OBJECTIVES: Primary * Determine the maximum tolerated dose of LMB-2 immunotoxin in pediatric patients with CD-25 positive relapsed or refractory leukemia or lymphoma. * Determine the toxic effects of this drug in these patients. * Determine the pharmacokinetics of this drug, including the terminal elimination serum half-life, area under the curve, volume of distribution, and relationship to disease burden, in these patients. Secondary * Evaluate the immonogenicity of this drug in these patients. * Determine response in patients treated with this drug. * Determine changes in lymphocyte subsets, immunoglobulin levels, serum cytokines, and soluble cytokine receptor levels in patients treated with this drug. OUTLINE: This is a dose-escalation, multicenter study. Patients receive LMB-2 immunotoxin IV over 30 minutes on days 1, 3, and 5. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression, neutralizing antibodies (i.e., > 75% of the activity of 1 µg/mL of LMB-2 immunotoxin), or unacceptable toxicity. Patients achieving complete remission (CR) receive 2 additional courses beyond CR. Patients with acute lymphoblastic leukemia also receive cytarabine and hydrocortisone intrathecally once monthly concurrent with restaging lumbar punctures. Cohorts of 3-6 patients receive escalating doses of LMB-2 immunotoxin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, a total of 12 patients are treated at that dose level. Patients are followed weekly for 1 month and then monthly thereafter. PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study within 2-4 years.

Protocole

Cette section fournit des détails sur le plan de l'étude, y compris la manière dont l'étude est conçue et ce qu'elle évalue.
Détails du design

40 participants à inclure

Nombre total de participants que l'essai clinique vise à recruter.

Traitement

Cette étude teste un ou plusieurs traitements pour évaluer leur efficacité contre une maladie ou un problème de santé spécifique. L'objectif est de voir si un nouveau médicament ou une thérapie fonctionne mieux, ou provoque moins d'effets secondaires que les options existantes.

Éligibilité

Les chercheurs recherchent des patients correspondant à une certaine description appelée critères d'éligibilité : état de santé général ou traitements antérieurs du patient.
