Active clinical trials for "Prostatic Neoplasms"

This is a phase I, clinical research study of EPI-7386, an investigational drug being studied as a treatment for patients with prostate cancer. All patients in the study will receive EPI-7386. Since this is the first study of EPI-7386 in humans, there is no information about how it affects people or what dose should be used. Therefore, the main purpose of this study is to assess the safety (side effects) of EPI-7386 and to find a dose that can be given without unacceptable side effects. There are other important things that will be evaluated during the study: How the amount of EPI-7386 in the blood changes over time. The effect of EPI-7386 on prostate cancer. The effect of EPI-7386 on certain substances in the body. The possibility that EPI-7386 can interact with other drugs. The study will be conducted in 2 parts: Part A: To evaluate the safety and tolerability of EPI-7386 as a single agent via 2 Phases: Phase 1a: Dose Escalation (mCRPC) Phase 1b: Dose Expansion (mCRPC) Part B: To evaluate 2 parallel enrolling cohorts (Cohort 1 and Cohort 2) of EPI-7386 in combination of apalutamide acetate + prednisone (AAP) or apalutamide (APA): Cohort 1: Combination with AAP in mHSPC or mCRPC patients Cohort 2: Will evaluate the anti-tumor activity of EPI-7386 for a limited window of time (12 weeks EPI-7386 monotherapy prior to the start of combination therapy with APA) in nmCRPC patients unperturbed by previous 2nd generation anti-androgen therapies or chemotheraphy.

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 study is trying to find out if the combination of Androgen deprivation therapy (ADT), MRI guided high dose radiation (HDR) brachytherapy treatment (internal radiation implant procedure) and external beam radiation therapy (EBRT) treatments lead to less side effects. This study is also looking at patient outcomes, quality of life, and overall survival for patients receiving this treatment.

This phase II trial studies how well white button mushroom supplement works in reducing prostate-specific antigen (PSA) levels in patients with prostate cancer that has come back (recurrent) or has favorable risk and has not undergone any therapy (therapy naive). PSA is a blood marker of prostate growth. White button mushroom supplement may affect PSA level, various parameters of immune system and levels of hormones that may have a role in prostate cancer growth.

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.

The ELASTO-US study is a single center feasibility study to evaluate 3 methods of analyzing real-time ultrasound images acquired during High Intensity Focused Ultrasound (HIFU) treatment in patients with localized prostate cancer. Real-time ultrasound acquisitions will be programmed at specific times and recorded during HIFU treatment. At the end of the treatment, these recordings will be exported in an anonymized way and analyzed according to the 3 different methods. A multiparametric-MRI will be performed in addition to the usual practice within 5 days after the treatment in order to control the area necroticised by the treatment. The mp-MRI will be the reference method against which the results obtained by the 3 methods of ultrasound image analysis will be compared. Techniques capable of providing safe and robust information on the progress of HIFU-generated necrosis would greatly limit the risks of overtreatment that can lead to side effects such as urinary incontinence as well as the risks of under treatment that can lead to cancer recurrence.

HS-10502 is a Poly(ADP-ribose) polymerase 1 (PARP1)-specific selective inhibitor. The purpose if this study is to assess the safety, tolerability, pharmacokinetics (PK), and efficacy of HS-10502 in subjects with homologous recombination repair (HRR) gene mutant or homologous recombination deficiency (HRD) positive advanced solid tumors.

Medico-Economic Randomized Trial comparing Focal HIFU Treatment to Radical Prostatectomy in Patients with Favorable Intermediate Risk Prostate Cancer

Phase 1-2 study, comparing ultra-hypofractionnated (UH) to a moderately hypofractionnated (MH) radiation therapy, with image guided HDR prostate brachytherapy. Using iso-equivalent doses, a non-inferiority analysis will be done in order to prove UH non-inferior to MH, toxicity wise. Acceptability, tolerability, acute and late toxicity will be reported. MRI visible dominant intra-prostatic lesion will be outlines and variability between radiation oncologists and radiologists will be reported. As secondary objective, biochemical and clinical failure free survival will be reported at 5 & 10 years.

The main aim of this study is to assess the effectiveness and safety of the 6-month formulation of triptorelin pamoate in Chinese participants with locally advanced or metastatic cancer of the prostate. Participants will receive 1 injection of triptorelin pamoate 6-month formulation.
