Brief Summary
The OnPrime study is a multi-center, randomized open-label phase 3 study evaluating the safety and efficacy of Olvi-Vec followed by platinum-doublet chemotherapy and bevacizumab compared to the Active...
Detailed Description
Olvi-Vec (olvimulogene nanivacirepvec, aka GL-ONC1, laboratory name: GLV-1h68) is an oncolytic vaccinia virus-based immunotherapy. This study is to test the hypothesis that the combination of Olvi-Vec...
Eligibility Criteria
Inclusion

- 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

- 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.
