Active clinical trials for "Prostatic Neoplasms"

The present study in patients with Prostate cancer and biochemical failure after surgery and/or radical-postoperative Radio Therapy (RT) will evaluate if PET/CT with 18F-JK-PSMA-7 compared to PET-CT 18F-Choline is able to identify the early pattern of biochemical recurrence and/or metastatic sites, so that the patient could be better managed, with a benefit in survival.

Prostate Stereotactic ablative body radiotherapy (SABR) is an established technique that delivers radiation in a non-invasive approach for men with prostate cancer. The treatment regimen is given in total of 5 fractions with one treatment per day at every other day or weekly sessions. Ultra-hypofractionated radiotherapy (UHRT) is an emerging monotherapy for localized prostate cancer however, several trials have observed demonstrating superior biochemical control of a two-fraction (HDR) over single-fraction approach. The study aims to compare an experimental shorter course of prostate ultra-hypofractionated radiotherapy (UHRT) that will deliver what is expected to be an equivalent amount of radiation as given in the standard 5 treatment regimen. UHRT is given in 2 treatments with one treatment a week for 2 consecutive weeks.

The purpose of the study is to determine if a radiopaque hydrogel rectal spacer, SpaceOAR Vue®, can be used in place of fiducial markers when aligning patients for radiotherapy. The investigator hypothesizes that the alignment of the patient based on the rectal spacer will be similar to the alignment of the patient with fiducial markers.

This is a single center single arm prospective pilot study investigating the safety of high dose rate (HDR) brachytherapy as monotherapy delivered in 2 fractions 3 hours apart. HDR monotherapy has been established as safe and effective in this context, however previous studies have delivered 2 fractions on separate days, or at least 6 hours apart. Clinically, this regimen, if shown to be safe and effective in future studies, has the potential to reduce operative resources and logistical stresses on brachytherapy departments.

This is a prospective, open, randomized phase II trial.

The aim of this study is to assess the progression free survival (PFS) of SABR alone and SABR + 177Lu-prostate-specific membrane antigen (PSMA) in patients with oligometastatic prostate cancer undergoing PSMA positron emission tomography (PET) staging.

The study aims to develop educational media interventions to prepare Latinx Spanish-speaking radiation oncology patients for a course of breast or prostate cancer radiation therapy and to foster receptivity and informed decision-making around cancer clinical trial participation.

The AFFIRM trial tests the safety and clinical feasibility of MR-guided hypofractionated focal boost radiotherapy for patients with locally advanced prostate cancer. External beam radiotherapy combined with androgen deprivation therapy is considered as the treatment of choice for patients with locally advanced non-metastatic prostate cancer with seminal vesicle invasion.The long-term results of the multicentre phase III study (FLAME trial) showed that addition of an isotoxic focal boost to the intraprostatic lesion improves biochemical disease free survival in intermediate to high-risk patients without impacting toxicity and quality of life. This focal boost strategy is now proven for a conventional fractionation scheme (35 fractions). The current trend in radiotherapy for prostate cancer is (extreme) hypofractionation, reducing the number of fractions. For locally advanced prostate cancer, however, the data on extreme hypofractionation are scarce.

Background: Prostate cancer does not trigger a strong immune response in the body. Hormone therapy, to reduce levels of testosterone in the body, can be helpful to treat some prostate cancers. However, castration-resistant prostate cancer (CRPC) keeps growing even when the testosterone is reduced to a very low level. Men with metastatic CRPC survive an average of only 3 years. More effective treatments are needed. Objective: To test whether an immunotherapy drug (N-803), alone or in combination with other drugs, can help treat CRPC. Eligibility: Males aged 18 or older with CRPC. Prior treatment with testosterone-lowering therapy is required. Design: Participants will be screened. They will have blood and urine tests. They will have a CT scan of the chest, abdomen, and pelvis. They will continue to receive hormone therapy for prostate cancer. Participants will come to the NIH clinic once a week for the first 4 weeks. Then they will come once every 2 weeks. Visits will last up to 8 hours. The study will continue up to 3 years. All participants will receive N-803 once every 2 weeks. The drug is injected just under the skin with a small needle. Some participants will receive N-803 plus another drug (brachyury vaccine). This drug is also injected under the skin with a small needle. Some participants will receive N-803 plus a different drug (bintrafusp alfa) once every 2 weeks. This drug is given through a tube attached to a needle placed in a vein in the arm. Some participants may receive all 3 drugs. Participants will have imaging scans every 12 weeks.

This is a multicenter, correlative study to existing Lutetium based prostate-specific membrane antigen (PSMA)-targeted radioligand therapy (RLT) trials and uses.
