PROTOCOL SUMMARY 
Avelumab is a human immunoglobulin (Ig) G1 monoclonal antibody (mAb) directed against 
programmed death-ligand 1 (PD-L1).  Avelumab selectively binds to PD-L1 and 
competitively blocks its interaction with programmed death receptor 1 (PD-1), thereby 
interfering with this key immune checkpoint inhibition pathway.  In March 2017, avelumab 
received accelerated approval by the United States (US) Food and Drug Administration 
(FDA) as the first treatment for metastatic Merkel cell carcinoma (MCC).  In May 2017, 
avelumab received accelerated approval by the US FDA for the treatment of patients with 
locally advanced or metastatic urothelial cancer (UC) with disease progression during or 
following platinum-containing chemotherapy, or within 12 months of neoadjuvant or
adjuvant platinum-containing chemotherapy.  Avelumab is currently being investigated as 
single agent and in combination with other anti-cancer therapies in patients with locally 
advanced or metastatic solid tumors and various hematological malignancies.
With evolving data it is becoming evident that combination immunotherapy strategies will be 
necessary to achieve enhanced anti-tumor activity for patients who do not experience disease 
control with single-agent immune checkpoint inhibitors.1 Growing nonclinical and clinical 
evidence suggest that the combination of checkpoint inhibition plus anti-angiogenic agents 
may potentially improve anti-tumor activity and patient outcomes compared to results seen 
with single agents.  Vascular endothelial growth factor (VEGF) can exert 
immunosuppressive effects in tumors by inhibiting maturation of dendritic cells, promoting 
immune suppressive cell infiltration and enhancing immune checkpoint molecule 
expression.62 Likewise, immunosuppressive cells such as myeloid derived suppressor cells 
secrete pro-angiogenic factors VEGF and matrix metalloproteinase (MMP) which directly 
promote angiogenesis growth63 and induce resistance to anti-VEGF therapy.  Given the 
immunomodulatory and anti-angiogenic properties of anti-VEGF therapies, including 
axitinib,62-66 potential synergy with anti-VEGF therapy in combination with immune 
checkpoint blockade may increase clinical efficacy in patients with advanced or metastatic 
non-small cell lung cancer (NSCLC) who have received at least one prior 
platinum-containing therapy, and in treatment naïve patients with advanced or metastatic UC, 
who are ineligible for cisplatin-containing chemotherapy for their advanced disease. 
Study Objectives
Primary Objective

To evaluate the Objective Response Rate (ORR) based on Investigator assessment, 
per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 of avelumab in 
combination with axitinib in patients with advanced or metastatic NSCLC who have 
received at least one prior platinum-containing therapy and in treatment naïve patients 
with advanced or metastatic UC, who are ineligible for cisplatin-containing 
chemotherapy for their advanced disease.

Secondary Objectives
To evaluate the following in patients with advanced or metastatic NSCLC who have received 
at least one prior platinum-containing therapy and in treatment naïve patients with advanced 
or metastatic UC, who are ineligible for cisplatin-containing chemotherapy for their 
advanced disease:
•
The safety and tolerability of avelumab in combination with axitinib;
•
The anti-tumor activity of avelumab in combination with axitinib;
•
The pharmacokinetics of avelumab and axitinib when administered in combination;
•
Candidate predictive and/or early response biomarkers in pre-treatment tumor tissue 
and pre- and post-treatment blood samples that may aid in the identification of a 
patient subpopulation most likely to benefit from treatment with avelumab in 
combination with axitinib.  Assessments may include but are not limited to tumor 
mutational burden, immune repertoire and PD-L1 expression within the tumor 
microenvironment;
•
The immunogenicity of avelumab when combined with axitinib.
Study Endpoints
Primary Endpoint
Confirmed Objective Response (OR) based on Investigator assessment per RECIST v1.1.77
Secondary Endpoints
•
Adverse events (AEs) as characterized by type, severity as graded by National Cancer 
Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] v.4.03, 
(Appendix 2), timing, seriousness, and relationship to study treatments;

•
Laboratory abnormalities as characterized by type, severity (as graded by NCI 
CTCAE v.4.03) and timing;
•
Time-to-event endpoints including time to tumor response (TTR), duration of 
response (DR), progression-free survival (PFS) based on Investigator assessment per 
RECIST v1.1, and overall survival (OS);
•
Pharmacokinetic parameters including trough and maximum concentrations (Ctrough,
Cmax) of avelumab and axitinib;
•
Tumor tissue biomarker status (ie, positive or negative based on, for example, PD-L1 
expression and/or quantitation of tumor mutational burden as well as characterization 
of the immune repertoire in peripheral blood and/or tumor);
•
Anti-drug antibody (ADA) titers and neutralizing antibodies (NAb) against avelumab. 
Study Design
This is an open-label, multi-center, Phase 2 study to evaluate the safety and efficacy of 
avelumab in combination with axitinib in patients with advanced or metastatic NSCLC who 
have received at least one prior platinum-containing therapy, and in treatment naïve patients 
with advanced or metastatic UC, who are ineligible for cisplatin-containing chemotherapy for 
their advanced disease.
Approximately 40 patients will be enrolled in each tumor cohort, NSCLC and UC. 
Study Treatment
Avelumab 800 mg fixed dose will be administered as a 1-hour (hr) intravenous (IV) infusion 
every 2 weeks (Q2W), on Day 1 and Day 15 of each 28 day cycle.

Page 12
Axitinib will be administered at 5 mg by mouth (PO) twice daily (BID), with or without 
food, on a continuous dosing schedule (see Section 5.5.2).
Treatment with study drugs may continue until confirmed disease progression, patient 
refusal, patient lost to follow up, unacceptable toxicity, or the study is terminated by the
sponsor, whichever comes first (see Section 6.3).
Patients who develop disease progression on study treatment but are otherwise continuing to 
derive clinical benefit from study treatment will be eligible to continue with avelumab 
combined with axitinib, single-agent avelumab, or single-agent axitinib provided that the 
treating physician has determined that the benefit/risk for doing so is favorable.
Statistical Methods
The primary objective is to assess the ORR of avelumab in combination with axitinib in 
patients with advanced or metastatic NSCLC who have received at least one prior 
platinum-containing therapy and in treatment naïve patients with advanced or metastatic UC, 
who are ineligible for cisplatin-containing chemotherapy for their advanced disease.  The 
primary endpoint is confirmed OR, which is defined as a complete response (CR) or partial 
response (PR) per RECIST v1.1 by Investigator from the first dose of study treatment until 
disease progression (PD) or death due to any cause.  Both CR and PR must be confirmed by 
repeat assessments performed no less than 4 weeks after the criteria for response are first 
met.  ORR is defined as the proportion of treated patients with confirmed CR or PR per 
Investigator’s assessment according to RECIST v1.1. 
Approximately 40 patients will be enrolled from each of 2 tumor type cohorts: NSCLC and 
UC.  Thus, a total of approximately 80 patients will be enrolled. 
With 40 treated patients per tumor type cohort, ORR can be estimated with a maximum 
standard error of 0.079.  Further, assuming beta (0.5, 0.5) prior:

NSCLC cohort: if 15 responders (out of 40 patients, ORR of 37.5%) are observed, the 
probability of a true ORR 30% (considered a clinically relevant effect above 
single-agent checkpoint inhibition,39-43 [Section 1.2.2]) will be 80% (85.0%).

UC cohort: if 19 responders (out of 40 patients, ORR of 47.5%) are observed, the 
probability of a true response rate 40% (considered a clinically relevant effect above 
single-agent checkpoint inhibition,25,26 [Section 1.2.1]) will be 80% (83.4%).

1. INTRODUCTION
1.1. Mechanism of Action/Indication
The study will investigate avelumab in combination with axitinib in patients with advanced 
or metastatic NSCLC who have received at least one prior platinum-containing therapy, and 
in treatment naïve patients with advanced or metastatic UC, who are ineligible for 
cisplatin-containing chemotherapy for their advanced disease.
The mechanisms of action of each investigational product are described in Section 1.2.3 and 
Section 1.2.4.
1.2. Background and Rationale 
1.2.1. Urothelial Cancer 
UC includes tumors originating from the urothelial cells lining the bladder, renal pelvis,
ureter, and urethra.2  Bladder cancer alone accounts for 90% of UC,2 and is the ninth most
prevalent cancer worldwide, with approximately 430,000 new cases diagnosed and
165,000 deaths attributed to this disease each year.3-5  The incidence and mortality of bladder 
cancer have remained unchanged over the last 24 years.6  Approximately 30% of patients 
with newly diagnosed UC present with muscle-invasive UC of the bladder,7 a high-grade,
typically aggressive disease requiring multimodal therapy including radical cystectomy and 
chemotherapy.2,8,9  Metastatic disease is observed in 5% of patients at the time of diagnosis;8
those patients who are diagnosed with localized muscle invasive tumor and treated with 
radical cystectomy alone usually develop metastatic disease within 2 years of the initial 
diagnosis.10,11
Combination chemotherapy with cisplatin-based regimens is the standard of care for first-line 
locally advanced or metastatic UC.12-16  However, up to 50% of patients are ineligible or 
“unfit” to receive cisplatin due to age- or disease-associated renal dysfunction, poor 
performance status or other existing co-morbidities such as hearing loss, neuropathy and 
heart failure.17-19  Standard treatment options for these treatment naïve, cisplatin-ineligible 
patients have included carboplatin-based regimens20 and single- or double-agent 
chemotherapy depending on patient presentation and performance status.21,22  While no direct 
comparison of cisplatin- versus carboplatin-based regimens has been conducted, only 
cisplatin containing regimens have shown survival benefit in patients with advanced or 
metastatic UC.14-16,23,24  Cisplatin-based regimens have a median OS of 14-15 months15,16
while gemcitabine plus carboplatin is associated with a median OS of 9 months and 21% 
treatment discontinuation due to treatment-related toxicity.20  Consequently, due to the 
survival differences of the platinum-based regimens, there is an unmet medical need for 
improvements in clinical efficacy and treatment tolerability in cisplatin-ineligible for patients 
with advanced or metastatic UC.

Blocking the PD-1/PD-L1 pathway has shown therapeutic benefit for many tumor types, 
including UC. Remarkable breakthroughs in second-line systemic treatment have led to the 
approvals of five immune checkpoint (PD-1/PD-L1) inhibitors, including avelumab 
(Bavencio®), in the US and Europe (EU) for single agent use in patients with UC who have 
progressed during or following platinum-containing chemotherapy or progressed within 
12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.2  
 
 
 
  Please see 
Section 1.2.3.3 for detailed data with avelumab in patients with metastatic or locally 
advanced UC, who have progressed during or following platinum-containing chemotherapy 
or progressed within 12 months of neoadjuvant or adjuvant treatment with 
platinum-containing chemotherapy.
Furthermore, two immune checkpoint inhibitors, atezolizumab, PD-L1 mAb, (Tecentriq®) 
and pembrolizumab, PD-1 mAb, (Keytruda®), gained approval in the US and EU as 
single-agent, first-line therapy options for cisplatin-ineligible patients with advanced or 
metastatic UC.25,26  Results from the IMvigor 210 cohort 1 (N=119 treated), a single-arm, 
Phase 2 study testing the safety and efficacy of atezolizumab monotherapy in patients with 
cisplatin-ineligible UC, showed an ORR of 23% (95% CI: 16-31%) and median OS of 
15.6 months (95% CI: 10.4 months to not estimable).26  The most common treatment-related 
AEs were fatigue (30%), diarrhea (12%) and pruritus (11%).  In another Phase 2, single-arm 
study (KEYNOTE-052, N=370 treated), pembrolizumab monotherapy also showed 
anti-tumor activity and acceptable safety in patients with treatment naïve, cisplatin-ineligible 
UC.25  ORR was 24% (95% CI: 20-29%) and 6 month OS rate was 67% (95% CI: 62-73%).  
Common treatment-related AEs included fatigue (15%), pruritus (14%) and rash (9%). 
VEGF blockade has been extensively studied in first- and second-line UC.27  To date, 
monotherapy studies, including tyrosine kinase inhibitors (TKIs) sunitinib, pazopanib and 
sorafenib as well as aflibercept, an antibody-based VEGF recombinant fusion protein, have 
not shown single-agent clinical activity.27  Combination studies with chemotherapy have 
been more encouraging though toxicity and tolerability concerns have adversely impacted 
risk/benefit considerations.  Bevacizumab in combination with cisplatin- and 
carboplatin-based regimens both demonstrated impressive efficacy with median OS of 
19.1 months and 13.9 months, respectively.28,29  However, significant Grade ≥3 hematologic 
treatment-related toxicity in addition to vascular thrombotic events (VTE) were noted in both 
studies.  Likewise, sunitinib in combination with cisplatin plus gemcitabine showed ORR 
ranging from 49 to 64% but was also poorly tolerated.30,31  Conversely, pazopanib plus 
paclitaxel was studied in a heavily pretreated patient population (N=28 evaluable patients) 
where ORR was 54% (95% CI: 33.9-72.5%) with median PFS of 6.2 months and median OS 
10.0 months and was generally well-tolerated.32  The most common Grade ≥3 AEs were 
fatigue (13%) and anemia (13%).  Most recently, results from the Phase 3 study (RANGE) 
testing ramucirumab, a vascular endothelial growth factor receptor-2 (VEGFR-2) antibody, 
plus docetaxel compared to placebo plus docetaxel in previously treated patients with UC 
were reported by Petrylak et al at the European Society for Medical Oncology (ESMO)

2017 annual meeting.  A statistically significant improvement was observed for PFS, median 
4.07 months vs 2.76 months, respectively, (hazard ratio [HR]=0.757, 95% CI: 0.607–0.943, 
p=0.0118), thus potentially providing another therapy option for second-line UC.33
1.2.2. NSCLC
NSCLC is the most common cause of fatal malignancy globally, most often diagnosed in 
advanced stages, where surgery and local radiotherapy are no longer curative.5,34  Standard 
therapy in later stages of disease is primarily palliative in nature, involving the use of 
cytotoxic chemotherapy with or without radiation therapy or immunotherapy.35,36  Targeted 
therapies such as TKIs may be used for appropriate patients.  In spite of these treatments, 
5-year survival is only about 17.0% for advanced-stage NSCLC patients, highlighting the 
need for novel therapies and treatment regimens.37
Single-agent chemotherapy has been the standard of care for second- and third-line therapy 
for patients with advanced NSCLC in whom prior platinum-based therapy failed.37,38  
However, a new treatment paradigm has emerged based on five randomized studies that 
evaluated immune checkpoint inhibitor monotherapy compared to single-agent 
chemotherapy.39-43  Results across these studies consistently demonstrated clinically 
meaningful improvements in OS with medians ranging from 9.2 to 13.8 months for 
checkpoint inhibitors versus 6.0 to 9.6 for chemotherapy.39-43  ORR ranged from 14% to 
20% and importantly, extended duration of response was observed varying from 
14.3 -17.2 months to not reached (NR) compared to 5.6 to 8.4 months for chemotherapy.  
Efficacy was independent of PD-L1 expression though trends toward greater benefit were 
seen among higher levels of PD-L1 expression.  Both squamous and nonsquamous 
histologies derived clinical benefit.  Safety profiles were consistent among the trials with low 
grade (Grade 1 or 2) fatigue, nausea and decreased appetite being the most commonly 
reported AEs.39-43  In addition, substantially fewer treatment-related Grade 3 AEs and 
treatment-related discontinuations were reported, indicating single agent checkpoint 
inhibitors are generally well tolerated and the AE profile is quite different compared with 
chemotherapy.  Indeed, a recent updated 2-year safety and survival analysis from the 
CHECKMATE 017 and 057 studies showed long-term benefit with nivolumab compared to 
docetaxel in squamous cell histology, 2-year OS rate of 23% (95% CI, 16-30%) versus 
8% (95% CI, 4-13%) and nonsquamous histology, 2-year OS rate of 29% (95% CI, 24-34%) 
versus 16% (95% CI, 12-20%).44  No new safety signals were identified. 
Anti-angiogenic therapy has demonstrated anti-tumor activity in advanced NSCLC.  
Bevacizumab (Avastin), a mAb targeting VEGF, was the first approved anti-angiogenic 
agent in advanced NSCLC for front-line therapy in combination with chemotherapy based on 
the Eastern Cooperative Oncology Group (ECOG) 4599 trial which compared bevacizumab 
plus paclitaxel/carboplatin vs paclitaxel/carboplatin alone in treatment naïve patients with 
nonsquamous histology.45  Significant improvements in PFS (median 6.2 months vs 
4.5 months, HR= 0.66, p<0.001), response rate (RR) (35% vs 15%, p<0.001) and OS 
(median 12.3 months vs 10.3 months, HR= 0.79, p=0.003) were observed in the bevacizumab 
arm versus chemotherapy arm.  The experimental regimen was well-tolerated though higher 
rates of Grade 3 bleeding were observed in the bevacizumab arm compared to the

chemotherapy doublet, (4.4% vs 0.7%, p<0.001).  Subset analyses from an earlier Phase 2 
study with bevacizumab plus paclitaxel/carboplatin identified clinical features such as 
squamous histology, cavitary tumors and centrally located tumors with close proximity to 
major blood vessels as risk factors for life-threatening bleeding and as a result, were 
excluded in later bevacizumab trials.46  Ramucirumab (Cyramza), a mAb targeting 
VEGRF-2, was recently approved in combination with docetaxel for second-line treatment of 
NSCLC based on results from the REVEL study.47  In this Phase 3, randomized, 
double-blind study, ramucirumab plus docetaxel was compared to docetaxel/placebo in 
patients who progressed during or after a platinum-doublet regimen; both squamous and 
nonsquamous histologies were included.  Median OS in the ramucirumab arm was 
10.5 months versus 9.1 months for the placebo arm (HR, 0.86; 95% CI: 0.75-0.98; 
p=0.023).47  The most common Grade 3 AEs were hypertension, fatigue and hematologic 
neutropenia, febrile neutropenia and leukopenia.  Though the ramucirumab arm had more 
bleeding/hemorrhage events of any grade compared to the placebo arm (29% vs 15%), the 
number of Grade 3 events were the same in both arms. 
Recent data also demonstrated anti-tumor activity of anti-angiogenic TKIs in patients with 
advanced NSCLC.48  In a Phase 3 (LUME-Lung1), randomized, double-blind study, 
nintedanib, a multi-kinase TKI with anti-VEGFR-2, fibroblast growth factor receptor (FGFR) 
and platelet-derived growth factor receptor (PDGFR) and activity, was evaluated in 
combination with docetaxel compared to placebo/docetaxel in second-line patients with 
advanced NSCLC.49  PFS, the primary endpoint, was significantly improved in the 
nintedanib arm compared to the placebo arm, median 3.4 months versus 2.7 months 
(HR=0.79, 95% CI: 0.68-0.92, p=0.019).  In pre-specified sub-group analyses, OS was 
significantly improved in the nintedanib combination for all patients with adenocarcinoma 
histology compared to placebo, median 12.6 months versus 10.3 months (HR=0.83, 
95% CI: 0.70-0.99, p=0.0359) and for patients with adenocarcinoma who progressed within 
9 months after starting first-line treatment, median 10.9 months compared to 7.9 months 
(HR=0.75, 95% CI: 0.60-0.92, p=0.0073).49  
Clinical experience with axitinib in NSCLC is described in Section 1.2.5.
1.2.3. Avelumab (BAVENCIO, MSB0010718C)
Avelumab (MSB0010718C) is a human Ig G1 mAb directed against PD-L1.  Avelumab 
selectively binds to PD-L1 and competitively blocks its interaction with PD-1, thereby 
interfering with this key immune checkpoint inhibition pathway.  For complete details of the 
in vitro and nonclinical studies, refer to the avelumab Investigator’s Brochure (IB).50
1.2.3.1. Avelumab Clinical Experience
Avelumab is being developed jointly by Pfizer and Merck KGaA/EMD Serono, and is being 
studied in Phase 1, 2, and 3 clinical protocols in a variety of adult cancers, including NSCLC, 
gastric cancer, Merkel cell carcinoma (MCC), renal cell carcinoma (RCC), ovarian cancer, 
UC, head and neck cancer, classic Hodgkin’s Lymphoma and non-Hodgkin’s Lymphoma, as 
single agent or in combination with chemotherapy, TKIs, or other immune-modulating 
agents.

