PROTOCOL SUMMARY 
1.1 SYNOPSIS  
Title: 
A phase II study of talimogene laherparepvec (T-VEC) in the treatment of 
recurrent cutaneous angiosarcoma 
Study Description: 
Seventy-five percent of cutaneous angiosarcoma (CA) patients will eventually fail 
systemic therapy, and relapsed/refractory patients are left with no known 
efficacious treatment options. We hypothesize that direct treatment of CA lesions 
with T-VEC will stimulate local antitumor response, leading to objective responses 
and prevention of recurrence among enough patients to make this a viable 
treatment option for the affected population.  
Objectives: 
 
 
Primary Objective: To evaluate the efficacy of T-VEC as treatment for 
relapsed/refractory cutaneous angiosarcoma 
 
Secondary Objectives: 
1. To establish duration of response among treated patients that demonstrate 
response 
2. To measure the duration of progression-free survival among treated patients 
3. To measure the complete response rate for lesions that have complete clinical 
regression following study treatment 
4. To monitor adverse events following administration of T-VEC injections 
5. To measure the rate of patients requiring surgical resection of T-VEC–treated 
lesions 
 
Tertiary/Exploratory Objectives: 
1. To measure the degree of immune infiltration in surgically resected T-VEC–
treated tumors 
2. To evaluate surgical outcomes for those patients whose T-VEC–treated tumors 
are resected 
Endpoints: 
 
 
Primary Endpoint: Overall response rate: the proportion of patients to 
demonstrate complete or partial responses in injected lesions per modified 
RECIST criteria appropriate for cutaneous neoplasms. 
 
Secondary Endpoints: 
1. Response duration will be measured from the time of initial partial response or 
complete response until documented progression

2. Progression-free survival: period from time of first injection to progression of 
disease or appearance of new cutaneous angiosarcoma tumors that were not 
present at the time of study entry 
3. Complete Response rate: proportion of patients with CR, defined as lesions with 
complete clinical regression 
4. Incidence of adverse events from injection of T-VEC into cutaneous 
angiosarcoma  
5. Proportion of patients whose T-VEC–treated tumors require surgical resection 
 
Tertiary/Exploratory Endpoints: 
1. Immunohistochemistry and flow cytometry analyses of immune infiltration 
within resected tumor specimens 
2. Surgical outcomes recorded will include margin status, percent viable tumor, 
postoperative complications, and disease-free interval following resection. 
Study Population: 
Thirteen patients with locally advanced recurrent or unresectable cutaneous 
angiosarcoma 
Phase: 
Phase II 
Description of 
Sites/Facilities Enrolling 
Participants: 
Moffitt Cancer Center (Tampa, FL), a high-volume, NIH-designated Comprehensive 
Cancer Center  
Description of Study 
Intervention: 
Patients will undergo intralesional injections of up to 4 cc of 106 plaque-forming 
units (PFU)/mL of T-VEC. Dose is dependent on the diameter of the lesions to be 
injected (volume injected is related to diameter of lesion(s) at time point 0). Three 
weeks later and every other week thereafter, the patients will be injected with up 
to 4 cc of 108 PFU/mL, with dose dependent on the diameter of the lesion(s) to be 
injected. Patients may be treated for up to 12 months. 
A Simon's 2-stage design will be used, assuming that at least a P0 response rate of 
10% will be reached for injected lesions. In the first stage, 8 patients will be 
accrued. If there is > 1 response in these 8 patients, the study will enroll 5 
additional patients for a total of 13. The null hypothesis will be rejected if 4 or 
more responses are observed in 13 patients. This design yields a type I error rate 
of 0.03 and power of 0.8 when the P1 response rate is 40%. 
Study Duration: 
The duration of the study, defined as interval from when the study opens to 
enrollment until completion of data analyses, will be 24 months. 
Participant Duration: 
12 months

INTRODUCTION 
 
2.1 STUDY RATIONALE  
Talimogene laherparepvec (T-VEC) is an herpes simplex virus type 1- (HSV-1–) based oncolytic virus designed to 
selectively replicate in tumors and produce granulocyte macrophage colony-stimulating factor (GM-CSF) to 
stimulate antitumor immune responses. T-VEC is administered by intratumoral injection and is currently under 
investigation as intralesional therapy for several solid tumor types. Intratumoral injection of T-VEC could result in 
an influx of infiltrating T cells mediated by direct tumor destruction, potentially initiating an immune response 
against tumor-associated antigens. 
Cutaneous angiosarcoma (CA) is a difficult disease to treat, primarily due to the high recurrence rate and need for 
wide resection. CA is often associated with a prior history of radiation therapy and can respond well to taxane-
based systemic therapy, which has been used effectively in the neoadjuvant setting. Unfortunately, recurrence is 
experienced by up to 75% of patients, including those treated with combination therapy, and they have no 
efficacious second-line treatment options available to them. The use of an intralesional immunomodulatory agent 
like T-VEC represents a novel approach for the treatment of patients whose disease is not controlled by standard 
therapy and have no other options. An early report of safety using T-VEC in advanced sarcoma patients was 
presented at ASCO 2018. Three CA patients were enrolled and 2 were classified as responders. The purpose of this 
trial is to validate this early response signal in a formal phase 2 trial for CA patients. 
The goal of injecting T-VEC directly into the tumor is to stimulate both systemic and local anti-tumor responses. 
The insertion of a GM-CSF gene into the viral genome, as described in Section 2.2.2, will ideally create an adaptive 
immune response within the tumor, augmenting treatment and furthering the pathway to a complete response of 
the tumor and hopefully prevention of recurrence of cutaneous angiosarcoma. 
 
2.2 BACKGROUND  
2.2.1 DISEASE BACKGROUND 
CA is a rare cutaneous neoplasm that is classified as a soft tissue sarcoma which arises within the epidermis or 
dermis. The disease presents largely as 2 separate phenotypes. In one form, the cause is idiopathic and effects 
elderly men with a predilection for occurrence in the head and neck region. In another form, the disease is 
associated with a history of radiation therapy and most commonly affects women, with disease occurring in the 
skin of the breast after breast conservation therapy for primary breast cancer. The latter form occurs with a 
median latency period of 7 years between the exposure to radiation and development of a secondary malignancy. 
Treatment for either condition is primarily wide surgical resection. Wide margins can be difficult to obtain as 
anatomic constraints often limit the resection. Even when primary resection is feasible, recurrence is common, 
with a local recurrence rate up to 60% for those with idiopathic cutaneous angiosarcoma and 75% for those with 
radiation-associated cutaneous angiosarcoma. Complicating treatment further is the presence of multifocal 
disease in both the primary and recurrent setting, which is difficult to manage with surgical resection. Despite the 
known association, radiation therapy has been advocated for cutaneous angiosarcoma as a way to increase local 
control.

With high local recurrence rates, there is an unmet need for local therapy. The anatomic constraints limiting 
resection in the primary setting are worse with recurrence and repeat radiation therapy to a site is generally not 
feasible. Systemic therapy is used for these patients; however, these options are often restricted by the limitations 
associated with the age of these often elderly patients. 
2.2.2 STUDY AGENT 
 
T-VEC (Imlygic), previously known as OncoVexGM-CSF, is a HSV-1–derived oncolytic immunotherapy that 
selectively replicates within tumors and produces GM-CSF. In talimogene laherparepvec, HSV-1 is modified 
through deletion of 2 nonessential viral genes, ICP47 and ICP34.5. The deletion of the ICP47 gene up-regulates the 
HSV US11 gene, reduces the suppression of antigen presentation, and enables the virus to grow and replicate 
within tumor cells. Functional deletion of ICP34.5 reduces neurotoxicity and enhances tumor-selective replication. 
The gene encoding GM-CSF is inserted, and its expression promotes dendritic cell activity and increased tumor 
antigen presentation, potentially inducing greater tumor-specific T cell responses (Figure 1)  
 
 
 
T-VEC is administered by direct injection into tumors. For the indications currently FDA-approved in melanoma, an 
optimized dosing regimen consisting of a first dose of 106 plaque-forming units (PFU)/mL (total injected volume 
dependent on injectable tumor diameter) followed by subsequent doses of 108 PFU/mL (total injected volume 
dependent on injectable tumor diameter) is used. This regimen is based on a phase 1 dose-ranging study (001/01) 
in which this regimen was identified as being well tolerated by both HSV-1 seronegative and seropositive patients. 
It is anticipated that this regimen will be used in most other oncology indications going forward, including T-VEC in 
combination with other treatment modalities. 
T-VEC is a modified version of HSV-1. HSV-1 has several advantages over other viruses for development as an 
oncolytic agent. It infects a wide variety of cell types, has a rapid replication cycle resulting in cell lysis, allows the 
incorporation of single or multiple inserted genes, which may improve the anti-tumor effect, and appropriate titers 
can be produced in quantities sufficient for clinical use. 
Figure 1. Local and systemic effects of T-VEC.

Nonclinical and clinical data have shown that selective deletion of HSV genes results in a nonpathogenic virus with 
promising properties for cancer therapy. The modifications resulting in the enhanced properties of T-VEC include 
the following: 
 
Use of a new isolate of HSV-1 (strain JS1), demonstrated to more effectively lyse a variety of 
human tumor cell lines in vitro than other viruses used in previous clinical studies.  
 
Functional deletion of the HSV-1 gene encoding ICP47, improving the presentation of tumor 
antigens following oncolytic virus replication and intended to enhance the anti-tumor 
immune response.  
 
Insertion of the gene encoding human GM-CSF, thereby inducing the differentiation and 
proliferation of dendritic cell precursors in and around the injected tumor and intended to 
aid the induction of a systemic anti-tumor immune response. 
Multiple safety features have also been incorporated into talimogene laherparepvec, including 
 
Functional deletion of ICP34.5, which functions as a virulence factor during HSV infection. 
This functional deletion limits replication in non-dividing cells and renders the virus non-
pathogenic. The safety of ICP34.5 functionally deleted HSV has been shown in multiple 
clinical studies.  
 
