Ovarian Epithelial Carcinoma clinical trials at UCSD

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 Physician's Choice of chemotherapy and bevacizumab in women diagnosed with platinum-resistant/refractory ovarian cancer (includes fallopian tube cancer and primary peritoneal cancer). This Phase III trial builds on the efficacy and safety data reported in the previous Phase II VIRO-15 trial with promising objective response rate and progression-free survival observed in heavily pre-treated patients with platinum-resistant/refractory ovarian cancer. The phase II results also showed that the intra-peritoneal route of delivery was efficient in generating tumor cell killing and immune activation, and led to clinical reversal of platinum-resistance or refractoriness in this difficult-to-treat patient population.

Patients will be registered prior to, during or at the completion of neoadjuvant chemotherapy (Paclitaxel 175 mg/m2 IV over 3 hours and Carboplatin AUC 6 IV on Day 1 every 21 days for 3-4 cycles). Registered patients who progress during neoadjuvant chemotherapy will not be eligible for iCRS and will be removed from the study. Following completion of neoadjuvant chemotherapy, interval cytoreductive surgery (iCRS) will be performed in the usual fashion in both arms. Patients will be randomized at the time of iCRS (iCRS must achieve no gross residual disease or no disease >1.0 cm in largest diameter) to receive HIPEC or no HIPEC. Patients randomized to HIPEC (Arm A) will receive a single dose of cisplatin (100mg/m2 IP over 90 minutes at 42 C) as HIPEC. After postoperative recovery patients will receive standard post-operative platinum-based combination chemotherapy. Patients randomized to surgery only (Arm B) will receive postoperative standard chemotherapy after recovery from surgery. Both groups will receive an additional 2-3 cycles of platinum-based combination chemotherapy per institutional standard (Paclitaxel 175 mg/m2 IV over 3 hours and Carboplatin AUC 6 IV on Day 1 every 21 days for 2-3 cycles) for a maximum total of 6 cycles of chemotherapy (neoadjuvant plus post-operative cycles) followed by niraparib individualized dosing until progression or 36 months (if no evidence of disease).

This phase 3 study will be conducted in different countries all over the world. The purpose of this study is to compare how well Rina-S works against platinum-resistant ovarian cancer compared to chemotherapy drugs that are already approved and used for platinum-resistant ovarian cancer. Treatment in this study could be Rina-S or it could be 1 of 4 indicated chemotherapy agents that are considered standard medical care. There is an equal (50:50) chance of getting Rina-S or an approved chemotherapy agent as treatment in this study. No one will know what treatment they are assigned to until the first dose. All participants will receive active drug; no one will be given placebo.
