Prostate cancer clinical trials in San Diego

The researchers hope to learn if specific types of MRI software and techniques can help improve early prostate cancer detection at time of a MRI-guided prostate biopsy.

This phase III trial studies whether adding apalutamide to the usual treatment improves outcome in patients with lymph node positive prostate cancer after surgery. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgens, or male sex hormones, can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may help stop or reduce the growth of prostate cancer cell growth by blocking the attachment of androgen to its receptors on cancer cells, a mechanism similar to stopping the entrance of a key into its lock. Adding apalutamide to the usual hormone therapy and radiation therapy after surgery may stabilize prostate cancer and prevent it from spreading and extend time without disease spreading compared to the usual approach.

This study will assess the safety and tolerability of valemetostat in combination with darolutamide in participants with Metastatic Castration Resistant Prostate Cancer (mCRPC).

This is a three-part study evaluating the safety and efficacy of a PSMA-directed radioantibody (rosopatamab tetraxetan, conjugated to either In-111 or Ac-225). Part 1 will consist of one administration of In-111-rosopatamab tetraxetan to characterize the biodistribution of the radioantibody to target organs and prostate cancer lesions. Participants then will be enrolled into either Part 2 (Dose Optimization) or Part 3 (Dose Escalation and Expansion) depending on their prior treatment history. Participants qualifying for Part 2 will be randomized to receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle (dose administration on Day 1 and Day 15) at either 45 or 60 kBq/Kg. Participants qualifying for Part 3 must have received prior Lu-177-PSMA-radioligand therapy and will receive Ac-225 rosopatamab tetraxetan in a single fractionated cycle at 45, 55, or 60 kBq/Kg. Dose limiting toxicities (DLTs) will be monitored in Part 3 to determine the recommended phase 2 dose (RP2D), and the study may enroll additional participants to be treated with the RP2D dose level. Participants enrolled into any part will attend study visits which will include blood samples, electrocardiogram (ECG), radiographic imaging, and physical examinations along with other assessments.

This phase III trial tests two questions by two separate comparisons of therapies. The first question is whether enhanced therapy (apalutamide in combination with abiraterone + prednisone) added to standard of care (prostate radiation therapy and short term androgen deprivation) is more effective compared to standard of care alone in patients with prostate cancer who experience biochemical recurrence (a rise in the blood level of prostate specific antigen \[PSA\] after surgical removal of the prostate cancer). A second question tests treatment in patients with biochemical recurrence who show prostate cancer spreading outside the pelvis (metastasis) by positron emission tomography (PET) imaging. In these patients, the benefit of adding metastasis-directed radiation to enhanced therapy (apalutamide in combination with abiraterone + prednisone) is tested. Diagnostic procedures, such as PET, may help doctors look for cancer that has spread to the pelvis. Androgens are hormones that may cause the growth of prostate cancer cells. Apalutamide may help fight prostate cancer by blocking the use of androgens by the tumor cells. Metastasis-directed targeted radiation therapy uses high energy rays to kill tumor cells and shrink tumors that have spread. This trial may help doctors determine if using PET results to deliver more tailored treatment (i.e., adding apalutamide, with or without targeted radiation therapy, to standard of care treatment) works better than standard of care treatment alone in patients with biochemical recurrence of prostate cancer.

Phase 2 open-label, single-arm clinical trial evaluating the efficacy and safety of neoadjuvant olaparib + LHRH agonist administered for 6 months prior to radical prostatectomy (RP) in men with unfavorable intermediate-risk or high-risk localized prostate cancer. All patients must have confirmed germline or somatic select HRR alterations. Germline and somatic mutation testing will be performed as part of commercially available CLIA assays and will be validated on a uniform platform centrally all patients retrospectively. Eligible patients will receive treatment with olaparib + LHRH agonist. Following 6 months of therapy, patients will undergo RP with mandatory lymph node dissection. The lymph node dissection template will be at the discretion of the treating urologist. RP specimens will undergo pathology blinded independent central review. Following RP, patients will be followed for testosterone recovery and PSA progression.

This is a phase II non-blinded randomized controlled trial of image-guided, tumor-focused radiotherapy in patients with intermediate- or high-risk prostate cancer planning to undergo definitive radiotherapy with or without systemic therapy. The image-guided, tumor-focused radiotherapy will be compared to standard, whole-prostate treatment. The investigators hypothesize that tumor-focused radiotherapy reduces the radiation dose to organs close to the prostate, possibly leading to decreased acute toxicity to the genitourinary and gastrointestinal organs. The investigators will measure acute and late genitourinary and gastrointestinal toxicity due to radiation and regardless of cause. The investigators will also measure overall survival, metastasis-free survival, and quality of life, as well as biomarkers that may help predict, in the future, who may have a worse toxicity following radiation therapy.

