The purpose of this study is to follow participants with Cushing's syndrome during the course of their routine care and to form a data registry to study long term participant outcomes.
The aim of this project is to improve biological collections of patients presenting rare neurological disorders with known or suspected autoimmune origin. This collection will provide appropriate biological samples to identify new biomarkers and to be accessible to the medical, scientific and industrial communities for the identification of new therapeutic strategies.
This study will collect blood and urine samples from patients undergoing radiation therapy for glioblastoma multiforme (a type of brain tumor) to investigate the effects of this treatment on blood cells and certain proteins. The information from this study may help scientists develop new tests to measure radiation exposure and find new ways to treat cancer with radiation, and help determine which kinds of patients or tumors respond better to radiation therapy. Two proteins of particular interest in this study and which may be involved in the recurrence of cancer are VEGF (vascular endothelial growth factor) and MMPs (matrix metalloproteinases). Patients 18 years of age and older...
The purpose of this study is to assess the feasibility, safety and efficacy of combination immunotherapy based on CAR T cells, cytotoxic T lymphocytes (CTLs), and dendritic cell (DC) vaccines modified with GM-CSF and B7-2 (CD86) against melanoma, which targets CAR T specific surface antigens such as GD2, CTL specific antigens such as MAGE-A4, gp100 and a pool of melanoma specific antigens presented by the DCs. Another goal of the study is to learn more about the function and persistence of the CAR T cells and antigen-specific immune effectors in patients.
Aggressive growing meningiomas resistant to multiple surgeries and radiotherapy constitute an unmet pharmaceutical need in neurooncology, leading to a fatal issue within a few months. Grade II-III meningiomas progression-free survival (PFS) 6 is at 10-15%. Median PFS grade III meningioma is approximate 3 years. Alpelisib is a well-tolerated Phosphoinositide 3-kinase α (Pi3Kα) specific inhibitor. However, phosphatidylinositol-3-kinase (PI3K) and the mammalian target of rapamycin (mTOR) inhibition does not induce apoptosis in vitro and induces an antiproliferative effect without any radiologic response in most treated patients. Trametinib, a mekinist (MEK) inhibitor is currently...
Meningioma, the most common intracranial primary tumor of the central nervous system predominantly affects people in their fifties. Meningiomas are generally subdivided into two entities: a priori non-aggressive meningiomas (grade 1), and meningiomas at high risk of aggressive behavior (grade 2/atypical and 3/anaplastic). The current conventional treatments for meningioma are surgery and radiotherapy. When these treatments are no longer feasible, meningiomas are considered refractory irrespectively of grade, and in these rare entities, the therapeutic arsenal is reduced to the few treatments that have shown limited efficacy. Refractory, and particularly grades 2 and 3 meningiomas,...
This study aims to evaluate the efficacy and safety of the VPX regimen, a novel combination of teniposide, PD-1 monoclonal antibody and selinexor, in patients with relapsed/refractory (R/R) primary central nervous system lymphoma (PCNSL) who have progressed after high-dose methotrexate (HD-MTX)-based systemic therapy. By investigating this therapeutic approach, we seek to establish a new treatment paradigm that may improve clinical outcomes of this high-risk population.
This phase II trial determines if the combination of ONC201 with different drugs, panobinostat or paxalisib, is effective for treating participants with diffuse midline gliomas (DMGs). Despite years of research, little to no progress has been made to improve outcomes for participants with DMGs, and there are few treatment options. ONC201, panobinostat, and paxalisib are all enzyme inhibitors that may stop the growth of tumor cells by clocking some of the enzymes needed for cell growth. This phase II trial assesses different combinations of these drugs for the treatment of DMGs.
When cancer spreads to the brain, doctors often use a precise type of radiation therapy called stereotactic radiosurgery (SRS) to treat these tumors. This treatment can effectively control brain tumors while helping protect healthy brain tissue. However, when brain tumors or the areas where tumors were surgically removed are larger, treatment outcomes in terms of side effects and tumour control can become worse. Specifically, standard SRS on larger areas can have lower tumour control and higher risk of side effects, particularly a condition called radiation necrosis, which can cause swelling and damage in nearby healthy brain tissue. Currently at Sunnybrook, large brain tumors...
This cluster-randomized comparative effectiveness trial compares a technology-based supportive cancer care (SCC) approach with a redesigned team-based supportive cancer care (SCC) approach.
