Abstract
Purpose :
To evaluate efficacy and safety of IAI for treatment of patients with moderately severe to severe NPDR.
Methods :
PANORAMA is a double-masked, randomized, phase 3 clinical trial. Patients ≥18 years of age with type 1 or 2 diabetes mellitus were eligible for enrollment if they had moderately severe to severe NPDR (Diabetic Retinopathy Severity Scale [DRSS] levels 47 to 53) without diabetic macular edema (DME) and who could safely defer panretinal photocoagulation for at least 6 months. Baseline best-corrected visual acuity (BCVA) ETDRS letter score had to be ≥69 letters (approximate Snellen equivalent of 20/40 or better) in the study eye. Patients were randomized in a 1:1:1 ratio to receive IAI 2 mg q8 weeks after five initial monthly doses (2q8), IAI 2 mg q16 weeks after three initial monthly doses and one 8-week interval (2q16), or sham injections through week 48. The primary outcome measure is the proportion of patients who had ≥2-step improvement in the DRSS score from baseline at weeks 24 and 52.
Results :
Enrollment in the PANORAMA study is complete with 402 patients participating from 5 countries (United States, Japan, Germany, Hungary, and United Kingdom). Mean (SD) age at baseline is 55.7 (10.5) years. Overall, 44.0% of patients are women, and 56.0% are men. Primary results through week 24 will be presented.
Conclusions :
Results from this first phase 3 study using an anti-VEGF agent for the treatment of moderately severe to severe NPDR, in patients without DME, will provide insight into the role of IAI therapy in the management of this disease.
