pk, pd, safety and immunogenicity study of erythropoietin of incepta pharmaceuticals ltd with eprex (janssen-cilag).

Conditions: Healthy

Summary: erythropoietin is a glycoprotein which stimulates red blood cell production. it is produced in the kidney and stimulates the division and differentiation of committed erythroid progenitors in the bone marrow. erythropoietin, a 165 amino acid glycoprotein manufactured by recombinant dna technology, has the same biological effects as endogenous erythropoietin. erythropoietin binds to the surface receptor of erythroid precursor cells and activates signal transduction pathways that interfere with apoptosis and stimulates erythroid cell proliferation. recombinant human erythropoietin is a substitute for the deficiency observed in ckd, therapy of anemia often involves many other issues such as anemia in patients with non-myeloid malignancies where anemia is due to the effect of concomitantly administered chemotherapy, anemic patients (hemoglobin \> 10 to \< 13 g/dl) scheduled to undergo elective, noncardiac, nonvascular surgery to reduce the need for allogeneic blood transfusions, anemia related to therapy with zidovudine in hiv-infected patients are also needed to be considered in order to effectively correct anemia, reduce costs and minimize side effects.

in this study, 56 healthy adult volunteers will participate in a randomized, double-blinded, balanced, two-treatment, two-period, two-sequence, single-dose crossover trial. each subject will receive a single subcutaneous injection of either erythropoietin 4000 iu manufactured by incepta pharmaceuticals ltd (test product) or eprex 4000 iu manufactured by janssen-cilag ltd (reference product) under fasting conditions, with a 28-day washout period between doses. the primary aim of the study is to compare the pharmacokinetic and pharmacodynamic profiles of the two products. additionally, the study will assess immunogenicity by measuring serum anti-drug antibodies (ada) and evaluate the safety of both formulations throughout the study duration.
