Active clinical trials for "Ovarian Neoplasms"

Prospective, monocentric study aiming to identify factors involved in platinum based-chemotherapy resistance in patients with epithelial ovarian cancer (all stages). Patients will receive treatment (platinum based-chemotherapy) according to the standard practices. A prospective database and an associated biological collection will be performed during 5 years: For each patient: clinical, biological, epidemiological and therapeutic treatment data will be collected during the standard therapeutic care. Biological samples (blood samples, tumor biopsy specimens and ascites samples) will be collected for all patients. These samples will be collected at the same time as those taken in standard practice (no additional biopsy will be performed for the study). Study participation of each patient will be 5 years.

This study aims to evaluate the safety and efficacy of high dose inorganic selenium in preventing and relieving chemotherapy-induced peripheral neuropathy (CIPN) in platinum-sensitive recurrent ovarian, fallopian, or primary peritoneal cancer patients. This study will be conducted as a phase III randomized controlled trial in platinum-sensitive recurrent ovarian, fallopian, or primary peritoneal cancer patients who are expected to undergo paclitaxel-carboplatin chemotherapy. A total of 68 patients need to be enrolled in this study. The primary objective of this study is to evaluate the frequency of chemotherapy-induced peripheral neuropathy. The secondary objectives are the evaluation of the severity of peripheral neuropathy and the quality of life to show that selenium is effective in preventing and relieving peripheral neuropathy induced by paclitaxel. Positive results in this study will lead to further studies investigating the effect of selenium on other chemotherapies that can induce peripheral neuropathy.

The tumor organoids platform can provide the precise genetic information and phenotype, as well as the heterogeneity of the tumor, thus provide information on drug sensitivity specific to the patient.This is an exploratory research to see if organoids testing could help guide precision treatment for ovarian cancer(OC) patients.

This study is an open-label, multicentre, phase II study to evaluate the efficacy and safety of of DP303c injection in patients with HER2-expressing advanced ovarian cancer.

This prospective non-interventional study is intended to generate new data and insights into first-line (1L) treatment of newly diagnosed advanced high-grade epithelial Ovarian cancer (OC) in Germany relevant for patients, physicians and payers. It will capture the influence of 1L Poly ADP ribose polymerase inhibitor (PARPi) maintenance treatment (MTX) on medical routine in Germany, especially on: outcome of the 3-steps 1L treatment phase (including surgery, Chemotherapy (CTX) and MTX) including the potential of patients with primary advanced OC to be cured, patient's follow-up (FU) during and after MTX therapy, patient-reported outcomes (PROs), experiences and needs, physician's experience, BRCA/HRD and genomic scar testing behavior at diagnosis/during 1L therapy, patient selection for different 1L systemic treatment approaches, use and safety of drugs, treatment sequence in case of recurrence

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.

1. This is a multi-center clinical study to evaluate dual mTORC1/2 inhibitor (ATG 008) or selective inhibitor of nuclear export compound (ATG-010) in combination with chemotherapy in patients with relapsed or metastatic ovarian cancer, endometrial cancer, and cervical cancer.

Epithelial ovarian cancer is the most fatal gynecological malignancy. Despite initial therapeutic response, the majority of advanced-stage patients relapse and eventually succumb to chemoresistant disease. The majority of ovarian cancer patients with standardized treatment, including tumor cell reduction and postoperatively platinum-based combination chemotherapy, will still experience tumor recurrence and multiple recurrences within 6-18 months.With the increase in the number of recurrences, the intertherapeutic period will shorten and eventually drug resistance will emerge.The purpose of treatment for recurrent ovarian cancer is mainly to improve the quality of life of patients and prolong survival. CSPC OUYI PHARMACEUTICAL CO., LTD has successfully developed Paclitaxel (Albumin-Bound) and the bioequivalence test results show good consistency with Abraxane.To evaluate the efficacy and safety of Paclitaxel (Albumin-Bound) combination with carboplatin in Chinese patients with platinum-sensitive recurrent ovarian cancer, this clinical study is planned.

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

The purpose of this study is to answer the fundamental question 'The Optimal Timing of Surgery' in advanced ovarian cancer patients with different tumor burden, and to perform translational study.
