General information about the trial
|
|||
Main objective of the trial |
Primary objectives:
Evaluation of efficacy of the treatment with intravitreal administered injections of Bevacizumab (Avastin®) compared with Triamcinolone (Volon A®) in patients with clinical significant diabetic macular edema. The main focus of the assessments of efficacy is:
1. The percent change in macular edema measured with standard optical coherence tomography (OCT).
2. The absolute change in visual acuity analyzed by standardized charts according to the protocol used in the Early Retreatment in Diabetic Retinopathy Study (ETDRS).
|
||
Protection of trial subjects |
The trial followed the tenets of the Helsinki Declaration. Before study inclusion, the interventional study design and examinations for scientific purposes were explained to each patient in a personal interview and informed consent was obtained. Contact information of the study team was provided. Intravitreal injections were administered in local anaesthesia. Lubricant eye drops were used against eye-discomfort after the injection. Patients

Recruitment

Recruitment details |
Study patients were recruited between 2007 and 2014 at the outpatient clinic of the Department of Ophthalmology, Medical University Vienna, Austria. | |||||||||||||||
Pre-assignment
|
||||||||||||||||
Screening details |
Only one eye of each patient could be included in the study. Eligibility criteria were patients aged ≥18 years with type 1 or 2 diabetes, a best-corrected visual acuity (BCVA) between 20/25 and 20/400 (Snellen equivalent) and a macula center involving DME with a CRT of more than 300 μm measured with spectral domain (SD) OCT. | |||||||||||||||

There were two teams of study investigators: Investigators examining the patients were masked to treatment arm. Investigators applying the medication were masked to study results. Since Triamcinolone was injected no more than every three months sham injections were given intermittend to maintain patient masking.

Notes [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same. Justification: The first period was a comparison between bevacizumab and triamcinolone. The second period was a comparison between ranibizumab and triamcinolone. Subjects of the first period did not participate in the second period. |
