Prostate Cancer clinical trials at University of California Health

This phase I trial studies if positron emission tomography (PET) imaging using 11C-YJH08 can be useful for detecting certain cell receptor expression in tumor cells in patients with prostate cancer that has spread to other parts of the body (metastatic). 11C-YJH08 is a small-molecule radiotracer that binds to receptors on cells (glucocorticoid receptor) so that they show up better on the PET scan. Anti-hormone therapy (including enzalutamide) can cause more glucocorticoid receptors to be produced in tumor cells, which can make the tumor cells resist hormone therapies. If researchers can find a better way to detect whether glucocorticoid receptors are increasing during therapy, it may lead to more successful therapies using glucocorticoid receptor antagonists.

A Multi-Center, Open-Label, Randomized Phase 3 Trial Comparing the Safety and Efficacy of 177Lu-PSMA-I&T versus Hormone Therapy in Patients with Metastatic Castration-Resistant Prostate Cancer.

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.

This is a phase 1, open-label study evaluating the safety, clinical pharmacology and clinical activity of AMG 340, a PSMA x CD3 T-cell engaging bispecific antibody, in subjects with metastatic castrate-resistant prostate cancer (mCRPC) who have received 2 or more prior lines of therapy. The study consists of 2 parts, a monotherapy dose escalation (Arm A) and a monotherapy dose expansion (Arm B). Once the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) is identified in Arm A, Arm B will be initiated to further characterize the safety, tolerability and pharmacokinetic (PK) profile of the MTD/RP2D dose of AMG 340 monotherapy in subjects with mCRPC.

The primary objective is to assess the activity and efficacy of pembrolizumab, a checkpoint inhibitor, in Veterans with metastatic castration-resistant prostate cancer (mCRPC) characterized by either mismatch repair deficiency (dMMR) or biallelic inactivation of CDK12 (CDK12-/-). The secondary objectives involve determining the frequency with which dMMR and CDK12-/- occur in this patient population, as well as the effects of pembrolizumab on various clinical endpoints (time to PSA progression, maximal PSA response, time to initiation of alternative anti-neoplastic therapy, time to radiographic progression, overall survival, and safety and tolerability). Lastly, the study will compare the pre-treatment and at-progression metastatic tumor biopsies to investigate the molecular correlates of resistance and sensitivity to pembrolizumab via RNA-sequencing, exome-sequencing, selected protein analyses, and multiplexed immunofluorescence.

Patients with post-prostatectomy PSA (Prostate Specific Antigen) recurrences with aggressive disease features will receive salvage radiation therapy and standard androgen deprivation therapy (ADT) or enhanced ADT to determine if there is any improvement in progression-free survival when enhanced ADT is used compared to standard ADT.

To evaluate the safety and tolerability of Tarlatamab and will determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D).

An open-label, multicenter, Phase 1b/2 study to identify the recommended Phase 2 dose and assess the efficacy and safety of BXCL701 administered orally, as monotherapy and in combination with PEMBRO, in patients with mCRPC. Patients enrolled in the Phase 2a portion of the study will have either Small Cell Neuroendocrine Prostate Cancer(SCNC)(Cohort A) or adenocarcinoma phenotype (Cohort B), while the Phase 2b randomized portion of the study will enroll only the histologic subtype(s) showing preliminary evidence in Phase 2a. The study will also assess other efficacy parameters, such as rPFS, PSA PFS, OS, and DOR, as well as the safety of the combined treatment. The study will consist of three components.

This phase 2, open-label, dual-center, two-arm randomized controlled trial (RCT) investigates the effects of 16 weeks of structured aerobic training, relative to usual care (print material with physical activity guidance). Prostate genomic signatures represent the functional activity of all genes in the genome and are converted into genomic risk scores which correspond to the probability of a progression event (chance of having more aggressive disease). A structured exercise program may alter the genomic risk score and improve prediction of aggressive disease.

Despite the low androgen receptor (AR) transcriptional activity of treatment-emergent small cell neuroendocrine prostate cancer, there is persistent AR expression observed in the majority of treatment-emergent small-cell neuroendocrine prostate cancer (t-SCNC) biopsies. This indicates that epigenetic dysregulation leads to reprogramming away from an AR-driven transcriptional program. Therefore, continuation of AR blockade in the form of apalutamide may provide additive benefit compared to immune checkpoint blockade alone. The investigators hypothesize that the combination of apalutamide plus cetrelimab will achieve a clinically significant composite response rate with sufficient durability of response in mCRPC patients with evidence of treatment-emergent small cell neuroendocrine prostate cancer

This phase II trial studies the how well apalutamide with or without stereotactic body radiation therapy work in treating participants with castration-resistant prostate cancer. Testosterone can cause the growth of prostate cancer cells. Hormone therapy using apalutamide may fight prostate cancer by blocking the use of testosterone by the tumor cells. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. It is not yet known whether giving apalutamide with or without stereotactic body radiation therapy works better in treating participants with castration-resistant cancer.

