About this trial

The purpose of this trial is to study the safety and effectiveness of OTX-TKI (axitinib intravitreal hydrogel) for the treatment of Non-Proliferative Diabetic Retinopathy.

OTX-TKI is an intravitreal hydrogel embedded with axitinib. When the OTX-TKI hydrogel is administered into the vitreous cavity of the eye, the hydrogel begins to slowly break down, which allows the axitinib to be slowly released over time.

This clinical trial is comparing OTX-TKI to a "sham" injection procedure. The sham injection is a mock injection procedure, but nothing will actually be inserted in the eye as there is no needle on the sham injector. Only one eye ("study eye") will be treated with study treatment.

Eligibility criteria

Qualifiers

Male or female who is at least 18 years of age at the time of signing the informed consent form (ICF)

History of or newly diagnosed with type 1 or 2 diabetes mellitus and have moderately severe to severe NPDR (DRSS levels 47 or 53), confirmed by the Central Reading Center (CRC) based on the images obtained at the Screening visit

BCVA Early Treatment Diabetic Retinopathy Study (ETDRS) letter score of ≥ 69 letters (approximate Snellen equivalent of 20/40 or better) in the study eye

Willing and able to comply with clinic visits and study-related procedures

Disqualifiers

Presence of center-involved diabetic macular edema (CI-DME) defined per protocol via optical coherence tomography (SD-OCT) in the study eye, obtained at the Screening visit

Evidence of a rhegmatogenous retinal detachment or visually significant/severe epiretinal membrane, vitreomacular traction syndrome, macular hole, tear of the retinal pigment epithelium in the macula, or other macular pathology in the study eye deemed visually significant by the Investigator

In the study eye, any panretinal photocoagulation (PRP) treatment prior to baseline, or received focal or grid laser photocoagulation within 1000 microns of the central subfield of the macula within 6 months prior to baseline

IVT anti-VEGF treatment in the study eye within 6 months or port delivery system (PDS) with ranibizumab in the study eye at any time prior to baseline (Day 1)

Trial design

Treatments tested in this trial
