Brief Summary
This study is phase II, open label, clinical trial to determine the efficacy of Oregovomab and non-platinum chemotherapy in PARP inhibitor resistant ovarian, fallopian tube, or primary peritoneal cancer patients who were not suitable for platinum retreatment. Patients who have received one to three prior lines of chemotherapy are to be assigned to Cohort 1 (oregovamab 2 mg \[C1,2,3,5,7 for five doses\] + pegylated liposomal doxorubicin \[PLD\] 40 mg/m2 q4w, n=28), while patients who have received more than three prior lines of chemotherapy are to be assigned to Cohort 2 (oregovamab 2 mg \[C1,2,3,5,7 for five doses\] + weekly paclitaxel 80 mg/m2 \[D1,8,15 q4w\], n=28). A total of 56 patients will be recruited and treated with oregovomab + PLD / weekly paclitaxel until disease progression, unacceptable toxicity, or withdrawal of patient consent. The primary endpoint is objective response rate by RECIST 1.1.

Study Arms (2)
Cohort 1(1-3 prior line of chemotherapy)
EXPERIMENTALOregovomab and PLD is synergistic in PARPi-resistant recurrent ovarian cancer.
Cohort2 (>3prior line of chemotherapy)
EXPERIMENTALOregovomab and Paclitaxel show synergistic in PARPi-resistant recurrent ovarian cancer.
Interventions
PLD (40 mg / m2 IV over three hours in one day) to be repeated till progression or unacceptable toxicity every four weeks (28 days) Investigational agent (Oregovomab): 2 mg diluted in 50 mL saline for injection administered IV following PLD over approximately 20 (acceptable range 15-30) minutes for a total of 5 scheduled injections, one each at Cycle 1, Cycle 2, Cycle 3, Cycle 5, and Cycle 7
paclitaxel (80 mg / m2 IV over three hours in one day) to be repeated till progression or unacceptable toxicity every four weeks on day 1, 8, 15 Investigational agent (Oregovomab): 2 mg diluted in 50 mL saline for injection administered IV following paclitaxel over approximately 20 (acceptable range 15-30) minutes for a total of 5 scheduled injections, one each at Cycle 1, Cycle 2, Cycle 3, Cycle 5, and Cycle 7
Eligibility Criteria
You may qualify if:
- Adults 20 years old or older.
- Subjects with histologically confirmed epithelial adenocarcinoma of ovarian, fallopian tube or peritoneal origin.
- Eligible histologic epithelial cell types: high grade serous adenocarcinoma, high grade endometrioid adenocarcinoma, undifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma, , and low-grade adenocarcinoma, or adenocarcinoma not otherwise specified (N.O.S.).
- \[only up to 5 patients with non-high grade serous carcinoma will be included\]
- Prior PARP inhibitor exposure (progressed through a prior PARP inhibitor)
- CA-125 ≥ 50 U/ml
- Prior platinum-based chemotherapy.
- Cohort 1 : 1-3 prior lines of therapies / Cohort 2 : Previous treatments of the 4th line or more.
- Not eligible for platinum re-treatment (prior allergic reaction or residual toxicity, patients who are not able to receive (in the physician's opinion) or willing to receive platinum treatment and platinum resistant patients)
- Received prior bevacizumab or not eligible for bevacizumab due to medical.
- Adequate bone marrow function:
- Absolute neutrophil count (ANC) ≥ 1,500/μL
- Platelets ≥ 100,000/μL
- Hemoglobin ≥ 8.0 g/dL (Note: Blood transfusion is permitted up to 48 hours before first dose of study treatment).
- Adequate liver function:
- +7 more criteria
You may not qualify if:
- Participant has mucinous, germ cell, or borderline tumor of the ovary.
- Female subjects who are lactating and breastfeeding, or have a positive serum pregnancy test within 7 days prior to the first dose of study treatment.
- Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol.
- Active autoimmune disease, such as rheumatoid arthritis, systemic lupus erythematosus (SLE), ulcerative colitis, Crohn's Disease, multiple sclerosis (MS), or ankylosing spondylitis requiring active disease modifying treatment.
- Known allergy to murine proteins or hypersensitivity to any of the excipients of the oregovomab and PLD.
- Chronically treated with immunosuppressive drugs such as cyclosporine, adrenocorticotropic hormone (ACTH), etc.
- Chronic therapeutic corticosteroid use, defined as \> 5 days of prednisone or equivalent, with the exception of inhalers or those on a pre-planned steroid taper.
- Recognized acquired, hereditary, or congenital immunodeficiency disease, including cellular immunodeficiencies, hypogammaglobulinemia or dysgammaglobulinemia.
- Clinically significant active infection(s) at the time of screening.
- Any of the following conditions (on-study testing is not required):
- Known HIV-infected subjects unless on effective anti-retroviral therapy with an undetectable viral load within 6 months, or
- Known or suspected hepatitis C infection which has not been treated and cured unless currently on treatment with an undetectable viral load).
- Uncontrolled or life-threatening diseases compromising safety evaluation.
- Participant has a known additional malignancy that is progressing or has required active treatment within the past 2 years.
- Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g. breast carcinoma, cervical cancer in situ, endometrial carcinoma) that have undergone potentially curative therapy are not excluded.
