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. Phase 2 will be based on Simon's two-stage optimal design.

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 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 regimen in subjects with pancreatic cancer who have progressed 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 
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.  Phase 
2 will be based on Simon’s two-stage optimal design. 
Preliminary assessment of the safety of the treatment regimen will occur by an independent Data 
Safety Monitoring Committee (IDMC) and 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 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

Confidential and Proprietary 
6 
phases, is 2 years. 
Exploratory tumor molecular profiling will be conducted on samples collected prior to treatment on 
this study, at the end of the initial induction phase (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 4 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 (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. 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 at screening. 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 1.6.8.1, 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 2-week cycles for a maximum treatment period of 1 year. 
The treatment regimen of 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 2 weeks.  Concurrent stereotactic body 
radiotherapy (SBRT) will be given during the first four 2-week cycles.  Radiation will be 
administered to no more than 5 tumor sites using SBRT, as described in Section 5.1.5.1.

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. 
Reference Therapy, Dosage, and Mode of Administration:  
Not applicable.

Evaluation of Endpoints: 
Safety:  
Safety endpoints include assessments of treatment-emergent AEs, SAEs, and clinically significant 
changes in safety laboratory tests, physical examinations, ECGs, 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, MRI, or PET-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 28 days thereafter, 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 flow cytometry and enzyme-linked immunospot (ELISpot) 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 preliminary 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. 
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, 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.

c Additional assessments performed during an unscheduled visit are at the discretion of the Investigator or treating physician and must be recorded in the 
subject’s source documents and on the Unscheduled Visit eCRF. 
d Inclusion/exclusion criteria will also be evaluated at enrollment. 
e Medical history will also be evaluated at enrollment. 
f Subject’s FFPE tumor tissue sample must be obtained following the conclusion of the most recent anticancer treatment and prior to first study treatment. If not 
available, a fresh tumor biopsy must be performed. In the event a fresh biopsy needs to be scheduled, the site may consent the subject and schedule the 
screening visit assessments to be performed such that all assessments fall within 28 days prior to the first dose of any study drug. If safety concerns preclude 
collection of a biopsy during the screening period, a tumor biopsy specimen collected prior to the conclusion of the most recent anticancer treatment may be 
used. 
g Height required at screening visit only. 
h Vital signs of temperature, heart rate, blood pressure, and respiratory rate will be assessed at every visit. Vitals signs are to be obtained after the subject has 
been in a seated resting position for at least 5 minutes. For visits where a subject is receiving an infusion of any study compounds, vital signs will be recorded 
at 15 minutes and 30 minutes after the start of the infusion and, except for 5-FU, at 30-minute intervals thereafter through the post-infusion hydration period. 
i 12-lead ECG to be performed in triplicate at screening. 
j Chemistry panel to include laboratory assessments noted in Table 18.  
k Day 1 assessments can be skipped if the screening assessment was performed within 1 week prior to the start of treatment. 
l Hematology to include CBC with differential (5 part) and platelets with hemoglobin and hematocrit. 
m Serum pregnancy test at screening; urine dipstick pregnancy test for all other visits (for females of child-bearing potential). 
n Virology tests include HIV (as determined by ELISA and confirmed by western blot) and HBV/HCV (as determined by HBsAg and hepatitis C serology). 
o Assessment of RAS mutational status to determine whether GI-4000 will be administered to the subject, as described in Section 3.1.1. 
p Whole blood for tumor molecular profiling will be collected during the screening period for subjects who have been enrolled in the study. 
q Whole blood for immunology and ctDNA/ctRNA analyses will be collected during the screening period for subjects who have been enrolled in the study, every 
4 weeks in the induction phase during routine blood draws, and at the EOT visit. 
r Historic tumor biopsy specimen for tumor molecular profiling will be collected only for subjects enrolled in the study. If an historic specimen is not available, a 
fresh tumor biopsy must be performed, if considered safe by the Investigator. If safety concerns preclude collection of a biopsy during the screening period, a 
tumor biopsy specimen collected prior to the conclusion of the most recent anticancer treatment may be used. In the event a fresh biopsy needs to be scheduled, 
the site may consent the subject and schedule the screening visit assessments to be performed such that all assessments fall within 28 days prior to the first dose 
of any study medications. If safety concerns preclude collection of a biopsy during the screening period, a tumor biopsy specimen collected prior to the 
conclusion of the most recent anticancer treatment may be used. A tumor biopsy is also required at the end of the initial induction phase (8 weeks after the start 
of treatment), if considered safe by the Investigator 
s Tumor imaging by CT scan, MRI, or PET-CT will be performed at screening and every 8 weeks thereafter in the induction phase. Evaluations may include CT, 
MRI, or PET-CT scans of the chest, abdomen, pelvis (optional unless known pelvic disease is present at screening), and brain (only as clinically warranted 
based on symptoms/findings). All screening tumor imaging assessments should be performed based on the subject's qualifying scan obtained within 28 days 
prior to the start of treatment. RECIST and irRC documentation to be completed at each assessment period. The same mode of imaging is required to be carried 
through each subject’s respective treatment period.

