Study Endpoints

Primary Endpoints

Proportion of participants with ≥ 15 letter improvement from baseline in best-corrected visual acuity (BCVA) at Week 16
Week 16
Change From Baseline in Best-Corrected Visual Acuity (BCVA) Averaged Over Week 44 and Week 48, in Treatment-naïve Participants
Baseline, Weeks 44 and 48

The BCVA, at a starting test distance of 4 meters (m), was measured for both eyes, prior to dilating eyes by using the set of three Precision visionTM or Lighthouse distance acuity charts (modified early treatment diabetic retinopathy study \[ETDRS\] charts 1, 2 and R) by trained and certified personnel at the study sites and at each study visit. The BCVA letter score ranges from 0 to 100 (best score attainable), and a gain in BCVA letter score from baseline indicates an improvement in visual acuity. This analysis used a Mixed Model for Repeated Measurements (MMRM) model. Adjusted mean has been reported.

Change From Baseline in Best Corrected Visual Acuity (BCVA) Averaged Over Week 44 and Week 48 in Treatment-naïve Participants
Baseline, Week 44 and Week 48

BCVA was measured via Early Treatment Diabetic Retinopathy Study (ETDRS) chart at a starting distance of 4 meters using a set of three Precision vision\^TM or Lighthouse distance acuity charts (modified ETDRS Charts 1, 2, and R) prior to dilating eyes by a trained and certified visual acuity (VA) examiner. The BCVA letter score ranges from 0 to 100 letters. Higher scores and gain in BCVA from baseline indicate improvement in VA. This analysis used a Mixed Model for Repeated Measurements (MMRM) model.

A sham procedure will be administered during study visits at which no study drug is administered to maintain masking between treatment arms.
Arm C: 1.0 mg Vamikibart Q4WEXPERIMENTALParticipants will receive vamikibart 1.0 mg, by IVT injection, on Day 1 and every 4th week (Q4W), up to Week 44 for a total of 12 injections.
Arm D: 0.5 mg Ranibizumab Q4WACTIVE_COMPARATORParticipants will receive ranibizumab 0.5 mg, by IVT injection, on Day 1 and Q4W, up to Week 44 for a total of 12 injections.
Arm A: Vamikibart + RanibizumabEXPERIMENTALParticipants will receive vamikibart, 1 milligram (mg) administered as intravitreal (IVT) injection in combination with ranibizumab, 0.5 mg IVT, on Day 1 and every fourth week (Q4W) up to Week 44, for a total of 12 injections, followed by an observational period up to Week 72.
Arm B: RanibizumabACTIVE_COMPARATORParticipants will receive ranibizumab, 0.5 mg IVT, from Day 1 and Q4W in combination with sham up to Week 44, for a total of 12 injections, followed by an observational period up to Week 72.
Part 1: RO7200220 MonotherapyEXPERIMENTALParticipants with DME received multiple ascending doses of RO7200220 (two doses at the assigned dose level), as intravitreal (IVT) injection, every 6 weeks (Q6W) in multiple cohorts.
Part 2: Expansion of RO7200220 MonotherapyEXPERIMENTALParticipants with DME who were anti-VEGF and corticosteroid IVT treatment-naive received three doses of RO7200220 monotherapy, as IVT injection, every 4 weeks (Q4W) in Part 2 cohorts.
Part 3: RO7200220 in Combination with RanibizumabEXPERIMENTALParticipants with DME received RO7200220 as IVT injection followed by ranibizumab, 0.5 milligrams (mg) as IVT injection in Part 3.
Part 4: RO7200220 MonotherapyEXPERIMENTALParticipants with UME received multiple doses of RO7200220 (three doses at the assigned dose level), as IVT injection, Q4W in multiple cohorts.

Frequently asked questions about RO7200220

What is RO7200220 used for?

RO7200220 is an investigational small molecule being developed for diabetic macular edema, a condition that causes vision loss due to fluid buildup in the macula. It is also being studied for uveitic macular edema. The drug is in Phase 1 clinical development and is not yet approved by the FDA.

Who makes RO7200220?

RO7200220 is being developed by Roche Holding AG, which trades under the ticker RHHBY. The company is conducting clinical trials of the drug in the United States for diabetic macular edema and uveitic macular edema.
