A Study of ASKG712 in Patients With Diabetic Macular Edema

Phase 1
Not yet recruiting
Conditions
Diabetic Macular Edema
Interventions
Biological: ASKG712
Registration Number
NCT05940428
Lead Sponsor
AskGene Pharma, Inc.
Brief 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).

Detailed 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.
