About this trial
This is an interventional treatment trial for Platinum-resistant Ovarian Cancer focused on measuring olvimulogene nanivacirepvec, GL-ONC1, GLV-1h68, oncolytic virus, virotherapy, viral therapy, immunotherapy, immunochemotherapy, combination therapy, vaccinia virus, ovarian cancer, fallopian tube cancer, primary peritoneal cancer, platinum resistant, platinum refractory, recurrent ovarian cancer
Eligibility Criteria
Inclusion Criteria:
- Histologically confirmed (from prior treatment) non-resectable ovarian, fallopian tube or primary peritoneal cancer.
- High-grade serous [including malignant mixed Mullerian tumor (MMMT) with metastasis that contains high-grade epithelial carcinoma, FIGO grades 2 & 3 allowed], endometrioid, or clear-cell ovarian cancer.
- Performance status ECOG of 0 or 1.
- Life expectancy of at least 6 months.
- Received a minimum of 3 prior lines (including the 1st line) of systemic therapy with no maximal limit.
- Time from Last Platinum of 3-15 months since the last dose of platinum in the most recent platinum-based line of therapy (excluding using platinum as a radiosensitizer) until consent into this trial.
- Platinum-resistant or -refractory disease based on platinum-free interval (PFI) from the last dose of the most recent. platinum-based line of therapy (must have received a minimum of 2 doses of platinum in that line) to subsequent disease progression based on radiological assessment. Platinum-refractory: PFI of < 1 month (including disease progression while on platinum-based therapy). Platinum-resistant: PFI of 1-6 months.
- Received prior bevacizumab (or biosimilar) treatment.
- No contraindication to receive carboplatin, cisplatin or bevacizumab (or biosimilar).
- Have disease progression after last prior line of therapy based on radiological assessment prior to randomization.
- At least 1 measurable target lesion per RECIST 1.1 based on abdominal/pelvis imaging scan at screening.
- Evidence by CT and/or PET scans or physical exam of abdominal/pelvis region likely having disease in the peritoneal cavity (i.e., peritoneal carcinomatosis).
- Adequate renal, hepatic, bone marrow function, adequate coagulation tests, adequate immune function by lymphocyte count.
Exclusion Criteria:
- Tumors of mucinous, low-grade serous, squamous cell, small cell neuroendocrine subtypes, MMMT tumors absent an epithelial component on recent biopsy, or non-epithelial ovarian cancers (e.g., germ cell tumors, Sex-cord tumors).
- Bowel obstruction within last 3 months prior to screening.
- Active urinary tract infection, pneumonia, other systemic infections.
- Active gastrointestinal bleeding.
- Known current central nervous system (CNS) metastasis.
- Inflammatory diseases of the bowel.
- History of HIV infection.
- Active hepatitis B virus or hepatitis C virus within 4 weeks prior to study.
- History of thromboembolic event within the prior 3 months.
- Contraindications for intraperitoneal (IP) catheter placement: Bowel obstruction with distended abdomen, rigid abdomen with bulky anterior wall carcinomatosis, abdominal wall hernia mesh that precludes laparoscopic entry to abdomen.
- Clinically significant cardiac disease at screening (New York Heart Association Class III/IV).
- Acute cerebrovascular event(s) such as cerebrovascular accident (CVA) or transient ischemic attack (TIA) in previous 6 months.
- Oxygen saturation <90%.
- Received prior virus-based gene therapy or therapy with cytolytic virus of any type.
- Receiving concurrent antiviral agent.
- Prior malignancy of other histology active within previous 3 years except for locally curable cancers apparently cured such as basal/squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of cervix or breast, any other stage I/II local malignancies.
- Received chemotherapy, radiotherapy, other anti-cancer biologic therapies within 4 weeks prior to planned treatment.
- Underwent surgery within 4 weeks, or have insufficient recovery from surgical-related trauma or wound healing, prior to first study treatment in either Arm.
- Receiving immunosuppressive therapy or steroids (except acute concurrent corticosteroid of no more than 20 mg per day for medical management with prednisolone equivalent.
- Symptomatic malignant ascites or pleural effusions defined as rapidly progressive ascites with abdominal distension and gastrointestinal dysfunction, pleural effusions with respiratory difficulties requiring frequent paracentesis > once every 14 days.
- Known hypersensitivity to gentamicin.
