Prostatic Neoplasms

Researchers are looking for new ways to treat metastatic castration-resistant prostate cancer (mCRPC). Researchers have designed a study medicine called ifinatamab deruxtecan (also called I-DXd or MK-2400) to treat mCRPC. The goal of this study is to learn if people who receive I-DXd live longer overall and live longer without the cancer growing or spreading than people who receive chemotherapy.

The goal of study： The study has two parts: Part 1 Dose Escalation and Part 2 Dose Expansion. In Part 1, a few participants will receive the lowest dose of study drug. The study team will make sure it is safe and tolerated before enrolling new participants at a higher dose of study drug. There will be up to six or more dose levels of study drug tested (called cohorts). Which dose you receive will depend on how many participants have taken part in the study before you. The purpose of Part 1 of the study is to evaluate the safety of the study drug at different dose levels, to understand what your body does to the study drug, and to find the best dose of study drug in people who have advanced solid tumor cancers. In Part 2, participants will receive the best dose level that was determined in Part 1 of the study. The purpose of Part 2 of the study is to evaluate the safety of the study drug at the dose level determined in Part 1, to understand what your body does to the study drug, and to see how your cancer responds to the study drug. Participants will: Participants will have 17 or more visits to the study centre. This study has a screening phase of up to 28 days , and a treatment phase with cycles of 21 days each. Participants will also have an End of Treatment (EOT) visit 21 days after the final study drug treatment, and a Follow-up visit 30 days after the EOT visit . Participants will be contacted by telephone every 3 months after the Follow-up visit to check on the wellbeing and record any new anticancer therapy they may have started.

Background: Research studies have shown that genetic changes and family history may increase a man s risk for prostate cancer. Researchers want to follow the prostate health of men who have specific genetic changes associated with prostate cancer to help them learn more about which men are at higher risk for prostate cancer. Objectives: To study men with specific genetic changes and determine who is at higher risk for getting prostate cancer. To study if certain genetic changes and family history can be used to help prevent or treat prostate cancer. Eligibility: Males between ages 30-75 who have one or more specific genetic changes but without prostate cancer. Design: * This study does not perform genetic testing. All participants must have documented genetic changes and able to provide a copy of the report. * Before enrollment, participants will provide a copy of documented genetic changes and go through a telephone interview to determine eligibility for the study. * On enrollment, participants will have medical and family history review, medication review, physical exam, blood collection for clinical and research testing, and MRI (magnetic resonance imaging) of the prostate. * Every year, participants will repeat the physical exam, medical history, family history, medication review, routine blood tests, including PSA and testosterone. * Every 2 years, participants will repeat all the above plus prostate MRI and blood tests for research. * If, at any time, the physical exam, blood tests or MRI are abnormal, participants may be asked to do a biopsy. * If the biopsy results in prostate cancer, participants will be given counseling on next steps, general treatment recommendations, and then followed with a phone call each year. * Participants may ask to speak with a genetic counselor....

Study Overview This research compares two types of post-operative salvage radiotherapy (SRT) for men with prostate cancer who have had surgery but show signs of recurrence (detectable PSA). The goal is to see if a shorter treatment schedule is as safe and effective as the standard schedule. Why is this study important? After prostate surgery, cancer can return in up to 70-80% of high-risk patients. Radiotherapy helps control this, but the best way to deliver it-especially the number of sessions and whether to treat the pelvic area-is still being studied. Shorter treatments could mean less time in therapy and better quality of life, if such treatments are proven safe. What is being compared? Standard treatment (Arm A): 25 sessions (about 5 weeks) Prostate bed: 62.5 Gy Pelvis: 45 Gy Shorter treatment (Arm B): 20 sessions (about 4 weeks) Prostate bed: 52.5 Gy Pelvis: 43 Gy Both groups may also receive hormone therapy (ADT) for 6-24 months. Main Goal To check if the shorter treatment causes no more side effects (urinary or bowel problems) than the standard treatment, while keeping cancer control similar. Other Things to be Measured Cancer control (PSA levels, spread of disease) Survival Quality of life (urinary, bowel, sexual health questionnaires) Who can join? Men who: Had prostate surgery Have a detectable PSA (≥0.2 ng/mL) No distant metastasis Are in good general health (ECOG 0-2) How long will the study last? About 12 years total: 2 years to enroll patients 10 years of follow-up

