Platinum-Resistant Primary Peritoneal Carcinoma

This trial will treat patients with platinum resistant ovarian, fallopian tube or primary peritoneal cancer as defined by a progression free interval within six months of completion of most recent platinum-based treatment with a combination of vismodegib and atezolizumab. Despite recent improvements in treatment of ovarian cancer with the introduction of PARP inhibitors, response rates to therapy in the platinum resistant setting remain dismal with response rates of only 10-20% reported for single agent cytotoxic therapies. Given the poor prognosis and limited treatment options for these patients, this population is considered appropriate for trials of novel therapeutic candidates.

This phase II trial studies the side effects of ONC201 and paclitaxel and how well they work in treating patients with platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent), or that does not respond to treatment (refractory). ONC201 is the first in its class of drugs that antagonize some specific cell receptors on cancer cells, leading to their destruction. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ONC201 and paclitaxel may work better in treating patients with platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer compared to paclitaxel alone.

Study CP-MGD019-03 is an open-label study of lorigerlimab in participants with platinum-resistant ovarian cancer (PROC) or clear cell gynecologic cancer (CCGC). Approximately 80 participants will be enrolled. The study will assess the efficacy and safety of lorigerlimab in participants with PROC or CCGC. Participants will receive lorigerlimab by intravenous (IV) infusion on Day 1 of every 21-day treatment cycle. Treatment cycles will continue until progression of cancer, unacceptable side effects, withdrawal of consent by the participant, or the study ends. Participants will be monitored closely for side effects by physical exam and routine laboratory tests every cycle. Tumor status will be checked approximately every 9 weeks for the first year, then every 12 weeks for the duration of treatment. Participants will have a safety followup performed within 30 days after treatment discontinuation. Participants who discontinue study treatment for reasons other than progression of cancer, will continue CA-125 and tumor assessments every 12 weeks. Participants who discontinue study treatment for progression of cancer will enter the 6-month survival follow up portion of the study.

This phase I trial tests the safety, side effects, best dose of MUC1-activated T cells in treating patients with ovarian cancer that has come back after a period of improvement (relapsed) or that remains despite treatment (resistant). T cells are infection fighting blood cells that can kill tumor cells. The T cells given in this study will come from the patient and are made in a laboratory to recognize MUC1, a protein on the surface of tumor cells that plays a key role in tumor cell growth. These MUC1-activated T cells may help the body's immune system identify and kill MUC1 expressing ovarian tumor cells.

This phase II trial tests whether pegylated SN-38 conjugate PLX038 (PLX038) works to shrink tumors in patients with ovarian, primary peritoneal, and fallopian tube cancers that has spread from where it first started (primary site) to other places in the body (metastatic). PLX038 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This is a phase-3, open-label, multicenter, two-arm treatment study to evaluate the efficacy and safety of weekly Paclitaxel Lipid Suspension compared with weekly conventional paclitaxel in participants with platinum-resistant/refractory recurrent high-grade serous epithelial ovarian cancer. Paclitaxel Lipid Suspension or conventional paclitaxel will be administered intravenously at a dose level of 80 mg/m2 on Day 1, Day 8 and Day 15 of each 28 days cycle. The primary objective is to establish the non-inferiority of Paclitaxel Lipid Suspension in comparison with conventional paclitaxel for Injection in participants with platinum-resistant/refractory recurrent advanced high-grade serous epithelial ovarian cancer including fallopian tube and/or primary peritoneal cancer. Participants in both arms will be dosed with the drug until disease progression as assessed by investigator and/or unacceptable toxicity.
