Advanced Prostate Cancer

This is an open-label, multicenter Phase 1 study of DEC003M, in patients with advanced stage prostate cancer. The study consists of a dose-escalation phase to determine the dose for expansion, followed by a dose-expansion phase to evaluate preliminary antitumor activity, safety, and pharmacokinetics.

This phase II trial tests leuprolide acetate alone versus in combination with 177Lu-PSMA-617, with or without abiraterone acetate and prednisone, for the treatment of hormone-sensitive prostate cancer has spread to a limited number of anatomic sites at the time of initial diagnosis (de novo low volume metastasis) or that has come back after a period of improvement (recurrent). Standard of care treatment for prostate cancer usually includes androgen deprivation therapy, with or without abiraterone acetate and prednisone. Leuprolide acetate is a form of androgen deprivation therapy. It blocks the body from making testosterone (a male hormone) and estradiol (a female hormone). It may stop the growth of prostate cancer cells that need testosterone to grow. 177Lu-PSMA-617 is a type of radioconjugate drug. Upon administration, vipivotide tetraxetan targets and binds to prostate specific membrane antigen (PSMA)-expressing tumor cells. Upon binding, PSMA-expressing tumor cells are destroyed by 177Lu through the specific delivery of radiation. PSMA, a tumor-associated antigen and type II transmembrane protein, is overexpressed on prostate tumor cells. Abiraterone acetate is a type of anti-androgen drug. It blocks tissues from making androgens (male hormones), such as testosterone. This may cause the death of cancer cells that need androgens to grow. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Giving 177Lu-PSMA-617 in combination with leuprolide acetate, with or without abiraterone acetate and prednisone, may be more effective at treating patients with recurrent or de novo low volume metastatic hormone-sensitive prostate cancer than giving leuprolide acetate alone.

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and preliminary activity of RO7656594 in participants with advanced or metastatic prostate cancer. It will also identify recommended doses and regimens for RO7656594 for subsequent studies.

The purpose of this study is to evaluate the safety, pharmacokinetics (PK), and preliminary activity of GDC-1261 in participants with advanced or metastatic prostate cancer. It's also to identify a recommended dose(s) and regimen for GDC-1261 for subsequent studies.

This study is an open-label, multicenter Phase Ib/II clinical trial designed to evaluate the safety, tolerability, pharmacokinetics, and preliminary anti-tumor activity of QLC5508 in combination with NHA (abiraterone or enzalutamide), QLC5508 in combination with QLH12016, QLC5508 in combination with QLH12016 and NHA (abiraterone or enzalutamide), and QLH12016 in combination with NHA (abiraterone or enzalutamide) in subjects with advanced prostate cancer. The study consists of two stages: Phase Ib: is the combination dose-escalation stage, during which the recommended Phase II dose (RP2D) will be determined. Phase II is the efficacy exploration stage, in which, based on the RP2D established in Phase Ib, the therapeutic efficacy will be further evaluated in the target indication.

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.

The goal of this clinical trial is to test the efficacy a new psychosocial symptom management intervention called ENGAGE for patients with Stage IV breast, prostate, lung, or colorectal cancer. Participants will be randomized to ENGAGE or a Supportive Care intervention. Patient-reported outcomes will be assessed at baseline, 2 months, and 4 months.

The purpose of this clinical trial is to test the effectiveness of a dosing regimen of Teverelix DP castration rate defined as the cumulative probability of testosterone suppression to \< 0.5 ng/mL with the lower bound of the 95% confidence interval (CI) being \> 90% to meet the evaluation criteria for efficacy. The main question it aims to answer is: •Is the dosing regimen of Teverelix DP in this study effective at achieving the required testosterone suppression to castrate levels. Participants will * Receive a single loading dose consisting of 3 injections of teverelix DP (180 mg IM + 2x 180 mg SC) on Day 1. * Receive a maintenance dose consisting of 2 injections (2X 180 mg SC) from week 4 (Day 29) and every 6 weeks up to Week 16 (Day 113). * The first 30 enrolled participants will have 24-hour continuous Holter monitoring performed and 24-hour PK samples will be drawn. The results of this study are intended to support dose selection and provide supportive safety and PK/PD data to enable advancement into a subsequent Phase 3 clinical study in patients with advanced prostate cancer who are at high cardiovascular risk.

To look at the safety and effectiveness of stereotactic body radiation therapy (SBRT) in treating advanced or high-risk prostate cancer.

This study will use Prostate Specific Membrane Antigen (PSMA) and (18)F-Fluorodeoxyglucose Positron Emission Tomography (FDG PET) imaging in patients with advanced prostate cancer to learn about tumor biology across disease stages and during treatment. This may help with treatment selection and potential response monitoring in the future.

Multicenter, observational, prospective, study. All patients will be treated and monitored according to the local clinical practice. No additional procedures/patient visits in comparison with the usual clinical practice are planned for the study.

The RING study is a European registry collecting real-world data on advanced prostate cancer (APC) imaging. It aims to evaluate the role of next-generation imaging (NGI), such as PET/CT and whole-body MRI, in detecting and monitoring the disease compared to conventional imaging. Men aged 18 or older with histologically confirmed prostate cancer are eligible to participate in the study if they require imaging to assess potential metastases, either at diagnosis or after relapse and sign a consent form. Patients will receive standard care with no experimental treatments. Imaging and treatment decisions will follow routine clinical practice. Data will be collected from medical records and analysed for research. This study will help doctors understand when NGI should be used, how it affects treatment decisions, and its impact on patient outcomes.
