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 in participants with moderately severe to severe non-proliferative diabetic retinopathy (NPDR).

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, sham-controlled, two-arm, multicenter study evaluating the efficacy and safety of repeated intravitreal dosing of KSI-301 5 mg in participants with moderately severe to severe non-proliferative diabetic retinopathy (NPDR).

The primary endpoint will be assessed at Week 48; additional secondary endpoints for efficacy will be assessed at Week 48, Week 96 and if applicable, over time.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

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

TREATMENT

Blinding Strategy

TRIPLE

Participants Caregivers Outcome Assessors
To preserve masking, 2 investigators are required for this study. The masked investigator will be responsible for 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): three initiating doses, and then every 24 weeks through Week 92

Group Type EXPERIMENTAL

KSI-301

Intervention Type DRUG

Intravitreal injection

Treatment Group B

Sham injection on the same schedule as Treatment Group A

Group Type SHAM_COMPARATOR

Sham injection

Intervention Type OTHER

The sham injection 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 is performed to maintain masking of the study.

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.
* Type 1 or 2 diabetes mellitus
* Moderately severe to severe NPDR in the Study Eye (DRSS levels 47 and 53 as determined by the reading center), in which pan-retinal photocoagulation (PRP) can be safely deferred for at least 6 months per the Investigator.
* BCVA ETDRS letter score in the Study Eye of ≥69 letters (approximate Snellen equivalent of 20/40 or better)
* HbA1c of ≤12%.

Exclusion Criteria

* Presence of center-involved DME in the Study Eye
* Prior PRP in the Study Eye.
* Current anterior segment neovascularization (ASNV), vitreous hemorrhage, or tractional retinal detachment in the Study Eye.
* Prior intravitreal anti-VEGF treatment in the Study Eye for DR or DME.
* Prior intravitreal or periocular steroid in the Study Eye for DR or DME.
* Prior use of an investigational intravitreal treatment for DR or DME 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 alter visual acuity during the study
* Active or suspected ocular or periocular infection or inflammation.
* Women who are pregnant or lactating or intending to become pregnant during the study.
* 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.
* 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.
* Uncontrolled blood pressure defined as a systolic value ≥ 180 mmHg or diastolic value ≥ 100 mmHg while at rest.
