NCT00515892

Brief Summary

RATIONALE: The CAT-8015 immunotoxin can bind tumor cells and kill them without harming normal cells. This may be effective treatment for Non-Hodgkin's lymphoma (NHL) that has not responded to chemotherapy, surgery or radiation therapy. PURPOSE: Phase 1 dose escalation study to determine the maximum tolerated dose of CAT-8015 immunotoxin in treating patients who have Non-Hodgkin's lymphoma and do not respond to treatment.

Outcome Measures

Primary Outcomes (1)

  • Estimate the maximum dose that can be safely administered to a patient; Characterize the toxicity profile of CAT-8015; Study the clinical pharmacology of CAT-8015; Observe anti-tumor activity, if any.

Secondary Outcomes (1)

  • To assess the immunogenic potential of CAT-8015 to induce antibodies; To investigate the potential of biomarkers to predict any therapeutic or toxic response.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • DISEASE CHARACTERISTICS:
  • Confirmed diagnosis of B-cell non-Hodgkin's lymphoma
  • Measurable disease
  • Evidence of CD22-positive malignancy by the following criteria,
  • \> 30% of malignant cells from a disease site CD22+ by FACS analysis or,
  • \> 15% of malignant cells from a disease site must react with anti-CD22 by immunohistochemistry
  • Patients with indolent subtypes of CD22+ B-cell non-Hodgkin's lymphoma, including, but not limited to mantle cell lymphoma, follicular lymphoma and Waldenström's macroglobulinemia, are eligible if stage III-IV.
  • Patients must have failed at least two or more courses of prior standard chemotherapy and/or biologic therapy (e.g. Rituxan). Patients with progressive mantle cell lymphoma may be eligible if they have failed one prior standard therapeutic regimen.
  • PATIENTS CHARACTERISTICS
  • Performance Status
  • ECOG 0-2
  • Life Expectancy
  • Life expectancy of less than 6 months, as assessed by the principal investigator
  • Other
  • Patients with other cancers who meet eligibility criteria and have less than 5 years of disease free survival will be considered on a case-by-case basis
  • +2 more criteria

You may not qualify if:

  • History of bone marrow transplant
  • Pregnant or breast-feeding females
  • Patients whose plasma contains either a significant level of antibody to CAT-8015 as measured by ELISA, or antibody that neutralizes the binding of CAT-8015 to CD22 as measured by a competition ELISA.
  • HIV positive serology (due to increased risk of severe infection and unknown interaction of CAT-8015 with antiretroviral drugs)
  • Hepatitis B surface antigen positive
  • Uncontrolled, symptomatic, intercurrent illness including but not limited to: infections requiring systemic antibiotics, congestive heart failure, unstable angina pectoris, cardiac arrhythmia, psychiatric illness, or social situations that would limit compliance with study requirements
  • Hepatic function: serum transaminases (either ALT or AST) or bilirubin
  • ≥ Grade 2, unless bilirubin is due to Gilbert's disease
  • Renal function: Serum creatinine clearance ≤ 60mL/min as estimated by Cockroft-Gault formula
  • Hematologic function:
  • The ANC \< 1000/cmm, or platelet count \<50,000/cmm, if these cytopenias are not judged by the investigator to be due to underlying disease (i.e. potentially reversible with anti-neoplastic therapy).
  • A patient will not be excluded because of pancytopenia ≥ Grade 3, or erythropoietin dependence, if it is due to disease, based on the results of bone marrow studies
  • Baseline coagulopathy \> Grade 3 unless due to anticoagulant therapy.
  • Pulmonary function:
  • Patients with \< 50% of predicted forced expiratory volume (FEV1) or \<50% of predicted diffusing capacity for carbon monoxide (DLCO), corrected for hemoglobin concentration and alveolar volume. Note: Patient with no prior history of pulmonary illness are not required to have PFTs. FEV1 will be assessed after bronchodilator therapy.
