Filter by:This study evaluates the diagnostic performance and safety of [18F]PSMA-1007 PET/CT imaging in patients with suspected recurrence of prostate cancer after previous definitive treatment.
PYTHON is designed to establish the efficacy and safety of 18F-DCFPyL in comparison with that of 18F-fluorocholine, in patients with first biochemical recurrence (BCR) after initial definitive therapy (prostatectomy, external beam radiotherapy or brachytherapy) for histopathologically confirmed prostate adenocarcinoma per original diagnosis. PET/CT scans will be each interpreted by three independent masked experts who are not otherwise involved in the trial.
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.
This is a prospective, Phase 3 non-randomized, open label, multi-centre clinical trial to assess the safety and efficacy of [18F]PSMA-1007 Injection (investigational product or IP) in evaluating men with suspected persistent or recurrent disease (i.e., with biochemical failure), but with negative or equivocal conventional re-staging imaging (bone scan [BS] and computed tomography [CT] of abdomen and pelvis).
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.
This study provides expanded access to radiotracer Gallium 68 (68Ga)-prostate-specific membrane antigen (PSMA)-HBED-CC (68Ga-PSMA-11) with Positron Emission Tomography (PET) imaging for participants with intermediate and high risk prostate cancer before prostatectomy or for suspected biochemical recurrence of their prostate cancer. Compared to conventional imaging, 68Ga PSMA-HBED-CC might improve the ability to localize the sites of recurrent or metastatic disease, which helps with surgical and other treatment planning.
The purpose of this phase I/Ib study is to determine the safety profile of Epidiolex (CBD oil) in biochemically recurrent prostate cancer patients. The study consists of a dose escalation part and dose expansion part. The dose expansion part of the study will use the maximum tolerated dose (MTD) determined in the dose escalation part to assess the activity, safety and tolerability of the investigational product in patients with biochemically recurrent prostate cancer after localized therapy with either surgery or radiation.
Molecular nuclear imaging in prostate cancer has made significant progress in the last few years. The introduction of tracers that target the prostate-specific membrane antigen (PSMA) has profoundly influenced imaging diagnostics in prostate cancer. In case of relapse after curative treatment (especially after radical prostatectomy), PSMA positron emission tomography (PET) has the ability to detect lesions already at very low prostate-specific antigen (PSA) levels. The improved detection of relapses increases the interest of individualized targeted therapies in patients with prostate cancer recurrence. Thus, this development led to the acceptance of PSMA PET for diagnostics in prostate cancer patients with biochemical relapses in national and international guidelines.
The current study is a prospective, interventional, randomized, treatment-controlled study, evaluating the use of Meditation with a Mantra (MM) to decrease anxiety levels and improve Quality of Life (QOL) in prostate cancer patients receiving radiation treatment. The study will be conducted across 6 radiation treatment sessions in men with newly diagnosed prostate cancer, Stage 1 to 3A, and men with recurrent prostate cancer. Patients will receive six radiation sessions with usual care with or without the addition of MM. MM Group patients will be given a log at the beginning of the study to record how long they are meditating and if they found meditation beneficial. The General Anxiety Disorder-7 scale (GAD-7) is a validated tool and will be used to assess anxiety in all participants. The Functional Assessment of Cancer Therapy-Prostate, Version 4 (FACT-P) is a validated measure of QOL in prostate cancer patients and will be used to assess QOL in all participants. A one month follow up phone call will determine if the patients are continuing to use the MM and if they found the practice of MM useful not only in their radiation treatment sessions but in their everyday lives.
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).
