A Study to Compare JL14002 to Lucentis® in Subjects With Wet Age-related Macular Degeneration (wAMD)

A Randomized, Double-masked, Multicenter, Parallel Group, Phase 3 Clinical Trial to Compare the Efficacy and Safety of JL14002 Monoclonal Antibody Injection Versus Ranibizumab Injection in Patients With Neovascular (Wet) Age-Related Macular Degeneration (wAMD)

This is a randomised, double-masked, parallel group, multicentre study to evaluate the efficacy and safety of JL14002 compared to Lucentis® in subjects with wAMD.

Study Overview

• Status: Completed
• Conditions: Wet Age-related Macular Degeneration
• Intervention / Treatment: Drug: JL14002 monoclonal antibody(Fixed dosing regimen); Drug: JL14002 monoclonal antibody(PRN); Drug: Ranibizumab(Fixed dosing regimen); Drug: Ranibizumab(PRN)

Detailed Description

Subjects will be randomised in a 2:1:1 ratio into the JL14002 Experimental Arm, Active Comparator Arm 1, and Active Comparator Arm 2. During the first 12 weeks, all subjects will receive fixed dosing at intervals of every 4 weeks (0.5 mg per dose), with a total of three consecutive doses. Subjects in the JL14002 experimental arm will receive JL14002 monoclonal antibody injection, while those in active comparator arm 1 and active comparator arm 2 will receive ranibizumab injection. Starting from week 12, all subjects will transition to a pro re nata (PRN) dosing regimen. Based on the PRN criteria assessed by the investigator, subjects in the JL14002 experimental arm and active comparator arm 1 will receive JL14002 monoclonal antibody injection as needed, while subjects in active comparator arm 2 will receive ranibizumab injection as needed. All subjects will be required to return to the study site every 4 weeks for safety and efficacy assessments.

Description

Inclusion Criteria:

Diagnosis of wet Age-related Macular Degeneration (wAMD) with active disease at screening, defined by the presence of ≥1 of the following macular lesions:a) Intraretinal fluid; b) Intraretinal lipid exudation or subretinal fluid; c) Subretinal fluid; d) Subretinal hemorrhage; e) Retinal pigment epithelial detachment (PED).
2. Best Corrected Visual Acuity (BCVA) score between 75 and 24 letters (inclusive) as measured by ETDRS chart at screening (Snellen equivalent: 20/32 to 20/320).

Exclusion Criteria:

1. Previous treatment with photodynamic therapy (PDT) or any combination therapy involving PDT in either eye.
