A Phase III, Multicenter, Randomized, Visual Assessor-Masked, Active-comparator Study of the Efficacy, Safety, and Pharmacokinetics of the Port Delivery System With Ranibizumab in Patients With Diabetic Macular Edema (Pagoda)
In Brief
A Phase 3 clinical trial evaluating PDS Implant Pre-Filled with 100 mg/mL Ranibizumab, Intravitreal Ranibizumab 0.5 mg Injection, and 1 other intervention for Diabetic Macular Edema. Active but no longer recruiting, targeting 634 participants across 88 sites.
Detailed Summary
This study will evaluate the efficacy, safety, and Pharmacokinetics (PK) of the PDS with ranibizumab in participants with DME when treated every 24 weeks (Q24W) compared with intravitreal (IVT) ranibizumab 0.5 milligrams (mg) every 4 weeks (Q4W). The substudy will evaluate safety of re-implanting the updated PDS with ranibizumab and the refill-exchange procedures following re-implantation in participants with DME who were previously enrolled in the main study, GR40550. Up to 100 participants from the main study will be enrolled and followed for a maximum of 72 weeks post-re-implantation in the substudy.
Study Details
Timeline
Arms & Interventions
Participants randomized to the PDS arm will receive IVT ranibizumab injection Q4W (loading phase) 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 Q24W thereafter.
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.
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.
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.
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.