On 23 March 2017, avelumab received accelerated approval from the FDA for the treatment 
of adults and pediatric patients 12 years and older with metastatic MCC, including those who 
have not received prior chemotherapy.  In addition, on 09 May 2017, avelumab was also 
approved by the FDA for the treatment of patients with locally advanced or metastatic 
urothelial carcinoma who experience disease progression during or after platinum-containing 
chemotherapy, or who experience disease progression with 12 months of neoadjuvant or 
adjuvant treatment with platinum-containing chemotherapy.

1.2.3.4. Pharmacokinetics of Avelumab Fixed Dosing 
To date, avelumab has been administered at the clinically active, safe, and tolerable dose of 
10 mg/kg every 2 weeks (Q2W) to more than 1700 patients across multiple indications.  
Avelumab was originally dosed on a mg/kg basis in order to reduce inter-subject variability 
in drug exposure.  However, emerging data for monoclonal antibodies, including the 
marketed PD-1 and PD-L1 immune checkpoint inhibitors nivolumab, pembrolizumab and 
atezolizumab, reveal that body weight-based dosing regimens do not result in less variability 
in measures of exposure over fixed (ie, body-weight independent) dosing regimens.53-55  
Additionally, fixed dosing offers the advantages of less potential for dispensing errors, 
shorter dose preparation times in a clinical setting, and greater ease of administration.
Population pharmacokinetic (PK) analysis was conducted based on the acquired data across 
3 single-agent avelumab studies in 1827 patients with 14 different types of cancer.  PK 
simulations suggest that exposures to avelumab across the available range of body weights 
are similar, less variable with 800 mg Q2W compared with 10 mg/kg Q2W; exposures were 
similar near the population median weight.  Low-weight subjects tended toward marginally 
lower exposures relative to the rest of the population when weight-based dosing was used, 
and marginally higher exposures when fixed dosing was applied.  However, the implications 
of these exposure differences are not expected to be clinically meaningful at any weight 
across the whole population.  Furthermore, the 800 mg Q2W dosing regimen is expected to 
result in Ctrough >1 μg/mL required to maintain avelumab serum concentrations at 
>90% target occupancy (TO) throughout the entire Q2W dosing interval in all weight 
categories.
Therefore, in this clinical trial, a fixed dosing regimen of 800 mg administered as a 1-hour IV 
(-10 min/+20 min) infusion will be utilized for avelumab on Days 1 and 15 of each cycle. 
Complete information for avelumab may be found in the SRSD, which for this study is the 
avelumab IB.50

1.2.4. Axitinib (INLYTA, AG 013736)
One of the investigational products in the present clinical trial is axitinib (INLYTA, 
AG 013736), an oral, small molecule, TKI selective for VEGFRs 1, 2, and 3, approved 
multinationally for the treatment of advanced RCC after failure of one prior systemic therapy 
(actual indication varies according to region/country).56
Axitinib is an adenosine triphosphate (ATP) competitive inhibitor that binds to the 
unphosphorylated (non-activated) “DFG-out” conformation of the catalytic domain of a 
receptor tyrosine kinase.  In enzymatic assays, axitinib was found to be highly potent 
(Ki = 28 picomolar) against the kinase activity of juxta membrane (JM) domain containing 
human VEGFR 2 recombinant protein.  In additional kinase assays, axitinib showed potent 
and ATP competitive inhibition of the VEGFRs 1, 2, and 3 and PDGFR-, but not other 
closely related family kinases.  Receptor binding studies and cell based assays confirmed that 
axitinib is a potent and selective inhibitor of VEGFRs 1, 2, and 3.  Axitinib was shown to 
have antiangiogenic activity in a number of models including spontaneous pancreatic islet 
cell tumors of RIP-TAG2 transgenic mice model and demonstrated anti-tumor efficacy 
including marked cytoreductive anti-tumor activity in multiple tumor models implanted in 
athymic mice.
Overall, the adverse events reported for axitinib in clinical studies were considered generally 
tolerable and manageable.  For single agent axitinib, the most common adverse events 
(>20% of patients) reported from 1445 cancer patients regardless of causality included 
diarrhea, hypertension, decrease appetite, nausea, weight decreased, dysphonia, 
palmar-plantar erythrodysaesthesia syndrome, hypothyroidism, and proteinuria.  
Grade 3 events that occurred most frequently were hypertension, fatigue, and diarrhea.  
Following twice daily oral administration, axitinib is rapidly absorbed (median Tmax
2.5-4.1 hours).  The plasma half-life of axitinib ranges from 2.5 to 6.1 hours and steady state 
is expected within 2 to 3 days of dosing.  Dosing of axitinib at 5 mg twice daily resulted in 
approximately 1.4 fold accumulation compared to administration of a single dose.  At steady 
state, axitinib exhibits approximately linear pharmacokinetics within the 1 mg to 20 mg dose 
range.  The mean absolute bioavailability of axitinib after an oral 5 mg dose is 58%.  Axitinib 
can be administered with or without food.  Axitinib is metabolized primarily in the liver by 
CYP3A4/5 and to a lesser extent by CYP1A2, CYP2C19, and UGT1A1.  The predominant 
sulfoxide and N-glucuronide metabolites in human plasma show approximately 400 fold 
less in vitro potency against VEGFR 2 compared to axitinib.

1.2.5. Clinical Experience with Axitinib in NSCLC
Axitinib has been evaluated in NSCLC as monotherapy and in combination with platinum-
and taxane-based regimens.58,59  In Schiller et al, axitinib single-agent activity was evaluated 
in a Phase 2, open-label study among 32 patients with squamous or nonsquamous histology; 
23 patients had received 1 previous systemic therapy.  Axitinib was well-tolerated and 
demonstrated preliminary single-agent activity with an ORR of 9%, a disease control rate of 
41% and median OS of 14.8 months (95% CI: 10. 7 months-not estimable).59  The most 
common treatment-related events were fatigue, anorexia, diarrhea, nausea and hypertension.  
In a Phase 1 dose escalation study, axitinib at 5 mg BID was examined in combination with 
cisplatin- and carboplatin-based regimens among patients with advanced solid tumors.  A 
total of 17 patients with NSCLC, including a squamous cell expansion cohort, received the 
axitinib plus carboplatin-based regimen; objective responses were observed in 5 patients with 
NSCLC.58  No Grade 3 events of hemoptysis were noted.
In a Phase 2, open-label, single-arm study, 38 first-line patients with squamous cell NSCLC 
were treated with six cycles of axitinib plus cisplatin-based regimen and continued on 
maintenance axitinib monotherapy.60  ORR was 39.5% and median OS was 14.2 months.  
The most frequent Grade 3 AEs were hypertension, neutropenia, fatigue and anemia.  
Pulmonary hemorrhage was observed in 3 patients including one Grade 5 event. 
In another Phase 2 study, 170 treatment naïve patients with nonsquamous cell NSCLC were 
randomized to receive axitinib/pemetrexed/cisplatin, modified axitinib 
dosing/pemetrexed/cisplatin or pemetrexed/cisplatin alone.61  Although axitinib arms did not 
show a statistically significant difference in ORR, it was numerically higher in the axitinib 
arms compared to chemotherapy alone, 45.5% for the standard axitinib arm, 39.7% in the 
modified axitinib dosing arm and 26.3% for the pemetrexed/cisplatin arm; median OS was 
17.0 months, 14.7 months and 15.9 months, respectively.  Gastrointestinal AEs (vomiting, 
nausea), fatigue and neutropenia were common among all treatment arms.  
Grade 3 hypertension was observed in the axitinib arms and Grade 3 fatigue in the 
chemotherapy alone arm. 
1.2.6. Clinical Experience of Combination Therapy of Avelumab Plus Axitinib
Study B9991002 is a Phase 1b, open-label, multicenter, multiple-dose trial of the 
combination of avelumab with axitinib in treatment-naïve patients with aRCC.  A 
dose-finding phase preceded the dose-expansion phase of the trial.  The study objectives 
were to identify a tolerable dose of the combination for further studies, to evaluate the 
anti-tumor activity of the combination, and to investigate candidate predictive biomarkers 
(ClinicalTrials.gov Identifier: NCT02493751).  One regimen was evaluated in the 
dose-finding phase (a 7-day lead-in period with axitinib 5 mg oral twice daily (BID) followed 
by avelumab 10 mg/kg intravenously (IV) Q2W in combination with axitinib 5 mg oral 
BID).  The maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) 
were determined to be avelumab 10 mg/kg IV Q2W with axitinib 5 mg oral BID.  In the dose 
expansion phase, both a 7-day lead in period with axitinib 5 mg oral BID followed by 
avelumab 10 mg/kg IV Q2W in combination with axitinib 5 mg oral BID (10 patients) and 
avelumab 10 mg/kg IV Q2W in combination with axitinib 5 mg oral BID (39 patients) were

evaluated.  No differences in safety and efficacy were apparent when reviewing the data from 
the 16 patients who received lead-in axitinib (6 patients in the dose-finding cohort and 
10 patients in the dose expansion cohort) and the 39 patients in the dose-expansion cohort 
who did not receive axitinib lead-in; data from both cohorts were therefore analyzed together. 
As of 13 April 2017, per the investigator’s assessment of response according to 
RECIST v.1.1, 32/55 (58.2%) patients had a confirmed objective response 
(95% CI: 44.1-71.3).  A total of 3/55 (5.5%) patients developed a CR, 29/55 (52.7%) patients 
had a PR, and 11/55 (20%) patients had stable disease (SD) as best overall response (BOR).  
An objective response of SD or better (disease control) was achieved in 43/55 (78.2%) 
patients.  Response occurred at the time of the first tumor assessment in 20/32 patients and, at 
the data cut-off date, responses were ongoing in 24/32 patients.  The probability of an 
ongoing response (ie, no disease progression or death) at 12 months was 75.0% 
(95% CI: 54.3–87.3).  A total of 45/54 (83%) patients experienced tumor shrinkage (1 patient 
died prior to the first oncologic assessment).
The most frequent treatment-related adverse events (TRAEs), ie, those reported for 20% of 
patients, and any Grade 5 TRAEs are shown in Table 1.  A total of 32 (58.2%) patients had a 
TRAE of Grade 3 severity: 26 (47.3%) patients had Grade 3 TRAEs, 5 (9.1%) patients had 
a Grade 4 TRAE, and 1 (1.8%) patient had a Grade 5 TRAE (myocarditis).  The autopsy of 
the patient with a Grade 5 TRAE indicated immune myocarditis.

In conclusion, for this patient population, the safety profile of the combination was tolerable, 
manageable, and consistent with the known safety profiles of avelumab50 and axitinib57 when 
administered as monotherapy.
This combination is being evaluated in the Phase 3 study B9991003 (NCT02684006): A 
Study of Avelumab With Axitinib Versus Sunitinib In Advanced Renal Cell Cancer 
(JAVELIN Renal 101).
1.2.7. Study Rationale for Tumor Types Under Evaluation 
With evolving data it is becoming evident that combination immunotherapy strategies will be 
necessary to achieve enhanced anti-tumor activity for patients who do not experience disease 
control with single-agent immune checkpoint inhibitors.1 Growing nonclinical and clinical 
evidence suggest that the combination of checkpoint inhibition plus antiangiogenic agents 
may potentially improve anti-tumor activity and patient outcomes compared to results seen 
with single agents. VEGF can exert immunosuppressive effects in tumors by inhibiting 
maturation of dendritic cells, promoting immune suppressive cell infiltration and enhancing 
immune checkpoint molecule expression.62  Likewise, immunosuppressive cells such as 
myeloid derived suppressor cells secrete pro-angiogenic factors VEGF and MMP which 
directly promote angiogenesis growth63 and induce resistance to anti-VEGF therapy.  Given 
the immunomodulatory and anti-angiogenic properties of anti-VEGF therapies, including

Page 29
axitinib,62-66 potential synergy with anti-VEGF therapy in combination with immune 
checkpoint blockade may increase clinical efficacy in patients with advanced or metastatic 
NSCLC who have received at least one prior platinum-containing therapy and in treatment 
naïve patients with advanced or metastatic UC, who are ineligible for cisplatin-containing 
chemotherapy for their advanced disease.
The two tumor types selected for the study are responsive to monotherapy checkpoint 
inhibition which is available as standard-of-care for these indications.  In addition, avelumab 
has shown preliminary evidence of clinical activity as monotherapy in these tumor types 
(NSCLC51 and UC67); see Section 1.2.3.2 and Section 1.2.3.3 respectively).  Furthermore, 
NSCLC and UC have demonstrated sensitivity to anti-VEGFR-2 inhibition in combination 
with chemotherapy.33,45,47,49  However, despite these therapies, substantial clinical unmet 
needs exist as the majority of patients experience disease progression during the course of 
their treatment.
Recently, cabozantinib, a multi-kinase TKI for VEGFR2, mesenchymal-epithelial transition
factor (MET) and AXL, in combination with nivolumab ± ipilumumab showed preliminary 
anti-tumor activity and a manageable safety profile in heavily pretreated, advanced 
genitourinary (GU) malignancies.68  ORR for evaluable patients was 33% with a median PFS 
of 5.9 months (95% CI: 4.5-10.1 months) and median OS of 20 months 
(95% CI: 10.6 months-undefined).  Of the 42 patients treated, 15 patients (13 evaluable) with 
advanced UC demonstrated an ORR of 38%.68  Other ongoing anti-VEGF plus immune 
checkpoint combination trials include ramucirumab plus pembrolizumab which is being 
evaluated in multiple tumor cohorts including second-line UC and previously treated 
NSCLC.  In the UC cohort, preliminary results for 24 treated patients showed anti-tumor 
activity with a RR of 8% and SD of 42%; median PFS was 1.87 months 
(95% CI: 1.28-3.38 months).69  Among 27 patients in the NSCLC cohort, ORR was 30%, 
median PFS was 9.7 months (95% CI: 4.6-11.5 months) and the OS rate at 6 months was 
84.9%.70  There were no new safety signals for either cohort. 
1.2.8. Summary of Benefit/Risk Assessment
An evaluation of the anticipated benefits and risks as required in Article 3(2)(a) of Directive 
2001/20/EC (cf. Article 6(3)(b) of Directive 2001/20/EC) has been conducted.
The benefit-risk relationship has been carefully considered in the planning of this trial.  
Avelumab demonstrated clinical activity in patients with advanced solid tumors, including 
NSCLC (first-line and second-line or higher), breast cancer, CRPC, UC and ovarian cancer
 
 
 
  Infusion-related reactions, 
including hypersensitivity and irAEs/autoimmune disorders, have been identified as 
important risks for avelumab.  Respective risk mitigation measures have been implemented 
in all ongoing clinical studies with avelumab, including this clinical trial protocol.  These

include guidelines for treatment interruption and discontinuation in case of irAEs, as well as 
mandatory pre-treatment with an antihistamine and acetaminophen prior to the first 
4 avelumab infusions (Cycles 1-2) and as clinically indicated thereafter.
Thus far, avelumab has demonstrated a manageable safety profile and significant anti-tumor 
activity in various tumor types.50
Axitinib is approved multi-nationally for the treatment of advanced RCC after failure of one 
prior systemic therapy.  The adverse events reported for axitinib are well characterized in 
clinical studies and considered tolerable and manageable (see Section 1.2.4).  Furthermore, 
axitinib demonstrated acceptable toxicity profile as a monotherapy or in combination with 
other agents. 
The combination of avelumab with axitinib is currently being tested in study B9991002, as 
described in Section 1.2.6.  Overall, the safety profile of the combination appears 
manageable and in line with that of individual agents.  One case of fatal myocarditis has 
occurred in a patient after 19 days of treatment with the combination and 5 days after the 
second dose of avelumab.  
 
 
 
 
  
Severe or fatal myocarditis has also been reported in literature with pembrolizumab 
single-agent,71,72 nivolumab single-agent,73 nivolumab in combination with ipilimumab,74
and ipilimumab single-agent,75 either as single adverse events or in the context of more 
complex autoimmume syndromes.  For ipilimumab, myocarditis (including with fatal 
outcome) is reported in the prescribing information with a frequency <1%.76  Guidelines 
about the management of suspect or confirmed cases of myocarditis and relevant avelumab 
management instructions have been included in Table 6.
This combination is being evaluated in the Phase 3 Study B9991003 (NCT02684006): A 
Study of Avelumab With Axitinib Versus Sunitinib In Advanced Renal Cell Cancer 
(JAVELIN Renal 101).
Based on the manageable safety profiles of avelumab and axitinib and its’ enhanced 
anti-tumor activity in advanced RCC, the anticipated benefit-risk relationship of avelumab 
given in combination with axitinib is expected to be favorable for investigation in patients 
with advanced or metastatic NSCLC who have received at least one prior 
platinum-containing therapy, and in treatment naïve patients with advanced or metastatic UC, 
who are ineligible for cisplatin-containing chemotherapy for their advanced disease.

