An Open Label Phase II Trial of Guadecitabine and Pembrolizumab in Platinum Resistant Recurrent Ovarian Cancer

The purpose of this study is to look at how patients respond to treatment with guadecitabine
and pembrolizumab. The researchers will also be looking at the amount of time it takes for
cancer to get worse when participants take the study drugs. All participants will be treated
with guadecitabine and pembrolizumab. Guadecitabine interferes with the cancer cells' DNA and
can increase the production of certain proteins, making cancer cells more recognizable by the
immune system. Pembrolizumab helps your immune system to kill cancer cells. Thus the
combination of guadecitabine and pembrolizumab may increase the ability of the immune system
to eliminate cancer cells. Researchers want to find out whether the combination of
guadecitabine and pembrolizumab is effective in treating ovarian cancer that has not
responded to traditional chemotherapy. Participants will keep receiving treatment until their
cancer gets worse, they have side effects, or they decide they don't want to receive the
treatment anymore. After stopping treatment, the study doctor will watch participants for
side effects and follow their condition every 6-12 weeks. The study aims to keep track of
participants' medical conditions for the rest of their lives. This helps us look at the
long-term effects of the study drugs.

PRIMARY OBJECTIVES:

I. Measure objective response rate (RR) to guadecitabine and pembrolizumab in subjects with
recurrent platinum resistant ovarian cancer (OC).

SECONDARY OBJECTIVES:

I. Measure progression free survival (PFS) for the combination of guadecitabine and
pembrolizumab.

II. Progression free survival (PFS). III. Measure clinical benefit rate (CBR) for the
combination of guadecitabine and pembrolizumab.

IV. Measure toxicity profiles to the combination of guadecitabine and pembrolizumab.

TERTIARY OBJECTIVES:

I. NY-ESO-1 and MAGE antigens' promoter methylation (pyrosequencing) and messenger
ribonucleic acid (mRNA) expression levels (quantitative reverse transcriptase-polymerase
chain reaction [RT-PCR]) will be measured before and after treatment in deoxyribonucleic acid
(DNA) (plasma and/or tumor biopsies) and ribonucleic acid (RNA) (tumor biopsies),
respectively.

II. Cytokine response (IFN gamma IL2, IL6, IL10, TNF alpha) will be measured in plasma by
enzyme-linked immunosorbent assay (ELISA).

III. Measure LINE 1 methylation in DNA extracted from peripheral blood mononuclear cells
(PBMCs) (measured on days 1 and 5 of cycles 1 and 2).

IV. Expression of the PD-L1 ligand will be measured by immunohistochemistry (IHC) in archival
tumors.

V. Tumor infiltrating lymphocytes (TILs) will be quantified in tumor biopsies before and
after treatment (IHC).

OUTLINE:

Patients receive guadecitabine subcutaneously (SC) on days 1-4 and pembrolizumab
intravenously (IV) over 30 minutes on day 5. Courses repeat every 21 days in the absence of
disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, every 6 weeks for 1
year, and then every 9 weeks and, once a subject experiences confirmed disease progression or
starts a new anticancer therapy, every 3 months thereafter.

Inclusion Criteria:

support/erythropoietin [EPO] dependency)

creatinine or creatinine clearance [CrCl]) >= 60 mL/min for subject with creatinine
levels > 1.5 X institutional ULN

- Serum total bilirubin =< 1.5 X ULN OR direct bilirubin =< ULN for subjects with total
bilirubin levels > 1.5 ULN

- Albumin >= 2.5 mg/dL

- International normalized ratio (INR) or prothrombin time (PT) =< 1.5 X ULN unless
subject is receiving anticoagulant therapy as long as PT or partial thromboplastin
time (PTT) is within therapeutic range of intended use of anticoagulants

- Activated partial thromboplastin time (aPTT) =< 1.5 X ULN unless subject is receiving
anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use
of anticoagulants

- Be willing to allow the use of archival formalin-fixed paraffin-embedded tumor tissue
for correlative analyses

- Note: The archived tumor tissue specimens may be from prior surgery or from prior
diagnostic biopsy of primary or metastatic tumor specimen; unavailability of
archived tissue will not render subject ineligible for study

institutional standards (guided visually or by computed tomography [CT] or
ultrasound), paracentesis, or thoracentesis for tumor cells

- Note: This is to be done prior to treatment at cycle 1 day 1 (C1D1) and
post-treatment (cycle 2 day 8), if this is clinically and safely feasible to do
so; this will allow the use of this freshly obtained tissue for correlative
analyses in the study

following completion of therapy; should a female patient become pregnant or suspect
she is pregnant while participating in this study, she should inform her treating
physician immediately

tubal ligation, or remaining celibate by choice) who meets the following
criteria:
