Female patients of childbearing potential must have a negative urine or serum
pregnancy test confirmed prior to enrollment.
Female patients with infants must agree not to breastfeed their infants while on this
Male and female patients of child-bearing potential must agree to use an effective
method of contraception approved by the investigator during the study.
Random or fasting glucose within the upper limits of normal for age. If the initial
blood glucose is non-fasting and above normal limits a fasting glucose can be
obtained and must be within the upper limits of normal for age.
Corticosteroids: Patients receiving corticosteroids who have not been on a stable or
decreasing dose of corticosteroid for at least 7 days prior to enrollment are not
Investigational Drugs: Patients who are currently receiving another investigational
drug are not eligible. The definition of "investigational" for use in this protocol
means any drug that is not licensed by the FDA, Health Canada or the Therapeutic
Goods Administration to be sold in the countries they govern. (United States, Canada
Anti-cancer Agents: Patients who are currently receiving or may receive while on
therapy, other anti-cancer agents, radiation therapy or immunotherapy are not
eligible [except leukemia patients receiving hydroxyurea, which may be continued
until 24 hours prior to start of protocol therapy]. Intrathecal chemotherapy (at the
discretion of the primary oncologist) may be given up to one week prior to the
initiation of the dexamethasone.
Anti-GVHD or agents to prevent organ rejection post-transplant: Patients who are
receiving cyclosporine, tacrolimus or other agents to prevent either
graft-versus-host disease post bone marrow transplant or organ rejection post
transplant are not eligible for this trial.
Anticoagulants: Patients who are currently receiving therapeutic anticoagulants
(including aspirin, low molecular weight heparin, and others) are not eligible.
Angiotensin-converting enzyme (ACE) inhibitors: Patients who are currently receiving
ACE inhibitors are not eligible due to the development of angioneurotic edema-type
reactions in some subjects who received concurrent treatment with temsirolimus + ACE
Enzyme inducing Anti-convulsants: Patients who are currently receiving enzyme
inducing anticonvulsants (ie phenytoin, phenobarbitol, or carbamazepine) are not
eligible. Stabilizing on a non-hepatic inducing metabolizing anti-convulsant (ie:
gabapentin or levetiracetam) prior to study entry is acceptable.
Patients receiving treatment with azoles such as fluconazole or voriconazole which
are potent inhibitors of temsirolimus metabolism.
Patients are excluded if they have:
Positive blood culture within 48 hours of study enrollment
Fever above 38.2 within 48 hours of study enrollment with clinical signs of
infection. Fever that is determined to be due to tumor burden is allowed if patients
have documented negative blood cultures for at least 48 hours prior to enrollment and
no concurrent signs or symptoms of active infection or hemodynamic instability.
Active fungal, viral, bacterial, or protozoal infection requiring IV treatment.
Chronic prophylaxis therapy to prevent infections is allowed.
Patients with Down syndrome and Fanconi Anemia are excluded.
Patients will be excluded if they have significant concurrent disease, illness,
psychiatric disorder or social issue that would compromise patient safety or
compliance with protocol treatment or required observations, interfere with consent,
study participation, follow up, or interpretation of study results.
Patients with known optic nerve and/or retinal involvement (because it may not be
possible to safely delay irradiation) are not eligible. Patients presenting with
visual disturbances by history or physical exam should have an ophthalmological exam
and, if indicated, an MRI to determine optic nerve or retinal involvement.
