Background and Rationale 
1.2.1 Pancreas cancer 
Pancreas cancer is a life-threatening disease. AACR estimates deaths due to pancreas cancer to 
rank 2nd among all cancer-related deaths in the U.S. by 2030 [1]3DQFUHDVFDQFHULVLQRI
cases diagnosed in the later stages of its progression (stage III and IV), resulting in poor prognosis 
with a median survival of 6 to 9 months from symptom onset and less than 6 months from diagnosis 
(Figure 1).[2]

Figure 1 Percent patients at different AJCC stages at time of initial diagnosis of pancreas cancer (per 
7th edition of American Joint Committee on Cancer, AJCC; left) of more than 6,000 pancreas cancer 
patients presenting between 2000 and 2005 to Memorial Sloan-Kettering Cancer Center, NY, and 
their corresponding 5-year survival rates (right) from MSKCC Pancreatic Cancer Registry. 
There is no standardized second-line therapy in pancreas cancer. FDA has approved 5-FU-based 
(FOLFIRINOX) and gemcitabine-based (gemcitabine + DEUD[DQH [nab-SDFOLWD[HO@) regimens for 
1st line therapy, but there is no evidence of clinical efficacy of the currently empirically chosen 2nd 
line regimens in randomized studies.[3, 4] )2/),5,12; D WR[LF WULSOHW FRPELQDWLRQ RI

L1 inhibition and gemcitabine in pancreas cancer 
Combination immunotherapy approaches are a promising new therapeutic strategy in pancreas and 
are currently under active investigation. In pancreatic cancer, one of the most clinically advanced 
combination immunotherapy strategies is combination vaccines in combination with metronomic 
cisplatin, given as an immunomodulator (as gemcitabine in combination with M7824 in this study) 
(Le DT). In a prespecified per-protocol analysis of patients who received at least three doses (two

FOLFIRINOX combination therapy versus gemcitabine. Enhanced mesothelin-specific CD8 T-
cell responses were associated with longer OS, regardless of treatment arm. Preclinically, a large

1.2.6 Preclinical rationale using M7824 in combination with gemcitabine 
The inability to confidently administer M7824 for prolonged periods of time (beyond 10 – 14 days) 
due to the development of allogeneic immune responses against human sequences of M7824 has 
been a limiting factor in small animal studies with M7824. However, the following 3 preclinical

Reduction of primary tumor weight in the murine C57B/L Panc02 model: 
The C57B/L Panc02 model is a syngeneic orthotopic injection model of pancreas cancer inducing 
pancreatic tumors through the injection of KRAS-mutant murine Panc02 into the pancreas of 
immunocompetent C57B/L6 wild type mice. These tumors are populated by immune cell 
populations from the host as they grow. While main immune population like tumor-associated 
macrophages, MDSCs, and T-regs have been identified in the later stages of Panc02 tumors, there 
are differences to the immune landscape of autochthonous murine models of pancreas cancer or 
human pancreatic cytoarchitecture.

M7824, given on day 3, 5, and 7, in combination with gemcitabine reduced primary pancreatic 
tumor weight in this model with, in this model, no further cooperative effect on reduction of tumor 
growth compared to M7824 alone (Figure 11). 
 
Figure 11 M7824 in addition to gemcitabine reduces weights of Panc02 tumors (left). Animals were 
administered 3 doses of M7824 and 1 dose of gemcitabine (as indicated in table) and were harvested 
28 days after start of treatment.

sarcomatoid histology of Panc02 tumors is considerably different from KP16 or KPC tumors, or 
human pancreas cancer specimens.  
To assess cooperativity between M7824 and gemcitabine in a cancer model with an approved 
standard of care gemcitabine and with a greater epithelial tumor component than in the Panc02 
model, M7824 and gemcitabine were also tested in the C57B/L6 MB49 preclinical bladder cancer

localized radiotherapy, a highly synergistic antitumor effect was achieved with only a single low

up blood, blood in their urine, or blood in the stool).  Accordingly, patients will be notified of the 
same possible risk in the informed consent document for this study. 
1.2.10 Rationale for the Clinical Trial 
The administration of M7824 in combination with gemcitabine to subjects with advanced 
pancreatic tumors who have progressed on 1st-line systemic chemotherapy is justified by the 
following:

x Pancreatic tumor weights are further reduced by the addition of gemcitabine compared to 
M7824 therapy alone in the syngeneic Panc02 pancreatic cancer mouse model 
x M7824 either in combination with gemcitabine, or in combination with other systemic 
chemotherapy agents, additively reduces tumor growth compared to respective monotherapies

the following two safety measures have been taken. The standard dose level of gemcitabine is 
1,000 mg/m2 over 30 minutes once weekly for the first 7 weeks, then one week rest, then once

Over the past decade there has been increased efforts to bring advances in pharmacogenomics to

The empirical formula for gemcitabine HCl is C9H11F2N3O4 • HCl. It has a molecular weight of

combination of two actions of the diphosphate and the triphosphate nucleosides, which leads to 
inhibition of DNA synthesis. First, gemcitabine diphosphate inhibits ribonucleotide reductase, 
which is responsible for catalyzing the reactions that generate the GHR[\QXFOHRVLGH triphosphates 
for DNA synthesis. Inhibition of this enzyme by the diphosphate nucleoside causes a reduction in

competes with dCTP for incorporation into DNA. The reduction in the intracellular concentration 
of dCTP (by the action of the diphosphate) enhances the incorporation of gemcitabine triphosphate 
into DNA (self-potentiation). After the gemcitabine nucleotide is incorporated into DNA, only one 
additional nucleotide is added to the growing DNA strands. After this addition, there is inhibition 
of further DNA synthesis. DNA polymerase epsilon is unable to remove the gemcitabine 
nucleotide and repair the growing DNA strands (masked chain termination).