Insertion of the human GM-CSF coding sequence such that it replaces all of the gene 
encoding ICP34.5 to ensure that any potential recombination events between T-VEC and 
wild-type virus could only result in a disabled, non-pathogenic virus and could not result in 
the generation of wild-type virus carrying the gene for human GM-CSF. 
 
The HSV thymidine kinase (TK) gene remains intact, which renders T-VEC sensitive to anti-
viral agents such as acyclovir. Therefore, acyclovir could be used to block virus replication, if 
necessary, although this has never been found to be needed in the patients treated to date. 
T-VEC has been tested for efficacy in a variety of in vitro (cell line) and in vivo murine tumor models and has been 
shown to eradicate tumors or substantially inhibit their growth at doses comparable to those used in clinical 
studies. Nonclinical evaluation has also confirmed that GM-CSF enhances the immune response generated, 
enhancing both injected and uninjected tumor responses, and that increased surface levels of MHC class I 
molecules result from the deletion of ICP47.

talimogene laherparpvec monotherapy versus GM-CSF were chills (49% versus 9%), pyrexia (43% versus 9%), 
injection-site pain (28% versus 6%), nausea (36% versus 20%), influenza-like illness (30% versus 15%), and fatigue 
(50% versus 36%). Adverse events (AE) of grade 3 or greater occurred in 36% of patients receiving T-VEC and 21% 
of subjects receiving GM-CSF. The only grade 3/4 adverse events occurring in ≥ 5 subjects was cellulitis (6 patients 
[2.1%] treated with T-VEC; 1 patients [< 1%] treated with GM-CSF). Of 10 fatal adverse events in the T-VEC arm, 8

were attributable to disease progression. The remaining two fatal adverse events (sepsis in the setting of 
salmonella infection; myocardial infarction) were not considered treatment-related per investigator. 
Overall with T-EC, 86% of AEs were grade 1 or 2, although at least one grade 3 or 4 AE was observed in each 
patient. The investigators considered just two adverse events (pyrexia and fatigue) to be T-VEC-related and 
occurred in two or more patients. Across all cohorts and severity grades, the most frequent AEs were consistent 
with chemoradiation delivery. The grade 3 or 4 AEs observed in ≥ 2 patients were unrelated to T-VEC. The AE 
profile, therefore, may include events related to T-VEC, chemotherapy, radiation, tumor-related signs and 
symptoms, disease progression, and/or a combination of these. However, the concurrent use of T-VEC, cisplatin, 
and external beam radiation therapy has not resulted in more frequent or more severe adverse events beyond 
those typically encountered with these other anti-cancer therapies. 
After intratumoral injection, T-VEC is generally cleared from blood and urine of patients within 48 hours. However 
it can be detected for up to 1 week in the blood of 30% of patients and in the urine of 20% of patients. Low levels 
of virus have been detected on the surface of injected lesions for up to 2 weeks in 11% of patients. In most cases, 
this was observed in seronegative patients in the phase 1 study, in which a higher first dose of T-VEC was 
administered than has been used in subsequent studies. Subsequent studies have therefore used a lower initial 
dose. 
No cases of confirmed infection of non-tumor tissue by T-VEC in treated patients have been reported to date. In 
the pivotal clinical study, AEs related to HSV infections were reported in 5.5% of patients (n = 16) in the T-VEC 
group and 1.6% (n = 2) in the GM-CSF group. Most cases (n = 14) were reported as oral herpes, with 1 case each 
reported as herpes simplex and herpetic keratitis in the T-VEC group. The patient with herpetic keratitis had a 
history of this event prior to enrollment in the study. Whether the reported lesions were due to wild-type herpes 
or to T-VEC could not be confirmed as viral testing was not performed.(Andtbacka, Kaufman et al. 2015) T-VEC is 
now Food and Drug Administration approved in the United States as Imlygic for melanoma, and the prescribing 
insert can be found at http://pi.amgen.com/~/media/amgen/repositorysites/pi-amgen-com/imlygic/imlygic_pi. 
2.3.1.2 KNOWN POTENTIAL RISKS FOR T-VEC 
Please see T-VEC Investigator’s Brochure (IB) for full information and complete listing on important potential risks.   
Summary of identified risks are included below. 
Identified Risk: Injection Site Reactions 
Because T-VEC is administered by direct injection into cutaneous, subcutaneous, and nodal tumor masses, 
injection site AEs may occur, such as erythema, local skin discoloration, induration, warmth, and pain. Infrequently, 
injected cutaneous tumor masses may undergo necrosis, predisposing patients to local and/or systemic infections. 
Similarly, injected pathologic lymph nodes may enlarge or become necrotic. Uncommonly, necrotic lymph nodes 
may be the site of persistent drainage that requires corrective measures. In clinical studies, adverse events of 
“injection site pain” and “injection site reaction” were very common, occurring in ≥ 10% of T-VEC-treated subjects. 
Most events of injection site pain and injection site reaction in patients receiving T-VEC were mild to moderate in 
severity. Subjects seronegative at baseline for HSV-1, when given an initial dose of T-VEC at a concentration of 106 
PFU/mL, do not appear to experience more exaggerated injection site reactions than those who are seropositive at 
baseline.  
Important Identified Risk: Cellulitis at Site of Injection 

T-VEC for cutaneous angiosarcoma – 
v0.4 Sept 2019 
Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
10 
Intralesional administration of T-VEC by injection has been associated with cellulitis at the injection site. In some 
cases, a local inflammatory reaction with localized tumor necrosis developed; in other cases, a bacterial infection 
developed. In the pivotal clinical study, the incidence of adverse events in the bacterial cellulitis category was 6.2% 
(n = 18) in the T-VEC group and 1.6% (n = 2) in the GM-CSF group. Seven patients (2.4%) in the T-VEC group and 1 
patient (0.8%) in the GM-CSF group experienced serious adverse events (SAEs) of cellulitis. Five of the events (all in 
the T-VEC arm) were considered to be possibly related to study treatment. Fever, elevated white blood cell count, 
bacteremia or sepsis, and hospitalization for intravenous antibiotics were reported in 5 of the 7 cases in the T-VEC 
group. 
Important Identified Risk: Accidental Exposure of Health Care Providers to T-VEC 
A needle stick injury, spill, or splash-back during administration may result in accidental exposure of health care 
providers to T-VEC. The ICP34.5 gene deletion is intended to allow only tumor-selective replication and limited or 
no viral replication in normal tissues. However, T-VEC injection can result in signs or symptoms of primary infection 
at the site of exposure. In the event of an accidental exposure to T-VEC, exposed individuals should be advised to 
clean affected area thoroughly with soap and water and/or a disinfectant. If signs or symptoms of herpetic 
infection develop, patients should contact their healthcare provider who will call Amgen Medical Information and ( 
1-855-IMLYGIC or 1-855-465-9442).   Healthcare providers with direct exposure (needle stick, back splash) or  
signs/symptoms of herpetic infection will call Amgen Medical Information directly on their own behalf. T-VEC is 
sensitive to acyclovir. Amgen must be notified and swabs taken of all suspected herpetic outbreaks. 
Important Identified Risk: Disseminated Herpetic Infection in Severely Immunocompromised Individuals 
Patients with immunosuppression for any reason were excluded from clinical trials with T-VEC. Disseminated 
herpetic infection in severely immunocompromised individuals is defined as an important identified risk based on 
the following the nonclinical data and literature. Evidence of lethal systemic viral infection was observed in 100% 
of severe combined immunodeficiency (SCID) mice (deficient in T and B cells) following intratumoral injection of T-
VEC in a mouse colon carcinoma xenograft model. Similar findings were observed in up to 20% of BALB/c nude 
mice (primarily deficient in T-cell function) following intratumoral injection of T-VEC in Ewing sarcoma and 
osteosarcoma xenograft models. Viral inclusion bodies and/or necrosis in enteric neurons in the gastrointestinal 
tract, adrenal gland, and skin were observed in both mouse strains; and in pancreatic islet cells, eye, pineal gland, 
and brain of SCID mice. Lethality in 100% of animals following intracutaneous injection of wild-type HSV-1 in nude 
mice has been reported (Hayashida et al, 1982; Yamamoto et al, 1985). The data in T-VEC-treated SCID mice 
indicated that severe toxicity associated with disseminated viral infection may occur in patients who are severely 
immunosuppressed. The data in the BALB/c nude mice suggested the potential for toxicity due to T-VEC in patients 
with less severe immunosuppression. Consistent with the general literature, these data indicate an important role 
of host defenses, including T and B cells, in the immune response to T-VEC and HSV-1 viruses. 
 
2.3.2 KNOWN POTENTIAL BENEFITS  
Please see T-VEC Investigator’s Brochure (IB) for full information and complete listing on the clinical efficacy of T-
VEC in various tumor types.   Summary of efficacy data is included below. 
The benefits of T-VEC have been described in five studies when used as monotherapy and another four studies 
when used in combination therapy for various tumor types.  The most extensive experience has been in patients 
with cutaneous melanoma where overall response rates (ORR) have been reported between 26-28% when used as 
monotherapy and 50-57% when combined with immune checkpoint inhibitors.   The only study report survival

v0.4 Sept 2019 
Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
11 
data indicated an increase in overall survival in patients that received T-VEC compared to control subjects that 
received intralesional GM-CSF (23.3 months vs. 18.9 months, p=0.51).    
 
