Filter by:Background: Prostate cancer is the second most common cancer and the fifth leading cause of death in men worldwide. Tumour growth is attributed to disproportionately greater protein synthesis rates relative to protein breakdown rates. Tumour protein synthesis is modulated by several factors, including energy availability, blood flow, and hormone concentrations (e.g., IGF-1). Lifestyle modifications are rapidly becoming recognized as important adjunct therapeutic approaches to slow cancer development and enhance treatment efficacy. Dietary energy restriction is a 30-50% reduction in food intake, which induces an energy deficit and has been shown to attenuate tumour growth in rodent models. Muscle mass often declines during cancer treatment and negatively impacts treatment success rates and recovery. One drawback to dietary energy restriction is that it may accelerate declines in skeletal muscle mass and strength in cancer patients. Exercise also induces an energy deficit by increasing energy expenditure. In addition, exercise alters blood flow and releases circulating molecules, which appear to lower tumour protein synthesis rates. Exercise increases muscle protein synthesis rates, which would provide further benefits to cancer patients by helping to maintain skeletal muscle mass. Despite their promising therapeutic properties, the clinical efficacy of dietary energy restriction and exercise has not been directly determined in vivo in cancer patients. Hypothesis and Objectives: The objective of this study is to compare the impact of dietary energy restriction versus (isocaloric) daily exercise on muscle, prostate, and prostate tumour protein synthesis rates over a 7-day period in vivo in prostate cancer patients. It is hypothesized that 1) dietary energy restriction will lower both prostate tumour and muscle tissue protein synthesis rates and that 2) daily exercise will lower prostate tumour protein synthesis rates but increase muscle protein synthesis rates in prostate cancer patients. Setting and Methods: Forty-five prostate cancer patients scheduled to undergo radical prostatectomy will be randomly assigned to one of three groups. The first group will undergo 7 days of dietary energy restriction (40% less food intake). The second group will perform 7 days of daily exercise and mild dietary energy restriction resulting in a total energy deficit of 40%. The third group will follow their regular diet and physical activity (control group). The research team will provide all aspects of the intervention (standardized meals, personalized exercise supervision). Patients will ingest deuterium-labelled water (2H2O) throughout the intervention period. After 7 days, patients will undergo a radical prostatectomy, during which tumour tissue, skeletal muscle tissue, and blood will be collected. Deuterium (2H-alanine) incorporation into the tissue samples will be measured to assess prostate tumour and skeletal muscle tissue protein synthesis rates.
This is a prospective randomized multicenter study aimed at comparing 3D AI-AR-RARP vs. no 3D, verifying the impact of this new technology on oncological and functional outcomes after the procedure.
The goal of this interventional non-inferiority trial is to assess the accuracy of different real-time motion management radiotherapy techniques. The main question the study aims to answer are: - What are the target margins for radiotherapy with motion management that are not inferior to target margin without motion management - What are the dosimetric and geometrical accuracy to patient for the motion management techniques. Participants will answer QoL questionary, and the accuracy of treatment will be assessed from treatment data.
The aim of this study is to look at whether an Artificial Intelligence (AI) based computer program can automate two components of the radiotherapy treatment pathway to a sufficient quality standard to enable its routine clinical use. The two components include the delineation (outlining) of anatomical areas that are at risk of tumour spread and at risk of radiation damage, and the definition of the position, size and shape of the radiation beams. The AI-based computer programs have been developed to perform tasks that would normally require direct human involvement by oncologists and medical physicists. Proposed advantages include improved treatment accuracy, as well as a reduction in the time (from weeks to minutes) and human resources needed to deliver radiotherapy, which this study will test.
Prostate Stereotactic ablative body radiotherapy (SABR) is an established technique that delivers radiation in a non-invasive approach for men with prostate cancer. The treatment regimen is given in total of 5 fractions with one treatment per day at every other day or weekly sessions. Ultra-hypofractionated radiotherapy (UHRT) is an emerging monotherapy for localized prostate cancer however, several trials have observed demonstrating superior biochemical control of a two-fraction (HDR) over single-fraction approach. The study aims to compare an experimental shorter course of prostate ultra-hypofractionated radiotherapy (UHRT) that will deliver what is expected to be an equivalent amount of radiation as given in the standard 5 treatment regimen. UHRT is given in 2 treatments with one treatment a week for 2 consecutive weeks.