varied from 500 to 3,600 mg/m2. Gemcitabine pharmacokinetics are linear and are described by 
a 2-compartment model. Population pharmacokinetic analyses of combined single and multiple 
dose studies showed that the volume of distribution of gemcitabine was significantly influenced 
by duration of infusion and gender. Clearance was affected by age and gender. Differences in 
either clearance or volume of distribution based on patient characteristics or the duration of 
infusion result in changes in half-life and plasma concentrations. Table 3 shows plasma clearance 
and half-life of gemcitabine following short infusions for typical patients by age and gender. 
Gemcitabine half-life for short infusions ranged from 32 to 94 minutes, and the value for long 
infusions varied from 245 to 638 minutes, depending on age and gender, reflecting a greatly 
increased volume of distribution with longer infusions. The lower clearance in women and the 
elderly results in higher concentrations of gemcitabine for any given dose. The volume of 
distribution was increased with infusion length. Volume of distribution of gemcitabine was 50 
L/m2 following infusions lasting <70 minutes, indicating that gemcitabine, after short infusions,

Data from 2 clinical trials evaluated the use of Gemzar in patients with locally advanced or 
metastatic pancreatic cancer.[13, 29] The first trial compared Gemzar to 5-Fluorouracil (5-FU) in 
patients who had received no prior chemotherapy. A second trial studied the use of Gemzar in 
pancreatic cancer patients previously treated with 5-FU or a 5-FU-containing regimen. In both 
studies, the first cycle of Gemzar was administered intravenously at a dose of 1,000 mg/m2 over

by a week of rest from treatment with Gemzar. Subsequent cycles consisted of injections once 
weekly for 3 consecutive weeks out of every 4 weeks. The primary efficacy parameter in these 
studies was “clinical benefit response,” which is a measure of clinical improvement based on 
analgesic consumption, pain intensity, performance status, and weight change. Definitions for 
improvement in these variables were formulated prospectively during the design of the 2 trials. A 
patient was considered a clinical benefit responder if either:

dose of 600 mg/m2 for 30 minutes. The results from this randomized trial are shown in 
Table 4. Patients treated with Gemzar had statistically significant increases in clinical 
benefit response, survival, and time to disease progression compared to 5-FU.[13] The 
Kaplan-Meier curve for survival is shown in Figure 17. No confirmed objective tumor

course will allow detection of lack of M7824 activity and can trigger additional investigations 
(ADA development) into lack of efficacy. 
1.2.17.4 ADA 
Anti-Drug Antibody development is an accepted mechanism of loss of efficacy administered 
human monoclonal antibodies. Measuring titers will ensure that lack of efficacy of M7824 is not 
due to ADA development. 
1.2.17.5 Evaluate the intratumoral immunogenicity of M7824 in combination with gemcitabine 
on pre- and on-treatment biopsies: 
3UHFOLQLFDO VWXGLHV VKRZ WKDW 7*)ȕ inhibition and gemcitabine cooperate immunologically to 
induce anti-tumor responses reducing immune evasive cues of the intratumoral immune milieu and 
enhancing T cell-mediated anti-tumor responses. The flow cytometry studies on pre- and on-
treatment tumor biopsies aim to (1) investigate immunogenic cooperativity of M7824 in 
combination with gemcitabine in human tumors, (2) identify an immunologic landscape likely to 
response to the pursued combination approach, and (3) aid to develop longitudinal predictive 
biomarkers for later improved patient selection (correlation with immune cell changes pre- and 
on-treatment and clinical outcome). 
1.2.17.6 Rationale for circulating free tumor DNA measures: 
Measures of copies of genomic tumor DNA released into the circulation has been shown to be an 
accurate measure of tumor burden in patients with solid organ cancers and to have value to follow 
response to anti-cancer treatment both for the early identification of responders as well as patients 
to recur after remission. Including longitudinal measurements from baseline and on-treatment of

doses increased to the standard 1,000 mg/m2 level. 
1.2.18 Amendment B 
With this amendment we want to update DLT definition. Originally, we inadvertently left out DLT 
definitions DQGGLGQRWH[FOXGHDGYHUVHHYHQWVZLWKFOHDUHYLGHQFHRIDQDOWHUQDWLYHFDXVDOLW\RU
H[SHFWHGDQGVKRUWO\UHVROYHG 
As a result, there were DLTs, that in the opinion of the PI, are not related to study treatment or

we have 2 DLTs and per protocol need to go to lower dose of study drug M7824. However, we 
are reluctant to do this, as (1) the combination treatment is generally well tolerated in the 6 patients 
on study so far, and (2) there are some early signs of clinical efficacy (no patient came off study 
yet due to progression of disease, there are 2 biochemical responses) with original dose level 0 
(1,200mg flat dose M7824) and we do not want to risk the potential benefit with lowering of 
M7824 dose unnecessarily, in particular in a disease like pancreatic cancer where drug delivery 
and drug penetration is a major issue. 
In several hundreds of patients treated with the standard 1,200mg flat dose, many of these patients 
treated at the Clinical Center, M7824 was found to have a very favorable side-effect profile nearly 
identical to approved immune checkpoint inhibitors like pembrolizumab or nivolamab. While we

also do not want to unnecessarily lower M7824 dose levels in a disease where the lack of sufficient

While we have not seen any formal PRs yet (for two patients also too early), none of the pancreas 
cancer patients treated so far have shown despite widely metastatic disease radiologic progression 
of disease (all stable disease).

therapy (which we consider consistent with the mechanism of immunotherapy). 
Dose level -1 (500 mg of M7824) potentially will deprive patients of efficacious doses in a disease 
where drug penetration and low intratumoral drug levels are a significant impediment of 
therapeutic efficacy and should only occur if the new drug combination is found not safe at the 
respective dose level. 
With this amendment we want to omit current patients from the DLT analysis and repeat the entire 
safety run-in with 6 new study subjects under the new DLT criteria.

