Active clinical trials for "Prostatic Neoplasms"

This clinical trial is evaluating a drug called AC176 in Chinese participants with metastatic castration resistant prostate cancer (mCRPC) who have progressed on at least one prior systemic therapy. The main goals of this study are to: Evaluate the safety and tolerability of AC176, evaluate pharmacokinetics and preliminary antitumor activity of AC176

Trans-perineal focal laser ablation represents a promising alternative focal therapy option for patients with low-risk or favorable intermediate risk prostate cancer. FLA has been extensively utilized for over a decade in the treatment of PCa using different anatomical approaches. The proposed study differs from past ones in that a trans-perineal approach with reduced risk of infection will be used in contrast to the current trans-rectal approach. In addition, high frequency micro-ultrasound imaging will be used to enhance imaging and facilitate accurate needle placement and FLA of the index lesions. The aim of this study is to evaluate FLA as a potential optimal therapeutic intervention based on safety, ease of use, efficacy, and cost.1 FLA holds promise for the management of localized tumors. The combination of the trans-perineal focal laser ablation and micro-ultrasound imaging will enable targeted trans-perineal fusion laser induced thermal therapy of prostate cancer lesions. This approach offers significant potential advantages over traditional interventions including: Improved dynamic ultrasound imaging of the lesion to be treated compared to traditional ultrasound techniques. Enhanced ability to visualize and spare critical structures within the prostate, including the bladder neck, neurovascular bundle (NVB), urethral sphincter and organs in close proximity including the rectum. Sparing these structures should translate into improved preservation of ejaculation, limited changes in sexual function and minimal transient incontinence following treatment.

Researchers are looking for a better way to treat men at high-risk of biochemical recurrence (BCR) of prostate cancer. BCR means that in men who had prostate cancer and were treated by either surgery and/ or radiation therapy, the blood level of a specific protein called PSA rises. PSA is a marker of prostate cancer cells activity. The PSA increase means that the cancer has come back even though conventional imaging such as computed tomography (CT) scans, magnetic resonance imaging (MRI) and bone scans does not show any lesion of prostate cancer. Recently a more sensitive imaging method called prostate-specific membrane antigen [PSMA] positron emission tomography [PET]) /computed tomography [CT]) scan may identify prostate cancer lesions not detectable by conventional imaging. Men with BCR have a higher risk of their cancer spreading to other parts of the body, particularly when PSA levels raised to a certain limit within a short period of time after local therapies. Once the cancer spreads to other parts of the body, it can become even harder to treat. In men with prostate cancer, male sex hormones (also called androgens) like testosterone can help the cancer grow and spread. To reduce androgens levels in these patients, there are treatments that block androgens production in the body called androgen deprivation therapy (ADT). ADT is often used to stop prostate cancer. Another way to stop prostate cancer growth and spread is to block the action of androgen receptors on prostate cancer cells called androgen receptor inhibitors (ARIs). The new generation ARIs including darolutamide can block the action of androgens receptors and are available for the treatment of prostate cancer in addition to ADT. It is already known that men with prostate cancer benefit from these treatments. The main objective of this study is to learn if the combination of darolutamide and ADT prolongs the time that the participants live without their cancer getting worse, or to death due to any cause, compared to placebo (which is a treatment that looks like a medicine but does not have any medicine in it) and ADT given for a pre-specified duration of 24 months. To do this, the study team will measure the time from the date of treatment allocation to the finding of new cancer spread in the participants by using PSMA PET/CT, or death due to any cause. The PSMA PET/CT scans is performed using a radioactive substance called a "tracer" that specifically binds to the prostate-specific membrane antigen (PSMA) which is a protein often found in large amounts on prostate cancer cells. To avoid bias in treatment, the study participants will be randomly (by chance) allocated to one of two treatment groups. Based on the allocated treatment group, the participants will either take darolutamide plus ADT or placebo plus ADT twice daily as tablets by mouth. The study will consist of a test (screening) phase, a treatment phase and a follow-up phase. The treatment duration is pre-specified to be 24 months unless the cancer gets worse, the participants have medical problems, or they leave the study for any reason. In addition, image guided radiotherapy (IGRT) or surgery is allowed and your doctor will explain the benefits and risks of this type of therapy. During the study, the study team will: take blood and urine samples. measure PSA and testosterone levels in the blood samples do physical examinations check the participants' overall health examine heart health using electrocardiogram (ECG) check vital signs check cancer status using PSMA PET/CT scans, CT, MRI and bone scans take tumor samples (if required) ask the participants if they have medical problems About 30 days after the participants have taken their last treatment, the study doctors and their team will check the participants' health and if their cancer worsened. The study team will continue to check this and regularly ask the participants questions about medical problems and subsequent therapies until they leave the study for any reason or until they leave the study for any reason or until the end of the study, whatever comes first.

