About this study

Official title: AflibercepT for Subjects Who Are Incomplete Responders to mUltiple Intravitreal Injections of Ranibizumab, Anti-VegF (The TURF Study)

50 Patients with recalcitrant exudative age-related macular degeneration with a history of retinal or subretinal fluid after multiple intravitreal injections with ranibizumab 0.5mg and subsequently treated with ranibizumab 2.0mg, who are incomplete responders to 2.0mg of ranibizumab.

Read the detailed description

The rationale for the TURF trial is based on the greater binding affinity of VEGF Trap-eye, which theoretically may prove to be more effective for recalcitrant wet AMD and therefore may demonstrate a positive impact on visual acuity and the foveal anatomy of subjects who have a history of a less than optimal anatomical and visual response to multiple intravitreal injections of 2.0mg (super-dose) ranibizumab. Based on the anatomical data from the VIEW1 and VIEW2 trials, approximately 70% of VEGF-Trap eye patients had no evidence of fluid on OCT compared to approximately 55% of ranibizumab patients. One potential interpretation of this clinical data is that the increased binding affinity and longer half-life of VEGF-Trap eye result in the resolution of more fluid for a longer duration of effect.

Patients to be enrolled in this study have a history of requiring monthly dosing of ranibizumab 2.0mg to achieve maximum resolution of fluid on OCT and increased visual acuity. These patients initially showed minimal fluid resolution visual acuity gains while treated with Lucentis (0.5mg ranibizumab) and were subsequently treated with 2.0mg monthly. It is expected that treating these same patients with 2.0mg EYLEA™ (aflibercept injection for eye) will maintain the fluid resolution on OCT and visual acuity gains previously requiring a super-dose of ranibizumab.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Number of Patients With no Fluid on OCT

    Measured: 6 months

Secondary outcomes (6)

  1. Mean Change in OCT Central Foveal Thickness

    Measured: 6 Months

  2. Average Time to Resolution of Intraretinal Cysts and Sub Retinal Fluid on OCT

    Measured: 6 months

  3. The Percentage of Patients Who Lose > 15 Letters Visual Acuity

    Measured: 6 Months

  4. Mean Change in Visual Acuity (BCVA)

    Change in Early Treatment of Diabetic Retinopathy Study Best Corrected Visual Acuity (ETDRS-BCVA) from baseline to month 6. BCVA is measured using an eye chart and is reported as the number of letters read correctly using the ETDRS Scale (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved.

    Measured: 6 Months

  5. Quantitative Change in Area (μ) From Baseline in Choroidal Neovascular Lesion Characteristics/Size as Measured by FA/Fundus Photos

    Measured: 6 Months

  6. Mean Number of 0.2 mg Aflibercept Injections Administered

    Measured: at 6 months

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 19 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 2 Jan 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 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 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 2 Jan 2017). 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?

The Number of Patients With no Fluid on OCT (time frame: 6 months). 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 NCT01543568, which also lists 16 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 2 Jan 2017.
