About this study

Official title: A Clinical Evaluation of the RPS InflammaDry Detector's Sensitivity and Specificity Compared to the Clinical Diagnosis for Confirming Dry Eyes.

The RPS InflammaDry Detector™ is intended to detect elevated MMP-9 in human tears to aid in the diagnosis of patients with signs or symptoms of dry eye disease, in conjunction with other methods of clinical evaluation.

Read the detailed description

The purpose of this clinical trial was to determine the sensitivity and specificity of InflammaDry compared with the clinical assessment of dry eyes.

Patients were screened using clinical history and signs.

Clinical history was performed using the Ocular Surface Disease Index (OSDI) and evaluated for clinical signs:

  • positive vital staining of the ocular surface,
  • decreased tear breakup time (TBUT),
  • reduced corneal sensitivity, and
  • decreased functional visual acuity Last, an independent health care professional masked to the clinical evaluation was asked to analyze each InflammaDry test result, independently confirming each result.

What is being measured

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

  1. Sensitivity and Specificity of InflammaDry Detector Compared to Clinical Assessment at Confirming a Diagnosis of Dry Eyes.

    Patients were assessed for signs and Symptoms of Dry Eye using OSDI (Ocular Surface Disease Index), TBUT (Fluorescein Tear Break-up Time), Corneal fluorescein staining and Schirmer Tear Test and compared to the results of the tested device.

    Sensitivity is the percentage of true positive cases correctly identified by the test, compared to clinical assessment.

    Specificity is the percentage of true negative cases correctly identified by the test, compared to clinical assessment.

    Measured: 15 minutes

Questions about this trial

What is this clinical trial studying?

An observational study of Dry Eye, run by Rapid Pathogen Screening at 8 sites 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 16 inclusion and 9 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 12 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites 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 16 Mar 2022). 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?

Sensitivity and Specificity of InflammaDry Detector Compared to Clinical Assessment at Confirming a Diagnosis of Dry Eyes. (time frame: 15 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01313351, which also lists 1 linked publication.

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 12 Dec 2022.
