NCT04657289

Brief Summary

Study WR42221 is a Phase IIIb, global, multicenter, randomized, visual assessor-masked study designed to assess the efficacy, safety, and pharmacokinetics of the Port Delivery System with ranibizumab (PDS) 100 mg/mL delivered every 36 weeks (Q36W) compared with every 24 weeks (Q24W) in patients with neovascular age-related macular degeneration (nAMD).

Outcome Measures

Primary Outcomes (1)

  • Change from baseline in Best-corrected visual acuity (BCVA) score averaged over Weeks 68 and 72, as assessed using the ETDRS chart starting at a distance of 4 meters

    EDTRS = 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.

    Baseline to Week 72

Secondary Outcomes (19)

  • Change from baseline in BCVA score over time

    Baseline up to Week 72

  • Percentage of participants with BCVA score of 69 letters (approximate 20/40 Snellen equivalent) or better averaged over Weeks 68 and 72

    Baseline to Week 72

  • Percentage of participants with BCVA score of 69 letters (approximate 20/40 Snellen equivalent) or better over time

    Baseline up to Week 72

  • Percentage of participants with BCVA score of 38 letters (approximate 20/200 Snellen equivalent) or worse averaged over Weeks 68 and 72

    Baseline to Week 72

  • Percentage of participants with BCVA score of 38 letters (approximate 20/200 Snellen equivalent) or worse over time

    Baseline up to Week 72

  • +14 more secondary outcomes

Study Arms (2)

Arm A [Q36W] 36-weeks between refill-exchange procedures

EXPERIMENTAL

Drug: RanibizumabDevice: Port Delivery System with Ranibizumab

Arm B [Q24W] 24-weeks between refill-exchange procedures

ACTIVE COMPARATOR

Participants randomized to the Q24W arm will receive PDS implant refill-exchange procedures (ranibizumab 100 mg/mL) on a Q24W fixed interval.

Drug: RanibizumabDevice: Port Delivery System with Ranibizumab

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 50 years at time of signing Informed Consent Form
  • Initial diagnosis of nAMD within 9 months prior to the screening visit
  • Previous treatment with at least three anti- vascular endothelial growth factor (VEGF) intravitreal injections for nAMD per standard of care within 6 months prior to the screening visit
  • Demonstrated response to prior anti-VEGF intravitreal treatment since diagnosis
  • Availability of historical visual acuity data prior to the first anti-VEGF treatment for nAMD until the time of study enrollment
  • BCVA of 34 letters (approximate 20/200 Snellen equivalent) or better

You may not qualify if:

  • History of vitrectomy surgery, submacular surgery, or other surgical intervention for AMD in study eye
  • Prior treatment with Visudyne®, external-beam radiation therapy, or transpupillary thermotherapy in study eye
  • Previous treatment with corticosteroid intravitreal injection, intraocular device implantation, previous laser (any type) used for AMD treatment in study eye
  • Treatment with anti-VEGF agents other than ranibizumab within 1 month prior to the enrollment visit in study eye
  • Concurrent conjunctival, Tenon's capsule, and/or scleral condition in the supero-temporal quadrant of the eye that may affect the implantation, subsequent tissue coverage, and refill-exchange procedure of the PDS implant
  • Prior treatment with brolucizumab (at any time prior to the screening visit) in either eye
  • Prior participation in a clinical trial involving any anti-VEGF drugs, within 9 months prior to the enrollment visit in either eye
  • Subretinal hemorrhage that involves the center of the fovea, if the hemorrhage is \>0.5 disc area at screening in study eye
  • Subfoveal fibrosis or subfoveal atrophy in study eye
  • Choroidal neovascularization (CNV) due to other causes, such as ocular histoplasmosis, trauma, central serous chorio-retinopathy, or pathologic myopia in either eye
  • Retinal pigment epithelial tear in study eye
  • Any concurrent intraocular condition that would either require surgical intervention during the study to prevent or treat visual loss that might result from that condition or affect interpretation of study results in study eye
  • Active intraocular inflammation in study eye
  • History of vitreous hemorrhage in study eye
  • History of rhegmatogenous retinal detachment in study eye
  • +21 more criteria
