Study of Erythropoietin to Treat Anemia Complicating Chronic Obstructive Pulmonary Disease

2014-07-24 14:19:31 | BioPortfolio

Summary

The purpose of this study is to determine the impact of erythropoietin treatment of anemia on exercise capacity of patients with chronic obstructive pulmonary disease (COPD).

Description

The development of anemia in patients with chronic obstructive pulmonary disease (COPD) is now taken as a predictor of increased morbidity and mortality. Preliminary data from patients investigated in our department indicate a negative correlation between anemia severity and 6-minute walking distance. Our working hypothesis is that hemoglobin level correction by erythropoietin therapy will improve the effort capacity of patients with COPD and anemia. Our objective is to conduct a pilot study of the efficacy of darbepoetin alfa.

The study will include about 15 patients with COPD recruited at three pulmonology centers based on two selection criteria: COPD stage II or III or IV according to GOLD criteria and hemoglobin level less than 12 g/dL. Effort capacity will be evaluated chiefly by performing a 6-minute walking test and by measuring VO2 at maximum exertion on a bicycle ergometer with increasing loads. Darbepoetin alfa will be given for 2 months. If the hemoglobin increase is less than 1 g/dL after 1 month, the dosage will be increased by 25%.

Effort parameters will be measured at baseline and after 1 and 2 months of treatment. Among secondary objectives, we will evaluate functional ergospirometric parameters and laboratory tests for inflammation. Total study duration will not exceed 18 months.

A recombinant protein which stimulates ERYTHROPOIESIS used to treat ANEMIA.

A recombinant alfa interferon consisting of 165 amino acids with arginine at positions 23 and 34. It is used extensively as an antiviral and antineoplastic agent.

A recombinant alfa interferon consisting of 165 amino acids with lysine at position 23 and histidine at position 34. It is used extensively as an antiviral and antineoplastic agent.

A recombinant alfa interferon consisting of 165 amino acid residues with arginine in position 23 and histidine in position 34. It is used extensively as an antiviral and antineoplastic agent.

This recombinant erythropoietin, a 165-amino acid glycoprotein (about 62% protein and 38% carbohydrate), regulates red blood cell production. Epoetin alfa is produced by Chinese hamster ovary cells into which the human erythropoietin gene has been inserted. (USP Dictionary of USAN and International Drug Names, 1996).
