Primary Outcome Measures:
  • Incidence rate of adverse event [ Time Frame: up to 12 months ]
    To evaluate the safety of multiple intravitreal injection of KH902 to treat DME.


Secondary Outcome Measures:
  • Change from Baseline in BCVA [ Time Frame: at the end of month 3 and the end of month 12 ]

Enrollment: 20
Study Start Date: April 2010
Study Completion Date: October 2012
Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Group A
Patients will receive an intravitreal injection of 0.5mg KH902 in the study eye at the first month, following the fixed injection, patients will continue to receive injection of KH902 at the same dose on an as needed (PRN) dosing schedule based upon the monthly physician assessment of the need for re-treatment in accordance with pre-specified criteria.
Biological: KH902
Intravitreal injection of 0.5mg/eye/time KH902
Experimental: Group B
Patients will receive continuously monthly intravitreal injections of 0.5 mg KH902 for 3 times in the study eye; following the initial 3-month fixed-dosing phase of the trial, patients will continue to receive injection of KH902 at the same dose on an as needed (PRN) dosing schedule based upon the monthly physician assessment of the need for re-treatment in accordance with pre-specified criteria.
Biological: KH902
Intravitreal injection of 0.5mg/eye/time KH902

Detailed Description:

With improvement of our living standard, patients who suffered from Diabetes become more and more. As the investigators know, Diabetes can induce many ocular diseases leading to vision loss. And according to observations, DME is diagnosed as one main cause of vision loss in the patients with Diabetes.

As the results of many studies conducted previously, anti-VEGF drugs and anti-VEGF treatments show its effect and safety not only in treating AMD, but also in patients with DME. The new drug Recombinant Human VEGF Receptor-Fc Fusion Protein (KH902) is a gene fusion protein. The previous clinical trials of KH902 show that KH902 is effective and safe in inhibiting the growth, migration, pullulation of vascular endothelial cells and neovascularization induced by VEGF. Due to these positive results, the investigators prepare to conduct a clinical trial to assess the safety and efficacy with intravitreal injection of KH902 in patients with DME.
