Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

    • Presence of active intraocular or periocular infection or inflammation;

  2. Ocular treatment:

    • Anti-VEGF or anti-complement therapy in the study eye within 90 days prior to baseline;
    • Fundus laser photo-coagulation in the study eye within 90 days prior to baseline;
    • Photodynamic Therapy (PDT) in the study eye within 90 days prior to baseline;
    • History of vitreoretinal surgery, penetrating keratoplasty in the study eye;

  3. General condition or treatment:

    • Uncontrolled hypertension (defined as systolic blood pressure > 160 mmHg or diastolic blood pressure > 100 mmHg after standard treatment);
    • HbA1c > 8% within 28 days prior to baseline; Systemic anti-VEGF drug and anti-complement drug therapy within 90 days prior to baseline;
    • History of hypersensitivity to any component of the test article, control article, or clinically relevant sensitivity to fluorescein dye, povidone-iodine;
    • Pregnant or lactating women; Inappropriate for the study (e.g., substance abuse, inability or unwillingness to follow the trial protocol), as judged by the investig.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean change from baseline in Best corrected visual acuity ( BCVA ) in the study eye.
Time Frame: At week 44, 48, 52
Change from Baseline in BCVA as measured by Early Treatment Diabetic Retinopathy Study (ETDRS) letter score at week 44, 48, 52.
At week 44, 48, 52

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The proportion of participants with absence intraretinal fluid (IRF) and absence subretinal fluid (SRF) in the fovea at Week 16
Time Frame: At week 16
The intraretinal fluid and subretinal fluid is measured by optical coherence tomography (OCT) in the central subfield(center 1 millimeter)
At week 16
Change from baseline in BCVA at Week 52 and 100
Time Frame: Upto Week 100
Best corrected visual acuity (BCVA) was measured on early treatment diabetic retinopathy study(ETDRS) chart at a starting distance of 4 meters. The BCVAletter score ranges from 0 to 100(best score), and a gain in BCVA from baseline indicates an improvement in visual acuity.
Upto Week 100
Change from baseline in central subfield thickness (CST) measured by optical coherence tomography (OCT) at Week 52 and 100
Time Frame: Upto Week 100
Central subfield thickness was defined as the distance between the internal limiting member and the Bruch's member using OCT, as assessed by the central reading center.
Upto Week 100
Change from baseline in area of CNV on fundus fluorescence angiography (FFA) at Week 52 and 100
Time Frame: Upto Week 100
the area of the choroidal neovascularization lesion in the study eye was measured by a central reading center using FFA
Upto Week 100
Proportion of participants on a q8W, q12W, and q16W treatment intervals at Week 52 and 100
Time Frame: Upto Week 100
Percentages are based on number of participants randomized to the IBI302 group who have not discontinued the study at week 52 and 100. the treatment interval at a givven visit is defined as the treatment interval decision followed at that visit.
Upto Week 100
Incidence, relatedness to the study drug and severity of ocular and Non-ocular adverse events (AE), treatment emergent adverse events (TEAE) and serious adverse events (SAE).
Time Frame: Upto Week 100
All AEs were recorded and the investigator made an assessment of seriousness,severity, and causality of each AE.
Upto Week 100
