Filter by:Epithelial ovarian cancer (OC) is the most lethal gynecologic cancer: nearly 22,000 women are diagnosed with OC in the US annually and 63% are expected to die from their disease. The 5-year overall survival rate is unacceptably low at 20-30%, with > 50% of patients experiencing recurrence of their disease. Recurrent, platinum-resistant OC is characterized by a low response to chemotherapy (<10-15%) and poor prognosis, with overall survival estimated to be <12 months. Thus, there is an urgent need to identify novel therapies to improve outcomes for patients with recurrent, platinum resistant OC. The primary focus in this trial is targeting tumor associated immunosuppressive T-regs with E7777 combined with PD-1 inhibitor, pembrolizumab. This trial will enroll patients with solid tumors in the dose escalation portion and specified cohorts in the dose expansion portion. In the Phase I portion, 18-30 patients will be enrolled. In the dose expansion portion, approximately 40 patients (20 in each cohort) will be enrolled. Given the relatively poor prognosis and limited treatment options for these patients, this population is considered appropriate for trials of novel therapeutic candidates.
This is a Phase 1/2 study to evaluate the safety, clinical activity, pharmacokinetics (PK), and pharmacodynamics (PD) of ZN-c3 in combination with niraparib in subjects with platinum-resistant ovarian cancer.
Epithelial ovarian cancer (EOC) diagnosed in the initial stage (stage I-II) require complete staging surgery to histologically assess the possible existence of peritoneal or lymph node disease. Systematic pelvic and paraaortic lymphadenectomy in stage I-II EOC is essential since confirming the presence of lymph node metastases means re-staging the disease as stage III. This change of stage has important prognostic and therapeutic implications. However, the lymph node involvement rate is around 10-30% (average of 15%). Systematic pelvic and para-aortic lymphadenectomy carries a risk of intraoperative complications, as well as longer operative time, postoperative complications and longer hospital stay. Moreover, by now there is no evidence suggesting a possible therapeutic value. The sentinel lymph node (SLN) detects the first level of lymph node drainage. The absence of metastases in the SLN predicts the absence of tumor infiltration of the rest of lymph nodes of the same anatomical region and allows to safely avoid lymphadenectomy and its associated morbidity. In addition, the exhaustive evaluation of the SLN by ultrastaging and immunohistochemical study allows to increase the detection of microscopic disease. Sentinel lymph node (SLN) biopsy, implemented in clinical practice in other gynecological tumors (breast, vulva, cervix or endometrium), has been studied very little in the initial ovarian epithelial cancer. Unlike other gynecological tumors, there are multiple anatomical and technical aspects that largely explain this lack of information. The double ovarian vascularization that accompanies lymphatic drainage explains this higher complexity. Therefore, at the present time, the detection of SLN in the initial EOC remains an experimental area without applicability in clinical practice. There are multiple doubts and issues to be resolved regarding the different tracers, the site and time injection and the actual accuracy of the SLN versus the lymphadenectomy.
Randomized, open label, phase II multicenter study to assess the efficacy niraparib versus niraparib +bevacizumab maintenance in patients with newly diagnosed stage IIIA/B/C high-grade epithelial ovarian cancer with no residual disease after frontline surgery and treatment by adjuvant platinum-basedchemotherapy +/-bevacizumab.
This is a single-center, observational clinical study that plans to recruit 64 ovarian cancer patients within one year. The purpose of this study is to evaluate the consistency and accuracy of the organoid model derived from patients with ovarian cancer and the patient's clinical medication, so as to predict the clinical efficacy of anti-cancer drugs
Cancers of the pancreas, bile ducts, stomach and ovaries are dismal diseases with most patients being diagnosed in advanced stages leading to a bad prognosis. These cancers can be difficult to diagnose and sometimes impossible to differentiate from underlying benign conditions. Establishing the correct diagnosis of primary cancer lesions and possible spread to other organs in time is pivotal for choosing the right therapy. Routinely applied staging procedures are however not always reliable. The main aim in this study is to evaluate the diagnostic accuracy of PET/CT with a novel radiotracer, FAPI, in the primary diagnosis of cancers in the pancreas, stomach and bile ducts as well as in patients with primary and recurrent epithelial ovarian cancer (EOC).
This study was designed to explore the safety and efficacy of Bevacizumab combined with Fluzoparib, Bevacizumab combined with chemotherapy or Fluzoparib monotherapy in patients with platinum-resistant recurrent ovarian cancer.
Endometriosis (EMS) is a chronic, invaliding, inflammatory gynaecological condition affecting 10-15% of women in reproductive age. EMS is characterized by lesions of endometrial-like tissue outside the uterus involving pelvic peritoneum and ovaries. In addition, distant foci are sometimes observed. Unfortunately, the aetiology of the EMS is little known. Although non-malignant, EMS shares similar features with cancer, such as development of local and distant foci, resistance to apoptosis and invasion of other tissues with subsequent damage to the target organs. Moreover, patients with EMS (particularly ovarian EMS) showed high risk (about 3 to 10 times) of developing epithelial ovarian cancer (EOC). Epidemiologic, morphological and molecular studies reported endometrioma as the precursor of EOC, including clear cell (CCC) endometrioid carcinoma which are both called "EMS-related ovarian carcinoma (EROC)". To date, it remains unclear why benign EMS causes malignant transformation. This multi-step process, unlike high-grade serous carcinomas, offers the possibility to identify the carcinoma precursors enabling an early diagnosis and in the early stages of the disease. EOC is the most lethal female gynecological cancer with 25% 5-year overall survival (OS), due to the lack of effective screening tools, and rapidly spreads over the entire peritoneal surface (carcinosis) thus involving all abdominal organs. Diagnosis and clinical staging of EOC is currently performed by qualitative image evaluation although the sensitivity/specificity is suboptimal. To date, diagnostic, staging, and prognostic factors are strongly correlated with subjective assessment training and clinician experience. Genomic analysis based on Next Generation Sequencing (NGS) has revealed the presence of cancer-associated gene mutations in EMS. Moreover, the chronic inflammatory process of EMS involves many factors, such as hormones, cytokines, glycoproteins, and angiogenic factors, which are expected to become early EMS biomarkers. A promising new branch of cancer research is the use of artificial intelligence (AI) to recognize new image patterns and texture and/or detecting novel biomarkers to improve the early identification of EROC patients. AI has never been used for EROC and we want to investigate whether these methods/techniques can support and even improve current diagnostics and risk assessment. AI will be used to construct a new 3D risk assessment model based on images and volume of interest
This trial is a multicenter, single-arm, phase II study evaluating the efficacy of pembrolizumab and bevacizumab in combination with platinum-based chemotherapy (PBC) followed by pembrolizumab, bevacizumab and olaparib as a maintenance therapy in patients with platinum-sensitive recurrent ovarian cancer.This study is planned to enroll eligible 35 patients from multiple study sites in Japan.
The study's purpose is to understand the effects of a new treatment (suba-itraconazole and tamoxifen) in epithelial ovarian cancer. Who is it for? Patients may be eligible to join this study with ovarian cancer resistant to platinum-based chemotherapy agents Study Details: Participants will receive different doses of tamoxifen and suba-itraconazole to determine the optimal combination dose. Participants will be seen by the investigators once a week for the first 3 weeks and then once every 4 weeks. Participant will be reviewed by a clinician and undergo regular blood tests, cardiac monitoring and imaging assessments.
