Arms Assigned Interventions
Experimental: 1 Drug: Darbepoetin alfa

Dosage form: injection (to store between 2 and 8 °C). Dosage: various dosages are available (10, 15, 20, 30, 40, 50, 60, 80, 100, 150 or 300 µg/ml).

Frequency: every week for 2 months: 8 injections

Other Name: Darbepoetin alfa

Detailed 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.

Criteria

Inclusion Criteria:

  • Male and female aged 40-75 years
  • Diagnosis of a moderate to very severe COPD (stage II, III or IV according to GOLD criteria)
  • A ratio of post-bronchodilator FEV1 to forced vital capacity (FVC) < 70%
  • A FEV1 < 80% of the predicted value
  • Hemoglobin level less than 12 g/dL

Exclusion Criteria:

  • Hemorrhagic anemia
  • Iron deficiency anemia (ferritin < 30 ng/ml)
  • Folate and Vitamin B12 deficiency anemia
  • Myelodysplastic Syndrome
  • Chronic disease associated with anemia: renal insufficiency, inflammatory disease, neoplastic disease, left ventricular insufficiency (ejection fraction < 40%)

  • Acute exacerbation of COPD within the last 4 weeks
  • History of thromboembolic disease
  • Contraindications for cardiopulmonary exercise testing
  • Contraindications for darbepoetin alfa treatment: uncontrolled arterial hypertension or hypersensitivity reaction to darbepoetin alfa
