Filter by:Prospective single-center one-arm phase II study in patients with prostate cancer and confirmed biochemical recurrence (BCR) with PSA of ≥ 0.2 ng/ml after radical prostatectomy (RP) or PSA > nadir + 2ng/ml after radiotherapy (RT) but not radio-morphological local recurrence after primary therapy with curative intent receive systemic therapy with only 2 cycles of highly standardized (3 GBq in first cycle and 6 GBq in the second cycle) PSMA-RLT at 6-week intervals.
The purpose of this study is to determine whether the amount of time before disease progression can be prolonged in participants with metastatic castration-resistant prostate cancer (MCRPC) who receive lorigerlimab in addition to the standard of care (SOC) of docetaxel and prednisone. About 150 participants with mCRPC will be enrolled. Participants will be randomized in a 2:1 ratio to receive lorigerlimab with docetaxel and prednisone (experimental arm) or docetaxel and prednisone alone (standard-of-care arm). Lorigerlimab+docetaxel or docetaxel will be administered intravenously (IV) in clinic on Day 1 of each 3-week cycle. Prednisone will be administered orally twice daily. Lorigerlimab will be administered for up to 35 cycles. Docetaxel and prednisone will be administered up to 10 cycles until treatment discontinuation criteria are met. Participants will undergo regular testing for signs of disease progression using computed tomography (CT) scans, magnetic resonance imaging (MRI) and prostate-specific antigen (PSA) blood tests. Participants will be asked to complete questionnaires about their health and well-being. Routine examinations and blood tests will be performed and evaluated by the study doctor. Participants who have disease progression standard-of-care arm have the option of continuing on the study to receive lorigerlimab monotherapy.
This trial is a phase I open-label, single center study designed to evaluate the safety, tolerability and preliminary efficacy of the bispecific prostate specific membrane antigen (PSMA) and cluster of differentiation protein 3 (CD3) antibody CC-1 in men with biochemical recurrence (BCR) of prostate cancer (PC). The PSMA binder in CC-1 reacts with tumor cells and also binds to tumor vessels, thereby allowing for a dual mode of anti-cancer action. CC-1 was developed in a novel format, which not only prolongs serum half-life, but most importantly reduces off-target T-cell activation with accordingly reduced side effects. The study entails a part I (dose escalation part) to identify the maximally tolerated dose of CC-1, which then will be further evaluated in part II of the study (dose expansion part). After application of two low doses as safety steps in the first cycle, CC-1 will be applied twice weekly for three consecutive weeks within 4 week cycles as a short-term intravenous infusion (3 hours). The planned trial ultimately shall define the recommended phase II dose (RP2D) of CC-1 in the disease setting of BCR of PC.
In Europe, prostate cancer (PCa) is the second most frequent type of cancer in men and the third most lethal. Current clinical practices, often leading to overdiagnosis and overtreatment of indolent tumors, suffer from lack of precision calling for advanced AI models to go beyond SoA by deciphering non-intuitive, high-level medical image patterns and increase performance in discriminating indolent from aggressive disease, early predicting recurrence and detecting metastases or predicting effectiveness of therapies. To date efforts are fragmented, based on single-institution, size-limited and vendorspecific datasets while available PCa public datasets (e.g. US TCIA) are only few hundred cases making model generalizability impossible. The ProCAncer-I project brings together 20 partners, including PCa centers of reference, world leaders in AI and innovative SMEs, with recognized expertise in their respective domains, with the objective to design, develop and sustain a cloud based, secure European Image Infrastructure with tools and services for data handling. The platform hosts the largest collection of PCa multi-parametric (mp)MRI, anonymized image data worldwide (>17,000 cases), based on data donorship, in line with EU legislation (GDPR). Robust AI models are developed, based on novel ensemble learning methodologies, leading to vendor-specific and -neutral AI models for addressing 8 PCa clinical scenarios. To accelerate clinical translation of PCa AI models, we focus on improving the trust of the solutions with respect to fairness, safety, explainability and reproducibility. Metrics to monitor model performance and a causal explainability functionality are developed to further increase clinical trust and inform on possible failures and errors. A roadmap for AI models certification is defined, interacting with regulatory authorities, thus contributing to a European regulatory roadmap for validating the effectiveness of AI-based models for clinical decision making.
