About this study

Official title: A Randomized Observer and Subject Masked Trial Comparing the Visual Outcome After Treatment With Ranibizumab or Bevacizumab in Patients With Neovascular Age-related Macular Degeneration Multicenter Anti VEGF Trial in Austria (MANTA)

Angiogenesis plays a key role in the development of choroidal neovascularizations (CNV) in age-related macular degeneration. Vascular endothelial growth factor (VEGF) is the most important factor involved in this angiogenetic processes in the eye. This forms the basis for new therapeutic interventions in exudative AMD. Currently two drugs have been approved by the FDA and one drug is used off-label. All these drugs are administered intravitreally. The present study aims to directly compare the effects ranibizumab and bevacizumab in a randomized controlled study in patients with neovascular AMD.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ranibizumab and Bevacizumab in people with Age Related Macular Degeneration, run by The Ludwig Boltzmann Institute of Retinology and Biomicroscopic Laser Surgery at 1 site in Austria.

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 2 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 9 Jun 2010. 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 Austria. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Ilse Krebs, MD (43-17-1165 ext. 94682, Ilse.Krebs@wienkav.at), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of visual acuity over time (time frame: 12 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 NCT00710229, 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 9 Jun 2010.
