Safety, Efficacy and Pharmacokinetics of TT00420 Tablets Combined With Novel Endocrine Therapy in Patients With Metastatic Castration-resistant Prostate Cancer (mCRPC)

The goal of this clinical trial is to learn if tinengotinib combined with darolutamide or enzalutamide works to treat participants with metastatic castration-resistant prostate cancer (mCRPC) who have progressed on prior androgen receptor pathway inhibitors (ARPIs). It will also learn about the safety of the combination therapy. The main questions it aims to answer are: 1. If participants with mCRPC can benefit from the combination therapy of tinengotinib plus one ARPI? 2. What medical problems do participants have when taking the combination therapy? Participants will take tinengotinib with darolutamide or enzalutamide to find the optimal dose and regimen of tinengotinib for the combination therapy in stage A. In stage B, participants will take preferred combination regimen of tinengotinib plus darolutamide/enzalutamide identified in stage A. In stage C, researchers will compare selected combination therapy versus standard treatment and/or monotherapy to see if the combination therapy works better.

Prostate Cancer Postoperative Stereotactic Body Radiotherapy With Adaptive Technology for Minimizing Toxicity

Single-arm, prospective registry study assessing changes in acute patient-reported urinary (GU) and gastrointestinal (GI) quality of life at the 24-month post-treatment time point following magnetic resonance imaging (MRI)-guided or computed tomography (CT)-guided stereotactic body radiotherapy (SBRT) delivered to the prostate bed +/- pelvic lymph nodes. The decision to offer an adaptive treatment will be at the clinician's discretion.

FAPI PET Imaging - An Exploratory Study

This study is testing a new imaging tracer called \[18F\]FAPI-74 with PET scans. Researchers want to find out how well this tracer shows certain diseases in the body, including several types of cancer and some non-cancer conditions like fibrosis and sarcoidosis. \[18F\]FAPI-74 attaches to a protein found on cells that are active in tumors and areas of scarring or inflammation. This may help doctors see these areas more clearly than with imaging methods used today, especially in diseases where current scans do not work well. People who join this study will get one injection of the tracer into a vein, then have one PET/CT or PET/MR scan. This takes about 2 hours in total. Researchers will compare the results with imaging the participant already had as part of their regular care, such as other PET scans, CT, or MRI. No extra treatment is given, and no other visits are needed. The study will take place at 5 hospitals in Switzerland and plans to include about 770 adults with a confirmed or suspected diagnosis of one of the conditions being studied. The main goal is to see how clearly the tracer shows up on the scan. Researchers will also look at whether this new scan changes how confident doctors feel about a diagnosis, or changes the patient's treatment plan.

Study of Alpha Radioligand Therapy AB001 in Patients With Metastatic Castration Resistant Prostate Cancer (mCRPC)

This Phase 1 study will evaluate the safety, tolerability, and preliminary effectiveness of AB001, an alpha-emitting radioligand targeting prostate-specific membrane antigen (PSMA), in patients with advanced prostate cancer who are either 177Lu-PSMA naïve or experienced. The study includes dose escalation to identify a recommended dose and dose expansion to further assess safety and anti-tumour activity. Primary objectives are to characterize the safety profile and determine the optimal dose and schedule for future studies

Comparison of Peak Expiratory Flow Changes After Robot-Assisted Versus Open Radical Prostatectomy

This prospective, randomized controlled trial aims to compare perioperative respiratory changes in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALRP) and open radical prostatectomy (ORP). The primary outcome is the change in peak expiratory flow (PEF) from the preoperative period to the early postoperative (2nd hour) period. Secondary outcomes include PEF recovery at 24 hours, and correlations between PEF change and intraoperative factors such as Trendelenburg angle, pneumoperitoneum duration, and ventilatory parameters.

Treatment of Patients With Progressive mCRPC With 177Lu-PSMA-617

The purpose of this study is to evaluate the safety and tolerability of Lutetium-177-PSMA-617 (PLUVICTO) in patients with metastatic castration-resistant prostate cancer (mCRPC) and extensive bone metastases, which appear as a "super scan" pattern on a bone scan. Pluvicto is FDA-approved, but patients with super scan bone scans were previously excluded from the VISION clinical trial, leaving a knowledge gap. The study will enroll up to 30 men with metastatic castration-resistant prostate cancer, with an initial dosing approach that differs from the standard dose. The safety and tolerability of PLUVICTO will be evaluated in this study, with a focus on identifying the optimal dose for this population. This study addresses an important gap in understanding how Pluvicto performs in mCRPC patients with super scan findings.

Study on Human Bioequivalence of Triprerelin Acetate for Injection

To investigate the pharmacokinetics of triprerelin acetate for injection and triprerelin acetate (Dufferin ®) for injection of reference preparation in patients with prostate cancer by single intramusculodynamic injection in fasting state, and to evaluate the bioequivalence of the two formulations in fasting state.
