Active clinical trials for "Prostatic Neoplasms"

The investigators have used national VHA data to demonstrate real-world efficacy of abiraterone and enzalutamide in Veterans with mCRPC. In the real-world that is the VHA, the investigators have successfully estimated g values that accurately predict OS and the use of this metric in other settings should now be explored. In the egalitarian system that is the VHA the treatment of prostate cancer is excellent, uniform across the US and indifferent to race. The choices made are clearly personalized, given not all men received all therapies and that younger Veterans were treated more aggressively. But with survivals that rival those in registration trials that enroll optimally fit individuals usually not encumbered by the co-morbidities that afflict many Veterans, the outcomes are testimony to the fact that for this common malady of older Veterans with whom VA physicians have broad experience the care administered is unsurpassed. Importantly this care at least as regards Veterans with mCRPC demonstrates that given equal access to health care, African Americans with prostate cancer fared as well if not better than Caucasians and importantly had better outcomes with abiraterone, an observation needing further exploration as these therapies move up front.

This project proposes to understand and improve Veterans' decision-making in precision oncology (germline testing, somatic tumor testing, and targeted therapy) for advanced prostate cancer. As precision oncology expands, a comprehensive strategy to support patient informed decision- making (IDM) has not been developed.

The purpose of this study is to evaluate a technical feasibility of MR-guided SBRT fraction dose adaptation for low-risk, intermediate-risk and low-volume metastatic prostate cancer. .

This observational study was designed to evaluate progression free survival after PSMA-PET/CT based salvage approach for patients affected by biochemical relapse after radical prostatectomy.

The goal of this observational study is to learn about the safety and efficacy of two-step radical prostatectomy in the treatment of low- to intermediate-risk prostate cancer patient with enlarged prostate and severe benign prostatic hyperplasia. The main question it aims to answer are: 1. Whether two-step prostatectomy is safe enough to decrease the surgical difficulty of these patients? 2. Whether the oncologic control is promising?

Proposed immunotherapy with an extended course of Sipuleucel-T treatment may induce a more robust immune response and improve the anti-cancer efficacy of Sipuleucel-T in patients with metastatic Castration-Resistant Prostate Cancer (mCRPC).

This is a study of the tolerability and safety of neoadjuvant dapagliflozin for patients with high-risk or very high risk prostatic adenocarcinoma prior to radical prostatectomy. The primary hypothesis is that four weeks of daily dapagliflozin prior to surgery is well-tolerated and safe to use in this patient population.

The RO-PIP trial aims to determine the feasibility of recruitment to a trial randomising patients to salvage ultra-hypofractionated external beam radiotherapy or high dose rate brachytherapy and provide prospective data on patient recorded toxicity outcomes that will inform a future phase III trial.

This single arm observational pilot study aims to determine the longitudinal effects of androgen receptor signaling inhibitors (ARSI) in men with advanced prostate cancer. The primary outcome for this trial is physical function, which will be evaluated at baseline, 12 and 24 weeks. Secondary outcomes including body composition, muscle function, balance, arterial stiffness and patient reported outcomes.

The purpose of this study is to assess the effect of the addition of metformin to abiraterone on survival in patients with metastatic castration-resistant prostate cancer (mCRPC). The half the patients will receive metformin in combination with androgen deprivation therapy (ADT) and abiraterone, and the other half will receive ADT and abiraterone only.
