Description

Summary

This is a phase I study of temsirolimus (Torisel) combined with dexamethasone, cyclophosphamide and etoposide in patients with relapsed acute lymphoblastic leukemia (ALL), lymphoblastic lymphoma (LL) or peripheral T-cell lymphoma (PTL).

Official Title

A Phase I Trial of Temsirolimus (CCI-779, Pfizer, Inc.) in Combination With Etoposide and Cyclophosphamide in Children With Relapsed Acute Lymphoblastic Leukemia and Non-Hodgkins Lymphoma

Details

Studies have shown that mTOR inhibitors (MTI) inhibit growth of pre-B and T-cell ALL cell lines in vitro and in ALL xenograft models. The MTI temsirolimus was chosen for use in this study due to its weekly intravenous dosing, its more predictable blood levels, and availability of a single-agent pediatric MTD and its sustained biologic effect due to conversion to sirolimus. This study will determine the maximum tolerated dose of temsirolimus that can given in combination with dexamethasone, cyclophosphamide and etoposide in relapsed ALL, LL or PTL. A standard 3-patient cohort dose-escalation design will be used. Response to treatment will be evaluated. Biology tests will be done to evaluate minimal residual disease (MRD), temsirolimus' effect on glucocorticoid resistance, and mTOR inhibition.

XRT: At least 14 days after local palliative XRT (small port); At least 84 days must have elapsed if prior TBI, craniospinal XRT or if greater than or equal to 50% radiation of pelvis; At least 42 days must have elapsed if other substantial marrow radiation.

Stem Cell Infusion: No evidence of active graft vs. host disease and at least 84 days must have elapsed after transplant or stem cell infusion.

Study specific limitations on prior therapy: Patient may not have received therapy with an mTOR inhibitor.

Adequate Bone Marrow Function Defined as: Blood counts are not required to be normal prior to enrollment on trial. However, platelet count must be greater than or equal to 20,000/mm3 to initiate therapy (may receive platelet transfusions). Patients should not be known to be refractory to red blood cell or platelet transfusions.

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 and Australia)
  • 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 study therapy.

    Infection Criteria

Patients are excluded if they have:

  • Positive blood culture within 48 hours of study enrollment;

    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.
