Prostate cancer clinical trials in Seattle

This study is being done to answer the following question: can the chance of prostate cancer growing or spreading be lowered by adding a drug to the usual combination of drugs? This study would like to find out if this approach is better or worse than the usual approach for prostate cancer. The usual approach for patients who are not in a study is hormone treatment with Androgen Deprivation Therapy (ADT) and Androgen-Receptor Pathway Inhibitor (ARPI).

This study investigates ways to detect prostate cancer earlier in people at genetic risk for disease that forms, grows, or spreads quickly (aggressive). Studying samples of blood, urine, and/or tissue in the laboratory may help doctors further understand the genetics of prostate cancer and help identify ways to detect cancer earlier, thereby improving treatment and methods of early detection in the future.

This is a two-part, Phase I/II, open-label, global, multicenter study assessing the safety and efficacy of the combination of tulmimetostat (DZR123) and JSB462 (luxdegalutamide) versus standard of care in participants with progressive metastatic castrate resistant prostate cancer (mCRPC).

The Phase 2 monotherapy portion of this study is currently enrolling and will evaluate the efficacy and safety of PC14586 (INN rezatapopt) in participants with locally advanced or metastatic solid tumors harboring a TP53 Y220C mutation. The Phase 1 portion of the study will assess the safety, tolerability and preliminary efficacy of multiple dose levels of rezatapopt as monotherapy and in Phase 1b in combination with pembrolizumab.

The goal of this clinical trial is to measure the toxicity and effectiveness of the following treatments for cFIR/cgUIR prostate cancer patients. Stereotactic body radiotherapy (SBRT) alone or Stereotactic body radiotherapy (SBRT) combined with Ultrashort GNRH Antagonist called Relugolix (an oral drug). Treatments will be randomly assigned to study patients. The main questions it aims to answer are the following: 1. Whether the proportion of men who undergo SUGAR have superior rate of attaining PSA nadir of \<= 0.2 compared to SBRT alone, and 2. Whether SUGAR is superior to historical rates of minimal clinically important decline (MCID) in sexual and hormonal function at 6 months for patients undergoing 6 months of androgen deprivation therapy (ADT) Men aged 18+ with cFIR/cgUIR will be enrolled. Specifically, patients must meet one of the following 2 criteria: 1) Gleason score must be Gleason 3+4 with a PSA \< 20 ng/mL, or 2) Gleason 6 (3+3) and PSA \> 10 ng/mL and \< 20 ng mL.

This is a first-in-human Phase 1a/1b multicenter, open-label oncology study designed to evaluate the safety and anti-cancer activity of NX-1607 in patients with advanced malignancies.

This phase III trial studies how well standard systemic therapy with or without definitive treatment (prostate removal surgery or radiation therapy) works in treating participants with prostate cancer that has spread to other places in the body. Addition of prostate removal surgery or radiation therapy to standard systemic therapy for prostate cancer may lower the chance of the cancer growing or spreading.

This study collects and studies tissue and blood samples from patients with prostate or bladder/urothelial cancer that has recurred (come back) at or near the same place as the original (primary) tumor or has spread to other parts of the body. Studying samples of blood and tissue samples from patients with prostate or bladder/urothelial cancer in the laboratory may help doctors learn more about new biomarkers, potential drug targets, and resistance developing in response to treatment. It may also help doctors find better ways to treat the cancer.

The purpose of this study is to evaluate the safety, tolerability, dosimetry and preliminary efficacy of \[225Ac\]Ac-ETN029 and the safety and imaging properties of \[111In\]In-ETN029 in patients aged ≥ 18 years with locally advanced or metastatic DLL3 positive cancers.

The purpose of this substudy is to assess the efficacy and safety of ifinatamab deruxtecan (I-DXd), given alone or with other treatments in participants with metastatic castration-resistant prostate cancer (mCRPC). The goals of this study are to learn about: * The safety of the study treatment and if people tolerate it. * A safe dose level of I-DXd that can be used with other treatments. * Participant levels of prostate specific antigen (PSA) during treatment.

This is a first-in-human, Phase 1/2, open-label, dose escalation, dose expansion and combination study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of Peluntamig (PT217) as a monotherapy and in combination with chemotherapy.

Phase 1 dose escalation and expansion study of CLSP-1025, a first-in-class HLA-A\*02:01 specific T cell engager (TCE) targeting solid tumors that harbor the p53 R175H mutation.

