Evaluating of the Safety, Pharmacokinetics and Pharmacodynamics of QL1205 and Lucentis® in Patients With Wet AMD

Study Overview
=================
Brief Summary
-----------------
This is a randomized, double-blind, two-group parallel, positive-controlled clinical Phase I trial comparing the safety, pharmacokinetics and pharmacodynamics of QL1205 and Lucentis® in patients with wet age-related macular degeneration.

Detailed Description
-----------------
This is a phase I, randomized, double-blind, two-group parallel, positive-controlled clinical trial at four centers. The primary objective is to assess the initial clinical safety of intravitreal injection of QL1205 or Lucentis® in patients with wet age-related macular degeneration (wet-AMD). The secondary objective are to assess the initial clinical effectiveness and pharmacokinetic characteristics of intravitreal injection of QL1205 or Lucentis® in patients with wet age-related macular degeneration (wet-AMD). Subjects would sequentially enrolled according to the protocol in one of two cohorts.Subjects would receive a single 0.5mg of QL1205 or Lucentis® once a month for three months through vitreous injection.

Eligibility Criteria
-----------------
Inclusion Criteria: Sign the informed consent form, and willing to receive follow-up according to the time stipulated by the trial; Aged ≥50 years or ≤80 years, male or female (including the boundary value); The target eye must meet the following requirements; Has newly occurring or relapsed subfoveal and perifoveal active choroidal neovascularization (CNV) lesions secondary to AMD; The total area of all types of lesions is ≤30 mm2(the area of 12 optic discs); The best corrected visual acuity is 78-19 letters (equivalent to Snellen visual acuity of 20/32 to 20/400); No refractive media opacity or myosis affecting fundus examination; The best corrected visual acuity of the subject's non-target eye is ≥19 letters (equivalent to Snellen visual acuity of 20/400). Note: If the subject's eyes both meet the inclusion criteria, the investigator will determines the target eye from a medical point of view. Exclusion Criteria: Patients with any of the following eye conditions: The investigator judges that the target eye is currently suffering or used to suffer from non-exudative AMD disease affecting macular detection, or ocular diseases affecting central visual acuity (including central venous obstruction, diabetic retinopathy, uveitis, vascular striation, pathological myopia, retinal detachment, macular hole, etc.); The target eye's CNV is secondary to diseases other than AMD, such as trauma, pathological myopia,etc.; Either eye has previously received drug treatment for CNV (e.g., Lucentis, Avastin, Eylea, Composin, Acaconac, triamcinolone, steroids, etc.) The target eye has subretinal hemorrhage, and hemorrhagic area is ≥ 50% of the total area of the lesion, or the subfoveal bleeding area is ≥ 1 optic disc area;
