Treatment Locally Advanced Cancer
Researchers are looking for a better way to treat people who have advanced metastatic castration-resistant prostate cancer (mCRPC). The study treatment actinium-225-macropa-pelgifatamab (also called 225Ac-pelgi or BAY3546828) is a new type of treatment under development for men with mCRPC who have already received available treatments or have few treatment options available. It works by binding to a protein on the surface of the cancer cells called prostate specific membrane antigen (PSMA). As it gives off a type of radioactivity that travels a very short distance, it kills the nearby (cancer) cells that express PSMA.

A Prospective Pilot Study Investigating rhPSMA 7.3 PET/MRI in Detecting Recurrent Disease and Aid in Radiotherapy Planning in Patients With Biochemically Recurrent Prostate Cancer
prostate-specific antigen (PSA) following prostate surgery (biochemically recurrent). An increase in PSA levels alone does not tell the doctor where the cancer may be or how much cancer there may be. Imaging tests, like a bone scan, MRI, and/or computed tomography, are often performed to help the doctor learn where or how much cancer there is, and how best to treat the cancer. rhPSMA-7.3 is a radioactive tracer agent that when used with PET/MRI imaging may help diagnose and look for the spread of prostate cancer. Prostate-specific membrane antigen (PSMA) is a protein that is expressed in prostate cancer and this agent targets the PSMA molecule. Giving rh PSMA 7.3 during PET/MRI may help doctors better find where the cancer may be spreading and how much of it there is. The results of this trial may also guide in radiotherapy planning.

Optimizing Timing of rhPSMA-7.3 (18F) for Assessing Site(s) of Recurrent Disease Following Radical Prostatectomy
All men following Radical Prostatectomy (RP) at NYU Langone Health undergo routine prostate specific antigen (PSA) testing in order to identify disease recurrence. By consensus, a BCR following RP occurs once the PSA > 0.2 ng/ml/ Biochemical recurrence often develops years prior to clinical evidence of disease recurrence. Early identification of the site(s) of disease recurrence enables early salvage intervention. Men will be eligible for the study at the point in time their post-prostatectomy PSA level first becomes >0.2 ng/ml. Only those patients with rhPSMA-7.3 (18F) identifiable disease (local, nodal or systemic) will be offered salvage intervention per standard of care. All patients with a negative initial rhPSMA-7.3 (18F) scan will undergo a second scan when the PSA is > 0,5 ng/ml or one year after the initial PET study. The salvage interventions will be at the discretion of the investigator. The study will compare the diagnostic yield of the first and second rhPSMA-7.3 (18F) studies.

A Head-to-head Comparison of 68Ga-P15-041 and 68Ga-PSMA-11 PET/CT Imaging in the Same Group of Prostate Bone Metastasis
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.

A Phase II Study of Fluorine-18 (18F)-Labeled PSMA-1007 in Patients With Known or Suspected Metastatic Prostatic Carcinoma
A [18]F-PSMA-1007 PET/CT or PET/MRI scan are nuclear medicine tests used to create pictures of the whole body that may show where cells that express Prostate-Specific Membrane Antigen (PSMA) are found. PSMA is a transmembrane protein that is overexpressed in the majority of prostate cancers. PSMA imaging utilizes this overexpression, by binding on the transmembrane receptor and internalization in the cancer cells. The internalized isotope can then be imaged with the use of a PET/CT or PET/MRI scanner and show where cancer cells may be present in the body. This imaging modality has been shown to be superior to conventional imaging, such as bone scan and CT, in the detection of prostate cancer tumors.

Diagnostic Performance of 18F-prostate-specific Membrane Antigen-1007 PET/CT in the Detection of Prostate Cancer
Currently, Maximum Standardized Uptake Value (SUVmax) is the most commonly used semi-quantitative parameter in PET/CT, which is used to assess tumor burden of PCa, and thus can be used as an imaging biomarker to assess the degree of malignancy of prostate cancers. However, prior studies mainly focused on the correlation between patients' biochemical recurrence lesions and the PSA levels and Gleason score. There is a lack of research to explore the correlation among primary PCa burden, PSA levels, and the degree of prostate cancer malignancy. The aim of this project is to use 18F-PSMA PET/CT SUVmax to analyze the correlation among primary PCa imaging, and clinical indicators, and to evaluate the predictive value for PCa risk stratification, metastasis risk, and biochemical recurrence.

