Randomized Study of Nivolumab+Ipilimumab+/- SBRT for Metastatic Merkel Cell Carcinoma
The purpose of this study is to test the effectiveness, safety, and tolerability of the drugs nivolumab plus ipilimumab with or without the addition of stereotactic body radiation therapy (SBRT). Nivolumab is an antibody (a type of human protein) that is being tested to see if it will stimulate the body's immune system to work against tumor cells. This study will test an investigational use of nivolumab.

Randomized Trial of Topotecan With M6620, an ATR Kinase Inhibitor, in Small Cell Lung Cancers and Small Cell Cancers Outside of the Lungs
This phase II trial studies how well berzosertib (M6620) works when given in combination with topotecan hydrochloride (topotecan) compared with topotecan alone in treating patients with small cell lung cancer that has come back (relapsed), or small cell cancer that arises from a site other than the lung (extrapulmonary). Drugs used in chemotherapy, such as topotecan hydrochloride, work by damaging the DNA (deoxyribonucleic acid) in tumor cells, causing those cells to die and the tumor to shrink. However, some tumor cells can become less affected by chemotherapy because they have ways to repair the damaged DNA. The addition of M6620 could help topotecan hydrochloride shrink the...

Reduced Craniospinal Radiation Therapy and Chemotherapy in Treating Younger Patients With Newly Diagnosed WNT-Driven Medulloblastoma
This phase II trial studies how well reduced doses of radiation therapy to the brain and spine (craniospinal) and chemotherapy work in treating patients with newly diagnosed type of brain tumor called WNT)/Wingless (WNT)-driven medulloblastoma. Recent studies using chemotherapy and radiation therapy have been shown to be effective in treating patients with WNT-driven medulloblastoma. However, there is a concern about the late side effects of treatment, such as learning difficulties, lower amounts of hormones, or other problems in performing daily activities. Radiotherapy uses high-energy radiation from x-rays to kill cancer cells and shrink tumors. Drugs used in chemotherapy, such...

Regorafenib With Temozolomide With or Without RT in MGMT-Methylated, IDH Wild-type GBM Patients
This study will evaluate the addition of regorafenib to standard of care treatment with TMZ as adjuvant therapy, and in combination with TMZ+RT as concomitant therapy. The standard of care for newly diagnosed GBM (ndGBM) includes surgical resection to the extent that is safely feasible, followed by RT plus concomitant TMZ chemotherapy, and up to 6 months of adjuvant TMZ. The dose escalation will be explored following a "3+3" design, escalating oral doses of regorafenib in combination with adjuvant (maintenance) TMZ (cohort A) to estimate the MTD of regorafenib as adjuvant (maintenance) therapy. After finding the MTD in the Adjuvant Therapy dose escalation, the Concomitant...

Response and Biology-Based Risk Factor-Guided Therapy in Treating Younger Patients With Non-high Risk Neuroblastoma
This phase III trial studies how well response and biology-based risk factor-guided therapy works in treating younger patients with non-high risk neuroblastoma. Sometimes a tumor may not need treatment until it progresses. In this case, observation may be sufficient. Measuring biomarkers in tumor cells may help plan when effective treatment is necessary and what the best treatment is. Response and biology-based risk factor-guided therapy may be effective in treating patients with non-high risk neuroblastoma and may help to avoid some of the risks and side effects related to standard treatment.

Retifanlimab and Epacadostat in Combination With Radiation and Bevacizumab in Patients With Recurrent Gliomas
In this study, the investigators propose to combine retifanlimab with radiation therapy (RT) and bevacizumab with or without epacadostat in the treatment of recurrent glioblastoma (GBM). The investigators hypothesize that this combination provides a powerful synergy between RT and immune modulators to produce more robust anti-tumor immune response, induce tumor regression and improve overall survival.

Review of Medical Records of Patients Who Have Been Treated With Lutetium at the Cross Cancer Institute Between January 2010 and April 30, 2014
Retrospective review of the medical files of 115 patients with neuroendocrine tumours who were treated with Lutetium-177 DOTA-TATE under Health Canada's Special Access Programme (SAP) at the Cross Cancer Institute between January 2010 and April 30, 2014. Efficacy, safety, and other relevant data will be collected to support a separate clinical trial application.

rhIL-7-hyFc on Increasing Lymphocyte Counts in Patients With Newly Diagnosed Non-severe Lymphopenic Gliomas Following Radiation and Temzolomide
The investigators have developed a phase I/II clinical trial to evaluate the effect of rhIL-7-hyFc on lymphocyte counts in patients with high grade glioma (HGG). A phase I study will test whether rhIL-7-hyFc can be safely administered to patients with HGG. Six doses of rhIL-7-hyFc will be tested using a mix of Accelerated Phase and standard 3+3 dose-escalation design. The phase II portion to test effect of rhIL-7-hyFc on lymphocyte counts will use placebo-controlled randomization in HGG patients whose treatment include the standard radiation therapy (RT) and temozolomide (TMZ).

Ribociclib (LEE011) in Preoperative Glioma and Meningioma Patients
In the proposed trial, patients will be administered ribociclib prior to surgical resection of their tumor. Patients will be enrolled in time-intervals sequentially (non-randomized). All patients will be orally-administered 5 doses of LEE011 (900 mg/d) with the final dose occurring at one of 3 intervals before brain tumor resection.
