Study Details

Study Description

Brief Summary

The purpose of this study is to determine is Denileukin diftitox will be safe, well tolerated and induce a significant overall response alone and in combination with chemotherapy: ifosfamide, carboplatin and etoposide (ICE) and will be safe and well tolerated in a population of children, adolescents and young adults with relapsed or refractory anaplastic large cell lymphoma (ALCL).

Condition or Disease	Intervention/Treatment	Phase
Anaplastic Large-Cell Lymphoma	Drug: Denileukin Diftitox Drug: Denileukin diftitox, ifosfamide, cyclophosphamide, etoposide	Phase 2

Detailed Description

Despite significant progress in the treatment and outcome for childhood ALCL, the prognosis for children who develop progressive or recurrent disease is poor with < 30% DFS. Novel therapies are urgently needed for these subgroups of patients. One potential approach is the investigation of a new class of receptor targeted cytotoxic fusion proteins (denileukin diftitox). We have previously demonstrated that > 85% of children with ALCL express CD25. The human IL-2 receptor exists in three forms, low (CD25), intermediate (CD122/CD132) and high (CD25/CD122/CD132) affinity. DD is a recombinant DNA-derived cytotoxic fusion protein composed of the amino acid sequences for diphtheria toxin fragments followed by the binding sequences for the interleukin-2 receptor. Malignant cells expressing one or more of the subunits of the IL-2 receptor are found in certain leukemias and lymphomas including cutaneous T-cell lymphoma (CTCL). Clinical studies have shown therapeutic efficacy of DD alone and in combination with CHOP chemotherapy in CD25 expressing malignancies such as CTCL, CLL and lymphoma. We hypothesize that DD will be safe and efficacious in children with relapsed ALCL.

Eligibility Criteria

Criteria

Ages Eligible for Study:

2 Years to 24 Years

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Age: Patients must be ≥ 2.00 year and ≤ 24.99 years of age at the time of study entry.
Diagnosis:

Patients must have previous histologic verification of anaplastic large cell lymphoma (ALCL). Patients must be in first, second or third relapse or initial induction failure.

Disease Status: Patients must have measurable radiographic disease.
Performance Level: Karnofsky > 60% for patients > 16 years of age and Lansky > 60 for patients <16 years of age. Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
Prior Therapy

Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study. Patients who are post-allogeneic transplant should be off immunosuppressive agents prior to starting therapy. Steroid doses should also be stable or decreasing for at least 1 week prior to starting therapy.

Myelosuppressive chemotherapy: Must not have received within 2 weeks of entry onto this study (6 weeks if prior nitrosourea).

Biologic (anti-neoplastic agent): At least 7 days since the completion of therapy with a biologic agent. For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur. These patients must be discussed with the Study Chair on a case-by-case basis.

XRT: > 2 wks for local palliative XRT (small port); > 2 months must have elapsed if prior TBI, craniospinal XRT or if > 50% radiation of pelvis; > 6 wks must have elapsed if other substantial BM radiation.

Stem Cell Transplant or Rescue: No evidence of active graft vs. host disease and > 2 months must have elapsed since SCT.

Patients may not have received prior therapy with Denileukin Diftitox
