Filter by:This study is an open-label, multicenter, umbrella study aimed to evaluate the combined, biomarker-driven, targeted treatment efficiency of Pamiparib, Bevacizumab, Tislelizumab, and Nab-paclitaxel in patients with platinum-resistant recurrent ovarian cancer (PROC).
Homologous recombination deficiency (HRD) is an important molecular biomarker for Poly (ADP-ribose) polymerase inhibitors (PARPi) which is a significant progress in the treatment of ovarian cancer. However, the proportion of HRD positive in real world and relationship of HRD status with PARPi in Chinese ovarian cancer patients remains unknown.
The purpose of this study is to determine the treatment efficacy of CYH33 monotherapy in patients with recurrent or persistent ovarian, fallopian tube or primary peritoneal clear cell carcinoma harboring PIK3CA hotspot mutation, who received prior systemic anti-tumor treatment.
This is a Phase 3, randomized, open-label, 2-stage, multicenter study of navicixizumab with or without paclitaxel compared with paclitaxel monotherapy in patients with platinum-resistant advanced epithelial ovarian cancer and specific biomarkers, as measured by the proprietary and validated Xerna™ TME Panel biomarker assay. Eligible patients must have received at least 2 prior regimens but not more than 5 prior regimens, including treatment with a monoclonal antibody angiogenesis inhibitor (e.g., bevacizumab), must be considered platinum-resistant, and must be considered appropriate to receive single-agent paclitaxel chemotherapy as a next line of therapy. All patients must be willing and able to provide a formalin-fixed paraffin embedded (FFPE) archive or core tumor sample collected during screening for classification as B+ or B- biomarker status based on RNA expression data from the Xerna™ TME Panel biomarker assay. The co-primary efficacy endpoints are ORR by RECIST v1.1 and PFS (as assessed by blinded independent radiological review [BIRR]) analyzed at different timepoints. Analysis of the ORR primary efficacy endpoints will occur at the end of Stage 1 and at the end of Stage 2; the PFS primary efficacy endpoint will be analyzed at the end of Stage 2.
PICCOLO (IMGN853-0419) is a Phase 2 multicenter, open label study designed to evaluate the safety and efficacy of Mirvetuximab Soravtansine in participants with platinum-sensitive ovarian, primary peritoneal or fallopian tube cancers with high folate receptor-alpha (FRα) expression.
This is a Phase 2, multicenter, two-stage, open-label, parallel-group study designed to evaluate the efficacy and safety of vudalimab (XmAb20717) in patients with selected advanced gynecologic and genitourinary malignancies.
In 2020, epithelial ovarian cancer (EOC) accounts for 313,959 new cases and 207,252 deaths worldwide. The standardized 5-year net survival of a woman with EOC is 44% for cases diagnosed between 2005-2010. This is because 2 out of 3 cancers are found at an advanced stage with invasion beyond the ovaries to the entire peritoneum or distant metastasis. Treatment of EOC is currently based on platinum-based chemotherapy combined with paclitaxel and maximal cytoreduction surgery. Newer combination therapies may be introduced such as bevacizumab and oral poly ADP-ribose polymerase (PARP) inhibitors. Despite the combination of different therapeutic modes, the 5-year survival has not progressed much since the 1980s. The development of new and more effective therapies is essential but requires a better understanding of cancer heterogeneity and the identification of new therapeutic targets. Cancer heterogeneity results from genetic and transcriptional variations between tumors but also between cells of the same tumor. This heterogeneity has an impact on the development of the tumor and its resistance to treatment. One of the methods to study this heterogeneity is single cell RNA sequencing (scRNAseq) which allows to analyze individually and simultaneously the gene expression (transcriptomics) of thousands of cells. Studies on EOC using this technique have already been performed but they were based on small numbers with very different tumor types and stages. The objective of this protocol is to characterize by scRNA-seq the architecture and microenvironment of primary and secondary tumors of 50 patients with EOC at the single cell level and to correlate the data with the clinical characteristics of the patients, especially during recurrence and/or chemoresistance, in order to identify the molecular parameters allowing tumor cells to acquire survival, invasion, metastasis and chemoresistance capacity as well as to carry out the inventory of cell populations within the different sites of EOC. We will also analyze the interaction between tumor cells and the microenvironment, by studying on the one hand the involvement of immune cells in the antitumor response and on the other hand how tumor cells modulate the microenvironment to make it permissive to the development of the EOC. We will compare the data obtained for each patient with healthy tissue (from the same patient) in order to determine the common and specific tumor molecular signatures in EOC, the latter point allowing us to evaluate the intra and inter-patient variability. Similarly, the comparison of the transcriptomic profile of the same tumor subtype in several patients will allow us to determine if certain transcriptional perturbations are ubiquitous. The identification of these common pathways would allow the discovery of potential therapeutic targets. Furthermore, the molecular processes leading to chemoresistance are still unknown. We will investigate whether known chemoresistance markers are present in tumor cells from primary sites and whether their presence correlates with the response to treatment in patients. We will also study the molecular mechanisms of resistance to treatment in our patients which will ultimately allow the development of new therapies. We will also try to find new prognostic markers which is made possible by the clinical follow-up of the patients. The existence of this heterogeneity will be confirmed by complementary genetic analyses of the genome and exome (search for mutations, variation in gene copy number or chromosome copy number, epigenetic effects) by different molecular biology techniques (qPCR, NGS sequencing) and the markers that will be identified can be confirmed by histochemical analysis.
The purpose of this study is to determine if exercise preconditioning can mitigate the off target effects of chemotherapy treatment on measures of cardiovascular function, peripheral neuropathy, and quality of life.
The objective of the study is to investigate the metabolism of cells in the ascites tumour microenvironment of ovarian cancer patients. This observational study involves intravenous infusion of [U-13C]glucose into patients during standard paracentesis.
The main aim of this study is to check for side effects from treatment with niraparib. The study sponsor will not be involved in how the participants are treated but will provide instructions on how the clinics will record what happens during the study. During the study, participants with ovarian cancer will take capsules of niraparib (Zedula) once a day according to their clinic's standard practice. The study doctors will check for side effects from niraparib for 1 year after treatment starts.
