Brief summary:
This is a phase 1b/2 study to evaluate the safety and efficacy of metronomic combination therapy in subjects with pancreatic cancer who have progressed on or after previous SoC chemotherapy.

Detailed description:
Treatment will be administered in two phases, an induction and a maintenance phase, as described below. Subjects will continue induction treatment for up to 1 year. Treatment in the study will be discontinued if the subject experiences progressive disease (PD) or unacceptable toxicity (not corrected with dose reduction), withdraws consent, or if the Investigator feels it is no longer in the subject's best interest to continue treatment. Those who have a complete response (CR) in the induction phase will enter the maintenance phase of the study. Subjects who experience ongoing stable disease (SD) or an ongoing partial response (PR) at 1 year may enter the maintenance phase at the Investigator's discretion. Subjects may remain on the maintenance phase of the study for up to 1 year. Treatment will continue in the maintenance phase until the subject experiences PD or unacceptable toxicity (not corrected with dose reduction), withdraws consent, or if the Investigator feels it is no longer in the subject's best interest to continue treatment. The maximum time on study treatment, including both the induction and maintenance phases, is 2 years.

Study Objectives: 
Phase 1b 
• 
The primary objective is to evaluate the overall safety profile of the NANT pancreatic 
cancer vaccine regimen in subjects with pancreatic cancer who have progressed on or 
after standard-of-care (SoC) therapy. 
• 
Secondary objectives are to obtain preliminary estimates of efficacy by objective 
response rate (ORR), progression-free survival (PFS), overall survival (OS), duration of 
response (DOR), disease control rate (DCR), and quality of life (QoL) by patient-reported 
outcomes (PROs). 
• 
Exploratory objectives include the assessment of tumor molecular profiles (genomics, 
transcriptomics, and proteomics), therapy-induced changes in immune responses, and 
molecular changes in circulating tumor DNA (ctDNA) and RNA (ctRNA); and their 
correlations with subject outcomes. 
Phase 2  
• 
The primary objective is to determine the efficacy of the NANT pancreatic cancer 
vaccine regimen as assessed by ORR using RECIST Version 1.1. 
• 
Secondary objectives are to obtain additional measures of safety and efficacy (PFS, OS, 
DOR, DCR, and QoL by PROs). 
• 
Exploratory objectives include the assessment of tumor molecular profiles, therapy-
induced changes in immune responses, and molecular changes in ctDNA and ctRNA; and 
their correlations with subject outcomes. 
Study Design: 
This is a phase 1b/2 study to evaluate the safety and efficacy of metronomic combination therapy in 
subjects with pancreatic cancer who have progressed on or after previous SoC chemotherapy.  
In phase 1b, the initial 3 subjects will be enrolled in a staggered fashion, with a 21-day interval 
between each subject to enable the capture and monitoring of any acute and subacute toxicities. 
Preliminary assessment of the safety of the treatment regimen will occur by the NantKwest Safety 
Review Committee (SRC). Enrollment into the phase 1b portion will continue if data from the initial 
3 subjects suggest that the combination therapy is tolerable. 
In phase 2, subjects will be enrolled into 1 of 2 cohorts: (1) subjects who have failed first-line SoC 
therapy (first-line metastatic or progressed after adjuvant chemotherapy specifically including 
FOLFIRINOX, gemcitabine and nab-paclitaxel, gemcitabine and capecitabine, or gemcitabine alone), 
and (2) subjects who have been treated with more than one line of SoC therapy. In phase 2, ORR will 
be evaluated separately for each cohort using Simon’s two-stage optimal design. 
Treatment will be administered in two phases, an induction and a maintenance phase, as described 
below. Subjects will continue induction treatment for up to 1 year. Treatment in the study will be 
discontinued if the subject experiences progressive disease (PD) or unacceptable toxicity (not 
corrected with dose reduction), withdraws consent, or if the Investigator feels it is no longer in the 
subject’s best interest to continue treatment. Those who have a complete response (CR) in the 
induction phase will enter the maintenance phase of the study. Subjects who experience ongoing 
stable disease (SD) or an ongoing partial response (PR) at 1 year may enter the maintenance phase at 


NANT Pancreatic Cancer Vaccine 
NantKwest, Inc. 
Clinical Trial Protocol: QUILT-3.070 Amendment 2 
 
