A Phase II Study of Fluorine-18 (18F)-Labeled PSMA-1007 in Patients With Known or Suspected Metastatic Prostatic Carcinoma
A [18]F-PSMA-1007 PET/CT or PET/MRI scan are nuclear medicine tests used to create pictures of the whole body that may show where cells that express Prostate-Specific Membrane Antigen (PSMA) are found. PSMA is a transmembrane protein that is overexpressed in the majority of prostate cancers. PSMA imaging utilizes this overexpression, by binding on the transmembrane receptor and internalization in the cancer cells. The internalized isotope can then be imaged with the use of a PET/CT or PET/MRI scanner and show where cancer cells may be present in the body. This imaging modality has been shown to be superior to conventional imaging, such as bone scan and CT, in the detection of prostate cancer tumors. The purpose of this study is to: 1) assess the clinical impact of a [18]F-PSMA-1007 scan on patient management plans; 2) assess the diagnostic effectiveness of a [18]F-PSMA-1007 scan in participants with known or suspected metastatic prostate cancer, as compared to standard of care CT chest, abdomen, pelvis and bone scan; 3) evaluate the safety of [18]F-PSMA-1007; and 4) assess potential correlations of PSMA level of uptake in certain tumors with cancer biologic markers such as PSA and Gleason score.

Safety and Efficacy Study of Neoadjuvant Radiohormonal Therapy for Oligometastatic Prostate Cancer: a Multi-center Randomized Controlled Clinical Trial
The optimal treatment for oligometastatic prostate cancer (OMPC) is still on its way. Accumulating evidence has proven the safety and feasibility of radical prostatectomy and local or metastasis-directed radiotherapy for oligometastatic patients. The aim of this trial is to compare the safety and feasibility outcomes of metastasis-directed neoadjuvant radiotherapy (naRT) and neoadjuvant androgen deprivation therapy (naADT) followed by robotic-assisted radical prostatectomy (RARP) to ADT combined with abiraterone for treating OMPC.

Standard Moderately Hypofractionated Radiotherapy vs. Ultra-hypofractionated Focal Lesion Ablative Microboost in Prostate Cancer, Hypo-FLAME 3.0
EBRT is one of the standard treatment options for patients with localized PCA. Based on the outcome of randomized trials, moderately hypofractionated RT(19-25 fractions of 2.5-3.4Gy) is considered equivalent to conventional fractionated schemes with 35-39 fractions of 2Gy. A schedule of 20 fractions to a dose of 60-62Gy is adopted as standard of care for all risk-groups. Driven by the success of moderate hypofractionation, there is a strong trend towards extreme hypofractionation, also called SBRT, reducing the number of fractions even further. The schedule mostly used is 5 fractions of 7-7.25Gy. Its effectiveness, equivalence to standard EBRT schedules, has been demonstrated for low and favourable intermediate risk (IM) patients. For unfavourable IM (here defined as IM with ISUP grade 3) and high-risk (HR) PCA the outcome of EBRT can be further improved by dose escalation. Because of dose-limiting toxicity, the maximal dose of EBRT for conventionally fractionated schemes was approximately 80Gy. Initially hypofractionation was considered as a potential way to escalate the biologically effective dose (BED) above 80Gy, however, this proved not to be the case. With hypofractionation, a saturation in dose effect seems to be present at a BED of 80Gy. Recently, the multi-centre phase III FLAME trial broke the '80Gy barrier' and showed that in mainly HR PCA patients, treated with a conventional fractionation schedule, focal boosting of the intraprostatic lesion to a total dose of 95Gy improves biochemical disease-free survival (bDFS). However, given the advantages of hypofractionation in terms of patient comfort and costs, the FLAME schedule is not ideal as the standard treatment. For unfavourable IM and HR PCA patients the value of SBRT has not yet been established. The FLAME trial showed that higher than standard BED is a prerequisite for optimal bDFS. Furthermore, post SBRT biopsies results suggest a dose response relationship with better outcome of dose levels above 40Gy. Therefore, probably a higher than standard dose SBRT is necessary for these patients. A recent meta-analysis suggests diminishing results from increased fraction sizes in SBRT. So, the question remains whether dose escalation in SBRT will indeed improve treatment outcome. With standard SBRT to the whole prostate, dose escalation is limited to 40Gy because of unacceptable toxicity. In line with FLAME, we conducted the Hypo-FLAME trial investigating focal dose escalation in SBRT. In the phase II Hypo-FLAME trial, 100 patients with IM or HR PCA were treated with SBRT 35Gy in 5 weekly fractions to the whole prostate with a focal boost up to 50Gy. The acute toxicity rates, the primary endpoint, were low and similar to standard SBRT indicating this schedule can be safely applied. Given this was a phase II trial, no conclusions on oncological outcome can be drawn. Shortening of the overall treatment time (OTT) has been suggested to play a role in SBRT efficacy and 5 fractions delivered every other day this is internationally accepted as standard. We therefore initiated the phase II Hypo-FLAME 2.0 trial, investigating the feasibility of a reduction in the OTT of the Hypo-FLAME schedule from 29 to 15 days with acute toxicity as primary endpoint. The accrual of this trial is completed and a first analysis of the primary endpoint shows low toxicity figures, well in the range of what was expected. We expect to submit the analysis for publication by the end of 2022. At present, it is unknown what the oncological efficacy of the Hypo-FLAME schedule is compared to the standard of care in unfavourable IM and HR prostate cancer. Therefore, we will conduct a Phase III multi-centre randomized trial, in which 484 patients with unfavourable IM or HR PCA will be randomized between: 1. Standard treatment; moderately hypofractionated radiotherapy 62 Gy in 20 fractions of 3.1Gy 2. Experimental treatment; SBRT 5x7Gy with an iso-toxic integrated focal boost up to 50 Gy (Hypo-FLAME).

