Trial summary

Given the aging population who will be affected by wet AMD and lack of effective GA treatment, it is crucial to assess the safety profile of repeated ranibizumab injections in AMD patients with GA, particularly the possible risk of GA development and enlargement. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 50 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients with both dry and wet-AMD

Who may be able to join

  • Age > 50 years old
  • Patients with pre-existing GA secondary to AMD NOT requiring intravitreal injections (i.e. Dry AMD)
  • Patients with pre-existing GA and CNV secondary to AMD requiring intravitreal injections (i.e. Exudative AMD) and are treatment-naïve patients
  • Patients with pre-existing GA and CNV secondary to AMD requiring intravitreal injections (i.e. Exudative AMD) and have received previous intravitreal injections.
  • Able to maintain steady fixation in foveal and parafoveal area for fundus imaging Geographic atrophy (GA), both foveal-sparing and foveal GA. Foveal-sparing GA is defined as no GA within 250μm of the centre (Sunness et al. 1999)
  • Area of GA can be imaged in its entirety and is not contiguous with areas of peripapillary atrophy
  • Adequate media clarity for quality fundus images

Who cannot join

  • Inability to undergo study procedures (e.g. contraindications to intravitreal injections) or attend follow-up visits CNV attributable to other causes than AMD
  • Active intraocular inflammation

About this study

Official title: Progression of Geographic Atrophy and Intravitreal Injections of Ranibizumab Among Treated for Age-related Macular Degeneration

Given the aging population who will be affected by wet AMD and lack of effective GA treatment, it is crucial to assess the safety profile of repeated ranibizumab injections in AMD patients with GA, particularly the possible risk of GA development and enlargement. This potential adverse effect has significant implication in the discussions with patients regarding the risks and benefits of AMD treatment and injection frequency. While monthly injections provide slight improvement of visual acuity at 2 years (Martin et al., 2012), the risk of GA enlargement may offset this benefit in visual acuity.

Previous studies assessed the association between intravitreal ranibizumab injections and de novo GA development in injection-naïve eyes (Martin et al, 2012, Querques et al., 2012., Grunwald et al., 2014), rather than GA enlargement in patients with preexisting GA. To the best of the investigators knowledge, there has been no prospective study assessing the association between intravitreal ranibizumab injections and rate of GA progression in patients with pre-existing GA. There is also no prospective study comparing the morphological features of GA between patients who are receiving intravitreal injections and those who are not, nor the concordance of GA enlargement rate between the 2 eyes among patients receiving and not receiving treatment.

What participants receive

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

  • RanibizumabDrug

    The medication Ranibizumab is routine standard of care for patients with wet AMD, and this is not an aspect of the study that is considered novel intervention

What is being measured

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

  1. Geographic atrophy area progression

    To assess the association between rate of geographic atrophy (GA) progression in age-related macular degeneration (AMD) and repeated intravitreal ranibizumab injections

    Measured: Every 6 month for total of 2 years

Secondary outcomes (2)
  1. Geographic atrophy morphological characteristics

    To determine the difference of GA morphological characteristics between AMD patients receiving intravitreal injections and those who are not

    Measured: Every 6 month for total of 2 years

  2. Concordance of GA enlargement rate between the two eyes

    To determine the concordance of GA enlargement rate between the two eyes for patients with bilateral GA

    Measured: Every 6 month for total of 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Age-related Macular Degeneration and Geographic Atrophy, run by University Health Network, Toronto at 1 site in Canada.

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 7 inclusion and 3 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 26 Feb 2015. 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 Canada. 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.

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 Crystal Cheung, MD (416-603-5376, cheuncsy@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Geographic atrophy area progression (time frame: Every 6 month for total of 2 years). 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 26 Feb 2015.