In reports of T-VEC in other solid tumors, data exists for those with head and neck squamous cell carcinoma.  In 
these patients, the clinical response rate (defined as decrease in size from screening) was 94.6% and the pathologic 
CR rate for those that underwent resection was 93.3%.    
 
A recent presentation at the American Society of Clinical Oncology meeting in 2018 described the safety and 
efficacy of T-VEC in combination with pembrolizumab in patients with a variety of soft tissue sarcoma histologic 
subtypes.   In this report, 3 patients with cutaneous angiosarcoma were treated, two of whom demonstrated a 
partial response.   While no patients in the study exhibited complete response, there was an overall response rate 
of 75% for patients with locally advanced disease.   The median time to response was 16 weeks (range 8-32 
weeks). 
 
For a full list of potential benefits, please refer to the investigator brochure.  
 
2.3.3 ASSESSMENT OF POTENTIAL RISKS AND BENEFITS  
 
The efficacy of T-VEC in various solid tumor types has been demonstrated in several clinical trials.  As an 
intralesional therapy, this treatment is most promising for patients with locally advanced disease.  The primary 
risks associated with this treatment are injection site reactions and cellulitis surrounding the injection site.   These 
risks are low and expected given the mechanism of action for this therapy.  Most of the injection site reactions 
could be described as a positive indication of an immune-stimulation.   Specific risks to this treatment include the 
potential for infection of healthcare providers or patients due to exposure.   Using universal precautions for the 
injection procedure mitigates this risk to the greatest degree and treatment with acyclovir is available for these 
rare instances. 
The potential benefits for patients with locally advanced cutaneous malignancies outweigh the reported risks.   
Given the paucity of treatment options for those that have relapsed or recurred with standard treatment, reported 
response rates of nearly 30% for monotherapy and up to 75% with combination therapy are encouraging.   The 
highest rates of response were seen in the most recent presentation for patients with soft tissue sarcoma where 
75% of patients with locally advanced disease experienced and objective response, the vast majority of which were 
ongoing.   The safety profile in this report was quite acceptable with only 1 reported grade 3/4 fever related to T-
VEC.   There were no reported instances of cellulitis in this study and no mention of injection site reactions. 
Taken together, the potential for benefit in these patients outweighs the reported risks from several prior, large 
clinical trials.  The significant experience with this treatment at this institution further supports the safety of 
administering this treatment.   One might argue that the response rates for patients with soft tissue sarcoma may 
well be due to combination therapy with anti-PD1 therapy, but the results of the SARC-028 clinical trial would 
suggest otherwise.  That trial reported a 10% overall response rate for patients that received anti-PD1 
monotherapy for advanced soft tissue sarcoma.   While there is no current available data for T-VEC monotherapy 
in patients with soft tissue sarcoma, the SARC-028 data suggests that the contribution of T-VEC to this response 
rate is significant.   The design of this trial has thus assumed a response rate of 40% for cutaneous angiosarcoma 
patients given the monotherapy treatment plan.

STUDY DESIGN  
 
4.1 OVERALL DESIGN 
 
This is a single-center, single-arm, phase 2 study to evaluate the efficacy of intratumoral injection with talimogene 
laherparepvec (T-VEC) as monotherapy in relapsed/refractory locally advanced cutaneous angiosarcoma (CA) 
tumors.   The hypothesis is that intralesional therapy using T-VEC will result in an objective response (CR or PR) 
these patients.   There will be no dose modifications from the current FDA-approved dose for other indications.  
Specific details regarding dosing and administration can be found in section 6.1.2.   There are no stratifications in 
this trial. 
 
Patient enrollment will follow a Simon's 2-stage design, assuming that at least a P0 response rate of 10% will be 
reached for injected lesions. In the first stage, 8 patients will be accrued. If there is > 1 response in these 8 
patients, the study will enroll 5 additional patients for a total of 13. The null hypothesis will be rejected if 4 or more 
responses are observed in 13 patients. This design yields a type I error rate of 0.03 and power of 0.8 when the P1 
response rate is 40%.    
 
4.2 SCIENTIFIC RATIONALE FOR STUDY DESIGN 
There are several considerations regarding this study design: 
 
1. Dosing 
a. The study drug is currently FDA-approved for cutaneous melanoma with a dosing schedule 
proven to be safe and effective in several prior clinical trials.   We have chosen to use this dose 
given the proven safety profile and the efficacy shown in a prior phase 2 study of patients with 
soft tissue sarcoma. 
2. Phase 2 
a. The phase 2 design is based on the previously reported data, demonstrating safety with 
intralesional therapy for locally advanced soft tissue sarcoma patients.   A phase 1 design would 
be duplicitous to this data presented at ASCO 2018 (Kelly, Bowler, et. al) 
3. Patient population 
a. Patient with locally advanced cutaneous angiosarcoma have very limited options for treatment.  
We have limited this trial to locally advanced patients, since the efficacy of control for distant 
disease (stage IV) has not been demonstrated to nearly the same degree as for patients with 
locally advanced disease.   Gaining control of local disease will yield tremendous benefit for 
patients with otherwise no treatment options. 
4. Response rate 
a. The P1 response rate (40%) is based on prior published response data for similar patients (ORR 
75%) when T-VEC was used in combination with checkpoint inhibition.   Given that checkpoint 
inhibitors have very limited efficacy when used alone in patients with sarcoma, the P1 response 
rate was chosen as it is 10% higher than the reported efficacy for cutaneous melanoma.

5.4 SCREEN FAILURES 
 
Screen failures are defined as participants who consent to participate in the clinical trial but do subsequently 
receive the study intervention or entered in the study. A minimal set of screen failure information is required to 
ensure transparent reporting of screen failure participants, to meet the Consolidated Standards of Reporting Trials 
(CONSORT) publishing requirements and to respond to queries from regulatory authorities. Minimal information 
includes demography, screen failure details, eligibility criteria, and any serious adverse event (SAE). 
 
Individuals who do not meet the criteria for participation in this trial (screen failure) because of a poor 
performance status may be rescreened. Rescreened participants should be assigned the same participant number 
as for the initial screening. 
 
5.5 STRATEGIES FOR RECRUITMENT AND RETENTION 
 
Both men and women and members of all races and ethnic groups are eligible for this trial.   It is anticipated that 
one patient per month will be accrued.  The source of patients will be from the outpatient clinics and general 
public.   The study will be advertised through patient advocacy groups, social media, and flyers in the clinic to 
increase participation.   Given the participation over one year, we will use multiple methods to contact patients 
including phone, email, and EHR patient portal to ensure continued participation.

6.1 STUDY INTERVENTION(S) ADMINISTRATION 
 
6.1.1 STUDY INTERVENTION DESCRIPTION 
 
This trial will use talimogene laherparepvec (T-VEC) as monotherapy for the treatment of locally advanced, 
relapsed/refractory cutaneous angiosarcoma.  Full details regarding this drug are included in the Investigator 
Brochure and pharmacy insert (http://pi.amgen.com/~/media/amgen/repositorysites/pi-amgen-
com/imlygic/imlygic_pi).  Treatment will be administered on an outpatient basis. Reported adverse events and 
potential risks for T-VEC are described in Section 2.3. Appropriate dose modifications for T-VEC are described in 
Section 6.1.2.3. No investigational or commercial agents or therapies other than those described below may be 
administered with the intent to treat the patient's malignancy. Standard supportive care medications are allowed. 
6.1.2 DOSING AND ADMINISTRATION 
6.1.2.1 T-VEC TREATMENT PLAN 
The first and second injections of T-VEC will be injected into the tumor 3 weeks apart (+3 days) to allow for 
seroconversion, and then the remaining injections will be given every 2 weeks (+/- 3 days) directly into the primary 
tumor only, for up to 1 year of injections. 
The 106 PFU/mL dose will be used for the initial injection (up to 4 mL total volume), while all subsequent injections 
will be done with 108 PFU/mL (up to 4 mL total volume). 
6.1.2.2 DOSING AND ADMINISTRATION OF T-VEC 
The total volume of T-VEC to be prepared will be based on investigator evaluation of injectable lesions and 
estimation of the total volume needed based on the T-VEC injection volume guideline based on tumor size table 
(see below). 
The maximum volume of T-VEC administered at any dose is 4.0 mL for any individual lesion. The maximum dose in 
any one treatment is 4.0 mL. Use the maximum amount whenever lesions allow.  
The recommended volume of T-VEC to be injected into the tumor is dependent on the size of the tumor on 
ultrasonography on the day of injection and should be determined according to the injection volume guideline in 
the following table: 
T-VEC Injection Volume Guideline Based on Tumor Size

Administration of T-VEC will follow the specific guidelines and procedure outlined in the Pharmacy Information 
Guide. 
6.1.2.3 DOSING DELAYS/DOSE MODIFICATIONS 
If talimogene laherparepvec treatment was delayed by > 2 weeks, that dose will be deemed to have been missed 
and the subject will proceed to the next scheduled treatment visit. Dose reductions of talimogene laherparepvec 
are not permitted, other than 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 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. 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). 
 
If talimogene laherparepvec dosing is delayed by more than 4 weeks from the date of the planned dose (ie, 
approximately 6 weeks or 7 weeks depending whether the patient is receiving Q2W or Q3W dosing 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.  
 
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. In this case, discontinuation from the treatment occurs immediately upon 
introduction of the new agent.  
 
Increase in size ≥2-fold within 4 months of first injection.  Patients who develop new locoregional disease 
during treatment may be treated additionally with the study agent at the PI discretion, in keeping with 
standard practice for other cancer histologies.  
 
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).  
 
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.  
 
 
 
Patients will be treated for a maximum of 52 weeks with intralesional injection occurring every 2 weeks.

