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.

Treatment & Imaging Metastatic Cancer

Researchers are looking for a better way to treat men who have metastatic castration-resistant prostate cancer (mCRPC). mCRPC is a cancer of the prostate (male reproductive gland found below the bladder) that has spread to other parts of the body. This type of prostate cancer does not respond to hormone treatment used to lower the level of testosterone, a male sex hormone, to prevent cancer from growing. The study treatment 225Ac-PSMA-Trillium, also called BAY3563254, is under development to treat advanced metastatic castration-resistant prostate cancer. It works by binding to PSMA and giving off radiation that can damage cancer cells and stop them from growing.

Imaging Diagnostic

This early phase I trial studies how well an image-guided prostate biopsy using the imaging agent 68Ga-prostate-specific membrane antigen (PSMA)-11 with a positron emission tomography/computed tomography (PET/CT) scan works in diagnosing prostate cancer in men with a prior negative or inconclusive prostate biopsy. PSMA is a protein that is found on the surface of prostate cancer cells. 68Ga-PSMA-11 is made up of a substance that binds to PSMA on tumor cells, linked with a radioactive substance that can then be seen on imaging scans such as PET/CT. 68Ga-PSMA-11 PET/CT-guided biopsy may help improve the detection rate of prostate cancer. This may help reduce over-diagnosis and over-treatment in men with low-risk prostate cancer and under-treatment in men with high-risk prostate cancer.

The flexible dosing schedule in the investigational arm, will be based on SPECT/CT response assessments obtained 24h after injection of LuPSMA therapy cycle. The response assessment during treatment holiday period will be based on PET/CT every 12 weeks.

A Feasibility Study of Hypoxia Imaging in Patients With Prostate Cancer Using Positron Emission Tomography (PET) With 18F-Fluoroazomycin Arabinoside (18F-FAZA)

The purpose of this study is to look for low levels of oxygen (hypoxia) in prostate cancer using a special x-ray test called a positron emission tomography (PET)scan. Hypoxia may have an effect on how prostate cancer grows and responds to treatments like radiotherapy and chemotherapy. The use of PET scans to measure hypoxia may be better and simpler than the methods used previously.

Fluorine-18 - 2-(3-(1-carboxy-5-[(6-[18F]Fluoro-pyridine-3-carbonyl)-Amino]-Pentyl)-Ureido)-Pentanedioic Acid (18F-DCFPyL) Positron Emission Tomography / Computed Tomography (PET/CT) for Assessment of Recurrent Prostate Cancer

Prostate cancer (PC) is the third most common cause of cancer death in men. Most patients with localized PC will be cured with surgery or radiation therapy, but up to 35% of patients will have their PC 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 (PSA) levels. This study proposes to use Fluorine-18-2-(3-(1-carboxy-5-[(6-[18F]fluoro-pyridine-3-carbonyl)-amino]-pentyl)-ureido)-pentanedioic acid (18F-DCFPyL) Positron Emission Tomography / Computer Tomography (PET/CT) scans which targets prostate-specific membrane antigens (PSMA) to detect where in the body the PC has recurred.

PSMA-based 18F-DCFPyL PET/CT and PET/MRI Pilot Studies in Prostate Cancer

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.

Prostate Specific Membrane Antigen (PSMA) or Fluciclovine (FACBC) PET/CT Site-Directed Therapy of OLigometASTatic Prostate Cancer (P-Flu-BLAST-PC): A Multicenter Study

