Brief summary

The objective of this study is to compare the safety and efficacy of BRM421 Ophthalmic Solution to placebo for the treatment of the signs and symptoms of dry eye.

Detailed description

This is a multi-center, double-masked, randomized, vehicle-controlled, phase 2 study in approximately 150 subjects. (75 per treatment arm).

Inclusion criteria

* Be at least 18 years of age; * Provide written informed consent; * Have a reported history of dry eye for at least 6 months prior to enrollment; * Have a history of use of eye drops

Exclusion criteria

* Have any clinically significant slit lamp findings at Visit 1 that may include active blepharitis, meibomian gland dysfunction (MGD), lid margin inflammation or active ocular allergies that require therapeutic treatment, and/or in the opinion of the investigator may interfere with study parameters; * Be diagnosed with an ongoing ocular infection (bacterial, viral, or fungal), or active ocular inflammation at Visit 1; * Have worn contact lenses within 7 days of Visit 1 or anticipate using contact lenses during the study; * Have used any eye drops within 2 hours of Visit 1; * Have previously had laser-assisted in situ keratomileusis (LASIK) surgery within the last 12 months; * Be a woman of childbearing potential who is not using an acceptable means of birth control; acceptable methods of contraception

Design outcomes

Primary

MeasureTime frameDescription
Sign: Corneal Fluorescein Staining Scorechange from baseline to week 4The staining was graded with the Ora Calibra® Corneal and Conjunctival Staining Scale. The ocular surface was divided into three regions, including superior, central and inferior region. The following scale was used to grade staining of the each region. Half (0.5) grade increments may be used. The total score of corneal fluorescein staining was calculated as the sum of three regions, the score range is 0 (minimum) to 12 (maximum). None 0 = no staining Trace 1 = occasional Mild 2 = countable Moderate 3 = uncountable, but not confluent Severe 4 = confluent
Symptom: Ocular Discomfort Scorechange from baseline to week 4Ocular discomfort scores was subjectively graded by the subjects according to the following Ora Calibra® Ocular Discomfort Scale, rating each eye separately, the score range is 0 (minimum) to 4 (maximum). 0 = no discomfort 1. = intermittent awareness 2. = constant awareness 3. = intermittent discomfort 4. = constant discomfort

Secondary

MeasureTime frameDescription
Tear Film Break-up Timechange from baseline to week 4The examiner was instilled 5 uL of 2% preservative-free sodium fluorescein solution into the inferior conjunctival cul-de-sac of each eye. With the aid of a slit-lamp, the examiner monitored the integrity of the tear film, noting the time (seconds) it takes to form micelles from the time that the eye is opened.
Conjunctival Rednesschange from baseline to week 4Conjunctival redness was graded according to the following scale: Half (0.5) unit increments may be used. None 0 = Normal, without vasodilation Trace 1 = Trace ciliary or conjunctival vasodilation Mild 2 = Broad ciliary vasodilation; Moderate 3 = Broad ciliary and slight, horizontal conjunctival vasodilation Severe 4 = Broad ciliary and prominent, horizontal conjunctival vasodilation
Ocular Surface Disease Index (OSDI)©change from baseline to week 4OSDI scores was subjectively graded by the subjects according to the Ocular Surface and Disease Index (OSDI) Scale. Patients scored each question from 0 to 4 (higher score means more severe), and the OSDI score is the sum of total 12 questions. The score range is 0 (minimum) to 48 (maximum).
