About
This phase I trial studies the side effects and the best dose of giving EGEN-001 together with pegylated liposomal doxorubicin hydrochloride in treating patients with ovarian epithelial, fallopian tube, or primary peritoneal cancer that has returned after a period of improvement or has not responded to treatment. Biological therapies, such as EGEN-001, may stimulate the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as pegylated liposomal doxorubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving EGEN-001 together with pegylated liposomal doxorubicin hydrochloride may kill more tumor cells.
Full description
PRIMARY OBJECTIVES:
I. To determine the maximum-tolerated dose (MTD) and dose-limiting toxicities (DLTs) of EGEN-001 when administered in combination with pegylated liposomal doxorubicin hydrochloride (PLD; Doxil; Lipodox) every 28 days and the associated DLTs based on adverse events that occur in cycle 1 for this combination in women with recurrent or persistent epithelial ovarian, fallopian tube, or primary peritoneal cancer.
II. To examine the tolerability of the combination at the MTD of EGEN-001 assessed in combination with PLD.
III. To determine recommended phase II dose (RP2D) of EGEN-001 in combination with PLD.
SECONDARY OBJECTIVES:
I. To estimate the objective response rate (complete and partial) in patients with measurable disease.
TERTIARY OBJECTIVES:
I. Determine the levels and time course of interleukin-12 (IL-12), interferon-gamma (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha) and vascular endothelial growth factor (VEGF) following EGEN-001 treatment.
II. Assess the effect of EGEN-001 treatment on the nature of the cellular immune responses by measuring cell-specific ribonucleic acid (RNA) transcripts.
OUTLINE: This is a dose-escalation study of EGEN-001.
Patients receive pegylated liposomal doxorubicin hydrochloride intravenously (IV) over 60 minutes on day 1 and EGEN-001 intraperitoneally (IP) over 30-60 minutes on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up quarterly for up to 1 year.

Inclusion criteria
Patients must have histologic diagnosis of epithelial ovarian, fallopian tube, or primary peritoneal carcinoma which is now persistent or recurrent; histologic documentation of the original primary tumor is required via the pathology report
Patients with the following histologic epithelial cell types are eligible: high-grade serous adenocarcinoma, endometrioid adenocarcinoma, undifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma, or adenocarcinoma not otherwise specified (N.O.S.)
Patients must have recurrence documented by elevated CA-125 (biochemical recurrence) or clinically evident measurable or non-measurable recurrent disease as defined below:
Biochemical recurrence is defined as a CA-125 greater than or equal to two times the upper normal limit; patients whose CA-125 is less than 100 U/mL must undergo a second confirmatory value within a period of not more than 4 weeks; patients with a level greater than or equal to 100 U/mL may be entered without confirmatory measurement; the CA-125 assessment for eligibility must be done at least 4 weeks after paracentesis or other surgical procedures
Detectable (non-measurable) disease is defined as symptomatic ascites or pleural effusions, solid and/or cystic abnormalities on radiographic imaging that do not meet RECIST 1.1 definitions for target lesions and/or biopsy-proven recurrence
Measurable disease will be defined by RECIST 1.1; measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded); each lesion must be ? 10 mm when measured by computed tomography (CT), magnetic resonance imaging (MRI), or caliper measurement by clinical exam; or ? 20 mm when measured by chest x-ray; lymph nodes must be ? 15 mm in short axis when measured by CT or MRI
Absolute neutrophil count (ANC) >= 1,500/mcl; this ANC cannot have been induced or supported by granulocyte colony-stimulating factors
Platelets >= 100,000/mcl
Creatinine =< 1.5 times institutional upper limit of normal (ULN)
Bilirubin =< 1.5 times ULN
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 3.0 x ULN
Alkaline phosphatase =< 2.5 x ULN
Left ventricular ejection fraction (LVEF) greater than or equal to institutional lower limit of normal (LLN) as determined by gated cardiac radionucleotide scan (multi-gated acquisition scan [MUGA]) or echocardiogram
Neuropathy (sensory and motor) less than or equal to grade 1
Patients must have recovered from effects of recent surgery, radiotherapy, or chemotherapy
Patients should be free of active infection requiring parenteral antibiotics
Any hormonal therapy directed at the malignant tumor must be discontinued at least one week prior to registration; continuation of hormone-replacement therapy is permitted
Any other prior therapy directed at the malignant tumor, including biological and immunologic agents, must be discontinued at least three weeks prior to registration
Patients must have had one prior platinum-based chemotherapeutic regimen for management of primary disease containing carboplatin, cisplatin, or another organoplatinum compound; this initial treatment may have included intraperitoneal therapy, consolidation, non-cytotoxic agents, or extended therapy administered after surgical or non-surgical assessment
Patients are allowed to receive, but are not required to receive, two additional cytotoxic regimens for management of recurrent or persistent disease, with no more than 1 non-platinum, non-taxane regimen
Prior treatment with pegylated liposomal doxorubicin hydrochloride [Doxil] or other anthracyclines is NOT allowed
Patients are allowed to receive, but are not required to receive, non-cytotoxic therapy (such as bevacizumab) as part of their primary treatment regimen
Patients who have received only one prior cytotoxic regimen (platinum-based regimen for management of primary disease), must have a platinum-free interval of less than 12 months, have progressed during platinum-based therapy, or have persistent disease after a platinum-based therapy
Gynecology Oncology Group (GOG) performance status of 0 or 1
Patients of childbearing potential must have a negative pregnancy test prior to the study entry and be practicing an effective form of contraception; if applicable, patients must discontinue breastfeeding prior to study entry
Patients who have met the pre-entry requirements
Patients must have signed an Institutional Review Board (IRB)-approved informed consent and authorization permitting release of personal health information
