A Phase 1/2, Open-Label Study of ADXS-503 Alone and in Combination With Pembrolizumab in Subjects With Metastatic Squamous or Non-Squamous Non-Small Cell Lung Cancer

A Phase 1/2, Open-Label Study of ADXS-503 Alone and in Combination with Pembrolizumab in
Subjects with Metastatic Squamous or Non-Squamous Non-Small Cell Lung Cancer

To evaluate the safety and tolerability of ADXS-503, administered as monotherapy in Part A
and in combination with pembrolizumab in Part B, and to determine the maximum tolerated dose
(MTD) or maximum administered dose (MAD). As well, to characterize the preliminary anti-tumor
activity of ADXS-503, administered in combination with pembrolizumab in Part C, per RECIST
v1.1.

Inclusion Criteria:

1. Subject and/or their legally authorized representative must be capable of
understanding the investigational nature, potential risks, and benefits of the study.
The subject and/or their legally authorized representative must sign a written
informed consent;

2. Subject is ≥18 years of age upon signing the Informed Consent Form;

3. Subject has histologically or cytologically confirmed stage IV (metastatic) squamous
or non-squamous NSCLC

- Part A only:

▪ Subject has received, and then progressed or been intolerant to up to 3 lines
of prior therapy in the metastatic setting, including approved chemotherapy,
targeted therapy, immunotherapy and antibody therapy, if eligible. Subjects who
have received >3 lines of prior therapy may be eligible for Part A, upon
discussion with and approval by the Sponsor.

- Subjects will be eligible for Part A irrespective of PD-L1 expression.

- Subjects will be eligible for Part A irrespective of EGFR or ALK mutation
status. However, subjects with an EGFR sensitizing mutation or ALK
translocation must have received and then progressed or been intolerant to
at least 1 prior line of approved targeted therapy to be eligible for Part
A.

- Part B only:

- Subject is undergoing treatment with pembrolizumab monotherapy for
metastatic NSCLC

- Subject's most recent tumor assessment is consistent with PD according to
RECIST v1.1

- The Investigator has determined that PD should be confirmed within 4-8
weeks, and pembrolizumab treatment will continue pending PD confirmation

- Subject is willing to undergo a confirmatory scan 4-8 weeks from the prior
scan that indicated progression on pembrolizumab

- There is no evidence of rapid disease progression or clinical deterioration
in the subject that would preclude continuation of pembrolizumab treatment
pending confirmation of PD.

- Part C only:

- Subject has received no prior systemic treatment in the metastatic setting.
Subjects previously treated with adjuvant or neoadjuvant therapy are
eligible if the adjuvant/neoadjuvant therapy was completed at least 6 months
prior to the diagnosis of metastatic disease.

- Subject has provided a formalin-fixed tumor sample from a biopsy of a tumor
lesion either at the time of or after the diagnosis of metastatic disease
AND from a site not previously irradiated, to assess for PD-L1 status.
Biopsies obtained PRIOR to the administration of any systemic therapy to
treat the subject's tumor (such as neoadjuvant/adjuvant therapy) will not be
permitted for analysis. The tissue sample must be received by the central
laboratory vendor prior to enrollment. Fine needle aspirates, Endobronchial
Ultrasound (EBUS) or cell blocks are not acceptable. Needle or excisional
biopsies, or resected tissue is required. If the tumor specimen is not
evaluable for PD-L1 expression by the central laboratory, an additional
tumor specimen may be submitted.

- Subject's tumor has PD-L1 expression of ≥50%, as determined by
immunohistochemistry (IHC) at a central laboratory.

- Subject's tumor does not harbour an EGFR sensitizing (activating) mutation
or ALK translocation. EGFR sensitizing mutations are mutations that are
amenable to treatment with TKIs (e.g., erlotinib, gefitinib, afatanib,
osimertinib). ALK translocations are amendable to treatment with TKIs such
as crizotinib, alectinib and ceritinib. Investigators must produce the
source documentation of the EGFR mutation and ALK translocation status in
all subjects with non-squamous histology AND for subjects in whom testing is
clinically indicated. If either an EGFR sensitizing mutation or ALK
translocation is detected, additional information regarding the mutation
status of the other molecule is not required. If the clinical site is unable
to provide the source documentation, EGFR and ALK testing should be
performed per institutional standard of care.

4. Subject has measurable disease for response assessment as defined by RECIST v1.1 by
the Investigator;

5. Subject has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1
(see Appendix 11);

6. Subject has a life expectancy of at least 3 months;

Criteria for Adverse Events, Version 4.03 (NCI-CTCAE v4.03) of all clinically
significant toxic effects of prior anti-cancer chemotherapy, immunotherapy,
radiotherapy or surgery before entering this study, except for alopecia;

8. Subject has no major existing comorbidities or medical conditions that would preclude
therapy in the opinion of the Investigator;

9. Subject has adequate organ function

10. A female subject is eligible to participate if she is not pregnant (see Appendix 5),
not breastfeeding, and at least one of the following conditions applies:

1. Not a woman of childbearing potential (WOCBP) as defined in Appendix 5 OR

2. A WOCBP who agrees to follow the contraceptive guidance in Appendix 5 during the
treatment period and for at least 120 days after the final dose of study
treatment;

11. A female subject of childbearing potential must have a negative urine or serum
pregnancy test within 72 hours prior to receiving the first dose of study treatment
and throughout the study as defined in the SoA. If the urine test is positive or
cannot be confirmed as negative, a serum pregnancy test will be required.

12. A male subject is eligible if he agrees to follow the contraceptive guidance in
Appendix 5 during the treatment period and for at least 120 days after the final dose
of study treatment.
