Registered outcomes6

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryMean Change in BCVADay 1 to Week 64
Mean change in best-corrected visual acuity (BCVA) from baseline to the average of Weeks 60 and 64 (using Early Treatment Diabetic Retinopathy Study (ETDRS) Letters). Best Corrected Visual Acuity (BCVA) was measured on the Early Treatment Diabetic Retinopathy Study (ETDRS) chart at a starting distance of 4 meters. The BCVA letter score ranges from 0 to 100 (best score), and a gain in BCVA letter score from baseline indicates an improvement in visual acuity.
SecondaryPercentage of Patients With a ≥ 2-step Worsening on the ETDRS DRSS in Studies KS301P104 and KS301P105 CombinedDay 1 to Week 52
Percentage of patients with a ≥ 2-step worsening on the Early Treatment Diabetic Retinopathy Study (ETDRS) Diabetic Retinopathy Severity Scale (DRSS) from baseline at Week 52 using last observation carried forward (LOCF) in Studies KS301P104 and KS301P105 combined. The Diabetic Retinopathy Disease Severity Scale (DRSS) may be used to describe overall retinopathy severity as well as the change in severity over time. Severity range from level 10 (DR absent) to level 85 (advanced proliferative DR: posterior fundus obscured, or center of macula detached).
SecondaryPercentage of Patients With a ≥ 2-step Worsening on the ETDRS DRSS in Study KS301P104Day 1 to Week 52
Percentage of patients with a ≥ 2-step worsening on the Early Treatment Diabetic Retinopathy Study (ETDRS) Diabetic Retinopathy Severity Scale (DRSS) from baseline at Week 52 using last observation carried forward (LOCF) in Study KS301P104. The Diabetic Retinopathy Disease Severity Scale (DRSS) may be used to describe overall retinopathy severity as well as the change in severity over time. Severity range from level 10 (DR absent) to level 85 (advanced proliferative DR: posterior fundus obscured, or center of macula detached).
SecondaryPercentage of Patients in the KSI-301 Arm on a Q8W, Q12W, Q16W, Q20W, or Q24W Treatment IntervalWeek 56
Percentage of patients in the KSI-301 arm on a Q8W, Q12W, Q16W, Q20W, or Q24W treatment interval at the primary endpoint. Analyses include KSI-301 patients who completed a treatment interval from Week 56 onwards.
SecondaryMean Number of Intravitreal InjectionsDay 1 to Week 60Mean number of intravitreal injections from Day 1 to Week 60
SecondaryMean Change in OCT CSTDay 1 to Week 64Mean change in Optical Coherence Tomography (OCT) central subfield retinal thickness (CST) from baseline to the average of Weeks 60 and 64