3. STUDY DESIGN
This is an open-label, multi-center, Phase 2 study to evaluate the safety and efficacy of 
avelumab in combination with axitinib in patients with advanced or metastatic NSCLC who 
have received at least one prior platinum-containing therapy, and in patients with advanced 
or metastatic UC, who are treatment naïve and ineligible for cisplatin-containing 
chemotherapy for their advanced disease.
Approximately 40 patients will be enrolled in each cohort, NSCLC and UC.  See Figure 1. 
Figure 1.
Study Schema
Patients will receive avelumab 800 mg IV Q2W on Days 1 and 15 of each 28 day cycle in 
combination with axitinib 5 mg PO BID on a continuous dosing schedule.  Treatment with 
study drugs may continue until confirmed disease progression, patient refusal, patient lost to 
follow up, unacceptable toxicity, or the study is terminated by the sponsor, whichever comes 
first (see Section 6.3).
Patients who develop disease progression on study treatment but are otherwise continuing to 
derive clinical benefit from study treatment will be eligible to continue with avelumab 
combined with axitinib, single-agent avelumab, or single-agent axitinib provided that the 
treating physician has determined that the benefit/risk for doing so is favorable.

4.3. Lifestyle Requirements 
4.3.1. Contraception
In this study, fertile male patients and female patients who are of childbearing potential as 
applicable to the study will receive avelumab for which the teratogenic risk is currently 
unknown in combination with axitinib, which has been associated with demonstrated 
teratogenicity.  Patients who are, in the opinion of the investigator, sexually active and at risk 
for pregnancy with their partner(s) must agree to use 2 methods of contraception (at least one 
of which is considered to be highly effective with low user dependency as defined below) 
throughout the study and for at least 30 days after the last dose of avelumab (90 days for 
male patients) and 90 days after the last dose of axitinib.  The investigator or his or her 
designee, in consultation with the patient, will confirm that the patient has selected 
2 appropriate methods of contraception (at least one of which is considered to be highly 
effective with low user dependency as defined below) for the individual patient and his/her 
partner(s) and will confirm that the patient has been instructed in their consistent and correct 
use.  At time points indicated in the Schedule of Activities, the investigator or designee will 
inform the patient of the need to use 2 methods of contraception consistently and correctly 
and document the conversation, and the patient’s affirmation, in the patient’s chart.  In 
addition, the investigator or designee will instruct the patient to call immediately if 1 or both 
of the selected contraception methods is discontinued or if pregnancy is known or suspected 
in the patient or partner.
Highly effective methods of contraception with low user dependency include (applies to 
female patients at risk for pregnancy with their male partners):
1. Established use of hormonal methods of contraception associated with inhibition of 
ovulation (eg, inserted, injected, implanted), provided the patient or male patient’s 
female partner plans to remain on the same treatment throughout the entire study and 
has been using that hormonal contraceptive for an adequate period of time to ensure 
effectiveness.
2. Correctly placed copper-containing intrauterine device (IUD).
3. Male sterilization with absence of sperm in the postvasectomy ejaculate.
4. Bilateral tubal ligation/bilateral salpingectomy or bilateral tubal occlusive procedure
(provided that occlusion has been confirmed in accordance with the device’s label).
4.4. Sponsor’s Qualified Medical Personnel
The contact information for the sponsor's appropriately qualified medical personnel for the 
study is documented in the study contact list located in the Study Manual. 
To facilitate access to appropriately qualified medical personnel on study-related medical 
questions or problems, patients are provided with a contact card.  The contact card contains, 
at a minimum, protocol and investigational product identifiers, patient study numbers, 
contact information for the investigator site, and contact details for a contact center in the 

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 41
event that the investigator site staff cannot be reached to provide advice on a medical 
question or problem originating from another healthcare professional not involved in the 
patient’s participation in the study.  The contact number can also be used by investigator staff 
if they are seeking advice on medical questions or problems; however, it should be used only 
in the event that the established communication pathways between the investigator site and 
the study team are not available.  It is therefore intended to augment, but not replace, the 
established communication pathways between the investigator site and the study team for 
advice on medical questions or problems that may arise during the study.  The contact 
number is not intended for use by the patient directly, and if a patient calls that number, he or 
she will be directed back to the investigator site.
5. STUDY TREATMENTS
For the purposes of this study, and per International Conference on Harmonisation (ICH) 
guidelines, investigational product is defined as a pharmaceutical form of an active 
ingredient or placebo being tested or used as a reference/comparator in a clinical trial, 
including a product with a marketing authorization when used or assembled (formulated or 
packaged) in a way different from the approved form, or when used for an unapproved 
indication, or when used to gain further information about an approved use (ICH E6 1.33).  
For this study, the investigational products are avelumab and axitinib.
5.1. Allocation to Treatment
At the time that a patient has signed informed consent and entered screening, the site should 
contact the interactive response technology (IRT) system to obtain the patient identification 
number. 
Once a patient has met all eligibility criteria, assignment of patient enrollment number, 
patient enrollment, and allocation of investigational product will be managed by the IRT 
system.  The site will need to contact the IRT system to enroll the patient and to obtain the 
study drug allocation information.  At the time of enrollment, site personnel (study 
coordinator or specified designee) will be required to enter into or select information from 
the IRT system including, but not limited to, the user’s identification and password, the 
protocol number, and the patient enrollment number.  The IRT system will then provide a 
treatment assignment and dispensable unit (DU) or vial or bottle number for each 
investigational product to be dispensed.  The IRT system will also provide a confirmation 
report containing the patient number and DU or vial or bottle numbers assigned.  The 
confirmation report must be stored in the site’s files. 
Study treatment must be initiated preferably on the day of enrollment, but no later than
3 calendar days after enrollment.
There is a 24 hour a day, 365 days a year IRT helpdesk available for any questions or issues.  
The study specific IRT reference manual will provide the contact information and further 
details on the use of the IRT system.

5.2. Treatment Duration
Patients will continue to receive study treatment until objective disease progression assessed 
by investigator (see Section 5.5.3 for guidance on treatment beyond progression), patient 
refusal, unacceptable toxicity, global deterioration of health status requiring discontinuation
or until the study is terminated by the Sponsor, whichever occurs first.
5.3. Patient Compliance
5.3.1. IV Administered Investigational Product
For avelumab, the site will complete the required dosage Preparation Record located in the 
Investigational Product Manual.  The use of the Preparation Record is preferred, but it does 
not preclude the use of an existing appropriate clinical site documentation system.  The 
existing clinical site's documentation system should capture all pertinent /required 
information on the preparation and administration of the dose.  This may be used in place of 
the Preparation Record after approval from the Pfizer monitor. 
The information related to each trial drug administration, including the date, time, and dose 
of study drug, will be recorded on the case report form (CRF).  The Investigator will ensure 
that the information entered into the CRF regarding drug administration is accurate for each 
patient.  Any reason for noncompliance should be documented.
Non-compliance is defined as a patient missing >1 infusion of any investigational product for 
non-medical reasons.  If 1 infusion is missed and the interval between the subsequent 
infusion and the last administered treatment is longer than 4 weeks for nonmedical reasons, 
the criteria of insufficient compliance will have been met as well. 
5.3.2. P.O. Administered Investigational Product
For axitinib, patients will be required to return all unused study treatment at the beginning of 
each cycle.  The number of tablets returned by the patient at the end of the cycle will be 
counted, documented, and recorded for drug accountability.  Treatment compliance (reported 
as a percent) will be defined as the number of tablets taken during the study divided by the 
expected number of tablets multiplied by 100%.  Tablets that are not returned will be 
considered to have been taken unless reported otherwise by the patient.  Drug diary records 
will be provided to the patients as an aid for the recording of study treatment compliance. 
The study site must follow up (for example, via a telephone call) with each patient on 
Cycle 1 Day 5 (3 days) to confirm that the patient understands and is in compliance with 
axitinib dosing instructions.  If needed, the patient will be re-trained.  The same follow-up 
process will be applied in case the dose of axitinib is modified during the treatment period.
5.4. Investigational Product Supplies
Avelumab and axitinib will be supplied for the study by Pfizer Global Clinical Supply, 
Worldwide Research and Development.  Drug supplies will be shipped to the study sites with 
a Drug Shipment and Proof of Receipt form.  This form will be completed, filed, and the 
shipment confirmed as directed on the bottom of the Drug Shipment and Proof of Receipt

them and to the environment should undertake the preparation, handling, and safe disposal of 
investigational agents.
5.4.2.1. Avelumab
Avelumab will be dosed at the investigational site.
The contents of the avelumab vials are sterile and nonpyrogenic, and do not contain 
bacteriostatic preservatives.  Any spills that occur should be cleaned up using the facility’s 
standard cleanup procedures for biologic products.
For application in this trial, avelumab drug product must be diluted with 0.9% saline solution 
(sodium chloride injection).  Detailed information on infusion bags and medical devices to be 
used for the preparation of the dilutions and subsequent administration will be provided in 
the Dosage and Administration Instructions contained in the Investigational Product Manual 
(IP Manual).

Page 44
Any unused portion of the solution should be discarded in biohazard waste disposal with 
final disposal by accepted local and national standards of incineration.
See the Dosage and Administration Instructions in the IP Manual for instructions on how to 
prepare the investigational product for administration.  Investigational product should be 
prepared and dispensed by an appropriately qualified and experienced member of the study 
staff (eg, physician, nurse, physician’s assistant, practitioner, or pharmacist) as allowed by 
local, state, and institutional guidance.
5.4.2.2. Axitinib
Axitinib is a hazardous drug (due to possible reproductive toxicity), and should be handled 
according to the recommended procedures described in the current edition of the American 
Society of Hospital Pharmacists (ASHP), Technical Assistance Bulletin on Handling 
Cytotoxic and Hazardous Drugs, American Hospital Formulary Service (AHFS) Drug 
Information (1999) and its references.  Procedures described in each institution’s pharmacy 
or hospital standard operating procedure manual should be followed when handling 
hazardous drugs.
Axitinib will be provided in quantities appropriate for the study visit schedule.  A qualified 
staff member will provide the study treatment via a unique container number using the IRT 
system.
Axitinib will be dispensed on Day 1 of each cycle or as otherwise indicated.  Patients should 
be instructed to keep their study treatment in the bottles provided and not transfer it to any 
other container.  In the event of dose modification, a request should be made of the patient to 
return all previously dispensed study treatment to the clinic.
5.5. Administration
All investigational products will be administered on an outpatient basis.
5.5.1. Avelumab
The Drug Administration Instructions within the IP Manual contains specific instructions for 
avelumab dose calculation, reconstitution, preparation of the infusion fluid, and 
administration.
Avelumab will be administered Q2W on Days 1 and 15 of each 28 day cycle after all 
procedures/assessments have been completed as described in the Schedule of Activities table.  
After Cycle 1, Day 1, avelumab may be administered up to 3 days before or after the 
scheduled Days 1 and 15 of each dose.
Avelumab will be administered as an 800 mg fixed dose via a 1-hour infusion.  Sites should 
make every effort to target infusion timing to be as close to 1 hour as possible.  However, 
given the variability of infusion pumps from site to site, time windows of -10 minutes and 
+20 minutes is permitted (ie, infusion time is 60 minutes: -10 min/+20 min).  The exact 
duration of infusion should be recorded in both source documents and CRF.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 45
In order to mitigate avelumab infusion-related reactions, patients must be premedicated 
approximately 30 to 60 minutes prior to the first 4 infusions of avelumab.  Premedication 
should be administered for subsequent avelumab doses based upon clinical judgment and 
presence/severity of prior infusion reactions.  Premedication will include an antihistamine 
(for example, 25-50 mg diphenhydramine IV or oral equivalent), and paracetamol 
(acetaminophen) (eg, 500-650 mg IV or oral equivalent).  This regimen may be modified 
based on local treatment standards and guidelines, as appropriate, provided it does not 
include systemic corticosteroids. 
Avelumab dose reduction for toxicity management is not permitted, however next 
administration may be omitted due to persisting toxicity or treatment may be discontinued as 
described in Table 4 and Section 5.5.5.  Possible modifications of the infusion rate for the 
management of infusion-related reactions related to avelumab are described in 
Section 5.5.5.5.
5.5.2. Axitinib
Axitinib will be administered at 5 mg PO BID, with our without food, at approximately the 
same time in the morning and evening on a continuous dosing schedule, ie, without a break
in dosing in the absence of drug-related toxicity (see Section 5.5.5).  Axitinib tablets are to be 
taken approximately 12 hours apart and may be administered without regard to meals.  
Tablets must not be crushed, split, or dissolved, and patients should be instructed to swallow 
the study medication whole without manipulation or chewing of the medication prior to 
swallowing.
A dosing card will be provided to the patients to provide guidance for the correct use of 
axitinib.
Patients must be instructed that if they miss a dose or vomit any time after taking a dose, they 
must not “make it up” with an extra dose, but instead resume subsequent doses as prescribed.  
Any missed dose may be taken late, up to 3 hours before the next scheduled dose of that day, 
otherwise, it should be skipped and dosing resumed with subsequent doses as prescribed.
Patient must be instructed to record all doses (missed or vomited doses or extra doses) in a 
dosing diary supplied by the site.  If doses are missed or vomited or if an extra dose is taken, 
this must be indicated in the source documents and CRFs.
Patients experiencing toxicity may require treatment adjustment or discontinuation according
to the guidelines specified in Table 3 and Table 4.
5.5.3. Treatment After Initial Evidence of Radiologic Disease Progression
Immunotherapeutic agents such as avelumab may produce anti-tumor effects by potentiating 
endogenous cancer-specific immune responses.  Following immunotherapy, a clinical 
response may occur later than would typically be expected following treatment with a 
cytotoxic agent.  In addition, this response may occur after an initial increase in tumor burden 
or even after the appearance of new lesions. 

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 46
If radiologic imaging shows disease progression, tumor assessment should be repeated 
4 weeks later in order to confirm the observation.  Patients may continue to receive 
avelumab and axitinib at the Investigator’s discretion while waiting for confirmation of PD if
they are clinically stable as defined by the following criteria:

Absence of clinical signs and symptoms (including worsening of laboratory values) 
of disease progression; 

No decline in ECOG performance status; 

Absence of rapid progression of disease by radiographic imaging; 

Absence of progressive tumor at critical anatomical sites (eg, cord compression) 
requiring urgent alternative medical intervention.
Before continuation of treatment after initial PD, the patient must be re-consented via 
informed consent addendum and informed that by continuing to receive the investigational 
products on study, the patient may be foregoing approved therapy with possible clinical 
benefit(s).
If repeat imaging does not confirm PD, treatment with avelumab and axitinib may be 
continued. 
If the repeat imaging confirms PD, patients should discontinue from all investigational 
products.  However, according to the Investigator’s clinical judgment and after discussion 
between the Investigator and the Sponsor, if a patient with evidence of PD is still 
experiencing clinical benefit, the patient may be eligible for continued treatment with axitinib 
and avelumab.  The Investigator’s judgment should be based on the overall benefit-risk 
assessment and the patient’s clinical condition, including performance status, clinical 
symptoms, adverse events, and laboratory data. 
If the patient is subsequently found to have further disease progression either radiologically 
according to RECIST v 1.1 or clinically, then treatment with axitinib and avelumab should be 
permanently discontinued.
5.5.4. Food Requirements
All investigational products may be administered without regard to food but patients must 
avoid foods that are known strong CYP3A4/5 inhibitors (eg, grapefruit juice or 
grapefruit/grapefruit-related citrus fruits [eg, Seville oranges, pomelos]).
5.5.5. Recommended Dose Modifications
Every effort should be made to administer investigational product on the planned dose and 
schedule.

In the event of significant toxicity, dosing may be delayed and/or reduced as described 
below.  In the event of multiple toxicities, dose modification should be based on the worst 
toxicity observed.  Patients are to be instructed to notify investigators at the first occurrence 
of any adverse symptom.  In addition to dose modifications, investigators are encouraged to 
employ best supportive care according to local institutional clinical practices and according 
to the guidance for selected adverse events provided below.
For avelumab, no dose modifications are permitted in this study, but next infusion may be 
omitted based on persisting toxicity, as outlined in Table 4.  Dose modifications of axitinib 
and infusion omissions of avelumab may occur independently for the two drugs and will be 
reported in the CRF.
Available axitinib dose level for intrapatient dose modification is listed in Table 3.
5.5.5.1. Intrapatient Axitinib Dose Escalation and Dose Reduction
Intrapatient axitinib dose escalation is permitted up to 10 mg BID and may occur according 
to the criteria described below. 
Patients who tolerate the current axitinib dose without Grade >2 axitinib-related adverse
events for 2 consecutive weeks have the option to have their axitinib dose increased (one 
dose level increase at a time) as indicated in Table 3 (unless the patient’s blood pressure [BP]
is >150/90 mm Hg or the patient is receiving antihypertensive medication). Particular 
attention should be provided to a patient’s overall safety profile prior to implementing 
intrapatient axitinib dose escalation.

Patients will be monitored closely for toxicity, and axitinib treatment may be adjusted by
dosing interruption with or without dose reduction as indicated in Table 4.  Dosing
interruption and/or dose reduction by 1, and if needed, 2 dose levels (one dose level decrease 
at a time) as indicated in Table 3 will be allowed depending on the type and severity of
toxicity encountered.  Management of patients requiring more than 2 dose reductions of 
axitinib (one dose level decrease at a time) should be discussed with the sponsor’s medical
monitor.
Patients who have undergone dose reduction may also undergo dose re-escalation back to the

5.5.5.2. Management of Axitinib-Related Hypertension
Patients will be issued BP monitoring devices including cuffs (provided by the sponsor) for
home monitoring and instructed to measure their BP at least once daily (before taking the 
morning dose of axitinib).  All BP measurements will be recorded in a diary and brought to 
the nurse or study coordinator at each clinic visit.  Patients should be instructed to contact the 
site immediately for guidance if their systolic blood pressure rises above 150 mm Hg, 
diastolic blood pressure rises above 100 mm Hg, or if they develop symptoms perceived to 
be related to elevated blood pressure (eg, headache, visual disturbances), although a different 
blood pressure threshold for contacting the site may be used according to the investigator’s 
clinical judgment.
Blood pressure should be well-controlled prior to initiating therapy and patients should be 
monitored for hypertension.78,79  To treat an increase in BP, standard antihypertensives in 
accordance to local standard of care may be used except diltiazem (eg, thiazide or 
thiazide-like diuretics, angiotensin II receptor blockers, angiotensin converting-enzyme 
inhibitors, and dihydropyridine (DHP) calcium channel blockers, beta blockers, etc.).78,79
Dose modification for axitinib in case of hypertension is described in Table 4.
5.5.5.3. Axitinib Dose Modifications and Avelumab Infusion Omissions for
Treatment-Related Toxicity
Recommended axitinib dose modifications and avelumab infusion omissions in case of drug
related toxicity are shown in Table 4. The aforementioned guidelines might be further 
modified at the discretion of the sponsor based on the emerging safety profile of the
combination.  The investigator can consider consulting with the sponsor’s medical monitor in 
case of persistent toxicity that would lead to dose modification or treatment discontinuation 
per toxicity treatment guidelines.

