Phase 
Phase 2 
Methodology 
Randomized Phase 2 trial for a total of 20 patients per cohort 
Study Duration 
3640 months 
Study Center(s) 
Multicenter; Columbia University Medical Center, and Memorial Sloan 
Kettering Cancer Center 
Objectives 
To compare the number of CD8+ T-cells within the tumor with 
neoadjuvant atezolizumab alone or in combination with PEGPH20 or 
other therapies (TBD) at time of surgery. 
To estimate the 18-month recurrence free survival rate and overall 
survival in each arm. 
Number of Patients 
Approximately 20 patients are planned for enrollment per cohort. 
Diagnosis and Main 
Inclusion Criteria 
Resectable pancreatic adenocarcinoma 
Study Product, Dose, 
Route, Regimen 
Cohort 1: Atezolizumab 840mg IV every 2 weeks for 2 doses prior to 
surgery and 4 doses after surgery.  
Cohort 2: Atezolizumab 840mg IV every 2 weeks for 2 doses prior to 
surgery and 4 doses after surgery in combination with PEGPH20 
3g/kg IV twice weekly for 3 weeks prior to surgery and once weekly for 
3 weeks (of 28 day cycle) for two cycles after surgery. (Additional 
cohorts to be added TBD) 
Duration of 
administration 
3 weeks prior and 8 weeks after surgery with study drugs 
6 months with adjuvant chemotherapy 
Reference therapy 
Atezolizumab therapy and historical matched controls who did not
receive therapy 
Statistical 
Methodology 
Primary endpoint is change in number of intratumoral CD8+ T-cells 
at time of surgery between treatment arm(s) compared to the 
atezolizumab arm. Group sample sizes of 17 achieve at least 80% 
power to detect a difference of 1 SD with a significance level (alpha) of 
0.05 using a two-sided two-sample t-test.

Pancreas adenocarcinoma (PDA) is an aggressive cancer for which little progress has 
been made over the past decades with 5-year survival at 7%, and is projected to be the 
second leading cause of cancer-related death in the United States in 2030 (Rahib et al. 
2014; Siegel et al. 2016). Even for early stage disease, recurrence is high. Although 
recent combination therapies for metastatic PDA have improved survival by up to 
5 months, the overall prognosis remains little changed and novel therapies are 
desperately needed (Conroy et al. 2011; Von Hoff et al. 2013). The majority of patients 
diagnosed with PDA either have locally advanced (~ 30%) or distant (~ 50%) disease, 
for which chemotherapy is the mainstay of treatment (Howlader et al. 2017). Of those 
that receive surgery followed by adjuvant chemotherapy, the median overall survival 
remains poor (20.1 to 54.4 months) (Neoptolemos et al. 2004; Oettle et al. 2007; 
Regine et al. 2008; Neoptolemos et al. 2010; Howlader et al. 2017; Conroy et al. 2008). 
Negative margins, smaller tumor size, and lack of lymph node involvement result in 
improved prognosis (Allison et al. 1998; Sohn et al. 2000; Howard et al. 2006). Patients 
with metastasis to visceral organs, peritoneum, or lymph nodes that are beyond the field 
of resection derive no benefit from surgery. 
Of the newly diagnosed patients, nearly 15% are considered to be candidates for 
immediate surgical resection (Vincent et al. 2011). Despite resection, disease recurs in a 
majority of these patients and the median disease- free survival is 6.7 months (Oettle 
et al. 2013). Addition of capecitabine to gemcitabine has improved median overall 
survival from 25.5 to 28.0 months (HR 0.82, p=0.032) compared to those patients treated 
with gemcitabine alone (Neoptolemos et al. 2017). However, preliminary experience 
with use of this regimen in the United States has posed to be a challenge as most 
patients are unable to tolerate the doses used in the European ESPAC-4 trial and 
require frequent dose reductions or schedule modifications. PRODIGE 24, a large 
randomized phase 3 study compared mFOLFIRINOX to gemcitabine monotherapy in the 
adjuvant setting and demonstrated a median overall survival benefit of 54.4 months 
compared to 35.0 months, respectively. The median disease free survival was 
21.6 months in the mFOLFIRINOX arm compared to 12.8 months in the gemcitabine 
monotherapy arm (Andre et al. 2018; Conroy et al. 2018). The reported 18-month overall 
survival (OS) is 67% with adjuvant gemcitabine in combination with capecitabine which is 
similar to the 63% reported when gemcitabine and oxaliplatin were tested in the 
neoadjuvant setting (O’Reilly et al. 2016). Although mFOLFIRINOX yielded impressive 
results, patients enrolled onto the study had a better performance status to withstand 
mFOLFIRINOX.  
A majority of resectable patients likely have micrometastatic disease at time of diagnosis 
and therefore benefit from adjuvant chemotherapy. It is in this setting that

immunotherapy either alone or in combination with agents that disrupt the 
immunosuppressive tumor microenvironment (TME) are likely to be effective in 
controlling micro metastatic foci of disease. Effective treatments to at least prolong the 
disease-free duration if not increasing the cure rate, are desperately needed for this 
fatal disease.

STUDY OBJECTIVES 
2.1 
PRIMARY OBJECTIVE 
To compare the number of CD8+ T cells within the tumor after neoadjuvant 
atezolizumab alone or in combination with PEGPH20 or other therapies at time of 
surgery. 
2.2 
SECONDARY OBJECTIVE 
a) To estimate the 18-month survival rate and overall survival in patients treated with 
atezolizumab vs atezolizumab + PEGPH20 or other therapies followed by surgery 
and adjuvant therapy. 
b) To determine the R0 resection rates with atezolizumab vs atezolizumab + 
PEGPH20 or other therapies administered in the neoadjuvant setting. 
c) 
To determine the safety profile with atezolizumab vs atezolizumab + PEGPH20 or 
other therapies followed by surgery and adjuvant therapy. 
d) To evaluate Ca 19-9 biomarker responses to atezolizumab with or without 
PEGPH20 or other therapies in the neoadjuvant setting. 
e) To evaluate patterns of failure following neoadjuvant atezolizumab with or without 
PEGPH20 or other therapies and surgery.

BACKGROUND 
Presently, surgical resection offers the only therapeutic means of cure. However only 
15%-20% of patients are found to have resectable disease at time of initial diagnosis. Of 
the patients who undergo curative surgery, most will relapse and eventually succumb to 
the disease. 5-year survival rates for node-negative and -positive disease at time of 
pancreatic duodenectomy are 25%-30% and 10%, respectively (Trede et al 1990; 
Geer and Brennan 1993; Yeo et al. 1995). 
3.1 
IMMUNOTHERAPY IN PDA 
Multiple studies have shown that genetic mutations in tumor DNA can lead to the 
expression of antigenic peptides which can drive the anti-tumor therapeutic immune 
response unleashed by immune checkpoint inhibitors (Snyder et al. 2014; Azuma et al 
2014; Rizvi et al. 2015). Neoantigen-specific lymphocytes can be detected in peripheral 
blood samples and their levels correlate with disease response to anti-programmed 
death-1(PD-1) therapy. PDAs are characterized by a moderate mutational burden 
(averaging 67 coding mutations) comparable to other solid tumors (Brahmer et al. 2010; 
Mu et al. 2011; Brahmer et al. 2012). However, early phase monotherapy anti-CTLA-4 
and anti-programmed death ligand-1(PD-L1) antibody trials in patients with metastatic 
and locally advanced PDA demonstrated limited activity (Royal et al. 2010; Brahmer et 
al. 2012). Interim results of a multicenter, phase 1 trial involving the anti-PD-L1 mAb, 
durvalumab, were presented at European Society for Medical Oncology (ESMO) and 
showed a disease control rate of 21% (6 of 29 patients) in PDA patients, two of whom 
achieved a partial response (Segal et al. 2014). Although PDA has been considered a 
non-immunogenic cancer, these studies demonstrate that PDA can respond to 
immunotherapy and that further study is warranted. 
A leading explanation for the lack of efficacy of single-agent immunotherapy is the 
highly immunosuppressive stroma that envelopes most malignant cells. PDAs contain 
very few effector T cells, and in surgically resected tumors a higher number of tumor-
infiltrating lymphocytes (TILs) correlates with improved survival (Fukunaga et al. 2004). 
Untreated PDAs are characterized by low PD-L1 expression, where only 12% of tumors 
analyzed expressed membranous staining of PD-L1 in more than 5% of neoplastic cells 
(Soares et al. 2015). Interestingly, a retrospective study evaluating resected PDA tissue 
identified that PD-L1 staining inversely correlated with survival and CD8+ T-cell

infiltration (Nomi et al. 2007). This suggests that targeting PD-L1 may unmask at least 
part of the immunosuppression function within PDA. Furthermore, evaluation of a 
monoclonal agonist antibody targeting CD40, in combination with gemcitabine, 
detected four partial responses in 22 patients with advanced PDA while other patients 
experienced decreased fluorodeoxyglucose (FDG) uptake within their primary and/or 
metastatic lesions on positron emission tomography (PET)/computed tomography (CT) 
scans (Beatty et al. 2013). Furthermore, recent reports indicated that immunotherapy 
appears to be effective in patients with microsatellite high PDA tumors (see below). 
Collectively, these findings suggest that immunotherapy has a role in PDA. 
3.2 
MISMATCH REPAIR PATHWAY AND SUSCEPTIBILITY TO 
IMMUNOTHERAPY 
Of particular interest is the observation that patients with mismatch repair-deficient 
(MMR-D) PDA respond to checkpoint inhibitors (Rizvi et al. 2015). MMR-D colorectal 
cancer tumors have 10 to 100 times as many somatic mutations compared to mismatch 
repair-proficient (MMR-P) colorectal tumors (Timmermann et al. 2010). In a phase 2 
study that included 10 patients with MMR-D colorectal cancer, four exhibited an 
immune- related objective response compared to none of the nine within the MMR-P 
cohort when treated with pembrolizumab monotherapy. At the time the study was 
published, median progression-free survival and OS was not reached within the 
MMR-D cohort, while it was 2.2 and 5.0 months, respectively, within the MMR-P 
cohort (Rizvi et al. 2015; Neoptolemos et al. 2017). Whole-exome sequences identified 
a mean of 1782 somatic mutations per tumor in patients in nine MMR-D colorectal 
cancer patients, compared with 73 mutations per tumor in patients with MMR-P. 
Membranous PD-L1 expression occurred only in tumors of MMR-D patients and was 
prominent on TILs and tumor-associated macrophages at the invasive fronts of the 
tumor (Lee et al. 2015). The leading hypothesis to the responsiveness of MMR-D 
colorectal cancer to PD-1 targeted therapy is the increased number of 
mutation-associated neoantigens. An additional preliminary report of 4 patients with 
PDA identified that 2 had partial responses and 2 had stable disease (Rizvi et al. 2015).  
However, PDA with MMR-P tumors constitute greater than 98% of cases for which 
immunotherapy is not currently efficacious. 
3.3 
STUDY RATIONALE  
Atezolizumab Arm 
Although early phase trials have not offered great success in the metastatic setting for 
patients with PDA, interim analysis of a multicenter, phase 1 trial with durvalumab 
presented at ESMO indicated a disease control rate of 21% (Ene-Obong et al. 2013). 
As mentioned previously, PD-L1 expression correlates with poor prognosis and 
decreased CD4+ and CD8+ T cell infiltration within the tumor. Targeting PD-L1 in the 
micrometastatic setting (resectable disease), when robust mature immunosuppressive

pathways may not have yet formed, may be the optimum time to investigate anti-PD-L1 
therapy. This arm of the study aims to test if atezolizumab is able to modulate CD8+ 
T-cell infiltration compared to historical matched controls. As a secondary endpoint 
we will also evaluate how clinical outcomes compare to matched historical controls.

Neoplastic, immune, and stromal cells within PDA reside in a highly dense desmoplastic 
environment composed of an extracellular matrix of which hyalouronidase (HA) is an 
abundant component. HA is a linear glycosaminoglycan and an integral component of not 
only PDA tumors, but has also been shown to accumulate in many solid tumors and is 
associated with a poor prognosis and increased immunosuppression (Provenzano et al. 
2012; Cheng et al. 2013). In a preclinical autochthonous mouse model of PDA, Sunil 
Hingorani s group demonstrated that the interstitial fluid pressures were unusually high 
within tumors that exhibited a high HA content. Furthermore, high HA tumors contained 
low vascularity, which compromised delivery of chemotherapeutic agents, such as 
gemcitabine. Mice treated with hyaluronidase resulted in decreased HA content and 
microvasculature re-expansion within tumors which led to a survival benefit 
(Provenzano et al. 2012). These preclinical studies led to early phase clinical studies in 
metastatic PDA where addition of PEGPH20 to gemcitabine and nab-paclitaxel (GA) in a 
randomized phase 2 study demonstrated a survival benefit in patients with HA-high 
tumors. The objective response rate for patients who were treated with a combination of 
PEGPH20 and GA compared to GA alone was 45% versus 31%, respectively, and the 
median overall survival was 11.5 versus 8.5 months, respectively (hazard ratio (HR), 
0.96; 95% CI, 0.57 to 1.61) (Hingorani et al. 2018). A large phase 3 randomized clinical 
trial in the high HA stage IV PDA population in the first line setting is ongoing. 
PDA likely invokes multiple immune evading mechanisms which result in its aggressive 
behavior; it is expected that multiple agents will likely be needed to develop effective 
therapies. One such rationale is the combination of PEGPH20 and immune checkpoint 
blockade to allow increased cytotoxic T-cell infiltration by increasing vascular 
permeability and decreasing interstitial pressure. In a breast cancer preclinical model, 
PEGPH20 resulted in an increase accumulation of CD8+ TIL by 176% (p=0.0025) and 
improved tumor growth inhibition by 38% relative to anti-PD-L1 alone (86% vs 62.4%, 
p=0.0024) (Clift et al. 2017). Other preclinical studies are also demonstrating increased 
CD8+ T-cell infiltration with addition of PEGPH20 and improved tumor control in 
combination with immune checkpoint blockade (Lee et al. 2017). These and other 
preclinical studies suggest that this combination is worth pursuing in patients with 
resectable PDA. The combination is hoped to increase CD8+ T-cell infiltration within the 
primary tumor for improved immune mediated cytotoxicity and decreased interstitial 
pressure to allow improved surgical resections. Hypothetically, the combination should 
also be effective in foci of micrometastasis, where the TME may not be as mature.

Atezolizumab is a humanized immunoglobulin (Ig) G1 monoclonal antibody which 
targets PD-L1 on tumor-infiltrating immune cells or tumor cells. The antibody blocks 
interaction of PD-L1 to PD-1 receptor and CD80 (B7.1), which are inhibitory receptors 
on immune cells, including T cells. This inhibition is thought to enhance tumor specific 
T-cell function through enhanced priming, expansion, and effector function (Okazaki 
and Honjo 2007). Hence, disrupting this pathway by atezolizumab has been effective in 
various tumor subtypes. Atezolizumab lacks Fc-effector function as it is engineered to be 
a non-glycosylated antibody, and hence does not function in antibody-dependent 
cell-mediated cytotoxicity or antibody mediated clearance of activated effector T cells.

albumin levels, tumor burden, renal impairment, mild hepatic impairment, level of PD-L1 
expression, or Eastern Cooperative Oncology Group (ECOG) status had no clinically 
relevant effect. Positive anti-drug antibody (ADA) status against atezolizumab led to 
approximately 13% reduction in overall exposure. The effect of hepatic impairment

 
If at any time the patient develops unacceptable toxicity, he/she will be removed 
from study. 
 
