简要总结
Background:
- AZD2171 is an experimental drug that may slow the growth of cancers by blocking angiogenesis (formation of new blood vessels).
- Cancer growth is dependent on angiogenesis for nutrition.
- Inhibiting angiogenesis is a new approach to cancer therapy.
Objectives:
- To determine the side effects of AZD2171 in children and adolescents with cancer.
- To determine the highest dose of AZD2171 that can safely be given to children and adolescents with cancer.
- To study how the body handles AZD2171.
- To determine the effects of AZD2171 on various factors related to angiogenesis.
- To determine if AZD2171 can inhibit cancer growth in children and adolescents.
Eligibility:
-Children and adolescents 2-18 years of age with treatment-resistant solid tumor cancers or acute myelogenous leukemia.
Design:
- About 40 patients may be included in the study.
- AZD2171 is given by mouth in treatment cycles of once a day for 28 days. Treatment may continue unless the cancer worsens or unacceptable side effects develop.
- Patients have periodic physical examinations, blood and urine tests and imaging tests (CT, X-rays, MRI) to evaluate disease throughout the course of treatment. Additional blood tests are done to study how the body handles AZD2171, to look for proteins that stimulate angiogenesis, to determine if certain blood vessel cells are affected by AZD2171, and for other research purposes.
- Biopsy tissue (when available) is examined for the receptor for new blood vessel formation.
详细描述
Background:
- Cediranib is a potent orally bioavailable inhibitor of VEGFR1, VEGFR2, VEGFR3 tyrosine kinase activity, but also inhibits c-kit and PDGFR-Beta in vitro.
- Phase I trials of Cediranib are ongoing in adults and the drug is well tolerated at doses up to 45 mg/d. The toxicity profile includes hypertension, hypoglycemia, elevated LFTs, fatigue, dysphonia, diarrhea, nausea and vomiting.
Objectives:
- To determine the maximum tolerated dose (MTD) and dose-limiting toxicities of orally administered Cediranib on a daily for 28 consecutive days schedule in children and adolescents with refractory childhood solid tumors.
- To define the toxicity spectrum of oral Cediranib in children and adolescents.
- To assess the pharmacokinetics and pharmacodynamics of oral Cediranib in children and adolescents.
- Assess growth plate volume in the right knee using non-contrast MRI scans prior to and during administration of cediranib.

- •Patients must have had their last dose of:
- •Cytotoxic chemotherapy:
- •Patients with solid tumors, the last dose of cytotoxic therapy must be at least 21 days prior to study entry.

- •Patients who have received an allogeneic BM or SC transplant must be at least 3 months post-transplant; and patients who have received an autologous BM or SC transplant must be at least 2-months post-transplant.
- •Patients must have recovered from the acute toxic effects of prior therapy before entry onto this trial.
- •Patients should be off colony stimulating factors such as filgrastim (G-CSF), sargramostim (GM-CSF), and IL-11 (with the exception of erythropoietin) for at least 72 hours prior to study entry. Patients receiving PEG-filgrastim (Neulasta ) must be at least 7 days from the last dose.

- •Patients receiving prophylactic anticoagulation for thrombosis are eligible if they meet criteria for adequate hemostatic function (PT and PTT less than or equal to 1.5 x ULN) and the thrombotic episode occurred greater than 3 months prior to enrollment. Use of anticoagulants or thrombolytics for care and maintenance of central venous catheters (e.g., intralumenal TPA) is acceptable.
- •Patients on thyroid replacement (levothyroxine, synthroid ) must be on a stable dose for at least 1 month.

- •Patient receiving corticosteroids must be on a stable or tapering dose for 14 days prior to study enrollment.
- •PERFORMANCE STATUS: Patients greater than 10 years old must have a Karnofsky performance level greater than 50, and children less than or equal to 10 years old must have a Lansky performance level greater than
- •HEMATOLOGICAL FUNCTION:
- •Patients with solid tumors must have adequate bone marrow function, defined as a peripheral absolute neutrophil count of greater than or equal to 1,500/microL, and a platelet count greater than or equal to 100,000/microL (transfusion independent).
