions”: 
Nonindex disease measurements are not required and these lesions should be followed 
as “present,” “absent,” or in rare cases “unequivocal progression”. 
Response Criteria 
Evaluation of Objective Response: 
The subject response will be assessed based on the response of the index lesions and 
nonindex lesion, and presence or absence of new lesions.  Confirmation of complete or 
partial response is not required.  The overall response is derived from time point 
response assessments as described in Table 5, Table 6, and Table 7.

Table 5.  Definition of Index Lesion Tumor Response Including New Lesions 
Complete Response (CR): 
Complete disappearance of all index lesions, including any new 
tumors which might have appeared.  Any residual cutaneous or 
subcutaneous index lesions must be documented by 
representative biopsy to not contain viable tumor. 
Partial Response (PR): 
Achieving a 50% or greater reduction in the SPD of the 
perpendicular diameters of all index lesions at the time of 
assessment as compared to the sum of the products of the 
perpendicular diameters of all index lesions at baseline.  If any 
new lesions have appeared, the sum of products of the 
perpendicular diameters of new measurable lesions must have 
reduced by 50% or more from when first documented.   
Disease Progression (PD): 
A > 25% increase in the sum of the products of the perpendicular 
diameters of all index tumors since baseline, or the unequivocal 
appearance of a new tumor since the last response assessment 
time point.  
There are 2 types of PD defined in this protocol: 
Non-clinically relevant disease progression (PDn):  PD in 
subjects who do not suffer a decline in performance status and/or 
in the opinion of the investigator do not require alternative therapy.  
Subjects showing overall response as PDn will be allowed to 
continue study treatment.  
Clinically relevant disease progression (PDr):  PD that is 
associated with a decline in performance status and/or in the 
opinion of the investigator the subject requires alternative therapy.  
Subjects with PDr will be allowed to remain on study until 
24 weeks of therapy unless, in the opinion of the investigator, other 
treatment is warranted.  
Stable Disease (SD): 
Neither sufficient tumor shrinkage of index lesion to qualify for 
response (PR or CR) nor sufficient tumor increase of index lesion 
to qualify for PD. 
Unable to Evaluate (UE): 
Any index lesion present at baseline which was not assessed or 
was unable to be evaluated leading to an inability to determine the 
status of that particular tumor for that time point. 
Not Done (ND) 
Radiographic image or clinical measurement were not performed 
at this time point to evaluate the index lesions

opinion of the investigator the subject requires alternative therapy.  
Subjects with PDr will be allowed to remain on study until 
24 weeks of therapy unless, in the opinion of the investigator, 
other treatment is warranted. 
Unable to Evaluate (UE): 
Any nonindex lesion present at baseline which was not assessed 
or was unable to be evaluated leading to an inability to determine 
the status of that particular tumor for that time point.

Amendment 1 Date: 
31 August 2015 
Superseding Date: 
21 September 2015 
This document summarizes the changes made to the protocol in both Amendment 1 and 
the superseding version. 
Rationale: 
 
Removed Inclusion Criterion 105 to allow subjects to join the study after having 
received first-line therapy. 
 
Removed exclusion of subjects receiving any non-oncology vaccine therapies used 
for the prevention of infectious disease within 28 days prior to enrollment and during 
treatment period (Exclusion criterion 210). 
 
Clarified that if no viable cells were found following surgery, the response definition 
will be complete response (CR). 
 
Added testing for herpes simplex virus type 2 (HSV-2) within 3 days prior to dose at 
day 1 of week 1 [Cycle 1], week 6 [Cycle 3], and week 12 [Cycle 6]. 
 
Increased the window to 5 days for tumor biopsy for biomarker analysis for the 
Week 1 biopsy, 7 days for the Week 6 biopsy, and to 7 days after documentation of 
disease progression at PD. 
 
Added assessment of Eastern Cooperative Oncology Group (ECOG) performance 
status every 3 months during treatment period. 
 
