Filter by:The aim of this study is to evaluate and optimize protocols for the isolation and analysis of analytes in urine (cell-free nucleic acids, extracellular vesicles and proteins). The following factors will be evaluated (1) volumetric collection with Colli-Pee®, a collection device developed by Novosanis for standardized collection of urine, and (2) stabilization methods. This is a prospective study in which urine samples will be collected from healthy volunteers, urine samples and a blood sample from pregnant women and cancer patients with solid tumors with emphasis on breast- and prostate cancer. The participants will be asked to provide a urine sample collected with the Colli-Pee® device and fill out an online questionnaire to collect usability data. Thereafter, the urine sample will be aliquoted to be used in different pilot studies for the protocol optimization. For the pilot study where the effect of volume will be assessed, participants will be requested to collect multiple samples with different Colli-Pee® variants and fill out questionnaires accordingly.
The goal of the proposed project is to test the implementation strategy, in terms of feasibility and utility, of an online Tai Chi intervention as a prehabilitation model to prepare prostate cancer patients and their caregivers for radical prostatectomy (RP). The investigators' hypothesis is that, by using an online teaching module, the proposed prehabilitation model is feasible on the prostate cancer care pathway in a simple, efficient, and minimally disruptive manner. In addition, participating in the Tai Chi intervention will improve patient anxiety leading up to the RP and improve physical function as well as post-operative side-effects associated with RP. Our primary objective is to test the feasibility of the implementation strategy from multi-stakeholder perspectives. The investigators will use mixed-methods to assess the barriers and facilitators related to implementing the online Tai Chi intervention from multi-stakeholder perspectives guided by the Consolidated Framework for Implementation Research. Our secondary objective is to examine the effect of the Tai Chi intervention on patient outcomes at peri-RP and post-RP. The investigators will quantitatively test the effect of the intervention to reduce peri- and post-RP anxiety and improve peri- and post-RP physical function and general disease specific patient-reported outcomes. An exploratory objective is to explore the effect of the Tai Chi intervention on surgical outcomes. The study team will quantitatively describe the difference in post-RP surgical outcomes between the intervention and control groups.
Study of NGM438 as Monotherapy and in Combination with Pembrolizumab in Advanced or Metastatic Solid Tumors
Doctors leading this study plan to collect new information about the lowest effective dose of abiraterone acetate in study participants with prostate cancer who are taking abiraterone in combination with prednisone for the first time. The duration of this study will be about 3 months (12 weeks). How long you stay on abiraterone, and at what dose after completion of the 12 weeks of study drug administration, will be up to you and your treating physician.
Approximately 50-60% of men undergoing salvage brachytherapy post cancer recurrence to the prostate have the disease controlled at 5 years. This study aims to integrate a local treatment to the prostate (brachytherapy) with a treatment involving 177Lutetium (Lu)- Prostate-Specific Membrane Antigen (PSMA) therapy. Differently than brachytherapy, 177-Lutetium-PSMA is thought to have its effect not only to the cancer cells within the prostate, but also to cancer cells located elsewhere in the body. Thus, the idea here is that by adding 177Lutetium (Lu)- PSMA early in the course of treatment we may be able to inactivate potential metastatic cells outside the prostate, while the prostate cancer within this organ still treated by the combination of brachytherapy and 177-Lutetium-PSMA.
This phase II trial studies the effect of rectal spacer hydrogel before radiation therapy in reducing radiation dose to the rectum in patients with prostate cancer. Rectal spacer hydrogen is a soft gel material used to create a space between the rectum and prostate during radiation treatment. The rectal spacer gel is made up of 90% water and 10% polyethylene glycol and is injected as a liquid through a needle inserted between the rectum and prostate. It stays in place for about 3 months and is naturally absorbed into the body and removed through urine in about 6 months. By pushing the prostate further from the rectum with the hydrogel, it may help spare the rectum from receiving radiation during standard of care stereotactic body radiation therapy and brachytherapy treatment.
This is an observational study in which patient data from the past on men with prostate cancer are studied. Cancer is a condition in which the body cannot control the growth of cells and tumors may form. If tumors form in the prostate, male sex hormones (androgens) can sometimes help the cancer spread and grow. Cancer that spreads to other parts of the body is called metastasis. Androgens are mainly made in the testicles. There are treatments available for men with prostate cancer to lower the levels of these hormones in the body. These treatments are called androgen deprivation therapy (ADT). Some men with prostate cancer respond to ADT, but in some cases, prostate cancer may overcome the therapy and worsen despite low androgens levels. Second generation androgen receptor inhibitors (SGARIs) including darolutamide, apalutamide, and enzalutamide are available for the treatment of prostate cancer in addition to ADT. SGARIs work by blocking androgens from attaching to proteins in cancer cells in the prostate. Clinical studies have shown that men with prostate cancer benefit from these treatments. But besides benefits, unfavorable reactions related to these treatments also influence which treatment is chosen, if the treatment is taken as intended or if it is even stopped. Unfavorable reactions observed for darolutamide, apalutamide, and enzalutamide differ from each other. In clinical trials, severe unfavorable reactions occurred less often for darolutamide. But information on how unfavorable reactions of each treatment influence their intake in actual or "real-world" prostate cancer treatment is missing. The main aim of this observational study is to learn to what extent SGARI treatments are taken as prescribed and how often their intake is completely stopped. To find this out, researchers will collect available treatment data of adult men with prostate cancer from the United States who started SGARI treatments between August 2019 and March 2021. The data will be drawn from the IQVIA database. For each man, data from up to 1 year prior SGARI treatment until at least 3 months after treatment start (up to the 30 June 2021) will be collected. The researchers will look at the percentage of men who: - completely stopped to take their treatment or - took the treatment as prescribed. The results for each treatment (darolutamide, apalutamide, and enzalutamide) will then be compared to find possible differences. There will be no required visits with a study doctor or required tests in this study since only patient data from the past are studied.
This is an observational study where prostate cancer related PROMs (EPIC-26) is collected using two different methods (by paper questionnaires and electronically) and patient experience and preference is asked.
This phase II study will investigate the activity and safety of radionuclide 177Lu-PSMA therapy versus 177Lu-PSMA in combination with Ipilimumab and Nivolumab in patients with metastatic castrate resistant prostate cancer (mCRPC).
This prospective phase II study assesses the accuracy of second generation prostate specific membrane antigen (PSMA) positron emission tomography (PET; utilizing 18F-PSMA-1007)) and multiparametric magnetic resonance imaging (MRI) for locoregional staging of clinically significant prostate cancer in men undergoing radical prostatectomy and bilateral pelvic lymph node dissection. The design will be a multicenter validating-paired cohort study using radical prostatectomy and pelvic lymph node dissection as the gold standard comparator. Each patient will undergo both 18F-PSMA-1007 PET and 3T MRI allowing comparison of each imaging modality within each subject. Furthermore, PET and MRI will be compared to standard-of-care imaging techniques (CT abdomen/pelvis and 99mTc-MDP Bone scan).