The objective of this study is to see if providing an appropriate therapy based on the genomic testing of prostate tumour tissue will result in an improved clinical response. Each participant will be treated with 8 weeks of a luteinizing hormone-releasing hormone agonist (LHRHa) plus apalutamide (APA) while genome sequence characterization is being done. Participants with biopsy specimens deemed unevaluable for genomic testing will remain on LHRHa plus APA for an additional 16 weeks. Participants with evaluable tissue will be assigned to one of the open-label sub-studies on the basis of genomic profiling results. Within each group, they will be randomized to a specific treatment arm either LHRHa plus APA alone or adding abiraterone acetate and prednisone, docetaxel or niraparib. The study will evaluate the response rate and outcomes after radical prostatectomy in each arm of the trial.

This is a two-part, open-label, multicenter, dose escalation and dose expansion study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PDx), and anti- tumor activity of ETX-19477, a novel reversible small molecule inhibitor of PARG.

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.

The investigators have used national VHA data to demonstrate real-world efficacy of abiraterone and enzalutamide in Veterans with mCRPC. In the real-world that is the VHA, the investigators have successfully estimated g values that accurately predict OS and the use of this metric in other settings should now be explored. In the egalitarian system that is the VHA the treatment of prostate cancer is excellent and uniform across the US. The choices made are clearly personalized, given not all men received all therapies and that younger Veterans were treated more aggressively. But with survivals that rival those in registration trials that enroll optimally fit individuals usually not encumbered by the co-morbidities that afflict many Veterans, the outcomes are testimony to the fact that for this common malady of older Veterans with whom VA physicians have broad experience the care administered is unsurpassed. Importantly this care at least as regards Veterans with mCRPC demonstrates that given equal access to health care, all men with prostate cancer fare comparably well. As our sophistication in categorizing cancers molecularly has increased this study will look to better examine any emerging differences across study participants.

Background: Prostate cancer is the most common cancer and the second leading cause of death in males in the United States. Researchers want to find additional gene mutations that may increase a man s risk for prostate cancer and may affect how aggressive the disease is. Objective: To look at gene mutations in men with prostate cancer as well as the course of their disease to better understand how gene mutations relate to the way the cancer progresses and responds to treatment. Eligibility: Adult males 18 and older with prostate cancer who have at least one of the gene mutations researchers want to study and/or have been treated for their cancer and have had complete elimination of their cancer or stable disease for a long time. Design: Participants will be screened with a review of their medical records. Their gene test results will be reviewed, if available. They will be asked questions over the phone or in person. Participants do not need to visit the NIH for this study. But if they visit NIH for another study, their data and test results will be collected. They may give blood and urine samples. They may give leftover tumor samples. These samples will be used to study their genes. Participants who do not come to NIH on regular basis will be contacted every 6 months by phone or e-mail. They will be asked questions about their health. Data from their medical records will be collected. Participants will have testosterone and prostate-specific antigen (PSA) tests. Participants may be invited to NIH to give blood samples for research. Participants on this study will be followed for life.

The purpose of this study is to learn about the safety and effects of the study medicine (called Mevrometostat) for the possible treatment of Relapsed/ Refractory Small Cell Lung Cancer (SCLC), Castration Resistant Prostate Cancer (CRPC) and Follicular Lymphoma (FL). The study consists of 3 parts; Part 1 and 2 enrolled participants with SCLC, metastatic CRPC, and FL are closed for enrollment. Part 3, which is open for enrollment is seeking men who: * have Castration Resistant Prostate Cancer (CRPC) and * have previously received treatment for CRPC and have progressed from the last treatment All participants in Part 3 of this study will receive mevrometostat and/ or enzalutamide. Part 3 consists of 2 sub studies each has an assessment phase and a maintenance phase. The Part 3 DDI substudy consist of 2 cohorts, Cohort 1 (monotherapy cohort) and Cohort 2 (Combination cohort). In the assessment phase: * participants in the BE substudy will take 3 single doses of mevrometostat by mouth over 3 periods. * participants in the DDI substudy Cohort 1 (monotherapy cohort) will take mevrometostat 2 times a day and/or itraconazole 1 time a day based on a present schedule. * participants in the DDI substudy Cohort 2 (combination cohort) will take mevrometostat 2 times a day, enzalutamide 1 time a day, and/or itraconazole 1 time a day based on a present schedule. After completion of the assessment phase, participants will enter the maintenance phase where they will receive mevrometostat 2 times a day and enzalutamide 1 time a day by mouth until their cancer is no longer responding. The study will look at the experiences of participanrs receiving the study medicine. This will help see if the study medicine is safe and effective.

This phase II trial tests how well carboplatin before surgery works in treating patients with high-risk prostate cancer and an inherited BRCA1 or BRCA2 gene mutation. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping, or slowing the growth of tumor cells. Giving carboplatin before surgery may shrink tumors in patients with high-risk prostate cancer with BRCA1 and BRCA2 gene mutations.

This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period of time. This trial is evaluating if shorter duration radiation prevents cancer from coming back as well as the usual radiation treatment.