If at any time the patient is found to be ineligible for the protocol as designated in the 
section on Criteria for Patient/Patient Eligibility (i.e., a change in diagnosis), the 
patient will be removed from study. 
 
If the patient fails to comply with the defined treatment plan and follow-up 
evaluations, the patient will be removed from the study. 
 
If the patient withdraws consent for continued participation, he/she will be removed 
from study. 
 
The reasons a patient may discontinue or be withdrawn from the study include, but 
are not limited to, adverse event, clinically significant disease recurrence, patient 
request, investigator decision, protocol violation, patient noncompliance, and study 
termination by the Sponsor or institutional review board (IRB)/independent ethics 
committee (IEC). When a patient discontinues or is withdrawn, the investigator will 
notify the Sponsor and should perform the procedures indicated in the End of Study 
column in the Schedule of Events within 28 days after discontinuation of study drug 
and before initiation of any new anti-cancer therapy. Follow-up information will be 
obtained for patients who discontinue their participation in or are withdrawn from the 
study. 
 
Patients withdrawn from the study for reasons other than toxicity or clinically 
significant disease recurrence (e.g., protocol violation or noncompliance) will be 
replaced. Study drug administration may be discontinued for an adverse event or at 
the discretion of the investigator.

We believe that the combinations being tested, including atezolizumab combined with 
PEGPH20, compared to atezolizumab alone, will result in an increase in CD8+ T-cell 
infiltration within the tumor microenvironment. 
A detailed protocol of tissue processing is provided in the laboratory manual. Briefly, 
required endoscopic ultrasound-guided pre-treatment biopsy will be performed to obtain 
at least four additional tumor cores if deemed safe. Required on-treatment repeat biopsy 
to obtain at least four research tumor cores will be performed under direct visualization 
of the pancreas tumor by the operating surgeon at time of surgical resection within the 
operating room immediately preceding excision of the tumor if deemed safe.

7.1.1 
PDA Subtypes as Defined by Immune Cell Infiltrate and Gene 
Expression 
 
CD8+ T-Cell Infiltration and PDA Survival 
CD8+ TILs, which are known anti-tumor effector cells, are rarely found in the PDA 
tumor microenvironment (Vonderheide and Bayne 2013). This may in part be 
explained by the unique desmoplastic stroma, found adjacent to PDA tumor cells, 
which may act as a physical barrier to T-cell infiltration although this hypothesis has 
been challenged by a recently reported study (Ene-Obong et al. 2013; Carstens et al. 
2017). In addition, the PDA stroma is typically infiltrated with significant numbers of 
immunosuppressive leukocytes including tumor-associated macrophages, myeloid- 
derived suppressor cells (MDSC), and regulatory T cells (Hiraoka et al. 2006; Clark et 
al. 2007). Nevertheless, recent evidence has surfaced supporting a correlation 
between increased CD8+ lymphocyte infiltration and improved prognosis, suggesting 
CD8+ infiltration may serve as a good surrogate for response to therapy (Cheng et 
al. 2013; Deng et al. 2016). Human pancreas tumor probed for distinct markers using 
quantitative multiplex 
immunofluorescence (qmIF) 
which identifies specific 
immune subtypes is depicted 
in  
 
 
. Using qmIF, Carstens et al. 
demonstrated that high 
infiltration of CD8+ and CD4+ 
T-cells correlated with 
improved survival, whereas 
infiltration of regulatory T cells 
or other T cell subtypes was 
not. In addition, increased 
infiltration of intra-tumoral 
CD8+ T cells within a 20M radius of tumor cells also correlated with prolonged patient 
survival (Deng et al. 2016).

We hypothesize that PEGPH20 will change the regulatory context of PDA from an 
immunotherapy-resistant to an immunotherapy-sensitive phenotype. Fresh frozen 
tissue will be sectioned for laser capture microdissection of the neoplastic epithelial 
and stromal components for RNA extraction. 
PDA tumors are characterized by two main components: the epithelium, formed from 
aggregates of tumor cells, and the surrounding stroma. Moffitt et al. performed virtual 
microdissection on gene expression microarray data obtained from 145 PDA patients, 
and identified two distinct epithelial-specific subtypes. One subtype contained genes 
enriched for extracellular matrix (ECM) deposition and remodeling, which they termed 
basal-like , while the other was enriched in immune and interleukin pathways, which 
they termed classical . Distinct gene signatures represented by 25 distinct genes were 
able to distinguish these two phenotypes. The classical molecular subtype represented a 
patient population with an improved median OS compared to that of the basal-like 
subtype (Moffitt et al. 2015).

The Olive lab has performed LCM on over 200 human pancreatic tumors and RNA-seq 
to a depth of 30 million 100 base pair single-end reads. Their analyses showed clean 
separation of the two compartments and hierarchical clustering, using Neutral Matrix 
Factorization of the top 1000 variable genes of the stromal RNA-seq data, found two 
distinct clusters. One cluster was enriched for inflammatory genes while the other was 
enriched in both immune effector and immunosuppressive signatures; these groups 
were classified classical  and basal-like  subtypes, respectively [Kenneth Olive, 
submitted]. Furthermore, supervised clustering analysis of the RNA-seq data, using the 
same epithelial classifier signatures described by Moffitt et al., confirmed the prognostic 
value of PDA molecular subtypes in the CUMC cohort. As shown in (UURU5HIHUHQFH
VRXUFHQRWIRXQG, patients with the classical epithelial phenotype have significantly 
better prognoses as compared to basal-like phenotype [Kenneth Olive, submitted]. 
We hypothesize that the addition of PEGPH20 to atezolizumab, including other 
agents to be tested, compared to atezolizumab alone will result in gene regulation to 
enrich for the immune and interleukin pathways, which reflect classical/immune 
subtype compared to the basal-like/ECM subtype. In order to test this hypothesis, the 
epithelium compartment will be isolated using LCM from each resected tumor specimen 
on which RNA-seq analysis will be performed. Using epithelial classifiers, as described 
above, samples will be compared from distinct treatment groups to determine if certain 
treatments are able to alter the PDA epithelial gene expression from a basal/ECM-like  
to a classical/immune  subtype which may confer a prognostic advantage. If a 
treatment(s) leads to enrichment for classical/immune subtype and improved 
outcomes, the regulated pathways that associate with improved disease free survival 
will need to be validated in a larger sample and those pathways further exploited to 
convert the tumor into one that is more susceptible to immunotherapy. These studies 
will complement the multiplex immunofluorescence (IF) studies described above and 
will hopefully identify key regulatory pathways affected by distinct therapies.

Atezolizumab will be administered at a fixed dose of 840 mg IV every 2 weeks (Q2W) 
(i.e. on Days 4 and 18 prior to surgery and on Days 1 and 15 of each 28 day cycle after 
surgery). The average concentration following the 840 mg Q2W dosage is expected to 
be equivalent to that of 1200 mg every 3 weeks (Q3W), the approved dosage for 
atezolizumab (Tecentriq£ U.S. Package Insert). Anti-tumor activity has been observed 
across doses ranging from 1 mg/kg to 20 mg/kg Q3W. In Study PCD4989g, the 
maximum tolerated dose of atezolizumab was not reached and no dose-limiting toxicities 
were observed at any dose. The fixed dose of 1200 mg Q3W (equivalent to an average 
body weight-based dose of 15 mg/kg Q3W) was selected on the basis of both nonclinical 
studies and available clinical pharmacokinetic, efficacy, and safety data (refer to the 
Atezolizumab Investigator’s Brochure for details) (Deng et al. 2016). 
The atezolizumab Drug Product will be supplied by the Sponsor as a sterile liquid in a 
single-use, 20-mL glass vial. The vial contains approximately 20 mL (1200 mg) of 
atezolizumab solution. 
For information on the formulation and handling of atezolizumab, drug preparation, 
storage, and administration see the pharmacy manual and the Atezolizumab 
Investigator’s Brochure. Guidelines for medical management of infusion-related 
reactions (IRRs) for atezolizumab are provided in Appendix 2. 
Administration of atezolizumab will be performed in a monitored setting where there is 
immediate access to trained personnel and adequate equipment and medicine to 
manage potentially serious reactions. Standard anaphylaxis precautions should be taken 
when administering atezolizumab. Treatment for anaphylaxis will be administered per 
the instructions outlined below

following procedures should be performed: 
1. 
Stop the study treatment infusion. 
2. 
Apply a tourniquet proximal to the injection site to slow systemic absorption of study 
treatment. Do not obstruct arterial flow in the limb. 
3. 
Maintain an adequate airway. 
4. 
Administer antihistamines, epinephrine, or other medications as required by patient 
status and directed by the physician in charge. 
5. 
Continue to observe the patient and document observations. 
 
No dose modification for atezolizumab is allowed. Guidelines for treatment interruption 
or discontinuation because of toxicities are provided below and within Appendix 2. 
Atezolizumab Treatment Interruption for Toxicities 
Atezolizumab treatment may be temporarily suspended in patients experiencing toxicity 
considered to be related to study treatment. If corticosteroids are initiated for treatment 
of the toxicity, they must be tapered over ≥1 month to ≤10 mg/day oral prednisone or 
equivalent before atezolizumab can be resumed. Appropriate steroids supplementation 
should be provided if required prior to surgery in consultation with an endocrinologist and 
a pulmonologist in cases of pneumonitis. If atezolizumab is withheld for >12 weeks, the 
patient will be discontinued from atezolizumab. However, atezolizumab may be withheld 
for > 12  weeks to allow for patients to taper off corticosteroids prior to resuming 
treatment. Atezolizumab can be resumed after being withheld for > 12 weeks if the PI 
agrees that the patient is likely to derive clinical benefit. Atezolizumab treatment may be 
suspended for reasons other than toxicity with PI approval.

PEGPH20 drug product supplied at a concentration of 0.30 mg/mL and will be supplied 
in a single-use vial that contains 1.0 mL. liquid formulation and should be stored at 2 C 
to 8 C before use. Stability testing of this PEGPH20 drug product was initiated and 
following general International Conference on Harmonisation (ICH) guidelines at 5 C – 
3 C, and concurrent stability evaluation is ongoing. For additional details regarding 
formulation and handling of PEGPH20, please refer to pharmacy manual and PEGPH20 
Investigator s Brochure. 
PEGPH20 will be administered by IV infusion at a dose of 3Pg/kg on Days 1 and 4 every 
week for 3 weeks prior to surgery and on Days 1, 8, and 15 every 28 days for 2 cycles 
after surgery. PEGPH20 will be administered 2-3 hours before the atezolizumab 
infusion. 
PEGPH20 should be infused over 10í12 minutes, equivalent to approximately 
1 mL/minute. 
Piroxicam (20mg) will be administered 1-2 hours prior to PEGPH20 administration to 
minimize severe musculoskeletal events (MSE). 
Prophylactic use of a proton-pump inhibitor (e.g., 20 mg omeprazole daily or over-the 
counter equivalent) is mandated for all patients while receiving PEGPH20. 
Enoxaparin will be administered daily to all patients to minimize the risk of 
thromboembolic events (TE), a known complication of patients with pancreas 
adenocarcinoma and a known adverse event in PDA patients who receive PEGPH20. 
Enoxaparin will be administered by subcutaneous injection at a dose of 1 mg/kg/day 
rounding of dose may be done per institution policy and when using prefilled syringes. 
The dosage of enoxaparin will be based on the subject s screening weight and should be 
modified if the subject s weight changes by 10%. On days of dosing of PEGPH20, 
enoxaparin will be administered prior to infusion of PEGPH20. All efforts should be made 
to administer the calculated 1 mg/kg dose (– 10%). If prefilled syringes are used, the 
treating physician may use medical judgment regarding the appropriate prefilled syringe. 
However, if the rounded dose varies from the expected weight-based dose by 20% or 
more, the PI should be consulted. Refer to Table 3 for examples of rounding based on 
the expected enoxaparin dose. Enoxaparin should be held if the platelet count is 
<50,000 per mm3 and should be resumed once the platelet count is greater than 50,000 
per mm3. The enoxaparin dose should be reduced to 0.5mg/kg for Grade 2 
thrombocytopenia (platelet count 50,000  75,000 platelet per mm3) until an increase in 
platelets > 75,000 platelet per mm3, at which time the dose should be increased to

1mg/kg. Should a subject experience a TE event while on study, the dose of enoxaparin 
will be increased to a therapeutic dose based on standard clinical practice.  
In situations when enoxaparin is held, administration of PEGPG20 should also be held 
during that period. Subjects who permanently discontinue enoxaparin therapy for any 
reason will also permanently discontinue PEGPH20. Likewise, enoxaparin treatment 
should be discontinued unless clinically indicated when the subject discontinues 
PEGPH20.

PEGPH20 treatment interruption for Toxicities 
PEGPH20 treatment may be interrupted for reasons other than toxicity with PI approval. 
The acceptable length of treatment interruption will be determined by the PI.

Atezolizumab in Combination with PEGPH20 Administration 
Patients in the atezolizumab + PEGPH20 arm will receive treatment as outlined in 
Table 4 until unacceptable toxicity or loss of clinical benefit as determined by the 
investigator after an integrated assessment of radiographic and biochemical data, local 
biopsy results (if available), and clinical status (e.g., symptomatic deterioration such as 
pain secondary to disease). Treatment must be initiated no later than 5 days after 
randomization.