5.5.5.4. Special Precautions for Avelumab Administration
As with all monoclonal antibody therapies, there is a risk of allergic reactions including 
anaphylactic shock.  Avelumab should be administered in a setting that allows for immediate 
access to an intensive care unit or equivalent environment and administration of therapy for 
anaphylaxis, such as the ability to implement immediate resuscitation measures. 
If an allergic reaction occurs, the patient must be treated according to the best available 
medical practice. 
In order to mitigate avelumab infusion-related reactions, patients have to be premedicated 
approximately 30 to 60 minutes prior to the first 4 infusions of avelumab.  Premedication 
should be administered for subsequent avelumab doses based upon clinical judgment and 
presence/severity of prior infusion reactions.  Premedication will include an antihistamine 
(for example, 25-50 mg diphenhydramine IV or oral equivalent), and paracetamol 
(acetaminophen) (eg, 500-650 mg, IV or oral equivalent).  This regimen may be modified 
based on local treatment standards and guidelines, as appropriate, however, the prophylactic 
administration of systemic corticosteroids is not permitted.
Following avelumab infusions, patients must be observed for 30 minutes post-infusion for 
potential infusion-related reactions.  Patients should be instructed to report any delayed 
reactions to the investigator immediately.
Treatment recommendations for the management of infusion-related reactions and severe
hypersensitivity reactions are outlined in Section 5.5.5.5 and Table 5, respectively.
Investigators should also monitor patients closely for potential irAEs, which may become 
manifest at any time after the first dose of treatment.  Such events may consist of persistent 
rash, diarrhea and colitis, autoimmune hepatitis, arthritis, glomerulonephritis, 
cardiomyopathy, or uveitis and other inflammatory eye conditions.  However potential irAEs 
can occur in any organ or tissue.  Treatment recommendations for the management of irAEs 
are outlined in Section 5.5.5.6.
5.5.5.5. Management of Avelumab Infusion-Related Reactions
Since avelumab is administered IV, infusion-related reactions may occur.  Symptoms of 
infusion-related reactions include but are not limited to fever, chills, flushing, hypotension, 
dyspnea, wheezing, back pain, abdominal pain, and urticaria.  Management of 
infusion-related reactions should follow the guidelines set forth in Table 5.

Table 5.
Treatment Modification for Symptoms of Infusion Related Reactions 
Caused by Avelumab
NCI-CTCAE Grade 
Treatment Modification for Avelumab
Grade 1 – mild

Mild transient reaction; infusion 
interruption not indicated; intervention not 
indicated.

Decrease the avelumab infusion rate by 
50%* and monitor closely for any 
worsening.
Grade 2 – moderate

Therapy or infusion interruption indicated 
but responds promptly to symptomatic 
treatment (for example, antihistamines, 
NSAIDs, narcotics, IV fluids); prophylactic 
medications indicated for 24 hours.

Temporarily discontinue avelumab infusion.

Resume infusion at 50% of previous rate* 
once infusion-related reaction has resolved 
or decreased to at least Grade 1 in severity, 
and monitor closely for any worsening.

If a Grade 2 infusion related reaction does 
not improve or worsens following the 
decrease in infusion rate and appropriate 
symptomatic treatment the infusion should 
not be resumed for that day. 
Grade 3 or Grade 4 – severe or life-threatening

Grade 3: Prolonged (for example, not 
rapidly responsive to symptomatic 
medication and/or brief interruption of 
infusion); recurrence of symptoms 
following initial improvement; 
hospitalization indicated for clinical 
sequelae.

Grade 4: Life-threatening consequences; 
urgent intervention indicated.

Stop the avelumab infusion immediately 
and disconnect infusion tubing from the 
subject.

Subjects have to be withdrawn immediately 
from avelumab treatment and must not 
receive any further avelumab treatment.
IV: intravenous; NCI-CTCAE: National Cancer Institute-Common Terminology Criteria for Adverse Event; 
NSAIDs: nonsteroidal anti-inflammatory drugs.
*If avelumab infusion rate has been decreased by 50% due to an infusion reaction, it must remain decreased 
for the next scheduled infusion.  If no infusion reaction is observed at the next scheduled infusion, the 
infusion rate may be returned to baseline at subsequent infusions.
Additional Modifications for Patients with Grade 2 Infusion-Related Reactions: 
In the event of a Grade 2 infusion-related reaction that does not improve or worsens after 
implementation of the modifications indicated in Table 5 (including reducing the infusion 
rate by 50%), the investigator may consider treatment with corticosteroids, and the infusion 
should not be resumed for that avelumab dose.  At the next avelumab dose, the investigator 
may consider the addition of H2-blocker antihistamines (eg, famotidine or ranitidine), 
meperidine, or ibuprofen to the mandatory premedication as clinically indicated.  
Prophylactic steroids are NOT permitted.

5.5.5.6. Management of Avelumab Immune-Related Adverse Events
Since inhibition of PD-L1 stimulates the immune system, irAEs may occur.  Treatment of 
irAEs is mainly dependent upon severity as reported in Table 6:

Grade 1 to 2: treat symptomatically or with moderate dose steroids, more frequent 
monitoring;

Grade 1 to 2 (persistent): manage similar to high grade AE (Grade 3 to 4);

Grade 3 to 4: treat with high dose corticosteroids.
For any irAE of any grade, the investigator may consider consulting with the sponsor’s 
medical monitor if deemed necessary.
Treatment of irAEs should follow guidelines set forth in Table 6.
Some potential immune-related adverse events described with anti-PD-L1 monoclonal 
antibodies such as avelumab may overlap with some axitinib toxicities (eg, diarrhea, liver 
function tests increase).  Any adverse event suspected to be immune-related should be 
managed according to the guidance for management of immune-related adverse events in this 
Section 5.5.5.6.
For overlapping potential immune-related toxicities, follow the specific management
recommendations described in Table 6.

5.6. Investigational Product Storage 
The investigator or an approved representative, eg, pharmacist, will ensure that all 
investigational products are stored in a secured area with controlled access under required 
storage conditions and in accordance with applicable regulatory requirements.
Investigational products should be stored in their original containers and in accordance with 
the labels. 
See the IP manual for storage conditions of the product once reconstituted and/or diluted (for 
avelumab only).
Any storage conditions stated in the SRSD will be superseded by the storage conditions 
stated on the product label.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018

Page 64
Site systems must be capable of measuring and documenting (for example, via a log), at a 
minimum, daily minimum and maximum temperatures for all site storage locations (as 
applicable, including frozen, refrigerated, and/or room-temperature products).  This should 
be captured from the time of investigational product receipt throughout the study.  Even for 
continuous-monitoring systems, a log or site procedure that ensures active evaluation for 
excursions should be available.  The intent is to ensure that the minimum and maximum 
temperature is checked each business day to confirm that no excursion occurred since the last 
evaluation and to provide the site with the capability to store or view the minimum/maximum 
temperature for all non-working days upon return to normal operations.  The operation of the 
temperature monitoring device and storage unit (for example, refrigerator), as applicable, 
should be regularly inspected to ensure they are maintained in working order. 
Any excursions from the product label storage conditions should be reported to Pfizer upon 
discovery.  The site should actively pursue options for returning the product to the storage 
conditions described in the labeling, as soon as possible.  Deviations from the storage 
requirements, including any actions taken, must be documented and reported to Pfizer. 
Once an excursion is identified, the investigational product must be quarantined and not used 
until Pfizer provides permission to use the investigational product.  It will not be considered a 
protocol deviation if Pfizer approves the use of the investigational product after the 
temperature excursion.  Use of the investigational product prior to Pfizer approval will be 
considered a protocol deviation. 
Specific details regarding information the site should report for each excursion will be 
provided to the site.
Receipt of materials, door opening and closing, and other routine handling operations where 
the products are briefly out of the temperature range described in the labeling are not 
considered excursions.
Site staff will instruct patients on the proper storage requirements for take home 
investigational products. 
5.7. Investigational Product Accountability 
The investigator site must maintain adequate records documenting the receipt, use, loss, or 
other disposition of the investigational product supplies.  All investigational products will be 
accounted for using a drug accountability form/record.  All bottles of study drug must be 
returned to the investigator by the patient at every visit and at the end of the trial.
5.8. Destruction of Investigational Product Supplies 
The sponsor or designee will provide guidance on the destruction of unused investigational 
product (eg, at the site).  If destruction is authorized to take place at the investigator site, the 
investigator must ensure that the materials are destroyed in compliance with applicable 
environmental regulations, institutional policy, and any special instructions provided by 
Pfizer, and all destruction must be adequately documented.

5.9. Concomitant Treatment(s)
Medications or vaccinations specifically prohibited in the exclusion criteria are also not 
allowed during the active treatment period.
If there is a clinical indication for one of these or other medications or vaccinations 
specifically prohibited during the trial, discontinuation from study therapy or 
medication/vaccination may be required.  The final decision on any supportive therapy or 
vaccination rests with the Investigator and/or the patient’s primary physician.  However, the 
decision to continue the patient on study therapy or medication/vaccination schedule requires 
the mutual agreement of the Investigator, the Sponsor, and the patient.
Concomitant treatment considered necessary for the patient’s well-being may be given at 
discretion of the treating physician.
Concomitant medications and treatments, including herbal supplements, will be recorded 
from 28 days prior to the start of study treatment(s) and up to 90 days after the last dose of 
study treatment(s).  All concomitant medications should be recorded in the CRF including 
supportive care drugs (eg, antiemetic treatment and prophylaxis), and the drugs used to treat 
adverse events or chronic diseases, as well as non-drug supportive interventions 
(eg, transfusions).
Concurrent anti-cancer therapy with agents other than study treatments is not allowed.  
Medications intended solely for supportive care (ie, antiemetics, analgesics, megestrol 
acetate for anorexia) are allowed.
Recommended medications to treat infusion-related reactions, hypersensitivity reactions, and 
immune-related events are reported in Section 5.5.5.5 and Section 5.5.5.6, respectively.
5.9.1. Inhibitors and Inducers of Cytochrome P450 (CYP) Enzymes
In vitro studies with human liver microsomes and recombinant CYP enzymes indicate that
axitinib metabolism is primarily mediated by the CYP3A4/5, and to a lesser extent by
CYP1A2, CYP2C19, and UGT1A1.
The concomitant use of strong CYP3A4/5 inhibitors (eg, ketoconazole, itraconazole, 
clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, 
telithromycin, diltiazem and voriconazole) should be avoided.  Selection of an alternate 
concomitant medication with no or minimal CYP3A4/5 inhibition potential is recommended.  
Although axitinib dose adjustments have not been studied in patients receiving strong 
CYP3A4/5 inhibitors, a dose reduction of approximately half is recommended, as this dose 
reduction is predicted to adjust the axitinib area under the plasma concentration vs time curve 
(AUC) to the range observed without inhibitors.  The subsequent doses can be increased or 
decreased based on individual safety and tolerability.  If co-administration of the strong 
inhibitor is discontinued, the INLYTA dose should be returned (after 3 to 5 half-lives of the 
inhibitor) to that used prior to initiation of the strong CYP3A4/5 inhibitor.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 66
If coadministration of the strong CYP3A4/5 inhibitor is discontinued, the axitinib dose 
should be re-escalated (after 10 days) to that used prior to initiation of the strong CYP3A4/5 
inhibitor.
Coadministration of axitinib with strong CYP3A4/5 inducers (eg, rifampin, dexamethasone, 
phenytoin, carbamazepine, rifabutin, rifapentin, phenobarbital, and St. John’s wort) should be 
avoided.  Selection of concomitant medication with no or minimal CYP3A4/5 induction 
potential is recommended.  Moderate CYP3A4/5 inducers (eg, bosentan, efavirenz, 
etravirine, modafinil, and nafcillin) may also reduce the plasma exposure of axitinib and 
should be avoided if possible.  Consider a dose increase if axitinib must be dosed with a 
CYP3A4/5 inducer.
If coadministration of the strong CYP3A4/5 inducer is discontinued, the axitinib dose should 
be de-escalated (after 10 days) to that used prior to initiation of the strong CYP3A4/5 
inducer.
A listing of CYP3A4 inhibitors and inducers will be provided to the sites and updated as 
needed.
5.9.2. Hematopoietic Growth Factors
Granulocyte colony stimulating factor may be used in agreement with American Society of
Clinical Oncology (ASCO) guidelines80 or as allowed per local guidance.
Patients who enter the study on stable doses of erythropoietin or darbepoietin may continue 
this treatment, and patients may start either drug during the study at the discretion of the 
treating physician. 
5.9.3. Concomitant Surgery
Caution is advised on theoretical grounds for any surgical procedures during the study. 
No formal studies of the effect of axitinib on wound healing have been conducted; however, 
caution is advised based on the mechanism of action. If a major surgery or an interventional
procedure (eg, endoscopy) is required, treatment with axitinib must be interrupted at least 
24 hours before the procedure, and the patient BP should be monitored closely for 
hypotension.  Patients may resume axitinib 7 days after minor surgery and 2-3 weeks after
major surgery, assuming the wound has completely healed and there are no wound healing
complications (eg, delayed healing, wound infection or fistula).
There is no evidence suggesting that treatment with avelumab increases surgical risk.  
Postoperatively, the decision to reinitiate investigational products should be discussed with 
the Sponsor. 
In the case that a surgical procedure is required for palliative care, all attempts should be 
made to rule out disease progression beforehand.

Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 67
5.9.4. Concomitant Radiotherapy
Palliative radiotherapy to specific sites of disease is permitted if considered medically 
necessary by the treating physician.  All attempts should be made to rule out disease 
progression in the event of increased localized pain.  If palliative radiotherapy is needed to 
control bone pain, the sites of bone disease should be present at baseline; otherwise, bone 
pain requiring radiotherapy will be considered as a sign of disease progression.  Study 
treatment should be withheld for the entire duration of palliative radiotherapy and can be 
restarted upon recovery from any radiotherapy-related toxicities, but no sooner than 48 hours 
after radiotherapy completion. 
5.9.5. Other Prohibited Concomitant Medications and Therapies
Patients are prohibited from receiving the following therapies during the treatment phase of 
this trial: 

Anti-cancer systemic chemotherapy or biological therapy.

Immunotherapy not specified in this protocol. 

Investigational agents other than investigational products. 

Radiation therapy (with the exception noted above in the Concomitant Radiotherapy 
Section 5.9.4).

Immunosuppressive drugs, unless otherwise indicated for the treatment of irAEs 
(see).  See below Clarification Regarding Steroid Use.

Other experimental pharmaceutical products.

Any vaccine therapies for the prevention of infectious disease (eg, human papilloma 
virus vaccine) except for inactivated vaccines (eg, influenza vaccine).

Herbal remedies with immunostimulating properties (eg, mistle toe extract) or those 
known to potentially interfere with major organ function (eg, hypericin).

Bisphosphonate or denosumab treatment unless it has been initiated more than 
14 days prior to enrollment. 
There are no prohibited therapies during the Post-Treatment Follow-up Phase. 
Restrictions for Steroid Use: Data indicate that corticosteroids have an adverse effect on 
T-cell function and that they inhibit and damage lymphocytes.81,82  Furthermore, as for all 
immunotherapies intended to augment T-cell-mediated immunity, there is a risk that 
concomitant immunosuppressives such as steroids will counteract the intended benefit.  
However, studies with anti-CTLA-4 compounds indicate that short term use of steroids can 
be employed without compromising clinical outcomes.82  Therefore, the use of steroids 
during this trial is restricted as follows:

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 68

Therapeutic use: for the treatment of infusion-related reactions and for the treatment 
of irAEs, steroids are permitted according to the modalities indicated in Table 6.

Physiologic use: replacement for adrenal insufficiency at doses equivalent to 10 mg 
prednisone daily are acceptable.

Intranasal, inhaled, topical steroids, or local steroid injections (eg, intra-articular 
injection) are permitted. 
5.10. Rescue Medications and Supportive Care
5.10.1. Supportive Care Guidelines
Patients should receive appropriate supportive care measures as deemed necessary by the 
treating Investigator including but not limited to the items outlined below: 

Diarrhea: All patients who experience diarrhea should be advised to drink liberal 
quantities of clear fluids.  If sufficient oral fluid intake is not feasible, fluid and 
electrolytes should be substituted via IV infusion.88

Nausea/Vomiting: Nausea and vomiting should be treated aggressively, and 
consideration should be given in subsequent cycles to the administration of 
prophylactic antiemetic therapy according to standard institutional practice.89  
Patients should be strongly encouraged to maintain liberal oral fluid intake. 

Anti-infectives: Patients with a documented infectious complication should receive 
oral or IV antibiotics or other anti-infective agents as considered appropriate by the 
treating Investigator for a given infectious condition, according to standard 
institutional practice.  Prophylactic administration should be considered for the cases 
outlined in Table 6.

Anti-inflammatory or narcotic analgesics may be offered as needed. 

Patients who need to be on anticoagulant therapy during treatment should be treated 
with low molecular weight heparin.  If low molecular weight heparin cannot be 
administered, coumadin or other coumarin derivatives or other anti-coagulants 
(including direct Xa inhibitors) may be allowed; however, appropriate monitoring of 
prothrombin time/international normalized ratio (PT/INR) should be performed.
6. STUDY PROCEDURES 
6.1. Screening
For screening procedures, see Schedule of Activities (SOA) and Assessments section
(Section 7).

