About this study

Official title: "In Vivo Evaluation of Topical Ocular Use of Autologous Serum Obtained by a Closed-Circuit Collection Device."

Autologous serum eye drops (ASED) are an established therapy for ocular surface diseases; however, their preparation can be costly and may not be available due to the need for germ-free conditions. This pilot trial assesses the feasibility of collecting ASED in a closed-circuit system for patients with chronic ocular surface diseases.

Read the detailed description

Autologous Serum exhibits characteristics very similar to those of tears, such as pH, osmolarity, vitamins, and Immunoglobulin A. It also contains growth factors, nutritional factors, and antibacterial components that are necessary for the maintenance of cellular viability in the epithelial repair process. The use of autologous serum eye drops was first described in 1984 by Fox et al., in research for a preservative-free tear substitute. Subsequently, in 1999, Tsubota et al. found that, due to the presence of growth factors and vitamins, autologous serum could have a true epithelial trophic potential for the ocular surface. The autologous serum eye drops are not only a lubricant for the ocular surface but also provide various essential substances for the reconstruction of epithelial damage, including vitamin A, epithelial growth factor, fibronectin, and a variety of cytokines. With these epithelial trophic factors, autologous serum facilitates proliferation, migration, and differentiation of the ocular surface epithelium. Moreover, it is known for its anti-catabolic properties, inhibiting the inflammatory cascade triggered by interleukin-1, which prevents tissue destruction. Therefore, autologous serum eye drops have been effective in the treatment of persistent epithelial defects, neurotrophic ulcers, superior limbic keratoconjunctivitis, dry eye conditions, graft-versus-host disease (GVHD), or after refractive surgeries, such as LASIK (Laser Assisted In Situ Keratomileusis). In 2020, Wang et al. published an article with 7 randomized controlled trials comparing the use of autologous serum versus artificial tears in patients with dry eye syndrome. In the meta-analysis, all 7 studies evaluated subjective symptoms and showed that autologous serum eye drops were superior to ocular lubricants in alleviating and remitting symptoms. It was shown that autologous serum eye drops significantly improved parameters such as OSDI (Ocular Surface Disease Index), tear break-up time, and Bengal Rose staining when compared to the control group using ocular lubricants. Given the numerous properties of autologous serum eye drops, there is no doubt about their benefit and effectiveness in treating several ocular surface diseases, including ocular GVHD. However, the difficulty in accessing production and the substantial cost of autologous serum eye drops are the main challenges, and their use is often limited to more severe dry eye cases and those refractory to conventional treatment.

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 10 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: under way, not looking for participants, as of the sponsor's last update on 21 Oct 2026. 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 Brazil. 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?

This study is still under way. Results are not available in the source record yet.

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?

Feasibility of using the collection device under testing (time frame: 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 21 Oct 2026.