Toxicities 
If atezolizumab is discontinued, PEGPH20 should also be discontinued. If PEGPH20 is 
discontinued, atezolizumab can be continued if the patient is likely to derive clinical 
benefit, as determined by the investigator in consultation with the PI. Refer to 
Appendix 3 for guidance. 
The dose of PEGPH20 can be reduced to 1.6 g/kg for management of drug-related 
toxicities. If further dose reduction is indicated, the patient must discontinue PEGPH20 
but may continue treatment with atezolizumab if approved by the PI. After dose 
reduction, the dose of PEGPH20 may not be escalated. 
Atezolizumab treatment may be temporarily suspended in patients experiencing toxicity 
considered to be related to study treatment. If corticosteroids are initiated for treatment 
of the toxicity, they must be tapered over ≥ 1 month to ≤10 mg/day oral prednisone or 
equivalent before atezolizumab can be resumed. If atezolizumab is withheld for > 12

Adverse events of special interest are required to be reported to the PI immediately (i.e. 
no more than 24 hours after learning of the event). 
Adverse events of special interest for the atezolizumab + PEGPH20 arm are as follows: 
x 
Cases of potential drug-induced liver injury that include an elevated ALT or AST in 
combination with either elevated bilirubin or clinical jaundice. The finding of an 
elevated ALT or AST (> 3  baseline value) in combination with either an elevated 
total bilirubin (> 2  ULN) or clinical jaundice in the absence of cholestasis or other 
causes of hyperbilirubinemia is considered to be an indicator of severe liver injury 
(as defined by Hy’s Law). Therefore, investigators must report as an adverse event 
the occurrence of either of the following: 
±
Treatment-emergent ALT or AST > 3  baseline value in combination with total 
bilirubin > 2  ULN (of which 35% is direct bilirubin)  
±
Treatment-emergent ALT or AST > 3  baseline value in combination with 
clinical jaundice. The most appropriate diagnosis or (if a diagnosis cannot be 
established) the abnormal laboratory values should be recorded on the Adverse 
Event eCRF and reported to the Sponsor immediately (i.e., no more than 24 
hours after learning of the event), either as a serious adverse event or an 
adverse event of special interest (AESI)  

Suspected transmission of an infectious agent by the study treatment, as defined 
below: Any organism, virus, or infectious particle (e.g., prion protein transmitting 
transmissible spongiform encephalopathy), pathogenic or non-pathogenic, is

Surgical resection of the pancreas adenocarcinoma with negative margins represents 
the primary modality through which cure is achieved in patients with pancreatic 
cancer. As surgical techniques and expertise have evolved, increased long-term 
survival rates have been reported, however, it was not until 2007, when the results 
of the phase 3 CONKO-001 trial were published, that the role of adjuvant 
chemotherapy became firmly established (Oettle et al. 2007). In this randomized 
controlled phase 3 trial, patients were stratified 1:1 to chemotherapy, in which 
patients were to receive 6 cycles of gemcitabine given on Days 1, 8, and 15 every 4 
weeks (n = 179), or observation (n = 175) following surgery. The trial demonstrated a 
median disease-free survival of 13.4 months in those receiving gemcitabine compared 
with 6.9 months in those who received no adjuvant therapy (95% confidence interval 
[CI], 6.1-7.8; P<0.001, log-rank). Long term follow-up of patients in this study 
demonstrated over a 10% difference in overall survival at 5 years (20.7% with 
gemcitabine versus 10.4% with observation) (Oettle et al. 2013). In 2010, gemcitabine 
was compared head-to-head with fluorouracil plus folinic acid in the randomized

controlled phase 3 European Study Group for Pancreatic Cancer (ESPAC)-3 trial 
(Neoptolemos et al. 2010). Patients with resectable pancreatic cancer were treated 
with either gemcitabine (n = 537) or fluorouracil plus folinic acid (n = 551) after surgery. 
The median overall survival was 23.6 months in those treated with gemcitabine and 23.0 
months in those treated with fluorouracil plus folinic acid, however these results did not 
meet statistical significance (P = .39; HR, 0.94 [95% CI, 0.81-1.08]). Toxicity profiles 
significantly favored the use of gemcitabine compared to fluorouracil plus folinic acid. 
Regardless of the regimen used, these trials show a clear benefit to receiving adjuvant 
chemotherapy, and this practice has since become standard of care. 
This approach, surgery followed by adjuvant chemotherapy, is also supported by 
several large systematic reviews. In one large meta-analysis, 951 pancreatic cancer 
patients were pooled from multiple randomized control trials in which patients were 
either treated with adjuvant chemotherapy or observed, and the addition of adjuvant 
chemotherapy prolonged the median survival time by 3 months and increased 5-year 
survival rates by 3.1% (Boeck et al. 2007). Another large meta-analysis of 875 patients 
showed reduction in the risk of death with chemotherapy by approximately 25% 
versus surgery alone. This study also demonstrated a doubling of the 5-year survival 
rates with adjuvant chemotherapy compared to observation (Stocken et al. 2005). 
The phase 3 ESPAC-4 trial compared gemcitabine and capecitabine in the 
adjuvant setting compared to gemcitabine alone. The investigators reported an 
additional 2.5 month survival benefit with the addition of capecitabine to 
gemcitabine (28.0 months with gemcitabine plus capecitabine vs 25.5 months with 
gemcitabine alone, HR, 0.82 [95% CI, 0.68 0.98], p=0.032) (Neoptolemos et al. 
2017). This combination is now being adopted given the overall survival benefit. 
However, within the United States, the doses used within the study are intolerable and 
require frequent dose and/or schedule modifications. It is likely that the frequent dose 
adjustments impact the efficacy of the combination to a degree which is currently 
unknown. 
PRODIGE 24, a large randomized phase 3 study compared mFOLFIRINOX to 
gemcitabine monotherapy in the adjuvant setting and demonstrated a median overall 
survival benefit of 54.4 months compared to 35.0 months, respectively. The median 
disease free survival was 21.6 months in the mFOLFIRINOX arm compared to 12.8 
months in the gemcitabine monotherapy arm (Andre et al. 2018; Conroy et al. 2018). 
The reported 18-month overall survival (OS) is 67% with adjuvant gemcitabine in 
combination with capecitabine which is similar to the 63% reported when gemcitabine 
and oxaliplatin were tested in the neoadjuvant setting (O’Reilly et al. 2016). Although 
mFOLFIRINOX yielded impressive results, patients enrolled onto the study had a better 
performance status to withstand mFOLFIRINOX. Although SWOG S1313 indicated a

detrimental effect of adding pegylated recombinant human hyalouronidase (PEGPH20) 
to FOLFIRINOX compared to FOLFIRINOX alone, the current study is testing activity of 
PEGPH20 in combination with atezolizumab concurrently with subsequent treatment 
with mFOLFIRINOX which is distinct from concurrent therapy with PEGPH20 and 
mFOLFIRINOX as tested in SWOG S1313. Hence, we do not anticipate added risk to 
subjects who will be randomized to the atezolizumab and PEGPH20 cohort.

phase 2-3 randomized trial in patients with ECOG 0 or 1, FOLFIRINOX (Fluorouracil 400 
mg/m2 as a bolus followed by 2400 mg/m2 given as a 46-hour continuous infusion, 
irinotecan 180 mg/m2, and oxaliplatin as 85 mg/m2, every 2 weeks) resulted in an 11.1 
month overall survival compared to 6.8 months with gemcitabine  a 4.3 month survival 
benefit over gemcitabine alone (HR 0.57; 95% CI, 0.37 to 0.59; P<0.001) (Conroy T, et 
al. 2011). Median PFS and objective response rate (RR) both favored FOLFIRINOX 
compared to gemcitabine alone; 6.4 months and 31.6% compared to 3.3 months and 
9.4% in the group, respectively (P<0.001). One-year overall survival was 48.4% in the 
FOLFIRINOX arm versus 20.6% in the gemcitabine arm (Conroy T, et al. 2011). 
Although FOLFIRINOX is clearly superior to gemcitabine monotherapy, treatment is 
reserved for patients with excellent performance status due to its adverse event profile, 
which includes fatigue, bone marrow suppression with 45.7% grade 3 or 4 neutropenia, 
12.7% diarrhea, and 9.0% sensory neuropathy. A follow-up of the PRODIGE 4/ACCORD

11 study indicated that efficacy was only mildly impacted in the 81% of the 242 patients 
who required dose reduction (mOS 10.9m versus 11.1m) (Metges JP, et al. 2014).  
Due to poor tolerability of FOLFIRINOX in a significant proportion of patients, regimens 
with reduced doses of irinotecan and bolus fluorouracil, or omission of bolus fluorouracil, 
and addition of pegfilgastrim on day 3 or 4, commonly referred to as mFOLFIRINOX  
are widely used. mFOLFIRINOX resulted in a response rate of 30%, mPFS of 8.5 
months, and mOS of 9.0 months in the 36 patients tested in the metastatic setting 
(Mahaseth H, et al. 2013). A prospective single arm phase 2 study tested the regimen 
with 25% dose reduction of bolus fluorouracil and irinotecan and found the RR, mPFS, 
and mOS to be 35.1%, 6.1 months, and 10.2 months respectively, which was 
comparable to that reported in the original PRODIGE 4/ACCORD 11 trial (Stein SM, et 
al. 2016). With the caveat of comparing distinct trials and limited number of patients, 
mFOLFIRINOX although better tolerated, may not be equivalent to full dose 
FOLFIRINOX when compared for efficacy, and it appears that the dose reduced forms 
have a shorter mOS. For patients who do not have a robust performance status or are 
intolerant to gem/QDE-p, there may not be a choice but to use the dose-reduced regimen. 
Prophylactic administration of pegylated filgastrim in the absence of severe leukocytosis 
and pretreatment with palonosetron, aprepitant and dexamethasone likely contribute to a 
decrease in adverse events (Stein SM, et al. 2016). Pretreatment with atropine also 
appears to help with the cholinergic symptoms associated with Irinotecan. Other 
FOLFIRINOX modifications are described elsewhere (Marsh R, et al. 2015).

Cautionary Therapy 
Systemic corticosteroids and tumor necrosis factor  (TNF-) inhibitors may attenuate 
potential beneficial immunologic effects of treatment with atezolizumab. Therefore, in 
situations in which systemic corticosteroids or TNF- inhibitors would be routinely 
administered, alternatives, including antihistamines, should be considered. If the 
alternatives are not feasible, patient will not meet eligibility criteria.

x 
Ketorolac for severe pain Ketorolac may be given for severe pain as recommended 
in the prescribing information. Ketorolac should not be administered on the same 
day as piroxicam or other nonsteroidal anti-inflammatory drugs (NSAIDs) because 
of the cumulative risk of inducing serious NSAID-related side effects. 
x 
Prescription medications such as narcotics, muscle relaxants, NSAIDs and other 
analgesics (with the exception of corticosteroids), over-the-counter drugs, and 
physical therapy for treatment of MSEs, at the investigator’s discretion NSAIDs 
should not be administered on the same day as piroxicam.  
x 
Intravenous heparin for acute treatment of TE events. Only PEGPH20 must be 
withheld while the patient is receiving intravenous heparin.  
x 
Palliative radiotherapy (e.g., treatment of known bony metastases or symptomatic 
relief of pain) as outlined below:  
Palliative radiotherapy is permitted, provided it does not interfere with the 
assessment of tumor target lesions (e.g., the lesion to be irradiated must not be 
the only site of measurable disease). Treatment with atezolizumab and 
PEGPH20 may be continued during palliative radiotherapy.  
x 
Radiotherapy to the brain as outlined below:  
Patients whose extracranial tumor burden is stable or responding to study 
treatment and who are subsequently found to have three or fewer brain 
metastases may receive radiotherapy to the brain (either stereotactic 
radiosurgery or whole-brain radiation therapy) provided that all of the following 
criteria are met:  
±
The patient has no evidence of progression or hemorrhage after 
completion of central nervous system (CNS)-directed therapy.  
±
The patient has no ongoing requirement for corticosteroids as therapy for 
CNS disease. Patients who require corticosteroid therapy for more than 
7 days after completion of radiotherapy must be discontinued from study 
treatment.  
±
Anti-convulsant therapy, if required, is administered at a stable dose. 
 
Premedication with antihistamines, antipyretics, and/or analgesics may be administered 
for the second and subsequent atezolizumab infusions only, at the discretion of the 
investigator. 
Hematopoietic growth factors are not to be administered prophylactically prior to the first 
doses of adjuvant chemotherapy. However, at the discretion of the investigator, 
hematopoietic growth factors may be administered prophylactically per standard local 
practice before the second and subsequent doses of study treatment.

In general, investigators should manage a patient s care with supportive therapies as 
clinically indicated, per local standard practice. Patients who experience infusion-
associated symptoms may be treated symptomatically with acetaminophen, ibuprofen, 
diphenhydramine, and/or H2-receptor antagonists (e.g., famotidine, cimetidine), or 
equivalent medications per local standard practice. Serious infusion-associated events 
manifested by dyspnea, hypotension, wheezing, bronchospasm, tachycardia, reduced 
oxygen saturation, or respiratory distress should be managed with supportive therapies 
as clinically indicated (e.g., supplemental oxygen and E2- adrenergic agonists; see 
Appendix 2).

Use of the following concomitant therapies is prohibited as described below:  
x 
Concomitant therapy intended for the treatment of cancer (including, but not limited 
to, chemotherapy, immunotherapy, radiotherapy, and herbal therapy), whether 
health authorityíapproved or experimental, is prohibited, and during study treatment 
until disease progression is documented and the patient has discontinued study 
treatment, with the exception of palliative radiotherapy and radiotherapy to the brain.  
x 
Investigational therapy (other than protocol-mandated study treatment) is prohibited 
within 28 days prior to initiation of study treatment and during study treatment.  
x 
Live, attenuated vaccines (e.g., FluMist ) are prohibited within 4 weeks prior to 
initiation of study treatment, during treatment with atezolizumab, and for 5 months 
after the last dose of atezolizumab.  
x 
Systemic immunostimulatory agents (including, but not limited to, interferons and 
interleukin-2) are prohibited within 4 weeks or five half-lives of the drug, whichever is 
longer, prior to initiation of study treatment and during study treatment because 
these agents could potentially increase the risk for autoimmune conditions when 
given in combination with atezolizumab. 
x 
Systemic immunosuppressive medications (including, but not limited to, 
cyclophosphamide, azathioprine, methotrexate, and thalidomide) are prohibited 
during study treatment because these agents could potentially alter the efficacy and 
safety of atezolizumab.  
x 
Chronic use of intravenous heparin is prohibited during treatment with PEGPH20. 
However, intravenous heparin may be given for acute treatment of TE events.  
x 
Megestrol acetate is prohibited within 10 days prior to initiation of PEGPH20 and 
during treatment with PEGPH20. 
The above lists of cautionary medications are not necessarily comprehensive. The 
investigator should consult the prescribing information when determining whether a 
concomitant medication can be safety administered with study treatment. In addition, 
the investigator should contact the PI if questions arise regarding medications not listed 
above.

Please refer to the must updated PEGPH20 IB. Identified risks for PEGPH20 include 
MSEs such as myalgia and arthralgia, infusion-related reactions, and TE events see 
below). Refer to the PEGPH20 Investigator’s Brochure for a detailed description of all 
anticipated risks for PEGPH20.

The majority of treatment-related adverse events have been MSEs. The severity of 
the MSEs appeared to be influenced by the dose and dosing frequency of 
PEGPH20. In general, symptoms tended to be more severe with higher doses of 
PEGPH20 and a more frequent dosing schedule. At the highest doses tested in 
humans (50 g/kg), Grade 3 or 4 MSEs occurred approximately 4í10 hours after 
the first dose. Reported MSEs include, but are not limited to, muscle spasms, 
arthralgia, myalgia, muscular weakness, pain in extremity, back pain, bone pain, 
musculoskeletal pain, joint swelling, joint stiffness, limb discomfort, musculoskeletal 
stiffness, myositis, and neck pain. Treatment with dexamethasone has been used to 
attenuate the severity of MSEs, improving the tolerability of higher PEGPH20 dose 
and dosing frequency combinations. However, given that corticosteroid treatment 
(i.e., dexamethasone) may potentially interfere with the efficacy of atezolizumab, 
treatment with NSAIDs is being used instead of corticosteroids in this study. 
Piroxicam and ketorolac have been investigated in an animal model of MSEs and 
may be helpful in decreasing the severity of MSEs in patients (Halozyme internal 
unpublished report). In this study, piroxicam will therefore be administered as 
premedication to decrease the severity of MSEs. Ketorolac may be given for severe 
pain per the prescribing information. Ketorolac and other NSAIDs should not be 
administered on the same day as piroxicam.

