Active clinical trials for "Prostatic Neoplasms"

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.

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).

Men with prostate cancer with Gleason Score of 8 or greater or clinical/radiographic evidence of T3 disease will be considered for this trial.

The primary objective is to assess the activity and efficacy of pembrolizumab, a checkpoint inhibitor, in Veterans with metastatic castration-resistant prostate cancer (mCRPC) characterized by either mismatch repair deficiency (dMMR) or biallelic inactivation of CDK12 (CDK12-/-). The secondary objectives involve determining the frequency with which dMMR and CDK12-/- occur in this patient population, as well as the effects of pembrolizumab on various clinical endpoints (time to PSA progression, maximal PSA response, time to initiation of alternative anti-neoplastic therapy, time to radiographic progression, overall survival, and safety and tolerability). Lastly, the study will compare the pre-treatment and at-progression metastatic tumor biopsies to investigate the molecular correlates of resistance and sensitivity to pembrolizumab via RNA-sequencing, exome-sequencing, selected protein analyses, and multiplexed immunofluorescence.

INDICATION: Oligometastatic hormone-sensitive prostate cancer patients. METHODOLOGY: Open label, double arm, randomized 1:1, multicenter phase III study. PRIMARY OBJECTIVE: To assess the efficacy of ablative radiotherapy (SBRT applied to all oligometastases) administered to all gross tumor sites (metastases and prostate if applicable), in oligometastatic hormone-sensitive prostate cancer patients.

This is a multicenter, randomized, open label, phase III study comparing the efficacy and safety of apatulamide combined with concomitant prostate-bed salvage radiotherapy (SRT) and androgen deprivation therapy (ADT) versus concomitant prostate-bed SRT and ADT in high-risk postprostatectomy biochemically relapsed prostate cancer patients.

This study was undertaken to evaluate bone response in metastatic prostate cancer patients treated with Enzalutamide with or without Zoledronic Acid in combination with luteinizing hormone-releasing hormone (LHRH) analogue with the use of Whole Boby (WB) DW-MRI.

To compare the toxicity, rate of local control, biochemical failure rate and quality of life of three different radiotherapy techniques (moderate hypofractionation, stereotactic body radiotherapy (SBRT) and standard radiotherapy plus 2 fractions of SBRT (BOOSTER)

A large proportion of men with prostate cancer are overdiagnosed and overtreated mainly due to PSA testing. Active surveillance (AS) aims to reduce these harms by recommending curative treatment only when and if signs of tumour progression occur. There are however a number of uncertainties in AS, the most important being when to initiate treatment. Therefore, the Scandinavian Prostate Cancer Group (SPCG) are running a large multi-centre randomised control trial (RCT) to test the safety of a standardized active surveillance protocol with specific triggers for repeat biopsies and initiation of curative treatment, compared to the current practice for active surveillance. They are recruiting in multiple sites in Sweden, Denmark and Finland. The primary aim is to reduce overtreatment and subsequent side effects, without increasing the risk of disease progression or prostate cancer mortality. In the UK, there is also no set criteria for when to re-biopsy and/or initiate curative treatment for patients on AS and tends to be at the clinician's discretion. Thus, PCASTT-UK has been established to run as a parallel RCT and add to the findings from SPCG-17.

A prospective, open label phase 2 clinical trial assessing safety, complications and feasibility of radical prostatectomy (RARP) plus local stereotactic body radiotherapy (SBRT) to bone metastases in combination with short-term medical castration to a select population of prostate cancer patients with oligometastatic disease.