Confidential and Proprietary 
6 
the Investigator’s discretion. Subjects may remain on the maintenance phase of the study for up to 1 
year. Treatment will continue in the maintenance phase until the subject experiences PD or 
unacceptable toxicity (not corrected with dose reduction), withdraws consent, or if the Investigator 
feels it is no longer in the subject’s best interest to continue treatment. The maximum time on study 
treatment, including both the induction and maintenance phases, is 2 years. 
Exploratory tumor molecular profiling will be conducted on samples collected prior to treatment on 
this study, 8 weeks after the start of treatment, and during potential prolonged induction and 
maintenance phases (depending on response), as described in Section 6.4.1. Separate blood tubes will 
be collected every 6 weeks in the induction phase and every 8 weeks in the maintenance phase during 
routine blood draws for exploratory immunology and ctDNA/ctRNA analyses, as described in 
Section 6.4.2 and Section 6.4.3, respectively. 
Tumors will be assessed at screening, and tumor response will be assessed every 8 weeks during the 
induction phase, and every 12 weeks during the maintenance phase by computed tomography (CT), 
magnetic resonance imaging (MRI), or positron emission tomography-computed tomography 
(PET-CT) of target and non-target lesions in accordance with Response Evaluation Criteria in Solid 
Tumors (RECIST) Version 1.1 and immune-related response criteria (irRC). 
Prospective Tumor Molecular Profiling 
Prospective tumor molecular profiling will be conducted to inform RAS mutational status, and will be 
used to determine whether GI-4000 will be administered. GI-4000 administration will be initiated as 
soon as results from tumor molecular profiling are available. All subjects will receive all other agents 
regardless of their tumor molecular profile. 
Prospective tumor molecular profiling will be performed on FFPE tumor tissue and whole blood 
(subject-matched normal comparator against the tumor tissue) collected prior to treatment on this 
study. Treatment with all study drugs except GI-4000 may be initiated before FFPE tumor tissue 
and/or results from prospective tumor molecular profiling are available; in the event that this occurs, 
treatment of subjects with tumors positive for specific RAS mutations targeted by GI-4000 will begin 
as soon as molecular profiling results are available. More information on the collection of tumor 
tissue and whole blood is described in Section 6.4.1.2 and is similar to the collection of samples for 
the exploratory tumor molecular profiling. 
Subjects will receive GI-4000 if their tumor is positive for specific RAS mutations, as determined by 
whole genome sequencing. As described in Section 1.6.9, GI-4000 is 4 separate products from the GI-
4000 series (GI-4014, GI-4015, GI- 4016, and GI-4020); each of these expresses a combination of 
mutated RAS oncoproteins. The specific RAS mutation will determine which GI-4000 product will be 
used for treatment (GI-4014 for G12V, GI-4015 for G12C, GI-4016 for G12D, GI-4020 for G12R or 
Q61H, and GI-4014, GI-4015, or GI-4016 for Q61L or Q61R). 
Induction Phase: 
The induction phase will consist of repeated 3-week cycles for a maximum treatment period of 1 year. 
The treatment regimen of aldoxorubicin HCl, ALT-803, avelumab, bevacizumab, cyclophosphamide, 
Ad5-based vaccine (ETBX-011), 5-FU/leucovorin, yeast-based vaccine (GI-4000), haNK, 
nab-paclitaxel, omega-3-acid ethyl esters, and oxaliplatin will be repeated every 3 weeks. Concurrent 
SBRT will be given during the first two 3-week cycles. Radiation will be administered to no more 
than 5 tumor sites using SBRT, as described in Section 5.1.5.1. 
The induction phase of study treatment will be conducted in accordance with the following dosing 
regimen:

enrolled in a staggered fashion, with a 21-day interval between each subject.  
In the phase 2 portion of the study, ORR will be evaluated separately using Simon’s two-stage 
optimal design for cohorts that include: (1) subjects who have failed first-line SoC therapy (first-line 
metastatic or progressed after adjuvant chemotherapy specifically including FOLFIRINOX, 
gemcitabine and nab-paclitaxel, gemcitabine and capecitabine, or gemcitabine alone), and (2) subjects 
who have been treated with more than one line of SoC therapy. 
For cohort 1, 37 subjects will be enrolled in the first stage of Simon’s two-stage optimal design. If the 
study proceeds to the second stage of Simon’s two-stage optimal design, an additional 57 subjects 
will be enrolled in the second stage, for a total of 94 subjects in the phase 2 portion of the study for 
cohort 1.  
For cohort 2, 23 subjects will be enrolled in the first stage of Simon’s two-stage optimal design. If the 
study proceeds to the second stage of Simon’s two-stage optimal design, an additional 32 subjects 
will be enrolled in the second stage, for a total of 55 subjects in the phase 2 portion of the study for 
cohort 2.  
The maximum total enrollment for the study is 173 subjects.