Phase II Study: [18F]DCFPyL PET/MRI for Personalizing Prostate Cancer Subclinical Metastatic Ablative MR-guided Radiotherapy (MRgRT)
In the clinical scenario of recurrent prostate cancer (PCa) post local therapy, current standard studies (bone scan and computed tomography) commonly fail to identify the recurrent disease location. In this study the investigator aims to prospectively map recurrent disease with the unique combination of whole-body MR anatomical imaging combined with a new high-sensitivity and PCa-specific PET probe (PSMA-targeted: [18F]DCFPyL) to provide precise localization information to target disseminated tumor deposits in men presenting with rising PSA after prostatectomy and radiotherapy (maximal local therapies). Moreover, we will consequently treat all identified disease with image-guided stereotactic ablative radiotherapy (SABR), which has shown tantalizing results achieving excellent tumor eradication rates with minimal toxicities. This study is uniquely positioned to enable the discovery of new biomarkers and the correlation of prognostic tests (e.g. genomic signatures) from the initial prostatectomy specimen with the PET-MR/CT imaging results and curative-intent treatment outcomes. The significance of the proposed work towards a measurable impact in PCa care is important to emphasize. The study team believes this novel curative-intent approach will transform lives, as opposed to therapies that transiently impact incurable disease stages. Herein, the focus is on patients at the earliest point of the disease spectrum of recurrent PCa after curative-intent treatments. Our hypothesis is that PSMA-targeted [18F]DCFPyL PET-MR/CT allows earlier detection and localization of defined metastatic targets in these patients, at a stage amenable to image-guided curative-intent therapy.

68Ga-PSMA-11 Positron Emission Tomography / Computed Tomography (PET/CT) for Assessment of High Risk or Recurrent Prostate Cancer
Prostate cancer is the third most common cause of cancer death in men. Most patients with localized prostate cancer will be cured with surgery or radiation therapy, but up to 35% of patients will have their prostate cancer return. Whether it has returned locally or distantly determines which type of treatment they will receive. Current conventional imaging modalities have limitations particularly at low prostate specific antigen levels. This study proposes to use Gallium-68-PSMA-11 (68Ga-PSMA-11) Positron Emission Tomography / Computer Tomography (PET/CT) scans which targets prostate-specific membrane antigens (PSMA) to detect where in the body the prostate cancer has recurred.

A Sub-study of 18F-DCFPyL Positron Emission Tomography / Computed Tomography (PET/CT) for Assessment of Recurrent Prostate Cancer Evaluation of the Safety and Sensitivity of 68Ga-DOTATOC PET/CT for Imaging NET Patients
Quantitative parameters obtained with dynamic whole body imaging using positron emission tomography (PET) can provide additional and complementary information to standard PET. Dynamic imaging allows for better understanding of the behavior of the radio-pharmaceutical because it can be followed over time. Thought to be difficult to perform with currently available clinical equipment that can affect the clinical workflow, it has recently shown to be feasible. We want to test the feasibility of this imaging technique and evaluate its utility in identifying lesions with three different radio-pharmaceuticals as compared to standard static PET. This study will also determine the clinical impact of DWB PET on participant management by comparing the overall qualitative assessment performed by nuclear medicine physicians between the standard PET images and the DWB ones.

The Correlation Between the Detection Rate of 18F-FACBC PET/CT and the PSA Kinetics for Prostate Cancer Patients With Biochemical Recurrence.
Prostate cancer (PCa) is the fifth-most common cancer for male with a seventh highest cancer-related death in Taiwan. Currently, the incidence and mortality rate are still increasing rapidly. The treatment decision planning is made up by clinical charts like Gleason score (GS), TNM stage and serum prostate-specific antigen (PSA) level. However, after definitive therapy for PCa with either external beam radiotherapy (EBRT) or radical prostatectomy (RP), up to half patients experience biochemical recurrence (BCR). Although not all patients with BCR proceed to develop disease progression, it is important to identify early lesion to initiate salvage treatment.

