Filter by:In this study, up to 21 patients with metastatic prostate cancer will receive UV1 (a therapeutic synthetic peptide vaccine) at different dose levels. The safety and tolerability of UV1 as well as immunological response will be assessed. The purpose of this study is to select a biological dose of peptides for further clinical trials. Main treatment period is completed and reported. Follow-up ongoing.
A study to investigate which of two different tablet formulations of ODM-201 is best suited for use in the further development of the compound in the treatment of metastatic chemotherapy-naive castration-resistant prostate cancer. Patients successfully completing the bioavailability study will be able to receive further treatment with the current capsule formulation of ODM-201 until progression of their disease with the safety and tolerability of ODM-201 being assessed throughout.
A prostate cancer diagnosis starts a list of events that often leads to fast-moving treatment, thought by many to result in vast over-treatment of this disease. So, discovery of different diagnostic methods that allow clinicians to identify slow-growing from potentially fast-growing disease prior to or at the time of prostate biopsy could result in early and suitable treatment for men at greatest risk, while greatly decreasing the number of biopsies, surgical procedures, hormonal and chemotherapeutic treatments, cost, and patient worry, for those with more slow-growing disease.
Success of cancer immunotherapy is limited by the ability of solid tumors to evade local and systemic antitumoral immune responses. Several mechanisms of tumor immune evasion have been identified, including low intratumor expression of antigens and elevated expression of inhibitory co-regulatory molecules. An effective immunotherapy is one which would induce necrotic cell death and accompanying proinflammatory cytokine induction. Stereotactic Body Radiotherapy (SBRT) or Intensity Modulated Radiotherapy (IMRT) or brachytherapy, which is capable of delivering high, conformal radiation doses (>8 Gy) of tumor ablative radiation may be an effective means of conditioning a tumor bed to a state favorable to the initiation of robust antitumoral immune responses.
When evaluating prostate cancer patients for recurrent disease, computed tomography (CT), and magnetic resonance imaging (MRI) are both highly sensitive methods for detecting lymph nodes, but are not specific as to whether the lymph nodes are malignant or benign. While positron emission tomography (PET) utilizing radioactive glucose (FDG) has revolutionized staging, restaging, and monitoring response to therapy in many prevalent cancers such as breast, colorectal, esophageal, head and neck, lung, lymphoma, and melanoma, findings with prostate cancer have proven less sensitive because prostate cancer has a lower avidity for glucose. A newer PET isotope, utilizing acetate that is incorporated into the cell membrane of rapidly proliferating cells, has shown greater sensitivity than FDG in detecting prostate cancer. This study will assess the clinical effectiveness of utilizing [11C]Acetate PET scans in identifying recurrent prostate cancer.
The purpose of this study is to see if a new diagnostic research agent named 89Zr-DFO-MSTP2109A can show prostate cancer tumors on a PET scan; as well as see how long 89Zr-DFO-MSTP2109A lasts in the blood when given in small amounts. DFO-MSTP2109A is an antibody that works against STEAP1 - found on the surface of prostate cancer cells. Attached to the DFO-MSTP2109A is a radioactive material called 89ZR, which allows it to be imaged by a PET scanner. The results of this study may help researchers know whether 89Zr-DFO-MSTP2109A can be used as a diagnostic agent for finding prostate cancer that have STEAP1 on its surface with a PET scanner. The reason why identifying STEAP1 on prostate cancer cells is that new therapies are being developed to target STEAP1 prostate cancer cells.
Nodal involvement among patients with prostate cancer is known to be a poor prognostic factor. Traditionally, the presence or absence of nodal disease in patients with prostate cancer is ascertained with the use of anatomical imaging methods such as computed tomography (CT) and magnetic resonance imaging (MRI). However, the sensitivities of CT and MRI for the detection of pelvic nodal disease is rather low, with reports placing the value to lie between 50-80%. Positron emission tomography (PET) with the use of carbon-11 or fluorine-18 tagged choline (Choline-PET) is an approach which is known to deliver a high sensitivity for the imaging of prostate cancer disease burden in the primary, nodal and the metastatic areas. The investigators in this prospective trial intend to utilize Choline-PET among all newly diagnosed patients of prostate cancer who are presumed to be non-N1 (absence of nodal disease on conventional imaging) and non-M1 (absence of metastatic disease on conventional imaging).
The investigators' goal is to develop a non-selective and non-invasive procedure to identify aggressive tumors and simultaneously identify their exact location in Prostate cancer patients undergoing radical prostatectomy by combining multiparametric MRI and machine learning techniques. The combination of multi-parametric MRI and machine learning (validated using histopathology) can lead to increased sensitivity and specificity of cancer foci in the prostate, and help in isolating aggressive from indolent tumors. This increased sensitivity and specificity may eventually lead to: a) a reduction in the number of patients that undergo unnecessary treatment, and b) enhance current treatment options by enabling the use of focused therapies. The investigators will recruit 15 patients with prostate cancer that are currently scheduled to undergo radical prostatectomy into the study. All patients will obtain an advanced MRI study prior to the radical prostatectomy. MRI scans will include a) high-resolution volumetric images using T1 and T2-weighted imaging, b) vascular images using dynamic contrast enhanced (DCE) imaging, c) biophysical microstructure images using diffusion-weighted imaging, and d) biochemical images using MR spectroscopic imaging. Following radical prostatectomy, a pathologist will grade the prostatectomy specimens based on standard of care (Gleason grading system). Correlations will be generated between the parameters obtained from scans and from clinical assessments.
Quality of life data following SBRT for prostate cancer has been obtained in only a small numbers of patients. A prospective study using validated quality of life questionnaires is needed to determine outcomes after treatment with SBRT. Our study will be the first essential step in developing a better evidence base on the comparative risks and benefits of SBRT treatment with regards to quality of life assessment and outcomes.
This pilot clinical trial studies magnetic resonance imaging (MRI)-transrectal ultrasound (TRUS) fusion image-guided prostate biopsy following radical prostatectomy in patients with prostate cancer. Diagnostic procedures, such as MRI-TRUS fusion image-guided prostate biopsy may help find and diagnose prostate cancer