7.1 DISCONTINUATION OF STUDY INTERVENTION 
 
Discontinuation from T-VEC does not mean discontinuation from the study, and remaining study procedures 
should be completed as indicated by the study protocol. If a clinically significant finding is identified (including, but 
not limited to changes from baseline) after enrollment, the investigator or qualified designee will determine if any 
change in participant management is needed. Any new clinically relevant finding within 4 weeks of last T-VEC 
injection will be reported as an adverse event (AE). 
In the absence of treatment delays due to adverse events, treatment may continue for 12 months or until one of 
the following criteria apply: 
1. Complete response with no cutaneous angiosarcoma to inject 
2. Disease progression as per section 8.1.2.3 
3. Deterioration in performance status precluding further treatment 
4. G4/5 adverse events persisting ≥2 weeks 
5. Patient decides to withdraw from the study, or 
6. PI decision 
 
7.2 PARTICIPANT DISCONTINUATION/WITHDRAWAL FROM THE STUDY 
 
Participants are free to withdraw from participation in the study at any time upon request. 
An investigator may discontinue or withdraw a participant from the study for the following reasons: 
 
 
Pregnancy 
 
Significant study intervention non-compliance  
 
If any clinical adverse event (AE), laboratory abnormality, or other medical condition or situation occurs 
such that continued participation in the study would not be in the best interest of the participant 
 
Disease progression which requires discontinuation of the study intervention 
 
If the participant meets an exclusion criterion (either newly developed or not previously recognized) that 
precludes further study participation 
 
Participant unable to receive T-VEC injection for ≥4 weeks (two consecutive doses). 
 
The reason for participant discontinuation or withdrawal from the study will be recorded within the patient’s 
medical record and OnCore and/or the Clinical Trial Management System (CTMS). Subjects who sign the informed 
consent form but do not receive the study intervention may be replaced. Subjects who sign the informed consent 
form, receive the study intervention, and subsequently withdraw, or are withdrawn or discontinued from the 
study prior to becoming evaluable for objective response, may be replaced. 
 
7.3 LOST TO FOLLOW-UP 
 
A participant will be considered lost to follow-up if he or she fails to return for two consecutive scheduled visits 
and is unable to be contacted by the study site staff.  
 
The following actions must be taken if a participant fails to return to the clinic for a required study visit: 
 
The site will attempt to contact the participant within 24hours and reschedule the missed visit within two 
weeks and counsel the participant on the importance of maintaining the assigned visit schedule and 
ascertain if the participant wishes to and/or should continue in the study. 

T-VEC for cutaneous angiosarcoma – 
v0.4 Sept 2019 
Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
22 
 
Before a participant is deemed lost to follow-up, the investigator or designee will make every effort to 
regain contact with the participant (where possible, 3 telephone calls and, if necessary, a certified letter 
to the participant’s last known mailing address or local equivalent methods). These contact attempts 
should be documented in the participant’s medical record or study file.  
 
Should the participant continue to be unreachable, he or she will be considered to have withdrawn from 
the study with a primary reason of lost to follow-up.

measurement/assessment will be done based on the postoperative pathology report when available in the 
electronic medical record to assess degree of pathologic response to neoadjuvant therapy. Long-term follow up for 
disease recurrence/vital status/occurrence of any suspected herpetic infectious events up to 2 years after the off 
study visit date by telephone contact and/or clinical assessment at least once every 6 months (+/- 1 month) should 
be done. Patients and their close contacts should be instructed to notify the study team immediately regarding any 
suspected new herpetic infection events so that clinical evaluation of the event by the patient’s health care 
provider, PCR testing of any lesions, expedited reporting (within 24 hours of notification) to Amgen at 1-855-465-
9442 and to the FDA, and treatment as clinically indicated can be completed. 
8.1.2 EFFICACY ANALYSES 
For the purposes of meeting the secondary endpoints of this study, patients will be re-evaluated for response 
every 2 weeks prior to injection using physical examination and measurement with calipers and/or ruler.  
In addition to baseline imaging, imaging should also be obtained 12 weeks following initial documentation of 
objective response. 
 
8.1.2.1 DEFINITIONS 
 
Evaluable for toxicity.  All patients will be evaluable for toxicity from the time of their first treatment with T-VEC 
 
Evaluable for objective response. Only those patients who have measurable disease present at baseline, have 
received at least three injections at the 108 dose level, and have had their disease re-evaluated will be considered 
evaluable for response. These patients will have their response classified according to the definitions stated below.  
 
Evaluable Non-Target Disease Response. Patients who have lesions present at baseline that are evaluable but do 
not meet the definitions of measurable disease, have received at least one cycle of therapy, and have had their 
disease re-evaluated will be considered evaluable for non-target disease. The response assessment is based on the 
presence, absence, or unequivocal progression of the lesions.  
 
Disease Parameters 
 
Measurable disease. Measurable lesions are defined as those that can be accurately measured in at least one 
dimension (longest diameter to be recorded) as ≥ 6 mm by calipers on clinical examination. All tumor 
measurements must be recorded in millimeters (or decimal fractions of centimeters). 
 
Non-measurable disease. All other lesions (or sites of disease), including small lesions (longest diameter < 6 mm 
are considered non-measurable disease.   
 
Note: Cystic lesions that meet the criteria for radiographically defined simple cysts should not be considered as 
malignant lesions (neither measurable nor non-measurable) since they are, by definition, simple cysts. 
 
“Cystic lesions” thought to represent cystic metastases can be considered as measurable lesions if they meet the 
definition of measurability described above. However, if non-cystic lesions are present in the same patient, these 
are preferred for selection as target lesions. 
 
Target lesions. All measurable lesions up to a maximum of 5 lesions in total, representative of all involved organs, 
should be identified as target lesions and recorded and measured at baseline. Target lesions should be selected on 
the basis of their size (lesions with the longest diameter), but in addition should be those that lend themselves to 

T-VEC for cutaneous angiosarcoma – 
v0.4 Sept 2019 
Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
24 
reproducible repeated measurements. It may be the case that, on occasion, the largest lesion does not lend itself 
to reproducible measurement in which circumstance the next largest lesion that can be measured reproducibly 
should be selected. A sum of the diameters (longest for non-nodal lesions, short axis for nodal lesions) for all target 
lesions will be calculated and reported as the baseline sum diameters. The baseline sum diameters will be used as 
reference to further characterize any objective tumor regression in the measurable dimension of the disease.   All 
target lesions will also be injected lesions. 
 
Non-target lesions. All other lesions (or sites of disease) including any measurable lesions over and above the 5 
target lesions should be identified as non-target lesions and should also be recorded at baseline. Measurements of 
these lesions are not required, but the presence, absence, or in rare cases unequivocal progression of each should 
be noted throughout follow-up.   All non-target lesions will not be injected with T-VEC. 
 
Methods for Evaluation of Measurable Disease 
 
All measurements should be taken and recorded in metric notation using a ruler or calipers.  All baseline 
evaluations should be performed as closely as possible to the beginning of treatment and never more than 4 
weeks before the beginning of the treatment. 
 
Clinical lesions. Clinical lesions will only be considered measurable when they are superficial (e.g., skin nodules and 
palpable lymph nodes) and ≥ 6 mm diameter as assessed using calipers.  Documentation by color photography at 
baseline, including a ruler to estimate the size of the lesion, is recommended. 
8.1.2.2 GUIDELINES FOR EVALUATION OF CLINICAL DISEASE 
All measurements of a palpable lesion should be taken and recorded in metric notation using a ruler or calipers at 
each study visit. If the lesion is not present, then it should be noted as such in the patient EMR. 
 
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.  
 
8.1.2.3 RESPONSE CRITERIA 
Evaluation of Target Lesions 
 
Complete Response (CR): Disappearance of all target lesions.   
 
Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference 
the baseline sum diameters. 
 
Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference 
the smallest sum on study (this includes the baseline sum if that is the smallest on study). (Note: the appearance of 
one or more new lesions is also considered progression). 
 
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as 
reference the smallest sum diameters while on study. 
 
Evaluation of Non-Target Lesions 
 

T-VEC for cutaneous angiosarcoma – 
v0.4 Sept 2019 
Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
25 
Complete Response (CR): Disappearance of all non-target lesions and normalization of tumor marker level.  
 
Progressive Disease (PD): Appearance of one or more new lesions and/or unequivocal progression of existing non-
target lesions. Unequivocal progression should not normally trump target lesion status. It must be representative 
of overall disease status change, not a single lesion increase. 
 
Although a clear progression of “non-target” lesions only is exceptional, the opinion of the treating physician 
should prevail in such circumstances, and the progression status should be confirmed at a later time by the review 
panel (or Principal Investigator).  Photography of these changes is recommended. 
 
Evaluation of Best Overall Response 
 
The best overall response is the best response recorded from the start of the treatment until disease 
progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the 
treatment started). The patient's best response assignment will depend on the achievement of both measurement 
and confirmation criteria.

Note:  Patients with a global deterioration of health status requiring discontinuation of treatment without 
objective evidence of disease progression at that time should be reported as “symptomatic deterioration.” Every 
effort should be made to document the objective progression even after discontinuation of treatment. 
 
Objective response—Response and progression will be evaluated in this study using a primary endpoint of 
objective response, which is defined as either complete or partial response 
 
8.1.2.4 DURATION OF RESPONSE 
Duration of Response 
 
Duration of overall response: The duration of overall response is measured from the time measurement criteria 
are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is 
objectively documented (taking as reference for progressive disease the smallest measurements recorded since 
the treatment started). 

T-VEC for cutaneous angiosarcoma – 
v0.4 Sept 2019 
Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
26 
 
The duration of overall CR is measured from the time measurement criteria are first met for CR until the first date 
that progressive disease is objectively documented. 
 
Duration of stable disease: Stable disease is measured from the start of the treatment until the criteria for 
progression are met, taking as reference the smallest measurements recorded since the treatment started, 
including the baseline measurements. 
 
