NCT07198633
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.
NCT07426094
Patients with prostate cancer and pelvic lymph node involvement (cN1M0) identified on PSMA PET imaging represent a biologically aggressive yet potentially curable disease population. Contemporary management relies on multimodality treatment combining definitive radiotherapy to the prostate and pelvic lymph nodes with long-term androgen deprivation therapy (ADT), often intensified with androgen receptor pathway inhibitors. Despite these advances, a substantial proportion of patients still develop distant metastatic disease, highlighting the need to optimize local-regional treatment strategies in the era of molecular imaging. The introduction of PSMA PET has fundamentally altered staging accuracy in prostate cancer, enabling earlier and more precise detection of pelvic nodal disease. However, most existing evidence guiding radiotherapy dose prescription in node-positive prostate cancer originates from the pre-PSMA era. As a result, it remains unclear how best to integrate prostate-directed and nodal-directed dose escalation strategies when disease extent is defined by modern molecular imaging. In particular, it is unknown whether long-term disease control is primarily driven by durable intraprostatic tumor eradication, by aggressive treatment of involved lymph nodes, or by a combination of both. PRO-BOOST-N is a prospective, multicenter, randomized phase II/III clinical trial designed to address this critical evidence gap. The trial evaluates prostate-first versus combined prostate and nodal dose escalation strategies in patients with PSMA PET-staged node-positive (cN1M0) prostate cancer treated within a standardized ultrahypofractionated whole-pelvis radiotherapy framework. All enrolled patients indicated for definitive treatment undergo mandatory baseline PSMA PET/CT to confirm pelvic lymph node involvement and exclude distant metastatic disease. All patients receive a uniform radiotherapy backbone consisting of ultrahypofractionated whole-pelvis radiotherapy delivered in five fractions, combined with long-term ADT. Use of androgen receptor pathway inhibitors is permitted and encouraged according to contemporary clinical practice and local availability, ensuring the relevance of the trial to real-world treatment settings. Using a 2×2 factorial randomized design, PRO-BOOST-N evaluates two independent treatment factors. The primary randomized comparison assesses whether ablative prostate dose escalation improves oncologic outcomes compared with contemporary SBRT-based definitive prostate radiotherapy without additional boost. Prostate dose escalation may be delivered using one of three protocol-defined modalities-high-dose-rate brachytherapy, low-dose-rate brachytherapy, or single-fraction SBRT-according to institutional expertise. This comparison directly tests the hypothesis that durable intraprostatic disease control is the dominant determinant of long-term systemic disease suppression in node-positive prostate cancer. The key secondary, hierarchically tested comparison evaluates the role of nodal dose escalation by comparing two predefined dose levels delivered to PSMA PET-positive pelvic lymph nodes. These dose levels reflect intermediate versus higher nodal boost strategies based on biologically effective dose concepts specific to prostate cancer radiobiology. To ensure patient safety and protocol feasibility, organ-at-risk-driven nodal dose de-escalation is permitted within the higher-dose arm, without altering randomization assignment. The primary endpoint of the trial is metastasis-free survival. Secondary endpoints include overall survival, radiographic progression-free survival assessed primarily using PSMA PET imaging, intraprostatic and regional nodal control, time to castration-resistant prostate cancer, time to next systemic therapy, treatment-related toxicity graded according to CTCAE version 5.0, and patient-reported outcomes assessing urinary, bowel, sexual, and global quality of life. By prospectively and hierarchically evaluating prostate and nodal dose escalation strategies within a modern PSMA PET-guided and ultrahypofractionated radiotherapy platform, PRO-BOOST-N aims to define the optimal radiotherapy intensification approach for patients with node-positive prostate cancer. The results of this study are expected to directly inform clinical practice, guideline development, and future treatment individualization in the PSMA PET era.
NCT06463457
This research study is being done to determine the rate of testosterone recovery after completing two years of treatment with the combination of relugolix and darolutamide as well as to assess the safety of the drugs when administered in combination. The names of the drugs in this study are: * Relugolix (a type of gonadotropin-releasing hormone receptor antagonist) * Darolutamide (a type of androgen receptor antagonist)
NCT06130995
The goal of this clinical trial is to test how effective and safe it is to use a combination of two medications, relugolix and enzalutamide, in patients with advanced prostate cancer. We want to see if this combination can help improve the chances of curing the cancer and make the patients live longer without the cancer getting worse. The main questions we want to answer in this study are: * Can using relugolix and enzalutamide together help increase the chances of curing high-risk advanced prostate cancer? * Does this combination treatment help patients live longer without their cancer getting worse? Participants in this study will be asked to take relugolix and enzalutamide as part of their cancer treatment. They will also undergo Radiation Therapy or prostatectomy, which are standard treatments for this type of cancer.

NCT04117594
In prostate cancer bone is the most common site for cancer spread, causing pain, fractures, nerve compression and death. New therapies are available for treating bone disease from cancer and this means that by maintaining patients on drugs that are effective and switching patients to other drugs when current treatment becomes ineffective, patients can be maintained 'better for longer'. However, to do this, it is necessary to accurately tell whether a given treatment is working or not. In this study, the investigators will perform whole body MRI scans, which include a special scan called diffusion-weighted MRI (DWI MRI) that can provide more information about the participants extent of disease. The investigators aim to show that this test is better than the standard tests of CT and bone scan currently used in the NHS to monitor bone disease. The information from this study will be used to test a special software so that the test may more widely benefit patients across the NHS in the future.
