About this study
Official title: VEGF and HTRA1 DNA Polymorphisms in Neovascular AMD Pathogenesis and Response to Lucentis
The purpose of the study is to investigate whether the efficacy of Lucentis treatment for exudative age-related macular degeneration is associated with VEGF and HTRA1 DNA polymorphisms
Read the detailed description
Age-related macular degeneration (AMD) is a progressive disease that causes irreversible visual impairment and blindness in nearly 50 million people globally. Although geographic atrophy and neovascularization represent the advanced forms of AMD, neovascular AMD is the more aggressive form and accounts for almost 90% of blindness from this disease. It is characterized by choroidal neovascularization (CNV) which is the development of abnormal blood vessels underneath the retina. Randomized clinical trials (MARINA, ANCHOR) have conclusively demonstrated that continued intravitreal therapy with Lucentis (ranibizumab) in patients with subfoveal CNV from AMD leads to stabilization of vision in over 90% of patients and improvement in vision in at least a third of the patients and has led to the approval of Lucentis for the treatment of neovascular AMD (see investigator brochure). This study could provide insight as to the reasons that some patients do not experience vision stabilization with Lucentis, and could possibly help physicians to determine which patients are the best candidates for receiving Lucentis.
This is an open-label study of 100 treatment-naïve (study eye only) AMD patients treated on-label with intravitreally administered Lucentis. Consented, enrolled subjects will receive multiple open-label intravitreal injections of 0.5 mg ranibizumab administered monthly for the first 4 months, and then as needed for a total duration of 12 months. Their blood will be genotyped and sequenced for various SNPs on VEGF and HTRA1.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 14 Aug 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
To Determine the Genotype at VEGF and HTRA1 SNPs of Patients Gaining ≥ 0 Letters of Visual Acuity in Response to Ranibizumab Treatment Over a 4 Month Period. (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01464723, which also lists 1 linked publication.
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 14 Aug 2019.
