Active clinical trials for "Prostatic Neoplasms"

Accelerated Hypofractionation Radiotherapy for prostate cancer of 36.25 Gy delivered in 5 fractions will not be inferior to the standard treatment of 70.2 Gy given in 26 fractions with respect to two-year failure defined as a positive biopsy two years post treatment completion or earlier evidence of biochemical or clinical failure.

The percentage of malignant prostate tumors detected very early is constantly increasing and the number of well differentiated tumors, with small volume and low risk of progression increases. When a tumor of this type is identified, radical prostatectomy remains the reference treatment, but this treatment is not without side effects. Active surveillance is a strategy which aims at detecting an early development of the cancerous disease in order to propose curative treatment in a timely manner and thus improve specific survival. Patients are therefore re-evaluated each year by rectal examination, PSA (Prostate-Specific Antigen) assay. Active surveillance remains difficult to manage psychologically for both the patient and the practitioner, because of the lack of treatment on the one hand and a rate of non-curable cancers close to 50% when signs of progression trigger a radical treatment. The aim of the focal treatment HIFU (High Intensity Focused Ultrasound) is to destroy the cancer without causing side effects in contrast to radical treatments. It is in this sense that it is positioned both as an alternative to radical surgery and as an alternative to active surveillance.

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 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.

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.

This is a 2x2 factorial randomized, multicenter, international, open phase III trial. The primary objective is to evaluate the benefit of acetylsalicylic acid and atorvastatin on overall survival (OS) (main endpoint) for patients with castrate-resistant prostate cancer starting first line treatment for CRPC

This is a prospective study to determine if the use of curcumin randomized against placebo will reduce cancer progression in patients with prostate cancer undergoing active surveillance.

This is a randomized control trial testing the effect of walnut supplementation on prostate cancer progression in 50 men with biopsy confirmed prostate cancer and planning to undergo RP. Patients consented to the study will be randomly assigned to either continue their usual diets (control arm) or to the walnut arm for 4-10 weeks depending on the window between their consent date and the date for RP.

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.