The Prostate 8-II study is a randomized controlled trial of testing different combinations of educational and supportive tools related to diet and exercise to evaluate biological, clinical, and quality of life outcomes in men choosing radical prostatectomy as treatment for prostate cancer.

This is a Phase 1b/2 study evaluating FOR46 in combination with enzalutamide in patients with metastatic castration resistant prostate cancer (mCRPC) after prior progression on abiraterone. FOR46 is designed to target and bind to CD46, a transmembrane cellular protein expressed at moderate or high levels in numerous cancer types. The investigators hypothesize that the combination of FOR46 plus enzalutamide will achieve a clinically significant composite response rate with sufficient durability of response in mCRPC patients.

This phase II trial studies the side how well hyperpolarized carbon C 13 pyruvate (HP C-13 pyruvate) magnetic resonance imaging (MRI) works in monitoring patients with prostate cancer on active surveillance who have not received treatment. Diagnostic procedures, such as MRI, may help visualize HP C-13 pyruvate uptake and breakdown in tumor cells.

This clinical trial studies a digital platform, the supportive therapy in androgen deprivation (STAND-T), in achieving equity for men undergoing treatment with androgen deprivation therapy for prostate cancer. STAND-T is a digital platform that provides prostate health information, evidence-based materials and resources. STAND-T may help improve health, address symptoms, and promote equity in men with prostate cancer.

This is a prospective imaging study evaluating the utility of baseline metabolic MR imaging as a diagnostic and response monitoring tool in patients with advanced prostate cancer. Preliminary pre-clinical and clinical data demonstrates the ability of HP C-13 pyruvate/metabolic MR imaging to detect high-grade prostate cancer, including cancer with neuroendocrine differentiation, as well as provide early evidence of metabolic response and resistance following application of systemic therapies for the treatment of advanced prostate cancer patients. In the proposed study, the investigators aim is to extend the initial clinical results and further develop HP C-13 MRI as an imaging modality in advanced prostate cancer.

This is a single-arm hybrid implementation trial of men with metastatic castrate-resistant prostate cancer (mCRPC) involving a patient-administered mobile app for consultation audio recordings.

This phase II trial studies how well atezolizumab works alone or in combination with etrumadenant or tocilizumab in treating men with localized prostate cancer before radical prostatectomy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Androgens can cause the growth of prostate cancer cells. IL-6 is expressed by prostate cancer and within the tumor microenvironment and shown to enhance prostate cancer and disease progression. Treatment with an anti-IL-6 antibody such as tocilizumab may inhibit cancer progression. Giving atezolizumab in combination with etrumadenant or tocilizumab may work better in treating prostate cancer.

Prostate-specific membrane antigen (PSMA) agents have shown promise in detecting and treating prostate cancer. Gallium-68-labeled PSMA-11 (68Ga-PSMA-11) is a radioactive agent that binds to prostate cancer cells and can be imaged using positron emission tomography (PET) scanners that detect radioactivity in the body. This early phase I study will use PET to determine if delivering 68Ga-PSMA-11 directly into the prostatic artery (intra-arterial (IA) administration) results in greater uptake in the prostate than delivering 68Ga-PSMA-11 into a vein in the arm (intravenous (IV) administration).

This pilot clinical trial studies how well magnetic resonance spectroscopic imaging (MRSI) with hyperpolarized carbon C13 pyruvate works in finding prostate cancer that exhibits poorly differentiated or undifferentiated cells (high-grade) and that is restricted to the site of origin, without evidence of spread (localized) in patients undergoing radical prostatectomy. Diagnostic procedures, such as MRSI with hyperpolarized carbon C13 pyruvate, may aid in the diagnosis of prostate cancer and in discriminating high-grade from low-grade prostate cancer and benign adjacent prostate tissue

