Filter by:This is single center, open-label phase 1 dose escalation trial that uses modified 3+3 design to identify a recommended phase 2 dose (RP2D) of CAR.B7-H3 T cell product. An expansion cohort will enroll additional subjects at the RP2D for a total enrollment of up to 21 subjects on the protocol.
Ovarian cancer is the most common cause of death in gynecological cancer. Approximately 75% of epithelial ovarian cancers are detected at an advanced stage. Metastasis and spread are mostly through transperitoneal planting and neighborhood by shedding from the ovarian surface. Metastasis mostly occurs in the peritoneum, omentum, and intestines. The rectosigmoid colon is the main part of the intestine affected by metastasis due to its neighborhood. Treatment in ovarian cancer consists of a combination of cytoreduction surgery and platinum-based chemotherapy. Surgery is the basis of the treatment, and the main goal is to achieve no residual visible tumor (complete cytoreduction: R0). The residual tumor is one of the main factors affecting survival and reflects the possibilities of the surgical center and the team. Multiple surgical procedures (total hysterectomy, bilateral salpingo-oophorectomy, total omentectomy, peritonectomy, retroperitoneal lymphadenectomies such as pelvic and paraaortic, bowel resections, splenectomy, distal pancreatectomy, various resections related to the bladder, liver, stomach, and diaphragm) may be required to achieve complete or optimal cytoreduction. In the involvement of the rectosigmoid colon, primarily the serosa, then the muscular layer and finally the mucosa are infiltrated due to the nature of the spread, and therefore most of the involvement is observed in the seromuscular layer. In seromuscular infiltration, resection of the rectosigmoid colon or shaving of tumoral implants without resection can be performed. There are advantages and disadvantages of each method in terms of morbidity. Although there are retrospective studies evaluating recurrence and survival between both methods, as far as investigators know, no randomized prospective studies have been conducted comparing these two methods. The investigators designed this study to compare these two methods successfully applied in our clinic in a prospective randomized study.
Liquid biopsy is challenging for the diagnosis of epithelial ovarian cancer (EOC). In this study, we performed the methylation testing of host DNA, namely, OPCML, FODX3 and CDH13, in the peripheral serum to discover the diagnostic and supervision roles of DNA methylation in EOC patients. The study compromises two stages. In the training set, DNA methylation testing is performed in the ovarian tissues from EOC and paired benign ovarian tumor patients. The cut-off values of methylation are produced in this stage. On the meantime, serum DNA methylation testing is also performed to reveal its accordance and accuracy compared with the results of ovarian tissues. In the validation set, serum DNA methylation testing is performed in unselected ovarian tumor patients with definite cut-off values to validate its accuracy based on known histology of ovarian tumors. In training and validation sets, serum DNA methylation is also performed after major surgeries for EOC as to illustrate the changes of methylation testing, therefore, reflection the supervision role of DNA methylation.
A homologous recombination deficiency (HRD) scoring model based on loss of heterozygosity (LOH) is little explored in epithelial ovarian cancer (EOC) patients. This study would recruit 200 Chinese EOC patients with known BRCA1/2 mutation status and resistance to platinum-based chemotherapy. A LOH-HRD model is to be constructed based on the genetic testing in these patients. The mutated genes, HRD score model and their relationship with the prognosis, would provide a full description of for the Chinese EOC patients, and a potential explanation of platinum-resistance in such population.
This is a multi-center, prospective, open-label, phase II trial. Patients with suspected advanced ovarian cancer planned to undergo diagnostic laparoscopy for histologic confirmation and evaluation of disease spread will be registered into the trial after providing a 1st written informed consent.
This is an open-label, single-arm, phase I/II, single-center study with dose finding and dose expansion parts. This study hypothesizes that the combination of platinum-based chemotherapy, Oregovomab and Nivolumab will improve intracellular CA 125 antigen processing and elicit a stronger systemic CA 125-specific T cell response and that it will be in a manner that is synergistic, safe and clinical efficacious in patients with relapsed platinum sensitive epithelial ovarian carcinoma (EOC).
This is a longitudinal observational phase II, single center, single arm study on the reliability of high grade serous ovarian carcinoma organoids obtained from primary debulking surgery (PDS)+adjuvant chemotherapy and neoadjuvant chemotherapy + interval debulking surgery (NACT+IDS) cases as model for the patients' response to treatments. Since organoids represent a model system comparable to patient-derived xenografts, the investigators tested the null hypothesis that the possibility of correctly identifying the drug-sensitivity could improve from 80%, as assessed by xenografts to at least 95%. The first step was planned to include 7 patients; if 5 or more patients do not respond, the trial will be terminated. If the trial goes on to the second stage, a total of 43 patients will be studied. Considering a patient dropout of approximately 10%, the study was planned to enroll at least 48 patients.
This is a Phase 1b open-label, multicenter study, evaluating the safety, tolerability, preliminary clinical activity, pharmacokinetics (PK), and pharmacodynamics of ZN-c3 in combination with other drugs.
Epithelial ovarian cancer (EOC) is a tumor entity featured by frequent involvement of peritoneum, also called peritoneal carcinomatosis. It is a type of metastasis accompanied by significant cancer-associated fibroblasts (CAFs) accumulation. Fibroblast activation protein (FAP) is a protein that is overexpressed on CAFs and can be non-invasively monitored by a novel radiotracer called 68Ga-FAPI-04 positron emission tomography/computed tomography (PET/CT). In this study, we will explore the value of 68Ga-FAPI-04 PET/CT in patients with epithelial ovarian cancer who are scheduled for surgical intervention. The findings of 68Ga-FAPI-04 PET/CT will also be compared with that of 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose (18F-FDG) PET/CT, which is one of the most commonly used modalities in evaluating EOC, and histological findings.
A phase III prospective study with the primary objective to investigate the benefit of Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in ovarian cancer patients with mutations in homologous recombination repair (HRR) genes. The target population for this study is patients with recurrent ovarian, peritoneal or fallopian tube cancers undergoing Cytoreductive Surgery (CRS). Patients will be divided into two groups according to HRR genes mutation, each group will be further divided into two sub-groups with different intervention. Patients in Group A are HRR mutated type, sub-group 1 will undergo CRS plus HIPEC and then go on to receive standard platinum-based combination doublet intravenous chemotherapy, sub-group 2 will undergo CRS and then go on to intravenous chemotherapy. Patients in Group B are HRR wild type, sub-group 3 will undergo CRS plus HIPEC and then go on to receive standard platinum-based combination doublet intravenous chemotherapy, sub-group 4 will undergo CRS and then go on to intravenous chemotherapy. All patients will receive maintenance therapy with Niraparib after primary treatment. Prognostic information will be collected for investigation of survival benefits of patients.