Background: \- Radiation is a common treatment for prostate cancer. It helps damage tumor cells and causes them to die. Radiation can be effective, but some tumors may be harder to treat with radiation or even with surgery. This happens to a small number of men who have either radiation or surgery for prostate cancer. Most men who have these hard-to-treat tumors do not know if the tumor has recurred only in the prostate or has spread to another area. Also, men whose prostate cancer has recurred only after radiation may have different treatment options. This study will use improved imaging studies to better understand why some men do not respond as well to initial radiation treatments. Objectives: \- To use detailed imaging studies to look at the results of local radiation therapy for prostate cancer. Eligibility: * Men at least 18 years of age who are scheduled to have radiation for prostate cancer. * Men at least 18 years of age whose prostate cancer has returned after earlier treatments. Design: * All participants will have a medical history and physical exam. Blood and urine samples will be collected. Imaging studies will be used to evaluate the cancer at the start of the study. * All participants will have an initial full magnetic resonance imaging (MRI) scan of the prostate. Tumor and healthy tissue samples will be collected. * Those whose cancer has recurred after treatment will discuss possible treatment options with the study doctors. * Participants who are scheduled to have radiation will have radiation therapy. This will be given according to the current standard of treatment. * After radiation, participants will have regular follow-up tests and imaging studies. They will have another full MRI scan 6 months after the end of radiation treatment.

Background: The current standard treatment of prostate cancer is either surgery or radiation. Typically, this includes either the removal or radiation of the whole prostate gland. Many people now seek out focal therapy options to decrease the side effects of treatment. Until now, several forms of physical destruction with heat (thermal ablation), cold (cryotherapy), sound waves (HIFU), laser (FLA), and electrical energy (IRE). A new type of radiation (SBRT) may be an effective way to cure men of early-stage prostate cancer with fewer side effects than standard treatments. Objective: To see how people with untreated localized prostate cancer will respond to focal therapy with SBRT. Eligibility: People aged 18 years and older with untreated localized prostate cancer (prostate cancer which has not spread outside of the prostate gland). Design: * Participants will undergo screening including blood tests, an MRI, a PSMA PET/CT (18F-DCFPyL), and a biopsy. * Small, non-radioactive, gold seeds about the size of a grain of rice will be placed in and/or around the tumor to help target the radiation treatment. * Radiation (SBRT) will occur in 2 separate sessions about 1 week apart. No sedation is used, these sessions are painless. Each session will take about 1-2 hours. Participants can go home afterwards. * Follow-up will continue for 2 years with repeat scans (MRI and PSMA PET/CT) and blood (PSA) tests. * After two years, a biopsy will be done to understand the impact of this new treatment on prostate cancer.

This study is a randomized controlled field experiment embedded in the medical institution Early Diagnosis Program in Chile. Participants with two exams pending (a cancer screening test and a chronic disease test for diabetes and dyslipidemia) will be randomly assigned across a 3 × 3 factorial design: three message framing conditions (Basic, Risk/Importance, Peace of Mind) crossed with three exam-type conditions (cancer screening only, chronic disease test only, or both exams). Participants with only a cancer screening pending will be assigned to the 3 framing conditions and be encouraged to get the cancer screening. In both cases, participants are assigned to each experimental arm at twice the rate of an additional arm receiving the standard message currently used by the medical institution. This standard-message arm is included for operational purposes, is not part of the pre-specified analyses, and is thus not described in the "Arms and Intervention" section (or counted for "number of arms").

The purpose of this study is to assess the efficacy and safety of opevesostat plus hormone replacement therapy (HRT) compared to alternative abiraterone acetate or enzalutamide in participants with Metastatic Castration-resistant Prostate Cancer (mCRPC) previously treated with one next-generation hormonal agent (NHA). The primary study hypothesis is that opevesostat is superior to alternative abiraterone acetate or enzalutamide with respect to radiographic progression free survival (rPFS) per Prostate Cancer Working Group (PCWG) Modified Response Evaluation Criteria in Solid Tumors (RECIST 1.1), as assessed by Blinded Independent Central Review (BICR), in androgen receptor ligand binding domain (AR LBD) mutation positive and negative participants.

Background: * It is not fully understood why prostate cancer in some men becomes androgen-independent (no longer responds to anti-androgen medication), but genetics likely plays an important role. * Genes contain the hereditary information that is passed down from parents to children. Although everyone has the same set of genes, individuals can have different forms of the same gene. * Differences in genes may explain, at least in part, why some people develop a more aggressive form of prostate cancer than others. Objectives: -To obtain blood samples from patients with prostate cancer to try to identify gene differences associated with progression to the androgen independent state. Eligibility: -All participants participating in NCI prostate cancer protocols. Design: * Participants with prostate cancer are evaluated in the NCI s Medical Oncology Clinic. * Blood samples are collected at the initial visit or at follow-up visits. * DNA (genetic material) and white blood cells are extracted from these samples to be used for genotyping and establishment of cell lines. * Gene variations are correlated with prostate cancer prognosis and prognostic indicators.

