Filter by:Metformin is used widely in the treatment of type 2 diabetes. It has off-label indications for use in the prevention of diabetes and in hyperinsulinar obesity. In medical practices, the implementation of metformin for these off-label indications is variable, often at the level of the provider. Multiple retrospective investigations have also shown a clinical benefit in men with prostate cancer who are incidentally treated with metformin. This pragmatic study will test the feasibility of enrolling patients who have glucose intolerance (as defined by HbA1c of 5.7-6.4%) and/or who have increased BMI (BMI greater than or equal to 25 kg/m2) to a randomized pragmatic study of metformin plus lifestyle modification information versus lifestyle modification information only. For purposes of the scope of this project and the study's feasibility, this will be implemented in a group of prostate cancer patients, who may have additional benefits from metformin.
The aim of this study is to evaluate the feasibility to treat localized prostate cancer diagnosed with MRI and targeted/systematic biopsies, with IRE in comparison with conventional radical treatments with the primary objective to locally control the tumour with a minimum of side effects.
This is a study to evaluate the safety and clinical activity of the combination of olaparib and high-dose IV ascorbate, as second or later line of therapy, in castration resistant prostate cancer patients with no known DNA repair gene mutations (DDRm). In brief, the primary endpoint is PSA50 response , defined by a 50% reduction in PSA from baseline . The secondary endpoints are assessing the PSA doubling time, radiographic and PSA PFS, safety and tolerability as defined by the incidence of grade 3 to 5 toxicities, and measuring overall survival.
Phase 2 open-label, single-arm clinical trial evaluating the efficacy and safety of neoadjuvant olaparib + LHRH agonist administered for 6 months prior to radical prostatectomy (RP) in men with unfavorable intermediate-risk or high-risk localized prostate cancer. All patients must have confirmed germline or somatic BRCA1/2 gene mutation. Germline and somatic mutation testing will be performed as part of commercially available CLIA assays and will be validated on a uniform platform centrally all patients retrospectively. Eligible patients will receive treatment with olaparib + LHRH agonist. Following 6 months of therapy, patients will undergo RP with mandatory lymph node dissection. The lymph node dissection template will be at the discretion of the treating urologist. RP specimens will undergo pathology blinded independent central review. Following RP, patients will be followed for testosterone recovery and PSA progression.
This protocol describes development and user testing of an educational shared decision making intervention to help men with prostate cancer who are on active surveillance make decisions with their health care providers about if and when to de-escalate surveillance testing. The project is important because for many patients their cancer does not progress to the point of needed curative treatment or their health status changes such that they are no longer good candidates for treatment. For these men, de-escalating ongoing surveillance (e.g., fewer biopsies or imaging studies) is a reasonable option.
This feasibility study is investigating the application of magnetic resonance imaging (MRI) and transperineal ultrasound (TPUS) to visualise potential sites of relapse and surrounding normal tissue in patient having post-operative prostate cancer radiotherapy. Structure visualisation on MRI and TPUS will be compared to current standard computer tomography (CT) and cone-beam computer tomography (CBCT) imaging.
This study will be designed to define the efficacy and safety of ablative therapies in the management of localized prostate cancer and comprehensively evaluate quality of life outcomes and oncologic control following treatment.
Until now, clinicians have been challenged to improve the treatment of biochemically recurrent (BCR) prostate cancer in which prostatic specific antigen (PSA) rises without radiological or clinical progression years after localized treatment (radical prostatectomy or radiation therapy) with or without hormonal treatment. Approximately 50-90% of men with high-risk prostate cancer will experience a BCR. Artesunate has demonstrated anti-tumor activity in both in vivo and in vitro cell lines. It is hypothesized that Artemisia annua (Aa) coffee has the potential to decrease rising PSA among patients with biochemical recurrence of prostate cancer.
The purpose of this study is to evaluate the imaging and gene expression biomarkers in prostate cancer. Participants have high-risk prostate cancer and have indicated they will undergo external beam radiation therapy, brachytherapy, and androgen deprivation therapy (EBRT+BTX+ADT). Participants can expect to be in this study for up to 5 years.
A variety of in vivo experimental models have been established for the studies of human cancer using both cancer cell lines and patient-derived xenografts (PDXs). In order to meet the aspiration of precision medicine, the in vivo murine models have been widely adopted. However, common constraints such as high cost, long duration of experiments, and low engraftment efficiency remained to be resolved. The chick embryo chorioallantoic membrane (CAM) is an alternative model to overcome some of these limitations. The chick CAM is shown to be a robust model for both the inoculation of cell lines and grafting of patient tumors for drug therapy evaluations and target genes/pathways analysis. The start-up INOVOTION has developed a unique, highly sensitive and reproducible CAM assay to graft human cancer cells/tumors in the chicken egg environment. INOVOTION's technology was validated for over 55 human tumor cell lines, including carcinomas, gliomas and melanomas, as well as over 30 reference drugs currently on the market. At INOVOTION, the graft of human cancer cells on the chicken CAM is currently conducted manually. To scale-up, the process was recently automated. The automation performance was assessed on cancer cells lines. The objective of this study is to demonstrate that the automation of the INOVOTION process enables tumors' proliferation using patient samples (from tumor samples or circulating tumor cells) as grafting material.
