Filter by:This prospective study aims to collect data and blood biomarkers from patients undergoing Lu-PSMA therapy at the Erasmus MC. In doing so, it will provide real-world efficacy and safety data on the drug, gather dosimetry data and explore putative biomarkers to identify patients who most benefit from Lu-PSMA treatment.
The aim of this study is to evaluate the efficacy of 2 cycles of combinatory adebrelimab and stereotactic radiotherapy, followed by monotherapy adebrelimab in patients with metastatic castration-resistant prostate cancer. Dr. Yao Zhu from Fudan University Shanghai Cancer Center is the co-leading PI of this study.
Positron emission tomography (PET), an advanced diagnostic imaging technique, exploits the annihilation of positrons (e+) to delineate pathological alterations within diseased tissues. Integral to PET scanners are detector systems that transform gamma photons into fluorescent photons, thereby gleaning insights into the energy, time, and spatial distribution of gamma photons emanating from positron-emitting radiopharmaceuticals. Conventional PET scanners, bear a significant financial burden primarily due to their reliance on LSO (lutetium oxyorthosilicate) or LYSO (lutetium yttrium oxyorthosilicate) scintillation crystals. The exorbitant cost and limited availability of these crystal scintillators impede the widespread adoption of PET scanners. In a departure from conventional PET technology, the prototype J-PET scanner employed in this trial employs plastic scintillators, characterized by unique physical properties. This prototype is further equipped with bespoke software enabling three-photon imaging based on the annihilation of ortho-positronium (o-Ps) generated within diseased tissue. This study delves into the clinical applicability of PET scanners employing plastic scintillators, particularly investigating the feasibility of PET imaging using plastic scintillators where gamma quanta interact by mechanisms other than the photoelectric effect. Furthermore, this study endeavors to contemporaneously acquire and analyze data related to the lifetime of ortho-positronium (o-P) atoms emanating from routine radiopharmaceuticals. Additionally, it seeks to validate the utilization of a novel diagnostic indicator, termed the "positron biomarker," through a prospective study, comparing its efficacy to conventional diagnostic PET scanning methodologies.
The overall goal of the study is to improve equitable delivery of pre-Tumor genetic testing (TGT) counseling tool for Black or African American men with metastatic prostate cancer and evaluating the tool for implementation.
This is a phase 3, randomized, open-label study of opevesostat compared to alternative abiraterone acetate or enzalutamide in participants with metastatic castration-resistant prostate cancer (mCRPC) with respect to overall survival (OS) and to radiographic progression-free survival (rPFS) per Prostate Cancer Working Group (PCWG) Modified Response Evaluation Criteria In Solid Tumors (RECIST 1.1) as assessed by blinded independent central review (BICR) in participants with mCRPC previously treated with next-generation hormonal agent (NHA) and taxane-based chemotherapy. It is hypothesized that opevesostat is superior with respect to OS and rPFS per PCWG Modified RECIST 1.1 as assessed by BICR in androgen receptor ligand binding domain (AR LBD) mutation-negative and -positive participants.
Researchers leading this study hope to learn about the safety of combining the study drug relugolix with another study drug called itraconazole or ritonavir in prostate cancer. This study is for individuals who have advanced prostate cancer and plans to have medical castration (the use of medications or chemicals to lower hormone production in the testicles). Your participation in this research will last up to 1 month. The purpose of this research is to gather information on the safety and effectiveness of relugolix in combination with ritonavir or itraconazole. The goal of this research is to find out if combining two medications (relugolix and itraconazole or relugolix and ritonavir) could possibly lead to using less relugolix, which is an expensive drug.
The goal of this investigator-initiated, single-center, and randomized phase II trial is to investigate the potential synergistic effect of combining stereotactic body radiotherapy of a single soft tissue- or bone metastasis with ipilimumab and nivolumab in patients with mCRPC and perform translational analyses on tissue and blood, searching for predictive biomarkers of efficacy and toxicity. Participants will be randomized to receive ipilimumab and nivolumab with or without stereotactic body radiotherapy (SBRT).
Tumor bone metastasis refers to the metastasis of malignant tumors to the bone through lymph, blood or direct invasion to generate daughter tumors, which is the most common bone tumor. More than 40% of patients with malignant tumors will have bone metastasis, among which breast cancer, prostate cancer is more common, once the tumor cells occur bone metastasis, it means that the disease enters the advanced stage, posing a serious threat to the life safety of patients, therefore, early diagnosis of various primary malignant tumor bone metastases, can lay the foundation for clinical implementation of effective treatment measures. The laboratory of Hank F. Kung at the University of Pennsylvania has developed a new generation of 68Ga-labeled radiopharmaceutical P15-041 ([68Ga]Ga-HBED-CC-BP) based on existing phosphonate-targeting molecular probes (Figure 1). Data from preclinical studies indicate that P15-041 shows additional advantages in rapid and easy complex formation compared to current [68Ga]Ga-BPAMD, [68Ga]Ga-NO2AP-BP, [68Ga]Ga-DOTA- (ZOL). In vivo experiments, P15-041 showed good bone resorption and rapid renal excretion in normal mice. Haiyan Hong et al. [13] prepared multiple clinical doses of P15-041 and successfully evaluated it in patients, followed by intravenous P15-041, followed by a whole body PET/CT scan. Robert K. Doot et al. conducted dosimetric experiments on P15-041, analyzed the radioactive distribution of the drug in normal organs and the dynamic change of the dose of the drug in the body over time, and the results showed that P15-041 had high uptake in the bladder wall and bone cortex, blood and other tissues cleared quickly, and there was obvious radioactive enrichment in the myocardium in the early stage of imaging, and P15-041 had the potential to become a new generation of excellent phosphonate molecular probes.
This study will determine the safe initial injected activity of the radioligand therapy 177Lu-HTK03170 for the measurement of dosimetry and initiation of treatment in subjects with PSMA-positive, metastatic castrate resistant prostate cancer, (mCRPC). Subjects will receive treatment which will be escalated between cycles and personalized based on dosimetry calculations and imaging. In addition, antitumour activity will be measured by radiographic response, and further assessments of the treatment will be measured by CT imaging, ctDNA/ctRNA, PSA, PSMA PET/CT, and quality of life questionnaires. Subjects will be followed for 2 years or until they have progression and are switched to another systemic treatment.
It is a Phase 2 clinical trial of Pembrolizumab in combination with Carboplatin and Cabazitaxel in Aggressive Variant Metastatic Castration Resistant Prostate Cancer. It is divided into two parts: an induction period of 6 cycles of 3 weeks each cycle of Pembrolizumab+Cabazitaxel+Carboplatino and a maintenance phase of 15 cycles of 6 weeks each cycle of Pembrolizumab.
