Clinical Trial Summary

this study will compare the efficacy and safety of HLX04-O administered by IVT with ranibizumab in patients with active CNV secondary to AMD.

Description:

This is a Phase 3, multicenter, randomized double masked active controlled study to compare the efficacy and safety of HLX04-O administered by IVT with ranibizumab in patients with active CNV secondary to AMD. The study will be conducted in approximately 60 sites in China.

Either HLX04-O (1.25 mg) IVT or ranibizumab (0.5 mg) IVT will be administered at a 4-week interval for 1 year (12 cycles).

2. Women or men aged =50 years when signing the ICF.

3. Newly diagnosed, untreated, active subfoveal or juxtafoveal CNV lesions secondary to AMD in the study eye. (Active CNV was defined as leakage on FA and subretinal or intraretinal fluid on OCT with confirmation of the reading center during screening).

4. The total lesion area (including hemorrhage, scar and neovascularization) of the study eye =12 disc area (DA) with confirmation of the reading center before randomization a.

5. The BCVA letters between 24 and 73, inclusive, in the study eye, using Early Treatment Diabetic Retinopathy Study (ETDRS) charts.

6. Clear ocular media and adequate pupillary dilatation to allow acquisition of good quality retinal images to confirm the diagnosis.

7. Participants' fellow (non-study) eye must have had a BCVA of 24 letters or better.

Exclusion Criteria:

1. Macular-related retinal pigment epithelial tears in the study eye; scar, fibrosis or atrophy involving the fovea, or CNV due to other causes in the study eye (e.g., ocular histoplasmosis, trauma, or pathological myopia etc.) with confirmation of the reading center.

2. The fellow (nonstudy) eye needs anti-VEGF IVT injection (e.g. CNV due to wAMD, trauma, pathological myopia, retina vein occlusion, diabetic macular edema, etc) in the next 3 months after randomization, in the investigator's judgment.

3. Active or recent (within 1 month prior to dose 1) intraocular, extraocular or periocular infection (including conjunctivitis, keratitis, scleritis or endophthalmitis), or history of idiopathic or autoimmune-associated uveitis in either eye.

4. Vitreous hemorrhage in the study eye within 3 months prior to dose 1.

Effective contraceptive methods include bilateral tubal ligation, male sterilization, established, proper use of hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices (IUDs), and copper IUDs.

17. In the Investigator's judgment, there is evidence of a disease or condition that contraindicates the use an investigational drug or that might affect interpretation of the results of the study or render the participant at high risk for treatment complications (e.g. stroke or myocardial infarction within 6 months prior todose1, uncontrolled hypertension (systolic blood pressure=160 mmHg, or diastolic blood pressure =100 mmHg), etc.).

18. Uncontrolled diabetes (defined as HbA1c>10.0%).

19. Alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) is more than twice the upper limit of normal (ULN), and/or serum creatinine is 1.2 times more than the ULN, and is clinically significant in the opinion of the Investigator.

20. Abnormal coagulation function(prothrombin time = 3 seconds over ULN, activated partial thromboplastin time = 10 seconds over ULN)

21. Active disseminated intravascular coagulation and obvious bleeding tendency within 3 months prior to dose 1.

22. Evidence of significant uncontrolled concomitant diseases such as cardiovascular diseases, nervous system diseases, respiratory system diseases, urinary system diseases, digestive system diseases and endocrine diseases.

23. Current treatment for active systemic infection, or history of recurrent serious infections.

24. Known active or suspected autoimmune diseases, requiring systemic immunosuppressive therapy.

25. Positive for syphilis screening test or positive for human immunodeficiency virus (HIV) screening test.

26. Known allergy to any component of the study intervention or history of allergy to fluorescein or indocyanine green, any anesthetics or antimicrobial agents used during the course of the study.

27. In the Investigator's judgment, other conditions considered not amenable to this study.

28. Participant who has been diagnosed to be COVID-19 or who has received COVID-19 vaccine within 1 month prior to dose 1.

Other protocol defined inclusion and exclusion criteria may apply.
