Study summary

The purpose of the study is to detect persisting or early new activity of choroidal neovascularization (CNV) due to age related macular degeneration (AMD) during the first 12 months following the first ranibizumab dose at baseline as assessed by weekly high resolution optical coherence tomography (OCT). Detection of persisting or new signs of CNV activity at OCT triggers further ranibizumab treatments considering that any ranibizumab injections can maximally be applied as often as 2-weekly.

Read the detailed description

This is a prospective, 1-arm, monocenter study designed to evaluate the time course of early re-activation of CNV assessed by High Resolution OCT. An OCT-guided high frequency (up to 2-weekly) intravitreal ranibizumab treatment in CNV due to AMD may prevent further growth and early re-growth of CNV as evaluated by OCT at a weekly basis.

Consenting, enrolled patients will receive one 0.5 mg ranibizumab intravitreal injection at baseline (month 0). Afterwards all patients will undergo a weekly OCT assessment. Further treatments, which can maximally be applied as often as 2-weekly, are triggered by persisting or new signs of CNV activity at OCT as defined by intraretinal cysts or subretinal fluid. For this study, a month is defined as 28 days, a 2-week period as 14 days. During the 12-month study period, a maximum of 24 ranibizumab injections may be administered.

An interim analysis will not be performed. The study will be conducted in compliance with the protocol, GCP and the applicable regulatory requirement(s).

Inclusion criteria

  • Male or female patients ≥ 50 years of age.
  • Patients with active primary subfoveal CNV secondary to AMD, including those with predominantly classic, minimally classic or occult lesions with no classic component.
  • Evidence that CNV extends under the geometric center of the foveal avascular zone.
  • Total CNV area encompassed within the lesion must be ≥ 50% of total lesion area.
  • The total lesion area ≤ 12 disc areas for minimally classic or occult with no classic component and ≤ 9 disc areas (5400µm) in greatest linear dimension with predominantly classic lesions.
  • Patients who have a BCVA of 20/32 to 20/320 (letter score of 78 to 25 letters) in the study eye using ETDRS charts.
  • Willing and able to give written according to legal requirements, and who have signed the consent form prior to initiation of any study procedure.
  • Willing and able to comply with study procedures.

Exclusion criteria

Exclusion Criteria:

  • Subretinal hemorrhage in the study eye that involves the center of the fovea, if the size of the hemorrhage is either ≥ 50% of the total lesion area or ≥ 1 disc area in size.
  • Structural damage to the center of the macula (beside CNV) in the study eye.
  • Presence of a retinal pigment epithelial tear involving the macula in the study eye.
  • Patients with angioid streaks or precursors of CNV in either eye due to other causes.
  • Concurrent disease in the study eye that could compromise visual acuity or require medical or surgical intervention during the 12-month study period.
  • Vitreous hemorrhage, history of rhegmatogenous retinal detachment or macular hole.
  • Active intraocular inflammation (grade trace or above) in the study eye.
  • Any active infection involving ocular adnexa.
  • History of uncontrolled glaucoma in the study eye.
  • Aphakia with absence of the posterior capsule in the study eye.
  • Any prior treatment in the study eye with verteporfin, subfoveal focal laser photo-coagulation, vitrectomy, transpupillary thermotherapy, intravitreally applied drugs.
  • History of submacular surgery or other surgical intervention for AMD in the study eye.
  • Extracapsular extraction of cataract within 3 months preceding Baseline.
  • Previous violation of posterior capsule in the study eye (unless YAG capsulotomy).
  • History of Stroke.
  • Pregnant or nursing (lactating) women.
  • History of or allergy to fluorescein.
  • Inability to obtain OCT/photographs/fluorescein angiograms of sufficient quality.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 8, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
