General information about the trial
|
|||
Main objective of the trial |
The primary aim of this pilot study was to show whether intravitreal Iluvien® therapy has an influence on the inflammatory factor IL-6, which, in conjunction with growth factors, is significantly involved in the development of diabetic macular edema. In a possible main study based on this, the presumed influence of the Iluvien® therapy on the inflammatory factor IL-6 is then to be more precisely determined and statistically analyzed with a larger sample over a longer period of time.

Adverse events information
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Timeframe for reporting adverse events |
Recording of new adverse events began at the baseline visit (T0, start of treatment) and ended with the completion of the last examination of the patient (T4). AEs that persisted at the end of the study were followed up for up to 28 days after T4 visit.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Adverse event reporting additional description |
In addition, if available, AEs that occurred before the start of treatment and AEs after the end of study (date of visit T4), were listed.
