Active clinical trials for "Prostatic Neoplasms"

This study is designed to test the hypothesis that using Sipuleucel-T (Provenge) in combination with new hormonal agents (NHA) (abiraterone, enzalutamide, apalutamide) for the treatment of participants with asymptomatic metastatic castration resistant prostate cancer (mCRPC) and no visceral metastases would enhance the activation of antigen presenting cells (APC) by sipuleucel-T.

The aim of this prospective phase II study is to evaluate the toxicity of salvage partial (focal) prostate brachytherapy in patients after prior radiotherapy (standard teleradiotherapy with / without brachytherapy, hypofractionated, self-reactive HDR / LDR brachytherapy) with local recurrence on the part of the prostate gland.

This study is conducted to investigate the pharmacokinetic and safety profiles of TQB3720 in patients with metastatic castration-resistant prostate cancer.

A randomized phase III trial to study the effect of adding lymph node irradiation in patients with poor prostate-specific antigen (PSA) response during salvage radiotherapy for biochemical recurrence (0.15 ≤ PSA <0.70 ng/ml) after prostatectomy.

Background: The ability to treat early prostate cancer is still limited. Thermal ablation methods are being tested for focal prostate cancer therapy. Researchers want to improve on these methods. Objective: To understand if Transurethral UltraSound Ablation (TULSA) in combination with MRI guidance is useful to treat localized prostate cancer. Eligibility: English-speaking adults ages 18 and older with localized prostate cancer that can be seen on MRI and can be treated by thermal ablation. Design: Participants will be screened with the following: Medical history Physical exam Digital rectal exam Blood and urine tests Electrocardiogram Tumor biopsy Questionnaire to assess urinary tract symptoms MRI of the pelvis. The MRI scanner is a long, narrow tube. Participants will lie on a bed that moves in and out of the scanner. Participants may also be screened with the following: Echocardiogram Chest x-ray Bone scan Urodynamic studies to see how well the bladder, sphincters, and urethra hold and release urine MRI of the brain Transrectal ultrasound Computer tomography (CT) scan of the chest, abdomen, and pelvis. A CT scan is a series of x-ray images taken of parts of the body. Some screening tests will be repeated during the study. Participants will have the TULSA procedure. They will have an MRI for guidance. A small ultrasound applicator will be placed into their urethra. It uses heat to destroy the cancer areas in the prostate. It is controlled by a robotic arm. A cooling catheter will be placed into their rectum. Participants will use a urethral catheter for 1-7 days. Participants will have follow-up visits at 3, 6, 12, 18, 24, and 36 months.

The purpose of this study is to assess the safety and effectiveness of radiation therapy with hormone therapy (ADT) and chemotherapy as an investigational study treatment for prostate cancer. This is a phase 2 study to deliver focal radiation with pulsed systemic therapy of Abiraterone, ADT and Lynparza (olaparib) in men with castration sensitive oligometastatic prostate cancer.

Favorable-risk prostate cancer represent a large proportion of patients diagnosed with prostate cancer and image guided radiation therapy (IGRT) is commonly used to treat these patients using protracted courses of up to 39 treatments over 8 weeks. Stereotactic ablative body radiotherapy (SABR) protocols hold the promise of more convenience, less side effects, less cost and improved system capacity without sacrificing excellent cancer control rates. By the same token, prostate high-dose rate (HDR) brachytherapy boost has been shown to be superior to standard external beam radiation. While two HDR fractions appear to optimize patient convenience and outcomes while minimizing costs, we wanted to determine the tolerability of combining one MR-guided HDR treatment with one SABR treatment to further reduce HDR resource use while maintaining favourable treatment outcomes.

Phase 1, first-in-human, open label study of CAR macrophages in HER2 overexpressing solid tumors.

The aim of this study is to test the safety and feasibility of SBRT without ADT in oligometastatic prostate cancer in patients for whom the standard treatment is ADT, and to further explore how long only radiotherapy for oligometastases can prolong biochemical progression-free survival (bPFS). In this study, men with oligometastatic prostate cancer lesions will be randomized (1:1) to ADT versus SBRT. Within 6 weeks of the oligometastases diagnosis, ADT or SBRT (30-50Gy with 3-5 fractions) will be administered.

The purpose of this study is to determine what effects (good and bad) cabozantinib has in treatment of patients with metastatic castrate resistant prostate cancer (mCRPC). The hypothesis for this trial is that cabozantinib has anti-tumor activity in a molecularly-selected group of patients with CRPC.
