About this study
Official title: A Phase 1, Open-Label, Multi-Center, Dose-Escalating, Safety and Tolerability Study of a Single Intravitreal Injection of AAV2-sFLT01 in Patients With Neovascular Age-Related Macular Degeneration
This Phase 1 clinical research study will examine the safety and tolerability of an experimental gene transfer agent, AAV2-sFLT01, in patients with Neovascular Age-Related Macular Degeneration (AMD).
Read the detailed description
A new treatment for neovascular age-related macular degeneration (AMD) is being investigated. Neovascular AMD is sometimes referred to as the "wet" form of AMD. The purpose of this Phase 1 clinical research study is to examine the safety and ability of an experimental study drug to treat a complication of the disease which leads to vision loss. The name of the study drug is "AAV2-sFLT01." This experimental study drug uses a virus to transfer a gene (genetic code) into cells within the eye. The gene codes for a protein that is intended to diminish the growth of abnormal blood vessels under the retina. The duration of the gene's effect is currently unknown, but might last for years.
This clinical research study will look at the safety of a single administration of AAV2-sFLT01 injected directly into the eye. There are 2 parts to this study, but patients will take part in only one of them. In the first part of the study, 4 different doses of the study drug will be studied in 4 separate groups of patients. Patients in the first part of the study will not be randomized. In the second part of the study, the highest dose that was safe and well tolerated will be studied in 10 more patients. Patients in this part of the study may have a ranibizumab (Lucentis®) injection 26 weeks after their AAV2-sFLT01 injection to verify their responsiveness to anti-VEGF therapy, if they have not demonstrated a response to AAV2-sFLT01. The initial two parts of this protocol are expected to be completed in July, 2013.
All patients injected with AAV2-sFLT01 will be asked to participate in an Extended Follow-Up (EFU) program for up to an additional 4 years. Participation is voluntary but strongly encouraged as it allows for the long term collection of safety information as well as information about the potential long term effects of the study drug. Study visits will take place at the site every 6 months.
Up to thirty-four (34) patients at multiple centers will take part in this study in the United States.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing AAV2-sFLT01 in people with Macular Degeneration and Age-Related Maculopathies, run by Genzyme, a Sanofi Company at 4 sites 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 8 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 22 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites 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 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.
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?
Maximum tolerated dose of a single uniocular intravitreal injection of AAV2-sFLT01 (time frame: Time of treatment through Week 52 (referred to as the "core" study)). The study lists 3 primary outcomes in all. 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 NCT01024998, which also lists 2 linked publications.
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 22 Aug 2018; AzTrials last refreshed its copy on 8 Nov 2026.