STUDY IMPLEMENTATION 
3.1 
Study Design  
This is an open label Phase IB/II trial, accruing initially one cohort to determine the safety and 
recommended Phase II dose (RP2D) of M7824 in combination with gemcitabine (Phase IBDQG
WRH[DPLQHWKHVDIHW\DQGefficacy of the M7824 in combination with gemcitabine in the following 
cohort (Phase II).  
Up to 2 dose levels of M7824 will be tested in the safety run-in cohort IB with up to 12 subjects 
enrolled. Once a recommended phase 2 dose has been determined, up to 20 subjects will be 
evaluated at that dose level in the Phase II cohort, inclusive of those patients treated at the RP2D 
during the safety run-in. 
Patients will receive treatment in cycles consisting of 14 (+/- 3) days.  
Administration of M7824 will be every 2 weeks by IV infusion starting on day 1 of cycle 1. The 
starting M7824 dose is 1,200 mg. 
Gemcitabine will be administered IV once a week starting on day 1 of cycle 2 for 4 weeks (cycles 
2-3). Then, once weekly for 3 weeks with one week without gemcitabine starting on day 1 of cycle 
4 (cycles 4-13).  
Gemcitabine will be discontinued after 6 months of total gemcitabine therapy. 
After gemcitabine discontinuation, treatment with M7824 will continue until patient meets off 
treatment criteria (Section 3.8.1).  
In all patients, gemcitabine dosage will be adjusted according to DMET genotyping and risk

Patients with low risk will be assigned to standard dosage of 1,000 mg/m2 per dose. 
Patients with high risk will be started on 600 mg/m2 per dose for first 4 doses of gemcitabine. After 
4 doses of gemcitabine, patients in this category will continue on 600 mg/m2 per dose or standard 
1,000 mg/m2 per dose (see Section 3.3.2).

Intra-patient M7824 dose de-escalation is not permitted for subjects enrolled in the safety run-in 
cohort. Subject enrolled onto safety run-in cohorts who have either had a DLT or completed the 
DLT evaluation period will be part of the DLT evaluation of the respective phase I dose level. 
3.1.2.2 Gemcitabine  
During Phase I portion of this trial, gemcitabine starting dose levels will be adjusted according to 
results of polymorphism testing of the CDA gene using the DMET platform of the Clinical 
Pharmacology Program (as per NCI 16-C-0076) (See Section 3.3.2).  
If patients develop side effects related to gemcitabine, dose modifications according to label are 
recommended:

For patients receiving 600 mg/m2 gemcitabine per dose gemcitabine dosage will not be reduced 
and gemcitabine will be withheld. 
3.1.3 Phase II Cohort 
The efficacy part of the study will be conducted with the M7824 dose level found to be safe in 
combination with gemcitabine during phase IB. Once a recommended phase 2 dose of M7824 has 
been determined, up to 20 subjects will be evaluated at that dose level, inclusive of those patients 
treated at the RP2D during the safety run-in. 
Enrollment into phase II part of the study can commence after DLT period of 6th subject of 
respective DLT cohort is complete.  
Gemcitabine dosage will be assigned per Section 3.3.2   
During first stage of Phase II 13 patients will be enrolled. If 0 of 13 patients respond, then no 
further patients will be enrolled. If 1 or more of the first 13 evaluable patients enrolled have a 
response (PR or CR), then during second stage accrual will continue until a total of 20 evaluable 
patients have been enrolled. Since it may take several weeks for a response to be identified, a pause 
in the accrual of 6 weeks will be made before accruing to the second stage.

Drug Administration 
3.3.1 M7824. 
M7824 will be administered as a 1-hour (-10 minutes / +20 minutes) IV infusion on Day 1 of each 
cycle (14 days) before gemcitabine.  
M7824 is administered as an intravenous (IV) infusion via a peripheral OR central vascular access 
device (VAD). Confirm patient has a titanium port before accessing the Central VAD. A 0.2-
micron polyethersulfone (PES) in-line filter is mandatory for administration. 
In order to mitigate potential infusion-related reactions, premedication with an antihistamine and

Patients must be observed for 2 hours after the first M7824 dose. If no reactions are observed, the 
patients need to be monitored for only 30 minutes after subsequent doses.  
If an allergic reaction occurs, the subject must be treated according to the best available medical 
practice. Please see the guidelines for handling of infusion-related reaction in Table 6.  
Investigators should also monitor subjects closely for potential irAEs, which may become manifest 
after several weeks of treatment. Such events may consist of persistent rash, diarrhea and colitis, 
autoimmune hepatitis, arthritis, glomerulonephritis, cardiomyopathy, or uveitis and other 
inflammatory eye conditions.  
For vital signs measurements see Study Calendar (Section 3.7).

3.5 
Assessments on Treatment  
In this trial, the treatment with M7824 will continue until patient meets off treatment criteria 
(Section 3.8.1). In the case of PD, subjects will continue treatment and have confirmatory scans 4 
weeks after the initial scan documenting PD. In case of confirmation of PD per RECIST patient 
will come off treatment.  
For subjects who achieve a PR or CR on M7824 gemcitabine combination therapy and then 
subsequently develop disease progression after stopping therapy, due to reasons other than PD (AE 
which later resolve), 1 re-initiation course of treatment at the same dose and schedule of M7824 
only is allowed at the discretion of the Investigator. Gemcitabine will not be administered again. 
The Investigator will need to confirm that the benefit of re-initiating treatment outweighs risks of 
WR[LFLWLHV involved, such as that which led to initial treatment discontinuation. In order to be 
eligible for re-WUHDWPHQWWKHVXEMHFWPXVWQRWKDYHH[SHULHQFHGDQ\WR[LFLW\WKDWOHGWRSHUPDQHQW
treatment discontinuation of the initial M7824 therapy. Prior to re-initiation of the study treatment, 
malignant disease needs to be radiologically re-staged to assess all known sites of the disease and 
to establish a new baseline for subsequent tumor measurements.  
Relevant safety laboratory samples must be drawn and results available and verified prior to 
re-initiating treatment. Patients should be reconsented at this point. Subjects who re-initiate 
treatment will stay on study and will be treated and monitored according to the Study Calendar 
3.7. During re-treatment no research procedures will be done. 
A time window of up to 3 days before or 1 day after a scheduled visit day (-3 / +1 days) will be 
permitted for all study procedures. In addition, the tumor evaluation has a tumor assessment 