Background: Prostate cancer is often treated with radiation and ADT (ADT is androgen deprivation therapy). Up to 30% of these cancers recur within 5 years of treatment. Researchers want to see if a new drug (M9241) can help the immune system to fight prostate cancer. Objective: To find what doses of M9241 are safe in people who are treated for prostate cancer. Also, to see what effects M9241 has on the immune system. Eligibility: People aged 18 and older with high- and intermediate-risk prostate cancer. Their cancer must not have spread to other parts of the body. Design: The study will last 7 months. Participants will be screened. They will share their medical history. They will also have: <TAB>A physical exam <TAB>Routine blood and urine tests <TAB>Imaging scans of the chest, abdomen, and pelvis <TAB>A bone scan <TAB>A tumor biopsy <TAB>A specialized MRI. Participants will lie face down on the MRI scanner table. An antenna that receives a signal may be placed in the rectum. All participants will be treated with radiation therapy and ADT. Some participants will also receive M9241 as an injection under the skin. This treatment will start 4 weeks after the radiation has ended. Participants will receive a total of 3 doses. The injections will be 4 weeks apart. Some screening tests will be repeated at each visit. Participants who do not receive M9241 will also have screening tests during the treatment period. Participants will return for follow-up about 1 month after the last treatment or set of tests.
NUV-868-01 is a first-in human, open- label, Phase 1/2 dose escalation and expansion study in patients with advanced solid tumors. The Phase 1 and 1b portions include patients with advanced solid tumors and are designed to determine the safety and the dose(s) of NUV-868 to be used as monotherapy and in combination with olaparib or enzalutamide for the Phase 2 portion. In Phase 2, NUV-868 in combination with olaparib or enzalutamide will be given to determine the safety and efficacy of these study treatments. One cohort of patients (with enzalutamide-naïve metastatic castration-resistant prostate cancer) will be randomized to receive either NUV-868 monotherapy, enzalutamide monotherapy, or the combination of NUV-868 + enzalutamide. Patients will self-administer NUV-868 orally daily in 28-day cycles as monotherapy in Phases 1 and 2. In Phases 1b and 2, patients will self-administer NUV-868 orally daily in 28-day cycles in combination with olaparib or enzalutamide daily at standard prescribed doses (Phase 1b) or at the recommended Phase 2 combination dose (RP2cD) that is determined in Phase 1b. Patients will be treated until disease progression, toxicity, withdrawal of consent, or termination of the study.
The objective of this study is to compare the short-term and 1-yr follow-up functional outcomes of retzius-repairing robot-assisted radical prostatectomy (RR-RARP) with retzius-sparing (RS) RARP. This study is a single-centre, single-surgeon and a prospective randomized study.
This randomized controlled trial (RCT) will aim to examine the effect of a 12-week behavioural intervention on changing the sedentary behaviours (SB) of prostate cancer survivors (PCS) compared to a control group (FitBit-only group). PCS in the intervention group will receive a FitBit and 6 behavioural support sessions with a movement specialist guided by behavioural theory (i.e., the Multi-Process Action Control [M-PAC]). The FitBit-only group will only receive a FitBit and access to public health resources on physical activity (PA). The primary purpose of this study is to determine the efficacy of the intervention on changing SB of PCS immediately following the 12-week intervention and 6-months later. It is hypothesized that that the intervention will decrease their SB compared to the FitBit-only control condition at both timepoints. This trial will also examine the effect of the intervention on changing PA, motivational outcomes from the M-PAC framework, sleep quality, social support, physical function, quality of life, fatigue, disability and mental health compared to the active control condition.
NUV-422-04 is an open-label Phase 1b/2 dose escalation and expansion study designed to evaluate the safety and efficacy of NUV-422 in combination with enzalutamide. The study population is comprised of adults with mCRPC. Patients will self-administer NUV-422 and 160 mg enzalutamide orally in 28-day cycles. Patients will be treated until disease progression, toxicity, withdrawal of consent, or termination of the study.