Reduction of dose to or 'sparing' of neurovascular structures during stereotactic ablative body radiotherapy (SAbR) for localized prostate cancer will improve retention of sexual potency, while retaining excellent oncologic control and other secondary health-related quality of life (HRQOL) endpoints. Primary Objectives: • To compare the decline in patient health-related quality of life (HRQOL) instrument-defined erectile dysfunction following stereotactic ablative body radiotherapy (SAbR) with or without neurovascular sparing Secondary Objectives: - Assess acute (within 3 months of treatment) and chronic (>3 months after treatment) SAbR related GU and GI toxicities, as well as serial impact on HRQOL metrics over time - Assess biochemical progression free survival, local recurrence, distant recurrence, and survival - Evaluate simplified 'practical' secondary HRQOL sexual potency endpoints that can be compared to prior literature. Exploratory Objectives: - Evaluate feasibility of MRI BOLD/TOLD to be integrated as hypoxia monitoring sequences to standard already planned diagnostic and/or treatment planning MRI on the study in five patient pilot. - Evaluate quality of spacer placement and its effect on dose to neurovascular structures - Evaluate rate local recurrence in the area of sparing adjacent to the neurovascular elements by biopsy in those with biochemical progression.

Background: People with prostate cancer usually have their cancer imaged with a CT scan and bone scan. They then have their prostate gland removed. Researchers want to test a scan that might predict if prostate cancer will return after this surgery. Objective: To test if a PET/CT scan before the prostate gland is removed can predict if prostate cancer will return. Also, to test if this approach is better or worse than the usual approach for prostate cancer. Eligibility: Men ages 18 and older with prostate cancer that appears to be contained within the prostate but is at risk of having spread Design: Participants will be screened with: - Medical history - Blood tests - CT and MRI scans: Participants will lie in a machine. The machine will take pictures of the body. - Bone scan Participants will have a radiotracer injected into a vein. They will have a PET/CT scan of their whole body 60 90 minutes later. During the scan, they will lie on their back and stay still. Within 60 days after the scan, participants will have surgery. This will remove the prostate gland and lymph nodes around it. Some tissue will be used for genetic testing. If the PET/CT scan suggests the cancer has spread, participants may need to have another biopsy within 60 days after the scan. After surgery, participants will have follow-up visits for 5 years. They will have 5 visits the first year and 2 the second. Then they will have visits once a year. If participants cancer returns, they will have repeat PET/CT scans.

Evaluate the safety and tolerability of AMG 509 in adult participants and determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D).

This study is a first-in-human, Phase 1, open-label, multicenter study to assess the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and the preliminary efficacy of JANX007 administered as a single agent in adult subjects with metastatic castration-resistant prostate cancer (mCRPC).

This phase II trial investigates how well ZEN-3694, enzalutamide, and pembrolizumab work in treating patients with castration-resistant prostate cancer that has spread to other places in the body (metastatic). ZEN-3694 blocks the expression of the MYC gene to prevent cellular growth in certain types of tumors, including castrate resistant prostate cancer. Enzalutamide has been shown to block testosterone from reaching prostate cancer cells by binding to a receptor on prostate cancer cells, called androgen receptors. This works similar to a lock and key. When enzalutamide (key) inserts into the androgen receptor (lock) testosterone cannot attach to the androgen receptor, which slows the growth of tumor cells and may cause them to shrink. Pembrolizumab is a monoclonal antibody (proteins that can protect the body from foreign organisms, such as bacteria and viruses) designed to block a specific control switch which may be activated by tumor cells to overcome the body's natural immune system defenses. It also enhances the activity of the body's immune cells against tumor cells. The purpose of this study is to find out the effects ZEN-3694, enzalutamide, and pembrolizumab on patients with metastatic castration-resistant prostate cancer who have previously experienced disease progression.

This is an open-label, randomized, Phase 2b study of ZEN003694 in combination with enzalutamide vs. enzalutamide monotherapy in patients with mCRPC who have progressed on prior abiraterone by PCWG3 criteria. Disease must have progressed on only abiraterone by PCWG3 criteria prior to study entry. The patient population will be separated into two cohorts: Cohort A: Patients with poor response to prior abiraterone defined as: - Abiraterone started in hormone-sensitive prostate cancer (HSPC) disease setting: < 12 months duration on abiraterone or failure to achieve PSA nadir of 0.2 ng/mL while taking abiraterone, or; - Abiraterone started in castrate-resistant prostate cancer (CRPC) disease setting: < 6 months duration on abiraterone or failure to achieve PSA50 response while on abiraterone Cohort B: Patients with response to prior abiraterone, defined as: - Abiraterone started in hormone-sensitive prostate cancer (HSPC) disease setting: ≥ 12 months duration on abiraterone and nadir PSA < 0.2 ng/mL, or; - Abiraterone started in castrate-resistant prostate cancer (CRPC) disease setting: ≥ 6 months duration on abiraterone and confirmed PSA50 response

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.