Lutetium-177-PSMA-617 Radioligand Therapy in Oligo-metastatic Hormone Sensitive Prostate Cancer.
Radioligand therapy (RLT) using Lutetium-177 labelled PSMA is a promising new therapeutic approach to treat metastatic prostate cancer. This tumor-specific treatment is directed against prostate-specific membrane antigen (PSMA), which is overexpressed in prostate cancer cells. In the last few years, several lutetium-177 (177Lu, ฮฒ emitter) labeled PSMA ligands have been developed and are currently applied to treat metastatic castrate resistant prostate cancer patients. To date, there are no prospective randomized studies published using this treatment in the hormone sensitive setting or in oligometastatic prostate cancer. Therefore, this study we will evaluate the effect of 177Lu-PSMA in patients with hormone sensitive oligo-metastatic prostate cancer.

A Randomized Trial Comparing Conventional "Salvage" Radiotherapy and Individualized 68Ga-PSMA-11 or 18F-PSMA-1007 PET/CT Targeted Treatment in Patients With Biochemical Recurrence After Prostate Cancer Surgery
Less than 50% of patients receiving salvage radiation therapy (SRT) to the pelvis as treatment for prostate cancer relapsing after surgery will achieve undetectable Prostate Specific Antigen (PSA) levels. Despite SRT, two-thirds of patients will again develop elevated PSA, 20% will have distant metastases, and 10% will die from prostate cancer within 10 years. The reason for this is probably preexisting distant metastasis and lymph node metastasises which need to better targeted directly. Additionally , there are well known permanent side effects to SRT. Standard imaging techniques have poor sensitivity detecting recurrence when PSA is below 1.0 ng/ml. The surface protein Prostate-specific membrane antigen (PSMA) is overexpressed on prostate cancer cells and 68Gallium (68Ga)- and 18Fluorine (18F)-targeted radioligands have been developed. PSMA PET/CT is used increasingly but there is limited data of its impact. In this study patients with biochemical relapse of prostate cancer after surgery are randomised to the control or experimental group (1:2) and undergo a PSMA PET/CT scan. The experimental group receives individualised therapy based on the result of the PET/CT. The control group receives standard salvage therapy and the result of the PET/CT is blinded. The patients are followed-up with PSA test and quality of life questionnaires.

Multicenter Evaluation of Diagnostic Performance of [18F]FPSMA-1007 PET/CT in Patients With Suspected Prostate Cancer
The diagnostic tools for detecting patients with early prostate cancer are limited due to poor diagnostic performance. The positron emission tomography (PET) combination with the diagnostic radiopharmacy is a non-invasive tool to provide the molecular imaging of the whole body and offer more comprehensive physiological information and then can raise the diagnostic performance. Prostate-specific membrane antigen (PSMA)-targeting pharmaceuticals have been regarded as the most promising diagnostic tool to diagnose patients with prostate cancer. Currently, the 18F-PSMA-1007 as PSMA-targeting 18F-radiolabeled pharmaceuticals have developed and successfully used in patients with intermittent- and high-risk prostate cancer or recurrent prostate cancer. The study aims to understand the diagnostic performance of 18F-PSMA-1007 PET/CT in different-stage prostate cancer patients by initiating the first multicenter clinical trial of 18F-PSMA-1007 in Taiwan.

Monocentric Observational Study on the Diagnostic and Prognostic Role of 18F-PSMA PET (PET/CT and PET/MR) in Prostate Cancer
The general objective of this retrospective and prospective study is to evaluate the diagnostic and prognostic role of a quantitative analysis of PET images with 18F-PSMA in all stages of the disease in patients with prostate cancer. To this end, both imaging parameters commonly used in clinical practice and the contribution of radiomic features will be investigated. The latter are quantitative features extracted from biomedical images, and are believed to be able to provide information, otherwise impossible to investigate, useful for the characterization of various pathologies. This methodology is very promising, but also recent and therefore little studied and standardized. Our objective is also to investigate how to optimize it from a purely methodological point of view.