This is a Phase 2 study of GV20-0251 in combination with anti-PD-1 monoclonal antibodies (including tislelizumab and toripalimab) for the treatment of participants with unresectable, locally advanced, or metastatic solid tumors who are refractory to, intolerant of, or ineligible for standard of care.

This study aims to explore the real-world treatment adherence, persistence of apalutamide, and assess the risk of non-adherence according to the participant's profile and behavior of metastatic hormone-sensitive prostate cancer (mHSPC) participants treated with apalutamide during the first year of continued treatment.

The purpose of this study is to identify the recommended phase 2 combination dose (RP2CD) of Pasritamig in combination with JNJ-86974680 in Part 1 (Dose finding) of the study and to determine how safe and tolerable the RP2CD is for treatment of participants with advanced prostate cancer in Part 2 (Dose expansion) of study.

The purpose of this study is to identify the recommended phase 2 combination dose (RP2CD) of JNJ-78278343 in combination with JNJ-95298177 in Part 1 (Dose confirmation) of the study and to determine how safe and tolerable the RP2CD is for treatment of participants with metastatic castration-resistant prostate cancer (mCRPC; a stage of prostate cancer where the cancer has spread beyond the prostate and is resistant to hormonal therapy) in Part 2 (Dose expansion) of study.

The purpose of Parts 1, 2A, and 2B of the study is to determine the recommended regimen for Phase 2 (RP2Rs) of combination of JNJ-87189401 with JNJ-78278343 and the purpose of Part 2C of this study is to determine how safe the RP2R(s) of the combination of JNJ-87189401 and JNJ-78278343 is, with or without apalutamide. Part 3 of this study evaluates the safety of the triplet combination of JNJ-87189401 and JNJ-78278343 with standard of care (SOC) lutetium Lu-177 vipivotide tetraxetan. Part 4 of this study further evaluates the safety of the triplet combination of JNJ-87189401 and JNJ-78278343 with JNJ-101556143 in participants with advanced prostate cancer.

The aim for this study is to assess the diagnostic performance of 64Cu-SAR-bisPSMA PET to detect regional nodal metastases.

To determine the dose, safety, radiation dosimetry and efficacy of 177Lu-rhPSMA-10.1 in participants with PSMA-expressing metastatic castrate resistant prostate cancer.

The goal of this clinical trial is to learn if a low to moderate load power training program is feasible and effective for improving fitness and quality of life of people with prostate cancer under androgen suppression therapy and bone or lymph node metastasis. The main questions it aims to answer are: * Does a low to moderate load power training program improve quality of life in people with metastatic prostate cancer under androgen deprivation therapy? * Does a low to moderate load power training program improve power, strength, endurance, and balance in people with metastatic prostate cancer under androgen deprivation therapy? Researchers will compare the exercise program with routine care to see if power training works to improve common physical side effects of androgen suppression therapy in patients with metastatic prostate cancer. Participants will: * Participate in a supervised exercise program twice a week for 6 months or maintain routine care. * Perform fitness tests and questionnaires about quality of life and mental health. * Those who take part in the exercise program will also perform semi-structured in-depth interviews after the end of the program.

Prostate cancer is the most common non-skin cancer among men in the United States. For some men, the cancer has already spread to other parts of the body at the time of diagnosis; this is called metastatic hormone-sensitive prostate cancer (mHSPC). Treatment for mHSPC has advanced significantly, with new standards of care involving androgen deprivation therapy (ADT) combined with drugs known as androgen receptor pathway inhibitors (ARPIs), sometimes alongside chemotherapy like docetaxel. Darolutamide is an ARPI that is approved by the FDA for treating mHSPC in a "triplet" combination with ADT and docetaxel. It is also used in a "doublet" combination with ADT alone. However, there is limited information on how darolutamide is used in real-world clinical settings for this condition, which creates a gap in knowledge for making treatment decisions. This study aims to fill that gap by analyzing real-world data from electronic medical records. The primary goal is to describe the characteristics of patients with newly diagnosed mHSPC who are treated with darolutamide (either as a doublet or triplet) in urology clinics across the US. The study will also examine drug use patterns and clinical outcomes for these patients. Additionally, the study will explore the characteristics of patients treated with other ARPIs (abiraterone acetate, enzalutamide, and apalutamide) and assess the feasibility of creating matched patient groups for future comparative research. Data will be collected retrospectively from a large network of community urology practices in the US.

