Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
OBJECTIVES: I. Determine whether arginine butyrate with or without epoetin alfa can stimulate gamma-globin chain production to a degree that decreases anemia and results in hematologic improvement in patients with thalassemia intermedia. II. Determine whether a proportional increase in gamma-globin synthesis and mRNA and an improvement in nonalfa and alfaglobin chain imbalance by at least 10% over baseline correlate with improved hematologic response in these patients when treated with this regimen. III. Determine whether a decrease in hemolysis, as assayed by a decrease in LDH, compared to baseline levels correlates with improved hematologic response in these patients when treated with this regimen. IV. Determine whether any particular genotypes are more responsive than others to this therapy in these patients. V. Determine whether baseline epoetin alfa levels, gender, and/or baseline reticulocyte counts (or percent circulating nucleated erythroblasts) correlate with improved hematologic response in these patients when treated with this regimen.
