Study Details

Study Description

Brief Summary

The investigators hypothesize that tumor cell killing by cytotoxic chemotherapy exposes the immune system to high levels of tumor antigens.The combination of Paclitaxel/Carboplatin and Pembrolizumab may result in deeper and more durable responses compared with standard chemotherapy alone.

Outcome Measures

Primary Outcome Measures

Pathologic Objective Response Rate (pORR) in Participants Receiving Protocol Therapy [up to 48 months]
Measure of pathologic response

Secondary Outcome Measures

Progression-Free Survival (PFS) Rate in Participants Receiving Protocol Therapy [Up to 48 months]
Rate of Progression-Free Survival (PFS) in participants receiving protocol therapy. PFS is defined as the length of time from the date of first dose of study treatment until date of disease progression or death due to any cause, whichever comes first.
Rate of toxicity in participants [Up to 48 Months]
Safety and tolerability of the intervention will be reported as the rate of toxicity in participants as assessed by treating physician

Accepts Healthy Volunteers:

Inclusion Criteria:

No prior treatment for primary advanced (Stage III or IV) high grade epithelial ovarian, primary peritoneal, or fallopian tube carcinoma such as irradiation, chemotherapy, hormonal therapy, immunotherapy, investigational therapy, and/or other concurrent agents or therapies.
Patients must undergo diagnostic laparoscopy for disease assessment for tissue biopsies to confirm diagnosis with planned interval tumor reductive surgery after completion of 3-4 cycles of treatment. For those not medically fit to undergo laparoscopy, as determined by the Investigator. (interventional radiology) IR-guided core biopsies may be used.
Patients must be appropriate candidates for planned neoadjuvant chemotherapy (NACT) with combination carboplatin and paclitaxel given intravenously (IV) every 3 weeks ( IV Q3W).
Tissue from an archival sample or newly obtained core or excisional biopsy of a tumor lesion.
Age ≥ 18 years.
Life expectancy > 3 months.
Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.
Patients must have normal organ and marrow function as defined below:

Hematologic
Absolute neutrophil count (ANC) ≥1,500 /microliter (mcL).
Platelets ≥ 100,000 / mcL.
Hemoglobin ≥ 9 g/dL or ≥ 5.6 mmol/L without transfusion or Erythropoietin (EPO) dependency
Renal
Serum creatinine ≤ 1.5 X upper limit of normal (ULN) OR
Measured or calculated a creatinine clearance ≥60 mL/min for subject with creatinine levels > 1.5 X institutional ULN (GFR can also be used in place of creatinine or CrCl). Creatinine clearance should be calculated per institutional standard.
Hepatic
Serum total bilirubin ≤ 1.5 X ULN OR
Direct bilirubin ≤ ULN for subjects with total bilirubin levels > 1.5 ULN
Aspartate transaminase (AST/SGOT) and Alanine transaminase (ALT/SGPT) ≤ 2.5 X ULN OR ≤ 5 X ULN for subjects with liver metastases.
Albumin > 2.5 mg/dL
Coagulation
International Normalized Ratio (INR) or Prothrombin Time (PT) ≤ 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
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.

Negative urine or serum pregnancy ≤ 72 hours (i.e. 3 days) prior to receiving the first dose of study medication if not surgically sterilized. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
Female subjects of childbearing potential (have not been surgically sterilized or have not been without menses for > 1 year) should be willing to use 2 methods of birth control at the same time or be surgically sterile, or abstain from heterosexual activity for the course of the study and at least 120 days after the last study dose.

Exclusion Criteria:

Patients who are currently in or have participated in a study of an investigational agent or used an investigational device within 4 weeks of the first dose of treatment.
Histology showing mucinous or low grade epithelial ovarian cancer.
Patients who will not be likely to undergo IDS either secondary to performance status or sites of disease. If at the time of surgery, the patient is deemed to be surgically resectable to no gross residual, the patient will not be eligible for the study.
Patients with known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least 4 weeks prior to the first dose of study treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 28 days prior to study treatment.
Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy.
Has received prior therapy with an anti-PD1, anti-PDL1, anti-CD137, anti-cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways) or anti-PDL2 agent.
Uncontrolled intercurrent illness including but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
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 study treatment.
Prior monoclonal antibody within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.
Prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1 or has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to previously administered event. Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for this study. If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
Has active autoimmune disease that has required systemic treatment in the past two years (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (i.e., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
Evidence of interstitial lung disease or active, non-infectious pneumonitis.
Is pregnant or breastfeeding or expecting to conceive within the projected duration of the study, starting with the pre-screening or screening visit through 120 days after the last dose of study treatment.

Received live vaccine within 30 days prior to the first dose of study treatment. Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however, intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines and are not allowed.
Patient has active bacillus tuberculosis (TB).

Patient receiving concurrent additional biologic therapy.
Any other serious medical or psychiatric illness/condition likely in the judgment of the Investigator(s) to interfere or limit compliance with study requirements/treatment.
