May 8, 2017 updated by: Laboratorios Sophia S.A de C.V.

A Randomized, Double-blind, Phase III Clinical Trial to Evaluate the Efficacy and Safety of PRO-148 Versus Systane®, in Patients With Mild to Moderate Dry Eye

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Dry eye is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. Current treatment is heavily weighted toward supplementation, stimulation, or preservation of aqueous tears. Artificial tears are one of the primary treatments for dry eye; it is mainly palliative and focuses on reducing the symptoms of discomfort to improve quality of life for a patient.

A phase III randomized double-blind clinical trial will be conducted to evaluate efficacy and safety of the ophthalmic solution PRO-148 in the ocular surface of patients with mild to moderate dry eye compared with ophthalmic solution Systane®. Patients will be randomized to receive one of the treatments for 60 days. Efficacy and safety measures will be performed at baseline and at 60 days after treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Ocular Surface Disease Index (OSDI©) Questionnaire
Time Frame: Day 60
Ocular Surface Disease Index (OSDI©) questionnaire , consists of 12 questions divided in 3 groups, Each question has a value that can go from 0 to 4 points according to the severity of the case: 0.None of the time, 1. Some of the time, 2.Half of the time, 3.most of the time and 4 all of the time. The points of all the questions will be used in the following formula for converted to a score of 0-100 : (sum of scores) x 25 / (# of questions answered), where 0 represents normality or non-symptomatology and 100 the most severe case. Will be used to measure the symptoms of dry eye disease by obtaining baseline data and comparing them against the last visit.
Day 60

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Schirmer Test
Time Frame: Day 60

Change from Baseline in Schirmer test after 60 days of treatment

Schirmer test

It is the technique most used to measure aqueous and at the same time the simplest tear secretion. It is carried out as follows: Without applying anesthesia, the patient is placed somewhere without much illumination, without applying anesthesia, a strip of filter paper of approximately 30 mm is placed, of which, 5 mm must go in the joint Of the middle and outer third of the lower eyelid. The patient is instructed to look forward and to blink normally. After 5 minutes the strips are removed and the wetting is recorded in millimeters. A test less than or equal to 6 mm is diagnostic of aqueous deficiency.The mean of the revisions by group will be compared at the baseline and final visit.
Day 60
Tear Film Break up Time
Time Frame: Day 60
Change from Baseline in Tear film break up time after 60 days of treatment Tear film breakup time is the elapsed time from blinking to the first occurrence of a dry area in the cornea, visualized with the help of fluorescein staining. Measurement of tear film breakup time will be performed as follows: Fluorescein is instilled in the eye, the patient is asked to blink three times to distribute the dye and then set the eye to the front and do not blink while the examiner observes the cornea with cobalt blue light, looking for an area of tear film rupture, which is manifested by the appearance of a black island within the fluorescein green film. Normally film breakup time is 10 seconds or more and the minimum register may be 1 second, Under 10 seconds is considered abnormal.
