Study groupRoleWhat they receive
Patients with a Geographic Atrophy diagnosisPatients diagnosed with geographic atrophy (GA) in at least one eye, at least 50 years old with information on laterality, and registered in the Vestrum health database between January 2015 and April 2023.

What is being measured

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

  1. Change in Visual Acuity (VA) in Participant's Study Eye

    Change in visual acuity (VA) in participant's study eye is reported. Study eye is defined as the first eye with the disease, and fellow eye, the participant's second eye. Change in VA was determined by calculating the difference between mean visual acuity (VA) readings at index diagnosis, and mean at another timepoint, assessed yearly for participants with valid VA readings at both timepoints.

    Measured: From index date of GA diagnosis up to 5 years

  2. Number of Participants Who Developed or Progressed to Age-related Macular Degeneration (wAMD) in the Study Eye

    Number of participants who developed or progressed to age-related macular degeneration (wAMD) in the study eye is reported. The criteria used to determine progression through development to wAMD was identifying when ICD (International Classification of Diseases) codes for wAMD were present in the study eye.

    Measured: From index date of GA diagnosis up to 5 years.

  3. Number of Participants Who Developed or Progressed to Geographic Atrophy (GA) in the Fellow Eye

    Number of participants who developed or progressed to geographic atrophy (GA) in the fellow eye is reported. For patients diagnosed with GA at baseline, the development of GA in the fellow eye was closely monitored over time, with progress tracked for each year.

    Measured: From index date of GA diagnosis up to 5 years.

  4. Change in Lesion Location for Participants With wAMD in Study Eye

    Change in lesion location from extrafoveal to subfoveal in participants who developed wAMD in study eye is reported. Lesion location was assessed at index diagnosis and at each year, then stratified by whether a patient developed wAMD in the 5 years post diagnosis. Changes in lesion were calculated as the difference in the number of participants with extrafoveal location at index diagnosis of the study eye, compared to the number of participants with extrafoveal lesion in the study eye at each year.

    Measured: From index date of GA diagnosis up to 5 years

  5. Change in Lesion Location for Participants With GA in Fellow Eye

    Change in lesion location from extrafoveal to subfoveal in participants who developed GA in fellow eye is reported. Lesion location was assessed at index diagnosis and at each year, then stratified by whether a patient developed GA in the 5 years post diagnosis. Changes in lesion were calculated as the difference in the number of participants with extrafoveal location at index diagnosis of the study eye, compared to the number of participants with extrafoveal lesion in the study eye at each year.

    Measured: From index date of GA diagnosis up to 5 years

  6. Occurrence of GA Over Study Period

    Incidence and prevalence of GA over time is reported. This endpoint analyzed the yearly counts of newly diagnosed or prevalent cases to help in understanding the progression of the overall disease.

    Measured: Number of yearly counts of GA from 2018 to 2013, by quarterly average.

Secondary outcomes (6)
  1. Retinal Disease-related Outcomes: Number of Visits Per Quarter in a Year

    The retinal disease-related healthcare resource utilization (HCRU) outcome, number of visits by participants per quarter in a year is reported.

    Measured: Mean number of quarterly visits from 2019 up to 2023.

  2. Retinal Disease-related Outcomes: Number of Anti-VEGF Injections Per Quarter

    The retinal disease-related healthcare resource utilization (HCRU) outcome, number of anti-vascular endothelial growth factor (anti-VEGF) injections per quarter in a year is reported.

    Measured: Mean number of quarterly anti-VEGF injections from 2019 up to 2023.

  3. Retinal Disease-related Outcomes: Number of Participants With Ocular Comorbidities by Year of Follow up

    The retinal disease-related HCRU outcome, number of ocular comorbidities by year of follow up is reported.

    Measured: Total number of participants with ocular comorbidities were documented from index date up to 5 years.

  4. HCRU Outcome: Number of Participants With the Medical Procedure of Corneal Transplant

    The number of participants with corneal transplant during the observational period is reported.

    Measured: Total number of participants with corneal transplants were documented from index date up to 5 years.

  5. HCRU Outcome: Number of Participants With the Medical Procedure of Incisional Glaucoma Surgery

    Number of participants with incisional glaucoma surgery during the observational period is reported.

    Measured: Total number of participants with incisional glaucoma surgery were documented from index date up to 5 years.

  6. HCRU Outcome: Number of Participants With the Medical Procedure of Vitrectomy

    Number of participants with vitrectomy during the observational period is reported.

    Measured: Total number of participants with vitrectomy were documented from index date up to 5 years.

Individual data sharing
No: Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).

Questions about this trial

What is this clinical trial studying?

An observational study of Geographic Atrophy, run by Boehringer Ingelheim at 1 site in United States.

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 1 inclusion and 1 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 1 May 2025. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 May 2025). 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?

Change in Visual Acuity (VA) in Participant's Study Eye (time frame: From index date of GA diagnosis up to 5 years). The study lists 6 primary outcomes in all. 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 1 May 2025.