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 69
6.1.1. Tumor Biospecimens
Archived tumor tissue from the most recent primary or metastatic tumor biopsy or resection 
is required to be available.  If there is no archived tumor available, then a de novo (ie, fresh) 
tumor sample should be obtained prior to study enrollment.
For any sample of tumor tissue, one FFPE tissue block should be provided if available and 
permitted by local laws and policies.  If one or more blocks cannot be provided for these 
reasons, then sections must be freshly cut (ie, cut no more than 30 days prior to shipment to 
the central laboratory), 4-5 m thick and mounted on positively-charged microscope slides 
(SuperFrost Plus glass slides are recommended).  Fifteen slides (minimum 10) should be 
provided. 
A minimum 18 gauge core needle should be used in biopsies in order to maximize the quality 
and value of obtained tissue; a minimum of 3 separate cores is requested for each biopsy 
procedure.  Tumor tissue from cytologic sampling (eg, fine needle aspiration, including 
FFPE cell pellet material) is not adequate and should not be submitted. 
Additional information on tumor biospecimen collection procedures is included in the Study 
Manual.
6.2. Study Treatment Period
For treatment period procedures, see the Schedule of Activities.
6.3. Patient Withdrawal/End of Treatment
For End of Treatment visit procedures, please see Schedule of Activities and Section 7.
Patients may withdraw from study treatment or the study overall at any time at their own 
request, or they may be withdrawn at the discretion of the Investigator or Sponsor for safety 
or behavioral reasons, or the inability of the patient to comply with the protocol-required 
schedule of study visits or procedures at a given study site. 
Reasons for withdrawal of study treatment may include:

Objective disease progression.  However, patients with disease progression who are 
continuing to derive clinical benefit from the study treatment will be eligible to 
continue study treatment, provided that the treating physician has determined that the 
benefit/risk for doing so is favorable (See Section 5.5.3 for details and exceptions); 

Global deterioration of health status requiring discontinuation;

Unacceptable toxicity.  If the unacceptable toxicity is attributed to 1 of the 
investigational products, the Investigator may continue treatment with the other 
investigational product(s); 

Pregnancy;

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 70

Significant protocol violation;

Lost to follow-up;

Patient refused further treatment;

Study terminated by Sponsor;

Death.
Reasons for withdrawal from the study may include:

Study terminated by Sponsor;

Lost to follow-up;

Refused further follow-up;

Death.
If a patient does not return for a scheduled visit, every effort should be made to contact the 
patient.  All attempts to contact the patient and information received during contact attempts 
must be documented in the patient’s medical record.  In any circumstance, every effort 
should be made to document patient outcome, if possible.  The Investigator should inquire 
about the reason for withdrawal, request that the patient return for a final visit, if applicable, 
and follow-up with the patient regarding any unresolved AEs.
If the patient refuses further visits, the patient should continue to be followed for survival 
unless the patient withdraws consent for disclosure of future information or for further 
contact.  In this case, no further study specific evaluations should be performed, and no 
additional data should be collected.  The Sponsor may retain and continue to use any data 
collected before such withdrawal of consent.
6.3.1. Withdrawal of Consent
Patients who request to discontinue receipt of study treatment will remain in the study and 
must continue to be followed for protocol specified follow-up procedures.  The only 
exception to this is when a patient specifically withdraws consent for any further contact with 
him or her or persons previously authorized by the patient to provide this information.  
Patients should notify the investigator in writing of the decision to withdraw consent from 
future follow-up, whenever possible.  The withdrawal of consent should be explained in 
detail in the medical records by the investigator, as to whether the withdrawal is only from 
further receipt of investigational product (in which case the withdrawal of consent form is not 
applicable) or also from study procedures and/or posttreatment study follow-up (in which 
case a withdrawal of consent form should be provided and signed).  In the event that vital 
status (whether the patient is alive or dead) is being measured, publicly available information 

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 71
should be used to determine vital status only as appropriately directed in accordance with 
local law.
6.3.2. Lost to Follow-up 
All reasonable efforts must be made to locate patients to determine and report their ongoing 
status.  This includes follow-up with persons authorized by the patient as noted above.  Lost 
to follow-up is defined by the inability to reach the patient after a minimum of 2 documented 
phone calls, faxes, or e-mails as well as lack of response by the patient to 1 registered mail 
letter.  All attempts should be documented in the patient’s medical records.  If it is 
determined that the patient has died, the site will use locally permissible methods to obtain 
the date and cause of death.  If the investigator’s use of a third-party representative to assist 
in the follow-up portion of the study has been included in the patient’s informed consent, 
then the investigator may use a sponsor-retained third-party representative to assist site staff 
with obtaining the patient’s contact information or other public vital status data necessary to 
complete the follow-up portion of the study.  The site staff and representative will consult 
publicly available sources, such as public health registries and databases, in order to obtain 
updated contact information.  If, after all attempts, the patient remains lost to follow-up, then 
the last-known-alive date as determined by the investigator should be reported and 
documented in the patient’s medical records.
6.4. Short-Term Follow-up
For follow-up procedures see the Schedule of Activities and ASSESSMENTS section. 
In Short-term Follow-up, patients should be evaluated up to 90 days (30 days, 60 days, and 
90 days 3 days) after last dose of investigational product(s) for safety or until the time of
initiation of new anti-cancer treatment.  Patients continuing to experience study drug-related 
toxicity following discontinuation of investigational products will continue to be followed at 
least every 4 weeks regardless of initiation of new anti-cancer treatment until resolution or 
determination, in the clinical judgment of the Investigator, that no further improvement is 
expected.  Physical examination, ECOG status, vital signs, and safety laboratory 
measurements are not required for patients who initiate new anti-cancer treatment, unless the 
patient continues to experience toxicity following discontinuation of the investigational 
products.  Contraception check and serum/urine pregnancy tests are required up to 30 days 
after last dose of avelumab (90 days for male patients) and 90 days after last dose of axitinib 
for all patients who enter Short-term Follow-up regardless of initiation of subsequent 
anti-cancer therapy. 
6.5. Long-Term Follow-up
Following completion of the Short-term Follow-up period, all patients will be followed for 
survival and subsequent anti-cancer treatments every 12 weeks (14 days) until death, end of 
the study, or patient withdrawal of consent, whichever comes first; new systemic anti-cancer 
treatment will also be recorded.  These visits may be conducted in-clinic or by remote contact 
(eg, telephone). 

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 72
Patients whose disease has not progressed at the time of End of Treatment will continue to 
undergo disease assessments every 8 weeks for 1 year from the start of study treatment and 
then every 12 weeks thereafter until documented disease progression regardless of 
discontinuation of study treatment or initiation of subsequent anti-cancer therapy
(see Section 7.6). 
7. ASSESSMENTS
Every effort should be made to ensure that the protocol-required tests and procedures are 
completed as described.  However, it is anticipated that from time to time there may be 
circumstances, outside of the control of the Investigator that may make it unfeasible to 
perform the test.  In these cases the Investigator will take all steps necessary to ensure the 
safety and well-being of the patient.  When a protocol-required test cannot be performed, the 
Investigator will document the reason for this and any corrective and preventive actions that 
he or she has taken to ensure that normal processes are adhered to as soon as possible.  The 
study team will be informed of these incidents in a timely fashion.
For samples being collected and shipped, detailed collection, processing, storage, and 
shipment instructions and contact information will be provided to the investigator site prior 
to initiation of the study.
7.1. Safety Assessment
Safety assessments will include collection of AEs, Serious Adverse Events (SAEs), vital 
signs and physical examination, electrocardiogram (ECG) (12-lead), LVEF by MUGA scan
or Echocardiogram, laboratory assessments, including pregnancy tests, and verification of 
concomitant treatments.  See also Schedule of Activities. 
7.1.1. Pregnancy Testing
For female patients of childbearing potential, a serum or urine pregnancy test, with 
sensitivity of at least 25 mIU/mL, and assayed in a certified laboratory, will be performed on 
2 occasions prior to starting study treatments; once at the start of screening and once at the 
baseline visit, immediately before study drugs administration.  Following a negative 
pregnancy test result at screening, appropriate contraception must be commenced and another 
negative pregnancy test result will then be required at the baseline visit before the patient 
may receive the investigational products.  Additional pregnancy tests (serum or urine) will be 
repeated at every treatment cycle, on the day of dosing (results should be available prior to 
dosing), during the active treatment period, at the end of treatment, during follow-up for at 
least 90 days after the last dose of axitinib or for at least 30 days after last dose of avelumab 
and additionally whenever 1 menstrual cycle is missed or when potential pregnancy is 
otherwise suspected.  Additional pregnancy tests may also be undertaken if requested by 
IRBs/ECs or if required by local regulations.  In the case of a positive confirmed pregnancy, 
the patient will be withdrawn from administration of investigational product but should 
remain in the study.  See also Schedule of Activities.

7.1.2. Contraceptive Check
Fertile male patients and female patients who are of childbearing potential, who are, in the 
opinion of the Investigator, sexually active and at risk for pregnancy with their partner(s), 
will need to affirm that they meet the criteria for correct use of 2 of the selected methods of 
contraception (at least one of which is considered to be highly effective with low user 
dependency as defined in Section 4.3.1).  The Investigator or his or her designee will discuss 
with the patient the need to use 2 contraception methods consistently and correctly and 
document such conversation in the patient’s chart.  In addition, the Investigator or his or her 
designee will instruct the patient to call immediately if one or both selected contraception 
methods are discontinued, or if pregnancy is known or suspected in the patient or the 
patient’s partner.  Patients who are, in the opinion of the Investigator, sexually active and at 
risk for pregnancy with their partner(s) must agree to use 2 methods of contraception (at least 
one of which is considered to be highly effective with low user dependency as defined in 
Section 4.3.1) throughout the study for at least 90 days after last dose of axitinib or at least 
30 days after the last dose of avelumab (90 days for male patients).  See Section 4.3.1 for 
more details.
7.1.3. Adverse Events
Assessment of adverse events will include the type, incidence, severity (graded by NCI 
CTCAE version 4.03), timing, seriousness, and relatedness.
7.1.4. Laboratory Safety Assessments
Hematology and blood chemistry will be drawn at the time points described in the Schedule 
of Activities and analyzed at local laboratories.  Laboratory safety assessments may also be 
performed when clinically indicated.  The required laboratory tests are listed in Table 7. 
Laboratory safety assessments must be performed and results reviewed by the treating 
physician prior to study treatment administration.

7.1.5. Physical Examinations and Vital Signs
Patients will have a physical examination to include major body systems, supine or sitting 
blood pressure, pulse rate, body temperature, assessment of ECOG performance status, 
weight, and height (height will be measured at screening only) at the time points described in 
the Schedule of Activities. Blood pressure and pulse rate should be taken after the patient has 
been lying down or sitting quietly for at least 5 minutes. 
7.1.6. (12-Lead) Electrocardiogram Measurements
A standard 12-lead (with a 10-second rhythm strip) tracing will be used for all ECGs.  It is 
preferable that the machine used has a capacity to calculate the standard intervals 
automatically. 
A single ECG is to be performed at Screening, as clinically indicated and EOT.  Clinically 
significant abnormal findings in baseline ECGs will be recorded as medical history. If the 
QTc is prolonged (>500 msec, ie, CTCAE Grade 3), then a triplicate ECG (3 consecutive 
12-lead ECGs approximately 2 minutes apart) will be collected to confirm the original 
measurement.  If the mean QTc of the triplicate ECG is >500 msec then the ECGs will be 
re-evaluated by a qualified person at the site for confirmation as soon as the finding is made, 
including verification that the machine reading is accurate.  If manual reading verifies a QTc 
of >500 msec, immediate correction for reversible causes (including electrolyte 
abnormalities, hypoxia and concomitant medications for drugs with the potential to prolong 
the QTc interval) should be performed.  In addition, single ECGs should be repeated hourly 
for at least 3 hours until the QTc interval falls below 500 msec.  If QTc interval reverts to 
less than 500 msec, and in the judgment of the investigator(s) and sponsor is determined to 
be due to cause(s) other than investigational product, treatment may be continued with 
regular ECG monitoring as clinically indicated.  If in that timeframe the QTc intervals rise 
above 500 msec the investigational product will be held until the QTc interval decreases to 
500 msec.  If the QTc interval has still not decreased to <500 msec after 2-weeks, or if at
any time a patient has a QTc interval >515 msec or becomes symptomatic, the patient will be 
removed from the study.
Each episode of prolongation of the QTc interval will be evaluated by a specialist to 
determine if due to the investigational product or due to other potential precipitating factors 
(eg, change in patient clinical condition, effect of concurrent medication, electrolyte 
disturbance).
If a patient experiences any cardiac or neurologic AEs (especially syncope, dizziness, 
seizures, or stroke), an ECG in triplicate should be obtained at the time of the event. 
7.1.7. Left Ventricular Ejection Fraction by MUGA Scan or Echocardiogram
For the evaluation of LVEF, both MUGA and Echocardiogram are acceptable.  The same 
technique used at screening must be consistently used for the following assessments 
throughout the study. Please see Schedule of Activities.

7.2. Pharmacokinetics Assessments
7.2.1. Blood Sample Collection for Pharmacokinetic Analysis
Blood samples will be collected for PK analysis of avelumab and axitinib into the appropriate 
tubes as outlined in the Schedule of Activities, Section 7.2.2 and Section 7.2.3.  PK sampling 
schedule may be modified based on emerging PK data.  Blood for PK samples will be drawn 
from the arm contralateral to the drug infusion. 
All efforts will be made to obtain the PK samples at the scheduled nominal time relative to 
dosing.  However, with the exception of samples where nominal time coincides with end of 
infusion, samples obtained within ±10% of the nominal time (eg, within 3 minutes of a 
30 minute sample) will not be captured as a protocol deviation, as long as the exact time of 
the sample collection is noted on the source document and data collection tool (eg, CRF).  
For samples where nominal time coincides with end of infusion, a sample collected within 
10 min post end of infusion will not be captured as a protocol deviation.  If the infusion of 
avelumab is interrupted due to AE, any PK samples scheduled during the time of the dosing 
interruption are not required.  If a scheduled blood sample collection cannot be completed for 
any reason, the missed sample time may be re-scheduled with agreement of clinical 
investigators, patient and Sponsor.
•
Details regarding the collection, processing, storage and shipping of the blood 
samples will be provided to the investigator site prior to initiation of the trial.
•
Samples will be analyzed using a validated analytical method in compliance with 
Pfizer standard operating procedures.
•
The samples must be processed and shipped as indicated to maintain sample integrity.  
Any deviations from the processing steps (eg, sample collection and processing steps, 
interim storage or shipping conditions), including any actions taken, must be 
documented and reported to the sponsor.  On a case by case basis, the sponsor may 
make a determination as to whether sample integrity has been compromised.  Any 
deviation from the specified sample handling procedure resulted in compromised 
sample integrity, will be considered a protocol deviation.
 
 
 
 
7.2.2. Collection of Axitinib Pharmacokinetic Samples
At each time point for axitinib, a 3 mL whole blood sample will be collected into an
appropriately labeled K3EDTA (tripotassium edetic acid [ethylenediaminetetraacetic acid])
tube to provide a minimum of 1 mL plasma for axitinib PK analysis.

7.2.3. Collection of Avelumab Pharmacokinetic Samples
A 3.5 mL whole blood sample will be collected into a Serum Separator Tube (SST) at the 
designated times to provide serum for avelumab PK analysis.  Pre-dose samples can be taken
up to 2 hours prior to the start of avelumab infusion.
7.3. Immunogenicity Assessment
Blood samples (3.5 mL whole blood) will be collected for assessment of avelumab ADAs 
into an appropriately labeled SST.  Predose ADA samples will be collected within 2 hours 
prior to dosing.  Further details can be found in the Lab Manual.  This assessment will take 
place at regular intervals during the treatment and follow-up periods as described in the 
Schedule of Activities. 
A tiered ADA testing strategy will be used: all samples that are positive in the screening 
assay will be confirmed for antibody specificity.  Confirmed positive samples will be further 
characterized for titer and tested in the NAb assay, if appropriate.

Details regarding the collection, processing, storage and shipping of the blood 
samples will be provided to the investigator site prior to initiation of the trial.

make a determination as to whether sample integrity has been compromised.  Any 
deviation from the specified sample handling procedure resulted in compromised 
sample integrity, will be considered a protocol deviation.
7.4. Translational and Pharmacodynamic Assessments
Whole blood samples 
 
one 10 mL, red-top serum Becton Dickinson (BD) Vacutainer® tube for serum

Unless prohibited by local regulations or ethics committee decision, a saliva sample will be 
collected on Cycle 1, Day 1 before the first dose of study drug treatment to be used as a 
germline control to assist in identifying and profiling tumor mutations. 
7.4.1. Archived Tumor Biospecimens and De Novo Tumor Biopsies
Archived tumor tissue samples and de novo biopsies of primary and/or metastatic lesions (see
Section 6.1.1) will be used to analyze candidate DNA, RNA, or protein markers, or relevant
signature of markers for their ability to identify those patients who are most likely to benefit
from treatment with the study drugs.
Markers that may be analyzed include, but may not necessarily be limited to, the 
presence/absence of tumor-infiltrating CD8+ T lymphocytes and/or expression of PD-L1, 
within the tumor microenvironment and tumor mutational burden.

7.6. Tumor Assessments 
The decision for body areas to be scanned will depend on the disease under study and the 
extent of disease.  Tumor assessments must include all known or suspected disease sites.  
The minimum recommended body areas to be scanned depending upon malignancy are 
detailed in the Imaging Manual. 
Baseline scans must be performed within 28 days prior to first dose of study drug. 
Anti-tumor activity will be assessed through radiological tumor assessments conducted at 
baseline, then every 8 weeks from first dose of study drug for 1 year from start of study 
treatment, and then every 12 weeks thereafter until PD regardless of discontinuation of study 
treatment or initiation of subsequent anti-cancer therapy, as specified in the Schedule of 
Activities. In addition, radiological tumor assessments will be conducted whenever PD is 
suspected (eg, symptomatic deterioration).

