Filter by:The aim of the study is to determine if PET-CT imaging (using contrast recommended in clinical guidelines) is superior to combined bone scan and MRI/CT of the abdomen & pelvis in detecting the increased incidence of metastasis (nodal/distant outside the pelvis) in men with prostatic carcinoma with germline BRCA mutations.
PARP inhibitors are most effective in homologous recombinant (HR) deficient tumors. There are clear indications that besides BRCA1 or BRCA2 mutated EOC, there is an additional group of EOC having deficiencies in HR (i.e. BRCAness) that might benefit from treatment with PARP inhibitors. Assessment of HR in high grade EOC might therefore serve as a better predictive biomarker and allow the identification of a larger group of patients that could benefit most from platinum based chemotherapy and maintenance treatment with a PARP inhibitor. We recently developed a robust ex vivo functional assay (RAD51 assay;) to test HR in viable tumor tissue. In the proposed study, we will evaluate whether the RAD51 assay predicts sensitivity to therapy with olaparib, in patients with recurrent EOC. With the RAD51 assay we aim to identify a larger number of patients who will benefit from treatment with the PARP inhibitor olaparib than patients with a germline or somatic BRCA mutation only. Furthermore, we aim to identify molecular markers (including genomic markers) that are associated with the outcome of the RAD51 assay. Finally, we will explore whether these molecular markers can be measured in liquid biopsies by analysing ctDNA.
The purpose of this study is to assess an intervention that incorporates engagement strategies with a medical team navigator, an educational video and accessible genetic testing services to maximize the genetic testing and education of at-risk relatives. In this study, first degree relatives who agree to participate will either receive this intervention or standard of care. The investigators do not know if the facilitated interventional method will be more effective than the standard of care method. This research is being done because identification of patients with inherited gynecologic/breast cancer syndromes is critical to enable delivery of tailored cancer treatment and cancer prevention to both the patients and their at-risk relatives. Cascade genetic testing, defined as extending genetic testing to the family members of affected patients, results in a more precise risk assessment and initiation of appropriate cancer screening and prevention strategies. Therefore, this trial will compare the efficacy of a multicomponent facilitated intervention for first degree relatives vs. standard of care in terms of the overall proportion of first degree relatives who complete genetic testing by 6 months (primary outcome).
PARP inhibitors have changed the treatment paradigm of ovarian cancer. Most patients using PARP(poly-ADP ribose polymerase) inhibitors will suffer different grades of adverse events(AEs), followed by dose reduction. It has not been reported whether the dose-reduced olaparib as maintenance treatment have an impact on efficacy. Both PAOLA-1 and AVANOVA 2 studies showed that combined PARP inhibitors and antiangiogenic drugs have synergistic anti-tumor effect. Anlotinib is a novel multi-target tyrosine kinase inhibitor that can inhibit VEGFR(vascular endothelial growth factor receptor), FGFR(fibroblast growth factor receptor), PDGFR(platelet-derived growth factor receptor) α/β, c-Kit, and Ret. And anlotinib has been approved as orphan drug designations for treatment of ovarian cancer by FDA in 2015. Previous studies showed that anlotinib had manageable toxicity and promising antitumor effect. Our study is expected to investigate the efficacy and safety of anlotinib combined with dose-reduced olaparib as maintenance treatment in platinum-sensitive recurrent ovarian cancer patients.
Niraparib is an oral, potent and highly selective PARP1/2 inhibitor. It can be used as a single drug in HRD positive ovarian cancer patients for multi-line therapy. Bevacizumab is a recombinant humanized monoclonal antibody that inhibits tumor angiogenesis and is also recommended for the treatment of recurrent ovarian cancer. Clinical studies showed that niraparib combined with bevacizumab could significantly prolong progression free survival of platinum sensitive recurrent ovarian cancer. We intend to conduct a single-arm, prospective, open-label, phase II study to observe the efficacy and safety of niraparib combined with bevacizumab in the treatment of FIGO III/IV platinum refractory/resistant ovarian cancer, fallopian tube cancer and primary peritoneal cancer. The results are expected to provide more effective and precise treatment for platinum resistant recurrent/refractory ovarian cancer patients.
To evaluate immune function in BRCA1/2 mutation carriers without cancer, specifically to determine whether immune function in healthy individuals with germline loss of function BRCA1/2 mutations, impacts overall immune health and fitness.
Hereditary cancer programs face challenges with respect to effective communication of genetic test results within families and uptake of genetic testing by relatives. This study aims to determine if a "disclosure toolkit" provided to the index participant (carrier of cancer risk gene mutation) contributes to sharing genetic test results with relatives, if there are preferred disclosure methods, and whether toolkit use contributes towards at-risk relatives pursuing genetic testing.
The purpose of this study is to validate the interest of broadband spectroscopy analysis (femto/attosecond by infrared laser) on liquid biopsies in breast cancer screening.
The homologous recombination deficiency (HRD) status in Chinese population with epithelial ovarian cancer (EOC) is little known. This study would recruit 1300 Chinese EOC patients. A multi-panel testing of 36 genes would be given for these patients in their peripheral blood and tumor tissues. These 36 genes include: BRCA1, BRCA2, ABRAXAS1(FAM175A）, ATM, ATR, BAP1, BARD1, BRIP1, C11ORF30（EMSY）, CDK12, CHEK1, CHEK2, FANCA, FANCC, FANCD2, FANCI, FANCL, MRE11A, NBN, PALB2, PPP2R2A, PTEN, RAD50, RAD51B, RAD51C, RAD51D, RAD54B, RAD54, MLH1, MSH2, MSH6, PMS2, EPCAM, STK11, TP53, CDH1. The study would select 150 patients with pathogenic or likely pathogenic mutations in BRCA1/2 and 150 patients without these mutations to further explore the HRD status. The HRD model is based on the loss of heterozygosity (LOH), telomere allele imbalance (TAI) and large-scale state transitions (LST). The mutated genes, HRD score model and their relationship with the prognosis, would provide a full description of for the Chinese EOC patients.
The clinical trial is a phase 1, single-arm trial that will evaluate the safety of the investigational treatment on metastatic cancer in patients who have a deleterious or suspected deleterious BRCA1, BRCA2, or PALB2 genetic alteration. The investigational treatment will involve 2 cycles of a combination of intravenous melphalan, BCNU, low-dose I.V. ethanol, vitamin B12b, and vitamin C in association with autologous hematopoietic stem cell infusion. A dose-escalation schedule will be employed for vitamin C.
