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 Comparator Arm with platinum-doublet chemotherapy and bevacizumab in women diagnosed with platinum-resistant/refractory ovarian cancer (includes fallopian tube cancer and primary peritoneal cancer).
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Platinum-resistant Ovarian Cancer Platinum-refractory Ovarian Cancer Fallopian Tube Cancer Primary Peritoneal Cancer High-grade Serous Ovarian Cancer Endometrioid Ovarian Cancer Ovarian Clear Cell Carcinoma | Biological: olvimulogene nanivacirepvec Drug: Platinum chemotherapy: carboplatin (preferred) or cisplatin Drug: Non-platinum chemotherapy: Physician's Choice of gemcitabine, taxane (paclitaxel, docetaxel or nab-paclitaxel) or pegylated liposomal doxorubicin Drug: Bevacizumab (or biosimilar) | Phase 3 |
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 followed by further chemotherapy is particularly effective against established tumors by virus-mediated immune activation and re-sensitization of tumor cells to chemotherapy. Participant population includes histologically confirmed non-resectable platinum-resistant/refractory ovarian cancer (PRROC). Determination of progression-free survival, safety and overall survival are key objectives. Participants randomized into the Experimental Arm will receive intraperitoneal infusion of Olvi-Vec through a catheter in addition to platinum-doublet chemotherapy and bevacizumab. Treatment in the Active Comparator Arm allows the same platinum-doublet chemotherapy and bevacizumab as the Experimental Arm. Biological samples will be obtained from some Experimental Arm participants for virus-shedding testing. Assessment of response to treatment in both arms will be by RECIST 1.1 and iRECIST. Maintenance/continued treatment with non-platinum chemotherapy and bevacizumab is dependent on a participant being clinically stable until confirmed progressive disease by iRECIST or can no longer tolerate therapy.
Dr. Robert W. Holloway (AdventHealth Cancer Institute, Orlando, FL) will serve as the National Principal Investigator for this Phase 3 study in PRROC.

Primary Outcome Measures :
- Progression-free survival (PFS) by RECIST 1.1 in the Intention-to-Treat (ITT) population (all randomized participants regardless of whether they received any dose of treatment) [ Time Frame: From date of randomization up to 12 months ]To assess progression-free survival from time of randomization until first documented disease progression based on radiological assessment or death from any cause.
Secondary Outcome Measures :
- Incidence of Treatment-emergent Adverse Events in the ITT population [ Time Frame: From date of first study treatment until death or study completion; assessed up to 36 months ]Determine safety and tolerability of administering multiple doses of Olvi-Vec via intraperitoneal catheter in combination with platinum-doublet and bevacizumab (or biosimilar) as assessed by CTCAE v. 5.0 following initiation of study treatment until end of study participation.
- Duration of Response (DOR) by RECIST 1.1 in the ITT population [ Time Frame: From date of randomization up to 12 months ]Time from date of first response until the first date of progressive disease based on radiological assessment.
- PFS by RECIST 1.1 in the modified ITT (mITT) population (participants who received at least 1 dose of treatment in either Arm) [ Time Frame: From date of randomization up to 12 months ]Time from randomization to first documented disease progression based on radiological assessment or death from any cause.
- PFS by iRECIST in the ITT population [ Time Frame: From date of randomization up to 12 months ]Time from randomization to first documented disease progression with confirmatory imaging scan performed 4-8 weeks after unconfirmed disease progression or death from any cause.
- Overall Response Rate (ORR) by RECIST 1.1 in the ITT population [ Time Frame: From date of randomization up to 12 months ]Ratio of the sum of CR & PR divided by the number of ITT participants from start of treatment to confirmation of response.
- Overall Survival in the ITT population [ Time Frame: From date of randomization until death or study completion; assessed up to 36 months ]Time from randomization until date of death from any cause.
