Active clinical trials for "Prostatic Neoplasms"

The purpose of this study is to: a) establish the recommended phase 2 dose (RP2D) and to evaluate the antitumor activity and safety of niraparib combination therapies (Combinations 1 and 2) and b) to determine the relative bioavailability of niraparib and abiraterone acetate (AA) in combination (Combination 3) in participants with metastatic castration-resistant prostate cancer (mCRPC).

This study offers focal therapy for prostate cancer by using an intra-urethral radiotransponder temporarily placed during radiotherapy. The study aims to improve the risk-benefit ratio of therapy for early prostate cancer and potentially lessen symptom burden over time.

The purpose of this study is to evaluate the safety and tolerability of enzalutamide in Indian patients with progressive mCRPC previously treated with docetaxel-based chemotherapy. This study will also evaluate the effect of enzalutamide on prostate-specific antigen (PSA).

Conventional treatment options for localized prostate cancer include prostatectomy, radiotherapy and active surveillance. However, prostatectomy and radiotherapy carry certain degree of morbidity, including the risks of urinary incontinence, erectile dysfunction and injury to the surrounding organs like rectum and bladder. Active surveillance carries the risk of disease progression and psychological distress to the patients. Focal therapy employs the concept of only destroying the target lesion without treating other benign areas, resulting in disease cure in majority of cases with less treatment morbidity. Microwave treatment to the prostate has been performed since more than 20 years ago for benign prostatic hyperplasia and is approved by FDA in United States. It exerts its effect through thermal destruction of prostate tissue. Targeted treatment of localized prostate cancer using microwave needle ablation guided by MRI and Ultrasound imaging has been performed recently and was shown to be safe and effective. Our study aims to assess the effectiveness of this focal therapy in treating localized prostate cancer.

To determine the efficacy of using MRI/US fusion imaging technology to direct focal ablation of prostate tissue using nanoparticle-directed laser irradiation.

This phase II trial studies how well radiation therapy with or without apalutamide works in treating patients with stage III-IV prostate cancer. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgen can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may lessen the amount of androgen made by the body. Giving radiation therapy and apalutamide may work better at treating prostate cancer than radiation alone.

This randomized, controlled, single center clinical trial aims to evaluate the efficacy and safety of Androgen Deprivation Therapy Combined with Docetaxel for High Risk Prostate Cancer with a six-month treatment cycle.

The purpose of the study is to assess if the addition of darolutamide to ADT compared with ADT alone would result in superior clinical efficacy in participants with metastatic hormone-sensitive prostate cancer (mHSPC) by progression-free survival. The researchers want to learn how long it takes for the cancer to get worse (also known as "progression-free survival") by either increasing symptoms, new metastases, PSA rise or death. All participants will be on treatment and take darolutamide with ADT until their cancer spreads, they have a medical problem, or they leave the study. The results will then be compared with patients' results from another study who received ADT alone (CHAARTED). This study will also assess safety by gathering adverse event information throughout the duration of the study. An adverse event is any medical problem, related or not to study treatment that a participant has during a study. The study drug, darolutamide, is already available for doctors to prescribe to patients with prostate cancer that has not yet spread to other parts of the body. It works by blocking a protein called a receptor from attaching to a hormone called androgen that is found in men. This protein can also be found in prostate cancer cells. ADT is a treatment that doctors are currently able to prescribe to patients with mHSPC. ADT is used to lower the amount of the androgen hormone.

This trial studies the changes in long-term physician-scored genitourinary toxicity achieved in prostate cancer patients eligible for stereotactic radiation therapy when both patients and physicians have access to convincing but non-validated germline signature that can characterize patients as having a low or high risk of developing toxicity after radiation therapy. The information learned from this study may guide patients' and physicians' decisions on radiotherapy fractionation.

Approximately 50-60% of men undergoing salvage brachytherapy post cancer recurrence to the prostate have the disease controlled at 5 years. This study aims to integrate a local treatment to the prostate (brachytherapy) with a treatment involving 177Lutetium (Lu)- Prostate-Specific Membrane Antigen (PSMA) therapy. Differently than brachytherapy, 177-Lutetium-PSMA is thought to have its effect not only to the cancer cells within the prostate, but also to cancer cells located elsewhere in the body. Thus, the idea here is that by adding 177Lutetium (Lu)- PSMA early in the course of treatment we may be able to inactivate potential metastatic cells outside the prostate, while the prostate cancer within this organ still treated by the combination of brachytherapy and 177-Lutetium-PSMA.