Evaluation of Endpoints: 
Safety:  
Safety endpoints include assessments of treatment-emergent AEs, SAEs, and clinically significant 
changes in safety laboratory tests, physical examinations, electrocardiograms (ECGs), 
echocardiograms (ECHOs), and vital signs. All subjects will be evaluable for toxicity from the time 
of their first study treatment. Toxicities will be graded using the NCI CTCAE Version 4.03. 
Efficacy: 
ORR and PFS will be assessed by CT of target and non-target lesions every 8 weeks during the 
induction phase and every 12 weeks during the maintenance phase and will be evaluated in 
accordance with RECIST Version 1.1 and irRC. OS, DOR, and DCR will also be assessed. 
An assessment of QoL will be conducted via PROs using the Functional Assessment of Cancer 
Therapy-Hepatobiliary Cancer (FACT-Hep) instrument on study day 1, every 6 weeks thereafter 
(day 1 of weeks 7, 13, 19, etc.) prior to treatment during induction phase, every 12 weeks during 
maintenance, and at the end-of-treatment (EOT) visit. 
Exploratory Analysis: 
Tumor Molecular Profiling: Genomic sequencing of tumor cells from tissue relative to non-tumor 
cells from whole blood will be conducted to identify tumor-specific genomic variances that may 
contribute to disease progression and/or response to treatment. RNA sequencing will be conducted to 
provide expression data and give relevance to DNA mutations. Quantitative proteomics analysis will 
be conducted to determine the absolute amounts of specific proteins, to confirm expression of genes 
that are correlative of disease progression and/or response, and to determine the cutoff values for 
response. 
Immunologic Analysis: Immune responses to the NANT pancreatic cancer regimen will be evaluated 
by standard immune assays. Correlations between therapy-induced immune changes and subject 
outcomes will be assessed. 
ctDNA/ctRNA Analysis: ctDNA and ctRNA will be extracted from plasma obtained from whole 
blood. Expression levels of specific tumor- and immune-related analytes will be assessed by 
quantitative real-time polymerase chain reaction (qPCR) and possibly other methods (eg, DNA/RNA 
sequencing) and analyzed for correlations with subject outcomes. 
Statistical Methods: 
This phase 1b/2 study will examine the overall safety profile and efficacy of metronomic combination 
therapy in subjects with pancreatic cancer whose tumors have progressed on or after SoC treatment. 
Safety results will be presented separately for the induction and maintenance phases of treatment as 
well as overall for the entire treatment regimen. Efficacy results will be summarized for the overall 
treatment regimen and presented separately for cohorts 1 and 2 
Overall safety will be assessed by descriptive analyses using tabulated frequencies of AEs by grade 
using CTCAE version 4.03 in terms of treatment-emergent AEs, SAEs, and clinically significant 
changes in safety laboratory tests, physical examinations, ECGs, ECHOs, and vital signs. 
ORR will be evaluated in accordance with RECIST Version 1.1 and irRC. The percentage of subjects 
(and 95% confidence interval [CI]) who achieve a confirmed response will be summarized. DCR will 
be evaluated similar to ORR. PFS, OS, and DOR will be analyzed using Kaplan-Meier methods. 
Descriptive statistics of PROs will be presented. 
Correlations of tumor molecular profiles, therapy-induced changes in immune responses, and 
molecular changes in ctDNA and ctRNA with subject outcomes will be explored.

