Filter by:The purpose of this study is to assess the safety, tolerability and efficacy of the study drug AO-252 and identify the best dose for use in future studies.
The objective of this study is to explore the integration of in vivo and ex vivo of MRI with histology and molecular assessments to advance non-invasive characterization of tumor heterogeneity in high-grade serous ovarian cance
The purpose of this research is to test the effectiveness and safety of the study drugs (VS-6766 and defactinib), and see what effects (good and bad) these drugs have on the patients with endometrioid cancer, mucinous ovarian cancer, high-grade serous ovarian cancer, or cervical cancer.
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.
High grade serous ovarian cancer represents the gynecological malignancy with the highest incidence of mortality. Decision-making tools are currently limited to the use of standard imaging modalities and analysis of serum biomarkers, such as CA 125, which often have low specificity and sensitivity. Recently, a growing research interest has been aimed at so-called circulating microRNAs (miRNAs). Indeed, it has been observed that miRNAs are abundantly present in all biological fluids and play the key role of messengers in intercellular communication. Cancer cells have a rapid turnover which results in a continuous release of nucleic acids and vesicles derived from the tumor itself, such as the tumor cells themselves that separate from the tumor mass to enter the bloodstream. Given their important role as modulators of gene expression, in order to preserve their integrity, miRNAs are encapsulated in specific vesicles, in order to prevent their degradation by the enzymes present in biological fluids. In this context, the chance of monitoring the expression levels of specific miRNAs represents a very interesting option both for an early diagnosis and for monitoring the clinical response to pharmacological treatment. Currently, there are no non-invasive approaches to monitor the clinical outcome in real time, while the identification of circulating biomarkers would allow prompt intervention, possibly modifying the pharmacological management in case of progression.
This study is a prospective observational clinical trial. Patients who were diagnosed and treated for the first time were enrolled and their surgical pathology was confirmed to be high-grade serous ovarian cancer. At the same time, these patients will receive first-line maintenance treatment with PARP inhibitors after traditional chemotherapy. During the trial period, patients' plasma will be collected before surgery, after chemotherapy, during targeted maintenance therapy, and during disease progression, and ctDNA-specific genomes will be detected, and clinical data will be collected over the same period. It is expected that specific ctDNA can be used to predict the efficacy of PARP inhibitors in patients with ovarian cancer, and to detect the recurrence of the disease early.
Around 15-25% of ovarian cancer (OC) patients carry germ-line mutation in BRCA1 or BRCA2 genes. Recent evidences showed that OC women with germline BRCA1/2 mutations (gBRCAmut) have an improved survival and higher platinum-sensitivity compared to BRCA1/2 naive (BRCAwt). Interestingly, disease appearance in BRCAmut women is more diffuse than in BRCAwt cases, with significantly higher peritoneal tumour load. Nonetheless, BRCAmut women additionally show a higher benefit of platinum-based neoadjuvant chemotherapy (NACT) plus interval debulking surgery compared with BRCAwt women in terms of clinical and pathological responses, suggesting that BRCA mutational status might be used as a molecular tool to personalize treatment in high-grade serous ovarian cancer (HGSOC) patients. OLAPARIB in BRCA mutation carriers Olaparib is a potent oral poly (ADP-ribose) polymerase (PARP) inhibitor that causes synthetic lethality in BRCA1/2-deficient tumour cells. In patients with platinum-sensitive relapsed serous ovarian cancer, olaparib maintenance treatment significantly improved the duration of progression-free survival compared with placebo (hazard ratio [HR] 0.35 [95% CI (confidence interval) 0.25-0.49]; p<0.0001), with the greatest clinical benefit in patients with BRCA mutations (HR 0.18 [95% CI 0.10-0.31]; p<0.0001). Preclinical data suggest that olaparib might also potentiate the efficacy of DNA-damaging chemotherapies, including platinum-containing drugs such as carboplatin. In a recent phase Ib/II study, olaparib plus weekly carboplatin and paclitaxel in relapsed ovarian cancer patients was shown to be safe, well tolerated and effective, especially in germline BRCA mutated (gBRCAmut) patients. Possibly, the addition of a PARP inhibitor (olaparib) to NACT in HGSOC patient with germline or somatic BRCA1/2 mutation is able to increase the pathological complete response rate to conventional chemotherapy. Combination of intermittent olaparib with weekly carboplatin and paclitaxel might achieve a higher pathological response rate, with an acceptable toxicity profile.