TE events and, more frequently, venous TE events, are reported to occur with 
higher frequency in patients with pancreatic cancer. The PEGPH20 Investigator’s 
Brochure indicates that patients with a history of cerebrovascular accident, deep 
vein thrombosis, or pulmonary embolism, or a history or evidence of carotid artery 
disease are not eligible to participate in PEGPH20 clinical studies. Patients will be 
treated prophylactically with subcutaneous enoxaparin to reduce the risk of TE 
events. It is well documented that the use of megestrol acetate causes thrombosis; 
therefore, concomitant use of megestrol acetate is prohibited during treatment with 
PEGPH20.

subsequent imaging confirms tumor growth, recurrence will be back dated to the 
prior scan. If patient agrees to treatment beyond recurrence, the patient will be 
required to sign a Treatment Beyond Recurrence  informed consent form. Biopsy 
of the lesion demonstrating recurrence will be required to determine histologic 
disease recurrence, unless it is unsafe to do so. In case where a biopsy is not 
possible, data from rise in tumor markers and/or enlarging size of lesion on repeat 
imaging in 6 weeks (+/- 2 weeks) will be used to adjudicate recurrence by the

The reasons a patient may discontinue or be withdrawn from the study include, but are 
not limited to, adverse event, clinically significant disease recurrence, patient request, 
investigator decision, deemed surgically inoperable for any reason, major protocol 
violation such that patient is deemed not suitable to continue therapy, patient 
noncompliance, and study termination by the Sponsor or IRB/ IEC. When a patient 
discontinues or is withdrawn, the investigator will notify the Sponsor and should 
perform the procedures indicated in the End of Study column in the Schedule of 
Events within 28 days after discontinuation of study drug and before initiation of any 
new anti-cancer therapy. Follow-up information will be obtained for patients who 
discontinue their participation in or are withdrawn from the study. 
Patients withdrawn from the study for reasons other than toxicity or clinically significant 
disease recurrence (e.g., protocol violation or noncompliance) may be replaced at the 
discretion of the PI and the investigator. Study drug administration may be

Dose Modifications for Management of Atezolizumab-Specific Adverse 
Events 
There will be no dose modifications for atezolizumab in this study. 
Atezolizumab treatment may be temporarily suspended in patients experiencing toxicity 
considered to be related to study treatment. If corticosteroids are initiated for treatment 
of the toxicity, they must be tapered over 1 month to  10 mg/day oral prednisone or 
equivalent before atezolizumab can be resumed. If atezolizumab is withheld for  12 
weeks, the patient will be discontinued from atezolizumab. However, atezolizumab may 
be withheld for  12 weeks to allow for patients to taper off corticosteroids prior to 
resuming treatment. Atezolizumab can be resumed after being withheld for  12 weeks if 
the PI agrees that the patient is likely to derive clinical benefit.  
Toxicities associated or possibly associated with atezolizumab treatment should be 
managed according to standard medical practice. Additional tests, such as autoimmune 
serology or biopsies, should be used to evaluate for a possible immunogenic etiology. 
Although most immune-related adverse events observed with immunomodulatory 
agents have been mild and self-limiting, such events should be recognized early and 
treated promptly to avoid potential major complications. Discontinuation of 
atezolizumab may not have an immediate therapeutic effect, and in severe cases, 
immune-related toxicities may require acute management with topical corticosteroids, 
systemic corticosteroids, or other immunosuppressive agents. 
The investigator should consider the benefit-risk balance a given patient may be 
experiencing prior to further administration of atezolizumab. In patients who have met 
the criteria for permanent discontinuation, resumption of atezolizumab may be 
considered if the patient is deriving benefit and has fully recovered from the immune-
related event. Patients can be re-challenged with atezolizumab only after approval

development program are consistent with the known mechanism of action of 
atezolizumab and the underlying disease. Overall, treatment with atezolizumab is well 
tolerated with a manageable adverse event profile. Currently, no maximum tolerated 
dose, no dose-limiting toxicities (DLTs), and no clear dose-related trends in the 
incidence of adverse events (AEs) have been determined. Among 3075 patients treated 
with single-agent atezolizumab for whom pooled safety data are available, the most 
commonly reported AEs ( 10%) include fatigue, decreased appetite, cough, nausea, 
dyspnea, constipation, diarrhea, pyrexia, vomiting, arthralgia, back pain, asthenia, 
anemia, pruritus, rash, headache, and peripheral edema.

The AEs observed with atezolizumab in combination with chemotherapy and/or targeted 
therapies are consistent with the known risks of the individual study treatment. Systemic 
immune activation, characterized by an excessive immune response, is a potential risk 
associated with atezolizumab when used in combination with another 
immunomodulating compound. Atezolizumab-related AEs were comparable between 
patients who received atezolizumab monotherapy and those who were treated with 
atezolizumab in combination with targeted therapy and/or chemotherapy. There are no 
atezolizumab-related AEs that are exacerbated when used in combination with other 
agents. 
Immune-related AEs are consistent with the role of the PD-L1/PD-1 pathway in 
regulating peripheral tolerance. Given the mechanism of action of atezolizumab, events 
associated with inflammation and/or immune-related AEs are closely monitored during 
the atezolizumab clinical program. Immune-related AEs associated with atezolizumab 
include pneumonitis, hepatitis, colitis, pancreatitis, diabetes mellitus, hypothyroidism, 
hyperthyroidism, adrenal insufficiency, hypophysitis, Guillain-Barr  syndrome, 
myasthenic syndrome/myasthenia gravis, meningoencephalitis, myocarditis and 
nephritis.   
Study GP28363 is evaluating combination cobimetinib and atezolizumab in patients with 
locally advanced or metastatic solid tumors. As of 4 September 2017, there were 
150 safety-evaluable patients with tumor types including colorectal cancer, metastatic 
melanoma, and NSCLC who were on different treatment regimens of 
atezolizumab  cobimetinib. 
Of the 150 safety-evaluable patients, 148 (98.7%) experienced an adverse event. The 
most frequently observed AEs (t 30%) were diarrhea (70.7%), fatigue (56.7%), rash 
(48%), vomiting (43.3%), nausea (36.7%), constipation (30%) and abdominal pain 
(22.7%). Adverse events assessed as related to atezolizumab were reported in 
117patients (78.0%). The most common such AEs (t 10%) were fatigue (31.3%), 
diarrhea (28.0%), pruritus (14.0%), rash (13.3%), and nausea (12.7%), vomiting 
(10.0%), pyrexia (10.0%)  
These findings are consistent with the known adverse event profiles for atezolizumab 
and cobimetinib and did not represent additive toxicity. 
Grade 34 AEs were observed in 99 (66.0%) of the patients, and the most common 
( t 2.7% or  t 4 patients) included fatigue (10.7%), anemia (10.0%), diarrhea (8.7%%), 
abdominal pain and blood creatinine phosphokinase increased (5.3% each), rash 
(4.7%), dyspnea, aspartate aminotransferase increased amylase increased and 
hypertension (4% each), and ascites, vomiting, peripheral edema, pleural effusion,

pulmonary embolism, blood bilirubin increased, lipase increased, neutrophil count 
decreased, hyponatraemia, and hypophosphatemia (2.7% each Most of the Grade 34 
AEs considered related to atezolizumab were single reports except for fatigue (3.3%), 
rash (2.7%), diarrhea (2%), amylase increase (2.7%), lipase increased and anaemia 
(2%), dermatitis acneiform, nausea, vomiting, dyspnea, aspartate aminotransferase 
increase and neutrophil count decrease (1.3% each).  
Six patients (4%) were reported to have had Grade 5 AEs. The following events led to 
death in 6 patients (4.0%): pneumonia, large intestine perforation, small intestinal 
obstruction, sepsis, road traffic accident, and respiratory failure. The event of sepsis was 
the only Grade 5 event considered related to atezolizumab. In this case, the patient had 
a medical history of infectious disease (right temporal lobe abscess). 
Sixty-nine safety-evaluable patients (46%) had a serious adverse event, most of which 
were single reports. The exceptions were pneumonia (6%), pyrexia and dyspnea (4% 
each), abdominal pain (3.3%), vomiting and sepsis (2.7%), fatigue, pulmonary embolism 
(2% each), and bacteremia, cellulitis, lung infection, ascites, intestinal obstruction, 
nausea, peripheral edema, pain, pleural effusion, pneumonitis, dehydration, and fall 
(1.3% each).   
Twenty-three safety-evaluable patients (15.3%) experienced an adverse event leading to 
discontinuation from atezolizumab. 
Reproductive and developmental toxicity studies with atezolizumab have not been 
conducted. The PD-L1/PD-1 signaling pathway is well established as essential in 
maternal/fetal tolerance and embryo-fetal survival during gestation (Guleria et al. 2005; 
Habicht et al. 2007; D’Addio et al. 2011). Administration of atezolizumab is expected to 
have an adverse effect on pregnancy via modulation of maternal/fetal tolerance, and 
poses a risk to the human fetus, including embryo-lethality via an increased risk of 
immune-mediated rejection.  
Other possible consequences of inhibiting the PD1/PD-L1 pathway may be the 
modulation of the host immune response to acute infection, which may result in 
dysregulated immune defenses and is currently a theoretical risk.

The overall safety analysis from HALO-109-202 study in patients with stage IV PDA who 
were treated with gemcitabine, nab-paclitaxel, and PEGPH20 in a phase 2 study 
confirmed musckulosekeletal events (MSEs; primarily grade 1 or 2 severity), 
thromboembolic events, and infusion-related reactions. Additionally, adverse. Trials 
combining immune check point blockade and PEGPH20 are ongoing with limited data 
available. 
Musculoskeletal events are an important identified risk due to their high frequency and 
the need to premedicate (with dexamethasone or NSAIDs as specified in the study 
protocols) to ameliorate their intensity. These events include but are not limited to 
Medical Dictionary for Regulatory Activities (MedDRA) preferred terms (PTs) such as 
muscle spasms, arthralgia, myalgia, muscular weakness, pain in extremity, back pain, 
bone pain, musculoskeletal pain, joint swelling, joint stiffness, limb discomfort, 
musculoskeletal stiffness, myositis, and neck pain. While the incidence across the 
clinical studies has been ≥75%, the events were mostly Grade 1/2 in severity, 
nonserious, and infrequently led to study treatment discontinuation. Musculoskeletal 
events continue to be observed very commonly in PEGPH20-treated patients. These 
events are managed by the administration of dexamethasone in ongoing studies, with 
the exception of the administration of piroxicam in studies with immunotherapies (as 
administered in HALO-107-101) due to the potential effect of steroids on efficacy. The 
dexamethasone and piroxicam prophylaxis appears to attenuate the severity of these 
events.  
Thromboembolic events (TEs) and their sequelae have been observed in clinical studies 
evaluating PEGPH20 combination therapies in patients with pancreatic cancer, NSCLC, 
and gastric cancer. It is widely accepted that PDA and gastric cancer are tumor types 
with a high TE event background rate. The observed events were mainly of venous 
origin and included PTs such as pulmonary embolism, thrombosis, embolism, 
mesenteric vein thrombosis, DVT, jugular vein thrombosis, and venous thrombosis. 
Arterial events have also been observed but less frequently than venous events and 
include PTs such as cerebral ischemia, cerebrovascular accident, splenic infarction, 
basal ganglia infarction, and myocardial infarction. Due to the risks of increased TE, all 
patients treated with PEGPH20 will also receive anticoagulation. 
Infusion-related reactions remain an identified risk of PEGPH20 although their overall 
incidence remains low (<5%). This risk was initially identified in Study HALO-109-201 
when PEGPH20 was initially administered either by IV push or over 4-5 minutes. Current 
protocol instructions require that PEGPH20 be administered by a slow IV infusion over 
10 minutes. This risk is being mitigated by administering PEGPH20 over 10 minutes as 
well as excluding patients with a known allergy to hyaluronidase.

Is associated with a serious adverse event 
x 
Is associated with clinical signs or symptoms 
x 
Leads to additional treatment or to further diagnostic tests

Important medical events are those that may not be immediately life threatening, but 
are clearly of major clinical significance. They may jeopardize the patient, and 
may require intervention to prevent one of the other serious outcomes noted 
above. For example, drug overdose or abuse, a seizure that did not result in in-
patient hospitalization or intensive treatment of bronchospasm in an emergency 
department would typically be considered serious. 
 
All adverse events that do not meet any of the criteria for serious events should be 
regarded as non-serious adverse events.

Unanticipated Problem: 
An unanticipated problem (UP) is any incident, experience or outcome involving risks 
to patients or others in any human patient/patient research that meets all of the following 
criteria: 
 
Unexpected (in terms of nature, severity or frequency) given (a) the research 
procedures that are described in the IRB-approval protocol and informed consent 
document, and (b) the characteristics of the patient population being studied; 
 
Related or possibly related to participation in such research (e.g., there is a 
reasonable possibility that the incident, experience, or outcome may have been 
caused by the procedures involved in such research); and 
 
Suggests that the research places patients or others at a greater risk of harm 
(including physical, psychological, economic or social harm) than was previously 
known or recognized. 
 
11.4 
METHODS AND TIMING FOR ASSESSING AND RECORDING 
SAFETY VARIABLES 
The investigator is responsible for ensuring that all AEs and serious adverse events 
(SAEs) that are observed or reported during the study are collected and reported to the 
FDA, appropriate IRB(s), and study collaborators, Genentech, Inc., and Halozyme in 
accordance with CFR 312.32 (Investigational New Drug [IND] Safety Reports).  
Adverse Event Reporting Period 
The study period during which adverse events must be reported is normally defined as 
the period from the initiation of any study procedures (e.g., after the first dose of study 
treatment) to the end of the study treatment (e.g., last dose of study treatment) and/or 
follow-up. The recording of AEs will begin at the start of the administration of the first 
dose of a study medication, with the exception of study-procedure-associated SAEs. Any 
AE that occurs after the time of ICF signature will be recorded as an SAE if the event is 
associated with a study procedure and meets criteria of seriousness, even if the subject 
has not yet received any study medication. For this study, the study treatment follow-
up is defined as 30 days following the last administration of study treatment, or 30 
days following the decision to remove the patient from study treatment, 
whichever is earliest. After this period, investigators should only report SAEs that are 
attributed to prior study treatment. 
Assessment of Adverse Events 
All AEs and SAEs whether volunteered by the patient, discovered by study personnel 
during questioning, or detected through physical examination, laboratory test, or other 
means will be reported appropriately. Each reported AE or SAE will be described by its 
duration (i.e., start and end dates), regulatory seriousness criteria if applicable,

suspected relationship to atezolizumab and/or PEGPH20 (see following guidance), and 
actions taken. 
To ensure consistency of AE and SAE causality assessments, investigators should 
apply the following general guideline: 
<HV
There is a plausible temporal relationship between the onset of the AE and 
administration of the atezolizumab and/or PEGPH20, and the AE cannot be readily 
explained by the patient s clinical state, intercurrent illness, or concomitant therapies; 
and/or the AE follows a known pattern of response to the atezolizumab and/or 
PEGPH20; and/or the AE abates or resolves upon discontinuation of the atezolizumab 
and/or PEGPH20 or dose reduction and, if applicable, reappears upon re-challenge. 
1R
Evidence exists that the AE has an etiology other than the atezolizumab and/or 
PEGPH20 (e.g., preexisting medical condition, underlying disease, intercurrent illness, 
or concomitant medication); and/or the AE has no plausible temporal relationship to 
atezolizumab and/or PEGPH20 administration (e.g., cancer diagnosed 2 days after first 
dose of study drug). 
Expected adverse events are those adverse events that are listed or characterized in the 
Package Insert or current Investigator Brochure (I.B).  
Unexpected adverse events are those not listed in the Package Insert or current I.B or 
not identified. This includes adverse events for which the specificity or severity is not 
consistent with the description in the Package Insert or I.B. For example, under this 
definition, hepatic necrosis would be unexpected if the Package Insert or I.B only

A consistent methodology for eliciting AEs at all patient evaluation time points should be 
adopted. Examples of non-directive questions include:

How have you felt since your last clinical visit?  
x 
Have you had any new or changed health problems since you were last here?

