Active clinical trials for "Prostatic Neoplasms"

This study will assess the efficacy and safety of pembrolizumab plus enzalutamide plus ADT versus placebo plus enzalutamide plus ADT in participants with mHSPC. The primary hypothesis is that in participants with mHSPC, the combination of pembrolizumab plus enzalutamide plus ADT is superior to placebo plus enzalutamide plus ADT with respect to 1) radiographic progression-free survival (rPFS) per Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by blinded independent central review (BICR) and 2) overall survival (OS). As of Amendment 4, the study is being stopped for futility. All the prespecified interim analyses after interim analysis 1 (IA1) and final analysis of the study described in the statistical analysis plan (SAP) will not be performed. Safety analysis will be performed at the end of the study; there will be no further analyses for efficacy and electronic patient-reported outcome (ePRO) endpoints collected from participants beyond the IA1 cutoff date. All study participants will stop ongoing treatment with pembrolizumab/placebo. Exceptions may be requested for study participants who, in the assessment of their study physician, are benefitting from the combination of enzalutamide and pembrolizumab, after consulting with the Sponsor. All other study participants should be discontinued from study and be offered standard of care (SOC) treatment as deemed necessary by the Investigator. If enzalutamide as SOC is not accessible off study to the participant, central sourcing may continue. As of Amendment 04, disease progression will no longer be centrally verified, participants will only be assessed locally. As of Amendment 4, Second Course treatment is not an option for participants. There are currently no participants in the Second Course Phase.

Study of NGM120 in subjects with advanced solid tumors and and pancreatic cancer (Part 1 and 2) and metastatic castration resistant prostate cancer (Part 3).

This study is a multinational Phase 3, randomized, double-blind, non-inferiority, efficacy and safety study of oral HC-1119 (80 mg/day) versus enzalutamide (160 mg/day) in asymptomatic or mildly symptomatic patients with progressive metastatic castration-resistant prostate cancer (mCRPC). The following assessment of prostate cancer status will be collected during the course of the trial: soft tissue disease on computed tomography (CT) scan or on magnetic resonance imaging (MRI), bone disease on radionuclide bone scans, FACT-P and EQ-5D, Brief Fatigue Inventory, and PSA. Throughout the study, safety and tolerability will be assessed by the recording of adverse events, monitoring of vital signs and physical examinations, safety laboratory evaluations, and 12-lead electrocardiograms (ECGs). Blood samples for population pharmacokinetics for HC-1119 and enzalutamide and related metabolites will be collected.

Magnetic resonance imaging (MRI) has improved detection of clinically significant prostate cancer (PCa). MRI-guided transurethral ultrasound ablation (MRI-TULSA) system incorporates precise diagnosis and simultaneous ablation of prostate tissue enabling lesion-targeted treatment of PCa. Lesion-based treatment strategy spares surrounding healthy tissues from injury, which may improve the outcome of genitourinary function. This study further investigates the safety and the efficacy of lesion-targeted ablation of MRI-visible biopsy-proven PCa with MRI-TULSA.

The purpose of this study is to assess the efficacy and safety of the combination of pembrolizumab (MK-3475) and enzalutamide in the treatment of men with metastatic castration-resistant prostate cancer (mCRPC) who have not received chemotherapy for mCRPC, are abiraterone-naïve, or are intolerant to or progressed on abiraterone acetate. There are two primary study hypotheses. Hypothesis 1: The combination of pembrolizumab plus enzalutamide is superior to placebo plus enzalutamide with respect to Overall Survival (OS). Hypothesis 2: The combination of pembrolizumab plus enzalutamide is superior to placebo plus enzalutamide with respect to Radiographic Progression-free Survival (rPFS) per Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by blinded independent central review.

The purpose of this first-in-human study is to evaluate safety and tolerability of ODM-209 and find the dose of ODM-209.

Prostate cancer is the most commonly diagnosed cancer among men in Western countries. When the disease recurs as castration-resistant prostate cancer (CRPC) it is associated with a median overall survival of approximately 2 years with significant decrement in quality of life due to additional cancer-specific and treatment-induced morbidity. Palliative agents currently used in the CRPC setting include the 2nd generation hormonal agents abiraterone acetate and enzalutamide but also radium-223, docetaxel and cabazitaxel. Choices for treatment strategies are based on multiple factors such as age, co-morbidity and drug toxicity profile. The side effect profile of enzalutamide is associated with central nervous system (CNS side effects) such as fatigue and depression. The mechanism for these side effects is not yet fully understood, but it was shown in rodent studies that enzalutamide and its active metabolite penetrate into the CNS. This might cause the CNS side effects that were later seen in the phase 1 study where fatigue was found to be a dose-dependent adverse event. After dose reductions the symptoms resolved. This was also found in a retrospective study of Japanese metastatic CRPC (mCRPC) patients (n=345) in which the side effects malaise and nausea decreased remarkably after dose reduction. However, no exposure-response relation was observed in the study of Gibbons et al. Additionally, based on the data of the phase 1 trial of enzalutamide it can be suggested that a minimum trough concentration of 5.0 mg/L could be considered as a target for exposure to enzalutamide. In particular, frail (m)CRPC patients are more prone to develop CNS side effects on enzalutamide. The investigator's hypothesis is that dose reduction to 75% (120mg) can be safely done to treat (m)CRPC in these patients with preserving optimal efficacy and less CNS side effects.

This randomized phase II trial studies how well abiraterone acetate and antiandrogen therapy, with or without cabazitaxel and prednisone, work in treating patients with castration-resistant prostate cancer previously treated with docetaxel that has spread to other parts of the body. Androgens can cause the growth of prostate cancer cells. Hormone therapy using abiraterone acetate and antiandrogen therapy may fight prostate cancer by lowering and/or blocking the use of androgens by the tumor cells. Drugs used in chemotherapy, such as cabazitaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving abiraterone acetate and antiandrogen therapy with or without cabazitaxel and prednisone may help kill more tumor cells.

The primary objective of this study is to demonstrate that ultra-hypofractionation of prostate cancer does not increase urinary toxicity as defined by the EPIC-26 GU domain patient reported outcome.

This phase II trial studies how well docetaxel with carboplatin followed by rucaparib camsylate works in treating patients with metastatic castration resistant prostate cancer (spread outside of prostate and resistant to testosterone suppression) with homologous recombination DNA repair deficiency. Chemotherapy drugs, such as docetaxel and carboplatin, work to stop the growth of cancer cells, by stopping them from dividing or spreading. Rucaparib camsylate may stop the growth of tumor cells with defects in the ability to repair mistakes in DNA by forcing additional errors so that the cancer cells cannot overcome the number of errors and will then die. Giving induction docetaxel and carboplatin followed by maintenance rucaparib camsylate may work better in treating patients with castration resistant prostate cancer.
