Filter by:To assess the safety of treating men with oligometastatic prostate cancer with the following therapy: (1st) Systemic chemo-hormonal therapy with up to 6-months (~24 weeks) of adjuvant androgen deprivation and up to 6 cycles of chemotherapy, (2nd) definitive local tumor control with adjuvant radiation therapy, and (3rd) consolidative stereotactic radiation to oligometastatic lesions. The men will receive a total of 2 years of androgen deprivation. Androgen blockade will be the same throughout the course of treatment.
The purpose of this study is to find the highest dose level of the study drug, 177Lu-PSMA-617 that can be given without severe side effects for advanced prostate cancer.
Prostate Cancer (PC) is the most frequent cancer in men, accounting for 21% of new cases of cancer in men in the United States. Among the four most incident tumors (breast, lung and colorectal cancer); prostate cancer is the only that does not have any predictive biomarker to guide the treatment. Even though the molecular heterogeneity of PC is well-documented, treatment has not been molecularly stratified and the need for genetic prognostic and predictive markers is critical. DNA repair defects (DRD), mainly in the Homologous Recombination (HR) pathway (such as BRCA1, BRCA2, ATM and CHEK2) are emerging as potential biomarkers in prostate cancer. It is well known BRCA1 and BRCA2 carriers have better Progression-Free Survival (PFS) and Overall Survival (OS) than non-carriers in ovarian cancer. Differently than ovarian tumors that BRCA mutations provides a good prognosis, PC patients who harbor HR defects have a higher Gleason score 6, an increased risk of recurrence and poor prognosis. The predictive role of DRD in PC was demonstrated in a recent trial using Olaparib, a PARP inhibitor, in DRD carriers. This trial showed 88% of response rate with Olaparib, a PARP inhibitor that acts in HR pathway by synthetic lethality. Recent data demonstrated important association between HR deficient high-grade serous ovarian cancer (HGSOC), high neoantigen load and high expression of PD-1/PD-L1 compared with HR proficient HGSOCs 10. This study showed that BRCA1 and BRCA2 mutations increase the number of tumor-infiltrating lymphocytes (TILs) and confer a better prognosis. The unprecedented success of immunotherapy in malignant disorders has provided evidence that the patient's immune system can be improved to attack established tumors, mainly melanoma, non-small cell lung cancer and kidney cancer. A high mutational burden increases the likelihood of the development of specific neoepitopes that would confer clinical benefit from CTLA-4 and PD-1 blockade. These data showed that specific DNA repair defects increase the mutational burden, the expression of PD-1/PD-L1 and TILs; and could improve the response to immunotherapy in cancer. This rationale was already tested in a trial that evaluated the PD-1 checkpoint inhibitor Pembrolizumab in mismatch-repair deficient patients, a kind of DNA repair defect by definition. This important trial showed that this DRD predicted clinical benefit of immune checkpoint blockade in many types of cancer, especially colorectal cancer.
The investigational protocol describes a small case series designed to compare three imaging modalities for use in visualizing prostate cancer. The three modalities to be tested are: transrectal micro-ultrasound , and conventional resolution transrectal ultrasound (LR-TRUS) (both as implemented on ExactVu, the multi-frequency novel micro-ultrasound system under investigation), and multi-parametric MRI (mpMRI). These modalities will be used for guiding systematic (standard, random, extended sextant) plus image-guided targeted prostate biopsies among men with known cancer and an indication for prostate biopsy. In the case of mpMRI, biopsy will be performed under micro-ultrasound guidance with the radiology report used for targeting.
The goal of this clinical research study is to learn about biomarker changes in patients who have primary prostate cancer after receiving Darzalex (daratumumab) and then have a prostatectomy (the surgical removal of the prostate) as part of their standard care. Biomarkers are found in the blood/tissue and may be related to your reaction to the study drug.
The objective of this study was to evaluate the safety profile of ELIGARD® in ethnic Asian prostate cancer patients.
The goal is to gain insight in the development and course of the toxicity after a curative treatment of prostate cancer
This is a multi-centre, double-blind, randomized phase III trial comparing metformin to placebo in patients with advanced prostate cancer starting (or have recently started) androgen deprivation therapy (ADT).
To investigate the effects of positive end-expiratory pressure (PEEP) on the intracerebral pressure (ICP) and intraocular pressure (IOP) in patients undergoing robot assisted laparoscopic radical prostatectomy (RALRP)
The main purpose of this study to determine the safety of an experimental medicine called 131I-MIP-1095. 131I-MIP-1095 is an investigational drug, meaning it has not been approved by the U.S. Food & Drug Administration (FDA).
