A Phase 1, Open-label Study to Assess Safety, Biodistribution, and Internal Radiation Dosimetry of rhPSMA-7.3 (18F) Injection in Healthy Volunteers, and to Assess Safety and Investigate the Imaging Characteristics in Subjects With Prostate Cancer.
Prostate cancer (PCa) is among the most widespread in the male population and represents 20% of all cancers diagnosed from the age of fifty, in Italy. Androgen deprivation therapy (ADT) is a common strategy of treatment that is used for increase survival. However, ADT is associated with significant side effects, such as fatigue, loss of muscle mass and strength, cognitive decline and reduced quality of life, with an increased the risk for falls and fractures, cardiometabolic syndrome and cardiovascular events. The numerous side effects from ADT could potentially be countered by the regular Physical Exercise (PE), with favorable effects on body composition, physical performance, bone health and cognitive function. However, to maintain the results obtained, PE must be undertaken regularly, becoming a healthy habit of life. The patient motivation is therefore a fundamental element for guaranteeing adherence to the intervention and its integration into people's lifestyle. The study aim is to analyzed patients with PCa at the time of diagnosis regarding their lifestyle, includes regular PE, and motivation to make changes about their habits. In addition, the investigators will describe the perceived barriers by patients about this change. The data collected will allow the development of an experimental intervention of PE, associated with therapeutic education, and assess its impact on the health of patient undergoing ADT, considering the realistic possibilities of application in the daily life of these patients, testing its feasibility and safety, the compliance and the satisfaction of the patients.
Biomarker series can indicate disease progression and predict clinical endpoints. When a treatment is prescribed depending on the biomarker, confounding by indication might be introduced if the treatment modifies the marker profile and risk of failure. The two-stage model fitted within a Bayesian Markov Chain Monte Carlo framework is particularly flexible to account for such data. Prostate-specific antigens in prostate cancer patients treated with external beam radiation therapy can be monitored. In the presence of rising prostate-specific antigens after external beam radiation therapy, salvage hormone therapy can be prescribed to reduce both the prostate-specific antigens concentration and the risk of clinical failure, an illustration of confounding by indication. The prognostic value of hormone therapy and prostate-specific antigens trajectory on the risk of failure based on a two-stage model within a Bayesian framework to assess the role of the prostate-specific antigens profile on clinical failure while accounting for a secondary treatment prescribed by indication. the aim of this research is to model prostate specific antigens using a hierarchical piecewise linear trajectory with a random changepoint. Residual prostate-specific antigens variability can be expressed as a function of prostate-specific antigens concentration. Covariates in the survival model can include : hormone therapy, baseline characteristics, and individual predictions of the prostate-specific antigens nadir and timing and prostate-specific antigens slopes before and after the nadir as provided by the longitudinal process.

Rationale: This prospective study investigates the outcomes of daily online stereotactic MR-guided adaptive radiation therapy (SMART) in patients with localized prostate cancer (cT1c-T3bN0M0). Visualization of the prostate, rectum and bladder prior to and during radiation delivery can be used to deliver "gated" treatment (beam-on only when the prostate is in the predetermined position) using small uncertainty margins. The novel MRIdian treatment delivery system (ViewRay, USA), which will be used for this study, allows for the immediate generation of an optimal radiotherapy plan based on the current anatomy of the prostate and surrounding normal organs prior to each fraction. These major advances will (i.e. dosimetrically) allow for an optimisation of normal tissue radiation doses, which should theoretically decrease toxicity to surrounding organs such as the rectum or bladder. Another advantage of this approach is that online MR-based prostate imaging does not rely on implanted gold markers, avoiding an invasive procedure to insert such markers. If proven feasible, this approach could set a new standard of care for patients with localized prostate cancer. The main goal of this phase II study of SMART for prostate cancer is to evaluate the early and early-delayed toxicity, i.e. within the first year after treatment. An established 5-fraction hypofractionated radiation scheme will be used in this trial. Main outcome parameters will include gastro-intestinal, genitourinary and sexual symptoms, which will be monitored at fixed time points using CTCAE criteria. In addition, patient-reported outcomes will be evaluated using EORTC-QOL questionnaires. Objective: To investigate the early and early-delayed toxicity profile of SMART in patients with localized prostate cancer. Study design:phase II observational study Study population: 100 consecutive patients with localized prostate cancer (cT1c-T3bN0M0). Study intervention: Study patients will be treated with an online MR-guided hypofractionated course of radiotherapy in 5 fractions of 7.25 Gy per fraction delivered on the prostate with a simultaneous integrated sparing of the urethra with a dose of 32.5 Gy in 5 fractions Main study parameters: Early and early-delayed toxicity (CTCAE v. 4.0); (IPSS) and Qol C30 PR25. Secondary endpoint will be the offline evaluation of the dosimetric benefit of SMART by comparing cumulative doses to organs at risk.
The STHLM3-AS study will evaluate the specificity of a new proposed protocol for active surveillance using the Stockholm3 test in combination with MRI targeted biopsies for prostate cancer detection in men with diagnosed low-risk prostate cancer undergoing active surveillance in comparison to conventional follow up using PSA and systematic biopsies.
This study is being conducted to determine whether the combination of imaging agents 68-Ga RM2 and 68-Ga PMSA11 is better at assessing response to high intensity focused ultrasound (HIFU) or high dose rate (HDR) local therapy than standard imaging or biopsy in patients with known prostate cancer.
In recent decades, the cancer process has been linked to microbial infections, particularly in gastric and Helicobacter pylori cancers, but also in cervical cancers promoted by exposure to Human papilloma virus (HPV). More recently, it has been shown that bacteria in the intestinal microbiota could promote the development of colorectal cancer by modulating the inflammatory response within the intestinal mucosa. Among male cancers, prostate cancer is the leading cause in France with 54,000 new cases per year. In addition, the dogma that urine is sterile has been broken and the notion of the presence of a "urinary microbiota" in asymptomatic patients is now accepted. While the risk factors associated with this cancer have not yet been clearly elucidated, recent evidence in the literature agrees that chronic inflammation associated with prostate infection plays a key role as a factor that may promote the development and/or progression of prostate cancer. Most recently, a study shows for the first time that a group of 6 bacteria is found significantly higher in the urine of patients with prostate cancer than in patients with prostate adenoma. Interestingly, clinical microbiology studies conducted at the bacteriology laboratory of the University Hospital of Nice on A. schaalii have shown that this species is also isolated in the urine of patients with bladder and prostate cancers. The investigators wish to study the association of the 6 bacterial species mentioned above with prostate cancer by directly analyzing the prostate tissue of patients with this condition. the staff will carry out a multicenter case-control study by recruiting a total of 260 patients in 4 centres (Nice coordinating centre, Marseille, Tours and Nîmes): 130 in the prostate cancer group and 130 in the prostate adenoma control group. This project is a research involving the human person of category 2. The innovative aspect of the work consists in detecting and quantifying in situ in the prostate tissue the presence of these 6 bacterial species per culture and per PCR in real time, comparing the prostate microbiota in terms of richness and diversity between cancer patients and those without cancer. Ultimately, this study opens up exciting prospects with the possibility of determining a microbial origin of prostate cancer and considering antibiotic therapy for anti-cancer purposes such as H. pylori and gastric cancer.