Revised photography assessments in the schedule of assessments to remove 
requirement at screening, update cycles, and removed the word “measurable.” 
 
In Schedule of Assessments, clarified that the week 1 biopsy should not be collected 
prior to the subject being enrolled. 
 
Removed word “uninjected” from the correlation between changes in intratumoral 
CD8+ cell density during treatment and objective response rate in the study 
endpoints. 
 
Revised the number of planned sites to be 50. 
 
Added exclusion criterion to avoid potential viral transmission during sexual contact. 
 
Specified how lesions that separate or merging are to be assessed.

• 
Added an interim analysis. 
• 
Added reporting of treatment related adverse events during the long-term follow-up. 
• 
Added addition of anti-cancer therapy for melanoma during long term period 
follow-up. 
• 
In Table 5: Definition of Index Lesion Tumor Response Including New Lesions, 
removed the following text from the definition of partial response, “Any residual 
cutaneous or subcutaneous index or new lesions that must be tumor free for the 
subject to meet the criteria for partial response (PR) must be documented as such by 
representative biopsy”.  
• 
Updated text throughout document to specify cycle number corresponding to study 
week. 
• 
Implemented minor administrative and formatting changes. 
• 
Added references in Section 2.2 and in the reference list. 
• 
Added ECOG and physical examination during treatment period and follow-up 
period. 
• 
Defined the final analysis after 24 months from LSE rather than keeping it open 
ended. 
• 
Clarified that unless patient dies or withdraws full consent after they have completed 
the LTFU portion of the study they will then be transferred to the registry protocol 
where they will continue to be followed up, until death or full consent withdraw.

Primary analysis of the OPTiM Study showed a statistically significant difference 
between the rate of durable response among subjects treated with talimogene 
laherparepvec (16%; 95% CI:  12%, 21%) versus those treated with GM-CSF (2%; 95% 
CI:  0%, 5%) (p-value < 0.0001).  A trend toward improved OS was also seen in a 
preplanned interim analysis (HR 0.79; 95% CI:  0.61, 1.02; p-value = 0.07) 
(Andtbacka et al, 2013).  Survival at 12, 24, and 36 months in the talimogene 
laherparepvec arm was estimated to be 74%, 50%, and 41%, respectively, and 69%, 
41%, and 28% in the GM-CSF arm, respectively.  The most common side effects were 
fatigue, chills, and pyrexia.  Serious adverse events occurred in 26% of the talimogene 
laherparepvec subjects and 13% of the GM-CSF subjects.  No grade 3/4 adverse events 
occurred in ≥ 3% of subjects in either arm.

6% with GM-CSF to 26% with talimogene laherparepvec (P < 0.0001, descriptive).  
Similarly, 11% of patients had a CR in the talimogene laherparepvec arm versus 
< 1% in the GM-CSF arm.  In the event-driven primary OS analysis (secondary end 
point), median OS with talimogene laherparepvec treatment was 23.3 months 
compared with 18.9 months with GM-CSF treatment (HR, 0.79 [95% CI, 0.62‒1.00]; 
P=0.051) (Andtbacka et al, 2015).  At the final planned analysis of OS which 
happened when last enrolled subject completed 3 years of follow-up, median OS 
was 23.3 months in the talimogene laherparepvec arm and 18.9 months in the

”Index Lesions”, and sum of the products of the two largest of perpendicular SPD 
of these lesions will be calculated and reported for tumor response assessments.

Partial Response (PR): 
Achieving a 50% or greater reduction in the SPD of the perpendicular 
diameters of all index lesions at the time of assessment as compared 
to the sum of the products of the perpendicular diameters of all index 
lesions at baseline. If any new lesions have appeared, the sum of 
products of the perpendicular diameters of new measurable lesions 
must have reduced by 50% or more from when first documented. Any 
residual cutaneous or subcutaneous index or new lesions that must 
be tumor free for the subject to meet the criteria for PR must be 
documented as such by representative biopsy.