Investigators should use correct medical terminology/concepts when reporting AEs or 
SAEs. Avoid colloquialisms and abbreviations. 
D 'LDJQRVLVYV6LJQVDQG6\PSWRPV
If known at the time of reporting, a diagnosis should be reported rather than individual 
signs and symptoms (e.g., record only liver failure or hepatitis rather than jaundice, 
asterixis, and elevated transaminases). However, if a constellation of signs and/or 
symptoms cannot be medically characterized as a single diagnosis or syndrome at the 
time of reporting, it is acceptable to report the information that is currently available. If a 
diagnosis is subsequently established, it should be reported as follow-up information. 
E 'HDWKV
All deaths that occur during the protocol-specified AE reporting period (see 
Section 11.4), regardless of attribution, will be reported to the appropriate parties. When 
recording a death, the event or condition that caused or contributed to the fatal outcome 
should be reported as the single medical concept. If the cause of death is unknown and 
cannot be ascertained at the time of reporting, report Unexplained Death . 
F 3UHH[LVWLQJ0HGLFDO&RQGLWLRQV
A preexisting medical condition is one that is present at the start of the study. Such 
conditions should be reported as medical and surgical history. A preexisting medical 
condition should be re-assessed throughout the trial and reported as an AE or SAE only 
if the frequency, severity, or character of the condition worsens during the study. When 
reporting such events, it is important to convey the concept that the preexisting condition 
has changed by including applicable descriptors (e.g., more frequent headaches ). 
G +RVSLWDOL]DWLRQVIRU0HGLFDORU6XUJLFDO3URFHGXUHV
Any AE that results in hospitalization or prolonged hospitalization should be documented 
and reported as an SAE. If a patient is hospitalized to undergo a medical or surgical 
procedure as a result of an AE, the event responsible for the procedure, not the 
procedure itself, should be reported as the SAE. For example, if a patient is hospitalized 
to undergo coronary bypass surgery, record the heart condition that necessitated the 
bypass as the SAE. 
Hospitalizations for the following reasons do not require reporting: 
x 
Hospitalization or prolonged hospitalization for diagnostic or elective surgical 
procedures for preexisting conditions 
x 
Hospitalization or prolonged hospitalization required to allow efficacy measurement 
for the study or 
x 
Hospitalization or prolonged hospitalization for scheduled therapy of the target 
disease of the study

e. Pregnancy 
If a female patient becomes pregnant while receiving the study drug or within 5 months 
after the last dose of study drug, a report should be completed and expeditiously 
submitted to Columbia University who will report on behalf of all sites to its collaborators, 
Genentech, Inc., and Halozyme. Follow-up to obtain the outcome of the pregnancy 
should also occur. Abortion, whether accidental, therapeutic, or spontaneous, should 
always be classified as serious, and expeditiously reported as an SAE. Similarly, any 
congenital anomaly/birth defect in a child born to a female patient exposed to the 
atezolizumab and/or PEGPH20 should be reported as an SAE. 
f. 
Post-Study Adverse Events 
The investigator should expeditiously report any SAE occurring after a patient has 
completed or discontinued study participation if attributed to prior exposure to 
atezolizumab and/or PEGPH20. If the investigator should become aware of the 
development of cancer or a congenital anomaly in a subsequently conceived offspring of 
a female patient who participated in the study, this should be reported as an SAE. 
For studies involving collection of survival data and follow up until progression free 
period the investigator after the end of the adverse event reporting period (defined as 30 
days after the last dose of study drug) should report all deaths, (regardless of cause), 
and any serious adverse event including development of cancer or a congenital anomaly 
in a subsequently conceived offspring of a female subject, including pregnancy occurring 
in the partner of a male study subject who participated in the study that is believed to be 
related to prior exposure to study drug 
Case Transmission Verification will be performed by both parties during this period to 
ensure successful transmission of Single case reports. 
g. Abnormal Laboratory Values 
All abnormal laboratory values that are gradable per National Cancer Institute (NCI) 
CTCAE criteria; will be documented as toxicities regardless of grade, attribution, and 
clinical significance. They must be documented in the medical record directly, to include 
the CTCAE grade and applicable attribution pertaining to the investigational products. If 
the laboratory abnormality suggests a disease and/or organ toxicity and/or require 
active management, the suspected cause and course of management should also be 
documented. 
i. 
Adverse Events of Special Interest to be Reported Immediately to the 
Sponsor/Collaborator: Genentech/Roche

Investigator to the Sponsor is required. Such an event might require further investigation 
in order to characterize and understand it. Depending on the nature of the event, rapid 
communication by the trial Sponsor to other parties (e.g., Regulatory Authorities) may 
also be warranted. 
Adverse events listed below are required to be reported by the investigator to 
Genentech, Inc. immediately (< 48 hours, excluding holidays and weekends, after

Safety Reports according to the following guidance and timelines: 
7 Calendar Day Telephone or Fax Report: 
The PI is required to notify the FDA of any fatal or life-threatening adverse event that is 
unexpected and assessed by the Investigator to be possibly related to the use of 
atezolizumab and PEGPH20. An unexpected adverse event is one that is not already 
described in the Atezolizumab and PEGPH20 Investigator Brochure. Such reports are to 
be telephoned or faxed to the FDA and collaborators Genentech/Roche and Halozyme 
within 7 calendar days of first learning of the event. 
15 Calendar Day Written Report 
The PI is also required to notify the FDA and all participating investigators, in a written 
IND Safety Report, of any serious, unexpected AE that is considered reasonably or 
possibly related to the use of atezolizumab and PEGPH20. An unexpected adverse 
event is one that is not already described in the PEGPH20 IB. 
Written IND Safety reports should include an Analysis of Similar Events in accordance 
with regulation 21 CFR§ 312.32. All safety reports previously filed by the investigator 
with the IND concerning similar events should be analyzed and the significance of the

TREATMENT REGIMEN 
12.1.1 
Atezolizumab 
Atezolizumab is a human immunoglobulin (Ig) G1 monoclonal antibody consisting of two 
heavy chains (448 amino acids) and two light chains (214 amino acids) and is 
produced in CHO cells. Atezolizumab was engineered to eliminate Fc-effector function 
via a single amino acid substitution (asparagine to alanine) at position 298 on the 
heavy chain, which results in a non-glycosylated antibody that has minimal binding to

Fc receptors and prevents Fc-effector function at expected concentrations in humans. 
Atezolizumab targets PD-L1 and inhibits its interaction with its receptor, PD-1. 
Atezolizumab also blocks the binding of PD-L1 to B7.1, an interaction that is reported to 
provide additional inhibitory signals to T cells. It is administered as an IV formulation. 
For further details, see the Atezolizumab Investigator s Brochure.

Atezolizumab will be administered on Days 4 and 18 prior to surgery and on Days 1 and 
15 on a 28 day cycle for 2 cycles after surgery. 
The atezolizumab drug product is provided in a single-use, 20-cc USP/Ph. Eur. Type 1 
glass vial as a colorless-to-slightly-yellow, sterile, preservative-free clear liquid solution 
intended for IV administration. The vial is designed to deliver 20 mL (1200 mg) of 
atezolizumab solution but may contain more than the stated volume to enable 
delivery of the entire 20 mL volume. The atezolizumab drug product is formulated as 
60 mg/mL atezolizumab in 20 mM histidine acetate, 120 mM sucrose, 0.04% polysorbate 
20, pH 5.8. 
Atezolizumab must be stored per the manufacturer s label upon receipt until use. 
Atezolizumab vials should not be used beyond the expiration date provided by the 
manufacturer. No preservative is used in the atezolizumab drug product; therefore,

each vial is intended for single use only. Discard any unused portion of drug left in a 
vial. Vial contents should not be frozen or shaken and should be protected from direct 
sunlight. 
For further details, see the current Atezolizumab Investigator s Brochure. 
The dose level of atezolizumab to be tested in this study is 840 mg (equivalent to an 
average body weight-based dose of 15 mg/kg) administered by IV infusion every 
2 weeks for two doses pre- surgery and 4 doses post-surgery. Atezolizumab will be 
delivered in infusion bags with IV infusion lines that have product contacting surfaces 
of polyvinyl chloride (PVC) or polyolefin and 0.2 Pm in-line filters (filter membrane of 
polyethersulfone [PES]). No incompatibilities have been observed between atezolizumab 
and PVC or polyolefin infusion materials (bags or infusion lines). 
Administration of atezolizumab will be performed in a setting with emergency medical 
facilities and staff who are trained to monitor for and respond to medical emergencies. 
The initial dose of atezolizumab will be delivered over 60 (+/- 15) minutes (see Table 14). 
If the first infusion is tolerated without infusion-associated AEs, the second infusion may 
be delivered over 30 (+/- 10) minutes. If the 30-minute infusion is well tolerated, all 
subsequent infusions may be delivered over 30 (+/- 10) minutes. For the first infusion, 
the patient s vital signs (heart rate, respiratory rate, blood pressure, and temperature) 
should be determined within 60 minutes before, during (every 15 [+/- 5] minutes), and 
30 (+/- 10) minutes after the infusion. For subsequent infusions, vital signs will be 
collected within 60 minutes before and within 30 minutes after the infusion. Vital signs 
should be collected during the infusion only if clinically indicated. Patients will be informed 
about the possibility of delayed post-infusion symptoms and instructed to contact their 
study physician if they develop such symptoms.

Table 14 Administration of First and Subsequent Atezolizumab Infusions. 
First Infusion  
Subsequent Infusions 
 
No premedication is permitted. 
 
Vital signs (heart rate, respiratory rate, blood
pressure, and temperature) should be 
recorded within 60 minutes prior to the 
infusion. 
 
Atezolizumab should be infused over 60  
(+/- 15) minutes. 
 
If clinically indicated, vital signs should be 
recorded during the infusion at 15, 30, 45, 
and 60 minutes (+/- 5 minutes for all time 
points) during the infusion and at 30 (+/- 10) 
minutes after the infusion. 
 
Patients should be informed about the 
possibility of delayed post-infusion 
symptoms and instructed to contact their 
study physician if they develop such 
symptoms. 
 
If the patient experienced an infusion-
related reaction with any previous infusion, 
premedication with antihistamines, 
antipyretics, and/or analgesics may be 
administered for subsequent doses at the 
discretion of the investigator. 
 
Vital signs should be recorded within 
60 minutes prior to the infusion. 
 
Atezolizumab should be infused over 
30 (+/-10) minutes if the previous infusion 
was tolerated without an infusion-related 
reaction, or 60 (+/- 15) minutes if the 
patient experienced an infusion- related 
reaction with the previous infusion. 
 
If the patient experienced an infusion-
related reaction with the previous infusion 
or if clinically indicated, vital signs should 
be recorded during the infusion and at 
30 (+/- 5) minutes after the infusion. 
 
No steroid premedication will be allowed for the first dose of atezolizumab. 
Premedication may be administered for Cycles ≥ 2 at the discretion of the treating 
investigator in consultation with the PI. The management of IRRs will be according to 
severity as follows: 
 
In the event that a patient experiences a mild (NCI CTCAE Grade 1) IRR, the 
infusion rate should be reduced to half the rate being given at the time of event 
onset. Once the event has resolved, the investigator should wait for 30 minutes 
while delivering the infusion at the reduced rate. If tolerated, the infusion rate may 
then be increased to the original rate. 
 
In the event that a patient experiences a moderate IRR (NCI CTCAE Grade 2) or 
flushing, fever, or throat pain, the infusion should be immediately interrupted and 
the patient should receive aggressive symptomatic treatment. The infusion should 
be restarted only after the symptoms have adequately resolved to baseline grade. 
The infusion rate at restart should be half of the infusion rate that was in progress at 
the time of the onset of the IRR. 
 
For severe or life-threatening IRRs (NCI CTCAE Grade 3 or 4), the infusion 
should be stopped immediately, and aggressive resuscitation and supportive 
measures should be initiated. Patients experiencing severe or life-threatening 
IRRs will not receive further infusion and will be further managed as clinically 
indicated until the event resolves.

1 Protocol-specified screening procedures that are performed as part of standard of care and within 14 days of Day 1 of Cycle 1 may be used 
for screening purposes. Clinical laboratory studies and baseline CT and or MRI scan must be performed within the 7-day period before Day 
1 of Cycle 1. Screening labs may be used for Cycle 1 Day 1 if performed within 72 hours prior to study visit. 
2 The End-of-Study visit should be scheduled within the 28-day period after the last dose of study drug, or 28 days after removal from study. 
3 Adjuvant modified FOLFIRINOX will be administered as described in Section 9.1.4. 
4 Patients will be seen every 3 months during years 1 through 3 (+/- 14 days) and every six months for years 4 and 5 (+/- 28 days) with blood 
work including CEA and Ca19-9 and imaging as per standard of care surveillance. 
5 Cytologic or histologic proof of PDA needs to be verified by the treating institution pathologist either on the initial diagnosis, or on the 
required pre-treatment biopsy. Pathological report from non-treating institutions is sufficient to consent if tissue sample is unavailable for 
evaluation at time of consent. However, in such a case, PDA diagnosis will need to be confirmed on the pre-treatment biopsy prior to initiation 
of treatment. 
6 A complete physical examination will be performed at screening. All subsequent physical examinations will be focused disease-specific 
exams. Subjects will be under go physical exams as indicated and every other week after surgery until initiation of cycle 2 or deemed not a 
candidate to receive therapy. Physical exam on week 3 after surgery is optional and dependent on clinical necessity. 
7 ECG recordings will be obtained during screening, prior to surgery, and during end-of-study. Patients should be resting in a supine position for at 
least 5 minutes prior to ECG recording.