Study Objectives: 
Phase 1b 
• 
The primary objective is to evaluate the overall safety profile of the NANT pancreatic 
cancer vaccine regimen in subjects with pancreatic cancer who have progressed on or 
after standard-of-care (SoC) therapy. 
• 
Secondary objectives are to obtain preliminary estimates of efficacy by objective 
response rate (ORR), progression-free survival (PFS), overall survival (OS), duration of 
response (DOR), disease control rate (DCR), and quality of life (QoL) by patient-reported 
outcomes (PROs). 
• 
Exploratory objectives include the assessment of tumor molecular profiles (genomics, 
transcriptomics, and proteomics), therapy-induced changes in immune responses, and 
molecular changes in circulating tumor DNA (ctDNA) and RNA (ctRNA); and their 
correlations with subject outcomes. 
Phase 2  
• 
The primary objective is to determine the efficacy of the NANT pancreatic cancer 
vaccine regimen as assessed by ORR. 
• 
Secondary objectives are to obtain additional measures of safety and efficacy (PFS, OS, 
DOR, DCR, and QoL by PROs). 
• 
Exploratory objectives include the assessment of tumor molecular profiles, therapy-
induced changes in immune responses, and molecular changes in ctDNA and ctRNA; and 
their correlations with subject outcomes. 
Study Design: 
This is a phase 1b/2 study to evaluate the safety and efficacy of metronomic combination therapy in 
subjects with pancreatic cancer who have progressed on or after previous SoC chemotherapy. In 
phase 2, subjects will be enrolled into 1 of 2 cohorts: (1) subjects who have failed first-line SoC 
therapy (first-line metastatic or progressed after adjuvant chemotherapy specifically including 
FOLFIRINOX, gemcitabine and nab-paclitaxel, gemcitabine and capecitabine, or gemcitabine alone), 
and (2) subjects who have been treated with more than one line of SoC therapy. In phase 2, ORR will 
be evaluated separately for each cohort using Simon’s two-stage optimal design. 
Preliminary assessment of the safety of the treatment regimen will occur by the NantKwest Safety 
Review Committee (SRC). Enrollment into the phase 1b portion will continue if data from the initial 
3 subjects suggest that the combination therapy is tolerable. 
Treatment will be administered in two phases, an induction and a maintenance phase, as described 
below. Subjects will continue induction treatment for up to 1 year. Treatment in the study will be 
discontinued if the subject experiences progressive disease (PD) or unacceptable toxicity (not 
corrected with dose reduction), withdraws consent, or if the Investigator feels it is no longer in the 
subject’s best interest to continue treatment. Those who have a complete response (CR) in the 
induction phase will enter the maintenance phase of the study. Subjects who experience ongoing 
stable disease (SD) or an ongoing partial response (PR) at 1 year may enter the maintenance phase at 


NANT Pancreatic Cancer Vaccine 
NantKwest, Inc. 
Clinical Trial Protocol: QUILT-3.070 
 
Confidential and Proprietary 
6 
the Investigator’s discretion. Subjects may remain on the maintenance phase of the study for up to 1 
year. Treatment will continue in the maintenance phase until the subject experiences PD or 
unacceptable toxicity (not corrected with dose reduction), withdraws consent, or if the Investigator 
feels it is no longer in the subject’s best interest to continue treatment. The maximum time on study 
treatment, including both the induction and maintenance phases, is 2 years. 
Exploratory tumor molecular profiling will be conducted on samples collected prior to treatment on 
this study, 8 weeks after the start of treatment, and during potential prolonged induction and 
maintenance phases (depending on response), as described in Section 6.4.1. Separate blood tubes will 
be collected every 6 weeks in the induction phase and every 8 weeks in the maintenance phase during 
routine blood draws for exploratory immunology and ctDNA/ctRNA analyses, as described in 
Section 6.4.2 and Section 6.4.3, respectively. 
Tumors will be assessed at screening, and tumor response will be assessed every 8 weeks during the 
induction phase, and every 12 weeks during the maintenance phase by computed tomography (CT) of 
target and non-target lesions in accordance with Response Evaluation Criteria in Solid Tumors 
(RECIST) Version 1.1 and immune-related response criteria (irRC). 
Prospective Tumor Molecular Profiling 
Prospective tumor molecular profiling will be conducted to inform RAS mutational status, and will be 
used to determine whether GI-4000 will be administered. GI-4000 administration will be initiated as 
soon as results from tumor molecular profiling are available. All subjects will receive all other agents 
regardless of their tumor molecular profile. 
Prospective tumor molecular profiling will be performed on FFPE tumor tissue and whole blood 
(subject-matched normal comparator against the tumor tissue) collected prior to treatment on this 
study. Treatment with all study drugs except GI-4000 may be initiated before FFPE tumor tissue 
and/or results from prospective tumor molecular profiling are available; in the event that this occurs, 
treatment of subjects with tumors positive for specific RAS mutations targeted by GI-4000 will begin 
as soon as molecular profiling results are available. More information on the collection of tumor 
tissue and whole blood is described in Section 6.4.1.2 and is similar to the collection of samples for 
the exploratory tumor molecular profiling. 
Subjects will receive GI-4000 if their tumor is positive for specific RAS mutations, as determined by 
whole genome sequencing. As described in Section 1.6.9, GI-4000 is 4 separate products from the GI-
4000 series (GI-4014, GI-4015, GI- 4016, and GI-4020); each of these expresses a combination of 
mutated RAS oncoproteins. The specific RAS mutation will determine which GI-4000 product will be 
used for treatment (GI-4014 for G12V, GI-4015 for G12C, GI-4016 for G12D, GI-4020 for G12R or 
Q61H, and GI-4014, GI-4015, or GI-4016 for Q61L or Q61R). 
Induction Phase: 
The induction phase will consist of repeated 3-week cycles for a maximum treatment period of 1 year. 
The treatment regimen of aldoxorubicin HCl, ALT-803, avelumab, bevacizumab, cyclophosphamide, 
Ad5-based vaccine (ETBX-011), 5-FU/leucovorin, yeast-based vaccine (GI-4000), haNK, 
nab-paclitaxel, omega-3-acid ethyl esters, and oxaliplatin will be repeated every 3 weeks. Concurrent 
stereotactic body radiotherapy (SBRT) will be given during the first two 3-week cycles. Radiation 
will be administered to no more than 5 tumor sites using SBRT, as described in Section 5.1.5.1.

