Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This Phase 3 study will evaluate the efficacy and safety of KSI-301 compared to aflibercept, in participants with neovascular (wet) age-related macular degeneration (wAMD)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 3, prospective, randomized, double-masked, two-arm, multi-center non-inferiority study evaluating the efficacy and safety of repeated intravitreal dosing of KSI-301 5 mg in participants with visual impairment due to treatment-naïve neovascular (wet) age-related macular degeneration (wAMD)

The primary endpoint will be assessed as an average of Weeks 40, 44, and 48; additional secondary endpoints for efficacy will be assessed by visit over time

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants will be randomized 1:1 into one of two treatment arms: KSI-301 or aflibercept.
Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Caregivers Outcome Assessors
For masking purposes, sham injections will be administered at every monthly visit if an active treatment is not administered. To preserve masking, two investigators are required for this study. The masked Investigator will be responsible for the examinations and safety assessments. The unmasked Investigator will perform the injections and post-treatment assessments.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

KSI-301 (Treatment Group A)

Intravitreal injection of KSI-301 (5 mg) at Day 1 once every 4 weeks via intravitreal injection through Week 44.

Group Type EXPERIMENTAL

KSI-301

Intervention Type DRUG

Intravitreal Injection

Aflibercept (Treatment Group B)

Intravitreal injection of aflibercept (2 mg) once every 4 weeks for 3 monthly doses followed by intravitreal injection of aflibercept (2 mg) once every 8 weeks from Week 16 to Week 44. Sham injections will be administered at each monthly visit where an active treatment is not administered.

Group Type ACTIVE_COMPARATOR

Aflibercept

Intervention Type DRUG

Intravitreal Injection

Sham Procedure

Intervention Type OTHER

The sham is a procedure that mimics an intravitreal injection. It involves pressing the blunt end of an empty syringe (without a needle) against the anesthetized eye. It will be administered to participants in both treatments arms at applicable visits to maintain masking.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Signed informed consent prior to participation in the study.
* Treatment-naïve choroidal neovascularization (CNV) secondary to AMD.
* BCVA ETDRS score between 83 and 25 letters, inclusive, in the Study Eye.
* Decrease in vision in the Study Eye determined by the Investigator to be primarily the result of wAMD.

Exclusion Criteria

* BCVA of hand motion or worse in the non-Study Eye or non-physical presence of a non-Study Eye (i.e., monocular).
* Active or suspected ocular or periocular infection or inflammation.
* CNV secondary to other causes in the Study Eye.
* Any history or evidence of a concurrent ocular condition present in the Study Eye, that in the opinion of the Investigator could require either medical or surgical intervention or affect macular edema or alter visual acuity during the study.
* Uncontrolled glaucoma in the Study Eye.
* Significant media opacities, including cataract, in the Study Eye that might interfere with visual acuity, assessment of safety, OCT or fundus photography.
* Cataract in the Study Eye that in the judgment of the Investigator is expected to require surgical extraction within 12 months of screening.
* Women who are pregnant or lactating or intending to become pregnant during the study.
* Recent history (within the 6 months prior to screening) of myocardial infarction, stroke, transient ischemic attack, acute congestive heart failure or any acute coronary event.
* History of a medical condition that, in the judgment of the Investigator, would preclude scheduled study visits, completion of the study, or a safe administration of investigational product.
* Uncontrolled blood pressure defined as a systolic value ≥180 mmHg or diastolic value ≥100 mmHg while at rest.
