Active clinical trials for "Prostatic Neoplasms, Castration-Resistant"

This study is a Japanese post-marketing surveillance (PMS) which is required by the regulatory authorities. General objective of PMS is to confirm the clinical usefulness, especially the safety profile of a drug under the routine clinical practice.

The primary objective was to confirm the effect of tasquinimod in delaying disease progression or death as compared with placebo in chemo-naïve patients with metastatic castrate-resistant prostate cancer (mCRPC). Secondary objectives included further evaluation of the safety profile of tasquinimod, comparison of clinical benefits (such as overall survival and symptoms) of tasquinimod with placebo, to evaluate the quality of life impact and to determine the pharmacokinetics of tasquinimod.

To demonstrate the efficacy of VERU-111 (Sabizabulin) in the treatment of metastatic castration-resistant prostate cancer in patients who have failed prior treatment with at least one androgen receptor targeting agent as measured by radiographic progression-free survival.

Researchers in this study want to compare the effects of drug darolutamide and drug enzalutamide on physical function, including balance and daily activity, in patients with castration-resistant prostate cancer (CRPC). Both darolutamide and enzalutamide are approved AR inhibitors used for the treatment of patients with CRPC. AR inhibitor is a substance that keeps androgens (male sex hormones) from binding to proteins called androgen receptors, which are found in normal prostate cells, some prostate cancer cells, and in some other cells. Preventing this binding blocks the effects of these hormones in the body and therefore keeps prostate cancer cells from growing. Patients participating this study will receive either darolutamide or enzalutamide tablets. To evaluate the physical function, patients will be asked to make some movements like rising from a chair, walking three meters, etc. Additionally, researchers also want to find out the survival of patients and if patients have fatigue (feeling tired), cognitive (learning and thinking) problems, or other medical problems during the trial. Brand name of darolutamide is Nubeqa; brand name of enzalutamide is Xtandi.

A study evaluating the safety, preliminary efficacy and pharmacokinetics of ipatasertib in combination with atezolizumab and docetaxel in participants with mCRPC previously treated with second-generation AR (Androgen Receptor)-targeted therapy. The study consists of two parts: [1] Part A: Safety run-in cohort of approximately 12 participants; [2] Part B: Expansion cohort of approximately 38 participants. All participants in this study will continue to be treated until progression of disease, loss of clinical benefit, unacceptable toxicity or withdrawal of consent.

This Phase III, multicenter, randomized, open-label study will evaluate the safety and efficacy of atezolizumab (anti-programmed death-ligand 1 [anti-PD-L1] antibody) in combination with enzalutamide compared with enzalutamide alone in participants with mCRPC after failure of an androgen synthesis inhibitor (e.g., abiraterone) and failure of, ineligibility for, or refusal of a taxane regimen. Participants will be randomized to one of the two treatment arms (atezolizumab in combination with enzalutamide, and enzalutamide alone) in a 1:1 ratio (experimental to control arm) in global randomized phase. Participants will receive treatment until investigator-assessed confirmed radiographic disease progression per Prostate Cancer Working Group 3 (PCWG3) criteria or unacceptable toxicity.

The overall aim of the trial is to investigate the safety and anti-tumour activity of an experimental drug BI 836845 taken together with the prostate cancer drug, enzalutamide, compared to enzalutamide given alone, in castrate resistant prostate cancer (CRPC) patients that have previously been treated and failed on docetaxel and abiraterone treatments. Initially, a tolerability and safety phase (phase Ib escalation) will be performed to confirm the maximum tolerated dose (MTD), or recommended doses of both BI 836845 and enzalutamide that can be taken together. Once the MTD, or recommended phase II dose, have been determined an expansion cohort will also be explored (phase Ib expansion) in CRPC patients already taking enzalutamide and have a rise in prostate serum antigen (PSA) levels. Patients may not have received prior docetaxel or abiraterone. Patients in this cohort will receive the MTD, or recommended phase II dose, of BI 836845 and enzalutamide determined in the phase Ib escalation phase. The randomised trial (phase II) will be an open label, parallel group study design in a 1:1 ratio to which patients will receive either BI 836845 plus enzalutamide (Arm A) at the MTD/recommended doses, or enzalutamide alone (Arm B). In all parts of the trial safety, anti-tumour activity will be assessed, in addition to circulating tumour cells (CTC), prostate serum antigen (PSA) response and progression, and determination of Overall Survival (OS).

Through gene sequencing of the patient's tissue, to figure out the genomic characteristics of patients with advanced disease and guide the treatment of patients

This is a multicenter phase 2 open label study of pembrolizumab in patients with metastatic castrate resistant prostate cancer (mCRPC) with or without DNA damage repair defects.

The purpose of this study is to evaluate the safety and tolerability of JNJ-56021927 in Japanese participants with metastatic castration-resistant prostate cancer (mCRPC- prostate cancer that is resistant to medical [for example. hormonal] or surgical treatments).