Abbreviated Title: M7824/Gemcitabine for AAPC

visiting time window (repeat imaging) of 5 days prior to dosing (-5 days). Furthermore, if any 
Screening/Baseline procedures are conducted within 3 days prior to Day 1 of Cycle 1 the 
assessments scheduled on Cycle 1, Day 1 do not need to be repeated. 
3.5.1 End-of-Treatment Visit 
All subjects should undergo an End-of-Treatment visit after discontinuation of M7824 for any 
reason. This visit should be performed on the day or within 7 days after the decision to discontinue 
trial treatment but before any new antineoplastic therapy is started (if possible). If it is known to 
the Investigator at the time of the End of-Treatment visit that the subject will start new treatment 
within 28 days of last treatment or they will be unable to return within 28 days of last treatment, 
assessments associated with the 28-Day Safety Follow-up visit may be conducted at the End-of-
Treatment visit. The discontinuation visit consists of assessments indicated in Study Calendar, 
Section 3.7. 
3.5.2 Post-Treatment Follow-up 
3.5.2.1 28-Day Safety Follow-up Visit 
A Safety Follow-up visit is scheduled 4 weeks (28 ± 5 days) after the last administration of M7824 
but before any new therapy is started, if possible, whichever occurs earlier. The 28-Day Safety 
Follow-up visit will comprise a full assessment for safety, immunogenicity, and tumor response 
as appropriate, which will include assessments indicated in Study Calendar, Section 3.7.  
3.5.2.2 Long-term Follow-up  
All SAEs ongoing at the 28-Day Safety Follow-up visit must be monitored and followed up by the 
Investigator until stabilization or until the outcome is known, unless the subject is documented as 
“lost to follow-up.” In addition, all trial drug-related SAEs occurring after 28-Day Safety 
Follow-up visit and ongoing at the Safety Follow-up visit have to be followed up in the same 
manner.  
Subjects without PD at the 28-Day Safety Follow-up visit will be followed till disease progression 
(CT / MRI scans every 12 weeks with the first assessment 12 weeks after the previous tumor 
assessment until PD).  
Subjects with PD after the 28-Day Safety Follow-up visit, will be followed quarterly (± 14 days) 
for survival (including assessment of any further anticancer therapy) by phone call or e-mail for 
1 year. Survival follow up will continue every 6 months after that.

procedures are conducted within 3 days prior to Day 1 of Cycle 1, the assessments scheduled on Day 1 of Cycle 1 do not need to be 
repeated. 
2 M7824 will be administered as a 1 hour (-10 minutes / +20 minutes) IV infusion on Day 1 of each cycle before gemcitabine when both 
drugs are given on the same day.  
3 Gemcitabine will be given starting on Day 1 of Cycle 2 at assigned dose over 30 (+/- 10) minutes once weekly for the 4 weeks (cycles 
2-3)). Starting on Cycle 4 once weekly for 3 weeks with one week without gemcitabine. Gemcitabine will be discontinued after Cycle 
13 (after a total of 6 months of gemcitabine therapy). 
4 As indicated in section 10.3, all subjects will be offered the opportunity to complete an NIH advanced directives form. This should be 
done preferably at baseline but can be done at any time during the study as long as the capacity to do so is retained. The completion of 
the form is strongly recommended, but is not required

19 All SAEs ongoing at the 28-Day Safety Follow-up visit must be monitored and followed up by the Investigator until stabilization or 
until the outcome is known, unless the subject is documented as “lost to follow-up.” In addition, all trial drug-related SAEs occurring 
after 28 Day Safety Follow up visit and ongoing at the Safety Follow-up visit should be followed up in the same manner. 
20 If subjects are unable or not willing to come to NIH after treatment discontinuation for FU visits, they will be followed quarterly (± 
14 days) by phone call or e-mail for survival, adverse events and further tumor therapy 
21 At baseline, cycles 2, 4, 10 and EOT visit. Patients who have heart pacemakers, metal implants, or metal chips or clips in or around 
the eyeballs cannot be scanned with an MRI because of the risk that the magnet may move the metal in these areas. DCE-MRI in cycle 
2 should be obtained before first gemcitabine infusion, DCE-MRI at baseline and in cycles 2, 4 and 10 are mandatory, at EOT visit it is 
per PI discretion. If DCE-MRI is not obtained in cycle 2, it may be obtained in cycle 3, with the following DCE-MRI studies moving to 
cycle 5 and 11. 
22 Prior to study treatment, patients (under NCI 16-C-0076) will provide one peripheral blood sample to analyze genomic DNA via the

Plasma M7824 PK measurements will be done at EMD Serono 
5.1.3.2 Gemcitabine Pharmacokinetics (Figg Lab) 
Blood samples for the determination of gemcitabine (GEM) plasma levels will be obtained from 
participating patients via 4 mL sodium heparin (green top) tube (BD, Franklin Lakes, NJ) collected 
according to Study Calendar 3.7. Bioanalytical measurements will be conducted on an ultra HPLC-
MS/MS system by the Clinical Pharmacology Program (CPP).  
Because GEM is rapidly deactivated by cytidine deaminase (CD), green top tubes will be fortified 
with 100 uM tetrahydrouridine (THU). These tubes will be prepared in advance by the CPP and 
provided to the clinic. In advance of PK samples being drawn, please notify the CPP at least 24 
hrs. prior to prepare fresh green top tubes with 100 uM THU. 
This data will be used to monitor GEM plasma concentrations to assess any drug interactions with 
M7834 and/or correlations with pharmacogenomics, adverse events, and clinical response.