The schedule of tumor assessments should be fixed according to the calendar regardless of 
treatment schedule or treatment delays or interruptions due to toxicity. 
Imaging may include chest, abdomen and pelvis computed tomography (CT) or magnetic 
resonance imaging (MRI) scans. 
Brain CT or MRI scans are required at baseline for all patients with stable brain lesions and 
for those for whom brain metastasis is suspected.  If stable brain metastases are present at 
baseline, brain imaging should be repeated at each tumor assessment.  Otherwise, brain 
imaging will be conducted post- baseline only when clinically indicated.
Bone imaging using bone scan (bone scintigraphy) (preferred method) or other methods 
considered standard of care locally such as 18-fluorodeoxyglucose positron emission 
tomography (18F-FDG-PET/CT) or CT or MRI is required at baseline.  Bone lesion(s) 
identified at baseline by bone scan will be further assessed by diagnostic CT or MRI as per 
local practice (where bone scans are not used as a routine restaging tool) and subsequently 
re-assessed by diagnostic CT or MRI as per the tumor assessment schedule as an alternative 
to bone scans.  Bone scans will only be repeated during study as clinically indicated 
(ie, patient describes new or worsening bone pain, or has increasing alkaline phosphatase 
level or other signs and symptoms of new/progressing bone metastases), at the time of
confirmation of CR, and at every other tumor assessment visit (ie, every 16 weeks during the 
first 12 months of study treatment and every 32 weeks thereafter) if considered local standard 
of care.
The CT and MRI scans should be performed with contrast agents unless contraindicated for 
medical reasons.  The same imaging technique used to characterize each identified and 
reported lesion at baseline will be employed in the following tumor assessments.
Assessment of response will be made using RECIST v1.1 (Appendix 4) 
 
 Measurable or evaluable lesions that have been previously irradiated will not 
be considered target lesions unless increase in size has been observed following completion 
of radiation therapy.
In case CR or PR is observed, tumor assessments must be confirmed on repeated imaging at 
least 4 weeks after initial documentation.  If radiologic imaging shows PD, then the tumor 
assessment should be repeated after at least 4 weeks to confirm PD.  See Section 5.5.3 for 
treatment after initial evidence of PD.  If the patient begins a new anti-cancer therapy prior to 
confirmation of PD, then the confirmatory assessment is not required. 
All patients’ files and radiologic images must be available for source verification and for 
potential peer review.  All radiographic images will be collected and stored by an 
independent third-party imaging laboratory, according to instructions in the Imaging Manual.

8. ADVERSE EVENT REPORTING
8.1. Requirements
The table below summarizes the requirements for recording safety events on the CRF and for 
reporting safety events on the Clinical Trial (CT) Serious Adverse Event (SAE) Report Form 
to Pfizer Safety.  These requirements are delineated for 3 types of events: (1) SAEs; 
(2) non-serious adverse events (AEs); and (3) exposure to the investigational product under 
study during pregnancy or breastfeeding, and occupational exposure. 
Safety Event
Recorded on the CRF
Reported on the CT SAE 
Report Form to Pfizer 
Safety Within 24 Hours of 
Awareness
SAE
All
All
Non-serious AE
All
None
Exposure to the 
investigational product 
under study during 
pregnancy or 
breastfeeding, and 
occupational exposure
All (regardless of whether 
associated with an AE), 
except occupational 
exposure
Exposure during pregnancy, 
exposure via breastfeeding, 
occupational exposure 
(regardless of whether 
associated with an AE)
All observed or volunteered events regardless of treatment group or suspected causal 
relationship to the investigational product(s) will be reported as described in the following 
paragraphs.
Events listed in the table above that require reporting to Pfizer Safety on the CT SAE Report 
Form within 24 hours of awareness of the event by the investigator are to be reported 
regardless of whether the event is determined by the investigator to be related to an 
investigational product under study.  In particular, if the SAE is fatal or life-threatening, 
notification to Pfizer Safety must be made immediately, irrespective of the extent of available 
event information.  This time frame also applies to additional new (follow-up) information on 
previously forwarded reports.  In the rare situation that the investigator does not become 
immediately aware of the occurrence of an event, the investigator must report the event 
within 24 hours after learning of it and document the time of his/her first awareness of the 
event.
For each event, the investigator must pursue and obtain adequate information both to 
determine the outcome and to assess whether it meets the criteria for classification as an SAE 
(see the Serious Adverse Events section below).  In addition, the investigator may be 
requested by Pfizer Safety to obtain specific follow-up information in an expedited fashion.  
This information is more detailed than that recorded on the CRF.  In general, this will include 
a description of the event in sufficient detail to allow for a complete medical assessment of 
the case and independent determination of possible causality.  Any information relevant to 
the event, such as concomitant medications and illnesses, must be provided.  In the case of a 

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 82
patient death, a summary of available autopsy findings must be submitted as soon as possible 
to Pfizer Safety.  Any pertinent additional information must be reported on the CT SAE 
Report Form; additional source documents (eg, medical records, CRF, laboratory data) are to 
be sent to Pfizer Safety ONLY upon request.
As part of ongoing safety reviews conducted by the sponsor, any non-serious AE that is 
determined by the sponsor to be serious will be reported by the sponsor as an SAE.  To assist 
in the determination of case seriousness, further information may be requested from the 
investigator to provide clarity and understanding of the event in the context of the clinical 
study.
8.1.1. Additional Details On Recording Adverse Events on the CRF
All events detailed in the table above will be recorded on the AE page(s) of the CRF.  It 
should be noted that the CT SAE Report Form for reporting of SAE information is not the 
same as the AE page of the CRF.  When the same data are collected, the forms must be 
completed in a consistent manner.  AEs should be recorded using concise medical 
terminology and the same AE term should be used on both the CRF and the CT SAE Report 
Form for reporting of SAE information.
8.1.2. Eliciting Adverse Event Information
The investigator is to record on the CRF all directly observed AEs and all AEs spontaneously 
reported by the study patient.  In addition, each study patient will be questioned about the 
occurrence of AEs in a non-leading manner.
8.1.3. Withdrawal From the Study Due to Adverse Events (see also the Patient 
Withdrawal Section)
Withdrawal due to AEs should be distinguished from withdrawal due to other causes, 
according to the definition of AE noted below, and recorded on the CRF. 
When a patient withdraws from the study because of an SAE, the SAE must be recorded on 
the CRF and reported, as appropriate, on the CT SAE Report Form, in accordance with the 
Requirements section above.
8.1.4. Time Period for Collecting AE/SAE Information
The time period for actively eliciting and collecting AEs and SAEs (“active collection 
period”) for each patient begins from the time the patient provides informed consent, which 
is obtained before the patient’s participation in the study (ie, before undergoing any 
study-related procedure and/or receiving investigational product), through and including a 
minimum of 90 calendar days after the last administration of the investigational product.
For patients who are screen failures, the active collection period ends when screen failure 
status is determined.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 83
8.1.4.1. Reporting SAEs to Pfizer Safety
All SAEs occurring in a patient during the active collection period are reported to Pfizer 
Safety on the CT SAE Report Form.
SAEs occurring in a patient after the active collection period has ended are reported to Pfizer 
Safety if the investigator becomes aware of them; at a minimum, all SAEs that the 
investigator believes have at least a reasonable possibility of being related to investigational 
product must be reported to Pfizer Safety.
Follow up by the investigator continues throughout and after the active collection period and 
until the event or its sequelae resolve or stabilize at a level acceptable to the investigator, and 
Pfizer concurs with that assessment.
If a patient begins a new anti-cancer therapy, SAEs occurring during the above-indicated 
active collection period must still be reported to Pfizer Safety irrespective of any intervening 
treatment.
8.1.4.2. Recording Non-Serious AEs and SAEs on the CRF
During the active collection period, both non-serious AEs and SAEs are recorded on the 
CRF.
Follow-up by the investigator may be required until the event or its sequelae resolve or 
stabilize at a level acceptable to the investigator, and Pfizer concurs with that assessment.
If a patient begins a new anti-cancer therapy, the recording period for non-serious AEs ends 
at the time the new treatment is started; however, SAEs must continue to be recorded on the 
CRF during the above-indicated active collection period.
Death must be reported if it occurs during the SAE reporting period after the last dose of
study drug, irrespective of any intervening treatment.
8.1.5. Causality Assessment
The investigator’s assessment of causality must be provided for all AEs (serious and 
non-serious); the investigator must record the causal relationship on the CRF, and report such 
an assessment in accordance with the SAE reporting requirements, if applicable.  An 
investigator’s causality assessment is the determination of whether there exists a reasonable 
possibility that the investigational product caused or contributed to an AE; generally the facts 
(evidence) or arguments to suggest a causal relationship should be provided.  If the 
investigator does not know whether or not the investigational product caused the event, then 
the event will be handled as “related to investigational product” for reporting purposes, as 
defined by the sponsor.  If the investigator's causality assessment is “unknown but not 
related” to investigational product, this should be clearly documented on study records. 

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 84
In addition, if the investigator determines that an SAE is associated with study procedures, 
the investigator must record this causal relationship in the source documents and CRF, and 
report such an assessment in the dedicated section of the CT SAE Report Form and in 
accordance with the SAE reporting requirements.
8.1.6. Sponsor’s Reporting Requirements to Regulatory Authorities
AE reporting, including suspected unexpected serious adverse reactions, will be carried out 
in accordance with applicable local regulations.
8.2. Definitions
8.2.1. Adverse Events
An AE is any untoward medical occurrence in a study patient administered a product or 
medical device; the event need not necessarily have a causal relationship with the treatment 
or usage.  Examples of AEs include, but are not limited to: 

Abnormal test findings;

Clinically significant signs and symptoms;

Changes in physical examination findings;

Hypersensitivity;

Drug abuse;

Drug dependency.
Additionally, AEs may include signs and symptoms resulting from:

Drug overdose;

Drug withdrawal;

Drug misuse; 

Drug interactions;

Extravasation;

Exposure during pregnancy (EDP);

Exposure via breastfeeding;

Medication error;

Occupational exposure.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 85
Worsening of signs and symptoms of the malignancy under study should be recorded as AEs 
in the appropriate section of the CRF.  Disease progression assessed by measurement of 
malignant lesions on radiographs or other methods should not be reported as AEs.
8.2.2. Abnormal Test Findings
Abnormal objective test findings should be recorded as AEs when any of the following 
conditions are met: 

Test result is associated with accompanying symptoms; and/or

Test result requires additional diagnostic testing or medical/surgical intervention; 
and/or

Test result leads to a change in study dosing (outside of any protocol-specified dose 
adjustments) or discontinuation from the study, significant additional concomitant 
drug treatment, or other therapy; and/or

Test result is considered to be an AE by the investigator or sponsor.
Merely repeating an abnormal test, in the absence of any of the above conditions, does not 
constitute an AE.  Any abnormal test result that is determined to be an error does not require 
recording as an AE.
8.2.3. Serious Adverse Events
A serious adverse event is any untoward medical occurrence at any dose that:

Results in death;

Is life-threatening (immediate risk of death);

Requires inpatient hospitalization or prolongation of existing hospitalization;

Results in persistent or significant disability/incapacity (substantial disruption of the 
ability to conduct normal life functions);

Results in congenital anomaly/birth defect.
Or that is considered to be:

An important medical event.
Medical and scientific judgment is exercised in determining whether an event is an important 
medical event.  An important medical event may not be immediately life-threatening and/or 
result in death or hospitalization.  However, if it is determined that the event may jeopardize 
the patient or may require intervention to prevent one of the other AE outcomes, the 
important medical event should be reported as serious.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 86
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm; blood dyscrasias or convulsions that do not result in hospitalization; 
or development of drug dependency or drug abuse.
Progression of the malignancy under study (including signs and symptoms of progression) 
should not be reported as an SAE unless the outcome is fatal within the active collection 
period.  Hospitalization due to signs and symptoms of disease progression should not be 
reported as an SAE.  If the malignancy has a fatal outcome during the study or within the 
active collection period, then the event leading to death must be recorded as an AE on the 
CRF, and as an SAE with Common Terminology Criteria for Adverse Events (CTCAE) 
Grade 5 (see the Severity Assessment section).
8.2.4. Hospitalization
Hospitalization is defined as any initial admission (even less than 24 hours) in a hospital or 
equivalent healthcare facility, or any prolongation of an existing admission.  Admission also 
includes transfer within the hospital to an acute/intensive care unit (eg, from the psychiatric 
wing to a medical floor, medical floor to a coronary care unit, or neurological floor to a 
tuberculosis unit).  An emergency room visit does not necessarily constitute a hospitalization; 
however, the event leading to the emergency room visit is assessed for medical importance.
Hospitalization does not include the following:

Rehabilitation facilities;

Hospice facilities;

Respite care (eg, caregiver relief);

Skilled nursing facilities;

Nursing homes;

Same-day surgeries (as outpatient/same-day/ambulatory procedures).
Hospitalization or prolongation of hospitalization in the absence of a precipitating clinical 
AE is not in itself an SAE. Examples include:

Admission for treatment of a preexisting condition not associated with the 
development of a new AE or with a worsening of the preexisting condition (eg, for 
workup of a persistent pretreatment laboratory abnormality);

Social admission (eg, patient has no place to sleep);

Administrative admission (eg, for yearly physical examination);

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 87

Protocol-specified admission during a study (eg, for a procedure required by the study 
protocol);

Optional admission not associated with a precipitating clinical AE (eg, for elective 
cosmetic surgery);

Hospitalization for observation without a medical AE;

Preplanned treatments or surgical procedures.  These should be noted in the baseline 
documentation for the entire protocol and/or for the individual patient;

Admission exclusively for the administration of blood products.
Diagnostic and therapeutic noninvasive and invasive procedures, such as surgery, should not 
be reported as SAEs.  However, the medical condition for which the procedure was 
performed should be reported if it meets the definition of an SAE.  For example, an acute 
appendicitis that begins during the reporting period should be reported if the SAE 
requirements are met, and the resulting appendectomy should be recorded as treatment of the 
AE.
8.3. Severity Assessment
GRADE
Clinical Description of Severity
0 
No change from normal or reference range (This grade is not included in the 
Version 4.03 CTCAE document but may be used in certain circumstances.)
1
MILD adverse event
2
MODERATE adverse event
3
SEVERE adverse event
4
LIFE-THREATENING consequences; urgent intervention indicated
5
DEATH RELATED TO adverse event
Note the distinction between the severity and the seriousness of an AE.  A severe event is not 
necessarily an SAE.  For example, a headache may be severe (interferes significantly with 
the patient's usual function) but would not be classified as serious unless it met one of the 
criteria for SAEs, listed above.
8.4. Special Situations
8.4.1. Protocol-Specified Serious Adverse Events
There are no protocol-specified SAEs in this study.  All SAEs will be reported to Pfizer 
Safety by the investigator as described in previous sections, and will be handled as SAEs in 
the safety database.

Page 88
8.4.2. Potential Cases of Drug-Induced Liver Injury
Humans exposed to a drug who show no sign of liver injury (as determined by elevations in 
transaminases) are termed “tolerators,” while those who show transient liver injury, but adapt 
are termed “adaptors.”  In some patients, transaminase elevations are a harbinger of a more 
serious potential outcome.  These patients fail to adapt and therefore are "susceptible" to 
progressive and serious liver injury, commonly referred to as drug-induced liver injury 
(DILI).  Patients who experience a transaminase elevation above 3 times the upper limit of 
normal (× ULN) should be monitored more frequently to determine if they are an “adaptor” 
or are “susceptible.”
In the majority of DILI cases, elevations in aspartate aminotransferase (AST) and/or alanine 
aminotransferase (ALT) precede total bilirubin (TBili) elevations (>2 × ULN) by several 
days or weeks.  The increase in TBili typically occurs while AST/ALT is/are still elevated 
above 3 × ULN (ie, AST/ALT and TBili values will be elevated within the same lab sample).  
In rare instances, by the time TBili elevations are detected, AST/ALT values might have 
decreased.  This occurrence is still regarded as a potential DILI.  Therefore, abnormal 
elevations in either AST OR ALT in addition to TBili that meet the criteria outlined below 
are considered potential DILI (assessed per Hy’s law criteria) cases and should always be 
considered important medical events, even before all other possible causes of liver injury 
have been excluded.
The threshold of laboratory abnormalities for a potential DILI case depends on the patient’s 
individual baseline values and underlying conditions.  Patients who present with the 
following laboratory abnormalities should be evaluated further as potential DILI (Hy’s law) 
cases to definitively determine the etiology of the abnormal laboratory values:

Patients with AST/ALT and TBili baseline values within the normal range who 
subsequently present with AST OR ALT values >3 × ULN AND a TBili value 
>2 × ULN with no evidence of hemolysis and an alkaline phosphatase value 
<2 × ULN or not available;

For patients with baseline AST OR ALT OR TBili values above the ULN, the 
following threshold values are used in the definition mentioned above, as needed, 
depending on which values are above the ULN at baseline:

Preexisting AST or ALT baseline values above the normal range: AST or ALT 
values >2 times the baseline values AND >3 × ULN; or >8 × ULN (whichever is 
smaller).

Preexisting values of TBili above the normal range: TBili level increased from 
baseline value by an amount of at least 1 × ULN or if the value reaches 
>3 × ULN (whichever is smaller).
Rises in AST/ALT and TBili separated by more than a few weeks should be assessed 
individually based on clinical judgment; any case where uncertainty remains as to whether it 
represents a potential Hy’s law case should be reviewed with the sponsor.

The patient should return to the investigator site and be evaluated as soon as possible, 
preferably within 48 hours from awareness of the abnormal results.  This evaluation should 
include laboratory tests, detailed history, and physical assessment 
In addition to repeating measurements of AST and ALT and TBili, laboratory tests should 
include albumin, creatine kinase (CK), direct and indirect bilirubin, gamma-glutamyl 
transferase (GGT), prothrombin time (PT)/international normalized ratio (INR), total bile 
acids, alkaline phosphatase and acetaminophen drug and/or protein adduct levels.  
Consideration should also be given to drawing a separate tube of clotted blood and an 
anticoagulated tube of blood for further testing, as needed, for further contemporaneous 
analyses at the time of the recognized initial abnormalities to determine etiology.  A detailed 
history, including relevant information, such as review of ethanol, acetaminophen (either by 
itself or as a co-formulated product in prescription or over-the-counter medications), 
recreational drug, supplement (herbal) use and consumption, family history, sexual history, 
travel history, history of contact with a jaundiced person, surgery, blood transfusion, history 
of liver or allergic disease, and potential occupational exposure to chemicals, should be 
collected.  Further testing for acute hepatitis A, B, C, D, and E infection and liver imaging 
(eg, biliary tract) may be warranted. 
All cases demonstrated on repeat testing as meeting the laboratory criteria of AST/ALT and 
TBili elevation defined above should be considered potential DILI (Hy’s law) cases if no 
other reason for the liver function test (LFT) abnormalities has yet been found.  Such 
potential DILI (Hy’s law) cases are to be reported as SAEs, irrespective of availability 
of all the results of the investigations performed to determine etiology of the LFT 
abnormalities.
A potential DILI (Hy’s law) case becomes a confirmed case only after all results of 
reasonable investigations have been received and have excluded an alternative etiology.
8.4.3. Exposure to the Investigational Product During Pregnancy or Breastfeeding, and 
Occupational Exposure
Exposure to the investigational product under study during pregnancy or breastfeeding and 
occupational exposure are reportable to Pfizer Safety within 24 hours of investigator 
awareness.
8.4.3.1. Exposure During Pregnancy
For both unapproved/unlicensed products and for marketed products, an exposure during 
pregnancy (EDP) occurs if:

A female becomes, or is found to be, pregnant either while receiving or having been 
exposed (eg, because of treatment or environmental exposure) to the investigational 
product; or the female becomes or is found to be pregnant after discontinuing and/or 
being exposed to the investigational product.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 90

An example of environmental exposure would be a case involving direct contact with 
a Pfizer product in a pregnant woman (eg, a nurse reports that she is pregnant and has 
been exposed to chemotherapeutic products).

