Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - 5 Azacytidine

Experimental: Phase I Dose-escalation - 5'azacytidine will be administered on Days 1-7 at a dose of 75mg/m2/day, followed by escalating doses of Carboplatin on Day 14 in a rolling 6 design. Carboplatin will be dosed initially at AUC 4. Dose level -1 will reduce 5'azacytidine to 50mg/m2/day.

Experimental: Posterior Fossa Ependymoma Expansion Arm - 5'azacytidine will be administered on days 1-7 and carboplatin will be administered on day 14 at the maximum tolerated dose achieved in the Phase I dose escalation to 20 patients with recurrent/refractory posterior fossa ependymoma.

Experimental: Recurrent Brain and Solid Tumour Expansion Arm - 5'azacytidine will be administered on days 1-7 and carboplatin will be administered on day 14 at the maximum tolerated dose achieved in the Phase I dose escalation up to 12 patients with recurrent/refractory brain and solid tumour.

Eligibility
Key inclusion criteria
1. Greater than the age of 1 year and under age 18 at the time of study enrolment
2. Recurrent or refractory brain or solid tumor, including recurrent or refractory ependymoma
3. Tissue from diagnosis or resection prior to registration must be available (either flash frozen tissue or an FFPE block)
4. Previous therapy with carboplatin will be permitted
5. Failed first line treatment (surgery, radiation therapy or chemotherapy) and should not be eligible for treatment with curative potential.
6. Be at least 4 weeks from the completion of myelosuppressive chemotherapy and/or biologic agents before starting day 1 of this study treatment
7. Be at least 14 days from the completion of radiation therapy and MIBG before starting day 1 of this study treatment
8. Be at least 3 months post hematopoetic stem cell rescue following myeloablative therapy before starting day 1 of this study treatment
9. Must have visible disease on imaging. Resection of visible disease is permitted while on study after two cycles including achievement of a gross total resection. If a resection is performed while on study, fresh frozen tissue should be submitted for analysis.
10. Concurrent medications will be limited to supportive medications/agents including but not limited to anti-emetics, steroids, analgesics and non-enzyme inducing anticonvulsants. Strong inducers of the P450 system will not be permitted. Other concurrent medications require approval of the study Sponsor.
11. Ability of the parent and/or child to understand and the willingness to sign a written informed consent document
12. Karnofsky = 50 for patients > 16 years of age and Lansky = 50 for patients = 16 years of age (See Appendix I for the Karnofsky-Lansky Scores). Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score. Patients with posterior fossa syndrome/cerebellar mutism demonstrating clear improvement post-surgically can be enrolled based on physician discretion
13. Adequate hepatic, renal, marrow and cardiac function as defined below within 28 days prior to cycle 1 day 1:

* Serum creatinine within normal institutional limits or creatinine clearance greater than 60mL/min
* Serum bilirubin <1.5 times upper limit of institutional normal. Higher levels are acceptable if these can be attributed to active hemolysis or ineffective erythropoiesis
* AST, ALT and Alkaline Phosphatase <3 times upper limit of institutional normal. If liver metastases are present, then <5 times upper limit of normal is permitted.
* Normal QTc interval at screening ECG (baseline echocardiogram is not required)
* Adequate marrow function defined below within 14 days prior to cycle 1 day 1:

* Leukocytes greater than or equal to 1000 x106/L
* Absolute neutrophil count greater than or equal to 0.75 x109/L
* Platelets greater than or equal to 75 x109/L
* Hemoglobin greater than or equal to 10g/dL (may be transfused).
Minimum age
1 Year
Maximum age
18 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Female patient who is pregnant or breast feeding (Lactating females must agree not to breast feed while taking azacitidine) or with childbearing potential and not willing to use a double method of contraception up to 3 months after the end of study treatment. Male patient who is not willing to use a barrier method of contraception up to 6 months after the end of study treatment.
2. Patients may not be receiving any other investigational agents within 30 days prior to day 1 of protocol treatment
3. Prior therapy with a DNA demethylase inhibitor
4. Evidence of cardiac toxicity (shortening fraction below 28%; shortening fraction measures and ratios the change in the diameter of the left ventricle between the contracted and relaxed states)
5. Abnormal coagulation parameters (PT >15 seconds, PTT>40 seconds, and/or INR >1.5)
6. Significant active cardiac disease within the previous 6 months including:

* NYHA class 3 or 4 CHF
* Unstable angina
* Myocardial infarction
7. Known or suspected hypersensitivity to azacitidine or mannitol carboplatin
8. Previous carboplatin exposure is not an exclusion criteria but previous allergic reaction to carboplatin will exclude enrolment.
9. Patient must not require use of enzyme inducing anticonvulsants; patients who are receiving an enzyme inducing anticonvulsant must be able to switch to a non-enzyme inducing anticonvulsant such as Levetiracetam, Clobazam, Lacosamide, Valproate or Topiramate at least 2 weeks prior to study enrolment.
10. Uncontrolled systemic fungal, bacterial or viral infection (defined as ongoing signs/symptoms related the infection without improvement despite appropriate antibiotics, antiviral therapy and/or other treatment)
11. Active viral infection with HIV or hepatitis type B or C Patients with advanced malignant hepatic tumors
12. Patients with advanced malignant hepatic tumors