Enrollment (planned): 
In the phase 1b portion of the study, 6 to 24 subjects will be enrolled. 
In the phase 2 portion of the study, ORR will be evaluated separately using Simon’s two-stage 
optimal design for cohorts that include: (1) subjects who have failed first-line SoC therapy (first-line 
metastatic or progressed after adjuvant chemotherapy specifically including FOLFIRINOX, 
gemcitabine and nab-paclitaxel, gemcitabine and capecitabine, or gemcitabine alone), and (2) subjects 
who have been treated with more than one line of SoC therapy. 
 For cohort 1, 37 subjects will be enrolled in the first stage of Simon’s two-stage optimal design. If 
the study proceeds to the second stage of Simon’s two-stage optimal design, an additional 57 subjects 
will be enrolled in the second stage, for a total of 94 subjects in the phase 2 portion of the study for 
cohort 1.  
For cohort 2, 23 subjects will be enrolled in the first stage of Simon’s two-stage optimal design. If the 
study proceeds to the second stage of Simon’s two-stage optimal design, an additional 32 subjects 
will be enrolled in the second stage, for a total of 55 subjects in the phase 2 portion of the study for 
cohort 2.  
The maximum total enrollment for the study is 173 subjects.

Evaluation of Endpoints: 
Safety:  
Safety endpoints include assessments of treatment-emergent AEs, SAEs, and clinically significant 
changes in safety laboratory tests, physical examinations, electrocardiograms (ECGs), 
echocardiograms (ECHOs), and vital signs. All subjects will be evaluable for toxicity from the time 
of their first study treatment. Toxicities will be graded using the NCI CTCAE Version 4.03. 
Efficacy: 
ORR and PFS will be assessed by CT of target and non-target lesions every 8 weeks during the 
induction phase and every 12 weeks during the maintenance phase and will be evaluated in 
accordance with RECIST Version 1.1 and irRC. OS, DOR, and DCR will also be assessed. 
An assessment of QoL will be conducted via PROs using the Functional Assessment of Cancer 
Therapy-Hepatobiliary Cancer (FACT-Hep) instrument on study day 1, every 6 weeks thereafter 
(day 1 of weeks 7, 13, 19, etc.) prior to treatment during induction phase, every 12 weeks during 
maintenance, and at the end-of-treatment (EOT) visit. 
Exploratory Analysis: 
Tumor Molecular Profiling: Genomic sequencing of tumor cells from tissue relative to non-tumor 
cells from whole blood will be conducted to identify tumor-specific genomic variances that may 
contribute to disease progression and/or response to treatment. RNA sequencing will be conducted to 
provide expression data and give relevance to DNA mutations. Quantitative proteomics analysis will 
be conducted to determine the absolute amounts of specific proteins, to confirm expression of genes 
that are correlative of disease progression and/or response, and to determine the cutoff values for 
response. 
Immunologic Analysis: Immune responses to the NANT pancreatic cancer regimen will be evaluated 
by standard immune assays. Correlations between therapy-induced immune changes and subject 
outcomes will be assessed. 
ctDNA/ctRNA Analysis: ctDNA and ctRNA will be extracted from plasma obtained from whole 
blood. Expression levels of specific tumor- and immune-related analytes will be assessed by 
quantitative real-time polymerase chain reaction (qPCR) and possibly other methods (eg, DNA/RNA 
sequencing) and analyzed for correlations with subject outcomes.

