NCT04583072
Introduction: Prostate cancer (PCa) is the most commonly detected cancer in men and is the second leading cause of cancer death. Differences in race and ethnicity have been shown to have differences in PCa incidence, detection, and outcomes. Current prostate cancer screening involves prostatic specific antigen (PSA) which is a nonspecific protein marker (aka kallikrein) that can often leads to unnecessary biopsies (up to 74% benign biopsies) and clinical overdiagnosis (with up to 22% clinically insignificant cancer). Recently more sophisticated tests have been developed for PCa screening in the United States such as the Prostate Health Index (PHI) and the 4k (kallikrein) score, as well as clinical models that use information from the patient clinical history. However, these tests utilize limited serum protein assays and none of the established screening protocols utilize genetic variables to help account for the likely inherited risks as seen in different ethnicities. A recent Swedish, prospective, population-based study, published in the Lancet Oncology, developed a unique multivariable biopsy outcome prediction model within a Nordic population of nearly 60,000 men. This model, the Stockholm3, which incorporated plasma protein markers, germline DNA SNPs as well as clinical variables, was shown to be capable of reducing the number of biopsies by 44% compared to PSA while maintaining adequate sensitivity for detection of PCa. It is unknown whether an approach developed in Sweden that incorporates protein markers, genetics, clinical variables, and genetic ancestry would be beneficial in a racially diverse cohort. Hypothesis: The investigators hypothesize that, a prospectively studied multiethnic cohort of men with the Stockholm3 test will identify unique and common risk factors that improve prostate cancer detection. Aim: To assess the performance of the Stockholm3 test as compared to PSA and to identify unique features associated with PCa in Black/African American (n=500), Asian (n=500), White/Caucasian Hispanic (n=500), and White/Caucasian Non-Hispanic (n=500) men. Methods: The investigators propose a prospectively identified cohort with participating institutions which have screened positive to undergo a prostate biopsy to have a retrospective analysis the Stockholm3 test and ancestry markers. Within this cohort the investigators will examine several predetermined risk factors to investigate their relationship to prostate cancer. This blood sample will be tested for quantitative levels of serum protein markers and DNA will be extracted and will be tested for germline mutations as defined by the Stockholm3 test and other ancestry informative markers. Results from the study will be presented in such a way that no individual information will be disclosed.
NCT05629494
Prostate cancer is the most frequently diagnosed cancer in men in the Unites States. Nearly 1 million prostate biopsy procedures are performed in the United States annually and elevated prostate-specific antigen (PSA) level is the primary reason for prostate biopsy in \> 90% of cases. However, at the PSA levels which trigger prostate biopsy, often no cancer is found in prostate biopsy specimens. PSA test can be elevated due to reasons other than cancer such as inflammation or natural variation in the level. Investigators plan to treat men with elevated PSA level with over the counter anti-inflammatory medications (ibuprofen, naproxen) to see if the PSA level will decrease to an acceptable level.
NCT04291664
This is a Phase I multi-center, open-label, study of DST-2970 to determine the MTD, overall safety/tolerability, PK/pharmacodynamic parameters, and efficacy in prostate cancer patients.The study will include a dose escalation phase followed by a dose expansion phase. Each cohort will consist of a "run-in" period to assess pharmacokinetic trough, as well as C1hour, C2hour, and C3hour levels of standard of care abiraterone acetate, followed by a minimum of an 80-hour washout (treatment delay), then initiation of treatment with DST-2970. The patient population that will be evaluated in this study include patients with castration sensitive or castration resistant prostate cancer who experience a rising PSA, with or without radiographic progression, while taking abiraterone acetate. In this protocol, "initial PSA response to abiraterone" is defined as having a ≥ 30% drop in PSA levels (confirmed by a second PSA level one month later) during the first 6 months of treatment with abiraterone. These patients who subsequently experience a rise in PSA while on abiraterone are considered as having "acquired resistance" to abiraterone in the context of this protocol. Patients not meeting the definition of having an "initial PSA response to abiraterone" are considered as having "primary resistance" to abiraterone in the context of the protocol. In the dose escalation phase, all patients with a rising PSA can be enrolled, whether they had an "initial PSA response to abiraterone" or never responded to abiraterone. Two expansion cohorts will be opened. One expansion cohort will evaluate patients who did achieve an "initial PSA response to abiraterone" within the first 6 months of treatment as defined above, but subsequently progressed by PSA with or without radiographic progression. A second expansion cohort will evaluate patients who did not achieve an "initial PSA response to abiraterone" as defined above but have PSA progression with or without radiographic progression. The rationale of the study is to determine if the better bioavailability of DST-2970 will overcome resistance to abiraterone acetate experienced in these two clinical settings. In all cohorts, treatment will continue until progressive disease, unacceptable toxicity, investigator and/or sponsor decision, intercurrent illness or patient withdrawal of consent. Patients will be monitored regularly with physical examination and laboratory tests.
