The Study of CU06-1004 in Patients With Diabetic Macular Edema (DME)
Study Details
Study Description
Brief Summary
This phase 2a trial is a randomized, open-label, parallel-group study in approximately 60 patients with DME to evaluate the efficacy and safety of CU06-1004 orally administered once daily for 12 weeks. The study will have a 1:1:1 randomization (CU06-1004 100mg: CU06-1004 200mg: CU06-1004 300mg).

Outcome Measures
Primary Outcome Measures
- The change of central subfield thickness (CST) [Baseline and 12 weeks]
Change in CST in the study eye assessed by SD-OCT at Week 12 compared to baseline
- To determine the optimal doses [12 weeks]
The 1:1:1 randomization is fitting for the study objective to determine the optimal doses for a phase 2b study.
Secondary Outcome Measures
- The change of central subfield thickness (CST) [Baseline, 4 weeks and 8 weeks]
Change in CST in the study eye assessed by SD-OCT Weeks 4 and 8 compared to baseline
- The change of all other subfield thickness [Baseline, 4 weeks, 8 weeks and 12 weeks]
Change in all other subfield thickness (Nasal, temporal, superior and inferior) in the study eye assessed by SD-OCT at Weeks 4, 8, and 12 compared to baseline
- The change of early treatment diabetic retinopathy study (ETDRS) best-corrected visual acuity (BCVA) letter score [Baseline, 4 weeks, 8 weeks and 12 weeks]
Change in ETDRS BCVA letter score in the study eye at Weeks 4, 8, and 12 compared to baseline
- Change in diabetic retinopathy severity scale (DRSS) [Baseline and 12 weeks]
Change in DRSS in the study eye at Weeks 12 compared to baseline
- The change of blood biomarkers [Baseline and 12 weeks]
Change in blood biomarker (TNF-alpha, IL-1 beta, IL-6) at Week 12 compared to baseline
- Number and severity of treatment emergent adverse events (TEAEs) [Baseline and 12 weeks]
Number and severity of TEAEs up to Week 12 compared to baseline
