Filter by:This randomized phase II/III trial studies docetaxel, antiandrogen therapy, and radiation therapy to see how well it works compared with antiandrogen therapy and radiation therapy alone in treating patients with prostate cancer that has been removed by surgery. Androgen can cause the growth of prostate cells. Antihormone therapy may lessen the amount of androgen made by the body. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving antiandrogen therapy and radiation therapy with or without docetaxel after surgery may kill any remaining tumor cells.
The purpose of this study is to look at patient outcomes when docetaxel is started prior to ADT with degarelix.
Study of Biweekly Docetaxel plus Androgen-Deprivation Therapy (ADT) in Patients with Previously-Untreated, Metastatic, Prostatic Adenocarcinoma
The primary objective is to test the following hypothesis: Patients with metastatic castrate resistant prostate cancer that have progressed following at least one line of therapy and have an immunogenic signature will respond to combined PD-1 and CTLA4 inhibition.
After failure on docetaxel, which has been the standard first line therapy for patients with metastatic castration-resistant prostate cancer (mCRPC), several treatment options are currently available. In retrospective studies, resistance has been described to two of the treatment options, enzalutamide and abiraterone, when a splice variant of the Androgen Receptor (AR-V7) is present on circulating tumor cells (CTCs). The investigators hypothesize that patients with AR-V7 positive CTCs do have a meaningful response to cabazitaxel.
Olaparib has demonstrated preliminary efficacy in metastatic castration-resistant prostate cancer. In a trial of 49 evaluable patients treated with olaparib, 11 / 49 experienced a PSA response, and every patient with a radiographic response also had a PSA5 response. Ten of 11 responders had mutations in DNA repair genes. While PARP inhibition is showing promise in these initial studies, reserving its use for end-stage patients may not be the optimal timing for olaparib therapy in some patients. In addition, PARP enzymes function in roles beyond DNA repair, and specifically for prostate cancer are involved transcriptional regulation of the androgen receptor. PARP inhibition has not been tested in earlier disease states for prostate cancer.
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.
This clinical trial studies how well a long-term follow-up works in patients with prostate cancer after surgery. Long-term follow-up data may serve as a resource to help ask clinical questions, describe health-related quality of life and long-term complications related, and facilitate future studies focusing on interventions to improve health status and health-related quality of life in prostate cancer survivors.
The aim of this study was to determine the efficacy and safety of the implementation of a program of " image-guided focal Intensification dose to intraprostatic dominant lesion " in men with localized prostate cancer (PCa) of intermediate and high risk (criteria NCCN) eligible to receive radiotherapy in the Department of Radiation Oncology of HUP (Hospital Universitario de La Princesa), within the established dose escalation protocol with intensity modulated image-guided radiotherapy (IMRT / IGRT).
