Brief Summary
Background
- HGS-ETR2 is a monoclonal antibody, produced in the laboratory from human genes.
- HGS-ETR2 targets a protein called the TRAIL receptor that is located on the surface of some tumor cells. When the TRAIL receptor is activated, it can cause the tumor cell to self-destruct. Objectives:
- To determine the highest dose of HGS-ETR2 that can be given safely in children and young adults with cancer.
- To study the pharmacology (how the body handles the drug) of HGS-ETR2 by measuring the amount of drug in the bloodstream over time before and after a dose is given to the patient.
- To determine if HGS-ETR2 can stop or slow tumor growth.
- To determine whether proteins in tumor tissue before treatment can predict whether the tumor will respond to HGS-ETR2 therapy. Eligibility:
- Patients 1 to 21 years of age with solid cancers that do not respond to standard therapy. Design:
- HGS-ETR2 is given through a vein (intravenously, IV) once every 14 days. Each treatment cycle is 28 days long and consists of two doses of HGS-ETR2.
- The dose of HGS-ETR2 is increased in successive small groups of patients until the maximum tolerated dose (highest dose with acceptable side effects) is determined.
- During the treatment period, patients have a physical examination at least once a week, and routine blood tests at least twice a week. These tests are done less frequently in later treatment cycles.
- Additional blood samples are drawn for immunology and pharmacology studies.
- Tests to monitor the size of the tumor (X-rays, CT scans, MRI, PET scans) are done periodically throughout the treatment period.
- Patients may continue to receive HGS-ETR2 until unacceptable side effects develop or the tumor grows.

Eligibility Criteria
You may qualify if:
- AGE: Patients must be greater than or equal to 1 years and less than or equal to 30 years of age in order to encompass a broad range of ages in children as well as to capture the young adult population which is highly represented in many of these types of sarcomas being studied.
- DIAGNOSIS: Histologically confirmed solid tumors, which may include but are not limited to rhabdomyosarcoma and other soft tissue sarcomas, Ewing s sarcoma family of tumors, osteosarcoma, neuroblastoma, Wilm s tumor, Hodgkin's or non-Hodgkin's lymphoma. Patients with primary or untreated metastatic CNS tumors or primary or metastatic hepatic tumors will not be treated on this study.
- MEASURABLE/EVALUABLE DISEASE: Patients must have measurable or evaluable tumors.
- PRIOR THERAPY:
- The patient s cancer must have relapsed following or failed to respond to standard therapy, and the patient s current disease state must be one for which there is no known curative therapy or therapy proven to prolong survival with an acceptable quality of life.
- Patients must have completed their last dose of irradiation, chemotherapy, monoclonal antibody, or investigational therapy at least 4 weeks prior to enrollment or their last dose of nitrosurea (CCNU, BCNU) 6 weeks prior to enrollment. For patients who have undergone autologous stem cell transplantation, at least 3 months must have elapsed since transplant.
- Patients must have recovered from the toxic effects of all prior therapy prior to enrollment.
- Patients must have been off colony stimulating factors (e.g. G-CSF, GM-CSF, Epo) for at least 72 hours prior to enrollment.
- Patients must have completed any biological therapy (including investigational therapies) at least 7 days prior to study entry.
- PERFORMANCE STATUS: Patients greater than 10 years old must have a Karnofsky Score of greater than or equal to 50 and children less than or equal to 10 years old must have a Lansky score of greater than 50. Patients who are unable to walk because of paralysis or weakness, but who are up in a wheelchair will be considered ambulatory for the purpose of calculating the performance score.
- HEMATOLOGIC FUNCTION: Patients must have adequate bone marrow function, defined as a peripheral absolute granulocyte count of greater than or equal to 1000/microliter, hemoglobin greater than or equal to 8 gm/dl, and a transfusion independent platelet count greater than or equal to 75,000/microliter.
- Cardiac Function: Patients must have an ejection fraction of greater than 40% via MUGA or Echo or a shortening fraction greater than 27% by Echo and must not have had a history of congestive heart failure.
- HEPATIC FUNCTION: Aspartate transaminase (AST) and alanine transaminase (ALT), less than or equal to 2.5-fold the upper limit of normal (ULN). Direct bilirubin within normal limits.
- RENAL FUNCTION: Patients must have normal age-adjusted serum creatinine (see Table below) OR a creatinine clearance greater than or equal to 60 mL/min/1.73 m(2).
- Age Less than or equal to 5 with a max serum creatinine (mg/dl) of 0.8
- +7 more criteria
You may not qualify if:
- Clinically significant unrelated systemic illness, such as serious infections or organ dysfunction, which in the judgment of the Principal or Associate Investigators would compromise the patient s ability to tolerate the agents in this trial or are likely to interfere with the study procedures or results.
- Patients with a history of allogeneic bone marrow transplantation. Patients who have received autologous stem cell transplantation are eligible greater than 3 months after completion of therapy if they meet other eligibility requirements.
- Patients with hepatic tumors or metastases are excluded due to the potential for hepatotoxicity with agents that target the TRAIL-R pathway. Patients with primary CNS tumors will be excluded due to unknown penetration into the CNS.
- Untreated CNS metastases will render the patient ineligible however patients with a previous history of CNS metastases are eligible if: the metastases have been treated with surgery and/or radiotherapy, are clinically stable as evidenced by no requirements for corticosteroids, the patient has no evolving neurologic deficits and no change in residual brain abnormalities without specific therapy over 6 weeks.
- Pregnant or breastfeeding females are excluded because the risks of lexatumumab to the developing fetus or nursing child are unknown.
- Patients currently receiving other investigational agents.
- History of any infection requiring hospitalization or parenteral antibiotics within 2 weeks of study entry.
- Co-existing medical illness that would place the subject at undue risk.
- On immunosupressant therapy (with the exception of prednisone up to 10 mg/day, or dexamethasone up to 4 mg/day), or with known human immunodeficiency virus (HIV) infection or hepatitis B or C. Subjects with immune deficiency are excluded due to their increased risk of life threatening toxicity when treated with anticancer agents.
