Refractory Hodgkin Lymphoma Clinical Trial

Official title: A Phase 2 Trial of Yttrium-90 Labeled Anti-CD25 Monoclonal Antibody Combined With BEAM Chemotherapy (aTac-BEAM) Conditioning for Autologous Hematopoietic Cell Transplantation (AHCT) in Patients With Primary Refractory or Relapsed Hodgkin Lymphoma

Clinical Trial Summary

This phase II trials studies the effects of yttrium-90 labeled anti-CD25 monoclonal antibody combined with BEAM chemotherapy conditioning in treating patients with Hodgkin lymphoma that does not response to treatment (refractory) or has come back (relapsed). Yttrium-90-labeled anti-CD25 is an antibody (proteins made by the immune system to fight infections) that is attached to a radioactive substance and may kill cancer cells and shrink tumors. Chemotherapy drugs, such as carmustine, etoposide, cytarabine, and melphalan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before a peripheral blood stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow.

Clinical Trial Description

PRIMARY OBJECTIVE: I. Evaluate the anti-lymphoma activity of the aTac-carmustine (BCNU), etoposide, cytarabine (cytosine arabinoside), and melphalan (BEAM) regimen as conditioning for autologous hematopoietic cell transplantation (AHCT); assessed by 2-year progression-free survival (PFS). SECONDARY OBJECTIVES: I. Estimate the overall survival (OS) probability and cumulative incidence of relapse/progression, and non-relapse mortality (NRM) at 100-days, 1-year and 2-years. II. Summarize toxicities by type, frequency, severity, attribution, time course and duration. III. Evaluate short and long-term complications, including: delayed engraftment (neutrophil and platelet), infection, and myelodysplasia (MDS). EXPLORATORY OBJECTIVES: I. Evaluate potential changes in Hodgkin lymphoma biological markers of patients treated with 90Y basiliximab BEAM via analyses of serial blood samples. II. Assess the potential association between pre-AHCT CD25 expression levels and post-AHCT outcomes. OUTLINE: Patients receive 'cold' basiliximab intravenously (IV) followed by yttrium Y 90 basiliximab IV on day -14. Patients also receive carmustine IV on over 4 hours day -6, etoposide IV over 1 hours once daily (QD) and cytarabine IV over 2 hours twice daily (BID) or QD on days -5 to -2, and melphalan IV over 1 hours on day -1. Patients then receive hematopoietic progenitor cell apheresis (HPC-A) product via infusion on day 0. Beginning day 5, patients receive granulocyte colony-stimulating factor (G-CSF) (or biosimilar) subcutaneously (SC) or IV until absolute neutrophil count (ANC) > 500 for 3 consecutive days or according to the treating physician's best clinical judgement. After completion of study treatment, patients are followed up at 30 days, up to 2 years for response, and up to 5 years for survival. ;