8.1.2.5 PROGRESSION-FREE SURVIVAL 
Progression-free survival is defined as the duration of time from start of treatment to time of progression or death, 
whichever comes first. 
8.1.2.6 FOLLOW-UP PERIOD 
 
The study will continue to follow patient’s recurrence/vital status and any evidence of latent herpetic infection up 
to 2 years out from the start of injections, by reviewing routine clinic visit notes and/or telephone contact every six 
months (see also section 7). 
 
8.1.2.7 PATHOLOGIC RESPONSE REVIEW 
Pathology from biopsies will be reviewed for response by Moffitt Cancer Center (MCC) pathologists. 
 
8.2 SAFETY AND OTHER ASSESSMENTS 
 
Adverse event means any untoward medical occurrence associated with the use of an intervention in humans, 
whether or not considered intervention-related (21 CFR 312.32 (a). 
 
An adverse event or suspected adverse reaction is considered "serious" if, in the view of either the investigator or 
sponsor, it results in any of the following outcomes:  
• 
death,  
• 
a life-threatening adverse event,  
• 
inpatient hospitalization or prolongation of existing hospitalization,  
• 
a persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions, or  
• 
a congenital anomaly/birth defect.  
 
Important medical events that may not result in death, be life-threatening, or require hospitalization may be 
considered serious when, based upon appropriate medical judgment, they may jeopardize the patient or subject 
and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. Examples 
of such medical events include allergic bronchospasm requiring intensive treatment in an emergency room or at 
home, blood dyscrasias or convulsions that do not result in inpatient hospitalization, or the development of drug 
dependency or drug abuse. 

T-VEC for cutaneous angiosarcoma – 
v0.4 Sept 2019 
Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
27 
 
The occurrence of an adverse event (AE) or serious adverse event (SAE) may come to the attention of study 
personnel during study visits and interviews of a study participant presenting for medical care, or upon review by a 
study monitor. 
 
Adverse events can be spontaneously reported or elicited during open-ended questioning, examination, or 
evaluation of a patient. 
 
All AEs, including local and systemic reactions not meeting the criteria for SAEs, will be captured on the 
appropriate case report form (CRF). Information to be collected will include event description, time of onset, 
clinician’s assessment of severity, relationship to study product (assessed only by those with the training and 
authority to make a diagnosis), and time of resolution/stabilization of the event. All AEs occurring while on study 
must be documented appropriately regardless of relationship. All AEs will be followed to adequate resolution. 
 
Any medical condition that is present at the time that the participant is screened will be considered as baseline 
and not reported as an AE. However, if the study participant’s condition deteriorates at any time during the study, 
it will be recorded as an AE.  
 
Changes in the severity of an AE will be documented to allow an assessment of the duration of the event at each 
level of severity to be performed. AEs characterized as intermittent require documentation of onset and duration 
of each episode. 
 
All events beginning with start of study intervention until 30 days after the last day of study intervention will be 
reported. At each study visit, the investigator will inquire about the occurrence of AE/SAEs since the last visit. 
Events will be followed for outcome information until resolution or stabilization.] 
 
Data will be captured in Oncore, Moffitt’s Clinical Trials Database. Regulatory documents and case report forms 
will be monitored internally according to Moffitt Cancer Center Monitoring Policies. All adverse events will be 
documented in electronic medical records, and staff will maintain an adverse event log for each patient. The 
principal or treating physician will determine toxicity grade and attribution to the study drug, talimogene 
laherparepvec, with final approval within 10 working days of the assessment. The completed and signed-off logs 
will be provided for data entry to the assigned data manager within 24 hours of the sign off. The adverse event 
data entry will be completed within 10 working days. All adverse events must be followed to resolution or 
stabilization for a minimum of 30 days after last protocol treatment, or death (whichever occurs first) and updated 
at the time of the next assessment, treatment, discontinuation, or completion. All logs must be available for review 
and audit. All deaths that occur while the subject is receiving the study drug and/or a minimum of 30 days after 
administration will be reported as a serious adverse event.  
 
Serious adverse events will be reported to the Protocol Monitoring Committee, the FDA, the Manager of the 
Institutional Regulatory Affairs, and Amgen within 24 hours (1 day) of learning of the event. All SAEs will be 
reported to the Clinical Trial Office of Moffitt Cancer Center in 24 hours via the CTO SAE Right Fax (813-449-8486). 
Serious adverse events will be reported to the Institutional Review Board (IRB) according to IRB policy. This 
includes new herpetic infections in talimogene laherparepvec-treated patients or their close contacts as required 
by Amgen and the FDA. The initial report submitted via MedWatch form to the Office of Institutional Regulatory 
Affairs for Investigation Drugs and Devices must be as complete as possible, including details of the current illness 
and serious adverse event, and an assessment of the causal relationship between the event and the investigational 
product(s). Information not available at the time of the initial report (e.g., an end date for the adverse event or 
laboratory values received after the report) must be documented on a follow-up report. A final report to 
document resolution of the serious adverse event is required if it is not documented in the initial report. 
 
The Moffitt Office of Institutional Regulatory Affairs will complete the necessary documents and provide the report 
to the FDA as an official submission to the IND. This will occur independently of any other use of the MedWatch 
form or required reporting of serious adverse events. Submission of the MedWatch form to any other agency,

including the FDA, does not fulfill this IND Safety Reporting requirement. Follow-up to the safety report must also 
be submitted to the Office of Institutional Regulatory Affairs in a timely manner.  
 
Upon completion of the report, a copy of all initial and follow-up MedWatch forms will be faxed to Manager, 
Moffitt Office of Institutional Regulatory Affairs, with call or email made to confirm receipt. 
 
For unexpected fatal or life-threatening experiences associated with the use of the investigational product(s), the 
Office of Institutional Regulatory Affairs will be contacted within 24 hours. Additionally, the Clinical Trial Office of 
Moffitt Cancer Center will be alerted within 24 hours of the event via the CTO SAE Right Fax (813-449-8486). 
Notification to Amgen will be made within 24 hours (1 day) of the event. Notification to the FDA will be made as 
soon as possible, but no later than 7 calendar days after initial receipt of the information. 
 
Safety information for Amgen, the supplier of talimogene laherparepvec, will be exchanged as follows: All serious 
adverse events will be sent in individual report forms batched every 90 days. Suspected unexpected SAEs will be 
submitted at the time of regulatory submission, which will be within seven working days. Adverse drug reactions 
that are not serious will be sent as a listing at the end of the study. Product complaints, medication errors or 
overdoses, misuse, abuse, transmission of infectious agent, or unauthorized use (when associated with an adverse 
event) will be sent to Amgen within one working day of sponsor awareness. Amgen should be notified of patients 
who become pregnant during the trial within 10 days of the sponsor awareness. Amgen does not require 
notification of events that are not considered related to talimogene laherparepvec, regardless of seriousness and 
events of interest.

8.3.1 ANALYSIS OF TUMOR-INFILTRATING LYMPHOCYTES FROM TUMOR SPECIMENS 
Background: We have recently completed a pilot protocol that focused on the immune infiltrate of 15 patient-
derived sarcoma specimens. In this sample, 57% were high-grade tumors, 36% were recurrent tumors, and 29% 
had preoperative therapy. Analysis of tumor digest showed that 48% (range, 3.6%-76%) of cells from the 
lymphocyte gate were CD3+. There is significant heterogeneity of the immune infiltrate phenotype with respect to 
CD3+CD8+ fraction within the tumor digest between samples and much more so than seen in the prior experience 
from melanoma in our laboratory. Tumor-infiltrating lymphocytes (TIL) were grown from fragments of all 
specimens with TIL observed in 152 of 192 (79%) fragments. The phenotype of the CD3+ subpopulations from TIL 
cultures included an average 50% (range, 13%-91%) CD8+ and 34% (range, 5%-79%) CD4+ cells. 
Methods: The tumor sample obtained from punch biopsy will be minced, placed in a conical vial with rotating 
agitator (C tube), and processed on a gentleMACS tissue dissociator (Miltenyi Biotec). The C tube will be incubated 
at 37°C between gentleMACS mechanical disruption cycles. Resulting digest will be filtered through 100-μm filters 
and counted to verify the tumor cell component, TIL component, and viability. Digest suspension (5 x 105 cells) will 
be placed in a 48-well plate in culture media containing 6000 IU/mL of IL-2 to generate TIL cultures from the 
primary tumor. To determine the phenotype of the TIL, flow cytometry will be conducted on the TIL culture. The

v0.4 Sept 2019 
Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019

tumor immune filtrate will be characterized using a standard, validated panel of antibodies to determine the 
expression of CD3, CD4, CD8, CD16, and CD56.  To determine the activation status  of the TIL, flow cytometry using 
intracellular interferon-gamma staining techniques will be performed. 
 
8.4 ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS 
 
8.4.1 DEFINITION OF ADVERSE EVENTS (AE) 
 
Adverse event means any untoward medical occurrence associated with the use of an intervention in humans, 
whether or not considered intervention-related (21 CFR 312.32 (a). 
 
8.4.2 DEFINITION OF SERIOUS ADVERSE EVENTS (SAE)  
 
An adverse event or suspected adverse reaction is considered "serious" if, in the view of either the investigator or 
sponsor, it results in any of the following outcomes:  
• 
death,  
• 
a life-threatening adverse event,  
• 
inpatient hospitalization or prolongation of existing hospitalization,  
• 
a persistent or significant incapacity or substantial disruption of the ability to conduct normal life 
functions, or  
• 
a congenital anomaly/birth defect.  
 
