About this study
Official title: Comparison of Intravitreal Dexamethasone With Intravitreal Ranibizumab Versus Intravitreal Ranibizumab Monotherapy in Recurrent or Persistent Choroidal Neovascularization Secondary to Age-related Macular Degeneration A Prospective, Randomized, Clinical Study
Age-related macular degeneration (AMD) is by far the most common disorder in the group of irreversible causes of visual disability. AMD leads to dysfunction and loss of photoreceptors in the central retina. Neovascular AMD (nAMD) affects visual function early in the disease process and severely compromises the highly developed functions of the macula, such as perception of details, central fixation, color vision, and reading ability. AMD-related visual impairment is associated with a loss of autonomy and quality of life. Current therapeutic approaches target vascular endothelial growth factor (VEGF), which has been identified as a main cytokine in the pathogenesis of nAMD. Ranibizumab, the fab-fragment of an antibody targeting VEGF is approved for the treatment of nAMD applied intravitreally in monthly intervals until the disease activity is stopped. However, a significant proportion of patients with nAMD suffer from persistent or recurring disease with the need of continuous anti-VEGF therapy over months and years, often leading to irreversible changes in the photoreceptor layer and the pigment epithelium.
Recent studies regarding the treatment of nAMD utilized different forms of therapies, combining photodynamic therapy with verteporfin (PDT) and ranibizumab, as well as therapeutic regimen containing steroids. Even though these studies did not provide evidence that combination therapies are superior to ranibizumab monotherapy, studies were only conducted with patients with previously untreated nAMD. Therefore, currently there is no alternative therapeutic approach for patients with recurrent or persistent form of nAMD after multiple treatments with ranibizumab monotherapy.

The purpose of this study is to assess the treatment effect of reduced fluence PDT and intravitreal ranibizumab versus intravitreal dexamethasone and ranibizumab versus intravitreal ranibizumab monotherapy in patients with persistent or recurrent choroidal neovascularization (CNV) due to AMD.
The investigators hypothesis is that these findings will offer new insights in the management of persistent or recurrent CNV secondary to AMD.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intravitreal dexamethasone and intravitreal ranibizumabDrug
Patients will receive intravitreal dexamethasone using a special drug delivery system and same day intravitreal ranibizumab.
Study medications are initially given at the baseline visit. At each subsequent monthly follow-up visit, ranibizumab is administered if further visual decrease or persistence of sub-/intraretinal fluid is detected in the examination. At month 3, 6, 9 and 12 further treatments with intravitreal dexamethasone in combination with intravitreal ranibizumab are given if leakage is detected in fluorescein or indocyanine green (FLA or ICG) angiography, in case of further vision decrease or persistence of sub-/intraretinal fluid in OCT.
Intravitreal ranibizumabDrug
Patients will receive intravitreal ranibizumab monotherapy (cohort 3). Study medications are initially given at the baseline visit. At each subsequent monthly follow-up visit, ranibizumab is administered if further visual deterioration or persistence of sub-/intraretinal fluid is detected in the examination

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Intravitreal dexamethasone and intravitreal ranibizumab and Intravitreal ranibizumab in people with Age-Related Macular Degeneration and Neovascularization, Choroidal, run by Medical University of Vienna at 1 site in Austria.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 May 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
• Central visual function. (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 May 2017.