The aim is to investigate whether the addition of short-term androgen deprivation therapy (ADT) during 1 month or short-term ADT during 6 months together with an androgen receptor targeted therapy (ARTA) to metastasis-directed therapy (MDT) significantly prolongs poly-metastatic free survival (PMFS) and/or metastatic castration-refractory prostate cancer free survival (mCRPC-FS) in patients with oligorecurrent hormone sensitive prostate cancer.
The purpose of this Phase I/II study is to determine the safety and effectiveness of up to 5 study drugs used together for the treatment of solid tumor cancers. The drugs are hydroxychloroquine, metformin, sirolimus, dasatinib and nelfinavir and are given orally.
This observational study was designed to evaluate progression free survival after PSMA-PET/CT based salvage approach for patients affected by biochemical relapse after radical prostatectomy.
Prostate cancer is the most common cancer in males in the UK, and current estimates are that 1 in 8 will be diagnosed with prostate cancer in their lifetime. Although surgery or radiotherapy with hormone therapy offers a good chance of cure in localised disease, recurrence can occur, which may cause significant distress, and may shorten the patient's life. In patients with locally advanced disease (disease that has broken through the surrounding capsule of the prostate gland), around 30-40% of patients experience a recurrence. Cancer develops as a result of normal cells acquiring genetic mutations, and localised prostate cancer at diagnosis is commonly made up of different subclones - distinct regions within the patient's cancer with different sets of genetic mutations, each of which may behave differently and be more or less sensitive to treatments. The IMRT clinical trial (CCR 1766) recruited 486 patients who received hormone therapy and radiotherapy to the prostate and lymph nodes in patients with locally advanced prostate cancer. The FORECAST study (FORecasting the Evolution of CAncer of the proState within a Trial) is undertaking genetic sequencing of several regions of these patients' prostate cancers in order to determine which subclones are present at diagnosis, and how they evolved. FORECAST also has permission to obtain and perform sequencing on primary samples from two other large trials in localized prostate cancer. This study seeks to collect blood samples from patients who have experienced a recurrence in whom the primary biopsies have been sequenced as part of FORECAST. Additionally, blood will be collected from any patient in follow up at The Royal Marsden who received radiotherapy and hormone therapy for a localised prostate cancer and has experienced a recurrence but not yet started treatment. In these patients, the FORECAST protocol will be used to undertake genetic sequencing of their original prostate cancer biopsies. Genetic mutations from the cancer can be detected in the blood in patients who relapse, so-called 'liquid biopsies'. By comparing the genetic information between the primary and relapsed cancer, we can detect which subclones present at diagnosis are ultimately responsible for the cancer relapsing, and help us to understand the evolution of prostate cancers over time. This will assist us in predicting at the point of diagnosis which patients are more likely to relapse, so that we may consider escalating primary treatments or treating patients with high-risk subclonal mutations with targeted therapies upfront. As a result, we aim to reduce the number of patients treated for localised prostate cancer experiencing a recurrence. Additionally, although liquid biopsies are well-characterized in metastatic prostate cancer, little is known about their value in patients who have a biochemical-only relapse (patients who have a rising PSA with no evidence of cancer on scans) and this will also be explored.
The current trial will test the combination of darolutamide with SBRT, in oligometastatic recurrent hormone sensitive prostate cancer. We hypothesize that the addition of short-term darolutamide improves metastasis-free survival when added to SBRT without a detrimental impact on the QoL. Considering the large reluctance of both patients and physicians to be randomized to observation, we propose to use the historical data from previous reported randomized trials (STOMP and ORIOLE) as a comparator to explore as a secondary endpoint.
18F-PSMA-1007 is a new radiopharmaceutical for the detection of prostate cancer with potential benefits over the registered 18F-Fluciclovine (Axumin). The main potential benefit is the higher detection rate of PSMA compared to Fluciclovin in the low PSA range. It may therefore be more sensitive in detecting local disease in case of biochemical recurrens. The investigators aim to compare the detection efficacy of 18F-PSMA-1007 to 18F-Fluciclovin in prostate cancer patients with biochemical recurrence (PSA levels 0.2-5 ng/ml).
