About this study
Official title: A Prospective Study Comparing Ranibizumab Plus Dexamethasone Combination Therapy Versus Ranibizumab Monotherapy for Wet Age-related Macular Degeneration
The primary objective of this proposed research study is to evaluate the safety of intravitreal ranibizumab in combination with intravitreal dexamethasone in comparison to intravitreal ranibizumab alone in the treatment of wet ARMD. The addition of the broad spectrum anti-inflammatory activity of dexamethasone may augment the anti-VEGF activity of ranibizumab by amelioration of inflammation existing in the microenvironment of the choroidal neovascularization. While the anti-VEGF agents have proven to be very efficacious in the treatment of exudative ARMD, their narrow target and window of activity may limit their overall durability of action.
Read the detailed description
A prospective, single masked comparative trial using either combination therapy (group 1): same day combination therapy with 0.05cc intravitreal dexamethasone injection (10mg/ml vial) and a single 0.5 mg intravitreal ranibizumab injection for four consecutive months will be compared to monotherapy (group 2): one intravitreal injection of 0.5 mg ranibizumab also given for four consecutive months. These treatments will then be followed by PRN treatment based on clinical exam, angiographic studies, and OCT evidence of residual subretinal fluid, CME, subretinal hemorrhage, or pigment epithelial detachment. Fluorescein angiography and fundus photography will be performed at baseline and at the 1, 3, 6, and 12 month follow-up visits. Only OCT testing will be performed at all follow-up visits. Both groups will be re-evaluated for safety at 12 and 24 months.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing ranibizumab and dexamethasone and Ranibizumab in people with Exudative Age-Related Macular Degeneration, run by Subhransu K. Ray, M.D., Ph.D. at 1 site in United States.
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 16 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 19 Dec 2012. 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 United States. 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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Incidence and severity of ocular adverse events and visual acuity (time frame: 6 months and 12 months). 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 19 Dec 2012.
