Evaluation of Retinal Changes in Systemic Darbepoetin Alpha Treatment in Patients With Diabetes Mellitus (EPOinDR)
This study is currently recruiting participants.
Verified by Medical University of Vienna, May 2008
Sponsors and Collaborators: Medical University of Vienna

Information provided by: Medical University of Vienna
ClinicalTrials.gov Identifier: NCT00704652
  Purpose

The purpose of this study is to determine whether systemic administration of darbepoetin alpha results in the progression or regression of diabetic macular edema.

Official Title: Evaluation of Functional and Morphological Retinal Changes in the Course of Systemic Aranesp Treatment in Patients With Diabetes Mellitus

Further study details as provided by Medical University of Vienna:

Primary Outcome Measures:
  • Morphologic changes in the retina detected by HD-OCT following darbepoetin alpha therapy compared to control patients [ Time Frame: 9 month ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Functional improvement in best corrected visual acuity (BCVA) and microperimetry following darbepoetin alpha therapy compared to control patients. [ Time Frame: 9 month ] [ Designated as safety issue: No ]
  • Changes in anterior chamber flare and cell count following darbepoetin alpha therapy compared to control patients. [ Time Frame: 9 month ] [ Designated as safety issue: No ]
  • Changes in the fundus image and fluorescein angiographic features following darbepoetin alpha therapy compared to control patients. [ Time Frame: 9 month ] [ Designated as safety issue: No ]
  • Changes in blood count, chemistry, Astrup and blood clotting following darbepoetin alpha therapy compared to control patients. [ Time Frame: 9 month ] [ Designated as safety issue: No ]

Biospecimen Retention:   None Retained

Biospecimen Description:

Estimated Enrollment: 40
Study Start Date: May 2008
Estimated Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts
A
Diabetic patients suffering from renal insufficiency with stable haemoglobin levels (receiving no EPO supplementation)
B
Diabetic patients with renal insufficiency and in need of recombinant human EPO (darbepoetin alfa) substitution because of inadequate erythropoiesis. In both groups the target haemoglobin level is 10-12 gHb/ml, all treatment is performed according to label.

  Eligibility

Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

Diabetic patients with min. Grade 2 renal insufficiency, and in Group B with anemia that is to be treated with systemic ESA therapy.

Criteria

Inclusion Criteria:

Group B:

  • Inability to communicate in German or English
  • Dementia; inability to follow commands
  • Epilepsy