Statistical Methods: 
This phase 1b/2 study will examine the overall safety profile and efficacy of metronomic combination 
therapy in subjects with pancreatic cancer whose tumors have progressed on or after SoC treatment. 
Safety results will be presented separately for the induction and maintenance phases of treatment as 
well as overall for the entire treatment regimen. Efficacy results will be summarized for the overall 
treatment regimen and presented separately for cohorts 1 and 2 
Overall safety will be assessed by descriptive analyses using tabulated frequencies of AEs by grade 
using CTCAE version 4.03 in terms of treatment-emergent AEs, SAEs, and clinically significant 
changes in safety laboratory tests, physical examinations, ECGs, ECHOs, and vital signs. 
ORR will be evaluated in accordance with RECIST Version 1.1 and irRC. The percentage of subjects 
(and 95% confidence interval [CI]) who achieve a confirmed response will be summarized. DCR will 
be evaluated similar to ORR. PFS, OS, and DOR will be analyzed using Kaplan-Meier methods. 
Descriptive statistics of PROs will be presented. 
Correlations of tumor molecular profiles, therapy-induced changes in immune responses, and 
molecular changes in ctDNA and ctRNA with subject outcomes will be explored.

Study Objectives: 
Phase 1b 
• 
The primary objective is to evaluate the overall safety profile of the NANT pancreatic 
cancer vaccine regimen in subjects with pancreatic cancer who have progressed on or 
after standard-of-care (SoC) therapy. 
• 
Secondary objectives are to obtain preliminary estimates of efficacy by objective 
response rate (ORR), progression-free survival (PFS), overall survival (OS), duration of 
response (DOR), disease control rate (DCR), and quality of life (QoL) by patient-reported 
outcomes (PROs). 
• 
Exploratory objectives include the assessment of cancer antigen 19-9 (CA 19-9), tumor 
molecular profiles (genomics, transcriptomics, and proteomics), therapy-induced changes 
in immune responses, and molecular changes in circulating tumor DNA (ctDNA) and 
RNA (ctRNA); and their correlations with subject outcomes. 
Phase 2  
• 
The primary objective is to determine the efficacy of the NANT pancreatic cancer 
vaccine regimen as assessed by ORR using RECIST Version 1.1 based on Blinded 
Independent Central Review (BICR). 
• 
Secondary objectives are to obtain additional measures of safety and efficacy (PFS, OS, 
DOR, DCR, and QoL by PROs). 
• 
Exploratory objectives include the assessment of CA 19-9, tumor molecular profiles, 
therapy-induced changes in immune responses, and molecular changes in ctDNA and 
ctRNA; and their correlations with subject outcomes. 
Study Design: 
This is a phase 1b/2 study to evaluate the safety and efficacy of metronomic combination therapy in 
subjects with pancreatic cancer who have progressed on or after previous SoC chemotherapy.  
In phase 1b, the initial 3 subjects will be enrolled in a staggered fashion, with a 21-day interval 
between each subject to enable the capture and monitoring of any acute and subacute toxicities. 
Preliminary assessment of the safety of the treatment regimen will occur by the NantKwest Safety 
Review Committee (SRC). Enrollment into the phase 1b portion will continue if data from the initial 
3 subjects suggest that the combination therapy is tolerable. 
In phase 2, subjects will be enrolled into 1 of 2 cohorts: (1) subjects who have failed first-line SoC 
therapy (first-line metastatic or progressed after adjuvant chemotherapy specifically including 
FOLFIRINOX, gemcitabine and nab-paclitaxel, gemcitabine and capecitabine, or gemcitabine alone), 
and (2) subjects who have been treated with more than one line of SoC therapy. In phase 2, ORR will 
be evaluated separately for each cohort using Simon’s two-stage optimal design. 
Treatment will be administered in two phases, an induction and a maintenance phase, as described 
below. Subjects will continue induction treatment for up to 1 year. Treatment in the study will be 
discontinued if the subject experiences progressive disease (PD) or unacceptable toxicity (not 
corrected with dose reduction), withdraws consent, or if the Investigator feels it is no longer in the 
subject’s best interest to continue treatment. Those who have a complete response (CR) in the 
induction phase will enter the maintenance phase of the study. Subjects who experience ongoing