Important medical events that may not result in death, be life-threatening, or require hospitalization may be 
considered serious when, based upon appropriate medical judgment, they may jeopardize the patient or subject 
and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. Examples 
of such medical events include allergic bronchospasm requiring intensive treatment in an emergency room or at 
home, blood dyscrasias or convulsions that do not result in inpatient hospitalization, or the development of drug 
dependency or drug abuse 
 
8.4.3 CLASSIFICATION OF AN ADVERSE EVENT 
 
8.4.3.1 SEVERITY OF EVENT 
All AEs will be graded using the CTCAE 5.0 criteria. 
For AEs not included in the protocol-defined grading system, the following guidelines will be used to describe 
severity. 
Mild – Events require minimal or no treatment and do not interfere with the participant’s daily activities. 
Moderate – Events result in a low level of inconvenience or concern with the therapeutic measures. Moderate 
events may cause some interference with functioning. 
Severe – Events interrupt a participant’s usual daily activity and may require systemic drug therapy or other 
treatment. Severe events are usually potentially life-threatening or incapacitating. Of note, the term “severe” does 
not necessarily equate to “serious”. 
8.4.3.2 RELATIONSHIP TO STUDY INTERVENTION 
 

T-VEC for cutaneous angiosarcoma – 
v0.4 Sept 2019 
Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
30 
For all collected AEs, the clinician who examines and evaluates the participant will determine the AE’s causality 
based on temporal relationship and his/her clinical judgment. The degree of certainty about causality will be 
graded using the categories below. 
 
• 
Definitely Related – There is clear evidence to suggest a causal relationship, and other possible contributing 
factors can be ruled out. The clinical event, including an abnormal laboratory test result, occurs in a plausible 
time relationship to drug administration and cannot be explained by concurrent disease or other drugs or 
chemicals. The response to withdrawal of the drug (dechallenge) should be clinically plausible. The event must 
be pharmacologically or phenomenologically definitive, with use of a satisfactory rechallenge procedure if 
necessary. 
• 
Probably Related – There is evidence to suggest a causal relationship, and the influence of other factors is 
unlikely. The clinical event, including an abnormal laboratory test result, occurs within a reasonable time after 
administration of the drug, is unlikely to be attributed to concurrent disease or other drugs or chemicals, and 
follows a clinically reasonable response on withdrawal (dechallenge). Rechallenge information is not required 
to fulfill this definition. 
• 
Possibly Related – There is some evidence to suggest a causal relationship (eg, the event occurred within a 
reasonable time after administration of the trial medication). However, other factors may have contributed to 
the event (eg, the participant’s clinical condition, other concomitant events). Although an AE may rate only as 
“possibly related” soon after discovery, it can be flagged as requiring more information and later be upgraded 
to “probably related” or “definitely related,” as appropriate. 
• 
Unlikely to be related – A clinical event, including an abnormal laboratory test result, whose temporal 
relationship to drug administration makes a causal relationship improbable (eg, the event did not occur within 
a reasonable time after administration of the trial medication) and in which other drugs or chemicals or 
underlying disease provides plausible explanations (eg, the participant’s clinical condition, other concomitant 
treatments). 
• 
Not Related – The AE is completely independent of study drug administration, and/or evidence exists that the 
event is definitely related to another etiology. There must be an alternative, definitive etiology documented 
by the clinician. 
 
8.4.3.3 EXPECTEDNESS  
The PI will be responsible for determining whether an AE is expected or unexpected. An AE will be considered 
unexpected if the nature, severity, or frequency of the event is not consistent with the risk information previously 
described for the study agent. 
8.4.4 TIME PERIOD AND FREQUENCY FOR EVENT ASSESSMENT AND 
FOLLOW-UP 
 
The occurrence of an adverse event (AE) or serious adverse event (SAE) may come to the attention of study 
personnel during study visits and interviews of a study participant presenting for medical care, or upon review by a 
study monitor. 
 
Adverse events can be spontaneously reported or elicited during open-ended questioning, examination, or 
evaluation of a patient. 
 
All AEs, including local and systemic reactions not meeting the criteria for SAEs, will be captured on the 
appropriate case report form (CRF). Information to be collected will include event description, time of onset, 
clinician’s assessment of severity, relationship to study product (assessed only by those with the training and 
authority to make a diagnosis), and time of resolution/stabilization of the event. All AEs occurring while on study 
must be documented appropriately regardless of relationship. All AEs will be followed to adequate resolution. 
 

T-VEC for cutaneous angiosarcoma –

Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
31 
Any medical condition that is present at the time that the participant is screened will be considered as baseline 
and not reported as an AE. However, if the study participant’s condition deteriorates at any time during the study, 
it will be recorded as an AE.  
 
Changes in the severity of an AE will be documented to allow an assessment of the duration of the event at each 
level of severity to be performed. AEs characterized as intermittent require documentation of onset and duration 
of each episode. 
 
All events beginning with start of study intervention until 30 days after the last day of study intervention will be 
reported. At each study visit, the investigator will inquire about the occurrence of AE/SAEs since the last visit. 
Events will be followed for outcome information until resolution or stabilization. 
 
8.4.5 ADVERSE AND SERIOUS ADVERSE EVENT REPORTING  
 
The occurrence of an adverse event (AE) or serious adverse event (SAE) may come to the attention of study 
personnel during study visits and interviews of a study participant presenting for medical care, or upon review by a 
study monitor. 
Adverse events can be spontaneously reported or elicited during open-ended questioning, examination, or 
evaluation of a patient. 
All AEs, including local and systemic reactions not meeting the criteria for SAEs, will be captured on the 
appropriate case report form (CRF). Information to be collected will include event description, time of onset, 
clinician’s assessment of severity, relationship to study product (assessed only by those with the training and 
authority to make a diagnosis), and time of resolution/stabilization of the event. All AEs occurring while on study 
must be documented appropriately regardless of relationship. All AEs will be followed to adequate resolution. 
Any medical condition that is present at the time that the participant is screened will be considered as baseline 
and not reported as an AE. However, if the study participant’s condition deteriorates at any time during the study, 
it will be recorded as an AE.  
Changes in the severity of an AE will be documented to allow an assessment of the duration of the event at each 
level of severity to be performed. AEs characterized as intermittent require documentation of onset and duration 
of each episode. 
All events beginning with start of study intervention until 30 days after the last day of study intervention will be 
reported. At each study visit, the investigator will inquire about the occurrence of AE/SAEs since the last visit. 
Events will be followed for outcome information until resolution or stabilization.] 
Data will be captured in Oncore, MCC’s Clinical Trials Database. Regulatory documents and case report forms will 
be monitored internally according to MCC Monitoring Policies. All adverse events will be documented in electronic 
medical records, and staff will maintain an adverse event log for each patient. The principal or treating physician 
will determine toxicity grade and attribution to the study drug, T-VEC, with final approval within 10 working days 
of the assessment. The completed and signed-off logs will be provided for data entry to the assigned data manager 
within 24 hours of the sign off. The adverse event data entry will be completed within 10 working days. All adverse 
events must be followed to resolution or stabilization for a minimum of 30 days after last protocol treatment, or 
death (whichever occurs first) and updated at the time of the next assessment, treatment, discontinuation, or

completion. All logs must be available for review and audit. All deaths that occur while the subject is receiving the 
study drug and/or a minimum of 30 days after administration will be reported as a serious adverse event.  
Serious adverse events will be reported to the Protocol Monitoring Committee, the FDA, the Manager of the 
Institutional Regulatory Affairs, and Amgen within 24 hours (1 day) of learning of the event. All SAEs will be 
reported to the Clinical Trial Office of MCC in 24 hours via the CTO SAE Right Fax (813-449-8486). Serious adverse 
events will be reported to the Institutional Review Board (IRB) according to IRB policy. This includes new herpetic 
infections in T-VEC-treated patients or their close contacts (see Section 7.2) as required by Amgen and the FDA. 
The initial report submitted via MedWatch form to the Office of Institutional Regulatory Affairs for Investigation 
Drugs and Devices must be as complete as possible, including details of the current illness and serious adverse 
event, and an assessment of the causal relationship between the event and the investigational product(s). 
Information not available at the time of the initial report (e.g., an end date for the adverse event or laboratory 
values received after the report) must be documented on a follow-up report. A final report to document resolution 
of the serious adverse event is required if it is not documented in the initial report. 
Upon completion of the report, a copy of all initial and follow-up MedWatch forms will be faxed to Manager, MCC 
Office of Institutional Regulatory Affairs, with call or email made to confirm receipt. 
For unexpected fatal or life-threatening experiences associated with the use of the investigational product(s), the 
Office of Institutional Regulatory Affairs will be contacted within 24 hours. Additionally, the Clinical Trial Office of 
MCC will be alerted within 24 hours of the event via the CTO SAE Right Fax (813-449-8486). Notification to Amgen 
will be made within 24 hours (1 day) of the event. Notification to the FDA will be made as soon as possible, but no 
later than 7 calendar days after initial receipt of the information. 
8.4.6 SAFETY DATA EXCHANGE FOR AMGEN  
The Sponsor/Investigator is responsible for compliance with expedited reporting requirements for serious, 
unexpected and related adverse events (SUSARs), for generation of SAE reports including narratives, and for 
periodic reporting to Amgen of SAEs as outlined in the tables below. 
 