Sample bar-codes are linked to patient demographics and limited clinical information. This 
information will only be provided to investigators listed on this protocol, via registered use of the 
LABrador. It is critical that the sample remains linked to patient information such as race, age, 
dates of diagnosis and death, and histological information about the tumor, in order to correlate 
genotype with these variables.

DATA COLLECTION AND EVALUATION  
6.1 
Data Collection 
The PI will be responsible for overseeing entry of data into an in-house password protected 
electronic system (C3D) and ensuring data accuracy, consistency and timeliness. The principal 
investigator, associate investigators/research nurses and/or data manager will assist with the data 
management efforts. All data obtained during the conduct of the protocol will be kept in secure 
network drives or in approved alternative sites that comply with NIH security standards. Primary 
and final analyzed data will have identifiers so that research data can be attributed to an individual 
human subject participant.  
All adverse events, including clinically significant abnormal findings on laboratory evaluations, 
regardless of severity, will be followed until return to baseline or stabilization of event. Patients 
will be followed for adverse events for 28 days after removal from study treatment or until off-
study, whichever comes first.  
An abnormal laboratory value will be recorded in the database as an AE only if the laboratory 
abnormality is characterized by any of the following: 
x 
Results in discontinuation from the study 
x 
Is associated with clinical signs or symptoms  
x 
Requires treatment or any other therapeutic intervention 
x 
Is associated with death or another serious adverse event, including hospitalization.

following initial documentation of objective response. For subjects continuing treatment beyond 
12 months tumor evaluations should take place every 12 weeks 

Abbreviated Title: M7824/Gemcitabine for AAPC 
Version date: 03/20/2019 
84 
 
Response and progression will be evaluated in this study using the new international criteria 
proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline 
(version 1.1) [[36, 37]] and Modified Immune-related response criteria (Section 6.4). Changes in 
the largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter 
in the case of malignant lymph nodes are used in the RECIST criteria.  
6.3.1 Disease Parameters 
Measurable disease: Measurable lesions are defined as those that can be accurately measured in at 
least one dimension (longest diameter to be recorded) as:  
•

All tumor measurements must be recorded in millimeters (or decimal fractions of centimeters). 
Malignant lymph nodes. To be considered pathologically enlarged and measurable, a lymph node 
must be >PPLQVKRUWD[LVZKHQDVVHVVHGE\&7VFDQ&7VFDQVOLFHWKLFNQHVVUHFRPPHQGHG

and followed. 
Non-measurable disease. All other lesions (or sites of disease), including small lesions (longest 
diameter <10 mm or SDWKRORJLFDOO\PSKQRGHVZLWKWRPPVKRUWD[LVDUHconsidered 
non-measurable disease. Bone lesions, leptomeningeal disease, ascites, pleural/pericardial 
effusions, lymphangitis cutis/pulmonitis, inflammatory breast disease, and abdominal masses (not 
followed by CT or MRI), are considered as non-measurable. 
Note: Cystic lesions that meet the criteria for radiographically defined simple cysts should not be 
considered as malignant lesions (neither measurable nor non-measurable) since they are, by 
definition, simple cysts. 
µ&\VWLFOHVLRQV¶WKRXJKWWRUHSUHVHQWcystic metastases can be considered as measurable lesions, if 
they meet the definition of measurability described above. However, if non-cystic lesions are 
present in the same patient, these are preferred for selection as target lesions.

total, representative of all involved organs, should be identified as target lesions and recorded and 
measured at baseline. Target lesions should be selected on the basis of their size (lesions with the 
longest diameter), be representative of all involved organs, but in addition should be those that 
lend themselves to reproducible repeated measurements. It may be the case that, on occasion, the 
largest lesion does not lend itself WRUHSURGXFLEOHPHDVXUHPHQWLQZKLFKFLUFXPVWDQFHWKHQH[W

and reported as the baseline sum diameters. If lymph nodes are to be included in the sum, then 
RQO\WKHVKRUWD[LVLVDGGHGLQWRWKHVXP The baseline sum diameters will be used as reference to 
further characterize any objective tumor regression in the measurable dimension of the disease.

