This study compares two arms - the current standard of care catheter ablation for Ventricular Tachycardia compared to stereotactic radiotherapy to non-invasively ablate ventricular tachycardia using a novel non-invasive ECG based body surface mapping technology. This allows investigators to identify ventricular tachycardia circuits to target for subsequent radio ablation. To summarize, the current standard of care invasive catheter ablation to the non-invasive radio ablation.

The aim of this study is to assess the feasibility of deep brain stimulation for refractory trigeminal neuralgia due to a pontine lesion, as is usually seen in the context of multiple sclerosis. These patients usually have severe intractable facial pain and current medical and surgical options generally fail to achieve long lasting pain relief. Hoping to improve pain control in this population, the investigators of this trial propose a novel technique consisting of implanting a deep brain stimulation lead within the pontine lesion to modulate the generation of pain signals.

Allergic rhinitis (AR) currently affects \~25% of Canadians, and due to factors of climate change, this number is expected to increase over the coming decade. AR symptoms can significantly impact individuals' quality of life by compromising sleep, productivity, and social interactions. To alleviate AR symptoms, North Americans tend to rely on H1 antihistamine medications available over-the-counter (OTC) at most pharmacies. However, public health authorities currently suggest restraining all antihistamines during heat waves due to beliefs that M3 muscarinic receptor and H1 receptor antagonism, independent pharmacological mechanisms of H1 antihistamines, might suppress thermoregulatory responses to heat stress and increase individuals' susceptibility to heat-related illness/injury. To date, studies using supramaximal doses of antihistamines have demonstrated reductions in sweating, however these doses and administration routes are not the typical use case. Additional studies utilizing fexofenadine, a second-generation H1 antihistamine, have linked H1 receptor antagonism to reductions in skin blood flow, potentially impacting thermoregulation by reducing peripheral blood redistribution. Empirical evidence supporting OTC H1 antihistamines impacting thermoregulatory control at recommended doses is scarce. Thus, this study aims to systematically assess whether three common OTC H1 antihistamines, taken as prescribed, alter thermoregulatory responses during thermal stress.

The current standard for biopsy-based diagnoses of dysfunction of kidney transplants is the Banff Classification which represents arbitrary international consensus. Recent data-driven approaches using molecular and conventional technologies indicate that mere consensus produces frequently incorrect diagnoses with potential harm to patients due to inappropriate treatment. To address this unmet need and improve diagnostics in the area of organ transplantation, the Alberta Transplant Applied Genomics Centre (ATAGC) has developed a new diagnostic system that combines the molecular and histopathological features of transplant biopsies, plus clinical and laboratory parameters, to create the first Integrated Diagnostic System. The present study will validate and refine this system in 500 prospectively unselected biopsies for clinical indications from American, Canadian and European centres in addition to 300 biopsies already collected. Due to a considerable interest and support from participating Centers, the study is further extended to 1500 prospective biopsies. Thus this is the extension of the INTERCOM study (INTERCOMEX). In addition to demonstrating the feasibility and value of this System in routine patient care and clinical trials, the study will develop and optimize a transparent and user-friendly reporting format to communicate this information to clinicians and obtain detailed feedback on how this system can best improve patient care.

Phase 1/2, dose escalation and expansion study designed to evaluate the safety and tolerability of NVL-655, determine the recommended phase 2 dose (RP2D), and evaluate the antitumor activity in patients with advanced ALK- positive (ALK+) NSCLC and other solid tumors. Phase 1 will evaluate the overall safety and tolerability of NVL-655 and will determine the RP2D and, if applicable, the MTD of NVL-655 in patients with advanced ALK+ solid tumors. Phase 2 will determine the objective response rate (ORR) as assessed by Blinded Independent Central Review (BICR) of NVL-655 at the RP2D. Secondary objectives will include the duration of response (DOR), time to response (TTR), progression-free survival (PFS), overall survival (OS), and clinical benefit rate (CBR) of NVL-655 in patients with advanced ALK-positive NSCLC and other solid tumors.

The purpose of this Registry is to prospectively collect data of Recurrent Pregnancy Loss (RPL) patients attending the specialized care centre at the BC Women's Hospital, in order to evaluate investigation practices, treatment options, and outcomes for this patient population over time.

A Phase 2/3 study to investigate the efficacy and safety of luveltamab tazevibulin versus IC chemotherapy in women with ovarian cancer (including fallopian tube or primary peritoneal cancers) expressing FOLR1.

The exploratory ELIOS study aims to assess the value of novel investigational Eye Movement Biomarkers (EMBs) in tracking disease-related changes among a real-world cohort of Canadian patients with active RRMS, within the context of disease-modifying treatment (i.e., ofatumumab). To that end, the study will use the patented investigational, Eye Tracking Neurological Assessment (ETNA-ProgMS) SaMD (v1.0.11 or later), which has not yet received Health Canada approval, to reliably and accurately track eye movements with precision.

Individuals living with a psychotic disorder often experience changes to their thinking and social skills that can lead to challenges with work, school, relationships and living independently. One intervention to target these areas is cognitive remediation therapy, which can be delivered in virtual reality to help apply the skills and strategies learned to day-to-day life. Over the past few years, our team has co-developed a cognitive remediation program in virtual reality with healthcare professionals and people with lived experiences of psychosis. The current trial tests the feasibility and efficacy of this cognitive remediation program in virtual reality at improving thinking skills, social skills, and daily life functioning.

A strategy to target the oncogenic receptor HER2 using a version of the anti-HER2 therapeutic antibody trastuzumab coupled to desferrioxamine (DFO) and radiolabeled with zirconium-89 (\[89Zr\]-DFO-trastuzumab) has been successfully evaluated in our group in preclinical settings. Clinical studies by other groups in recent years have shown the potential of targeting HER2+ lesions with \[89Zr\]-DFO-trastuzumab in patients with HER2+ cancers. We now want to establish the diagnostic potential of a protocol adding \[89Zr\]-DFO-trastuzumab PET imaging to FDG PET already used in the clinic for the detection of HER2-expressing cancers, including low expression levels considered until now as HER2-negative (HER2-low, IHC score 1+ and 2+ without FISH amplification of the HER2 locus). The HER2-low status has recently gained relevance thanks to large studies showing the efficacy of immunotherapy combined with drugs such as Enhertu (trastuzumab-deruxtecan), while trastuzumab alone was traditionally only effective for HER2+ cancers (IHC score 2+/FISH+, or 3+). In particular, we aim to develop a method to assess whole-body intertumoral heterogeneity in HER2 expression in order to detect cases with heterogeneous diseases and thus better stage patients and guide the optimal choice of personalized and targeted treatment to use. More specifically, the project aims to image with \[89Zr\]-DFO-trastuzumab PET patients with cancer, particularly breast cancer, but also esophageal, gastric, ovarian, endometrial and lung cancer, and whose primary tumor status is HER2-low.