A male has been exposed (eg, because of treatment or environmental exposure) to the 
investigational product prior to or around the time of conception and/or is exposed 
during his partner’s pregnancy. 

If a patient or patient’s partner becomes or is found to be pregnant during the 
patient’s treatment with the investigational product, the investigator must report this 
information to Pfizer Safety on the CT SAE Report Form and an EDP supplemental 
form, regardless of whether an SAE has occurred.  In addition, the investigator must 
submit information regarding environmental exposure to a Pfizer product in a 
pregnant woman (eg, a patient reports that she is pregnant and has been exposed to a 
cytotoxic product by inhalation or spillage) to Pfizer Safety using the EDP 
supplemental form.  This must be done irrespective of whether an AE has occurred 
and within 24 hours of awareness of the exposure.  The information submitted should 
include the anticipated date of delivery (see below for information related to 
termination of pregnancy).
Follow-up is conducted to obtain general information on the pregnancy and its outcome for 
all EDP reports with an unknown outcome.  The investigator will follow the pregnancy until 
completion (or until pregnancy termination) and notify Pfizer Safety of the outcome as a 
follow-up to the initial EDP supplemental form.  In the case of a live birth, the structural 
integrity of the neonate can be assessed at the time of birth.  In the event of a termination, the 
reason(s) for termination should be specified and, if clinically possible, the structural 
integrity of the terminated fetus should be assessed by gross visual inspection (unless 
pre-procedure test findings are conclusive for a congenital anomaly and the findings are 
reported).
If the outcome of the pregnancy meets the criteria for an SAE (ie, ectopic pregnancy, 
spontaneous abortion, intrauterine fetal demise, neonatal death, or congenital anomaly [in a 
live-born baby, a terminated fetus, an intrauterine fetal demise, or a neonatal death]), the 
investigator should follow the procedures for reporting SAEs.
Additional information about pregnancy outcomes that are reported to Pfizer Safety as SAEs 
follows: 

Spontaneous abortion includes miscarriage and missed abortion.

Neonatal deaths that occur within 1 month of birth should be reported, without regard 
to causality, as SAEs.  In addition, infant deaths after 1 month should be reported as 
SAEs when the investigator assesses the infant death as related or possibly related to 
exposure to the investigational product.

Page 91

Additional information regarding the EDP may be requested by the sponsor.  Further 
follow-up of birth outcomes will be handled on a case-by-case basis (eg, follow-up on 
preterm infants to identify developmental delays).  In the case of paternal exposure, 
the investigator will provide the patient with the Pregnant Partner Release of 
Information Form to deliver to his partner.  The investigator must document in the 
source documents that the patient was given the Pregnant Partner Release of 
Information Form to provide to his partner.
8.4.3.2. Exposure During Breastfeeding
Scenarios of exposure during breastfeeding must be reported, irrespective of the presence of 
an associated SAE, to Pfizer Safety within 24 hours of the investigator’s awareness, using the 
CT SAE Report Form.  An exposure during breastfeeding report is not created when a Pfizer 
drug specifically approved for use in breastfeeding women (eg, vitamins) is administered in 
accord with authorized use.  However, if the infant experiences an SAE associated with such 
a drug’s administration, the SAE is reported together with the exposure during breastfeeding.
8.4.3.3. Occupational Exposure
An occupational exposure occurs when, during the performance of job duties, a person 
(whether a healthcare professional or otherwise) gets in unplanned direct contact with the 
product, which may or may not lead to the occurrence of an AE.
An occupational exposure is reported to Pfizer Safety within 24 hours of the investigator’s 
awareness, using the CT SAE Report Form, regardless of whether there is an associated 
SAE.  Since the information does not pertain to a patient enrolled in the study, the 
information is not recorded on a CRF; however, a copy of the completed CT SAE Report 
Form is maintained in the investigator site file.
8.4.4. Medication Errors 
Other exposures to the investigational product under study may occur in clinical trial settings, 
such as medication errors.

8.4.4.1. Medication Errors
Medication errors may result from the administration or consumption of the investigational 
product by the wrong patient, or at the wrong time, or at the wrong dosage strength. 

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 92
Medication errors include:

Medication errors involving patient exposure to the investigational product;

Potential medication errors or uses outside of what is foreseen in the protocol that do 
or do not involve the participating patient.
Such medication errors occurring to a study participant are to be captured on the medication 
error page of the CRF, which is a specific version of the AE page.
In the event of a medication dosing error, the sponsor should be notified immediately.
Whether or not the medication error is accompanied by an AE, as determined by the 
investigator, the medication error is recorded on the medication error page of the CRF and, if 
applicable, any associated AE(s), serious and non-serious, are recorded on an AE page of the 
CRF.
Medication errors should be reported to Pfizer Safety within 24 hours on a CT SAE Report 
Form only when associated with an SAE.
9. DATA ANALYSIS/STATISTICAL METHODS
Detailed methodology for summary and statistical analyses of the data collected in this study 
will be documented in a statistical analysis plan (SAP), which will be maintained by Pfizer.  
This document may modify the plans outlined in the protocol; however, any major 
modifications of the primary endpoint and/or its analysis will also be reflected in a protocol 
amendment.
This section describes the data analysis and statistical methods for the combination of 
avelumab and axitinib.
9.1. Analysis Sets
9.1.1. Full Analysis Set
The full analysis set includes all patients who receive at least 1 dose of study treatment.
9.1.2. Safety Analysis Set
The safety analysis set includes all patients who receive at least 1 dose of study treatment.  In 
this non-randomized study, the full analysis set and the safety analysis set are identical.
9.1.3. Pharmacokinetics Analysis Set
The PK concentration analysis set is a subset of the safety analysis set and will include 
patients who have at least one post-dose concentration above the lower limit of quantitation 
(LLQ) for avelumab or axitinib.
The PK parameter analysis set is a subset of the safety analysis set and will include treated 
patients who have at least one of the PK parameters of interest for avelumab or axitinib.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 93
9.1.4. Immunogenicity Analysis Set
The immunogenicity analysis set is a subset of the safety analysis set and will include 
patients who have at least one post-dose ADA/NAb sample collected for avelumab.
9.1.5. Biomarker Analysis Set
The biomarker analysis set is a subset of the safety analysis set and will include patients who 
have at least one baseline biomarker assessment. Analysis sets will be defined separately for 
blood-based and tumor tissue-based biomarkers.
9.2. Sample Size Determination
The primary objective is to assess the ORR of avelumab in combination with axitinib in 
patients with advanced or metastatic NSCLC who have received at least one prior 
platinum-containing therapy and in treatment naïve patients with advanced or metastatic UC, 
who are ineligible for cisplatin-containing chemotherapy for their advanced disease.
Approximately 40 patients will be enrolled from each of 2 tumor type cohorts: NSCLC, and 
UC.  Thus, a total of approximately 80 patients will be enrolled. 
With 40 treated patients per tumor type cohort, ORR can be estimated with a maximum 
standard error of 0.079.  Assuming a beta (0.5, 0.5) prior,

NSCLC cohort: if 15 responders (out of 40 patients, ORR of 37.5%) are observed, the 
probability of a true ORR 30% (considered a clinically relevant effect above 
single-agent checkpoint inhibition,39-43 [Section 1.2.2]) will be 80% (85.0%). 

UC cohort: if 19 responders (out of 40 patients, ORR of 47.5%) are observed, the 
probability of a true response rate 40% (considered a clinically relevant effect above 
single-agent checkpoint inhibition25,26 [Section 1.2.1]) will be 80% (83.4%). 
Table 8 provides the exact 95% confidence intervals for ORR based on different observed 
number of responders in a given tumor type cohort.

9.3. Efficacy Analysis 
All efficacy analyses will be performed based on the full analysis set for each tumor type 
cohort separately.
9.3.1. Analysis of the Primary Endpoint
The primary endpoint is confirmed OR based on Investigator assessment per RECIST v1.1. 
OR is defined as a CR or PR per RECIST v 1.1 from the first dose of study treatment until 
disease progression or death due to any cause.  Both CR and PR must be confirmed by repeat 
assessments performed no less than 4 weeks after the criteria for response are first met.  ORR 
is defined as the proportion of patients with a confirmed CR or confirmed PR based on 
Investigator’s assessment per RECIST v 1.1.  Confirmed responses are those that persist on 
repeat tumor assessments for at least 4 weeks after initial documentation or response.  
Otherwise, the patient will be counted as a non-responder in the assessment of ORR.  
Additionally, patients with inadequate data for tumor assessment (eg, no baseline assessment 
or no follow-up assessments) will be considered as non-responders in the assessment of 
ORR.  The two-sided exact 95% CIs for ORR will be calculated.
9.3.2. Analysis of the Secondary Efficacy Endpoints
PFS is defined as the time from first dose of study treatment (ie, start date) to the date of 
disease progression by RECIST v 1.1 or death due to any cause, whichever occurs first.  PFS 
data will be censored on the date of the last adequate tumor assessment for patients who do 
not have an event (PD or death), for patients who start new anti-cancer treatment prior to an 
event, or for patients with an event after two or more missing tumor assessments.  Patients 
who do not have an adequate baseline tumor assessment or who do not have any adequate 
post-baseline tumor assessments will be censored on the date of first dose of study treatment 
unless death occurred on or before the time of the second planned tumor assessment in which 
case the death will be considered an event.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 95
TTR is defined for patients with confirmed objective response (CR or PR) as the time from 
the first dose of study treatment to the first documentation of objective tumor response.
DR is defined for patients with confirmed objective response (CR or PR) as the time from the 
first documentation of objective tumor response to the first documentation of objective tumor 
progression or to death due to any cause, whichever occurs first.
OS is defined as the time from the first dose of study treatment to the date of death.  Patients 
without an event (death) will be censored at the date of last contact.
TTR will be summarized using simple descriptive statistics (eg, median and range).  DR, 
PFS, and OS will be analyzed using Kaplan-Meier methods.  Point estimates will be 
presented with 95% CIs.  In addition, progression date, death date, date of first response, and 
last tumor assessment date will be listed, along with BOR, TTR, DR, PFS and OS.
9.4. Analysis of Pharmacokinetics and Pharmacodynamics
9.4.1. Analysis of Pharmacokinetics of Investigational Products
PK data analyses will include descriptive summary statistics (n, mean, SD, coefficient of 
variation (CV), median, minimum, maximum, geometric mean and its associated CV) of the 
pre-dose trough (Ctrough) and post-dose (Cmax) concentrations for each investigational product 
by cycle, day and by dose level.
Other PK parameters may be determined if deemed appropriate.  The summary data may be 
compared with the historical data of avelumab and axitinib as single agents to assess the 
effect of avelumab on the PK of axitinib and the effect of axitinib on the PK of avelumab.  
The analysis and population modeling analysis report (PMAR), if performed, will be outlined 
in the statistical analysis plan (SAP).
The trough concentrations for avelumab and axitinib will be plotted versus time for each dose 
using a box whisker plot by cycle and day in order to assess the attainment of steady state.
9.4.2. Population Pharmacokinetic Analysis or Pharmacokinetic/Pharmacodynamic 
(PK/Pharmacodynamic) Modeling
Pharmacokinetic and pharmacodynamic data from this study may be analyzed using 
modeling approaches and may also be pooled with data from other studies to investigate any 
association between avelumab and axitinib exposure and biomarkers or significant safety 
endpoints.  The results of these analyses, if performed, may be reported separately.
9.4.3. Analysis of Immunogenicity Data of Avelumab
ADA and NAb data will be listed and summarized for each dosing interval for avelumab.  
The percentage of patients with positive ADA and NAb will each be summarized by cohort 
and for all cohorts combined.  For patients with positive ADA, the magnitude (titer), time of 
onset, and duration of ADA response will also be described, if data permit.  The effect of 
ADA on avelumab concentrations and pharmacokinetics will be evaluated, if data permit.

Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 96
9.5. Analyses for Secondary 
 Biomarker Endpoints
For continuous measurement biomarker results, summary statistics (eg, the mean, standard 
deviation, median, percent of coefficient of variation, and minimum/maximum levels) will be 
determined at baseline and on-treatment/end of treatment time points, as appropriate.  
Appropriate change from baseline measurements will be provided.
For discrete measurement biomarkers (eg, tumor marker status), frequencies and percentages 
of categorical biomarker measures will be determined at baseline and on-treatment/end of 
treatment time points.  Shift tables may also be provided.
Data from biomarker assays may be analyzed using graphical methods and descriptive 
statistics such as Fisher’s exact test, Wilcoxon rank-sum test, Kaplan-Meier estimates, and 
linear regression as appropriate.  The statistical approaches will explore the correlations of 
biomarker results with pharmacokinetic parameters and measures of anti-tumor efficacy, 
such as tumor response and progression free survival.
9.6. Safety Analysis
9.6.1. Adverse Events
AEs will be graded by the investigator according to the CTCAE version 4.03 and coded 
using the Medical Dictionary for Regulatory Activities (MedDRA).  The focus of AE 
summaries will be on Treatment Emergent Adverse Events, those with initial onset or 
increasing in severity after the first dose of study treatment.  The number and percentage of 
patients who experienced any AE, SAE, treatment-related AE, and treatment-related SAE 
will be summarized according to worst toxicity grades. 
9.6.2. Laboratory Test Abnormalities
The laboratory results will be graded according to the CTCAE version 4.03 severity grade 
whenever applicable.  The number and percentage of patients who experienced laboratory 
test abnormalities will be summarized according to worst toxicity grade observed for each 
laboratory test.
For laboratory tests without CTCAE grade definitions, results will be categorized as normal, 
abnormal, or not done.
Shift tables will be provided to examine the distribution of laboratory toxicities.
9.6.3. Electrocardiogram
Baseline ECG measurements will be summarized by tumor type cohort.  Interval 
measurements from clinically indicated on-treatment ECGs will be included in the outlier 
analysis (categorical analysis) as individual values obtained at unscheduled time points.
QT intervals will be corrected for heart rate (QTc) using standard correction factors 
[ie, Fridericia’s (default correction), Bazett’s, and possibly a study specific factor, as 
appropriate].  Data will be summarized and listed for QT, HR, RR, PR, QRS, and QTc.

Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 97
Descriptive statistics (n, mean, median, standard deviation, minimum, and maximum) will be 
used to summarize the absolute corrected QT interval.
9.7. Analysis of Other Endpoints
Descriptive statistics will be used to summarize all patient characteristics, treatment 
administration/compliance, safety parameters, and biomarkers.  Data will also be displayed 
graphically, where appropriate. 
9.8. Interim Analysis
No formal interim analysis will be conducted for this study.  However, as this is an 
open-label, non-randomized study, the Sponsor may conduct unblinded reviews of the data 
during the course of the study for the purpose of efficacy and safety assessment, facilitating 
PK/Pharmacodynamic modeling, and/or to support clinical development.
9.9. Data Monitoring Committee
An external independent Data Safety Monitoring Committee will not be established for the 
study.  For the purpose of this protocol, Pfizer procedures for periodic safety review will be 
applied by an internal safety review team with medical and statistical capabilities to review 
individual and summary data collected in the safety and clinical databases.  Procedures 
include:

Surveillance for SAEs according to regulatory guidelines;

Discussions between the investigators and the sponsor of AEs and laboratory tests 
alterations seen at each dose level will be performed in an ongoing manner at regular 
teleconferences and/or meetings to determine the safety profile and risk/benefit ratio 
and decide if further enrollment is appropriate.
10. QUALITY CONTROL AND QUALITY ASSURANCE
Pfizer or its agent will conduct periodic monitoring visits during study conduct to ensure that 
the protocol and Good Clinical Practices (GCPs) are being followed.  The monitors may 
review source documents to confirm that the data recorded on CRFs are accurate.  The 
investigator and institution will allow Pfizer monitors/auditors or its agents and appropriate 
regulatory authorities direct access to source documents to perform this verification.  This 
verification may also occur after study completion.
During study conduct and/or after study completion, the investigator site may be subject to 
review by the IRB/EC, and/or to quality assurance audits performed by Pfizer, or companies 
working with or on behalf of Pfizer, and/or to inspection by appropriate regulatory 
authorities.
The investigator(s) will notify Pfizer or its agents immediately of any regulatory inspection 
notification in relation to the study.  Furthermore, the investigator will cooperate with Pfizer 
or its agents to prepare the investigator site for the inspection and will allow Pfizer or its 
agent, whenever feasible, to be present during the inspection.  The investigator site and 

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 98
investigator will promptly resolve any discrepancies that are identified between the study 
data and the patient's medical records.  The investigator will promptly provide copies of the 
inspection findings to Pfizer or its agent.  Before response submission to the regulatory 
authorities, the investigator will provide Pfizer or its agents with an opportunity to review 
and comment on responses to any such findings.
It is important that the investigator(s) and their relevant personnel are available during the 
monitoring visits and possible audits or inspections and that sufficient time is devoted to the 
process.
11. DATA HANDLING AND RECORD KEEPING
11.1. Case Report Forms/Electronic Data Record
As used in this protocol, the term CRF should be understood to refer to either a paper form or 
an electronic data record or both, depending on the data collection method used in this study.
A CRF is required and should be completed for each included patient.  The completed 
original CRFs are the sole property of Pfizer and should not be made available in any form to 
third parties, except for authorized representatives of Pfizer or appropriate regulatory 
authorities, without written permission from Pfizer.
The investigator has ultimate responsibility for the collection and reporting of all clinical, 
safety, and laboratory data entered on the CRFs and any other data collection forms (source 
documents) and ensuring that they are accurate, authentic/original, attributable, complete, 
consistent, legible, timely (contemporaneous), enduring, and available when required.  The 
CRFs must be signed by the investigator or by an authorized staff member to attest that the 
data contained on the CRFs are true.  Any corrections to entries made in the CRFs or source 
documents must be dated, initialed, and explained (if necessary) and should not obscure the 
original entry. 
In most cases, the source documents are the hospital or the physician patient chart.  In these 
cases, data collected on the CRFs must match the data in those charts. 
In some cases, the CRF may also serve as the source document.  In these cases, a document 
should be available at the investigator site and at Pfizer that clearly identifies those data that 
will be recorded on the CRF, and for which the CRF will stand as the source document.
11.2. Record Retention
To enable evaluations and/or inspections/audits from regulatory authorities or Pfizer, the 
investigator agrees to keep records, including the identity of all participating patients 
(sufficient information to link records, eg, CRFs and hospital records), all original signed 
informed consent documents, copies of all CRFs, safety reporting forms, source documents, 
and detailed records of treatment disposition, and adequate documentation of relevant 
correspondence (eg, letters, meeting minutes, and telephone call reports).  The records should 
be retained by the investigator according to the ICH guidelines, according to local 
regulations, or as specified in the clinical study agreement (CSA), whichever is longer.

