About this study

Official title: Relative Efficacy of Loteprednol (Lotemax®) vs. Loteprednol/Tobramycin (Zylet®) in Treatment of Chronic Ocular Surface Inflammation Associated With Meibomian Gland Dysfunction (MGD)/Posterior Blepharitis

This is a Phase IV, single site, randomized, double masked, parallel control clinical trial of 60 subjects to investigate the variance of efficacy between Lotemax® and Zylet® for treatment of ocular surface inflammation due to meibomian gland dysfunction (MGD). Efficacy will be measured by in-vivo confocal microscopy, corneal fluorescein staining, grading of meibomian gland dysfunction and validated ocular symptom assessment questionnaire.

Read the detailed description

Posterior blepharitis is a common chronic eyelid condition that is described as generalized inflammation of the posterior lid margin and associated with inflammation of the ocular surface and with symptoms of burning, irritation, and discomfort. Posterior blepharitis is associated with various disorders of the meibomian glands, known collectively as meibomian gland dysfunction (MGD). It is associated either with obstruction and inflammation of the meibomian glands or, less commonly, atrophy of the meibomian glands.

Clinically, MGD often presents with inspissated meibomian glands, oily tear film, as well as inflammation and vascularization of the meibomian gland orifices. Papillary hypertrophy of the tarsal conjunctiva and corneal punctate epitheliopathy are often present, and there are prominent associations with dermatoses, such as acne rosacea, seborrhoeic dermatitis, and atopic dermatitis. Evidence from several sources suggests that MGD of sufficient extent and degree is associated with a deficient tear lipid layer, an increase in tear evaporation, and the occurrence of an evaporative dry eye. In fact MGD is considered to be the most common cause of evaporative dry eye. Individuals with MGD often complain of significant discomfort, including burning, itching, irritation, and photophobia. They may also have other associated symptoms of dry eye and may be plagued by blurred vision, gradual contact lens intolerance. Furthermore, these patients may become functionally handicapped by the negative impact of dry eye on their crucial daily activities such as working, reading, using computer, and driving.

Despite the high incidence of posterior blepharitis, there is currently no consistently effective treatment for this condition and it still remains a therapeutic challenge. Posterior blepharitis has traditionally been managed with eyelid hygiene, topical antibiotics (erythromycin or bacitracin ointments), oral tetracyclines (tetracycline, doxycycline, or minocycline) and corticosteroids which are often time consuming, frustrating, and frequently ineffective or variably effective.

The purpose of this study is to compare the effectiveness of topical loteprednol (corticosteroid) vs. the combination of loteprednol and tobramycin (corticosteroid and antibiotic) against an artificial tear. It is critical to determine to what extent the addition of an antibiotic to a topical steroid can enhance the therapeutic efficacy of the treatment.

ZyletActive comparatorSubject randomized to this arm will be treated with Zylet (Loteprednol/tobramycin), twice a day, for 4 weeks. Zylet is a combination of loteprednol and tobramycin. Loteprednol is in a class of drugs called corticosteroids. Loteprednol inhibits processes in the body that cause inflammation. Tobramycin is an antibiotic.

What is being measured

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

  1. Ocular Surface Disease Index

    OSDI is a 12-question survey used to measure the symptoms of dry eye disease. Each of the 12 individual questions rate one symptom on a 0-4 scale, with 4 meaning that the symptom is present all of the time and 0 meaning the symptom is present none of the time. The overall ODSI score is calculated by adding all of the values from the 12 questions, multiplying that value by 25, and dividing the resulting value by the number of questions answered. This results in an overall scale that ranges from 0-100, with 100 being severe dry eye symptoms and 0 being no dry eye symptoms.

    Measured: Week 4 Time Point

  2. Symptom Assessment iN Dry Eye (SANDE) Frequency Score

    Questionnaire given to patients to assess the frequency of dry eye symptoms. The questionnaire utilizes a 100 mm horizontal Visual Analogue Scale technique to quantify the frequency of the patient's dry eye symptoms. Change is quantified from baseline to week 4. The range of the SANDE frequency scale is 0-100, with 0 being the minimum level of frequency of dry eye symptoms and 100 being the maximum level of frequency of dry eye symptoms.

    Measured: Week 4 Time Point

  3. Symptom Assessment iN Dry Eye (SANDE) Severity Score

    Questionnaire given to patients to assess the severity of dry eye symptoms. The questionnaire utilizes a 100 mm horizontal Visual Analogue Scale technique to quantify the severity of the patient's dry eye symptoms. Change is quantified from baseline to week 4. The range of the SANDE severity scale is 0-100, with minimum level of severity of dry eye symptoms and 100 being the maximum level of severity of dry eye symptoms.

    Measured: Week 4 Time Point

  4. Corneal Fluorescein Staining Score

    Corneal Fluorescein Staining is used to assess the level of corneal epitheliopathy that is related to dry eye disease. The CFS scale ranges from 0 to 15 scale, with 0 representing the minimum level of corneal epitheliopathy and 15 representing the maximum level of corneal epitheliopathy.

    Measured: Week 4 Time Point

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 12 inclusion and 14 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 Aug 2017. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Jun 2017). 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?

Ocular Surface Disease Index (time frame: Week 4 Time Point). The study lists 4 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 Aug 2017.
