Primary Outcome Measures:

  • Number of patients with TCR V beta oligoclonality at diagnosis [ Time Frame: 96 months ] [ Designated as safety issue: No ]
  • Immunophenotype of patients with oligoclonal T-cell expansion [ Time Frame: 96 months ] [ Designated as safety issue: No ]

  • Number of patients with HLA-DR15 antigen expression and molecular response as compared to number of patients with other HLA-DR antigens and molecular response [ Time Frame: 96 months ] [ Designated as safety issue: No ]
  • Overall survival [ Time Frame: 96 months ] [ Designated as safety issue: No ]
  • Failure-free survival [ Time Frame: 96 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 125
Study Start Date: January 2007

Detailed Description:

OBJECTIVES:

Primary

  • To evaluate the value of TCR V beta repertoire analysis for the determination of autoimmunity in refractory cytopenia (RC).
  • To evaluate which immunophenotypic hematopoietic subclones are associated with oligoclonal T-cell expansion in RC.
  • To evaluate the presence of paroxysmal nocturnal hemoglobinuria (PNH) clones in RC.

Secondary

  • To compare the molecular response with the hematologic response in patients with RC after treatment with immunosuppressive therapy (IST).
  • To compare the molecular response with human leukocyte histocompatability antigen (HLA) expression in patients with RC after treatment with IST.

OUTLINE: This is an open-label, multicenter, nonrandomized, prospective study.

Patients undergo biopsy, bone marrow, and blood sample collection periodically for immunological studies. Samples are analyzed for TCR V beta repertoire and paroxysmal nocturnal hemoglobinuria (PNH) clone analysis via PCR heteroduplex analysis and immunophenotyping of CD14, CD16 , CD55, CD59, and CD24 expression via flow cytometry.
