A Phase 2 Multicenter, Randomized, Placebo Controlled, Double-Blind Study To Assess The Safety And Efficacy Of CC-486 (Oral Azacitidine) In Combination With Pembrolizumab (MK-3475) Versus Pembrolizumab Plus Placebo In Subjects With Previously Treated Locally Advanced Or Metastatic Non-Small Cell Lung Cancer

The purpose of this study is to determine whether the combination therapy of CC-486 (oral
azacitidine) and pembrolizumab provides improved patient outcomes compared to pembrolizumab
alone in patients with previously treated locally advanced or metastatic non-small cell lung
cancer.

This is a Phase 2, multicenter, international, randomized, placebo controlled, double-blind
study to assess the safety and efficacy of CC-486 and pembrolizumab combination therapy
versus pembrolizumab plus placebo in previously treated patients with locally advanced or
metastatic non-small cell lung cancer (NSCLC) who had received one prior platinum-based
chemotherapy regimen.

Approximately 100 participants will be randomized 1:1 to receive CC-486 plus pembrolizumab or
placebo plus pembrolizumab as follows:

- Arm A: CC-486 300 mg administered orally daily on days 1 to 14 plus pembrolizumab 200 mg
administered as a 30-minute IV infusion on day 1 of a 21-day cycle

- Arm B: Placebo administered orally daily on days 1-14 plus pembrolizumab 200 mg
administered as a 30-minute IV infusion on day 1 of a 21-day cycle

Randomization will be stratified between treatment arms by histology (non-squamous versus
squamous).

The decision to discontinue a patient, which will not be delayed or refused by the Sponsor,
remains the responsibility of the treating physician. However, prior to discontinuing a
patient, the Investigator may contact the medical monitor and forward appropriate supporting
documents for review and discussion.

In the follow-up phase, anticancer treatment administered following the last dose of
investigational product (IP) and survival will be followed every 8 weeks until death,
withdrawal of consent, or lost-to follow-up, whichever occurs first, or the End of Trial.

The study will be conducted in compliance with the International Council on Harmonisation
(ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use/Good
Clinical Practice (GCP) and applicable regulatory requirements.

Primary analysis will be conducted when 70 Progression Free Survival (PFS) events have
occurred.

Inclusion Criteria:

1. Participant is ≥ 18 years of age at the time of signing the informed consent form.

2. Participant has histologically or cytologically confirmed squamous or non-squamous
non-small cell lung cancer (NSCLC).

Staging Manual, 7th edition [Edge, 2009]) and was pretreated with only 1 prior
systemic platinum based chemotherapy.

4. Participant has provided a formalin fixed tumor tissue sample from a biopsy of a tumor
lesion either at the time of or after the diagnosis of metastatic disease has been

ultrasound (EBUS) or cell blocks are not acceptable. Needle or excisional biopsies, or
resected tissue is required. Archival tissue may be acceptable. Submission of
formalin-fixed paraffin embedded tumor tissue sample blocks are preferred; if
submitting unstained slides, the slides should be freshly cut and submitted to the
testing laboratory within 14 days from site slide sectioning date otherwise a new
specimen will be requested.

starting study therapy. She must agree to ongoing pregnancy testing during the
course of the study, and after end of study treatment. This applies even if the
participant practices true abstinence* from heterosexual contact.

reviewed on a monthly basis) or agree to use, and be able to comply with two
effective methods of contraception without interruption, 28 days prior to
starting IP, during the study therapy (including dose interruptions), and for 120
days after discontinuation (or longer if required by local requirements) of study
therapy. The two methods of contraception can either be two barrier methods or a
barrier method plus a hormonal method to prevent pregnancy.

10. Male participants must practice true abstinence* (which must be reviewed on a monthly
basis) or agree to the use a condom during sexual contact with a pregnant female or a
female of childbearing potential while participating in the study, during dose
interruptions and for at least 3 months following investigational product
discontinuation (or longer if required by local requirements), even if he has
undergone a successful vasectomy.

* True abstinence is acceptable when this is in line with the preferred and usual
lifestyle of the participant. Note: Periodic abstinence (eg, calendar, ovulation,
symptothermal, postovulation methods) and withdrawal are not acceptable methods of
contraception.
