Active clinical trials for "Prostatic Neoplasms"

This study is an open-label, randomized, expanded/phase II study in subjects with metastatic castrate resistant prostate cancer (mCRPC) who progressed after either abiraterone or enzalutamide. The objective of the study is to evaluate the safety and tolerability of proxalutamide and determine the RP2D for Ph III and/or other confirming studies. Subjects will be randomized into the 2 treatment arms.

A randomized phase II clinical trial (RADIOSA trial: Radioablation with or without Androgen DeprIvation therapy in metachronous prostate cancer OligometaStAsis). The aim is to compare time to progression between the two study arms: SBRT only or SBRT and hormonotherapy (ADT). The primary objective is to compare the progression-free survival (PFS) defined as the absence of new metastatic lesions (local, regional or distant) between the two arms. The secondary endpoints include the comparison of overall survival (OS), biochemical progression-free survival (BPFS), ADT-free survival, local control, treatment-induced acute and late toxicity, time to castration-resistant disease and QoL between the two arms; the development of a dedicated biobanking (collection of plasma and serum) for further biological investigation of predictive/diagnostic factors for personalized treatment; the preliminary evaluation of prognostic biomarkers; the correlation between imaging-derived parameters and treatment outcome.

Men diagnosed with significant cancer confined to the prostate currently undergo radical therapy directed to the whole prostate (radiotherapy or prostatectomy). These provide good cancer control but can cause significant side effects. Focal Therapy involves targeting the cancer alone, whilst leaving healthy prostate gland alone. Case series have shown similar cancer control over 5 years with a much better side effect profile. However, there have been no randomised control trials (RCTs) comparing the success in cancer control and the quality of life in patients that undergo radical therapy vs those that undergo focal therapy. Further, there is a need to assess the use of additional therapies that may improve the cancer control outcomes following focal therapy. By having a trials platform with two RCTs (CHRONOS-A and CHRONOS-B) that reflect best patient and physician preferences/ equipoise, the investigators aim to answer these questions. To improve acceptability, recruitment and compliance, the investigators have an embedded study aimed at reviewing clinician and patient perspectives and trial acceptability. CHRONOS-A will compare radical therapy to focal therapy, whilst CHRONOS-B will compare focal therapy alone to focal therapy with various therapies targeting the testosterone pathway that can shrink the cancer before it is treated. The investigators think this might improve outcomes further for men that definitely want focal therapy.

Stereotactic Body Radiation Therapy(SBRT) for spinal metastases has been proved a good results in pain relieve and local control, However,the longterm of efficacy and safety of this regimen is unclear.The purpose of the study is to evaluate the longterm outcome of this therapeutic regimen in selective patients who will be survival more than 2 years.

The purpose of this research study is to learn more about the outcomes and early and late side effects of treating early stage prostate cancer with high dose rate brachytherapy.

It is estimated that one-third of the more than 7 million deaths from cancer worldwide are attributable to potentially modifiable risk factors, with 374,000 deaths preventable through diet modification alone. Diet supplementation for the prevention or treatment of cancer is attractive, as implementation is relatively easy, even in populations with reduced incomes and resources. Grape extracts or active components isolated from grapes have received attention as chemopreventive or therapeutic agents based upon their anti-proliferative, anti-inflammatory, and anti-oxidant properties. Evidence from preclinical trials also suggests that muscadine grape products may decrease systemic inflammation. This study builds upon promising preclinical and clinical evidence to determine if the addition muscadine grape extract (MGE) to androgen deprivation therapy (ADT) improves symptoms in men with prostate cancer.

PERSEUS1 is an open-label, single arm, phase II trial evaluating the efficacy of Pembrolizumab in metastatic castration resistant prostate cancer (mCRPC) patients (Part A) with a biomarker enrichment stage (Part B) if efficacy is shown in part A.

This study will investigate the safety and efficacy of Sacituzumab Govitecan in patients with metastatic castration-resistant prostate cancer progressing on second generation AR-directed therapy (e.g., enzalutamide, darolutamide, apalutamide and/or abiraterone).

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.

The objective of this study is to determine the maximum safe dose of Ra-223 in combination with fractionated (split doses) docetaxel when given to subjects and to determine the best administering dose. The study will look at side effects that may happen while taking the combination treatment. A total of approximately 18 subjects will take part in the dose escalation part of the study and an additional 25 subjects will participate in the expansion cohort. This study will be conducted across four centers in the United States.