Non-target lesions. All other lesions (or sites of disease) including any measurable lesions over 
and above the 5 target lesions should be identified as non-target lesions and should also be 
recorded at baseline. Measurements of these lesions are not required, but the presence, absence, or 
in rare cases unequivocal progression of each should be noted throughout follow-up.  
6.3.2 Methods for Evaluation of Measurable Disease 
All measurements should be taken and recorded in metric notation using a ruler or calipers. All 
baseline evaluations should be performed as closely as possible to the beginning of treatment and 
never more than 4 weeks before the beginning of the treatment. 
The same method of assessment and the same technique should be used to characterize each 
identified and reported lesion at baseline and during follow-up. Imaging-based evaluation is 
SUHIHUUHG WR HYDOXDWLRQ E\ FOLQLFDO H[DPLQDWLRQ XQOHVV WKH OHVLRQV EHLQJ IROORZHG FDQQRW EH
imaged but are assessable by clinicaOH[DP 
Clinical lesions: Clinical lesions will only be considered measurable when they are superficial 
(e.g., skin nodules and palpable lymph nodes) and t10 mm diameter as assessed using calipers 
(e.g., skin nodules). In the case of skin lesions, documentation by color photography, including a 
ruler to estimate the size of the lesion, is recommended.  
&KHVW[-ray: /HVLRQVRQFKHVW[-ray are acceptable as measurable lesions when they are clearly 
defined and surrounded by aerated lung. However, CT is preferable.  
Conventional CT and MRI: This guideline has defined measurability of lesions on CT scan based 
on the assumption that CT slice thickness is 5 mm or less. If CT scans have slice thickness greater 
than 5 mm, the minimum size for a measurable lesion should be twice the slice thickness. MRI is 
also acceptable in certain situations (e.g. for body scans).  
8VHRI05,UHPDLQVDFRPSOH[LVVXH 05,KDVH[FHOOHQWFRQWUDVWVSDWLDODQGWHPSRUDOUHVROXWLRQ
however, there are many image acquisition variables involved in MRI, which greatly impact image 
quality, lesion conspicuity, and measurement. Furthermore, the availability of MRI is variable 
globally. As with CT, if an MRI is performed, the technical specifications of the scanning 
sequences used should be optimized for the evaluation of the type and site of disease. Furthermore, 
as with CT, the modality used at follow-up should be the same as was used at baseline and the 
lesions should be measured/assessed on the same pulse sequence. It is beyond the scope of the 
RECIST guidelines to prescribe specific MRI pulse sequence parameters for all scanners, body 
parts, and diseases. Ideally, the same type of scanner should be used and the image acquisition 
protocol should be followed as closely as possible to prior scans. Body scans should be performed 
with breath-hold scanning techniques, if possible. 
6.3.3 Response Criteria 
All the scans performed at Baseline and other imaging performed as clinically required (other 
supportive imaging) need to be repeated at subsequent visits. In general, lesions detected at 
Baseline need to be followed using the same imaging methodology and preferably the same 
imaging equipment at subsequent tumor evaluation visits. 
Brain CT / MRI scan should be performed, if clinically indicated by development of new specific 
symptoms or on the discretion of the Principal Investigator. For each subject, the Investigator will 
designate 1 or more of the following measures of tumor status to follow for determining response: 
CT or MRI images of primary and / RUPHWDVWDWLFWXPRUPDVVHVSK\VLFDOH[DPLQDWLRQILQGLQJV

86 
 
and the results of other assessments. All available images collected during the trial period will be 
considered. The most appropriate measures to evaluate the tumor status of a subject should be 
used. The measure(s) to be chosen for sequential evaluation during the trial have to correspond to 
the measures used to document the progressive tumor status that qualifies the subject for 
enrollment. The tumor response assessment will be assessed and listed according to the Study 
Calendar 3.7. 
The foreseen treatment duration is until disease progression verified by a scan subsequent to the 
initial documentation of PDXQDFFHSWDEOHWR[LFLW\RUDQ\FULWHULRQIRUwithdrawal from the trial 
occurs (see Section 3.8). Before stopping the treatment, progressive disease should be 
confirmed by imaging 4 to 6 weeks (preferably 6 weeks, but not later) after progression has 
been diagnosed according to RECIST 1.1. If progression is based on the occurrence of a new 
lesion in an area not scanned at Baseline, a further on-study scan 6 weeks later should be 
considered before performing the 28-Day Safety Follow-up visit. Treatment may be continued 
despite progression according to RECIST 1.1 at any time if: 
x 7KHUHDUHQRQHZV\PSWRPVRUZRUVHQLQJRIH[LVWLQJV\PSWRPV 
x There is no decrease in ECOG PS. 
x The Investigator does not consider it necessary to administer a salvage therapy.  
The treatment should be stopped immediately, if the subject does not tolerate M7824 in 
combination with gemcitabine anymore or if therapeutic failure occurs, which requires urgent 
treatment with an additional drug or results in clinically significant progression / deterioration.  
Tumor responses to treatment will be assigned based on the evaluation of the response of target, 
non-target, and new lesions according to RECIST 1.1 (all measurements should be recorded in 
metric notation). 
x To assess objective response, the tumor burden at baseline will be estimated and used for 
comparison with subsequent measurements. At baseline, tumor lesions will be categorized in 
target and non-target lesions according to RECIST 1.1. 
Results for these evaluations will be recorded with as much specificity as possible so that pre- and 
post-treatment results will provide the best opportunity for evaluating tumor response.  
Any CR or PR should be confirmed according to RECIST 1.1 (Table ). In the case of a PR or 
CR, a confirmatory CT or MRI scan should be done no sooner than 4 weeks (preferably at 
the scheduled 6-week interval).  
The Investigator may perform scans in addition to a scheduled trial scan for medical reasons or if 
the Investigator suspects PD.

benefit from treatment beyond 24 months, it may be permissible.  
6.3.4 Responses 
6.3.4.1 Best overall response (BOR)  
The duration of best overall response is measured from the time measurement criteria are met for 
CR, PR or SD (whichever is first recorded) until the first date that recurrent or progressive disease 
is objectively documented (taking as reference for progressive disease the smallest measurements 
recorded since the treatment started). 
The duration of overall CR is measured from the time measurement criteria are first met for CR 
until the first date that progressive disease is objectively documented.  
6.3.4.2 Duration of stable disease  
Stable disease is measured from the start of the treatment until the criteria for progression are met, 
taking as reference the smallest measurements recorded since the treatment started, including the 
baseline measurements. Stable Disease (SD) when sum of all target lesions does not qualify for 
CR/PR/PD for Target Lesion Response and Persistence of non-target lesions on Non-Target 
Lesion Response. 
6.4 
Immune-related Response Criteria (irRECIST) 
Modified immune-related response criteria (irRECIST) will also be employed in this study. This 
new classification is based on the recent learning from clinical studies with cancer 
immunotherapies that even if some new lesions appear at the beginning of a treatment or if the 
total tumor burden does not increase substantially, tumor regressions or stabilizations might still 
occur later. For this trial, the concepts of the irRECIST are combined with RECIST 1.1. Please 
refer to Appendix C for further details. 
6.4.1 Immune-related BOR (irBOR)  
The duration of Immune-related best overall response is measured from the time measurement 
criteria are met for irCR or irPR (whichever is first recorded) until the first date that recurrent or 
progressive disease is objectively documented (taking as reference for progressive disease the 
smallest measurements recorded since the treatment started). irSD, not meeting criteria for irCR 
or irPR, in absence of irPD. 
The duration of overall irCR is measured from the time measurement criteria are first met for irCR 
until the first date that progressive disease is objectively documented. Confirmation of assessment 
might be delayed up to 12 weeks to confirm PD to account for flare.