NCT04716725
This phase II trial studies the use of 68Ga-PSMA-11 positron emission tomography (PET) in diagnosing patients with prostate cancer that continues to grow despite the surgical removal of the testes or medical intervention to block androgen production (castration resistant), and has spread to other places in the body (metastatic). 68Ga- PSMA-11 is a new imaging agent that may help get more detailed pictures of the tumor. This trial aims to see whether using 68Ga-PSMA-11 PET scans may help doctors learn more about where disease is located in the body.
NCT04605276
Rationale: Current imaging techniques for the detection and grading of prostate cancer are imperfect, leading to unnecessary biopsies, suboptimal treatment decisions and missed clinically significant cancers. The hypothesis of this study is that computer assisted analysis of 3D multiparametric ultrasound (mpUS) images can accurately detect, grade and localize prostate cancer. 3D mpUS may then become a more cost-effective and more streamlined imaging strategy than the current standard: mpMRI. Objective: The primary objective is to collect high-quality 3D mpUS and histology data, to train and improve the classifier algorithm with the goal of achieving an accurate ultrasound imaging tool for the detection of clinically significant prostate cancer. Secondary objectives are related to the preliminary assessment of the performance of 3D mpUS with computer assisted analysis. Study design: This is a prospective, multi-center study in men with a suspicion of prostate cancer who are scheduled for prostate biopsies, and men with confirmed prostate cancer who are scheduled to undergo a radical prostatectomy. Prior to prostate biopsies or the radical prostatectomy, 3D mpUS imaging will be performed. The ultrasound images will be analyzed and used for algorithm training using the biopsies and/or prostatecomy specimens as gold standard. Additional research coupes of pathology material (both biopsies and radical prostatectomy specimens) from study subjects will be anonymized and separately analyzed and stored in a central, independent institution. The outcome of the 3D mpUS analysis and the additional pathology evaluation are for research purposes only and will not interfere with standard patient care. Study population: 1) Male patients of age ≥18 suspected for prostate cancer who are scheduled for systematic and/or targeted biopsy after mpMRI examination. 2\) patients of age ≥18 with confirmed prostate cancer who are scheduled for radical prostatectomy. Main study parameters/endpoints: * Gleason/Grade group scoring based on histology. Using histology as the reference standard the accuracy of the algorithm will be optimized to be differentiating between benign tissue and various grades of malignancy. * Localization and size of lesions at full-gland histology in the subset of patients undergoing radical prostatectomy. Correlation in tumour size and location will be optimized between 3D mpUS findings and histology of the full gland. For the secondary objective, preliminary assessment of the performance of 3D mpUS, the following endpoints are evaluated * Among all clinically significant detected cancers confirmed by histology, the proportion of these cancers that would have been detected by 3D mpUS will be calculated. The number of false positive findings by 3D mpUS both as an absolute count and expressed as a mean rate per patient. * The concordance in the detection and grading of abnormalities between mpMRI and 3D mpUS by examining the frequency and type of disagreements and calculating the kappa statistic.

NCT05215574
Study of NGM831 as Monotherapy and in Combination with Pembrolizumab or Pembrolizumab and NGM438 in Advanced or Metastatic Solid Tumors
NCT05156905
The purpose of this study is to examine the safety and efficacy of cirmtuzumab in combination with standard of care docetaxel in patients with metastatic castration resistant prostate cancer. Docetaxel is a taxane chemotherapy which has been shown to prolong survival in men with castration resistant prostate cancer. Cirmtuzumab is a monoclonal antibody that targets the receptor called ROR1 of the non-canonical Wnt pathway and is suspected to contribute to prostate cancer growth and progression.
NCT06071195
Prior to treatment, it is essential to assess not only the extent of prostate cancer within the prostate, but also to determine whether the disease has initiated metastatic spread. Whole-body MRI has become a viable option for the detection of metastatic disease derived from a number of cancers, but is typically performed in a separate scanning session to an initial dedicated prostate MRI in which the local disease is assessed. In patients known to be at high risk for significant prostate cancer prior to this initial MRI, and thus highly likely to proceed to treatment, this delays arriving at a definitive treatment decision. The investigators will evaluate the sensitivity of a protocol that combines bi-parametric prostate MRI, performed according to PI-RADS v2.1 guidelines, with a whole-body MRI based on the METastasis Reporting and Data System for Prostate Cancer (MET-RADS-P) guidelines, for an All-in-One, local and systemic staging of intermediate-favorable or high risk prostate cancer patients. The resulting staging decisions will be compared to the results of systemic staging with those obtained by computed tomography and bone scintigraphy in the standard staging pathway.
