Clinical Trial Summary

This multicenter, non-randomized, open-label, multiple-dose-escalation and dose-expansion study will investigate the safety, tolerability, pharmacokinetics and efficacy of ASKG712 following intravitreal administration in patients with diabetic macular edema (DME).

Description:

The Part 1 of study is a multicenter, open-label, sequentially, multiple-dose-escalation study to evaluate the safety, tolerability, pharmacokinetics and efficacy of ASKG712 in patients with DME. Patients will be sequentially enrolled into four different dose-level cohorts following accelerated titration combined with the traditional "3+3" design.

The Part 2 of study is a multicenter, open-label, sequentially, dose-expansion study to evaluate the safety, tolerability, pharmacokinetics and efficacy of ASKG712 in patients with DME.

Eligibility

Inclusion Criteria:

1. Documented diagnosis of diabetes mellitus (Type 1 or Type 2)

2. Hemoglobin A1c of less than or equal to 12%

3. For women of childbearing potential: agreement to use acceptable contraceptive methods during the treatment period and for at least 90 days after the final dose of study treatment

4. Ability and willingness to undertake all scheduled visits and assessments

5. Macular thickening secondary to DME involving the center of the fovea

6. Decreased visual acuity attributable primarily to DME

Exclusion Criteria:

2. Diseases that affect intravenous injection and venous blood sampling

3. Uncontrolled blood pressure

4. Systemic autoimmune diseases

5. Previous anti-VEGF drug treatment

7. Any uncontrolled clinical disorders

8. Any current ocular condition which, in the opinion of the investigator, is currently causing or could be expected to contribute to irreversible vision loss due to a cause other than DME in the study eye

9. History of intraocular or periocular corticosteroid treatment in the study eye

10. Uncontrolled previous or current glaucoma in the study eye

11. Previous intraocular operations in the study eye

12. Active intraocular or periocular infection or active intraocular inflammation in the study eye

13. History of uveitis in either eye
