Testing Whether the Combination of Two Immunotherapy Drugs Have Activity in Recurrent or Persistent Clear Cell Ovarian Cancer
Description

This phase II trial studies how well pembrolizumab and epacadostat work in treating patients with ovarian clear cell carcinoma that has come back (recurrent), remains despite treatment (persistent), or is growing, spreading, or getting worse (progressive). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Epacadostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and epacadostat may work better compared to usual treatment (surgery, radiation, or cytotoxic chemotherapy) in treating patients with ovarian clear cell carcinoma.

Folate Receptor Alpha Dendritic Cells (FRαDCs) or Placebo for the Treatment of Patients With Stage III or IV Ovarian, Fallopian Tube, or Primary Peritoneal Cancer, FAROUT Trial
Description

This phase II trial compares the effect of folate receptor alpha dendritic cells (FRαDCs) to placebo in treating patients with stage III or IV ovarian, fallopian tube or primary peritoneal cancer. FRαDCs, a dendritic cell vaccine, is made from a person's white blood cells. The white blood cells are treated in the laboratory to make dendritic cells (a type of immune cell) mixed with folate receptor alpha (FRalpha), a protein found in high levels on ovarian tumor cells. FRαDCs work by boosting the immune system to recognize and destroy the tumor cells by targeting the FRalpha protein on the tumor cell. Placebo is an inactive substance that looks the same as, and is given the same way as, the active drug or treatment being tested. The effects of the active drug are compared to the effects of the placebo. Giving FRαDCs may work better in preventing or delaying recurrence compared to placebo in patients with stage III or IV ovarian, fallopian tube, or primary peritoneal cancer.

M1774 and ZEN-3694 combined together has demonstrated to be better than either drug alone in killing ovarian tumor cells.

SUSPENDED
Vaccine Therapy Plus Pembrolizumab in Treating Advanced Ovarian, Fallopian Tube, or Primary Peritoneal Cavity Cancer
Description

This phase I/II trial tests the safety, side effects, best dose, and effectiveness of multi-epitope folate receptor alpha-loaded dendritic cell vaccine (FRalphaDC) with pembrolizumab in treating patients with ovarian, fallopian tube, or primary peritoneal cancer (collectively known as ovarian cancer) that that has come back (after a period of improvement) (recurrent). Ovarian cancer is the most lethal gynecologic malignancy in the United States. While the majority of patients achieve a remission from ovarian cancer with the combination of aggressive cytoreductive surgery and cytotoxic chemotherapy, over 80% of patients develop recurrence within 3 years of completion of treatment. Additional treatments are needed for recurrence, but the standard treatment modalities are non-curative in nature due to the development of drug resistance. As such, there is a great unmet need for treatment strategies that utilize new mechanisms to which drug resistance does not develop. FRalphaDC is a dendritic cell vaccine that is made from the white blood cells collected from a procedure call apheresis. The white blood cells are treated to make dendritic cells, which will then be incubated with peptides, which are pieces of a protein known as "folate receptor alpha" (FRalpha), a protein that is found in high levels on ovarian cancer cells. Dendritic cell vaccines work by boosting the immune system (a system in the body that protect against infection) to recognize and destroy the tumor cells by targeting the FRalpha protein. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving FRalphaDC vaccine with pembrolizumab may be a safe and effective treatment for recurrent ovarian cancer.

Efficacy & Safety of Olvi-Vec and Platinum-doublet + Bevacizumab Compared to Physician's Choice of Chemotherapy and Bevacizumab in Platinum-Resistant/Refractory Ovarian Cancer (PRROC) (OnPrime, GOG-3076)
Description

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.

RECRUITING
Pembrolizumab Combined With Bevacizumab With or Without Agonist Anti-CD40 CDX-1140 for the Treatment of Patients With Recurrent Ovarian Cancer
Description

This phase II trial tests whether pembrolizumab combined with bevacizumab with or without agonist anti-CD40 CDX-1140 works to shrink tumors in patients with ovarian cancer that has come back (recurrent). Anti-CD40 CDX-1140 works by stimulating certain immune cells within the tumor and, when combined with other immunotherapy treatments, may increase antitumor antibody production. Immunotherapy with monoclonal antibodies, such as pembrolizumab and bevacizumab, may help the body's immune system, and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab and bevacizumab with anti-CD40 CDX-1140 may decrease symptoms, prolonged survival, and improve quality of life in patients with ovarian cancer.

Minimally Invasive Surgery After Neoadjuvant Chemotherapy for the Treatment of Stage IIIC-IV Ovarian, Primary Peritoneal, or Fallopian Tube Cancer, LANCE Trial
Description

This phase III trial compares minimally invasive surgery (MIS) to laparotomy in treating patients with stage IIIC-IV ovarian, primary peritoneal, or fallopian tube cancer who are receiving chemotherapy before and after surgery (neoadjuvant chemotherapy). MIS is a surgical procedure that uses small incision(s) and is intended to produce minimal blood loss and pain for the patient. Laparotomy is a surgical procedure which allows the doctors to remove some or all of the tumor and check if the disease has spread to other organs in the body. MIS may work the same or better than standard laparotomy after chemotherapy in prolonging the return of the disease and/or improving quality of life after surgery.
