This study evaluates the use of NanoPac injected directly into the prostate lesion in men with prostate cancer.
This is a prospective, randomized, open-label, phase II trial of cabozantinib in subjects with untreated, high risk prostate cancer undergoing radical prostatectomy. This multicenter study will enroll 30 subjects. Duke is the lead site for this trial. There will be a second site selected TBD. Patients will be assigned (first 9 subjects only) or randomized 2:1 to either: (1) cabozantinib 40 mg by mouth daily for 4 weeks, followed by a 2 week drug washout period before prostatectomy (n = 20), or (2) immediate prostatectomy within 12 weeks of registration (n = 10). The first 9 subjects (6 subjects assigned to cabozantinib treatment, 3 subjects assigned to immediate prostatectomy) will constitute the Safety Lead-In Cohort, which will be only accrued at Duke. After six subjects have received cabozantinib and completed the 57-85 day safety visit without triggering a stopping rule, subjects may be accrued at the ex-Duke site. The primary goal is to compare pathologic apoptotic indices (cleaved caspase-3) in prostatectomy specimens from patients who undergo immediate prostatectomy (controls) versus those who receive with cabozantinib followed by prostatectomy. The secondary objective is to conduct immune phenotypic profiling on the peripheral blood and tumor microenvironment in prostatectomy specimens from both groups. A statistical analysis will be used to compare the apoptotic indices between the two groups.
Primary Objective: The primary objective of this study is to assess the efficacy of 18F-DCFPyL PET-CT for initial staging of prostate cancer in Veterans compared to conventional imaging (99mTc-MDP bone scan and Diagnostic CT or MRI). The primary clinical endpoint of our study is the percent of Veterans with prostate cancer in which the 18F-DCFPyL PET-CT identifies M1 disease at initial staging. Secondary Objectives: Frequency of the change in primary treatment plan after initial staging.
Reduction of dose to or 'sparing' of neurovascular structures during stereotactic ablative body radiotherapy (SAbR) for localized prostate cancer will improve retention of sexual potency, while retaining excellent oncologic control and other secondary health-related quality of life (HRQOL) endpoints. Primary Objectives: • To compare the decline in patient health-related quality of life (HRQOL) instrument-defined erectile dysfunction following stereotactic ablative body radiotherapy (SAbR) with or without neurovascular sparing Secondary Objectives: - Assess acute (within 3 months of treatment) and chronic (>3 months after treatment) SAbR related GU and GI toxicities, as well as serial impact on HRQOL metrics over time - Assess biochemical progression free survival, local recurrence, distant recurrence, and survival - Evaluate simplified 'practical' secondary HRQOL sexual potency endpoints that can be compared to prior literature. Exploratory Objectives: - Evaluate feasibility of MRI BOLD/TOLD to be integrated as hypoxia monitoring sequences to standard already planned diagnostic and/or treatment planning MRI on the study in five patient pilot. - Evaluate quality of spacer placement and its effect on dose to neurovascular structures - Evaluate rate local recurrence in the area of sparing adjacent to the neurovascular elements by biopsy in those with biochemical progression.
The present phase I trial evaluates the feasibility of a postoperative stereotactic hypofractionated external beam radiation therapy delivered in patients who underwent radical prostatectomy with adverse pathological features or early biochemical failure. Modern computer-driven technology enables the implementation of ultra-high hypofractionated Image-Guided Radiotherapy (IGRT) safely. Eligible patients for this study are those with: - Adenocarcinoma of the prostate treated with radical prostatectomy (any type of radical prostatectomy is permitted including retropubic, perineal, laparoscopic or robotically assisted; there is no time limit for the date of radical prostatectomy) - Pathologic (p)T3 disease, positive margin(s), Gleason score 8-10, or seminal vesicle involvement - Undetectable post-radical prostatectomy PSA that becomes detectable and then increases on 2 subsequent measurements (PSA of > 0.1 - ≤ 2.0 ng/mL) - Life expectancy: 10 years - ECOG performance status of 0 -1 - No distant metastases, based on the following workup within 60 days prior to registration - Magnetic resonance imaging (MRI) of the pelvis - PSMA/Choline Positron Emission Tomography (PET) to exclude systemic disease in patients with biochemical recurrence - Patients can be on androgen deprivation therapy - Ability to understand and willingness to sign a study-specific informed consent prior to study. Patients enrolled in the study will undergo image-guided, volumetric intensity-modulated arc radiotherapy (IGRT-VMAT) with state-of-the-art treatment-planning and quality assurance procedures with emphasis on normal tissue sparing and delivery accuracy via the use of devices that ensure stability and beam location reproducibility.
The hypo-FLAME study is a multicenter phase II study (n=100) to investigate whether a focal SBRT boost to the MRI-defined macroscopic tumor volume is feasible and associated with acceptable toxicity in addition to whole gland prostate SBRT.
Adrenal androgens are serum biomarkers of interest that may help guide abiraterone acetate treatment, particularly at the time of progression. Biomarkers may also help identify pathways to resistance of abiraterone acetate treatment. The most practical way of approaching this question is to explore surrogate biomarkers of prostate cancer including quantification of pharmacodynamic endocrine biomarkers.