A Phase 1/2 Study of Combination Olaparib and Radium-223 in Men With Metastatic Castration-Resistant Prostate Cancer With Bone Metastases (COMRADE)
This phase I/II trial studies the best dose and side effects of olaparib and how well it works with radium Ra 223 dichloride in treating patients with castration-resistant prostate cancer that has spread to the bone and other places in the body (metastatic). PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Radioactive drugs, such as radium Ra 223 dichloride, may carry radiation directly to tumor cells and not harm normal cells. Giving olaparib and radium Ra 223 dichloride may help treat patients with castration-resistant prostate cancer.

Strategy to Reduce Bladder Activity With RhPSMA 7.3: Comparison of 18F-RhPSMA 7.3 PET/CT With and Without Furosemide in Biochemical Recurrence of Prostate Cancer
This phase II trial evaluates Fluorine-18 radiohybrid prostate-specific membrane antigen (18F- rhPSMA)-7.3 positron emission tomography (PET)/computed tomography (CT) scans with and without furosemide for the reduction of bladder activity in patients with prostate cancer that has come back (recurrent) based on elevated levels of prostate-specific antigen (PSA) in the blood (biochemical) after prostate surgery (prostatectomy). Furosemide is a diuretic substance that increases the urine flow into the bladder, thereby decreasing the level of radioactivity within the bladder, which may help to see any abnormal areas that could be masked by the radioactivity within the bladder. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, rhPSMA ligand. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. Adding furosemide to 18F-rhPSMA 7.3 PET/CT scans may help to better detect and treat patients with biochemically recurrent prostate cancer.

A Phase 2 Trial of Radium Ra 223 Dichloride in Combination With Androgen Deprivation Therapy and Stereotactic Body Radiation Therapy for Patients With Oligometastatic Castration Sensitive Prostate Cancer
This phase 2 trial studies radium Ra 223 dichloride, hormone therapy and stereotactic body radiation in treating patients with prostate cancer that has spread to other places in the body. Radium Ra 223 dichloride contains a radioactive substance that collects in the bone and gives off radiation that may kill cancer cells. Hormone therapy using leuprolide acetate or goserelin acetate may fight prostate cancer by lowering the amount of testosterone the body makes. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. Giving radium Ra 223 dichloride, hormone therapy and stereotactic body radiation may work better at treating prostate cancer.

Radium-223 Combined With Dexamethasone as First-line Therapy in Patients With Metastatic Castrate Resistant Prostate Cancer
The purpose of this study is to determine whether an oral drug called dexamethasone (a corticosteroid) given together with radium-223 may control PSA levels and reduce side effects during radium-223 treatment. Corticosteroids are anti-inflammatory medicines prescribed for a broad range of conditions and are widely used in conjunction with chemotherapy treatments for cancer. Prior research studies have shown that dexamethasone reduces PSA levels by lowering the production of androgens (i.e. male hormones) and improves overall tolerance for cancer-fighting drugs and therapies. Up to 24 men being treated with radium-223 at University Health Network will be enrolled into this study. If the study is positive, it might offer an improved quality of life and extended survival.

Retrospective Analysis of 68Ga-PSMA-PET in Patients With Prostate Cancer: Experience From Brazil (LACOG pPR015)
Gallium-68-prostate-specific membrane antigen (68Ga-PSMA) positron emission tomography (PET) has been increasingly used in the management of PCa in Brazil. Thus, the detection of metastatic lesions is improved over traditional methods e.g. MRI and the diagnosis of mCSPC patients has been proportionally increasing. Due to a lack of guidelines and clinical trials including 68Ga-PSMA-PET imaging, the management of these patients is extrapolated from data based on conventional imaging. Treatment decision and duration of treatment for mCSPC patients based on 68Ga-PSMA-PET imaging is currently unknown. 68Ga-PSMA-PET allows a diagnosis of a different set of low volume oligo-metastatic prostate cancer patients. Based on that, a new gap has been built up, since there are no standards of how those patients are managed and how they respond to conventional therapies, to metastasis direct therapy or even if they could be spared of any treatment, reducing costs and toxicities. This patient population has not been included in clinical trials and its critical to generate information on the diagnosis, treatment and outcome of these patients in clinical practice.