This investigator-initiated, prospective study evaluates the diagnostic utility of rhPSMA-7.3 (¹⁸F) PET/CT (flotufolastat F18, marketed as POSLUMA®) in men with biopsy-proven, low-risk or favorable intermediate-risk prostate cancer managed with active surveillance. The study aims to determine whether the addition of PSMA-based PET/CT to standard multiparametric MRI (mpMRI) improves detection of clinically significant prostate cancer compared to MRI alone. Eligible participants will undergo rhPSMA-7.3 (¹⁸F) PET/CT and mpMRI prior to confirmatory prostate biopsy. Biopsies will target areas identified on MRI, PET/CT, or both, and histopathologic outcomes will serve as the reference standard. The study will assess lesion-level concordance between PET/CT, MRI, and pathology, and evaluate the predictive value of PET/CT for disease upgrading. Approximately 120 participants will be enrolled at Mount Sinai Hospital over 12 months. Study participation will involve one imaging visit, one confirmatory biopsy, and follow-up through review of clinical results. There is minimal risk to participants beyond standard diagnostic procedures. The study is funded jointly by the Icahn School of Medicine at Mount Sinai and Blue Earth Diagnostics, which provides the imaging agent flotufolastat F18 and technical support.

Prostate ART is a two phase study looking at using adaptive radiotherapy to help reduce toxicity for prostate cancer patients. Adaptive radiotherapy is a new technology that provides the ability to account for daily changes in anatomy. Adaptive radiotherapy also provides a foundation for which radiotherapy margins might be safely reduced. Phase 1 of this study is looking to see if a radiation therapist centred adaptive workflow can be implemented. If phase 1 of this study is safe and feasible, the study will proceed to phase 2. Part 2 of the study looks at using adaptive technology to reduce radiation treatment margins. The primary aim of this study is to see whether margin reduced treatment using adaptive radiotherapy can reduce side effects for prostate cancer patients.

Prostate cancer is the most common cancer among men in the United States. Many men with prostate cancer are treated with hormone therapy, also called androgen deprivation therapy (ADT). While this treatment is effective, it often causes bothersome side effects such as hot flashes, poor sleep, fatigue, and other physical and emotional symptoms. There is currently no standard treatment to help manage these side effects in men. Acupuncture is a non-drug treatment that has been shown to help reduce hot flashes and related symptoms in women receiving hormone therapy for breast cancer. However, much less is known about whether acupuncture is helpful for men receiving hormone therapy for prostate cancer. This study will test whether an acupuncture program, combined with usual lifestyle education, is feasible and acceptable for men undergoing ADT. The study will also explore whether acupuncture may help reduce hot flashes and improve related symptoms. A total of 24 men with prostate cancer receiving ADT will be randomly assigned to one of two groups: one group will begin acupuncture right away, and the other group will begin acupuncture after a delay, with regular check-ins during the waiting period. All participants will receive standard lifestyle education. Participants will be followed for about five months and will be asked to complete daily hot flash diaries, questionnaires about their symptoms and quality of life, and wear a Fitbit to track sleep. The results of this pilot study will help determine whether a larger study should be conducted to better understand the role of acupuncture in managing hormone therapy side effects in men with prostate cancer.

Lymphedema of the extremities is common after lymph node surgery in treating several forms of cancer, e.g., breast cancer. However, very little is known of the occurrence of lymphedema of the lower extremities after urologic surgery with lymph node dissection. This project aims to describe the frequency and grade of lymphedema arising after urologic surgery, using the Lymphedema Quality of Life Questionnaire (LymQOL), Delfin MoistureMeter D, and lower limb volume measurements.

The Prostate Active Surveillance Study (PASS) is a research study for men who have chosen active surveillance as a management plan for their prostate cancer. Active surveillance is defined as close monitoring of prostate cancer with the offer of treatment if there are changes in test results. This study seeks to discover markers that will identify cancers that are more aggressive from those tumors that grow slowly.

This study is testing the way that approved androgen deprivation therapy treatments, Leuprolide and Relugolix, for prostate cancer affect quality of life, blood levels, cholesterol, and blood sugar. The drugs are already standard treatment for people with prostate cancer, and the drugs will be used as described in their label. The names of the study drugs involved in this study are: * Leuprolide (type of ADT) * Relugolix (type of ADT)
