ETDRS-DRSS classifies diabetic retinopathy (DR) into 12 severity steps ranging from absence of retinopathy to advanced proliferative diabetic retinopathy (PDR). DRSS grades= 10 (DR absent) - 85 (very advanced PDR), DRSS 90 = ungradable. All DRSS values are converted into a 12-level scale, from 1 (DR absent) to 12 (very advanced PDR), allowing derivation of ≥2-step change from baseline for post-baseline assessment. A lower score represents less advanced diabetic retinopathy. The Cochran-Mantel Haenszel (CMH) method was used for analysis and weighted percentage of participants are estimated and reported in this outcome measure. Participants receiving supplemental treatments, prohibited therapy, or panretinal photocoagulation (PRP) were considered non-responders. Missing values not preceded by these intercurrent events were imputed using the last observation carried forward method. SD OCT= spectral-domain optical coherence tomography.
BCVA = Best-Corrected Visual Acuity ETDRS = Early Treatment Diabetic Retinopathy Study A vision score of 20/20 vision is considered normal. A score of 20/200 is considered being legally blind.
| Arm | Type | Description |
|---|---|---|
| PDS Arm | EXPERIMENTAL | Participants randomized to the PDS arm will receive two intravitreal ranibizumab injections and will then have the PDS implant (pre-filled with ranibizumab) surgically inserted. PDS implant refill-exchange procedures will be performed on a fixed interval every 36-weeks (Q36W) thereafter |
| Comparator Arm | OTHER | Participants randomized to the comparator arm will undergo study visits every 4 weeks (Q4W) for comprehensive clinical monitoring until they receive the PDS implant (pre-filled with ranibizumab). PDS implant refill-exchange procedures will be performed on a fixed interval Q36W thereafter. Participants will be eligible to receive intravitreal ranibizumab 0.5 mg injections if treatment eligibility criteria are met. |
| Intravitreal Arm | ACTIVE_COMPARATOR | Participants randomized to the intravitreal arm will receive IVT ranibizumab injection Q4W until they receive the PDS implant (pre-filled with ranibizumab). PDS implant refill-exchange procedures will be performed on a fixed interval Q24W thereafter. |
| Substudy: Cohort 1 | EXPERIMENTAL | Participants will undergo re-implantation with the updated PDS implant (pre-filled with ranibizumab 100 milligrams per milliliter \[mg/mL\]) on Day 1 (or enrollment visit) and then will have two refill-exchanges (ranibizumab 100 mg/mL) Q24W up to 48 weeks. |
| Substudy: Cohort 2a | EXPERIMENTAL | Participants who received an updated PDS implant, have \< 24 weeks post-re-implantation follow-up and no scheduled refill-exchange visit in the main study, will undergo two refill-exchange procedures (ranibizumab 100 mg/mL) Q24W, post main study re-implantation visit. |
| Substudy: Cohort 2b | EXPERIMENTAL | Participants who received an updated PDS implant, have \< 48 weeks post-re-implantation follow-up and one refill exchange visit in the main study, regardless of whether the refill exchange was administered or the visit was missed, will undergo one refill-exchange procedure (ranibizumab 100 mg/mL) Q24W, post main study re-implantation visit. |
| PDS Implant Cohort 1 (US only) | EXPERIMENTAL | Participants with PDS implant from Study GX28228 treated with refill-exchanges of 100 mg/mL ranibizumab Q24W. Participants will switch to an every 12 weeks (Q12W) visit schedule from Week 168 to Week 240. Eligible participants from Study GX28228 will be enrolled upon completion of their final visit. |
| PDS Implant Cohort 2 (US only) | EXPERIMENTAL | Participants with PDS implant from Study GR40548 treated with refill-exchanges of 100 mg/mL ranibizumab Q24W. Participants will switch to an every 12 weeks (Q12W) visit schedule from Week 144 to Week 240. Eligible participants from Study GR40548 will be enrolled upon completion of their final visit. |
| PDS Implant Cohort 3 (US only) | EXPERIMENTAL | Participants in the intravitreal ranibizumab arm of Study GX28228 who will receive the PDS implant upon study entry and refill-exchanges of 100 mg/mL ranibizumab Q24W. Participants will switch to an every 12 weeks (Q12W) visit schedule from Week 168 to Week 240. Eligible participants from Study GX28228 will be enrolled upon completion of their final visit. |
| PDS Implant Cohort 4 (US only) | EXPERIMENTAL | Participants in the intravitreal ranibizumab arm of Study GR40548 who will receive the PDS implant upon study entry and refill-exchanges of 100 mg/mL ranibizumab Q24W. Participants will switch to an every 12 weeks (Q12W) visit schedule from Week 144 to Week 240. Eligible participants from Study GR40548 will be enrolled upon completion of their final visit. |
| PDS Implant Cohort 5 (ex-US only) | EXPERIMENTAL | Participants from Study WR42221 who completed Week 24 but were not eligible to be randomized within WR42221 and who will be treated with refill-exchanges of ranibizumab 100 mg/mL Q24W. Participants will be in the study for a minimum of 144 weeks and may continue after Week 144 until the PDS has received Health Authority approval (or non-approval) in their respective country and/or until the decision to close the study has been made by the sponsor. |
| PDS Implant Cohort 6 (ex-US only) | EXPERIMENTAL | Participants from Study WR42221 randomized to the Q24W arm, who will continue to be treated with refill-exchanges of ranibizumab 100 mg/mL Q24W. Participants will be in the study for a minimum of 144 weeks and may continue after Week 144 until the PDS has received Health Authority approval (or non-approval) in their respective country and/or until the decision to close the study has been made by the sponsor. |