NCT06614751
The primary objective of the study is to evaluate the safety, tolerability, PK, PD, and prilimary efficacy of a PARG inhibitor DAT-2645 in patients with advanced/metastatic solid tumors harboring BRCA1/2 loss of function alterations and/or other defects in the DNA damage repair (DDR) pathway.
NCT03177187

NCT04672460
This will be a Phase 1, open label, 2-sequence, crossover study to establish the BE of the current commercial formulation (Generation 3.1 talazoparib capsules) to the proposed talazoparib liquid-filled soft gelatin capsule (soft gel capsule) formulation after multiple dosing under fasting conditions in participants with advanced solid tumors. In addition, the effect of food on the PK of the proposed talazoparib soft gel capsule formulation will be evaluated in fixed sequence after the 2 BE assessment periods.
NCT06612580
68Ga-AAZTA-093 is a novel radiotracer incorporating a hypoxia sensitive nitroimidazole(NI)-moiety and a PSMA-targeting. In this study, we observed the safety, biodistribution, radiation dosimetry and diagnostic value of 68Ga-AAZTA-NI-093 PET/CT in patients with prostate cancer.
NCT04571840
This prospective clinical trial (PRostate Imaging using Mri +/- contrast Enhancement (PRIME)) aims to assess whether biparametric MRI (bpMRI) is non-inferior to multiparametric mpMRI (mpMRI) in the detection of clinically significant prostate cancer. This means that we are comparing MRI scans that requires injection of IV contrast (the current standard practice) versus MRI scans that can be performed without IV contrast in the detection of prostate cancer.
NCT06329830
The purpose of this research study is to test the safety and possible side effects of Lutetium-177 (177Lu)-Prostate-Specific Membrane Antigen (PSMA)-617 along with niraparib and abiraterone acetate plus prednisone when it is given to people diagnosed with metastatic castration-resistant prostate cancer (prostate cancer that has spread to other parts of the body and does not improve with hormonal therapies) at different dose levels. Once an optimal dose is selected, the researchers want to find out what how well these treatments work to improve survival and control the growth of the tumor.
NCT05931419
Prospective cohort study comparing robot-assisted radical prostatectomy and external beam radiotherapy combined with androgen deprivation therapy for high-risk non-metastatic prostate cancer in terms of health-related quality of life, functional outcomes, cost-effectiveness, progression-free survival and distant metastasis-free survival.
NCT06204341
The goal of this clinical trial is to combine several optimized treatments of high risk prostate cancer. The main question to answer is: is it safe to combine these optimized treatments. * patients will be irradiated on the prostate and (elective) lymph nodes more concentrated but with fewer hospital visits (hypofractionation) * the tumor will get a higher dose * androgen deprivation therapy will be reduced as much al possible preventing side effects Researchers will compare oncological outcome and toxicity.
NCT03473925
The purpose of this study is to assess the efficacy and safety of navarixin (MK-7123) in combination with pembrolizumab (MK-3475) in adults with one of three types of solid tumors: Programmed Death-Ligand 1 (PD-L1) positive refractory non-small cell lung cancer (NSCLC), castration resistant prostate cancer (CRPC) or microsatellite stable (MSS) colorectal cancer (CRC).
NCT06573736
Men meeting local clinical standard of care to undergo a prostate MRI for suspicion of prostate cancer will be included. Blood sample will be drawn on the day of MRI or immediately prior to MRI for measurement of the prostate cancer biomarker Stockholm3. Specifically, the Stockholm3 test will be performed in a retrospective manner and no clinical decisions will be made based on the results. The patients will not receive the results of the Stockholm3 assay. A Stockholm3 score will be reported for each patient. The primary aim is to show superior specificity of Stockholm3 (at different thresholds) for MRI selection compared to PSA (at different thresholds) (I.e., the proportion of men with a negative Stockholm3 test or a negative PSA test among those with a normal MRI). Additional aims: 1. To show non-inferior relative sensitivity in detection of csPC of Stockholm3 compared to PSA (The proportion of men with a positive Stockholm3 test (at different thresholds) or a positive PSA test (at different thresholds) among those diagnosed with csPC will be calculated). 2. To evaluate Stockholm3 risk thresholds to determine if it can be used to further reduce MRI, biopsy and Gleason grade group 1 cancers without reducing sensitivity of csPC detection.
NCT06325774
The aim of this trial is to study the safety outcomes of hypofractionated radiotherapy in treating patients with localized prostate cancer. Hypofractionated radiotherapy delivers higher doses of radiotherapy in a shorter time period, may enabling the killing of more tumor cells with fewer side effects. Accumulating evidence has proven the safety and feasibility of hypofractionated radiotherapy for localized prostate cancer.But for localized prostate cancer,the optimal dose per fraction of hypofractionated radiotherapy is still on its way.