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.

Asymptomatic men without pain due to prostate cancer progressing with metastatic CRPC after treatment with combination or sequential ADT + Abi will be treated on a randomized, open label study to determine if sequential treatment with high dose T and Enza will improve primary and secondary objectives vs. continuous Enza as standard therapy.

This phase III trial compares the effect of adding docetaxel to hormonal therapy and apalutamide versus hormonal therapy and apalutamide alone in treating patients with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Hormone therapy for prostate cancer, also called androgen deprivation therapy (ADT), uses surgery or drugs to lower the levels of male sex hormones in a man's body. This helps slow the growth of prostate cancer. Apalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Giving docetaxel in addition to the usual treatment of hormonal therapy and apalutamide may work better in treating patients with metastatic prostate cancer than the usual treatment alone.

The purpose of this study is to find out whether treatment with pasritamig and docetaxel prolongs radiographic progression free survival (rPFS) (the length of time from start of treatment until disease worsens as determined by scans) when compared to treatment with docetaxel in participants with metastatic castrate-resistant prostate cancer (mCRPC; a cancer of prostate, a male reproductive gland found below the bladder, that grows despite low levels of male hormones).

This phase II trial evaluates whether genetic testing in prostate cancer is helpful in deciding which study treatment patients are assigned. Patient cancer tissue samples are obtained from a previous surgery or biopsy procedure and tested for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) abnormalities or mutations in their cancer. Valemetostat tosylate is in a class of medications called EZH1/EZH2 inhibitors. It blocks proteins called EZH1 and EZH2, which may help slow or stop the spread of tumor cells. 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. Cabazitaxel injection is in a class of medications called microtubule inhibitors. It works by slowing or stopping the growth of tumor cells. Abiraterone acetate blocks tissues from making androgens (male hormones), such as testosterone. This may cause the death of tumor cells that need androgens to grow. It is a type of anti-androgen. Enzalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Lutetium Lu 177 vipivotide tetraxetan is in a class of medications called radiopharmaceuticals. It works by targeting and delivering radiation directly to tumor cells which damages and kills these cells. Assigning patients to targeted treatment based on genetic testing may help shrink or slow the cancer from growing

This is an open label, phase I, multi-center study aiming to assess the safety and tolerability in patients with metastatic castration resistant prostate cancer (mCRPC).

This is a multicenter, multinational trial to evaluate advanced MRI techniques for improved detection of clinically significant prostate cancer (csPCa). The study will enroll 500 participants at 5 clinical centers (100 participants per center). The current standard MRI technique for prostate cancer screening is multiparametric MRI (mpMRI), but two drawbacks include need for intravenous (IV) contrast and dependence on radiologist expertise. The investigators expect that the combination of two other techniques, biparametric MRI (bpMRI) and Restriction Spectrum Imaging restriction score (RSIrs), will help non-expert radiologists achieve similar performance to expert radiologists using bpMRI or mpMRI for detection of csPCa, while avoiding the drawbacks that are present when using mpMRI.

The purpose of this study is to evaluate the overall survival (length of time from the start of study to date of death from any cause) for pasritamig (JNJ-78278343) in combination with best supportive care (BSC) as compared to placebo with BSC in participants with metastatic castration-resistant prostate cancer (mCRPC; a stage of cancer that has spread beyond the prostate gland and is no longer responding to hormone therapies).

This Phase II study aims to evaluate efficacy and safety of the combination of JSB462 (also known as luxdegalutamide) at 100 mg and 300 mg once a day (QD) doses + abiraterone compared with an androgen receptor pathway inhibitor (ARPI, abiraterone or enzalutamide) in participants with metastatic Hormone Sensitive Prostate Cancer (mHSPC) and to select the recommended dose of the combination for phase III. Towards that end, the totality of the efficacy, safety, tolerability and PK data from participants randomized in the study will be evaluated

This is a multicenter, single-arm, two-stage open-label phase 2 study of the combination of cabozantinib + nivolumab in subjects with advanced castration-resistant prostate cancer (CRPC).

The researchers are doing this study to find out whether tarlatamab is an effective treatment for Delta-like Protein 3 (DLL3)-positive prostate cancer that has spread to other parts of your body (metastasized) and has either come back after treatment (relapsed) or not responded to treatment (refractory).

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 will explore whether a combination of the investigational drug PF-06821497 and enzalutamide will work better than taking enzalutamide alone in participants with mCRPC who are ARSi or abiraterone naïve.
