NCT04108156

Brief 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 Arms (5)

PDS Arm

EXPERIMENTAL

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.

Drug: PDS Implant Pre-Filled with 100 mg/mL RanibizumabDrug: Ranibizumab refill exchange

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.

Drug: Intravitreal Ranibizumab 0.5 mg InjectionDrug: Ranibizumab refill exchange

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.

Drug: PDS Implant Pre-Filled with 100 mg/mL RanibizumabDrug: Ranibizumab refill exchange

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.

Drug: Ranibizumab refill exchange

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.

Drug: Ranibizumab refill exchange

  • Macular thickening secondary to DME involving the center of the fovea with CST ≥325 micrometer (µm) on SD-OCT at screening
  • BCVA score of 78 to 25 letters (20/32 to 20/320 approximate Snellen equivalent)

You may not qualify if:

  • High-risk PDR
  • Active intraocular inflammation (grade trace or above)
  • Suspected or active ocular or periocular infection of either eye
  • Uncontrolled ocular hypertension or glaucoma and any such condition the investigator determines may require a glaucoma-filtering surgery during a patient's participation in the study

  • Atrial fibrillation diagnosis or worsening within 6 months prior to randomization
  • Uncontrolled blood pressure
  • Substudy:
  • Having experienced a septum dislodgement in the original implant while in the main study or after exiting the main study
  • Sufficiently clear ocular media and adequate pupillary dilation to allow for analysis and grading by central reading center
  • Recent history (in the last 3 months prior to enrollment) of other disease, other non-diabetic metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a condition that contraindicates the use of ranibizumab or surgical placement of the PDS implant; that might affect interpretation of the results of the study; or that renders the participant at high risk for treatment complications
  • Active cancer within the last 12 months, except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, or prostate cancer
  • Current systemic treatment for a confirmed active systemic infection
  • Participation in an investigational trial that involves treatment with any drug or device (with the exception of vitamins and minerals or enrollment in Study GR40550) within 6 months prior to enrollment
  • Use of antimitotic or antimetabolite therapy within 30 days