This phase Ib trial tests the safety, side effects, and best dose of autologous anti-prostate stem cell antigen (PSCA)-chimeric antigen receptor (CAR)-4-1BB/TCRzeta-CD19t-expressing T-lymphocytes (PSCA-CAR T cells), plus or minus radiation, in treating patients with castration-resistant prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Castration-resistant prostate cancer continues to grow and spread despite the surgical removal of the testes or medical intervention to block androgen production. CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. Giving PSCA-targeting CAR T-cells, with or without radiation, may kill more tumor cells in men with castration-resistant prostate cancer.

The main objective of this project is to establish a shared comprehensive and systematic protocol for a multicenter prospective registry of patients undergoing salvage cryoablation of the prostate (SCAP). Our study hypothesis is that SCAP constitutes an effective and safe approach to treat local prostate cancer recurrence after brachytherapy or external beam radiation therapy (EBRT).

New androgen pathway targeting agents (ARTA), including Abiraterone acetate, Apalutamide and Enzalutamide, are approved and used in treatment of metastatic hormonal sensitive prostate cancer(mHSPC). However, the development of castration-resistance prostate cancer(CRPC) is only a matter of time. The use of sequential ARTAs in mCRPC showed limited benefit in retrospective series and prospective trials. Therefore this sequence should be avoided because of known cross resistance and the availability of chemotherapy and poly adenosine diphosphate-ribose polymerase(PARP) inhibitors (if a relevant mutation is present). Recently, a randomized controlled trial(RCT), the ABIDO-SOGUG, indicated that compared with docetaxel, maintaining Abiraterone added to docetaxel in chemotherapy-naive patients who have experienced cancer progression to Abiraterone treatment could not improve radiographic progression-free survival or the other endpoints.However, another RCT, the PRESIDE trial, indicated that in patients who had progressed on Enzalutamide, continued Enzalutamide treatment in combination with docetaxel led to a significant improvement of PFS compared with placebo plus docetaxel. The aims of this trial is to assess both the efficacy and safety of docetaxel in combination with Enzalutamide as first-line treatment in mCRPC patients progressed on Abiraterone.

This is a randomized study to evaluate the risk of major adverse cardiovascular events (MACE) for relugolix compared with leuprolide acetate. This study will collect clinical and cardiovascular risk factor data on patients ages 18 and older who are receiving relugolix or leuprolide acetate for their prostate cancer or as adjunct to radiation therapy with a treatment plan to be on androgen deprivation therapy (ADT) for at least one year.

This phase I study will assess the toxicity profile and efficacy of SBRT (Stereotactic body radiotherapy) in patients with localized prostate cancer who are considered candidates for post-prostatectomy radiation.

This is a Phase III, international, multicentre, randomised, double-blinded placebo controlled trial, evaluating the efficacy and safety of ADT +/- darolutamide in castration-naïve de novo metastatic prostate cancer patients with vulnerable functional ability who have not elected for docetaxel or other androgen receptor pathway inhibitors.

The purpose of this Phase I/II study is to determine the safety and effectiveness of up to 5 study drugs used together for the treatment of solid tumor cancers. The drugs are hydroxychloroquine, nelfinavir, metformin, dasatinib and sirolimus.
