NCT02989857
Study AG120-C-005 is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study of orally administered AG-120. Participants, all personnel involved in the evaluation of participants' response to treatment (e.g., Investigators, study coordinators, study pharmacists), and designated Sponsor team members will be blinded to study treatment. Participants are required to have a histologically-confirmed diagnosis of isocitrate dehydrogenase-1 (IDH1) gene-mutated cholangiocarcinoma that is not eligible for curative resection, transplantation, or ablative therapies prior to enrollment. IDH1 mutation testing will be performed at participating investigative sites. Participants must have progression of disease and have received at least 1 but not more than 2 prior treatment regimens for advanced disease (nonresectable or metastatic). All participants must have received either a gemcitabine or a 5 fluorouracil (5-FU) based chemotherapy regimen.

NCT04901624
Repeat testing for SARS-CoV-2 antibodies in disadvantaged communities will help identify active and recovered infections over time, and as more is understood about antibody protection, it may help identify persons who have immunity. Many questions about social barriers and behavioral facilitators remain unanswered. This project aims to evaluate the effectiveness of risk-based messaging and incentives that promote repeated testing for SARS-CoV-2 antibodies, as well as to understand social and behavioral determinants of COVID-19 testing and variations within sub-groups of this population.

NCT05629715
Knee osteoarthritis is a debilitating disease that can cause severe knee pain and significant limitations to patients' activities of daily living. Total knee arthroplasty (TKA), also known as knee replacement surgery, is a well-established and successful procedure for treatment of end-stage knee osteoarthritis. Over the years, TKA surgical techniques and implant technology have improved, resulting in better patient outcomes and implant survivorship. Despite continuous improvements being made to this high demand procedure, malalignment of component position is a well-known cause of post-operative complications, including knee pain, component loosening, and failure requiring revision surgery. Advanced techniques that utilize computer navigation or robotic-arm assistance have been developed in an attempt to avoid malalignment. Both technologies were created with the goal of improving the precision of implant positioning and implant sizing in order to improve lower limb alignment and joint line alignment. The OrthoAlign KneeAlign computer assisted navigation system is a commercially available device that uses gyroscopic limb position sensing technology mounted to intramedullary and extramedullary jigs to measure bone resection cuts in TKA that ultimately dictate implant position. The Zimmer Biomet ROSA Knee System is a commercially available, FDA-approved robotic assistant for performing TKA. It uses pre-operative x-rays to create a three-dimensional image of the patient's knee anatomy, which is used to create a pre-operative template of the implants to be used and provides intra-operative guidance for bone cuts during the TKA. The robotic system also assesses the soft tissue envelope around the knee and can assist with the soft tissue balancing of the knee arthroplasty. Alternatively, it can also be used in an imageless mode where bone cuts are performed based on intra-operative mapping using anatomic landmarks. To date, there have been no prospective studies comparing the implant positioning and patient outcomes directly of the KneeAlign system with the ROSA system and conventional TKA instrumentation techniques.

Soluble and imaging biomarkers will be investigated addressing different aspects of disease pathways postulated to be relevant for COPD progression.
NCT05151172
Stroke occurs when a blood clot causes a blockage in a blood vessel (artery) within the brain. This type of stroke is called an ischemic stroke and carries a high risk of disability or death. Stroke must be treated very fast. Any delay of even 10 minutes can result in the difference between an independent and a disabled outcome, and in some cases between life and death. Endovascular therapy (EVT) or Thrombectomy is a procedure to remove the blood clot (thrombus) from a blood vessel to reopen it (recanalization). Patients are likely to benefit from a thrombectomy procedure when it is performed in a larger blood vessel. Currently it is not known if thrombectomy procedure will benefit the patients presenting with the stroke that has been caused by a blood clot in a medium sized blood vessel (medium vessel occlusion, MeVO). This trial will enrol patients diagnosed with acute stroke due to a clot in the medium sized vessel. The patients will be randomized within 12 hours of their symptom onset to either standard of care or standard of care plus thrombectomy procedure. The participation will last for 12 months Escape MeVO coordinating centre is located at the University of Calgary. There will be up to 75 sites. We will be recruiting a total of 530 patients.

NCT06549088
This study investigates if a new imaging device can detect different types of lung tissue using spatial frequency domain imaging (SFDI). Specifically, this study aims to detect lung nodules within normal lung tissue and determine if lung nodules are cancerous. Patients who have confirmed or suspected lung nodules and who are undergoing resection of those nodules will be recruited for the study. Study participants will undergo standard of care lung nodule resection in the operating room, and the resected specimen will be imaged using the SFDI device immediately after removal from the surgical field. The data captured from the SFDI images will then be compared to the pathology findings to identify optical properties of normal and cancerous lung tissue. Because the intervention is conducted on resected biospecimens, this study yields minimal risk to participants.
