Trial summary

Angioid streaks are rare lesions associated to retinal pigment epithelium degenerations. They can be caused by general diseases as pseudoxanthoma elasticum, Paget's disease or drepanocytosis. Choroidal neovascularization (CNV) represents the most frequent complication for those patients. Read more about this study

About this study

Official title: Phase II Study Evaluating the Efficacy of Aflibercept for the Treatment of Choroidal Neovascularization in Angioid Streaks in Young Patients.

Angioid streaks are rare lesions associated to retinal pigment epithelium degenerations.

They can be caused by general diseases as pseudoxanthoma elasticum, Paget's disease or drepanocytosis. Choroidal neovascularization (CNV) represents the most frequent complication for those patients. It leads to a rapid and important loss of visual acuity. CNV in angioid streaks represent the fourth leading cause of CNV in young patients.

Read more

CNV in angioid streaks is treated at the moment with off-label anti-VEGF (Vascular Endothelial Growth Factor) therapy and could also benefit from aflibercept (EYLEA), a new anti-VEGF currently indicated in AMD. Case reports suggest that such patients would not need as many injections as in AMD.

ASTRID is an open-label, single arm, prospective, multicenter, phase II study. The main objective is to demonstrate the effectiveness in clinical terms after 52 weeks of treatment with aflibercept on the visual acuity of patients affected by CNV in angioid streaks. A specific dosage regimen is designed to achieve maximum efficiency. The patients are followed on a monthly basis until 52 weeks. Six injections are mandatory, the other ones are injected only in case of active CNV.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AfliberceptDrug

    The patients are followed on a monthly basis until 52 weeks. Intravitreal injections of aflibercept at a dosage of 2 mg are initiated at inclusion (mandatory injection) followed by mandatory injections at week 4, week 8, week 20, week 32 and week 44. During the other visits, an injection can be performed in case of CNV activity (PRN regimen).Therefore, each patient receives between 6 and 13 injections in the whole study.

What is being measured

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

  1. Mean change in best corrected visual acuity (BCVA) from baseline to 52 weeks in patients with choroidal neovascularization in angioid streaks treated with Aflibercept

    Change in BCVA number of letters gained or lost between baseline and 52 weeks. BCVA is measured on the scale Early Treatment Diabetic Retinopathy Study (ETDRS) at an initial distance of 4 meters.

    Measured: 52 weeks

Secondary outcomes (9)
  1. Mean change in BCVA from baseline to 24 weeks

    Mean change in BCVA expressed as number of letters gained or lost measured with ETDRS scale from baseline to week 24

    Measured: 24 weeks

  2. Percentage of patients who lost fewer than 15 letters of BCVA from baseline to 24 weeks.

    percentage of the patients who lost fewer than 15 letters of BCVA measured with ETDRS scale from baseline to week 24.

    Measured: 24 weeks

  3. Percentage of patients who lost fewer than 15 letters of BCVA from baseline to 52 weeks

    Percentage of the patients who lost fewer than 15 letters of BCVA measured with ETDRS scale from baseline to week 52.

    Measured: 52 weeks

  4. number of injections per patient for 52 weeks

    Measured: 52 weeks

  5. Average change in central retinal thickness (CRT) between baseline and 24 weeks

    Average change in central retinal thickness (CRT) in micrometers measured with Spectral domain Optical Coherence Tomography (SD-OCT) from baseline to week 24

    Measured: 24 weeks

  6. Average change in central retinal thickness (CRT) between baseline and 52 weeks

    Average change in central retinal thickness (CRT) in micrometers measured with Spectral domain Optical Coherence Tomography (SD-OCT) from baseline to week 52

    Measured: 52 weeks

  7. Mean change in neovascular lesion size between baseline and 52 weeks.

    change in neovascular lesion size measured with fluorescein and/or indocyanine green angiography from baseline to week 52

    Measured: 52 weeks

  8. Mean change in neovascular lesion morphology between baseline and 52 weeks.

    Mean change in neovascular lesion morphology measured with fluorescein and/or indocyanine green angiography from baseline to week 52

    Measured: 52 weeks

  9. Side-effects observed during the study

    Measured: 52 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Aflibercept in people with Choroidal Neovascularization in Angioid Streaks, run by Hospices Civils de Lyon.

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 28 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: withdrawn, as of the sponsor's last update on 6 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

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 was withdrawn before enrolling participants, so there are no results.

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?

Mean change in best corrected visual acuity (BCVA) from baseline to 52 weeks in patients with choroidal neovascularization in angioid streaks treated with Aflibercept (time frame: 52 weeks). 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 6 Jan 2017.
