Prostate Cancer Recurrent

This is a randomized, open-label, pilot study assessing the impact of a short course of bicalutamide on PSMA expression in patients with prostate cancer belonging to the intermediate unfavorable or high risk group, who have low levels of PSA. Adult patients with biochemically recurrent prostate cancer (BCR PCa) who have a PSA of less than 1.0 ng/mL and who have undergone complete prostatectomy and/or will be undergoing radiotherapy, in combination with standard of care bicalutamide, will be recruited to this study. Patients will be randomized in a 1:1 ratio into Group A (baseline PSMA PET/CT only with bicalutamide standard of care) or Group B (baseline PSMA PET/CT and an additional PSMA PET/CT after 2 weeks of bicalutamide).

This is an interventional, single-centre, single-arm, non-randomized, prospective, feasibility trial investigating salvage MR-guided High-Dose-Rate brachytherapy for prostate bed recurrence after postoperative radiotherapy.

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, metformin, sirolimus, dasatinib and nelfinavir and are given orally.

For men with an aggressive form of prostate cancer, finding the right and effective treatment right away is challenging. Many of these men face a high risk of cancer recurrence: about half experience a relapse after surgery, and more than a third after undergoing radiation therapy. Men with metastatic prostate cancer have particularly poor prognoses, with a five-year survival rate of only 30% to 50%. In short, it is difficult to predict which treatment, or combination of treatments, will lead to longer survival for this group of men with aggressive (metastatic) prostate cancer. In the laboratory, it is possible to grow small samples of tumors into 3D mini-tumors. These mini-tumors retain the characteristics of the patient's original tumor tissue. Various treatments can be tested on these 3D mini-tumors to determine which therapy is most effective for each individual case. There are currently two techniques available for creating these 3D mini-tumors in the lab. In this project, we aim to investigate which of these two techniques works best in order to test and personalize treatments.

To compare the diagnostic performance of 18-F PSMA PET/CT and CT alone in initial staging, assessment of therapy response, as well as evaluation of biochemical recurrence of prostatic cancer patients The main question it aims to answer is: Does 18-F PSMA PET/CT have a superior role over CT in evaluation of prostatic cancer patients?

The goal of this clinical trial is to learn if fezolinetant can treat hot flashes (vasomotor symptoms) in men with prostate cancer undergoing androgen deprivation therapy. The main questions it aims to answer are: * Does fezolinetant improve the frequency and severity of hot flashes? * Does fezolinetant cause any harm to the liver? * Does fezolinetant improve quality of life, sleep quality, fatigue, mood, sexual function, and metabolic parameters? Researchers will compare how people respond to fezolinetant versus a placebo, which does not contain any active medicine. Participants will: * Take fezolinetant or a placebo every day for 4 weeks * Visit the clinic once every 2 weeks for checkups and tests * Keep a diary of the number of times and intensity that they experience hot flashes

Analysis of peripheral immune cells before, during, and after brachytherapy treatment. Corresponding analysis of tissue samples collected during brachytherapy treatment.

A multicenter, open-label, prospective Phase III clinical trial to evaluate INR101 injection for PET/CT imaging in participants with suspected recurrent prostate cancer after radical treatment.

The aim is to investigate whether the addition of short-term androgen deprivation therapy (ADT) during 1 month or short-term ADT during 6 months together with an androgen receptor targeted therapy (ARTA) to metastasis-directed therapy (MDT) significantly prolongs poly-metastatic free survival (PMFS) and/or metastatic castration-refractory prostate cancer free survival (mCRPC-FS) in patients with oligorecurrent hormone sensitive prostate cancer.

This trial is a phase I open-label, single center study designed to evaluate the safety, tolerability and preliminary efficacy of the bispecific prostate specific membrane antigen (PSMA) and cluster of differentiation protein 3 (CD3) antibody CC-1 in men with biochemical recurrence (BCR) of prostate cancer (PC). The PSMA binder in CC-1 reacts with tumor cells and also binds to tumor vessels, thereby allowing for a dual mode of anti-cancer action. CC-1 was developed in a novel format, which not only prolongs serum half-life, but most importantly reduces off-target T-cell activation with accordingly reduced side effects. The study entails a part I (dose escalation part) to identify the maximally tolerated dose of CC-1, which then will be further evaluated in part II of the study (dose expansion part). After application of two low doses as safety steps in the first cycle, CC-1 will be applied twice weekly for three consecutive weeks within 4 week cycles as a short-term intravenous infusion (3 hours). The planned trial ultimately shall define the recommended phase II dose (RP2D) of CC-1 in the disease setting of BCR of PC.

Prospective single-center one-arm phase II study in patients with prostate cancer and confirmed biochemical recurrence (BCR) with PSA of ≥ 0.2 ng/ml after radical prostatectomy (RP) or PSA \> nadir + 2ng/ml after radiotherapy (RT) but not radio-morphological local recurrence after primary therapy with curative intent receive systemic therapy with only 2 cycles of highly standardized (3 GBq in first cycle and 6 GBq in the second cycle) PSMA-RLT at 6-week intervals.

This observational study was designed to evaluate progression free survival after PSMA-PET/CT based salvage approach for patients affected by biochemical relapse after radical prostatectomy.
