About this study
Official title: Pilot Study to Evaluate the Safety and Efficacy of Oral Therapy With Postbiotics in Patients With Geographic Atrophy Secondary to Age-Related Macular Degeneration, Myopia, or Angioid Streaks
A pilot study to evaluate the safety and efficacy of oral therapy with Postbiotics in patients with geographic atrophy secondary to age-related macular degeneration, myopia, or angioid streaks.
Read the detailed description
A pilot study to evaluate the safety and efficacy of oral therapy with Postbiotics in patients with geographic atrophy (GA) secondary to age-related macular degeneration, myopia or angioid streaks.
The study's main objective is to evaluate if oral postbiotic therapy will induce epigenetic factors that would impact the progression of the GA, and it will compare the rate of growth of GA from the Baseline to 12 months, to the rate shown during the 12 months before Baseline.
- Being tested
- postbiotics (IGENH35.3A), vitamins (AREDS formulation and recommended daily dose)
- Keywords
- postbiotics, microbiota, microbiome, geographic atrophy, atrophic AMD, AMD, age-related macular degeneration
- Medical subject headings
- Geographic Atrophy, Macular Degeneration

What is being measured
The primary outcome is the main question the study is designed to answer.
rate of growth of geographic atrophy (GA) as per SQRT (square roor transformation) of area of GA measured in FAF, (fundus autofluorescence)

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 3 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: status not confirmed, as of the sponsor's last update on 24 Jun 2022. 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 Spain. 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?

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?
rate of growth of geographic atrophy (GA) as per SQRT (square roor transformation) of area of GA measured in FAF, (fundus autofluorescence) (time frame: 12 months). The study lists 2 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 24 Jun 2022; AzTrials last refreshed its copy on 6 Nov 2026.