 

T-VEC for cutaneous angiosarcoma –

Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
33 
 
In addition to the requirements outlined in Table 1 and 2, Sponsor/Investigators are required to report direct 
exposures to talimogene laherparepvec (e.g., needle stick, splash back) of herpetic illness and all suspected 
herpetic events.  HCPs involved in your clinical trial who were directly exposed to talimogene laherparepvec (e.g., 
needle stick, splash back) but who are without signs or symptoms of herpetic illness should be reported to Amgen 
at 1-855-IMLYGIC (1-855-465-9442). 
Suspected herpetic events must be reported to Amgen within 24 hours of awareness. Reporting is required for: (1) 
suspected herpetic events in treated patients; (2) suspected herpetic events in at risk HCPs with direct or indirect 
exposure and 3) suspected herpetic events in treated patient’s close contacts, as outlined in Table 3.  
In addition to reporting these events, suspected herpetic lesions should be swabbed and submitted for qPCR 
testing for the detection of talimogene laherparepvec. Samples should be collected using appropriate technique 
and a flocked swab from site supplies. This test is likely to be more reliable if performed within the first three days 
of symptom appearance; however, all lesions should be swabbed, regardless of the timing of presentation. Amgen 
does not require qPCR or other testing for wild type HSV-1. 
Reporting Process for ISS Treated Patients: 
 
Any suspected herpetic lesion should be reported to Amgen at 1-855-IMLYGIC (1-855-465-9442), 
evaluated by the Sponsor/Investigator and swabbed for qPCR testing. 
 
Once an initial report has been made, additional materials will be provided, including reporting forms and 
supplies needed for shipment of swab samples. Amgen will require patient consent for qPCR testing, 
which must be obtained prior to swabbing. 
Reporting Process for HCPs and Close Contacts: 
 
Sponsor/Investigator should advise any HCPs and/or Close Contacts with suspected herpetic lesions to 
contact their personal physician to facilitate reporting to Amgen. Suspected herpetic lesions can be 
reported by the Sponsor / Investigator, personal physician or exposed individual to Amgen at 1-855-
IMLYGIC (1-855-465-9442). Once an initial report has been made, additional materials will be provided,

including reporting forms and supplies needed for the shipment of swab samples. Amgen will require 
patient consent for qPCR testing, which must be obtained prior to swabbing 
 
Additionally, Amgen requires annual submission of IND annual report safety data, as well as an End of Study 
Report at the time of ISS sponsor submission to the Institutional Review Board (IRB; no later than one calendar 
year from study completion).  
Serious adverse events will be reported to the Protocol Monitoring Committee, the FDA, the Manager of the 
Institutional Regulatory Affairs, and Amgen within 24 hours (1 day) of learning of the event. All SAEs will be 
reported to the Clinical Trial Office of Moffitt Cancer Center in 24 hours via the CTO SAE Right Fax (813-449-8486). 
Serious adverse events will be reported to the Institutional Review Board (IRB) according to IRB policy. This 
includes new herpetic infections in talimogene laherparepvec-treated patients or their close contacts as required 
by Amgen and the FDA. The initial report submitted via MedWatch form to the Office of Institutional Regulatory 
Affairs for Investigation Drugs and Devices must be as complete as possible, including details of the current illness 
and serious adverse event, and an assessment of the causal relationship between the event and the investigational 
product(s). Information not available at the time of the initial report (e.g., an end date for the adverse event or 
laboratory values received after the report) must be documented on a follow-up report. A final report to 
document resolution of the serious adverse event is required if it is not documented in the initial report.

The Moffitt Office of Institutional Regulatory Affairs will complete the necessary documents and provide the report 
to the FDA as an official submission to the IND. This will occur independently of any other use of the MedWatch 
form or required reporting of serious adverse events. Submission of the MedWatch form to any other agency,

8.5 UNANTICIPATED PROBLEMS 
 
8.5.1 DEFINITION OF UNANTICIPATED PROBLEMS (UP) 
 
The Office for Human Research Protections (OHRP) considers unanticipated problems involving risks to participants 
or others to include, in general, any incident, experience, or outcome that meets all of the following criteria: 
 
• 
Unexpected in terms of nature, severity, or frequency given (a) the research procedures that are 
described in the protocol-related documents, such as the Institutional Review Board (IRB)-approved 
research protocol and informed consent document; and (b) the characteristics of the participant 
population being studied; 
• 
Related or possibly related to participation in the research (“possibly related” means there is a reasonable 
possibility that the incident, experience, or outcome may have been caused by the procedures involved in 
the research); and 
• 
Suggests that the research places participants or others at a greater risk of harm (including physical, 
psychological, economic, or social harm) than was previously known or recognized. 
 
8.5.2  UNANTICIPATED PROBLEM REPORTING  
 
The investigator will report unanticipated problems (UPs) to the reviewing Institutional Review Board (IRB) and to 
the Protocol Monitoring Committee (PMC) of the institution. The UP report will include the following information: 
 
• 
Protocol identifying information: protocol title and number, PI’s name, and the IRB project number; 
• 
A detailed description of the event, incident, experience, or outcome;  
• 
An explanation of the basis for determining that the event, incident, experience, or outcome represents 
an UP;  
• 
A description of any changes to the protocol or other corrective actions that have been taken or are 
proposed in response to the UP. 
 
To satisfy the requirement for prompt reporting, UPs will be reported using the following timeline:  
 
• 
UPs that are serious adverse events (SAEs) will be reported to the IRB and to the PMC/study sponsor 
within 24hours of the investigator becoming aware of the event.  
• 
Any other UP will be reported to the IRB and to the PMC/study sponsor within 24 hours of the 
investigator becoming aware of the problem.  
• 
All UPs should be reported to appropriate institutional officials (as required by an institution’s written 
reporting procedures), the supporting agency head (or designee), and the Office for Human Research 
Protections (OHRP) within 24 hours of the IRB’s receipt of the report of the problem from the investigator.

STATISTICAL CONSIDERATIONS  
 
 
9.1 STATISTICAL HYPOTHESES

T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
37 
For the primary endpoint, the optimal two-stage design to test the null hypothesis that P0 ≤ 0.10 versus the 
alternative that P1 ≥ 0.40.  
 
9.2 SAMPLE SIZE DETERMINATION 
For the primary endpoint, the optimal two-stage design to test the null hypothesis that P0 ≤ 0.10 versus the 
alternative that P1 ≥ 0.40 has an expected sample size of 8.93 and a probability of early termination of 0.813. If the 
treatment is actually not effective, there is a 0.031 probability of concluding that it is (the target for this value was 
0.050). If the treatment is actually effective, there is a 0.198 probability of concluding that it is not (the target for 
this value was 0.200). After testing the treatment on 8 patients in the first stage, the trial will be terminated if 1 or 
fewer responds.   If the trial goes on to the second stage, a total of 13 patients will be studied. If the total number 
responding is less than or equal to 3, the treatment is rejected. 
 
9.3 POPULATIONS FOR ANALYSES 
The analysis datasets (e.g., which participants will be included in each analysis) include the following: 
 
 
Intention-to-Treat (ITT) Analysis Dataset  
 
Safety Analysis Dataset: defines the subset of participants for whom safety analyses will be conducted 
(e.g., participants who took at least one dose of study intervention) 
 
Per-Protocol Analysis Dataset: defines a subset of the participants in the full analysis (ITT) set who 
complied with the protocol sufficiently to ensure that these data would be likely to represent the effects 
of study intervention according to the underlying scientific model (e.g., participants who took at least 80% 
of study intervention for 80% of the days within the maintenance period) 
 
9.4 STATISTICAL ANALYSES 
 
9.4.1 GENERAL APPROACH 
For the primary endpoint, we will use the Simon’s two stage approach as described in detail above in the Sample 
Size Determination Section.  For the secondary endpoints we will use descriptive statistics as well as the Kaplan-
Meier approach for the time to event endpoints. 
All analyses will be performed in either SAS v. 9.4 or R software using standard procedures and packages. 
9.4.2 ANALYSIS OF THE PRIMARY EFFICACY ENDPOINT(S) 
 
Our primary endpoint for this analysis will be confirmed overall response rate (ORR) in injected lesions 
based on modified RECIST criteria appropriate for cutaneous neoplasms (ORR = complete response + 
partial response)  
 
According to the Simon’s two-stage design, after testing the treatment on 8 patients in the first stage, 
the trial will be terminated if 1 or fewer responds.   If the trial goes on to the second stage, a total of 13 
patients will be studied. If the total number responding is less than or equal to 3, the treatment is 
rejected.  Please see Sample Size description above for further details. 
 
In addition, we will construct a 95% exact confidence interval for the ORR. 

T-VEC for cutaneous angiosarcoma –

Protocol 19878 
 
T-VEC for cutaneous angiosarcoma – v0.4 Sept 2019 
38 
 
9.4.3 ANALYSIS OF THE SECONDARY ENDPOINT(S) 
 
For all secondary endpoints except those with time-to-event responses, we will use basic descriptive statistics such 
as the mean, median, standard deviation and range for continuous variables and frequencies for categorical 
variables.    We will construct exact 95% confidence intervals to describe these secondary endpoints. 
 
For time-to-event responses, we will use Kaplan-Meier estimates and plots to describe the endpoints.  Response 
duration is measured from the time of first injection to initial partial response or complete response.  Progression 
free survival is measured from time of first injection to progression of disease or appearance of new CA, not 
present at the time of study entry.  The median progression-free survival will be reported with 95% confidence 
interval. 
 
All secondary endpoints are for descriptive purposes, and no power analyses have been performed for them. 
9.4.4 SAFETY ANALYSES 
 
Safety will be analyzed using descriptive reporting of all AE.   Toxicity will be reported by type, frequency 
and severity in tabular format.  Final reporting will include reasons for discontinuation related to the 
study drug.   Monthly PMC meeting review of AE/SAE will serve as guidance to PI regarding the rate of 
AEs for each organ system based on CTCAE v4.03. 
 
9.4.5 BASELINE DESCRIPTIVE STATISTICS 
 
Given the study design and patient enrollment, descriptive statistics will not be used to stratify or perform 
subgroup analyses.  Baseline descriptive characteristics will be described using standard descriptive statistics 
including the mean, median, standard deviation and range for continuous variables and frequencies for categorical 
variables.  We will not use inferential statistics here as the purpose is descriptive only in nature. 
 
