Study Details

Study Description

Brief Summary

This Phase 2 study is conducted to investigate the safety and efficacy of runcaciguat in the treatment of diabetic retinopathy. To assess efficacy, the retinal morphology will be investigated by 7-field color fundus photography for central assessment of the diabetic retinopathy severity score, or DRSS. Two-step DRSS improvement at 24 weeks of treatment will be the primary efficacy endpoint. DRSS assessments are repeated after completion of 48 weeks of treatment. In addition, vision threatening complications will be recorded throughout the study and assessed as secondary efficacy endpoint.

  2. Vision threatening complications at 48 weeks of treatment in the study eye [At 48 weeks]

  3. DRSS improvement ≥2 steps at 48 weeks of treatment in the study eye [At 48 weeks]

    DRSS (Diabetic Retinopathy Severity Scale) will be graded centrally.
