Active clinical trials for "Prostatic Neoplasms"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with G-CSF may make tumor cells more sensitive to the chemotherapy drug and may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of mitoxantrone plus G-CSF in treating patients with metastatic prostate cancer that has not responded to hormone therapy.

The purpose of this research study is to measure the hypoxia (low oxygen condition) in prostate cancers and its effect in survival. In this study, investigators will assess hypoxia by magnetic resonance imaging (MRI) and create a hypoxia score. Investigators will study the hypoxia score and how it correlates (if any) to the disease aggressiveness as well as its effect on the treatment outcomes.

The purpose of this study is to determine the safety and efficacy of 177 Lu -labeled PSMA ligand(PSMA-I＆T) in the treatment of mCRPC in Asianethics.

The aim of this trial is to evaluate SHR3680 combined with SHR3162 and SHR3680 single drug to improve Metastatic Castration Resistant Prostate Cancer Patients whether the patient's overall survival (OS) is superior to placebo.

The death of prostate cancer patients is mainly due to metastatic castration-resistant prostate cancer. Though some new therapies has been tried to prolong the life-span of mCRPC patients, a dilemma was encountered for the drug-resistance. The PSMA RLT has been tested its efficacy and safety for the therapy of these patients. In our clinical trial, a new PSMA ligand will been used to be labeled with Ac225. This will be a prospective pilot clinical trial. 20 mCRPC patients who was incapable of 2rd ADT or chemotherapy will be recruited in this clinical tiral. The efficacy and safety of 225Ac-PSMA will be evaluated after the administration.

This study is an investigator initiated clinical study. A prospective, single arm unblinded, open label study will be carried out to determine the feasibility of recruitment, retention and adherence of 36 prostate cancer survivors who have been on androgen deprivation therapy within the last 5 years for a lifestyle modification intervention.

HDR brachytherapy in conjunction with pelvic SABR in high tier intermediate and high risk prostate cancer patients can provide a safe and effective means of radiotherapy dose escalation. Utilizing multiparametric MRI to focally boost the dominant intraprostatic lesion during HDR brachytherapy is safe and feasible.

This is a single dose, randomized, single blind, parallel group study to evaluate the testosterone suppressive effect in healthy male volunteers of a novel leuprolide acetate 3.75mg depot vs market reference leuprolide acetate 3.75mg depot. The safety, tolerability and the pharmacokinetic properties of the investigational drug and the control drug will also be assessed.

Currently radiotherapy for prostate cancer is directed using scans or X-Rays, which ensures the radiotherapy treatment 'hits the target' and avoids the healthy tissues around the prostate. There are two current methods of radiotherapy image guidance- either placing small gold seeds into the prostate and taking XRays or doing a small CT scan of the prostate region each day. Neither of these methods are perfect and have drawbacks and inaccuracies. The best way to see the prostate is with an MRI scan - this shows the edge of the prostate much more clearly and can even show the area of most aggressive cancer within the prostate. Shortly the investigators will have the ability to use a new machine - an MR-Linac - which combines an MR scanner and a radiotherapy machine. As well as giving the investigators a clearer picture, and enabling the investigators to keep watching the prostate while the participant has their treatment (not currently possible with standard machines) this new machine will also allow the investigators to change the radiotherapy plan if they can see that the internal anatomy has shifted day to day. Currently the investigators have to give the same radiotherapy plan each day, which means the investigators have to treat a 'safety margin' around to prostate to allow for these day to day anatomy changes (e.g. rectal filling). The aim of this study is to assess the technical feasibility of delivering radical radiotherapy for prostate cancer using the MR-Linac, including the feasibility of changing the radiotherapy plan on a daily basis to mirror internal anatomy changes. The investigators will recruit 30 patients with localised prostate cancer who need radiotherapy. The team will deliver the same dose in the same number of days i.e. the same as standard radiotherapy. Side effects will also be assessed by physicians and using patient questionnaires.

Einstein Healthcare Network in North Philadelphia serves a predominantly underserved medical community. The investigators routinely see patients who cannot afford absorbent pads after prostate surgery, which helps with quality of life secondary to urinary incontinence. The investigators will provide absorbent pads to participants who would be unable to afford them. The investigators hypothesize that providing absorbent pads for 6 months will result in improved quality of life in regards to management of urinary incontinence after radical prostatectomy.
