Brief Summary
RATIONALE: Immunosuppressive therapies, such as anti-thymocyte globulin and cyclosporine, may improve bone marrow function and increase blood cell counts. PURPOSE: This phase II trial is studying how well giving anti-thymocyte globulin together with cyclosporine as first-line therapy works in treating patients with severe aplastic anemia.

Outcome Measures
Primary Outcomes (1)
Patients Treated With Rabbit Antithymocyte Globulin (r-ATG/Thymoglobulin) and Cyclosporine (CsA) Achieving at Least a Partial Remission (PR) at 6 Months
Patients will be classified as responders if they have transfusion independence and meet two of the following three criteria: ANC greater than 500/mm3; platelet count greater than 20,000/mm3; and reticulocyte count greater than 40,000/mm3. Transfusion independence is defined as no need for transfusions for one month prior to response assessment.
At 6 months
Study Arms (1)
rATG + Cyclosporine
EXPERIMENTALPatients receive anti-thymocyte globulin IV daily over 4-24 hours on days 1-5. Beginning on day 6, patients receive oral cyclosporine twice daily for 6 months followed by a taper. Treatment continues in the absence of disease progression or unacceptable toxicity
Interventions
Given orally
Given IV
Eligibility Criteria
You may qualify if:
- All patients with sAA as defined by Camitta who are candidates for IS therapy; these criteria include bone marrow cellularity \< 25% or 25-50% with \< 30% of hematopoietic cells; it should also have two of the following three parameters: peripheral blood neutrophils \< 0.5 x 10\^9/L, platelets \< 20 x 10\^9/L and reticulocytes \< 60 x 10\^9/L in anemic patients
- If cytogenetic testing has been done, it should show normal karyotype or be not informative
- Patients should be either unwilling or otherwise ineligible (age, comorbidities, lack of donor) for bone marrow transplantation as a therapeutic modality
- Not previously treated with ATG for sAA
- Patients must have ECOG performance status of 0, 1, or 2
- Vitamin B12 and folic acid deficiency must be ruled out by measurement of serum levels
- Patients must have had a bone marrow biopsy examination in the three months prior to enrolling in the study
- Must be able to provide informed consent
- Systemic and other hematologic causes of pancytopenia, based on clinical presentation, must have been ruled out
You may not qualify if:
- Patients with clinically evident congestive heart failure, serious cardiac arrhythmias; symptoms of coronary artery disease must be cleared by cardiology prior to therapy
- Patients who have had chemotherapy, radiotherapy, or immunotherapy or other investigational drug use within 3 weeks prior to study entry
- Pregnant women
- All females of childbearing potential must have a blood test or urine study within two weeks prior to induction registration to rule out pregnancy
- Women of childbearing potential are strongly advised to use an accepted and effective method of contraception
- Patients who have medical, psychological, or social conditions that may interfere with the patient's participation in the study or evaluation of the study results
