Eligibility
Key inclusion criteria
Inclusion Criteria for Cohort A: Subjects who meet all of the following criteria will be
eligible to participate in Cohort A of the study:

1. Have initiated first-line therapy for NSCLC with pembrolizumab and satisfy the
following:

- Have tumor PD-L1 =1% by 22C3 IHC;

- Are judged by the Principal Investigator as tolerating pembrolizumab monotherapy; and

- Have been on pembrolizumab for at least 3 months (measured from actual first dose date
to first dose date of the current study) and the most recent scans are the first scans
to objectively demonstrate Progressive Disease per RECIST 1.1

- The first scan conducted a minimum of 21 days after first dose of anti-PD-(L)1 therapy
must have shown either SD, PR, or CR (ie, not Progressive Disease) per RECIST 1.1; and

- The 2 most recent scans (including 1 demonstrating Progressive Disease) are available
to be reviewed

Inclusion Criterion for Cohort B

Subjects who meet the following criterion will be eligible to participate in Cohort B of
the study:

1. Are eligible for single-agent pembrolizumab for advanced/metastatic NSCLC in accordance
with the package insert and have tumor PD-L1 =50% by 22C3 IHC

• Must not have been treated previously with platinum-based chemotherapy in the
advanced/metastatic setting. Note: Subjects may have received chemotherapy and/or anti PD
(L)1 therapy in the neo/adjuvant setting, provided the last dose of therapy was >9 months
prior to randomization.

All cohorts require PD-L1 testing (TPS as determined by an FDA-approved test: subjects in
Cohort B must specifically have PD-L1 testing using the PD-L1 IHC 22C3 pharmDx test kit).
Subjects in Cohort B for whom PD-L1 testing was not performed with the required IHC 22C3
pharmDx test kit may be randomized if all other study criteria have been met, pending
retest with the required IHC 22C3 pharmDx test kit.

Subjects who meet the following criterion will be eligible to participate in Cohort C of
the study:

1. Have initiated IL therapy for NSCLC and completed all planned (eg, 4 to 6 cycles)
platinum-based chemotherapy with at least 2 cycles in combination with pembrolizumab; must
not have had progressive disease on tumor staging imaging scans following completion of all
planned platinum chemotherapy

- Are eligible for maintenance therapy with pembrolizumab ± pemetrexed in accordance
with the package insert

- Have tumor PD-L1 =1%

- The last dose of platinum-based chemotherapy must be within 8 weeks of the first dose
of the study drug in this study

Inclusion Criterion for All Cohorts

- Subjects must also meet all of the following criteria to be eligible to participate in
the study:

1. Have histologically confirmed NSCLC that is inoperable, locally advanced or
metastatic (Stage IIIb/IV)

2. Have available at the site a representative formalin-fixed, paraffin-embedded
tumor specimen that enabled diagnosis of NSCLC in a tissue block (preferred) or
10 unstained, serial slides, accompanied by an associated pathology report. Note:
If the archival tissue is neither sufficient nor available, the subject may still
be eligible, upon discussion with the Medical Monitor

3. Have provided written informed consent and any authorizations required by local
law

4. Are =18 years of age

5. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Have NSCLC with epidermal growth factor receptor or anaplastic lymphoma kinase genomic
tumor aberrations

2. Have gastrointestinal (GI) disease (eg, gastric or intestinal bypass surgery,
pancreatic enzyme insufficiency, malabsorption syndrome, symptomatic inflammatory
bowel disease, chronic diarrheal illness, and/or bowel obstruction) that may interfere
with drug absorption or with interpretation of GI AEs

3. Have known symptomatic brain metastases requiring >10 mg/day of prednisone (or its
equivalent). Subjects with previously diagnosed brain metastases are eligible if they
have completed their treatment, have recovered from the acute effects of radiation
therapy or surgery prior to randomization, fulfill the steroid requirement for these
metastases, the 2 most recent serial magnetic resonance imaging (MRI) scans conducted
>28 days apart show no central nervous system progression, and are neurologically
stable and asymptomatic
