and reversible toxicities related to prior therapy and have adequate washout prior to study
entry as follows:
Surgery:
Previous major surgery is permitted provided that it has been at least 28 days prior to
registration and wound healing has occurred. Additionally, at least 7 days must have
elapsed since last biopsy or other minor surgery and wound healing must have occurred.
Radiation:
Prior radiotherapy is permitted provided that from last dose to registration:
- At least 90 days have elapsed from total body irradiation, craniospinal radiotherapy
or if = 50% radiation of pelvis.
- At least 6 weeks have elapsed from other substantial bone marrow irradiation.
- At least 2 weeks have elapsed from local palliative radiotherapy (small port),
- At least 8 weeks have elapsed from 131I-MIBG therapy for neuroblastoma.
Chemotherapy:
Prior myelosuppressive chemotherapy is permitted provided that it has been at least 3 weeks
(6 weeks if nitrosurea) from last administration.
Prior therapy with vinblastine, mTOR inhibitors (such as temsirolimus or sirolimus) is
permitted provided patients did not develop progressive disease during treatment and
patients have never had to discontinue treatment due to severe adverse events such as
interstitial lung disease. At least 3 weeks must have elapsed from the last administration
of these agents and registration.
Other Therapy:
Patients may have received other therapies provided that an adequate time has elapsed from
completion of therapy/last dose as follows:
- At least 60 days from stem cell transplant/rescue without total body irradiation and
no signs of graft-versus-host disease (GVHD).
- At least 7 days (2 weeks for peg-filgrastim) from completion of therapy with
hematopoietic growth factors.
- At least 3 half-lives from last administration of monoclonal antibodies.
- At least 6 weeks from any other immunotherapy (e.g. vaccines).
- For biologic anti-neoplastic agents, the longer of the following must have elapsed
from last administration prior to study entry: At least 2 weeks or, Standard cycle
length of prior regimen or, 5 half-lives.
- Adequate Bone Marrow Function, defined as:
- Absolute neutrophil count (ANC) = 1.0x10^9/L.
- Platelets = 100 x 10^9/L (transfusion independent defined as not receiving platelet
transfusions within 7 days prior to registration).
- Hemoglobin > 80 g/L (may receive RBC transfusions). Patients with known bone marrow
disease will be eligible for the study provided they meet bone marrow criteria above
and they are not known to be refractory to red cell or platelet transfusions.
- Adequate Renal Function, defined as:
- Measured creatinine clearance/GFR = 70 mL/min/1.73 m2 OR,
- Serum creatinine = 1.5 x ULN for age.
- Adequate Liver Function, defined as:
- Total bilirubin = 1.5 x upper limit normal for age.
- ALT = 1.5 x upper limit of normal.
- Serum albumin = 20 g/L.
- Adequate Metabolic Function, defined as:
- Serum triglyceride level = 3.42 mmol/L (300 mg/dL).
- Serum cholesterol level = 7.75 mmol/L (300 mg/dL).
- Blood glucose = ULN for age. Initial sampling may be random; if abnormal, fasting
blood glucose must be obtained and be within the upper normal limits for age.
- Adequate Pulmonary Function, defined as:
- No dyspnea at rest.
- O2 saturations of = 92% on room air.
- Patients with any baseline respiratory symptoms, or with a history of pulmonary
toxicity, and who are old enough to complete pulmonary function tests, should
have documented FEV1 and vital capacity = 50% normal value.
- Electrolytes: = grade 1 (Potassium, Calcium, Magnesium, Phosphate)
- Patient or guardian consent must be obtained on all patients according to local
Institutional and/or University Human Experimentation Committee requirements. Children
> 8 years old whose parent or guardian has signed consent on their behalf may also
sign assent if desired
- Patients must be accessible for treatment and follow up. Patients registered on this
trial must be treated and followed at the participating centre
- In accordance with NCIC CTG policy, protocol treatment is to begin within 5 working
days of patient registration
Exclusion Criteria:
- Patients with serious illness or medical condition that would not permit the patient
to be managed according to the protocol including, but not limited to:
1. Active or uncontrolled infections;
2. Uncontrolled diabetes;
3. Any other medical conditions that might be aggravated by treatment;
4. History of an underlying inherited or ongoing bleeding disorder;
5. Any factors that increase the risk of QTc prolongation or risk of arrhythmic
events (e.g. heart failure, hypokalemia, congenital long QT syndrome, family
history of long QT syndrome or unexplained sudden death under 40 years of age) or
mean resting corrected QT interval (QTc) > 470 msec).
- Patients with a history of allergic reactions or known hypersensitivity to the study
drug(s) or their components, or compounds of similar chemical or biologic composition.
- Patients with lymphoma or solid tumours (except primary CNS tumours) who have
untreated brain metastases, untreated spinal cord compression or meningeal metastases
are not eligible (CNS imaging is not required to rule this out unless there is a
clinical suspicion of CNS disease). Patients with treated brain metastases who have
radiologic evidence of stable brain metastases, with no evidence of cavitation or
hemorrhage in the brain lesion, are eligible providing that they are asymptomatic. If
being treated with corticosteroids, must be at a stable or decreasing dose for at
least 7 days prior to study entry.
- Concurrent Medications
- Patients receiving other investigational agents.
- Patients receiving other anti-cancer agents, or radiation therapy.
- Patients receiving angiotensin-converting enzyme (ACE) inhibitors.
- Patients receiving QT/QTc-prolonging drugs.
- Patients receiving anticoagulants.
- Patients receiving anti-GVHD or agents to prevent organ rejection
post-transplant.
- Patients receiving strong/potent CYP3A4/5 substrates/inhibitors/inducers. These
agents must have been discontinued for at least 14 days prior to registration.
Grapefruit juice is also not permitted for at least 14 days prior to registration
and at any time during study participation.
- Pregnancy tests must be obtained in girls who are post-menarchal. Males or females of
reproductive potential may not participate unless they have agreed to use a highly
effective contraceptive method. Pregnant or breast feeding females will not be entered
on this study due to the potential fetal and teratogenic adverse events.
- Patients who in the opinion of the investigator may not be able to comply with the
safety monitoring requirements of the study.
