About this study

Official title: Comparison of Autologous Serum 20% and Autologous Serum 50% for the Treatment of Severe Dry Eye

Read the detailed description

To determine the difference between autologous serum 20% vs 50%, in terms of improvement of symptoms, improvement of ocular surface parameters and acceptable tolerability in patients with severe dry eye syndrome.

What is being measured

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

  1. Change in Ocular Surface Disease Index (OSDI) Score

    The Ocular Surface Disease Index (OSDI) is a 12-item questionnaire designed to provide a rapid assessment of the symptoms of ocular irritation consistent with dry eye disease and their impact on vision-related functioning.

    The overall OSDI score defines the ocular surface as normal (0-12 points) or as having mild (13-22 points), moderate (23-32 points), or severe (33-100 points) disease.

    Measured: 1 month

Secondary outcomes (4)
  1. Change in Tear Break Up Time (TBUT)

    The TBUT is based on the time of tear rupture after the instillation of fluorescein.

    The shorter the time of rupture, the greater the tear dysfunction

    Measured: 1 week, 1 month, 2 months

  2. Change in Oxford Staining score

    The Oxford scale is based on the amount of ocular surface (cornea and conjunctiva) that is stained with lysine or green fluorescein. The severity of the staining points is classified into 6 stages (0-5) from absent to marked epithelial damage.

    Measured: 1 week, 1 month, 2 months

  3. Change in Schirmer I

    It is a tear production test. The Schirmer I test is performed without anesthesia. Two thin strips of filter paper (Whatman 5mm x 35mm) are placed on the bottom of the lower conjunctival sac at the junction of the middle third and the outer third to prevent injury to the cornea. It is recommended to ask the subject to keep their eyes closed to limit the effect of blinking. The strips are kept positioned for 5 minutes and then they are removed and the amount that was moistened is read, in mm.

    The lower the value, the greater the deficit of tear production

    Measured: 1 week, 1 month, 2 months

  4. Change in Ocular Surface Disease Index (OSDI) Score

    The Ocular Surface Disease Index (OSDI) is a 12-item questionnaire designed to provide a rapid assessment of the symptoms of ocular irritation consistent with dry eye disease and their impact on vision-related functioning.

    The overall OSDI score defines the ocular surface as normal (0-12 points) or as having mild (13-22 points), moderate (23-32 points), or severe (33-100 points) disease.

    Measured: 1 week, 2 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Autologous Serum 20% and Autologous Serum 50% in people with Dry Eye and Keratoconjunctivitis Sicca, run by Pontificia Universidad Catolica de Chile at 1 site in Chile.

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 6 inclusion and 7 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 5 Sep 2018. 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 Chile. 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?

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 Ocular Surface Disease Index (OSDI) Score (time frame: 1 month). 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 5 Sep 2018.
