Follow-Up Study of Subjects Previously Enrolled in Poxviral Vector Gene Transfer Studies
This study aims to provide long-term follow-up care of patients previously enrolled in a vaccine study that involved poxviral vectors. Vectors are sequences of genetic material that can be used to introduce specific genes into genetic makeup. The study does not involve the use of any drug or biologic agent. …
Collection of Blood From Patients With Cancer
This study will collect blood from patients with cancer to study the level of cells which decrease the immune response (suppressor cells) before and after chemotherapy. Patients 18 years of age and older with cancer may participate. This study does not involve treatment. Participants will have about 50 ml (3 …
Analyzing and Solving Exceptional Long-term Survivors in Solid Tumors With Poor Prognosis
This is a retrospective, exploratory, multi-center, translational, 3 cohorts case control matched study conducted in patients harboring a solid tumor with poor prognosis who presented a long-term (case) and standard (standard) survival. Patients with: Cohort A: metastatic pancreatic ductal adenocarcinoma Cohort B: glioblastoma IDHwt Cohort C: extensive small cell lung …
EXoPERT EMERALD Clinical Study
Invitro diagnostic test for multiple cancer diagnosis for patients with early-stage cancers by analyzing surface-enhanced Ramen spectroscopy (SERS) profiles of extracellular vesicles (EV) using artificial intelligence.
Ontario-wide Cancer TArgeted Nucleic Acid Evaluation
Substantial progress has been made in the treatment of cancer through the use of targeted therapies, but what works for one patient might not work for another patient. Certain drugs are now being developed that target specific molecules in the body that are believed to be part of the disease. …
The Gut Microbiome and Immune Checkpoint Inhibitor Therapy in Solid Tumors
The microbiome has the potential to serve as a robust biomarker of clinical response to immunotherapy. Additionally, microbial manipulation, through diet, exercise, prebiotics, probiotics, or microbially-derived metabolites, may prove to be beneficial in promoting anti-tumor immune responses. However, large prospective studies in humans with longitudinal sample collection and standardized methods …
Pan-tumor MRD Study
The purpose of this observational study is to collect clinical information, blood, and tumor tissue samples from participants diagnosed with stage I, stage II, or operable stage III cancer in select solid tumors. The information collected will be used to develop tests to better understand cancer, for example, to improve …
InAdvance: Surveillance, Prevention, and Interception in a Population at Risk for Cancer
This research study is creating a way to collect and store specimens and information from participants who may be at an increased risk of developing cancer, or has been diagnosed with an early phase of a cancer or a family member who has a family member with a precursor condition …
A Multicentre Study on Features of the Gut Microbiota of Patients With Critical Chronic Diseases in China
The human gut microbiome has been associated with many health factors but variability between studies limits the exploration of effects between them. This study aims to systematically characterize the gut microbiota of various critical chronic diseases, compare the similarities and differences of the microbiome signatures linked to different regions and …
Identification of Multiple Pulmonary Diseases Using Volatile Organic Compounds Biomarkers in Human Exhaled Breath
The goal of this observational study is to develop an advanced expiratory algorithm model utilizing exhaled breath volatile organic compound (VOC) marker molecules. This model aims to accurately diagnose mutiple pulmonary diseases. The primary objectives it strives to accomplish are: To assess the diagnostic accuracy of an exhaled breath VOC-assisted …