TRANBERG® Transperineal MR/US Focalyx Fusion Laser--Induced Thermal Therapy in the Office Setting Under Local Anesthesia
This study is set up as a phase I prospective, single center, device interventional pilot study carried in office setting under local anesthesia. It will assess the tolerance and safety of target fusion ablation of prostate cancer tumors using Laser Induced Thermal Therapy (TFA-LITT) guided by fusion imaging in men 50 to 80 years of age with low to intermediate risk prostate cancer Prostate Cancer is currently managed with in a discrete fashion where patients either enroll in active surveillance protocols (No intervention) or undergo full intervention via whole gland treatments - most commonly radical surgery or radiation. These treatments have not shown definitive gains in all cause survival and not uncommonly harbor undesirable adverse effects, most notably: impotency and incontinence. Such events elicit significant and noticeable changes on a male lifestyle and for most prostate cancer tumors are considered overtreatment. This study aims to evaluate the use of TFA-LITT in the office setting under local anesthesia - greatly decreasing patient perioperative surgical risk - focused on the organ sparing cancer lesion ablation, where organ function is preserved. The fundamental objective is to determine the tolerance and safety of TFA-LITT in men with low to intermediate risk prostate cancer, successful performed in the outpatient office-based setting under local anesthesia directed by fusion imaging. Secondary objectives include: 1-Biopsy proven cancer control of ablated areas 12 months after procedure; 2-Uroflowmetry and urinary function Patient Reported Outcome Measures (PROMs) at one, three, six, nine and 12 months; 3- Sexual function Patient Reported Outcome Measures (PROMs) at one, three, six, nine and 12 months; 4- MRI changes of ablated area one, three and 12 months after TFA-LITT; 5- Absence or presence of ejaculation after TFA-LITT.

A Phase II Study of Lutetium Lu 177 Dotatate in Metastatic Prostate Cancer With Neuroendocrine Differentiation
This phase II trial studies how well lutetium Lu 177 dotatate works in treating patients with prostate cancer with neuroendocrine differentiation that has spread to other places in the body (metastatic). Neuroendocrine differentiation refers to cells that have traits of both hormone-producing endocrine cells and nerve cells. These cells release hormones into the blood in response to a signal from the nervous system. Hormones are biological substances that circulate through the bloodstream to control the activity of other organs or cells in the body. Lutetium Lu 177-dotate is a radioactive drug. It binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Lutetium Lu 177-dotatate builds up in these cells and gives off radiation that may kill them. It is a type of radioconjugate and a type of somatostatin analog. Treatment with Lutetium Lu 177 dotatate may shrink the tumor in a way that can be measured in patients with metastatic prostate cancer with neuroendocrine differentiation.