9 Fresh tumor tissue samples will be collected from all patients by means of a biopsy performed at study entry. Adequate tissue collection to 
confirm diagnosis as deemed by the on-site pathologist on a preliminary review will be required for eligibility. If diagnosis is not 
confirmed, an attempt to repeat tumor biopsy is allowed if deemed safe, patient agreeable to repeat procedure, and performed at least 
3 days prior to scheduled start of therapy. Optional tumor biopsy at time of recurrence (listed here as on follow-up). 
10 TSH, free T3 (or total T3 for sites where free T3 is not performed), free T4, and AM cortisol will be assessed at screening and on pre-surgery, 
Day 1 of Cycle 2, on end of study, and as clinically appropriate. 
11 At screening, patients without a prior positive HIV test result will undergo an HIV test, unless not permitted per local regulations. Patients will also 
be tested for HBsAg, HBsAb, total HBcAb, and HCV antibody. If a patient has a negative HBsAg test and a positive total HBcAb test at 
screening, an HBV DNA test should be performed. If a patient has a positive HCV antibody test at screening, an HCV RNA test must also be 
performed to determine if the patient has an active HCV infection. 
12 All women of childbearing potential will have a serum pregnancy test at screening, within 14 days prior to initiation of study treatment. Urine 
or serum pregnancy tests will be performed at specified subsequent visits. If a urine pregnancy test is positive, it must be confirmed by a 
serum pregnancy test.

contrast is contraindicated (i.e., in patients with contrast allergy or impaired renal clearance), a non-contrast CT scan of the chest may be 
performed and MRI scans (with IV contrast) of the abdomen and pelvis should be performed. Bone scans and CT scans of the neck should

All patients will undergo preoperative multiphasic CT (MDCT) scan for local staging 
using a dedicated pancreatic tumor imaging protocol. MRI of the abdomen may be used 
if unable to obtain contrasted CT scan or better definition for staging. 
&73URWRFRO
The multiphasic CT (MDCT) pancreatic tumor protocol consists of three phases: pre- 
contrast, post-contrast pancreatic parenchymal phase (40-50 seconds after IV contrast 
injection) and post-contrast portal venous phase (65-70 seconds after IV contrast 
injection). The rate of IV contrast injection will be 4-5 mL/sec, iodine concentration 
= 300 mg/mL, and the volume of injected contrast will be based on patient s body 
weight (100 mL for patients weighing  250 lb and 150 mL for patients weighing 
>250 lb). In addition to IV contrast, enteric contrast will be administered. CT images will 
be acquired at slice thickness of d 1 mm and reconstructed for axial sections (2-5 mm 
slice thickness) and multiplanar coronal and sagittal reformations (2-3 mm thickness).

Abdominal MRI without and with IV contrast will be performed if there is any 
contraindication to iodinated CT contrast, or for further assessment of the liver 
parenchyma, or better definition of staging. MRI pancreatic protocol includes T1 
weighted imaging using in and opposed phase, axial and coronal T2 weighted, diffusion 
weighted, fat suppressed dynamic pre/post IV contrast gradient, echo T1 weighted 
imaging with slice thickness (interpolated to 2-3 mm), and heavily T2 weighted MRCP

ANTITUMOR EFFECT – SOLID TUMORS 
For the purposes of this study, patients should be re-evaluated for recurrence as 
indicated in the schedule of assessments. 
Treatment Beyond Initial Radiographic Recurrence 
In studies of immunotherapeutic agents, complete response, partial response, and 
stable disease have each been shown to occur after radiographic evidence of an 
apparent increase in tumor burden. This initial increase in tumor burden caused by 
immune cell infiltration in the setting of a T-cell response has been termed pseudo-
progression (Hales et al. 2010). In Study PCD4989g, evidence of tumor growth 
followed by a response was observed in several tumor types. In addition, in some 
responding patients with radiographic evidence of progression, biopsies of new lesions or 
areas of new growth in existing lesions revealed immune cells and no viable cancer 
cells. Because of the potential for a response after pseudo-recurrence, this study will 
allow patients randomly assigned to immunotherapy-based treatment arms to continue 
combination treatment after apparent radiographic recurrence per immune-modified 
Response Evaluation Criteria in Solid Tumors (RECIST), provided the benefit-risk ratio is 
judged to be favorable by the investigator. 
Patients should be discontinued for unacceptable toxicity or loss of clinical benefit as 
determined by the investigator after an integrated assessment of radiographic and 
biochemical data, local biopsy results (if available), and clinical status (e.g., 
symptomatic deterioration such as pain secondary to disease). Because of the 
possibility of an initial increase in tumor burden caused by immune cell infiltration in 
the setting of a T-cell response (termed pseudo-progression) with atezolizumab 
treatment, radiographic recurrence per RECIST v1.1 may not be indicative of true 
disease recurrence. In the absence of unacceptable toxicity, patients who meet criteria 
for disease recurrence per RECIST v1.1 while receiving treatment with atezolizumab or 
other treatments will be permitted to continue treatment if they meet all of the following 
criteria: 
 
Evidence of clinical benefit, as determined by the investigator following a 
review of all available data 
 
Absence of symptoms and signs (including laboratory values, such as new or 
worsening hypercalcemia) indicating unequivocal recurrence of disease 
 
Absence of decline in ECOG Performance Status that can be attributed to disease 
recurrence

Absence of tumor recurrence at critical anatomical sites (e.g., leptomeningeal 
disease) that cannot be managed by protocol-allowed medical interventions

of continuing study treatment at the time of initial apparent disease recurrence.

Increasing clinical experience indicates that traditional response criteria (e.g., 
RECIST v1.1 and World Health Organization [WHO] criteria) may not adequately assess 
the activity of immunotherapeutic agents because initial radiographic evidence of 
disease progression (or in this case, disease recurrence) does not necessarily 
reflect therapeutic failure. Patients can experience a response in the presence of new 
lesions or after an increase in tumor burden. Thus, this study will employ immune-
modified RECIST for tumor assessments to account for the possible appearance of new 
lesions and allow radiographic recurrence to be confirmed at a subsequent 
assessment. It is required that radiographic recurrence be confirmed at a subsequent 
tumor assessment to take into account the potential for pseudo-recurrence (caused 
by immune cell infiltration). Given the proposed immunomodulatory mechanism of 
action of atezolizumab and the possibility of observing delayed responses, use of 
immune-modified RECIST will allow for the capture of a greater proportion of potential 
responses and allow patients to derive maximum clinical benefit. Immune-modified 
Response Evaluation Criteria in Solid Tumors (RECIST), as described within this 
appendix, were adapted from RECIST, Version 1.1 (v1.1) (Eisenhauer et al. 2009) in the 
same manner that immune- related response criteria were adapted from WHO criteria 
(Wolchok et al. 2009) and RECIST v1.0 (Nishino et al. 2014). When not otherwise 
specified, RECIST v1.1 conventions will apply. Differences between immune-modified 
RECIST and RECIST v1.1 are summarized Table 16.

Conventional response criteria may not be adequate to characterize the anti-tumor 
activity of immunotherapeutic agents like atezolizumab, which can produce delayed 
responses that may be preceded by initial apparent radiographic progression, 
including the appearance of new lesions. Therefore, immune-modified response 
criteria have been developed to incorporate new lesions into the assessment of total 
tumor burden and allow radiographic progression to be confirmed at a subsequent 
assessment. Immune-modified Response Evaluation Criteria in Solid Tumors 
(RECIST), as described within this appendix, were adapted from RECIST, Version 1.1 
(v1.1), in the same manner that immune-related response criteria were adapted from 
WHO criteria and RECIST v1.0 (Ritchie et al. 2015; H nzelmann S et al. 2013). When 
not otherwise specified, RECIST v1.1 conventions will apply. Differences between 
immune-modified RECIST and RECIST v1.1 are summarized in Table 16.

TUMOR MEASURABILITY 
At baseline, tumor lesions/lymph nodes will be categorized as measurable or non-
measurable as described below. All measurable and non-measurable lesions should be 
assessed at screening and at subsequent protocol-specified tumor assessment time 
points. Additional assessments may be performed as clinically indicated for suspicion 
of recurrence.

DEFINITION OF MEASURABLE LESIONS 
Tumor Lesions 
Tumor lesions must be accurately measured in at least one dimension (longest 
diameter in the plane of measurement is to be recorded) with a minimum size as 
follows: 
 
10 mm by CT or MRI scan (CT/MRI scan slice thickness/interval   5 mm) 
 
10-mm caliper measurement by clinical examination (lesions that cannot be 
accurately measured with calipers should be recorded as non-measurable) 
 
20 mm by chest X-ray 
 
Malignant Lymph Nodes 
To be considered pathologically enlarged and measurable, a lymph node must be 
 15 mm in the short axis when assessed by CT scan (CT scan slice thickness 
recommended to be   5 mm). At baseline and follow-up, only the short axis will be 
measured and followed. Additional information on lymph node measurement is 
provided below (see "Identification of Target and Non-Target Lesions," "New Lesions," 
and "Calculation of Sum of Diameters"). 
DEFINITION OF NON-MEASURABLE LESIONS 
Non-measurable tumor lesions encompass small lesions (longest diameter < 10 mm or 
pathological lymph nodes with short axis  10 mm but   15 mm) as well as truly non-
measurable lesions. Lesions considered truly non-measurable include leptomeningeal 
disease, ascites, pleural or pericardial effusion, inflammatory breast disease, 
lymphangitic involvement of skin or lung, peritoneal spread, and abdominal 
mass/abdominal organomegaly identified by physical examination that is not 
measurable by reproducible imaging techniques. 
SPECIAL CONSIDERATIONS REGARDING LESION MEASURABILITY 
Bone lesions, cystic lesions, and lesions previously treated with local therapy require 
particular comment, as outlined below. 
Bone Lesions: 
 
Technetium-99m bone scans, sodium fluoride PET scans, and plain films are not 
considered adequate imaging techniques for measuring bone lesions. However, 
these techniques can be used to confirm the presence or disappearance of bone 
lesions. 

Columbia University Medical Center 
Herbert Irving Comprehensive Cancer Center 
Version Date: 05/13/2019 
 
111 
 
 
Lytic bone lesions or mixed lytic-blastic lesions with identifiable soft tissue 
components that can be evaluated by cross-sectional imaging techniques such as 
CT scan or MRI can be considered measurable lesions if the soft tissue component 
meets the definition of measurability described above. 
 
Blastic bone lesions are non-measurable. 
 
Cystic Lesions: 
 
Lesions that meet the criteria for radiographically defined simple cysts should not 
be considered malignant lesions (neither measurable nor non-measurable) 
because they are, by definition, simple cysts. 
 
Cystic lesions thought to represent cystic metastases can be considered 
measurable lesions if they meet the definition of measurability described above. 
However, if non-cystic lesions are present in the same patient, these are preferred 
for selection as target lesions. 
 
Lesions with Prior Local Treatment: 
 
Tumor lesions situated in a previously irradiated area or in an area patiented to 
other loco- regional therapy are usually not considered measurable unless there 
has been demonstrated progression in the lesion. 
 
METHODS FOR ASSESSING LESIONS 
All measurements should be recorded in metric notation, using calipers if clinically 
assessed. All baseline evaluations should be performed as close as possible to the 
treatment start and never more than 4 weeks before the beginning of the treatment. 
The same method of assessment and the same technique should be used to 
characterize each identified and reported lesion at baseline and during the study. 
Imaging-based evaluation should always be the preferred option. 
CLINICAL LESIONS 
Clinical lesions will only be considered measurable when they are superficial and 
 10 mm in diameter as assessed using calipers (e.g., skin nodules). For the case of skin 
lesions, documentation by color photography, including a ruler to estimate the size of 
the lesion, is suggested. 
CHEST X-RAY 
Chest CT scan is preferred over chest X-ray, particularly when recurrence is an 
important endpoint, because CT is more sensitive than X-ray, particularly in identifying 
new lesions. However, lesions on chest X-ray may be considered measurable if they are 
clearly defined and surrounded by aerated lung.

&7$1'05,6&$16
CT is the best currently available and reproducible method to measure lesions selected for 
response assessment. In this guideline, the definition of measurability of lesions on CT 
scan is based on the assumption that CT slice thickness is d 5 mm. When CT scans have 
slice thickness of ! 5 mm, the minimum size for a measurable lesion should be twice the 
slice thickness. MRI is also acceptable. If prior to enrollment it is known that a patient 
is unable to undergo CT scans with IV contrast because of allergy or renal 
insufficiency, the decision as to whether a non-contrast CT scan or MRI (without IV 
contrast) will be used to evaluate the patient at baseline and during the study should 
be guided by the tumor type under investigation and the anatomic location of the 
disease. For patients who develop contraindications to contrast after baseline contrast 
CT scan is done, the decision as to whether non-contrast CT scan or MRI (enhanced or 
non-enhanced) will be performed should also be based on the tumor type and the 
anatomic location of the disease, and should be optimized to allow for comparison with 
the prior studies if possible. Each case should be discussed with the site designated 
radiologist to determine if substitution of these other approaches is possible and, if 
not, the patient should be considered not evaluable from that point forward. Care must 
be taken in measurement of target lesions and interpretation of non-target disease or 
new lesions on a different modality, because the same lesion may appear to have a 
different size using a new modality. 
)'*3(7While FDG-PET response assessments need additional study, it is 
sometimes reasonable to incorporate the use of FDG-PET scanning to complement CT 
scanning in assessment of recurrence (particularly possible ’new’ disease). New lesions 
on the basis of FDG-PET imaging can be identified according to the following algorithm: 
x 
Negative FDG-PET at baseline, with a positive FDG-PET at follow-up is a sign of 
progressive disease (PD) based on a new lesion. 
x 
No FDG-PET at baseline and a positive FDG-PET at follow-up: If the positive 
FDG-PET at follow-up corresponds to a new site of disease confirmed by CT 
scan, this is PD which should be confirmed by a biopsy. If the positive FDG-PET 
at follow-up is not confirmed as a new site of disease on CT, additional follow-up 
CT scans are needed to determine if there is truly progression occurring at that site 
(if so, the date of PD will be the date of the initial abnormal FDG-PET scan). If the 
positive FDG-PET at follow-up corresponds to a pre-existing site of disease on CT 
that is not progressing on the basis of the anatomic images, this is not PD. 
x 
FDG-PET may be used to upgrade a response to a complete response (CR) in a 
manner similar to a biopsy in cases where a residual radiographic abnormality is 
thought to represent fibrosis or scarring. The use of FDG-PET in this circumstance 
should be prospectively described in the protocol and supported by disease-specific 
medical literature for the indication. However, it must be acknowledged that both

approaches may lead to false positive CR due to limitations of FDG-PET and 
biopsy resolution/sensitivity. 
 
Note: A positive  FDG-PET scan lesion means one that is FDG avid with an uptake 
greater than twice that of the surrounding tissue on the attenuation corrected image.