OUTLINE: Patients are assigned to 1 of 3 groups. GROUP I: Patients for whom initial fluciclovine or PSMA PET/CT does not reveal any abnormalities outside the prostatic fossa undergo PSA rechecks every 3 months, and undergo fluciclovine or PSMA PET/CT once PSA is > 2 ng/ml. If still no abnormalities are found outside of the prostatic fossa, patients continue to undergo PSA rechecks every 3 months, and undergo fluciclovine or PSMA PET/CT once PSA is > 5 ng/ml. Patients are off study for treatment plan once PSA reaches 10 ng/ml. GROUP II: Patients undergo fluciclovine or PSMA PET/CT and who have =< 3 regions of metastatic disease outside of the prostatic fossa that are amenable to metastasis-directed therapy undergo lymphadenectomy or radiation therapy. Six to ten weeks after surgery, patients receive abiraterone acetate 1000 mg orally (PO) once daily (QD) and prednisone PO QD. Treatment repeats every 4 weeks for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients may start radiation therapy after 2 cycles of abiraterone acetate and prednisone. GROUP III: Patients undergo fluciclovine or PSMA PET/CT and who have > 3 regions of metastatic disease receive abiraterone acetate and prednisone as in Group II. After completion of study treatment, patients are followed up at 37, 49, 61, 73, 85, 97, 109, and 121 weeks, at 36, 42, 48, 54, 60, and 66 months, and then annually thereafter.

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, β 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.

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 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.

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.

Minority-Inclusive Imaging Biomarker-Based End of Therapy Trial for 177Lu-PSMA-617, a Randomized De-Escalation Theranostic Trial for Metastatic Castrate Resistant Prostate Cancer

This phase II trial studies how to improve the usage of Lu 177 vipivotide tetraxetan (177Lu-prostate-specific membrane antigen [PSMA]-617) for treating patients with castration-resistant prostate cancer that has spread from where it first started (primary site), to other places in the body (metastatic) utilizing a treatment pause after 5 cycles of therapy versus standard continuous treatment for 6 cycles. Lutetium is a radioligand therapy (RLT). RLT uses a small molecule (in this case 177Lu-PSMA-617) that carries a radioactive component to destroy tumor cells. When lutetium is injected into the body, it attaches to the PSMA receptor found on tumor cells. After lutetium attaches to the PSMA receptor, its radiation component destroys the tumor cell. Giving 177Lu-PSMA-617 for 5 cycles versus 6 cycles may better treat patients with metastatic castrate resistant prostate cancer.

A Multicenter Study Evaluating the Diagnostic Value of 68Ga-MY6349 PET/CT for Prostate Cancer

The main objective of this research is to develop and evaluate new PET imaging agents with high sensitivity and specificity for prostate cancer and other aggressive tumors. Specifically, the research focuses on improving upon existing prostate cancer imaging methods, such as PSA tests and PSMA PET/CT, which have limitations in sensitivity, specificity, and the ability to provide comprehensive tumor information，and aims to create a novel PET probe targeting Trop2, an antigen highly expressed in multiple cancer types, to enable in vivo, whole-tumor assessment. This would support early diagnosis, more precise staging, and effective monitoring of cancer therapy.

Usefulness of Tumor Heterogeneity Assessment in Patients With MCRPC Undergoing Radioligand Therapy With 177LU-PSMA-617 Using Serial 18F-DCFPYL, 18F-FDG and 18F-Fluciclovine PET/CT Predicting Clinical Outcome

The imaging analysis will consist in obtaining quantitative measurements of lesion uptake on the pre- and post-LuPSMA RLT (lesion and whole-body SUVmax, SUVmean and tumor volume) at each time point on all PET/CT scans. PET metrics at the lesion- and whole-body level will be compared among different PET radiopharmaceuticals at the same time point, and changes over time will be assessed.

Subjects will be treated in cohorts at three sequential target absorbed radiation dose levels, where the dose level for the next cohort will be determined by a prespecified decision tree for escalation/de-escalation, according to the accelerated Time-to-Event Bayesian Optimal Interval Design (TITE-BOIN) approach.

The VOYAGER Study is an interventional, non-randomized, single-arm, dose escalation trial with the goal of determining the safety of TheraSphere PCa device in patients with clinically localized prostate cancer across US-based centers.

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.

Feasibility Study on the Use of PET-MRI / 68Ga-PSMA Imaging for HIFU-focal Treatment in the Event of Recurrent Prostate Cancer After Radiotherapy - PSMA Study

A significant proportion of patients with localized prostate cancer, and treated for curative intent by radiotherapy, have a local recurrence. Among these patients with local recurrence, few receive curative remedial treatment but most of them are treated with palliative hormonal therapy without any chance of long-term recovery.

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.

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.