9.4.6 PLANNED INTERIM ANALYSES  
 
Please see the Sample Size section about describing in detail the Simon’s two-stage approach that we 
will be using. According to the Simon’s two-stage design, after testing the treatment on 8 patients in the 
first stage, the trial will be terminated if 1 or fewer responds.    
 
We do not plan any other interim analyses. 
 
9.4.7 SUB-GROUP ANALYSES 
 
There will be no subgroup analysis given the overall sample size of this trial. 
 
 
9.4.8 TABULATION OF INDIVIDUAL PARTICIPANT DATA 
 
There are no planned listings of data by measure and time point. 
 
9.4.9 EXPLORATORY ANALYSES

10.1.1 INFORMED CONSENT PROCESS 
 
10.1.1.1 
CONSENT/ASSENT AND OTHER INFORMATIONAL DOCUMENTS 
PROVIDED TO PARTICIPANTS 
 
Consent forms describing in detail the study intervention, study procedures, and risks are given to the participant 
and written documentation of informed consent is required prior to starting intervention/administering study 
intervention. The informed consent document is submitted with this protocol. 
 
10.1.1.2 
CONSENT PROCEDURES AND DOCUMENTATION 
 
Informed consent is a process that is initiated prior to the individual’s agreeing to participate in the study and 
continues throughout the individual’s study participation. Consent forms will be Institutional Review Board (IRB)-
approved and the participant will be asked to read and review the document. The investigator will explain the 
research study to the participant and answer any questions that may arise. A verbal explanation will be provided in 
terms suited to the participant’s comprehension of the purposes, procedures, and potential risks of the study and 
of their rights as research participants. Participants will have the opportunity to carefully review the written 
consent form and ask questions prior to signing. The participants should have the opportunity to discuss the study 
with their family or surrogates or think about it prior to agreeing to participate. The participant will sign the 
informed consent document prior to any procedures being done specifically for the study. Participants must be 
informed that participation is voluntary and that they may withdraw from the study at any time, without prejudice. 
A copy of the informed consent document will be given to the participants for their records. The informed consent 
process will be conducted and documented in the source document (including the date), and the form signed, 
before the participant undergoes any study-specific procedures. The rights and welfare of the participants will be 
protected by emphasizing to them that the quality of their medical care will not be adversely affected if they 
decline to participate in this study. 
10.1.2 STUDY DISCONTINUATION AND CLOSURE 
 
This study may be temporarily suspended or prematurely terminated if there is sufficient reasonable cause. 
Written notification, documenting the reason for study suspension or termination, will be provided by the 
suspending or terminating party to study participants, investigator, and regulatory authorities. If the study is 
prematurely terminated or suspended, the Principal Investigator (PI) will promptly inform study participants, the 
Institutional Review Board (IRB), and sponsor and will provide the reason(s) for the termination or suspension. 
Study participants will be contacted, as applicable, and be informed of changes to study visit schedule. 
  
Circumstances that may warrant termination or suspension include, but are not limited to: 
 
Determination of unexpected, significant, or unacceptable risk to participants 
 
Demonstration of efficacy that would warrant stopping   
 
Insufficient compliance to protocol requirements 
 
Data that are not sufficiently complete and/or evaluable 


Study may resume once concerns about safety, protocol compliance, and data quality are addressed, and satisfy 
the sponsor, IRB and/or Food and Drug Administration (FDA). 
 
10.1.3 FUTURE USE OF STORED SPECIMENS AND DATA  
 
Data collected for this study will be analyzed and stored at Moffitt Cancer Center. After the study is completed, the 
de-identified, archived data will be transmitted to and stored at Moffitt Cancer Center, for use by other researchers 
including those outside of the study. Permission to transmit data to collaborators with established Material Transfer 
Agreements will be included in the informed consent.  
 
With the participant’s approval and as approved by local Institutional Review Boards (IRBs), de-identified biological 
samples will be stored at the laboratory of the PI. These samples could be used to research the causes of cancer, its 
complications and other conditions for which individuals with cancer are at increased risk, and to improve 
treatment. The PI will retain a code-link that will allow linking the biological specimens with the phenotypic data 
from each participant, maintaining the blinding of the identity of the participant. 
 
During the conduct of the study, an individual participant can choose to withdraw consent to have biological 
specimens stored for future research. However, withdrawal of consent with regard to biosample storage may not be 
possible after the study is completed.  
 
When the study is completed, access to study data and/or samples will be provided through the Mullinax Lab.

The study will be staffed by a Clinical Trial Coordinator who will work with PI to ensure that 
reporting requirements are met.   The Protocol Monitoring Committee at Moffitt Cancer Center 
will review all study amendments, deviations, AEs, and SAEs. 
 
10.1.5 SAFETY OVERSIGHT 
 
Serious Adverse Events: Serious Adverse Events (SAEs) from this protocol will be reported concurrently to the IRB 
and the study sponsor. The Protocol Monitoring Committee (PMC) will review these SAEs in accordance with the 
protocol-specific DSMP. The PMC meets monthly and reviews accrual, patterns and frequencies of all adverse 
events, protocol violations and when applicable, internal audit results.  This trial will be continuously monitored by 
the PI and the research team and reviewed at weekly Sarcoma Research Group meetings. Safety and monitoring 
reports will be submitted to the PMC after each patient completes 12 weeks of treatment more frequently if 
requested by the PMC. A final safety and monitoring report will be submitted to the PMC within three months of 
defining the MTD. This protocol will be subject to periodic internal audits based on risk or as recommended by the 
PMC.

MCC’s Internal Monitors will periodically monitor regulatory documents and case report forms according to the 
protocol specific clinical monitoring plan.  Monitoring will include review of data for accuracy, completeness, and 
source verification, reporting of SAEs, and adherence to the protocol, Good Clinical Practice (GCP) guidelines, and 
applicable regulatory requirements. 
 
10.1.7 QUALITY ASSURANCE AND QUALITY CONTROL 
 
The clinical site will perform internal quality management of study conduct, data and biological specimen 
collection, documentation and completion. An individualized quality management plan will be developed to 
describe a site’s quality management. 
 
Quality control (QC) procedures will be implemented beginning with the data entry system and data QC checks 
that will be run on the database will be generated. Any missing data or data anomalies will be communicated to 
the site(s) for clarification/resolution. 
 
Following written Standard Operating Procedures (SOPs), the monitors will verify that the clinical trial is conducted 
and data are generated and biological specimens are collected, documented (recorded), and reported in 
compliance with the protocol, International Conference on Harmonisation Good Clinical Practice (ICH GCP), and 
applicable regulatory requirements (e.g., Good Laboratory Practices (GLP), Good Manufacturing Practices (GMP)).  
 
 
10.1.8 DATA HANDLING AND RECORD KEEPING  
 
10.1.8.1 
DATA COLLECTION AND MANAGEMENT RESPONSIBILITIES  
Data will be captured in OnCore and/or MCC’s electronic Clinical Trials Management System. For each subject 
enrolled, the electronic CRF must be completed by the assigned data manager or other authorized study staff. Any 
paper forms should be typed or filled out indelible ink and must be legible. Errors should be crossed out but not 
obliterated, the correction inserted, and the change initialed and dated by the investigator or his/her authorized 
delegate. This also applies to records for those subjects who fail to complete the study. If a subject stops dosing or 
terminates from the study, the dates and reasons must be noted on the CRF.  
Data collection is the responsibility of the clinical trial staff at the site under the supervision of the site investigator. 
The investigator is responsible for ensuring the accuracy, completeness, legibility, and timeliness of the data 
reported. 
Clinical data (including adverse events (AEs), concomitant medications, and expected adverse reactions data) and 
clinical laboratory data will be entered into Oncore, a 21 CFR Part 11-compliant data capture system provided by 
MCC. The data system includes password protection and internal quality checks, such as automatic range checks, 
to identify data that appear inconsistent, incomplete, or inaccurate. Clinical data will be entered directly from the 
source documents. 
 
10.1.8.2 
STUDY RECORDS RETENTION  
Study documents should be retained for a minimum of 2 years after the last approval of a marketing application in 
an International Conference on Harmonisation (ICH) region and until there are no pending or contemplated 
marketing applications in an ICH region or until at least 2 years have elapsed since the formal discontinuation of 
clinical development of the study intervention. These documents should be retained for a longer period, however, 
if required by local regulations. No records will be destroyed without the written consent of the sponsor, if 
applicable. It is the responsibility of the sponsor to inform the investigator when these documents no longer need 
to be retained.

10.1.9 PROTOCOL DEVIATIONS  
 
A protocol deviation is any noncompliance with the clinical trial protocol, International Conference on 
Harmonisation Good Clinical Practice (ICH GCP), or Manual of Procedures (MOP) requirements. The 
noncompliance may be either on the part of the participant, the investigator, or the study site staff. As a result of 
deviations, corrective actions are to be developed by the site and implemented promptly.  
 
These practices are consistent with ICH GCP:  
• 
4.5 Compliance with Protocol, sections 4.5.1, 4.5.2, and 4.5.3  
• 
5.1 Quality Assurance and Quality Control, section 5.1.1  
• 
5.20 Noncompliance, sections 5.20.1, and 5.20.2.  
 
It is the responsibility of the site investigator to use continuous vigilance to identify and report deviations within 7 
working days of identification of the protocol deviation, or within 7 working days of the scheduled protocol-
required activity. All deviations must be addressed in study source documents and reported to Amgen. Protocol 
deviations must be sent to the reviewing Institutional Review Board (IRB) per their policies. The site investigator is 
responsible for knowing and adhering to the reviewing IRB requirements. Further details about the handling of 
protocol deviations will be included in the MOP. Deviations must be entered into the Clinical Trials Management 
System (CTMS).
