Filter by:The purpose of the study is to determine if a radiopaque hydrogel rectal spacer, SpaceOAR Vue®, can be used in place of fiducial markers when aligning patients for radiotherapy. The investigator hypothesizes that the alignment of the patient based on the rectal spacer will be similar to the alignment of the patient with fiducial markers.
This study will use different types of medical imaging to assess how lesions from advanced prostate cancer become resistant to second-generation AR-targeted therapy, and how the different types of imaging compare in that assessment. Participants in this study have advanced prostate cancer and are either scheduled to start a second-generation androgen receptor (AR) targeted therapy (such as enzalutamide, abiraterone, or apalutamide) or are already being treated with one. Participants can expect to be in the study for at least 9 months, and up to 2 years.
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.
The study primarily aims at evaluating health-related quality of life after radiotherapy for prostate cancer, using modern hypofractionated radiotherapy schedules. Study design is a prospective observational cohort study. All patients give written informed consent and fill out online validated questionnaires before, during, and after radiotherapy (yearly) up to 5 years post-treatment.
The study investigates the influence of structured follow-up using ePROMS in the 1st year after prostatectomy on the postoperative course. It will be examined whether this intervention leads to early detection of postoperative symptoms and whether the subsequent initiation of further measures lead to an improvement of incontinence, symptom burden, quality of life and patient competence.
The aim for this study is to determine the safety and efficacy of 67Cu-SAR-BBN in participants with Gastrin Releasing Peptide Receptor (GRPR)-expressing metastatic castrate resistant prostate cancer in patients who are ineligible for therapy with 177Lu-PSMA-617.
This trial is a prospective clinical trial designed to demonstrate the safety and feasibility of whole-pelvis adaptive prostate stereotactic body radiation therapy (SBRT) with a tumor boost to the magnetic resonance (MR)-detected sites of disease. The hypothesis is that this treatment approach will be safe and feasible with <15% of patients experiencing an acute CTCAEv5 grade ≥3 genitourinary (GU) or gastrointestinal (GI) adverse event.
Tumor bone metastasis refers to the metastasis of malignant tumors to the bone through lymph, blood or direct invasion to generate daughter tumors, which is the most common bone tumor. More than 40% of patients with malignant tumors will have bone metastasis, among which breast cancer, prostate cancer is more common, once the tumor cells occur bone metastasis, it means that the disease enters the advanced stage, posing a serious threat to the life safety of patients, therefore, early diagnosis of various primary malignant tumor bone metastases, can lay the foundation for clinical implementation of effective treatment measures. The laboratory of Hank F. Kung at the University of Pennsylvania has developed a new generation of 68Ga-labeled radiopharmaceutical P15-041 ([68Ga]Ga-HBED-CC-BP) based on existing phosphonate-targeting molecular probes (Figure 1). Data from preclinical studies indicate that P15-041 shows additional advantages in rapid and easy complex formation compared to current [68Ga]Ga-BPAMD, [68Ga]Ga-NO2AP-BP, [68Ga]Ga-DOTA- (ZOL). In vivo experiments, P15-041 showed good bone resorption and rapid renal excretion in normal mice. Haiyan Hong et al. [13] prepared multiple clinical doses of P15-041 and successfully evaluated it in patients, followed by intravenous P15-041, followed by a whole body PET/CT scan. Robert K. Doot et al. conducted dosimetric experiments on P15-041, analyzed the radioactive distribution of the drug in normal organs and the dynamic change of the dose of the drug in the body over time, and the results showed that P15-041 had high uptake in the bladder wall and bone cortex, blood and other tissues cleared quickly, and there was obvious radioactive enrichment in the myocardium in the early stage of imaging, and P15-041 had the potential to become a new generation of excellent phosphonate molecular probes.
New androgen pathway targeting agents (ARTA), including Abiraterone acetate, Apalutamide and Enzalutamide, are approved and used in treatment of metastatic hormonal sensitive prostate cancer(mHSPC). However, the development of castration-resistance prostate cancer(CRPC) is only a matter of time. The use of sequential ARTAs in mCRPC showed limited benefit in retrospective series and prospective trials. Therefore this sequence should be avoided because of known cross resistance and the availability of chemotherapy and poly adenosine diphosphate-ribose polymerase(PARP) inhibitors (if a relevant mutation is present). Recently, a randomized controlled trial(RCT), the ABIDO-SOGUG, indicated that compared with docetaxel, maintaining Abiraterone added to docetaxel in chemotherapy-naive patients who have experienced cancer progression to Abiraterone treatment could not improve radiographic progression-free survival or the other endpoints.However, another RCT, the PRESIDE trial, indicated that in patients who had progressed on Enzalutamide, continued Enzalutamide treatment in combination with docetaxel led to a significant improvement of PFS compared with placebo plus docetaxel. The aims of this trial is to assess both the efficacy and safety of docetaxel in combination with Enzalutamide as first-line treatment in mCRPC patients progressed on Abiraterone.
This trial evaluates whether a network of peer genetic coaches is useful for addressing disparities in genetic testing and screening among African American men with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic). While genetic testing has become central to prostate cancer care, African American men are less likely seek testing due to lack of awareness, cultural beliefs, financial limitations, fear of discrimination, and mistrust in the healthcare system. A network of peer genetic coaches may help address barriers, beliefs, and needs of African American men in the community and provide navigation to increase engagement in genetic testing.