NANT Pancreatic Cancer Vaccine 
NantKwest, Inc. 
Clinical Trial Protocol: QUILT-3.070 Amendment 3 
 
stable disease (SD) or an ongoing partial response (PR) at 1 year may enter the maintenance phase at 
the Investigator’s discretion. Subjects may remain on the maintenance phase of the study for up to 1 
year. Treatment will continue in the maintenance phase until the subject experiences PD or 
unacceptable toxicity (not corrected with dose reduction), withdraws consent, or if the Investigator 
feels it is no longer in the subject’s best interest to continue treatment. The maximum time on study 
treatment, including both the induction and maintenance phases, is 2 years. 
Exploratory tumor molecular profiling will be conducted on samples collected prior to treatment on 
this study, 8 weeks after the start of treatment, and during potential prolonged induction and 
maintenance phases (depending on response), as described in Section 6.4.1. Separate blood tubes will 
be collected every 6 weeks in the induction phase and every 8 weeks in the maintenance phase during 
routine blood draws for exploratory immunology and ctDNA/ctRNA analyses, as described in 
Section 6.4.2 and Section 6.4.3, respectively. 
Tumors will be assessed at screening, and tumor response will be assessed every 8 weeks during the 
induction phase, and every 12 weeks during the maintenance phase by computed tomography (CT), 
magnetic resonance imaging (MRI), or positron emission tomography-computed tomography 
(PET-CT) of target and non-target lesions in accordance with Response Evaluation Criteria in Solid 
Tumors (RECIST) Version 1.1 and immune-related response criteria (irRC). In order to document 
PD, unscheduled tumor assessments may be done if the Investigator observes any signs and 
symptoms of PD.  For responding subjects (PR or CR), a confirmatory response assessment should be 
done at 4 weeks after the initial response. 
Prospective Tumor Molecular Profiling 
Prospective tumor molecular profiling will be conducted to inform RAS mutational status, and will be 
used to determine whether GI-4000 will be administered. GI-4000 administration will be initiated as 
soon as results from tumor molecular profiling are available. All subjects will receive all other agents 
regardless of their tumor molecular profile. 
Prospective tumor molecular profiling will be performed on FFPE tumor tissue and whole blood 
(subject-matched normal comparator against the tumor tissue) collected prior to treatment on this 
study, as described in Section 3.1.1. More information on the collection of tumor tissue and whole 
blood is described in Section 6.4.1.2 and is similar to the collection of samples for the exploratory 
tumor molecular profiling. 
Subjects will receive GI-4000 if their tumor is positive for specific RAS mutations, as determined by 
whole genome sequencing.  
Induction Phase: 
Treatment in the induction phase will consist of repeated 3-week cycles for a maximum treatment 
period of 1 year, as follows: 
Day 1, every 3 weeks:  
• 
Bevacizumab (5 mg/kg IV)  
• 
Leucovorin (20 mg/m2 IV bolus) 
• 
Nab-paclitaxel (125 mg IV) 
• 
Oxaliplatin (40 mg/m2 IV)

prepared by the vendor selected to perform the independent review. 
Enrollment (planned): 
In the phase 1b portion of the study, 6 to 24 subjects will be enrolled. The initial 3 subjects will be 
enrolled in a staggered fashion, with a 21-day interval between each subject.  
In the phase 2 portion of the study, ORR will be evaluated separately using Simon’s two-stage 
optimal design for cohorts that include: (1) subjects who have failed first-line SoC therapy (first-line 
metastatic or progressed after adjuvant chemotherapy specifically including FOLFIRINOX, 
gemcitabine and nab-paclitaxel, gemcitabine and capecitabine, or gemcitabine alone), and (2) subjects 
who have been treated with more than one line of SoC therapy. 
For cohort 1, 37 subjects will be enrolled in the first stage of Simon’s two-stage optimal design. If the 
study proceeds to the second stage of Simon’s two-stage optimal design, an additional 57 subjects 
will be enrolled in the second stage, for a total of 94 subjects in the phase 2 portion of the study for 
cohort 1.  
For cohort 2, 23 subjects will be enrolled in the first stage of Simon’s two-stage optimal design. If the 
study proceeds to the second stage of Simon’s two-stage optimal design, an additional 32 subjects 
will be enrolled in the second stage, for a total of 55 subjects in the phase 2 portion of the study for 
cohort 2.  
The maximum total enrollment for the study is 173 subjects.

