About this study

Official title: Ranibizumab in Choroidal Neovascularization (CNV) Due to Pseudoxanthoma Elasticum (PXE, Groenblad-Strandberg-Syndrome)

The purpose of the study is to investigate the efficacy of a new drug called ranibizumab in the treatment of choroidal neovascularization in underlying angioid streaks due to Pseudoxanthoma elasticum. 10 patients will receive monthly injections of the drug in one eye over a period of one year.

Read the detailed description

Pseudoxanthoma elasticum (PXE) is a rare hereditary systemic disease affecting mainly the skin, eyes and the cardiovascular system. Commonly, complicating choroidal neovascularization (CNV) of the central retina lead to a severely decreased visual acuity in the course of the disease. Onset of the symptoms varies with the extend of the PXE-associated findings.

In the past there has been no effective treatment for the disease's ocular complications. Recent studies in a limited number of patients with CNV treated with intravitreal injections of bevacizumab, an antagonist targeting vascular endothelial growth factor (VEGF), have shown a preservation of function and regression of CNV. An increase of visual acuity was reported in a subset of patients. Bevacizumab is a humanized antibody of which ranibizumab is a fragment.

This trial is initiated in order to investigate the effect of ranibizumab on functional outcome measures such as preservation of visual acuity as well as morphological outcome measures such as regression of CNV in angiography.

The safety and tolerability of ranibizumab will be investigated as well. As it has been tested on large numbers of patients suffering from age-related macular degeneration with only rare significant side effects or adverse events being reported, a good safety profile is assumed.

The study is conducted in a non-randomized, uncontrolled prospective setting at one center.

Patients will receive monthly injections over a period of one year.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Intravitreal injection ranibizumab in people with Choroidal Neovascularization, run by University Hospital, Bonn at 1 site in Germany.

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 6 inclusion and 18 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 15 Jun 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 Germany. 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 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?

Best corrected visual acuity (time frame: one year). 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 NCT00510965, 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 15 Jun 2012.