7.3 
IND Sponsor Reporting Criteria  
From the time of the first study treatment through  the first 28 days after the subject receives the 
last investigational agent/intervention, the investigator must immediately report to the sponsor, 
using the mandatory MedWatch form 3500a or equivalent, any serious adverse event, whether or 
not considered drug related, including those listed in the protocol or investigator brochure and 
must include an assessment of whether there is a reasonable possibility that the drug caused the 
event. For events that occur more than 28 days after the last administration of investigational 
agent/intervention, only report serious adverse events that have an attribution of at least possibly 
related to the agent/intervention. 
Required timing for reporting per the above guideline: 
x Deaths H[FHSWGHDWKGXHWRSURJUHVVLYHGLVHDVHPXVWEHUHported via email within 24 
hours. A complete report must be submitted within one business day.

and perinatal conditions - Other (pregnancy)” under the Pregnancy, puerperium and perinatal 
conditions SOC.  
Congenital abnormalities or birth defects and spontaneous miscarriages should be reported and 
handled as SAEs. Elective abortions without complications should not be handled as AEs. The 
outcome of all pregnancies (spontaneous miscarriage, elective termination, ectopic pregnancy, 
normal birth, or congenital abnormality) should be followed up and documented. 
If any pregnancy occurs in the course of the study, then the investigator should inform the Sponsor 
within 1 day, i.e., immediately, but no later than 24 hours of when he or she becomes aware of 
it. 
The designated Sponsor representative will work with the investigator to ensure that all relevant 
information is provided to the Sponsor within 1 to 5 calendar days for SAEs and within 30 days 
for all other pregnancies. 
The same timelines apply when outcome information is available. 
7.3.1.2 Paternal H[SRVXUH 
Male patients should refrain from fathering a child or donating sperm during the study and for 4 
months after the last treatment with M7824 or gemcitabine whichever occurs later. Pregnancy of

STATISTICAL CONSIDERATIONS 
8.1 
 Statistical Considerations 
8.1.1 Primary efficacy endpoints 
The primary objectives of this trial are to determine the safety and tolerability, measured by 
number, severity and duration of treatment-related AEs for the combination treatment M7824 and 
gemcitabine according to CTCAE v5.0, and the occurrence, severity, and duration of Treatment-
Emergent Adverse Events (TEAEs) for the combination treatment M7824 and gemcitabine 
according to the NCI-CTCAE v5.0. and the efficacy, as measured by Best Objective Response 
(BOR) rate according to RECIST 1.1 
8.1.2 Secondary efficacy endpoints 
The secondary endpoints are the following: 
x Progression-free Survival (PFS) 
x Overall survival (OS)  
x Immune-related BOR (irBOR) using the immune-related RECIST (irRECIST)

Prior to amendment B, the protocol enrolled 6 evaluable patients into safety run-in and according 
to DLT definition, DLTs were recorded. We want to change DLT definition and the results from 
these initial 6 patients will be reported as a separate group, and accrual will begin again using the 
same phase IB design as initially proposed, but with new DLT definition described in amendment 
B. Total amount of patient on trial will be the same as with this amendment we are removing 200 
mg M7824 dose level.  
Phase IB:  
This combination will be first given to 6 patients as a safety run-in: the doses are 1,200 mg for 
M7824 and an assigned gemcitabine dose: 600 or 1,000 mg/m2 weekly according to baseline

(probability of rejecting a good agent), initially 13 evaluable patients will be enrolled into the phase 
II study, including up to 6 patients from the completed safety cohort if they are completely eligible 
for the phase II portion of the trial. If 0 of 13 patients respond, then no further patients will be 
enrolled. If 1 or more of the first 13 evaluable patients enrolled have a response (PR or CR), then 
accrual will continue until a total of 20 evaluable patients have been enrolled. Since it may take 
several weeks for a response to be identified, a pause in the accrual of 6 weeks will be made before 
accruing to the second stage. If 1 to 2 of the 20 has a clinical response, then this will be considered

Although participants who are in the phase II cohort will receive different levels of gemcitabine 
based on their genetic results, the participants will have their outcomes combined and will be 
evaluated using a single two-stage design with up to 20 participants. This will then assess the 
ability of the treatment strategy of gemcitabine (regardless of dose 600 or 1000 mg/m2) and M7824 
at a consistent dose to act together and produce responses. 
Thus, with 6 patients enrolled prior to Amendment B, up to 12 participants in the phase IB cohort 
starting with Amendment B and up to 20 evaluable participants in phase II, the trial may require 
up to 38 participants to be treated. This number may be reduced by up to 6 participants treated at 
the RP2D in the phase IB portion of the study. To allow for a small number of inevaluable patients, 
the accrual ceiling will be set at 41 participants. With an anticipated accrual rate of 10-12 patients

