Filter by:This phase III trial tests two questions by two separate comparisons of therapies. The first question is whether enhanced therapy (apalutamide in combination with abiraterone + prednisone) added to standard of care (prostate radiation therapy and short term androgen deprivation) is more effective compared to standard of care alone in patients with prostate cancer who experience biochemical recurrence (a rise in the blood level of prostate specific antigen [PSA] after surgical removal of the prostate cancer). A second question tests treatment in patients with biochemical recurrence who show prostate cancer spreading outside the pelvis (metastasis) by positron emission tomography (PET) imaging. In these patients, the benefit of adding metastasis-directed radiation to enhanced therapy (apalutamide in combination with abiraterone + prednisone) is tested. Diagnostic procedures, such as PET, may help doctors look for cancer that has spread to the pelvis. Androgens are hormones that may cause the growth of prostate cancer cells. Apalutamide may help fight prostate cancer by blocking the use of androgens by the tumor cells. Metastasis-directed targeted radiation therapy uses high energy rays to kill tumor cells and shrink tumors that have spread. This trial may help doctors determine if using PET results to deliver more tailored treatment (i.e., adding apalutamide, with or without targeted radiation therapy, to standard of care treatment) works better than standard of care treatment alone in patients with biochemical recurrence of prostate cancer.
Evaluation of the interest of PET-PSMA imaging potentiated by androgen blockade in patients with biological relapse or persistent biological disease of a localized prostatic adenocarcinoma after initial treatment
This randomized double-blinded Phase II clinical trial will evaluate the bioavailability, safety, effectiveness and validate the mechanism by which a standardized formulation of whole Green Tea Catechin, (Sunphenon® 90D) containing 405 mgs vs. Placebo, administered for 24 months in a cohort of men with low to intermediate grade prostate managed on active surveillance
The purpose of this study is to evaluate safety and short-term oncological efficacy of the NanoKnife Irreversible Electroporation System for localised prostate cancer. Irreversible electroporation (IRE) is the method of focal treatment for prostate cancer, which is already proven by FDA as method of the surgical ablation of soft tissue. It has not received clearance for the therapy or treatment of any specific disease or condition.
This phase II trial studies how well prostate specific membrane antigen (PSMA) or fluciclovine positron emission tomography (PET)/computed tomography (CT) site-directed therapy works for treating patients with prostate cancer. PSMA or fluciclovine PET/CT may detect prostate cancer early and may help to show whether patients benefit from site directed treatment to PET detected abnormalities.
An active surveillance protocol for patients diagnosed low-risk prostate cancer will be held. We plan to use PSA (prostate-specific antigen) testing, DRE (digital rectal examination), TRUS (transrectal ultrasound), MRI (magnetic resonance imaging) and follow-up biopsies to monitor patients and detect cancer progression in time.
This phase II trial studies how well gallium-68 PSMA-11 PET/CT works for the diagnosis of prostate cancer with rising PSA following prostatectomy or radiation therapy (biochemically recurrent). Gallium-68 PSMA-11 is a radioactive tracer. PET/CT scans reveal information about both the structure and function of cells and tissues in the body during a single imaging session using a radioactive compound. This trial is being done to see if gallium-68 PSMA-11 PET/CT scan works better in diagnosing prostate cancer compared to standard C-11 choline PET/CT scans.
This phase III trial studies whether adding apalutamide to the usual treatment improves outcome in patients with lymph node positive prostate cancer after surgery. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgens, or male sex hormones, can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may help stop or reduce the growth of prostate cancer cell growth by blocking the attachment of androgen to its receptors on cancer cells, a mechanism similar to stopping the entrance of a key into its lock. Adding apalutamide to the usual hormone therapy and radiation therapy after surgery may stabilize prostate cancer and prevent it from spreading and extend time without disease spreading compared to the usual approach.
The study is a non-randomized, prospective trial of men scheduled for radical prostatectomy for treatment of prostate cancer as standard of care and will undergo a series of pre-operative multi-modality imaging studies. Pre-operative imaging will be correlated with actual pathology results and statistical modeling performed to determine the most informative imaging biomarkers in predicting cancer location and aggressiveness (Gleason Score).
Men diagnosed with significant cancer confined to the prostate currently undergo radical therapy directed to the whole prostate (radiotherapy or prostatectomy). These provide good cancer control but can cause significant side effects. Focal Therapy involves targeting the cancer alone, whilst leaving healthy prostate gland alone. Case series have shown similar cancer control over 5 years with a much better side effect profile. However, there have been no randomised control trials (RCTs) comparing the success in cancer control and the quality of life in patients that undergo radical therapy vs those that undergo focal therapy. Further, there is a need to assess the use of additional therapies that may improve the cancer control outcomes following focal therapy. By having a trials platform with two RCTs (CHRONOS-A and CHRONOS-B) that reflect best patient and physician preferences/ equipoise, the investigators aim to answer these questions. To improve acceptability, recruitment and compliance, the investigators have an embedded study aimed at reviewing clinician and patient perspectives and trial acceptability. CHRONOS-A will compare radical therapy to focal therapy, whilst CHRONOS-B will compare focal therapy alone to focal therapy with various therapies targeting the testosterone pathway that can shrink the cancer before it is treated. The investigators think this might improve outcomes further for men that definitely want focal therapy.