Baseline scan should contain pancreas-specific mass to be considered eligible, and no 
measurable lesion considered concerning for metastatic disease. All measurable non-
pancreatic lesions should be biopsied to confirm benign lesion. 
Target lesions present at the time of recurrence should be selected on the basis of 
their size (lesions with the longest diameter) and be representative of all involved 
organs, but in addition should lend themselves to reproducible repeated 
measurements. It may be the case that, on occasion, the largest lesion does not lend 
itself to reproducible measurement, in which circumstance the next largest lesion that 
can be measured reproducibly should be selected. ,IDQHZOHVLRQLVLGHQWLILHG RQ

Lymph nodes merit special mention because they are normal anatomical structures 
that may be visible by imaging even if not involved by tumor. As noted above, 
pathological nodes that are defined as measurable and may be identified as target 
lesions must meet the criterion of a short axis of t 15 mm by CT scan. Only the short 
axis of these nodes will contribute to the baseline sum. The short axis of the node is 
the diameter normally used by radiologists to judge if a node is involved by solid tumor. 
Lymph node size is normally reported as two dimensions in the plane in which the image 
is obtained (for CT, this is almost always the axial plane; for MRI, the plane of 
acquisition may be axial, sagittal, or coronal). The smaller of these measures is the short 
axis. For example, an abdominal node that is reported as being 20 mm u 30 mm has a 
short axis of 20 mm and qualifies as a malignant, measurable node. In this example, 
20 mm should be recorded as the node measurement. All other pathological nodes

Version Date: 05/13/2019 
 
114 
 
(those with short axis  10 mm but  15 mm) should be considered non-target lesions. 
Nodes that have a short axis of  10 mm are considered non-pathological and should 
not be recorded or followed. 
All lesions (or sites of disease) not selected as target lesions (measurable or non-
measurable), including pathological lymph nodes, should be identified as non-target 
lesions and should also be recorded at baseline. Measurements are not required. It is 
possible to record multiple non-target lesions involving the same organ as a single item 
on the CRF (e.g., "multiple enlarged pelvic lymph nodes" or "multiple liver metastases"). 
NEW LESIONS 
New lesions identified after baseline will be evaluated for measurability with use of 
the same criteria applied to prospective target lesions at baseline per RECIST (e.g., non-
lymph node lesions must be ≥10 mm on the longest diameter; new lymph nodes must 
be ≥15 mm on the short axis [see note below]). All new lesions (measurable or non-
measurable) must be assessed and recorded at the time of identification and at all 
subsequent tumor assessment time points. 
Up to a maximum of five measurable new lesions total (and a maximum of two lesions 
per organ) can be included in the calculation of tumor burden that is performed as part of 
the tumor response evaluation. New lesion types that would not qualify as target 
lesions per RECIST cannot be included in the calculation of tumor burden and thus 
will not affect overall tumor response evaluation. New lesions that are not measurable 
at first appearance but meet measurability criteria at a subsequent time point can be 
included in the tumor response evaluation from that point on, if the maximum number of 
measurable new lesions has not been reached. 
Note regarding new lymph node lesions: If at first appearance the short axis of a 
lymph node lesion is ≥15 mm, it will be considered a measurable new lesion. If at first 
appearance the short axis of a lymph node lesion is ≥10 mm and  15 mm, the lymph 
node will not be considered measurable but will still be considered a new lesion and 
should be identified as a non-measurable new lesion. If at first appearance the short axis 
of a lymph node is  10 mm, the lymph node should not be considered pathological and 
should not be considered a new lesion. A lymph node can subsequently become 
measurable, when the short axis is ≥15 mm. 
CALCULATION OF SUM OF DIAMETERS 
A sum of the diameters (longest diameter for non-lymph node lesions, short axis for 
lymph node lesions) will be calculated for all target lesions at baseline as a measure of 
tumor burden. At each subsequent tumor assessment, a sum of the diameters 
(longest diameter for non-lymph node lesions, short axis for lymph node lesions) will be 
calculated for all target lesions plus measurable new lesions (up to five new lesions,

Herbert Irving Comprehensive Cancer Center 
Version Date: 05/13/2019 
 
115 
 
with a maximum of two new lesions per organ) that have emerged after baseline. 
Hence, each net percentage change in tumor burden per assessment accounts for 
the size and growth kinetics of both old lesions and new lesions as they appear. 
Measuring Lymph Nodes 
If at first appearance the short axis of a new lymph node lesion is  15 mm, it will be 
considered a measurable new lesion and may be included in the sum of the diameters. 
If the new lymph node lesion is included in the sum of diameters, it will continue to be 
measured and included in the sum of diameters at subsequent time points, even if the 
short axis decreases to  15 mm (or even  10 mm). However, if it subsequently 
decreases to  10 mm and all other lesions are no longer detectable or have also 
decreased to a short axis of  10 mm (if lymph nodes), a response assessment of 
complete response may be assigned. 
Lymph nodes should always have the actual short axis measurement recorded 
(measured in the same anatomical plane as the baseline examination), even if the node 
regresses to  10 mm during the study. Thus, when lymph nodes are included in the sum 
of diameters, the sum may not be zero even if complete response criteria are met, 
because a normal lymph node is defined as having a short axis of  10 mm. 
Measuring Lesions That Become Too Small to Measure 
During the study, all target lesions and up to five measurable new lesions (lymph 
node and non-lymph node) should have their actual measurements recorded at each 
subsequent evaluation, even when very small (e.g., 2 mm). However, sometimes 
lesions or lymph nodes become so faint on CT scan that the radiologist may not feel 
comfortable assigning an exact measurement and may report them as being too small 
to measure. When this occurs, it is important that a value be recorded on the CRF, as 
follows: 
 
If it is the opinion of the radiologist that the lesion has likely disappeared, the 
measurement should be recorded as 0 mm. 
 
If the lesion is believed to be present and is faintly seen but too small to measure, 
a default value of 5 mm should be assigned and "too small to measure" should be 
ticked. (Note: It is less likely that this rule will be used for lymph nodes because 
they usually have a definable size when normal and are frequently surrounded 
by fat such as in the retroperitoneum; however, if a lymph node is believed to be 
present and is faintly seen but too small to measure, a default value of 5 mm 
should be assigned in this circumstance as well, and "too small to measure" 
should also be ticked). 
 
To reiterate, however, if the radiologist is able to provide an actual measurement, that 
measurement should be recorded, even if it is  5 mm, and in that case "too small to 
measure" should not be ticked.

Measuring Lesions That Split or Coalesce on Treatment 
When non-lymph node lesions fragment, the longest diameters of the fragmented 
portions should be added together to calculate the sum of diameters. Similarly, as lesions 
coalesce, a plane between them may be maintained that would aid in obtaining 
maximal diameter measurements of each individual lesion. If the lesions have truly 
coalesced such that they are no longer separable, the vector of the longest diameter in 
this instance should be the maximum longest diameter for the coalesced lesion. 
EVALUATION OF NON-TARGET LESIONS AND NON-MEASURABLE NEW 
LESIONS 
Measurements are not required for non-target lesions or non-measurable new lesions. 
Non-target lesions should be noted at baseline, and non-measurable new lesions 
should be noted at the time of identification. At subsequent evaluations, non-target 
lesions and non-measurable new lesions will be categorized as "present" or "absent." 
After baseline, changes in non-target lesions or non-measurable new lesions (or 
measurable new lesions in excess of five total or two per organ) will contribute only in 
the assessment of complete response (i.e., a complete response is attained only with 
the complete disappearance of all tumor lesions, including non-target lesions and 
non-measurable new lesions) and will not be used to assess progressive disease. 
DEFINITION OF RESPONSE CRITERIA 
Definitions of the criteria used to determine objective tumor response are provided 
below: 
 
Progressive disease (PD): At least a 20% increase in the sum of diameters of all 
target lesions plus measurable new lesions (up to a maximum of five total or 
two per organ), taking as reference the smallest sum of diameters on study 
(including baseline) 
In addition to the relative increase of 20%, the sum of diameters must also 
demonstrate an absolute increase of  5 mm. 
New lesions alone do not qualify as progressive disease. However, their 
contribution to total tumor burden is factored into the sum of the diameters, which is 
used to determine the overall immune-modified RECIST tumor response. 
 
Stable disease (SD): Neither sufficient shrinkage to qualify for CR or partial 
response (PR) nor sufficient increase to qualify for PD. 
 
MISSING ASSESSMENTS AND NOT-EVALUABLE DESIGNATION 
When no imaging/measurement is done at all at a particular time point, the patient is not 
evaluable at that time point. If measurements are made on only a subset of target or 
measurable new lesions at a time point, usually the case is also considered not 
evaluable at that time point, unless a convincing argument can be made that the 

Columbia University Medical Center 
Herbert Irving Comprehensive Cancer Center 
Version Date: 05/13/2019 
 
117 
 
contribution of the individual missing lesions would not change the assigned time point 
response. This would be most likely to happen in the case of treatment beyond 
recurrence. For example, if a patient had a recurrence sum of 50 mm with three 
measured lesions and during the study only two lesions were assessed, but those gave a 
sum of 80 mm, the patient will have achieved confirmed recurrence status, regardless 
of the contribution of the missing lesion. 
SPECIAL NOTES ON RESPONSE ASSESSMENT 
Patients with a global deterioration in health status requiring discontinuation of treatment 
without objective evidence of disease recurrence at that time should be reported as 
having "symptomatic deterioration." Every effort should be made to document 
objective recurrence even after discontinuation of treatment. Symptomatic 
deterioration is not a descriptor of an objective response; it is a reason for stopping 
study therapy. The objective response status of such patients is to be determined by 
evaluation of target and non-target lesions, as well as new lesions. 
Stopping Rules 
The study may be discontinued if the study is terminated by the data and safety 
monitoring committee, the FDA, or other regulatory authorities. 
A safety committee of participating surgeons and medical oncologists at CUMC and 
Memorial Sloan Kettering Cancer Center will convene on a regularly scheduled basis 
to discuss study conduct. If greater than two of the 20 patients per cohort are 
unable to undergo surgery, or greater than four of the 20 patients per cohort 
have a greater than 14-day delay in surgery, deemed related to study treatment, 
enrollment to that arm will be halted and an analysis performed by the PI. The 
PI, in consultation with the safety committee, will either modify the treatment regimen 
or discontinue the arm if an alternate safe regimen is not deemed feasible. 
Other Response Parameters 
Exploratory endpoints will be evaluated on tissue samples obtained from core 
biopsies and resected tissue for co-immunofluoresence for immune markers, 
RNA-sequence analysis for expression profile within neoplastic epithelium and 
stroma, and other analysis. Please refer to the laboratory manual describing sample 
collection procedures.

This is a randomized phase 2 study with a biological endpoint aimed at comparing 
CD8+ T-cell count within the resected tumor with neoadjuvant atezolizumab vs 
atezolizumab + PEGPH20 or other combinations at the time of surgery. All patients who 
meet inclusion/exclusion criteria and who receive 1 dose of study related treatment will 
be considered evaluable.

The primary endpoint is change in the number of intratumoral CD8+ T cells at time of 
surgery between treatment arm(s) compared to the atezolizumab arm. 
Briefly, to obtain CD8+ T-cell count, we will probe formalin-fixed paraffin-embedded 
(FFPE) biopsy and resected tissue sections with distinct markers using quantitative 
multiplex immunofluorescence (qmIF)(Deng et al. 2016). This process involves a novel 
tyramide signal amplification (TSA) multiplexing technique that enables serial staining on 
the same section enabling simultaneous examination of up to eight epitopes. Multiple 
markers for distinct cell types will be used to investigate the tumor microenvironment. 
Some of these include, but are not limited to, pan T-cell (CD3), CD8+ T-cell (CD8), 
CD4+ T-cell (CD4), regulatory T-cell (FOXP3), PD-L1, myeloid (CD68), neoplastic 
(CK19), and nuclear (DAPI) markers. Images are visualized using Vectra
 microscope 
and analyzed using inForm  Tissue Finder
 analysis software, which uses algorithms 
for machine learning based on cell morphology which includes membrane phenotype 
and cytoplasmic and nuclear stains, each cell is also assigned a coordinate on the slide 
for spacial analysis. This information is used to perform nearest neighbor analysis to

determine the location of cells relative to each other. Distance between immune 
subtypes and neoplastic cells will be analyzed to correlate with tumor cell death and 
clinical outcome. A designated gastrointestinal (GI) pathologist will review each 
hematoxylin and eosin (H&E) stained serial section and qmIF slide to oversee the 
process. Representative areas within the slide will be used for cell counts and nearest 
neighbor analysis. Simple immunohistochemistry (IHC) will be used in unforeseen 
circumstances where qmIF is not possible to quantitate CD8+ T cells. 
Secondary Endpoint: 
a) To estimate the 18-month survival rate and overall survival in patients treated 
with atezolizumab vs atezolizumab + PEGPH20 followed by surgery and 
adjuvant therapy. 
b) To determine the R0 resection rates with atezolizumab vs atezolizumab + PEGPH20 
administered in the neoadjuvant setting. 
c) 
To determine the safety profile with atezolizumab vs atezolizumab + PEGPH20 
followed by surgery and adjuvant therapy. 
d) To evaluate Ca 19-9 biomarker responses to atezolizumab with or without 
PEGPH20 in the neoadjuvant setting. 
e) To evaluate patterns of failure following neoadjuvant atezolizumab with or without 
PEGPH20 and surgery. 
f) 
Intratumoral CD8+ T cells after neoadjuvant atezolizumab alone or combination with 
PEGPH20 at time of surgery will be compared to intratumoral CD8+ T cells within 
resected tumors after no neoadjuvant therapy from matched historical controls. 
 
Exploratory Endpoints: 
a) To isolate the epithelium and stromal tumor compartments for protein 
expression profiling using RNA-seq for subtype classification of PDA. This will be 
performed using LCM on resected tissue samples from patients treated with 
atezolizumab vs atezolizumab + PEGPH20. 
b) To quantitate the change in CD8+ T cells within paired pre-treatment biopsy and 
on-treated resected tumor treated with atezolizumab vs atezolizumab + PEGPH20. 
c) 
To quantitate distinct immune subtypes within on-treatment tumor treated with 
atezolizumab vs atezolizumab + PEGPH20 by quantitative multiplex 
immunofluorescence. 
d) To quantitate the change in immune subtypes within paired pre-treatment biopsy 
and on-treatment resected tumor treated with atezolizumab vs atezolizumab + 
PEGPH20. 
 
Sample size justification: 
For the primary endpoint of CD8+ T-cell infiltration, a group sample size of 17 achieves 
at least 80% power to detect a difference of 1 SD with a significance level (alpha) of

0.05 using a two-sided two-sample t-test. Since PDA tumors contain sparse CD8+ T 
cells, we expect that a two- fold increase in CD8+ T- cell infiltration will have a 
clinically meaningful effect. From our experience, we estimate an attrition rate of 
15% with inevaluable tissue; therefore, 20 patients per cohort will be recruited. 
Study Arms: 
Arm A. Atezolizumab alone 
Arm B. Atezolizumab with PEGPH20 
Additional arms will be added as deemed appropriate. 
Patients will be randomly assigned to one of the study arms with an approximately equal 
ratio.

