Filter by:Single-centre single-armed, non-randomized interventional phase II-study of hypofractionated image-guided radiotherapy "IGRT" with weekly magnetic resonance imagings "MRI" for personalized adaptation of the treatment plan depending on individual MR-anatomy of prostate/organ at risks "OAR" during course of IGRT.
Thirty-five men with newly diagnosed, metastatic prostate cancer are scanned with 18F-PSMA 1007 PET/CT at baseline, 3 weeks after the initiation of GnRH-antagonist, at one year and at the time of castration resistant prostate cancer (CRPC). The aim of the study is to classify metastatic lesions into those with PSMA-flare and those without and determine their potential to progress during the follow-up until CRPC.
The Principal Investigator's (PI) working hypothesis is that the PI can utilize the high predictive value of 18F-DCFPyl PSMA to identify clinically significant tumors in patients who will undergo brachytherapy, as well as areas which are uninvolved or contain only clinically insignificant disease. In the PI's clinical trial, the uninvolved regions (as defined by combined PET-MR-biopsy data) will not be targeted and receive only fall-off dose, which we have shown to be associated with reductions in toxicity.
This study involves patients who are scheduled for standard care brachytherapy of focal tumours within the prostate, which is normally performed under standard 2-dimensional (2D) ultrasound guidance. The purpose of this study is the acquire power Doppler ultrasound while using a simple oscillator in physical contact with the end of a brachytherapy needle. The vibrations along the needle should be visible in the power Doppler ultrasound, helping to visualize the needle position within the anatomy.
This study is an open-label, Phase 1, multicenter study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamic (PD) profiles of a novel fragment crystallizable (Fc)-engineered immunoglobulin G1 anti-cytotoxic T-lymphocyte antigen 4 (anti-CTLA-4) human monoclonal antibody (botensilimab) monotherapy and in combination with an anti-programmed cell death protein-1 (PD-1) antibody (balstilimab), and to assess the maximum tolerated dose (MTD) in participants with advanced solid tumors. This study will also determine the recommended phase 2 dose (RP2D) of botensilimab monotherapy and in combination with balstilimab.
PSMA-radioguided surgery
One in 8 men will be diagnosed with prostate cancer during their lifetime. The majority of men diagnosed with prostate cancer have early stage disease, which can be managed in a variety of ways, ranging from monitoring to international treatment. However is it not always clear which treatment option is best. All men with newly diagnosed localised prostate cancer are assigned a disease risk category (low/intermediate/high risk). This is based on clinical findings and prostate biopsy results, but these factors are limited in their ability to distinguish between aggressive and indolent prostate cancers. The current risk grouping can make it difficult to plan appropriate treatment tailored and personalised to the individual patient. There is evidence reporting overtreatment of localised prostate cancer in the UK. However, many patients with aggressive disease are wrongly assigned a low risk categorisation and are recommended surveillance when better suited to more interventional treatment. Myriad Genetics have developed a test, called Prolaris which measures how fast cells in a prostate cancer are dividing to assess its aggressiveness. The Prolaris test is performed on routine prostate biopsy tissue, so patients are not subjected to any additional invasive investigations. In this study, led by Leeds Teaching Hospitals NHS Trust, the aim is find out if the Prolaris® test score helps patients with newly diagnosed prostate cancer and their clinical team make better informed treatment choices that are tailored to the individual patient. The aim to achieve a Prolaris risk score for 100 patients and determine the impact it has on treatment decision making. The research team will look at how the test fits into routine clinical practice, investigate the clinician and patient views and understanding on the test report and assess the quality of life of patients in the different risk and treatment groups.
The current study aims to examine the hypothesis that combining the focal effects of HIFU with the systemic effects of androgen deprivation therapy might eradicate the prostatic cancer cells by targeting the 'visible' index focus (by HIFU) and the tumour surrounding microenvironment which may contain 'invisible' foci and aberrant PCa related signalling (by androgen deprivation therapy) to enhance oncological outcomes of HIFU hemi-ablation in men with localized PCa, and consequently reducing treatment failures.
Multi-modality therapy that includes a brachytherapy implant improves outcomes in locally advanced prostate cancer when compared to other radiation-based treatments, but is also associated with more adverse side effects. The goal of the OPTiMAL trial is to reduce these side effects by using advanced imaging and biopsy techniques to locate cancer and deliver precision radiation therapy, while not compromising the unprecedented high cure rates obtained for the brachytherapy arm of the Androgen Suppression Combined with Elective Nodal and Dose Escalated Radiation Therapy (ASCENDE-RT) randomized control trial. Additionally, some applied research in genetics, pathology and medical imaging is included. Novel medical imaging methods, namely, multi-parametric magnetic resonance imaging (MRI), multi-parametric trans-rectal ultrasound (TRUS), prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) are used for re-staging of prostate cancer. This is followed by trans-perineal biopsy to locate cancerous areas of the prostate with greater precision compared to conventional biopsy. Results from imaging are compared to those from biopsy to develop image-based cancer detection methods.
The investigators are conducting this study with men that have prostate cancer and are getting standard of care treatment with the drugs abiraterone acetate and prednisone. The study will follow men with prostate cancer from initiation of participation in the study and for up to 10 years. The reason for the study is that researchers think that there may be a connection between the race and ethnicity of men with prostate cancer and how well the standard treatments work for the participants.
