APL-2 and Pembrolizumab Versus APL-2, Pembrolizumab and Bevacizumab Versus Bevacizumab Alone for the Treatment of Recurrent Ovarian, Fallopian Tube, or Primary Peritoneal Cancer and Malignant Effusion

Participant gender:
Female
Summary
This phase II trial studies the effect of APL-2 when given in combination with either pembrolizumab or pembrolizumab and bevacizumab compared with bevacizumab alone in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent) and a buildup of fluid and cancer cells (malignant effusion). APL-2 may limit tumor progression, decrease malignant effusion production, and improve the immune system's response against cancer cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving APL-2 together with either pembrolizumab or pembrolizumab and bevacizumab may work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer and malignant effusion compared to bevacizumab alone.

Criteria
Inclusion Criteria:

- Age >= 18 years of age on day of signing informed consent

- Recurrent epithelial ovarian/fallopian tube or primary peritoneal cancer (serous,
clear cell, endometrioid, mixed or poorly differentiated or carcinosarcoma) based on
imaging or synchronous primary ovarian and uterine cancer patients with any of the
histology subtypes mentioned above regardless of platinum sensitivity, prior stage or
number of prior treatment lines

- Symptomatic ascites or pleural effusion or both requiring >= 1 drainage within 4-weeks
of study entry or has a peritoneal/pleural drainage catheter in place to control
symptoms

- Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1

- Patient has not received pembrolizumab or other immune checkpoint inhibitor treatment
for 9 weeks prior to enrollment

- Life expectancy of >= 3 months

- Absolute neutrophil count (ANC): >= 1,500/µL

- Platelets: >= 75,000/µL

- Hemoglobin: >= 9 g/dL or 5.6 mmol/L (within 7 days of assessment)

- Creatinine: =< 1.5 X upper limit of normal (ULN) OR measured or calculated creatinine
clearance >= 60 mL/min (Cockcroft-Gault Equation) for participant with creatinine
levels > 1.5 X institutional ULN. GFR can also be used in place of creatinine or
creatinine clearance (CrCl)

- Total bilirubin: =< 1.5 X ULN OR direct bilirubin =< ULN for participants with total
bilirubin levels > 1.5 ULN

- Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase [SGOT]) and
alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]): =< 2.5 X
ULN OR =< 5 X ULN for participants with liver metastases

- Albumin: > 2.5 gm/dL

- International Normalized Ratio (INR) or Prothrombin Time (PT): =< 1.5 unless
participant is receiving anticoagulant therapy as long as PT or activated partial
thromboplastin time (aPTT) is within therapeutic range of intended use of
anticoagulants

- Activated Partial Thromboplastin Time (aPTT): =< 1.5 X ULN unless participant is
receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of
intended use of anticoagulants

- A woman of childbearing potential must have a negative urine or serum pregnancy within
72 hours prior to receiving the first dose of study medication. If the urine test is
positive or cannot be confirmed as negative, a serum pregnancy test will be required

- Participants of childbearing potential must be willing to use 2 methods of birth
control or be surgically sterile or abstain from heterosexual activity for the course
of the study through 120 days after the last dose of study medication (participants of
childbearing potential are those who have not been surgically sterilized or have not
been free from menses for > 1 year). Should a woman become pregnant or suspect she is
pregnant while she is participating in this study, she should inform her treating
physician immediately

- Willing and able to self-administer APL-2 (administration by caregiver will be
allowed)

- No known absolute contraindication to bevacizumab and/or pembrolizumab treatment per
enrolling provider

- Willing to receive vaccination against Neisseria meningitidis, Streptococcus
pneumoniae, and Hemophilus influenzae if randomized into an APL-2 receiving arm, if
not already vaccinated

- Participant must understand the investigational nature of this study and sign an
Independent Ethics Committee/Institutional Review Board approved written informed
consent form prior to receiving any study related procedure

Exclusion Criteria:

- Is currently receiving any additional cancer therapy or participating or used an
investigational drug or device within 3 weeks of the first dose of treatment

- Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any
other form of immunosuppressive therapy within 7 days prior to the first dose of trial
treatment or, is taking any other medication that might affect immune function

- Has active autoimmune disease that has required systemic treatment in the past 3
months (i.e. with use of disease modifying agents, corticosteroids or
immunosuppressive drugs). Replacement therapy (e.g. thyroxine, insulin, or physiologic
corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not
considered a form of systemic treatment

- Has an active infection requiring systemic therapy

- Has a history or current evidence of any condition, therapy, or laboratory abnormality
that might confound the results of the trial, interfere with the participant's
participation for the full duration of the trial, or is not in the best interest of
the patient to participate, in the opinion of the treating investigator

- Participant has clinically significant cardiovascular disease including:

- Uncontrolled hypertension, defined as systolic >150 mmHg or diastolic >90 mmHg

- Myocardial infarction or unstable angina within 6 months prior to enrollment

- Participant has a Grade II (NYHA) or greater peripheral vascular disease

- Participant has a clinically significant peripheral artery disease (e.g. those
with claudication), within 6 months prior to study enrollment

- Pregnancy or lactation

- Any condition which in the investigator's opinion deems the participant an unsuitable
candidate to receive study drug

- Has a history of (non-infectious) pneumonitis/interstitial lung disease that required
steroids or has current pneumonitis/interstitial lung disease.

emergency use). Note: Any licensed COVID-19 vaccine (including for Emergency Use) is
allowed in the study as long as they are modified ribonucleic acid (mRNA) vaccines,
adenoviral vaccines, or inactivated vaccines. These vaccines will be treated just as

approved for emergency use) are not allowed