Study Objectives: 
Phase 1b 
• 
The primary objective is to evaluate the overall safety profile of the NANT pancreatic 
cancer regimen in subjects with pancreatic cancer who have progressed 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 
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. Phase 2 
will be based on Simon’s two-stage optimal design. 
Preliminary assessment of the safety of the treatment regimen will occur by an Independent Data 
Safety Monitoring Committee (IDMC) and 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 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 4 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 (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. 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 at screening. 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 1.6.8.1, 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:

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, ECGs, 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, MRI, or PET-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 28 days thereafter, 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 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 preliminary 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. 
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, 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.

f Subject’s FFPE tumor tissue sample must be obtained following the conclusion of the most recent anticancer treatment and prior to first study treatment. If not 
available, a fresh tumor biopsy must be performed. In the event a fresh biopsy needs to be scheduled, the site may consent the subject and schedule the 
screening visit assessments to be performed such that all assessments fall within 28 days prior to the first dose of any study drug. If safety concerns preclude 
collection of a biopsy during the screening period, a tumor biopsy specimen collected prior to the conclusion of the most recent anticancer treatment may be 
used. 
g Height required at screening visit only. 
h Vital signs of temperature, heart rate, blood pressure, and respiratory rate will be assessed at every visit. Vital signs are to be obtained after the subject has been 
in a seated resting position for at least 5 minutes and within 30 minutes prior to the start of any infusional study treatment. For visits where a subject is 
receiving an infusion of any study compounds, vital signs will be collected at the following time points in relation to the start of first infusion of the day: prior 
to infusion, 15 minutes post, 30 minutes post, and hourly until the subject is discharged. Temperature will be documented each visit at the first pre-infusion 
assessment of vital signs and subsequently if clinically indicated. 
i 12-lead ECG to be performed in triplicate at screening. 
j Chemistry panel to include laboratory assessments noted in Table 18.  
k Day 1 assessments can be skipped if the screening assessment was performed within 1 week prior to the start of treatment. 
l Hematology to include CBC with differential (5 part) and platelets with hemoglobin and hematocrit. 
m Serum pregnancy test for females of child-bearing potential. 
n Virology tests include HIV (as determined by ELISA and confirmed) and HBV/HCV (as determined by HBsAg and hepatitis C serology). 
o Assessment of RAS mutational status to determine whether GI-4000 will be administered to the subject, as described in Section 3.1.1. 
p Whole blood for tumor molecular profiling will be collected during the screening period for subjects who have been enrolled in the study. 
q Whole blood for immunology and ctDNA/ctRNA analyses will be collected during the screening period for subjects who have been enrolled in the study, every 
4 weeks in the induction phase during routine blood draws, and at the EOT visit. 
r Historic tumor biopsy specimen for tumor molecular profiling will be collected only for subjects enrolled in the study. If an historic specimen is not available, a 
fresh tumor biopsy must be performed, if considered safe by the Investigator. If safety concerns preclude collection of a biopsy during the screening period, a 
tumor biopsy specimen collected prior to the conclusion of the most recent anticancer treatment may be used. In the event a fresh biopsy needs to be scheduled, 
the site may consent the subject and schedule the screening visit assessments to be performed such that all assessments fall within 28 days prior to the first dose 
of any study medications. If safety concerns preclude collection of a biopsy during the screening period, a tumor biopsy specimen collected prior to the 
conclusion of the most recent anticancer treatment may be used. A tumor biopsy is also required 8 weeks after the start of treatment, if considered safe by the 
Investigator 
s Tumor imaging by CT scan, MRI, or PET-CT will be performed at screening and every 8 weeks thereafter in the induction phase. Evaluations may include CT, 
MRI, or PET-CT scans of the chest, abdomen, pelvis (optional unless known pelvic disease is present at screening), and brain (only as clinically warranted 
based on symptoms/findings). All screening tumor imaging assessments should be performed based on the subject's qualifying scan obtained within 28 days 
prior to the start of treatment. RECIST and irRC documentation to be completed at each assessment period. The same mode of imaging is required to be carried 
through each subject’s respective treatment period.

a Subjects will remain in 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. Any required blood draws and safety laboratory sample collections (including urinalysis) may be performed within a 3-day window of the 
time indicated.± 
b EOT visit must be performed 30 (±5 days) after the last study treatment. 
c Additional assessments performed during an unscheduled visit are at the discretion of the PI or treating physician and must be recorded in the subject’s source 
documents and on the Unscheduled Visit eCRF. 
d Vital signs of temperature, heart rate, blood pressure, and respiratory rate will be assessed at every visit. Vital signs are to be obtained after the subject has been 
in a seated resting position for at least 5 minutes and within 30 minutes prior to the start of any infusional study treatment. For visits where a subject is 
receiving an infusion of any study compounds, vital signs will be collected at the following time points in relation to the start of first infusion of the day: prior 
to infusion, 15 minutes post, 30 minutes post, and hourly until the subject is discharged. Temperature will be documented each visit at the first pre-infusion
