It is a phase I study of radical hypofractionation delivering one single fraction of SBRT in patients with low- and favorable intermediate-risk prostate cancer that will undergo placement of the SpaceOAR hydrogel prior to treatment. Our hypothesis is that treatments can be safely delivered in one single fraction using SBRT provided the separation between the prostate and rectum is increased using the hydrogel Read Less

Prostate cancer is the second most common cancer among Canadian men of which approximately 20-30% present with high-risk tumour characteristic. Although surgery can be curative in patients evidencing pathological high-risk disease (extracapsular extension, seminal vesicle involvement, positive surgical margins), a large proportion will develop biochemical failure within years from the surgical procedure. The failure rate is even more pronounced in those patients that present with high prostate specific antigen (PSA) levels, pT3 disease, positive margins and Gleason score ≥8 with an estimated 75% failure rate at 10 years. Post-operative radiotherapy (RT) has been shown in three randomized trials to significantly decrease the biochemical failure rate and in one of the trials a survival benefit was also seen with the addition of post-operative RT and is considered by many investigators standard therapy in patients with pathological high-risks factors even in absence of biochemical failure.

This study is investigating a new technique for delivering chemotherapy directly into the lungs at the time of surgery. Delivering chemotherapy directly to the lungs could potentially kill any microscopic cancer cells that are present in the lungs at the time of surgery, while sparing other major organs in the body from the side effects of chemotherapy. This technique is called In Vivo Lung Perfusion (IVLP). At the University Health Network, this IVLP technique has been used recently in a Phase I study in patients with sarcoma, and we are now expanding on that experience to include patients with colorectal metastases. The purpose of this study is to test the safety of the IVLP technique and find the dose that seems right in humans. Participants are given oxaliplatin into one lung via IVLP and are watched very closely to see what side effects they have and to make sure the side effects are not severe. If the side effects are not severe, then more participants are asked to join the study and are given a higher dose of oxaliplatin. Participants joining the study later on will get higher doses of oxaliplatin than participants who join earlier. This will continue until a dose is found that causes severe but temporary side effects. Doses higher than that will not be given. The other lung will not be infused with anything, so that we can limit unforeseen toxicity to a single lung and see if one lung does better than the other. Read Less

The goal of this study is to assess the safety and tolerability of GSK5733584. The study will also see how the levels of GSK5733584 change over time at different dose amount. Read Less

The goal of this clinical trial is to investigate the safety and efficacy of Irreversible Electroporation (IRE) using NanoKnife technology in patients with intermediate-risk prostate cancer. This patient population was chosen because they would otherwise be treated with conventional therapies with high side effects. The main questions it aims to answer are: 1. Is the NanoKnife system is effective at damaging prostate tumour cells, and killing the cancer? 2. Are there any safety concerns with the procedure, or major side effects caused by the treatment? Participants will undergo IRE treatment with the NanoKnife system, and then complete follow-up appointments for 12-months after the procedure. Read Less

Advanced hormone positive (HR+), HER2 negative breast cancer continues to pose a challenge when patients have progressed on CDK4/6 inhibitor and endocrine therapy leaving limited treatment options. Antibody-drug conjugates (ADCs) such as sacituzumab govitecan (SG) and trastuzumab deruxtecan (T-DXd) have changed practice due to significant improvement in progression free survival (PFS) and overall survival (OS) seen in this disease setting. There is a genuine interest to use SG sequentially after T-DXd, however there is no current prospectively curated evidence to support this strategy. Though the epitope is different, the payload are both topoisomerase I inhibitors. Thus, evidence is needed of both clinical efficacy and identification of mechanisms of sensitivity and resistance to sequential ADCs in HER-2 low MBC. It is hypothesized that performing whole genome and whole transcriptome sequencing in fresh tumour biopsies post progression of T-DXd and prior to SG in ER+/HER2 low metastatic breast cancer (MBC) will provide mechanistic insights into identifying biomarkers, and thus patients, sensitive to sequential SG.

This is a phase ll study of participants with large B Cell lymphoma previously treated with anti-CD19 Chimeric antigen receptor (CAR-T) therapy. The purpose of the study is to to evaluate the efficacy of zanubrutinib and tislelizumab in patients with progressive lymphoma post anti-CD 19 CAR-T failure. Read Less

Pasteurized Donor Human Milk (PDHM) is recognized as providing vital immunological and nutritional benefits to vulnerable infants. Although PDHM is widely used in neonatal intensive care units (NICUs) to prevent infections (necrotizing enterocolitis) and improve infant health outcomes, its use for other populations, such as HIV-exposed infants, has been minimal. Pasteurized donor human milk is included in the 2023 Canadian Paediatric Society clinical consensus as a potential way to provide HIV-exposed infants some of the immunological benefits of human milk in a safe manner, as opposed to exclusive formula feeding (which is currently considered the gold standard for HIV-exposed infants). These new consensus guidelines also include recommendations to support those who wish to breastfeed using a harm reduction approach (e.g., increased viral load monitoring by peds infectious diseases), given the low risk of transmission in those adhering to antiretroviral medications. However, mixed feeding (e.g., breastfeeding and provision of infant formula) is not recommended, due to the potential for micro abrasions in the gastrointestinal epithelium as a result of the protein size in infant formula (which is larger and more abrasive than in human milk), which may increase the risk of HIV transmission if the HIV virus is present in breastmilk. As such, donor milk also presents a possible solution to support those who choose to breastfeed, but who may require a temporary supplement for whatever reason (e.g., nipple cracks, mastitis, etc.), as donor milk is human milk, thus has the same size of proteins and does not pose the same risk as infant formula in damaging the epithelial layer in the gut. Overall, major obstacles remain that prevent newborns outside of the NICU from regularly having access to donor human milk. These obstacles are illustrated by the high cost of donor milk, which is not covered by government programs, and the lack of information about the clinical benefits (for both those who choose to breastfeed or formula feed), acceptability of caregivers for this feeding option, and feasibility of providing donor human milk outside of a hospital setting. The investigators aim to determine whether giving PDHM to infants exposed to HIV is a practical possibility and learn from caregivers about any challenges associated with this feeding option. The results of this study will guide future research and a potential provincial initiative to expand access to PDHM for this population. Read Less

This trial collects clinical data and blood samples to predict the quality of response to specific treatments in patients with chronic graft-versus-host disease (cGVHD) who are about to start a new therapy. Collecting and analyzing clinical data and blood samples from patients with cGVHD before and after treatment initiation may help doctors identify changes that may predict treatment response. Read Less