MSB0010718C, AG-013736 
B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 99
If the investigator becomes unable for any reason to continue to retain study records for the 
required period (eg, retirement, relocation), Pfizer should be prospectively notified.  The 
study records must be transferred to a designee acceptable to Pfizer, such as another 
investigator, another institution, or an independent third party arranged by Pfizer. 
Investigator records must be kept for a minimum of 15 years after completion or 
discontinuation of the study or for longer if required by applicable local regulations.
The investigator must obtain Pfizer's written permission before disposing of any records, 
even if retention requirements have been met.
12. ETHICS
12.1. Institutional Review Board/Ethics Committee
It is the responsibility of the investigator to have prospective approval of the study protocol, 
protocol amendments, informed consent documents, and other relevant documents, 
eg, recruitment advertisements, if applicable, from the IRB/EC.  All correspondence with the 
IRB/EC should be retained in the investigator file.  Copies of IRB/EC approvals should be 
forwarded to Pfizer.
The only circumstance in which an amendment may be initiated prior to IRB/EC approval is 
where the change is necessary to eliminate apparent immediate hazards to the patients.  In 
that event, the investigator must notify the IRB/EC and Pfizer in writing immediately after 
the implementation.
12.2. Ethical Conduct of the Study
The study will be conducted in accordance with the protocol, legal and regulatory 
requirements, and the general principles set forth in the International Ethical Guidelines for 
Biomedical Research Involving Human Patients (Council for International Organizations of 
Medical Sciences 2002), ICH Guideline for Good Clinical Practice, and the Declaration of 
Helsinki.
12.3. Patient Information and Consent
All parties will ensure protection of patient personal data and will not include patient names 
or other identifiable data in any reports, publications, or other disclosures, except where 
required by law. 
When study data are compiled for transfer to Pfizer and other authorized parties, patient 
names, addresses, and other identifiable data will be replaced by numerical codes based on a 
numbering system provided by Pfizer in order to de-identify study patients.  The investigator 
site will maintain a confidential list of patients who participated in the study, linking each 
patient’s numerical code to his or her actual identity.  In case of data transfer, Pfizer will 
maintain high standards of confidentiality and protection of patients’ personal data consistent 
with applicable privacy laws.

The informed consent documents and any patient recruitment materials must be in 
compliance with ICH GCP, local regulatory requirements, and legal requirements, including 
applicable privacy laws.
The informed consent documents used during the informed consent process and any patient 
recruitment materials must be reviewed and approved by Pfizer, approved by the IRB/EC 
before use, and available for inspection.
The investigator must ensure that each study patient is fully informed about the nature and 
objectives of the study and possible risks associated with participation. 
The investigator, or a person designated by the investigator, will obtain written informed 
consent from each patient before any study-specific activity is performed.  The investigator 
will retain the original of each patient's signed consent document.
12.4. Reporting of Safety Issues and Serious Breaches of the Protocol or ICH GCP
In the event of any prohibition or restriction imposed (ie, clinical hold) by an applicable 
regulatory authority in any area of the world, or if the investigator is aware of any new 
information that might influence the evaluation of the benefits and risks of the investigational 
product, Pfizer should be informed immediately. 
In addition, the investigator will inform Pfizer immediately of any urgent safety measures 
taken by the investigator to protect the study patients against any immediate hazard, and of 
any serious breaches of this protocol or of ICH GCP that the investigator becomes aware of.
13. DEFINITION OF END OF TRIAL
13.1. End of Trial in a Member State 
End of trial in a Member State of the European Union is defined as the time at which it is 
deemed that a sufficient number of patients have been recruited and completed the study as 
stated in the regulatory application (ie, clinical trial application [CTA]) and ethics application 
in the Member State.  Poor recruitment (recruiting less than the anticipated number in the 
CTA) by a Member State is not a reason for premature termination but is considered a 
normal conclusion to the study in that Member State.
13.2. End of Trial in All Other Participating Countries 
End of trial in all other participating countries is defined as last patient last visit (LSLV). 
14. SPONSOR DISCONTINUATION CRITERIA
Premature termination of this study may occur because of a regulatory authority decision, 
change in opinion of the IRB/EC, or investigational product safety problems, or at the 
discretion of Pfizer.  In addition, Pfizer retains the right to discontinue development of 
avelumab in combination with axitinib at any time.

If a study is prematurely terminated, Pfizer will promptly notify the investigator.  After 
notification, the investigator must contact all participating patients and the hospital pharmacy 
(if applicable) within one month.  As directed by Pfizer, all study materials must be collected 
and all CRFs completed to the greatest extent possible.
15. PUBLICATION OF STUDY RESULTS
15.1. Communication of Results by Pfizer
Pfizer fulfills its commitment to publicly disclose clinical trial results through posting the 
results of studies on www.clinicaltrials.gov (ClinicalTrials.gov), the European Clinical Trials 
Database (EudraCT), and/or www.pfizer.com, and other public registries in accordance with 
applicable local laws/regulations. 
In all cases, study results are reported by Pfizer in an objective, accurate, balanced, and 
complete manner and are reported regardless of the outcome of the study or the country in 
which the study was conducted.
www.clinicaltrials.gov
Pfizer posts clinical trial US Basic Results on www.clinicaltrials.gov for Pfizer-sponsored 
interventional studies (conducted in patients) that evaluate the safety and/or efficacy of a 
Pfizer product, regardless of the geographical location in which the study is conducted.  US 
Basic Results are submitted for posting within 1 year of the primary completion date (PCD) 
for studies in adult populations or within 6 months of the PCD for studies in pediatric 
populations.
PCD is defined as the date that the final patient was examined or received an intervention for 
the purposes of final collection of data for the primary outcome, whether the clinical study 
concluded according to the prespecified protocol or was terminated.
EudraCT
Pfizer posts European Union (EU) Basic Results on EudraCT for all Pfizer-sponsored 
interventional studies that are in scope of EU requirements.  EU Basic Results are submitted 
for posting within 1 year of the PCD for studies in adult populations or within 6 months of 
the PCD for studies in pediatric populations.
www.pfizer.com
Pfizer posts Public Disclosure Synopses (clinical study report synopses in which any data 
that could be used to identify individual patients has been removed) on www.pfizer.com for 
Pfizer-sponsored interventional studies at the same time the US Basic Results document is 
posted to www.clinicaltrials.gov.

15.2. Publications by Investigators
Pfizer supports the exercise of academic freedom and has no objection to publication by the 
principal investigator (PI) of the results of the study based on information collected or 
generated by the PI, whether or not the results are favorable to the Pfizer product.  However, 
to ensure against inadvertent disclosure of confidential information or unprotected 
inventions, the investigator will provide Pfizer an opportunity to review any proposed 
publication or other type of disclosure of the results of the study (collectively, “publication”) 
before it is submitted or otherwise disclosed.
The investigator will provide any publication to Pfizer at least 30 days before it is submitted 
for publication or otherwise disclosed.  If any patent action is required to protect intellectual 
property rights, the investigator agrees to delay the disclosure for a period not to exceed an 
additional 60 days.
The investigator will, on request, remove any previously undisclosed confidential 
information before disclosure, except for any study- or Pfizer product-related information 
necessary to the appropriate scientific presentation or understanding of the study results.
If the study is part of a multicenter study, the investigator agrees that the first publication is 
to be a joint publication covering all investigator sites, and that any subsequent publications 
by the PI will reference that primary publication.  However, if a joint manuscript has not 
been submitted for publication within 12 months of completion or termination of the study at 
all participating sites, the investigator is free to publish separately, patient to the other 
requirements of this section.
For all publications relating to the study, the institution will comply with recognized ethical 
standards concerning publications and authorship, including Section II - “Ethical 
Considerations in the Conduct and Reporting of Research” of the Uniform Requirements for 
Manuscripts Submitted to Biomedical Journals, http://www.icmje.org/index.html#authorship, 
established by the International Committee of Medical Journal Editors.
Publication of study results is also provided for in the CSA between Pfizer and the 
institution.  In this section entitled Publications by Investigators, the defined terms shall have 
the meanings given to them in the CSA.
If there is any conflict between the CSA and any attachments to it, the terms of the CSA 
control.  If there is any conflict between this protocol and the CSA, this protocol will control 
as to any issue regarding treatment of study patients, and the CSA will control as to all other 
issues.

Appendix 3. Treatment Recommendations for Symptoms of Avelumab 
Infusion-Related Reactions
The following treatment recommendations for symptoms of avelumab infusion-related
reactions may be modified based on local treatment standards and guidelines, as appropriate.
For Grade 1 Symptoms: (Mild reaction; infusion interruption not indicated; intervention not 
indicated)

Decrease the avelumab infusion rate by 50% and monitor closely for any worsening.

Remain at bedside and monitor patient until recovery from symptoms.
For Grade 2 Symptoms: (Moderate reaction; Therapy or infusion interruption indicated but 
responds promptly to symptomatic treatment (eg, antihistamines, NSAIDs, narcotics, 
IV fluids); prophylactic medications indicated for 24 hours).

Temporarily discontinue avelumab infusion.

Treat based on emerging symptoms.  Treatment may include:

Normal saline IV;

H1 blockers, such as diphenhydramine 25 to 50 mg IV (or equivalent);

H2 blockers, such as ranitidine 50 mg IV (or equivalent);

Corticosteroids, such as hydrocortisone 100 to 500 mg IV (or equivalent);

Bronchodilators.

Remain at bedside and monitor patient until resolution of symptoms.

Resume avelumab infusion at 50% of previous rate as soon as infusion related 
reaction has resolved or decreased to at least Grade 1 in severity, and monitor closely
for any recurrence or worsening.
For Grade 3 or Grade 4 Symptoms: (Severe reaction; Grade 3: prolonged [eg, not rapidly
responsive to symptomatic medication and/or brief interruption of infusion]; recurrence of
symptoms following initial improvement; hospitalization indicated for clinical sequelae

Appendix 4. Response Evaluation Criteria in Solid Tumors Version 1.1
Adapted from E.A. Eisenhauer, et al.  New response evaluation criteria in solid tumours: 
Revised RECIST guideline (version 1.1).  European Journal of Cancer 45 (2009) 228–247. 
CATEGORIZING LESIONS AT BASELINE
Measurable Lesions 

Lesions that can be accurately measured in at least one dimension.

Lesions with longest diameter twice the slice thickness and at least 10 mm or greater 
when assessed by CT or MRI (slice thickness 5-8 mm).

Lesions with longest diameter at least 20 mm when assessed by Chest X-ray. 

Superficial lesions with longest diameter 10 mm or greater when assessed by caliper. 

Malignant lymph nodes with the short axis 15 mm or greater when assessed by CT.
NOTE: The shortest axis is used as the diameter for malignant lymph nodes, longest 
axis for all other measurable lesions. 
Non-measurable disease 
Non-measurable disease includes lesions too small to be considered measurable (including 
nodes with short axis between 10 and 14.9 mm) and truly non-measurable disease such as
pleural or pericardial effusions, ascites, inflammatory breast disease, leptomeningeal disease, 
lymphangitic involvement of skin or lung, clinical lesions that cannot be accurately measured 
with calipers, abdominal masses identified by physical exam that are not measurable by 
reproducible imaging techniques.

Bone disease: Bone disease is non-measurable with the exception of soft tissue 
components that can be evaluated by CT or MRI and meet the definition of 
measurability at baseline. 

Previous local treatment: A previously irradiated lesion (or lesion patiented to other 
local treatment) is non-measurable unless it has progressed since completion of 
treatment.
Normal sites

Cystic lesions: Simple cysts should not be considered as malignant lesions and should 
not be recorded either as target or non-target disease.  Cystic lesions thought to 
represent cystic metastases can be measurable lesions, if they meet the specific 
definition above.  If non-cystic lesions are also present, these are preferred as target 
lesions.

B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 116

Normal nodes: Nodes with short axis <10 mm are considered normal and should not 
be recorded or followed either as measurable or non-measurable disease.
RECORDING TUMOR ASSESSMENTS 
All sites of disease must be assessed at baseline.  Baseline assessments should be done as 
close as possible prior to study start.  For an adequate baseline assessment, all required scans 
must be done within 28 days prior to treatment and all disease must be documented 
appropriately.  If baseline assessment is inadequate, subsequent statuses generally should be 
indeterminate. 
Target lesions
All measurable lesions up to a maximum of 2 lesions per organ, 5 lesions in total, 
representative of all involved organs, should be identified as target lesions at baseline.  
Target lesions should be selected on the basis of size (longest lesions) and suitability for 
accurate repeated measurements.  Record the longest diameter for each lesion, except in the 
case of pathological lymph nodes for which the short axis should be recorded.  The sum of 
the diameters (longest for non-nodal lesions, short axis for nodal lesions) for all target lesions 
at baseline will be the basis for comparison to assessments performed on study. 
If two target lesions coalesce the measurement of the coalesced mass is used.  If a large target 
lesion splits, the sum of the parts is used.
Measurements for target lesions that become small should continue to be recorded.  If a 
target lesion becomes too small to measure, 0 mm should be recorded if the lesion is 
considered to have disappeared; otherwise a default value of 5 mm should be recorded.
NOTE: When nodal lesions decrease to <10 mm (normal), the actual measurement 
should still be recorded.
Non-target disease 
All non-measurable disease is non-target.  All measurable lesions not identified as target 
lesions are also included as non-target disease.  Measurements are not required but rather 
assessments will be expressed as ABSENT, INDETERMINATE, PRESENT/NOT 
INCREASED, INCREASED.  Multiple non-target lesions in one organ may be recorded as a 
single item on the case report form (eg, ‘multiple enlarged pelvic lymph nodes’ or ‘multiple 
liver metastases’).
OBJECTIVE RESPONSE STATUS AT EACH EVALUATION 
Disease sites must be assessed using the same technique as baseline, including consistent 
administration of contrast and timing of scanning.  If a change needs to be made the case 
must be discussed with the radiologist to determine if substitution is possible.  If not, 
subsequent objective statuses are indeterminate.

Target disease

Complete Response (CR): Complete disappearance of all target lesions with the 
exception of nodal disease.  All target nodes must decrease to normal size (short axis 
<10 mm).  All target lesions must be assessed.

Partial Response (PR): Greater than or equal to 30% decrease under baseline of the 
sum of diameters of all target measurable lesions.  The short diameter is used in the 
sum for target nodes, while the longest diameter is used in the sum for all other target 
lesions.  All target lesions must be assessed. 

Stable: Does not qualify for CR, PR or Progression.  All target lesions must be 
assessed.  Stable can follow PR only in the rare case that the sum increases by less 
than 20% from the nadir, but enough that a previously documented 30% decrease no 
longer holds. 

Objective Progression (PD): 20% increase in the sum of diameters of target 
measurable lesions above the smallest sum observed (over baseline if no decrease in 
the sum is observed during therapy), with a minimum absolute increase of 5 mm. 

Indeterminate.  Progression has not been documented, and 

One or more target measurable lesions have not been assessed; 
or

Assessment methods used were inconsistent with those used at baseline;
or

One or more target lesions cannot be measured accurately (eg, poorly visible 
unless due to being too small to measure);
or

One or more target lesions were excised or irradiated and have not reappeared or 
increased. 
Non-target disease

CR: Disappearance of all non-target lesions and normalization of tumor marker 
levels.  All lymph nodes must be ‘normal’ in size (<10 mm short axis).

Non-CR/Non-PD: Persistence of any non-target lesions and/or tumor marker level 
above the normal limits.

B9991027
Final Protocol Amendment 1, 07 March 2018
PFIZER CONFIDENTIAL
Page 118

PD: Unequivocal progression of pre-existing lesions.  Generally the overall tumor 
burden must increase sufficiently to merit discontinuation of therapy.  In the presence 
of SD or PR in target disease, progression due to unequivocal increase in non-target 
disease should be rare. 

Indeterminate: Progression has not been determined and one or more non-target sites 
were not assessed or assessment methods were inconsistent with those used at 
baseline.
New Lesions 
The appearance of any new unequivocal malignant lesion indicates PD.  If a new lesion is 
equivocal, for example due to its small size, continued assessment will clarify the etiology.  
If repeat assessments confirm the lesion, then progression should be recorded on the date of 
the initial assessment.  A lesion identified in an area not previously scanned will be 
considered a new lesion.
Supplemental Investigations
If CR determination depends on a residual lesion that decreased in size but did not disappear 
completely, it is recommended the residual lesion be investigated with biopsy or fine needle 
aspirate.  If no disease is identified, objective status is CR.
If progression determination depends on a lesion with an increase possibly due to necrosis, 
the lesion may be investigated with biopsy or fine needle aspirate to clarify status. 
Objective/Subjective Progression
Patients requiring discontinuation of treatment without objective evidence of disease 
progression should not be reported as PD on tumor assessment CRFs.  This should be 
indicated on the end of treatment CRF as off treatment due to Global Deterioration of Health 
Status.  Every effort should be made to document objective progression even after 
discontinuation of treatment. 
When both target and non-target lesions are present, individual assessments will be recorded 
separately.  Determination of tumor response at each assessment is summarized in table 
Table 9.

Determination of Best Overall Response
The best overall response is the best response recorded from the start of the treatment until 
disease progression (taking as reference for progressive disease the smallest sum on study).  
For CR and PR, the patient’s best response assignment will depend on the achievement of 
both measurement and confirmation criteria.  CR and PR must be confirmed by 
2 measurements at least 4 weeks apart.  In the case of SD, follow-up measurements must 
have met the SD criteria at least once after study entry at a minimum interval of 8 weeks.