Duration of Treatment: 
• 
Induction phase: 8 weeks (minimum) to 1 year (maximum). 
• 
Maintenance phase: Up to 1 year. 
Subjects will be treated for up to 2 years (up to 1 year in each treatment phase) or until they 
experience progressive disease, unacceptable toxicity (not corrected with dose reduction), withdraw 
consent, or if the Investigator feels it is no longer in their best interest to continue treatment. 
Duration of Follow-up:  
Subjects who discontinue study treatment should remain in the study and continue to be followed 
every 90 days (± 14 days) for: 
• 
Resolution of any SAEs attributed to treatment (see Section 7) 
• 
CT, MRI, or PET-CT scan assessment (see Section 6.1.2) 
• 
Vital status: subjects will be followed until either death or for a minimum of 18 months 
past administration of the first dose of chemotherapy to the last subject enrolled in the 
study, whichever comes first. 
Subjects may continue to be followed by the investigational physician or a third party by phone or 
review of medical records approximately every 90 days until withdrawal of consent, lost to follow-up, 
or death (by any cause). Additional information from a subject’s medical records relevant to this 
study may be provided to NantKwest as needed to understand the safety and efficacy of the regimen 
tested in this protocol.

Evaluation of Endpoints: 
Safety:  
Safety endpoints include assessments of treatment-emergent AEs, SAEs, and clinically significant 
changes in safety laboratory tests, physical examinations, electrocardiograms (ECGs), 
echocardiograms (ECHOs), and vital signs. All subjects will be evaluable for toxicity from the time 
of their first study treatment. Toxicities will be graded using the NCI CTCAE Version 4.03. 
Efficacy: 
ORR and PFS will be assessed by CT of target and non-target lesions every 8 weeks during the 
induction phase and every 12 weeks during the maintenance phase and will be evaluated in 
accordance with RECIST Version 1.1 and irRC. In order to document PD, unscheduled tumor 
assessments may be done if the investigator observes any signs and symptoms of PD. For responding 
subjects (PR or CR), a confirmatory response assessment should be done at 4 weeks after the initial 
response.  
OS, DOR, and DCR will also be assessed. In the phase 1b portion of the study, response will be 
assessed by the Investigator; in the phase 2 portion of the study, the primary assessment of response 
will be based on the BICR. 
An assessment of QoL will be conducted via PROs using the Functional Assessment of Cancer 
Therapy-Hepatobiliary Cancer (FACT-Hep) instrument on study day 1, every 6 weeks thereafter 
(day 1 of weeks 7, 13, 19, etc.) prior to treatment during induction phase, every 12 weeks during 
maintenance, and at the end-of-treatment (EOT) visit. 
Exploratory Analysis: 
Tumor Molecular Profiling: Genomic sequencing of tumor cells from tissue relative to non-tumor 
cells from whole blood will be conducted to identify tumor-specific genomic variances that may 
contribute to disease progression and/or response to treatment. RNA sequencing will be conducted to 
provide expression data and give relevance to DNA mutations. Quantitative proteomics analysis will 
be conducted to determine the absolute amounts of specific proteins, to confirm expression of genes 
that are correlative of disease progression and/or response, and to determine the cutoff values for 
response. 
Immunologic Analysis: Immune responses to the NANT pancreatic cancer regimen will be evaluated 
by standard immune assays. Correlations between therapy-induced immune changes and subject 
outcomes will be assessed. 
ctDNA/ctRNA Analysis: ctDNA and ctRNA will be extracted from plasma obtained from whole 
blood. Expression levels of specific tumor- and immune-related analytes will be assessed by 
quantitative real-time polymerase chain reaction (qPCR) and possibly other methods (eg, DNA/RNA 
sequencing) and analyzed for correlations with subject outcomes.

Statistical Methods: 
This phase 1b/2 study will examine the overall safety profile and efficacy of metronomic combination 
therapy in subjects with pancreatic cancer whose tumors have progressed on or after SoC treatment. 
Safety results will be presented separately for the induction and maintenance phases of treatment as 
well as overall for the entire treatment regimen. Efficacy results will be summarized for the overall 
treatment regimen and presented separately for cohorts 1 and 2. 
Overall safety will be assessed by descriptive analyses using tabulated frequencies of AEs by grade 
using CTCAE version 4.03 in terms of treatment-emergent AEs, SAEs, and clinically significant 
changes in safety laboratory tests, physical examinations, ECGs, ECHOs, and vital signs. 
ORR will be evaluated in accordance with RECIST Version 1.1 and irRC. The percentage of subjects 
(and 95% confidence interval [CI]) who achieve a confirmed response will be summarized. DCR will 
be evaluated similar to ORR. PFS, OS, and DOR will be analyzed using Kaplan-Meier methods. 
Descriptive statistics of PROs will be presented. 
Correlations of tumor molecular profiles, therapy-induced changes in immune responses, and 
molecular changes in ctDNA and ctRNA with subject outcomes will be explored.
