Brief Summary:
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).
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Non-proliferative Diabetic Retinopathy | Drug: KSI-301 Other: Sham injection | Phase 3 |
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.
| Study Type : | Interventional (Clinical Trial) |
| Actual Enrollment : | 253 participants |
| Allocation: | Randomized |
| Intervention Model: | Parallel Assignment |
| Intervention Model Description: | Participants will be randomized 1:1 into one of two arms: KSI-301 or sham. |
| Masking: | Triple (Participant, Care Provider, Outcomes Assessor) |
| Masking Description: | 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. |
| Primary Purpose: | Treatment |
| Official Title: | A Prospective, Randomized, Double-masked, Sham-controlled, Multicenter, Two-arm, Phase 3 Study to Evaluate the Efficacy and Safety of Intravitreal KSI-301 in Participants With Moderately Severe to Severe Non-proliferative Diabetic Retinopathy (NPDR) |
| Actual Study Start Date : | August 30, 2021 |
| Estimated Primary Completion Date : | November 1, 2023 |
| Estimated Study Completion Date : | November 1, 2024 |

| Arm | Intervention/treatment |
|---|---|
|
Experimental: KSI-301 - Treatment Group A
Intravitreal injection of KSI-301 (5 mg): three initiating doses, and then every 24 weeks through Week 92
|
Drug: KSI-301
Intravitreal injection |
|
Sham Comparator: Treatment Group B
Sham injection on the same schedule as Treatment Group A
|
Other: Sham injection
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. |
Primary Outcome Measures :
- Proportion of eyes improving ≥2 steps on the ETDRS Diabetic Retinopathy Severity Scale (DRSS) [ Time Frame: Day 1 to Week 48 ]
Secondary Outcome Measures :
- Proportion of eyes developing a Sight-Threatening Complication(s) of DR (DME, PDR, ASNV), as a composite and individually [ Time Frame: Day 1 to Week 48 and Week 96 ]
- Time to development of a Sight-Threatening Complication(s) of DR, as a composite and individually [ Time Frame: Day 1 to Week 96 ]
- Proportion of eyes improving ≥2 or ≥3 steps on the DRSS over time [ Time Frame: Day 1 to Week 48 and Week 96 ]
- Proportion of eyes worsening ≥2 or ≥3 steps on the DRSS over time [ Time Frame: Day 1 to Week 48 and Week 96 ]
- Safety and Tolerability of KSI-301 5 mg compared to sham treatment [ Time Frame: Day 1 to Week 100 ]Incidence of ocular and systemic adverse events

Criteria
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%.
- Other protocol-specified inclusion criteria may apply.
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.
- Other protocol-specified exclusion criteria may apply.
