Filter by:This study will evaluate the safety, efficacy, tolerability, and systemic pharmacokinetics of 3 different doses of topical ophthalmic AGN-223575 suspension compared to AGN-223575 vehicle in patients with dry eye disease.
Dry eye is a chronic irritating eye condition that affects many people, caused by poor tear quality and insufficient quantity. Treatments are traditionally in the form of artificial tears applied to the ocular surface. However, there is little evidence in the scientific literature that demonstrates their efficacy relative compared to each other, nor how to decide which one might be most effective for an individual patient. Therefore the investigators aim to examine the efficacy of different classes of artificial tears (those designed to increase viscosity, reduce evaporation or to mimic the component balance of the natural tears). In addition, the investigators also aim to determine how the treatment preferred by an individual could potentially have been predicted from their baseline condition.
This study will examine the safety, tolerability, and systemic pharmacokinetics of up to 3 different concentrations of AGN-232411 topical ophthalmic solution in healthy participants and participants with dry eye.
Millions of people suffer from dry eye disease, causing symptoms such as redness, burning, feeling of sand or grit in the eye and light sensitivity. Dry eye disease occurs when your eyes do not produce enough tears or produce poor quality tears. This can happen for a number of reasons, including aging, hormonal changes in women and side effects of diseases or medications. It is now possible to objectively measure the degree of dry eye disease by collecting a tiny sample of tears from the corner of the eye and then measuring the amount of salt in the tears (termed osmolarity). We aim to establish the overall levels of raised and normal tear osmolarity in people presenting to the eye clinic with complaints of dry eye, and relate this to other factors such as symptoms, topical and nutritional medication and dry eye treatment.
This is a prospective, comparative, contralateral eye study. Patients older than 18 years who have had treatment with topical lubricants for at least 1 month and persist with symptoms of dry eye and corneal staining with fluorescein were included. Patients with dry eye attributable to abnormalities of the eyelids, nasolacrimal obstruction and active corneal infection, as well as patients with severe dry eye were excluded from the study. One eye randomly received a subcutaneous injection of botulinum toxin in the medial part of the lower eyelid, and the other eye received a similar procedure with placebo. The subjective evaluation was achieved with a questionnaire assessing symptoms of dry eye and conjunctivitis, quality of vision and ocular comfort level each eye separately. The objective evaluation included the measurement of the tear film break up time, Schirmer's test and with a modification of the Oxford grading scheme for corneal and conjunctival staining.
The objectives of this study are: - To compare the change in levels of tear proteins and inflammatory mediators pre and post administration between the intranasal and extranasal applications - To compare the goblet cell count following application between the intranasal and extranasal applications - To compare fluorescein tear clearance with the application of the device intranasally and extranasally applications
The purpose of this study is to evaluate the efficacy and safety of Systane® Gel Drops in dry eye subjects following 90 days of QID (4 times/day) dosing.
The investigators aim to assess the effect of blepharoplasty with or without muller muscle resection on the symptoms of dry eye syndrome. this will be an observational study in which patients undergoing the aforementioned surgeries will be followed up and monitored for dry eye symptoms.
Subjects with moderate-to-severe Dry Eye by symptoms will be screened including history, ophthalmic examination to include the status of their ocular structure and function and evaluation of tear production. Blood will be blood drawn for complete blood count and chemistry panel. They will also have a urinalysis and pregnancy test in women of child-bearing potential. Subjects will have a two week "run-in" period in which they use artificial tears. If their Dry Eye signs and symptoms do not improve significantly, they will be enrolled and will receive study drug. Safety evaluation includes assessment of the structure and function of the eyes including retina examination and corrected visual acuity. Subjects who meet the inclusion and exclusion criteria will be randomly assigned to one of two treatment arms, ST266 or "artificial tears" eye drops. The randomization scheme is 1:1 ST266:artificial tears. Subjects will self-administer their eye drops four times each day. Subjects will be seen in the office of the ophthalmologist/optometrist at baseline (week zero), one week, three weeks, six weeks and ten weeks. Eye examination will be done at each visit. The baseline eye tests and lab work will be repeated after the treatment phase of the study at the end of week six. Following 6 weeks of treatment, the subjects will be followed for 4 additional weeks.
The purpose of this study is to evaluate the efficacy of LME636 compared to vehicle in the reduction of ocular symptoms and to evaluate the safety and tolerability of LME636, when administered topically for up to 42 days, in subjects with severe dry eye disease.