10.2 Participation of Children 
Individuals under the age of 18 will not be eligible to participate in this study because they are 
unlikely to have pancreatic cancerDQGEHFDXVHRIXQNQRZQWR[LFLWLHVLQSHGLDWULFSDWLHQWV 
10.3 Participation of subjects unable to give consent 
Adults XQDEOHWRJLYHFRQVHQWDUHH[FOXGHGIURPHQUROOLQJLQWKHSURWRFRO However, re-consent may 
be necessary and there is a possibility, though unlikely, that subjects could become decisionally 
impaired. For this reason and because there is a prospect of direct benefit from research participation 
(Section 10.4.2), all subjects will be offered the opportunity to direct their wishes for research and 
care to a surrogate, and assign a substitute decision maker on the “NIH Advance Directive for Health 
Care and Medical Research Participation” form so that another person can make decisions about 
their medical care in the event that they become incapacitated or cognitively impaired during the 
course of the study. Note: The PI or AI will contact the NIH Ability to Consent Assessment Team 
(ACAT) for evaluation as needed for the following: an independent assessment of whether an

procedures described in MEC Policy 87-4 and NIH HRPP SOP 14E for appointing a surrogate 
decision maker for adult subjects who are (a) decisional impaired, and (b) who do not have a legal 
guardian or durable power of attorney, will be followed.

Safety Committee. 
10.4.1.3 Risks of Dynamic Contrast Enhanced MRIs (DCE-MRI) 
This research study involves up to 5 Dynamic Contrast Enhanced MRIs (DCE-MRI) performed for 
research purposes. The main risk is allergic reaction to IV administered contrast agent. This risk is 
in the range of 1 to 1.  
10.4.1.4 Research Blood Collection Risks 
Risks of blood draws include pain and bruising in the area where the needle is placed, 
lightheadedness, and rarely, fainting. When large amounts of blood are collected, low red blood cell 
count (anemia) can develop.  
10.4.1.5 Other Risks 
Risks include the possible occurrence of any of a range of side effects which are listed in the Consent 
Document or this protocol document. Frequent monitoring for adverse effects will help to minimize 
the risks associated with administration of the study agents.

disease related DNA sequencing or disease tendencies, or misattributed paternity. Patients will be 
clearly informed that the data related to DNA sequencing and genetic analysis is coded, 
investigational and will not be shared with patients, family members or health care providers. 
Risk related to possibility that information may be released 
This includes the risk that data related to genotype, DNA sequencing or risk for disease tendency or 
trait can be released to members of the public, insurers, employers, or law enforcement agencies. 
Although there are no plans to release results to the patients, family members or health care 
providers, this risk will be included in the informed consent document. 
10.4.2 Benefits 
The potential benefit to a patient that goes onto study is a reduction in the bulk of their tumor which 
may or may not have favorable impact on symptoms and/or survival.  
10.5 Risks/Benefits Analysis for All Participants 
For patients with advanced pancreas cancer, median survival is in the range of 6 months. It is 
possible that treatment on this protocol may reduce tumor burden or lessen symptoms caused by the 
cancer. While treatment on this protocol may not individually benefit subjects, the knowledge 
gained from this study may help others in the future who have pancreatic cancer. Potential risks 
include the possible occurrence of any of a range of side effects listed. If patients suffer any physical

11 PHARMACEUTICAL INFORMATION 
11.1  M7824  
Other names: Anti PDL-1 TGF Beta-Trap, “TRAP”, MSB0011359C 
The finished injectable dosage form is manufactured by EMD 6HURQR5HVHDUFK	'HYHORSPHQW
Institute, Inc. 
11.1.1 Status: 
For Investigational Use Only. 
11.1.2 Brief Mechanism of Action/Drug Classification: 
M7824 is a fully human antibody of the IgG1 isotype designed as a single molecule that blocks 
the following two major immune escape mechanisms (negative immunoregulatory pathways) 
simultaneously: PD-L1/PD1 signaling and TGF-EHWDVLJQDOLQJ3'/LVKLJKO\H[SUHVVHGLQWXPRU
cells, which strongly correlates with poor prognosis in a variety of human cancers. TGF-beta is 
associated with malignant progression, evasion of immune surveillance, invasion and metastasis. 
Elevated levels of TGF-beta correlate with poor outcome in many different human cancers. 
11.1.3 How Supplied: 
M7824 is supplied in two different formulations: a sterile lyophilized powder and a sterile liquid. 
Lyophilized (freeze-dried) formulation: 
Supplied as a Type 1 glass vial containing a white lyophilized powder. Each vial contains 45 mg

13.3 Appendix C: Modified Immune-related Response Criteria (irRECIST) 
This new classification is based on the recent learning from clinical studies with cancer 
immunotherapies that even if some new lesions appear at the beginning of a treatment or if the 
total tumor burden does not increase substantially, tumor regressions or stabilizations might still 
occur later. The irRC were created using bi-dimensional measurements (as previously widely used 
in the World Health Organization criteria). For this trial, the concepts of the irRC are combined 
with RECIST 1.1 to come up with the modified irRC.  
For modified irRC, only target and measurable lesions are taken into account. In contrast to the 
RECIST 1.1 criteria, the modified irRC criteria (a) require confirmation of both progression and 
response by imaging at 6 weeks after initial imaging and (b) do not necessarily score the 
appearance of new lesions as progressive disease if the sum of lesion diameters of target lesions 
(minimum of 10 PPSHUOHVLRQPD[LPXPRIWDUJHWOHVLRQVPD[LPXPRISHURUJDQDQG
PHDVXUDEOHQHZOHVLRQVGRHVQRWLQFUHDVHE\ 
The same method of assessment and the same technique should be used to characterize each 
identified and reported target lesion(s) at baseline, during the trial, and at the end of trial visit. All 
measurements should be recorded in metric notation. The modified irRC based on RECIST 1.1 are 
displayed below.
