Study Description

This study evaluates the safety of a type of treatment called HER2 CAR T cells (short for HER2 chimeric antigen receptor T cells). In addition to looking for side effects, we will study how well this treatment works against a brain tumor called ependymoma that has come back after treatment (recurrent) or has not responded well to treatment (progressive) in children. The HER2 CAR T cells used in this trial are made from the patient's own blood.

A new gene, called the HER2 CAR, will be inserted into patient's cells to allow them to recognize a protein on the tumor called HER2. These HER2-specific CAR T cells may be able to target and kill ependymoma tumors. This research is also studying how doable it is to provide this type of CAR T cell treatment to children being treated at different hospitals.

Inclusion Criteria

• Participants must have a diagnosis of ependymoma that is has come back or progressed.
• Patient must be ≥ 1 but ≤ 22 years of age at the time of enrollment for treatment.
• Participants must be up and about for 60% of their waking hours
• Patients must have received last dose of previous chemotherapy at least 21 days before enrollment.
• Patient must meet all organ function, bone marrow function and laboratory criteria
• The patient or parent/guardian can understand the consent and is willing to sign a written informed consent document according to institutional guidelines. Age- and developmentally appropriate assent should be obtained as required by institutional guidelines.

Additional inclusion and exclusion criteria applies and will be discussed with you by the study team.

Study Description

This is a phase I/II study that studies the drug SNDX-5613 in patients with acute leukemia. In phase 1, the dose will be increased to find the maximum tolerated dose of SNDX-5613 and the recommended dose for the next phase will be determined. In phase 2, patients will be given the recommended phase 2 dose determined in phase 1, and the safety and efficacy in patients with various tumour mutation will be studied. 

Inclusion Criteria

• Patients must have active acute leukemia with certain genetic characteristics
• Patients must be over 30 days old 
• Patients must be up and about more than 50% of waking hours (if applicable)
• Adequate time must have passed from all previous treatments (i.e at least 60 days must have passed from last radiation treatment/stem cell infusion (if applicable))
• Adeqaute organ function
• Blood work must come back within acceptable ranges
• Patients of child bearing potential must be willing to use a highly effective method of contraception from the time of enrollment to 120 days after the last study drug dose
• Patients and/or their families/caregivers must sign a consent form outlining all assessments and requirements

Study Description

Diffuse Intrinsic Pontine Glioma (DIPG) is an aggressive brain tumour with no effective treatment and no chance of long-term survival . When this brain tumour grows back after the initial radiation therapy, it is known as progressive or recurrent DIPG.

This study will investigate how long a second treatment with radiation (re-irradiation) keeps progressive or recurrent DIPG from growing again and the overall survival of these patients. All children enrolled will be treated with re-irradiation.

Inclusion Criteria

• The patient is 17 years of age or younger at the time of first or second relapse or progression of disease
• The patient has no evidence of metastases on MRI of the brain and the spine
• The patient has received radiation in the past, given to a total dose of <60 Gy
• At least 180 days (6 months) have elapsed from the last day of primary radiation
• Multiple other inclusion and exclusion criteria could apply and will be reviewed by your treating team

Study Description

This clinical trial studies the side effects and how well selpercatinib (a medication taken by mouth) works in treating patients with solid tumors and brain tumours with a change in a gene called RET. 

Selpercatinib may stop the growth of cancer cells with RET gene changes by blocking the RET enzymes needed for cell growth.

Inclusion Criteria

• Age between 6 months and 21 years
• Solid tumors and brain tumours with a change in a gene called RET
• Cancer that has come back (relapse) or is not improving despite treatment (progression)
• Multiple other inclusion and exclusion criteria could apply and will be reviewed by your treating team

Study Description

This study is looking at a new drug called selumetinib to see if it works as well as (or better than) the usual treatment (drugs called carboplatin/vincristine) for children with a type of brain tumor called low grade glioma. This study is also checking if selumetinib is better for helping improve vision for children with these tumors. Selumetinib works by blocking a substance called an enzyme that the tumor cells need to grow, which can help kill them. The regular treatment uses different drugs that stop tumor cells from growing in different ways. This study will compare to see which method is better. 

Inclusion Criteria

• Patients must be >= 2 years and =< 21 years at the time of enrollment
• Patients must have neurofibromatosis type 1 (NF1), newly diagnosed or have previously diagnosed NF-1 associated LGG that has not been treated with any modality other than surgery
• Additional inclusion criteria applies for patients with optic pathway gliomas, if applicable
• Patient must meet all of the bloodwork and organ function requirements outlined in the study
• Patients with a known seizure disorder should be stable and should have not experienced a significant increase in seizure frequency within 2 weeks prior to enrollment
• Patients must have an adequate performance status 
• Patients must have the ability to swallow whole capsules
• All patients and/or their parents or legal guardians must sign a written informed consent.

Other inclusion and exclusion criteria applies and will be discussed with you by the study team.

Study Description

This study will evaluate the combination of two drugs called favezelimab and pembrolizumab to see how effective and safe it is for treating patients with a cancer called lymphoma. There are various different kinds of lymphoma, this study is for patients with classical Hodgkin, indolent non-Hodgkin or diffuse large B-cell lymphoma. 

Inclusion Criteria

• Participants must be 18 years of age or older 
• Participants must have a diagnosis of:
  • classical Hodgkin lymphoma (cHL)
  • diffuse large B-cell lymphoma (DLBCL)
  • indolent non-Hodgkin lymphoma (iNHL)
• Must have a tumour that can be measured on CT or MRI 
• Participant should be well enough to carry out light daily tasks, e.g., light house work, office work, normal activities

Other inclusion and exclusion criteria may apply and will be discussed with you by the study team.

Study Description

The purpose of this study is to find out what effects new combinations of treatment will help in treating a cancer called lymphoma. New promising treatment strategies will be added to this study as they are available to be compared against the standard treatment.

Inclusion Criteria

• Participants must have one of the following diagnoses: 
  • Diffuse large cell lymphoma, B-cell (includes primary mediastinal B-cell lymphoma, T-cell rich B-cell lymphoma)
  • Previous indolent lymphoma with transformation to diffuse large B-cell lymphoma at most recent relapse