ANALYSIS OF PRIMARY, SECONDARY ENDPOINTS AND 
EVALUATION OF TISSUE  
Primary Analysis: 
The CD8+ T-cell count within the tumor with neoadjuvant atezolizumab vs 
atezolizumab + PEGPH20 or other combinations at the time of surgery will be reported 
using means and standard deviations by group and will be compared using a two-
sample T-test. If the data are not normally distributed, non-parametric models such as 
the Wilcoxon Rank Sum test will be used. Moreover, the distribution of CD8+ T-cell count 
by treatment arm will be assessed using box plots, histograms, and q-q plots. 
Secondary Analysis: 
Overall survival (OS) and Recurrence-free survival 
Overall survival and recurrence-free survival (RFS) will be estimated using the 
Kaplan Meier method. We will calculate and report the 18-months OS rate and the 
median OS/RFS along with their 95% confidence intervals. Kaplan Meier graphs will be 
done. OS and RFS will be compared by treatment arm using the log-rank test. 
R0 Resection Rate 
R0 resection rate is defined by the proportion of patients in whom an R0 resection was 
achieved during surgery which is defined by complete removal of macroscopic 
tumor which contains negative microscopic surgical margins. The R0 resection rate will 
be estimated by the number of patients in whom R0 resection was performed divided 
by total number of patients in each study arm. The R0 resection rate will be reported

Statistical analysis of RNA-Seq expression data derived from samples of the treatment 
arms will be carried out in the R environment for statistical computing (Team RDC 
2016). In order to identify differentially expressed genes between the conditions, we 
will make use voom-limma framework (Ritchie et al. 2015). Briefly, linear models are fit 
for each gene to estimate the coefficients (= effect size) and their standard error. 
Empirical Bayes moderated t-statistics and their associated p-values are then used to 
assess the significance of the observed expression changes. 
In order to evaluate concerted differences of biologically related genes, single sample 
gene set enrichment will be employed via the GSVA R package (H nzelmann et al. 
2013), which produces a gene-set by sample matrix with approximately normally 
distributed enrichment scores which can then be compared between treatment arms 
using for example linear models. Detailed statistical plan is as described in the 
manuscript [Kenneth Olive, submitted].

CD8+ T cell infiltration: 
Exploratory studies will measure CD8+ T-cell numbers by immunohistochemistry (IHC) 
or qmIF performed to determine tumor-infiltrating lymphocyte infiltration from paired fresh 
tumor biopsies or resection samples, if available. 
Change in CD8+ T cells before and after treatment will be evaluated and compared 
using paired T-test by treatment. If the expression levels are not normally distributed, 
non-parametric methods such as the Wilcoxon Signed Rank test will be used. The 
change in CD8+ T cells will also be compared by treatment using the two-sample 
T-test. 
Immune subtypes: 
Immune subtypes within the tumor with neoadjuvant atezolizumab vs atezolizumab + 
PEGPH20 or other combinations at the time of surgery will be reported using means and 
standard deviations by treatment group and will be compared using a two-sample T-test. 
In addition, if adequate tissue sample is available, the change in immune subtypes before 
and after treatment will be evaluated and compared using paired T-test by treatment 
group. If the expression levels are not normally distributed, non-parametric methods 
such as the Wilcoxon Signed Rank test will be used.

19.8 
ADVERSE EVENT REPORTING 
Sponsor Reporting: Notifying participating investigators at affiliate sites of 
adverse events 
It is the responsibility of the study Sponsor to notify all affiliate sites, in a written IND safety 
report, of any adverse event associated with the use of the drug that is both serious 
and unexpected, as well as any finding from tests in laboratory animals that suggest 
a significant risk for human patients. Additionally, Sponsors are also required to 
identify in IND safety reports all previous reports concerning similar adverse events 
and to analyze the significance of the current event in light of the previous reports. 
Sub-Site Serious Adverse Event Reporting Procedures: 
Each participating investigator is required to abide by the reporting requirements set by 
Columbia University Medical Center. The study must be conducted in compliance with 
FDA regulations, local safety reporting requirements, and reporting requirements of the 
PI. 
Participating investigators must report each serious adverse event to the Columbia 
University Medical Center Overall PI within 24 hours of learning of the occurrence using 
the SAE Report Form. In the event that the participating investigator does not become 
aware of the serious adverse event immediately (e.g., participant sought treatment 
elsewhere), the participating investigator is to report the event within 24 hours after 
learning of it and document the time of his or her first awareness of the adverse event. 
Report serious adverse events by telephone, email, or facsimile to:

The participating investigator must provide follow-up information on the serious adverse 
event until resolution of the event. Follow-up information should describe whether the 
event has resolved or continues, if and how the event was treated, and whether the 
participant will continue or discontinue study participation.  
Follow-up information is sent to the same person to whom the original SAE Report Form 
was sent, using a new SAE Report Form stating that this is a follow-up to the previously 
reported SAE and giving the date of the original report. Each re-occurrence, 
complication, or progression of the original event should be reported as a follow-up to 
that event regardless of when it occurs. The follow-up information should describe 
whether the event has resolved or continues, if and how it was treated, and whether 
the patient FRQWLQXHGor withdrew from study participation or if study drug was 
interrupted or discontinued. 
If the SAE is not previously documented in the Investigator s Brochure for the study 
drug (new occurrence) and is thought to be related to the investigational agent, the 
Sponsor-Investigator may urgently require further information from the investigator for 
reporting to Health Authorities.

Each affiliate site will be assigned a site number. Each patient that signs consent should 
be assigned a unique code number consisting of site number followed by a number with 
each new patient being assigned the next sequential number (e.g., 04-10). All sites will 
be required to enter their data in the Velos eResearch, the Clinical Trial Management 
System used for all Cancer- related clinical research at CUMC. All users must login with 
their own application username and password. Users off campus must first access the 
Virtual Private Network with their assigned campus username and password and then 
use their application credentials. 
Patient confidentiality must be maintained according to HIPAA regulations and 
GCP recommendations. Except when required by law, study information shared with 
persons and organizations outside of CUMC must not identify the patient by name, 
social security number, address, telephone number, or any other direct personal

Appendix 2 
Adverse Events and Management Guidelines for Atezolizumab 
Toxicities associated or possibly associated with atezolizumab treatment should be 
managed according to standard medical practice. Additional tests, such as autoimmune 
serology or biopsies, should be used to evaluate for a possible immunogenic etiology. 
Although most immune-related adverse events observed with immunomodulatory agents 
have been mild and self-limiting, such events should be recognized early and treated 
promptly to avoid potential major complications. Discontinuation of atezolizumab may 
not have an immediate therapeutic effect, and in severe cases, immune-related toxicities 
may require acute management with topical corticosteroids, systemic corticosteroids, or 
other immunosuppressive agents.  
The investigator should consider the benefitrisk balance a given patient may be 
experiencing prior to further administration of atezolizumab. In patients who have met 
the criteria for permanent discontinuation, resumption of atezolizumab may be 
considered if the patient is deriving benefit and has fully recovered from the 
immune-related event. Patients can be re-challenged with atezolizumab only after 
approval has been documented by the investigator (or an appropriate delegate) from the 
study Principal Investigator.  
MANAGEMENT GUIDELINES 
PULMONARY EVENTS 
Dyspnea, cough, fatigue, hypoxia, pneumonitis, and pulmonary infiltrates have been 
associated with the administration of atezolizumab. Patients will be assessed for 
pulmonary signs and symptoms throughout the study and will have computed 
tomography (CT) scans of the chest performed at every tumor assessment.   
All pulmonary events should be thoroughly evaluated for other commonly reported 
etiologies such as pneumonia or other infection, lymphangitic carcinomatosis, pulmonary 
embolism, heart failure, chronic obstructive pulmonary disease, or pulmonary 
hypertension. Management guidelines for pulmonary events are provided in Table 1.

HEPATIC EVENTS 
Immune-related hepatitis has been associated with the administration of atezolizumab. 
Eligible patients must have adequate liver function, as manifested by measurements of 
total bilirubin and hepatic transaminases, and liver function will be monitored throughout 
study treatment. Management guidelines for hepatic events are provided in Table 2. 
Patients with right upper-quadrant abdominal pain and/or unexplained nausea or 
vomiting should have liver function tests (LFTs) performed immediately and reviewed 
before administration of the next dose of study drug. 
For patients with elevated LFTs, concurrent medication, viral hepatitis, and toxic or 
neoplastic etiologies should be considered and addressed, as appropriate.

ENDOCRINE EVENTS 
Thyroid disorders, adrenal insufficiency, diabetes mellitus, and pituitary disorders have 
been associated with the administration of atezolizumab. Management guidelines for 
endocrine events are provided in Table 4. 
Patients with unexplained symptoms such as headache, fatigue, myalgias, impotence, 
constipation, or mental status changes should be investigated for the presence of 
thyroid, pituitary, or adrenal endocrinopathies. The patient should be referred to an 
endocrinologist if an endocrinopathy is suspected. Thyroid-stimulating hormone (TSH) 
and free triiodothyronine and thyroxine levels should be measured to determine whether 
thyroid abnormalities are present. Pituitary hormone levels and function tests (e.g., TSH, 
growth hormone, luteinizing hormone, follicle-stimulating hormone, testosterone, 
prolactin, adrenocorticotropic hormone [ACTH] levels, and ACTH stimulation test) and

IMMUNE-RELATED MYOCARDITIS 
Immune-related myocarditis has been associated with the administration of 
atezolizumab. Immune-related myocarditis should be suspected in any patient 
presenting with signs or symptoms suggestive of myocarditis, including, but not limited 
to, dyspnea, chest pain, palpitations, fatigue, decreased exercise tolerance, or syncope. 
Immune-related myocarditis needs to be distinguished from myocarditis resulting from 
infection (commonly viral, e.g., in a patient who reports a recent history of 
gastrointestinal illness), ischemic events, underlying arrhythmias, exacerbation of 
preexisting cardiac conditions, or progression of malignancy.   
All patients with possible myocarditis should be urgently evaluated by performing cardiac 
enzyme assessment, an ECG, a chest X-ray, an echocardiogram, and a cardiac MRI as 
appropriate per institutional guidelines. A cardiologist should be consulted. An 
endomyocardial biopsy may be considered to enable a definitive diagnosis and 
appropriate treatment, if clinically indicated. 
Patients with signs and symptoms of myocarditis, in the absence of an identified 
alternate etiology, should be treated according to the guidelines in Table 6.

INFUSION-RELATED REACTIONS 
No premedication is indicated for the administration of Cycle 1 of atezolizumab. 
However, patients who experience an IRR with Cycle 1 of atezolizumab may receive 
premedication with antihistamines or antipyretics/analgesics (e.g., acetaminophen) for 
subsequent infusions. Metamizole (dipyrone) is prohibited in treating atezolizumab-
associated IRRs because of its potential for causing agranulocytosis. 
Guidelines for medical management of IRRs during Cycle 1 are provided in Table 7. For 
subsequent cycles, IRRs should be managed according to institutional guidelines.

IMMUNE-RELATED MENINGOENCEPHALITIS 
Immune-related meningoencephalitis is an identified risk associated with the 
administration of atezolizumab. Immune-related meningoencephalitis should be 
suspected in any patient presenting with signs or symptoms suggestive of meningitis or 
encephalitis, including, but not limited to, headache, neck pain, confusion, seizure, motor 
or sensory dysfunction, and altered or depressed level of consciousness. 
Encephalopathy from metabolic or electrolyte imbalances needs to be distinguished from 
potential meningoencephalitis resulting from infection (bacterial, viral, or fungal) or 
progression of malignancy, or secondary to a paraneoplastic process.   
All patients being considered for meningoencephalitis should be urgently evaluated with 
a CT scan and/or MRI scan of the brain to evaluate for metastasis, inflammation, or 
edema. If deemed safe by the treating physician, a lumbar puncture should be 
performed and a neurologist should be consulted. 
Patients with signs and symptoms of meningoencephalitis, in the absence of an 
identified alternate etiology, should be treated according to the guidelines in Table 11.

RENAL EVENTS 
Immune-related nephritis has been associated with the administration of atezolizumab. 
Eligible patients must have adequate renal function, and renal function, including serum 
creatinine, should be monitored throughout study treatment. Patients with abnormal 
renal function should be evaluated and treated for other more common etiologies 
(including prerenal and postrenal causes, and concomitant medications such as 
non-steroidal anti-inflammatory drugs). Refer the patient to a renal specialist if clinically 
indicated. A renal biopsy may be required to enable a definitive diagnosis and 
appropriate treatment. 
Patients with signs and symptoms of nephritis, in the absence of an identified alternate 
etiology, should be treated according to the guidelines in Table 12.

IMMUNE-RELATED MYOSITIS 
Immune-related myositis has been associated with the administration of atezolizumab.  
Myositis or inflammatory myopathies are a group of disorders sharing the common 
feature of inflammatory muscle injury; dermatomyositis and polymyositis are among the 
most common disorders.  Initial diagnosis is based on clinical (muscle weakness, muscle 
pain, skin rash in dermatomyositis), biochemical (serum creatine kinase increase), and 
imaging (electromyography/MRI) features, and is confirmed with a muscle biopsy. 
Patients with signs and symptoms of myositis, in the absence of an identified alternate 
etiology, should be treated according to the guidelines in Table 13.

SYSTEMIC IMMUNE ACTIVATION 
Systemic immune activation is a rare condition characterized by an excessive immune 
response. Given the mechanism of action of atezolizumab, systemic immune activation 
is considered a potential risk for atezolizumab. 
Recommendations regarding early identification and management of systemic immune 
activation are provided below. In the event of suspected systemic immune activation, 
atezolizumab should be withheld. 
Early disease recognition is critical, and systemic immune activation should be 
suspected if, in the absence of an alternative etiology, the patient meets two or more of 
the following criteria: 
 
Hypotension that is refractory to aggressive IV fluid challenge 
Vasopressor support may be required. 
 
Respiratory distress that requires aggressive supportive care 
Supplemental oxygen and intubation may be required. 
 
Fever  38.5C 
 
Acute renal or hepatic failure 
 
Bleeding from coagulopathy 
 
Any of the following unexplained laboratory abnormalities (change from baseline):  
cytopenias (in two or more lineages), significant transaminitis, or coagulopathy 
 
For patients with suspected systemic immune activation, an initial evaluation should 
include the following: 
 
CBC with peripheral smear 
 
PT, PTT, fibrinogen, and D-dimer 
 
Ferritin 
 
Soluble interleukin 2 (IL-2) receptor (soluble CD25) 
 
Triglycerides 
 
AST, ALT, and direct bilirubin 
 
LDH 
 
Complete neurologic and abdominal examination (assess for hepatosplenomegaly) 
 

Appendix 2: Risks Associated with Atezolizumab and Guidelines for Management of 
Adverse Events Associated with Atezolizumab 
  
162 
 
Laboratory tests with normal results should be repeated frequently in patients for whom 
a high clinical suspicion of systemic immune activation exists. 
If neurologic abnormalities are present, consider cerebrospinal fluid analysis and/or an 
MRI of the brain. 
If cytopenias are present (Grade  2 in two or more lineages) or ferritin is  3000 ng/mL, 
the following evaluations should also be performed:   
 
Bone marrow biopsy and aspirate (assess for evidence of hemophagocytosis) 
 
Adenovirus, cytomegalovirus, Epstein-Barr virus, herpes-simplex virus, and human 
herpesvirus 6, 7, and 8 evaluations (for reactivated or active disease) 
 
Diagnostic criteria and recommended management for systemic immune activation are 
provided in Table 14. The diagnostic criteria apply only when alternative etiologies have 
been excluded.
