  Purpose

This is a clinical research trial in which a novel preparatory regimen was developed for bone marrow transplant (BMT) which eliminates the primary obstacle to transplant, the lack of a matched sibling donor. It is believed this regimen is sufficiently efficacious and sufficiently gentle to apply to patients with sickle cell anemia and related disorders. It is proposed to characterize the efficacy and toxicity of this regimen in high risk patients with sickle cell anemia using criteria for patient selection that have been accepted in prior BMT trials in patients with sickle cell disease, specifically only the subset of patients whose prior clinical behavior indicates that they are at high risk for serious morbidity and early mortality. In addition, it is proposed to characterize the pathophysiology of a consistent febrile response seen in the haploidentical BMT regimen the investigators have developed at Thomas Jefferson University (TJU).

The primary goal of this study is to determine the response rate to a reduced intensity conditioning regimen which consists of fludarabine, cytarabine, low dose total body irradiation and cyclophosphamide in patients with severe sickle cell anemia.

Detailed Description:

Hemoglobinopathies, such as sickle cell disease and thalassemia major, constitute a group of genetic diseases associated with significant morbidity and premature death. In the 1970s, the mean survival of patients with sickle cell disease was 14.3 years. With improvements in medical practice, this has improved such that estimates are now into the third decade of life.

In patients with sickle cell disease, a single amino acid substitution in beta-hemoglobin causes erythrocytes to sickle in response to oxidative stress. The sequelae of this defect are vaso-occlusive crises, resulting in episodes of bony pain and infarction, acute chest syndrome, and strokes. Life long need for transfusion leads to complications including alloimmunization and iron overload. The latter condition is frequently associated with significant end-organ damage.

In recent years, new strategies in supportive care, such as the use of hydroxyurea to stimulate fetal hemoglobin production in patients with sickle cell anemia, have resulted in the amelioration of some of the devastating manifestations of this disease. However, this therapy does not benefit all patients, and there have been concerns about the possible risk of latent transformation to leukemia with prolonged use of this drug. Clearly, better treatment strategies are needed for this devastating group of diseases.

Patients with sickle cell anemia will be offered enrollment on a clinical trial of reduced intensity stem cell transplant. The transplant donors will be either HLA matched siblings or family members who are 50% matched for HLA. Patients will receive therapy in 2 steps.

For patients who are allo-immunized against the donor (patients who have made an immune response already against the donor's HLA type), there will be a desensitization process. This will be outpatient therapy and will include therapy with bortezomib on the 1st, 4th, 8th and 11th day of a 21 day cycle. This will be repeated for a second cycle, for a total of 8 doses of bortezomib over a 6 week period. In addition, they will receive rituximab on the 1st and 8th day of each cycle. These therapies are designed to decrease the subject's chance of rejecting the transplant, as it is known that patients with sickle cell anemia are likely to be heavily immunized against donors. For patients who have high levels of antibodies against the donors, a plasmapheresis procedure will be performed prior to admission as well. All patients will undergo red cell exchange prior to admission.

During the transplant admission, subjects will receive a "Two Step" chemotherapy and transplant regimen. The chemotherapy "first step" will be with fludarabine and cytarabine and a low dose of total body irradiation. This will be followed by the "first step" of the transplant graft - the donor lymphocytes. The "second step" of the chemotherapy will be two doses of cyclophosphamide. This will then be followed by the "second step" of the transplant graft - the stem cells.

Criteria

Inclusion Criteria:

Patient Selection:

i) Patients with sickle cell disease (sickle cell anemia, sickle cell-hemoglobin C disease, or sickle cell-β0-thalassemia) confirmed by hemoglobin electrophoresis.

ii) Patients should have one or more of the following:

  1. History of acute chest syndrome requiring recurrent hospitalization or exchange transfusion (Acute chest syndrome is defined as pulmonary infiltrate involving at least one complete lung segment, consistent with alveolar consolidation but not atelectasis, accompanied by chest pain, fever, cough, tachypnea or wheezing)
  2. History of nonhemorrhagic stroke or central nervous system event lasting longer than 24 hours
  3. Recurrent vaso-occlusive pain (≥5 episodes during the past two years) or recurrent priapism requiring hospitalization or visits to the emergency room or sickle cell day unit
  4. Sickle nephropathy (moderate or severe proteinuria or a glomerular filtration rate 30-50% of normal predicted value) with progression on ACE inhibitor therapy iii) Patient must have failed therapy with hydroxyurea, as HU as evidenced by at least 6 months of maximum HU dosage for sickle cell disease, i.e. dose escalation to a level which caused some minimal hematologic toxicity in terms of CBC values. Failure to respond must also be documented by no significant increase in subjects HbF levels at this maximally tolerated dosage.AND development/ persistence of items listed in (ii) Patients who are deemed not eligible for hydroxyurea by the primary hematologist will be considered eligible without having failed hydroxyurea. Non-eligibility for hydroxyurea therapy is based on:

(1) the diagnoses of SC disease and sickle cell-β0-thalassemia in which no clear evidence supports the use of hydroxyurea therapy and thus treatment with hydroxyurea is not considered the standard of care in these entities (2) the presence of high hemoglobin F levels in patients with sickle cell anemia and documented Hereditary Persistence of Fetal Hemoglobin (HPFH) in which hydroxyurea is not considered the standard of care (3) severe adverse reactions to hydroxyurea in patients with sickle cell anemia based on, but not limited to, count suppression, GI intolerance, and dermatomyositis Patient unwillingness to be compliant with hydroxyurea therapy is not an acceptable reason for non-eligibility iv) Patients must have an acceptable related donor

  1. who is matched at the HLA-A;B; C; DR loci (8 of 8 match) or mismatched for at most one locus (7 of 8 match) (well matched related donor
  2. who is mismatched at 2-4 alleles (haplo-identical) v) Patient age greater than 18 - 45 years vi) ECOG performance status 0-2/ Karnofsky 70-100% vii) Written informed consent obtained from the patient. viii) Transaminases <3X ULN; patients with transaminases greater than the ULN but less than 3XULN will be evaluated by the hepatology service and will undergo further imaging and biopsy as deemed necessary by hepatology. They will not be considered eligible unless cleared by hepatology.

Exclusion Criteria:

Patient Selection:

i) Pregnancy/ unwillingness to use adequate contraception during study period ii) Liver disease including

  1. Acute hepatitis (transaminases >3x normal value)
  2. Chronic hepatitis C
