Safety Study of Latanoprost Slow Release Insert

Stopped early · Phase 1

Conditions studied: Primary Open Angle Glaucoma (POAG), Ocular Hypertension (OHT)

In brief

This study is a phase 1, open-label, dose-escalation, safety and tolerability study, which will be conducted at one study site. This study will include 3 cohorts. Each cohort will have approximately 5 subjects. Subjects will not be randomized into the study. The first cohort will receive low dose drug insert, second cohort will receive 2 low dose drug inserts thus achieving twice the drug levels compared to cohort I and third cohort will receive high dose drug insert.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male and female POAG and OHT subjects who are well controlled on mono therapy or dual therapy, who have not undergone any prior glaucoma surgeries and are not allergic or non-responders to any prostaglandin analogues, will be included in this study.
• At least 18 years old at time of consent.
• Diagnosis of primary open-angle glaucoma (including pigmentary or pseudoexfoliative glaucoma patients) or ocular hypertension in 1 or both eyes.
• IOP deemed as well controlled by investigators, with prostaglandin analogue/ prostanoid either as a monotherapy or part of dual medical therapy.
• Subjects with mild or moderate glaucoma where subjects can be without IOP lowering treatment for up to 2 months.
• Mean IOP of at least 22 mmHg in the study eye and not more than 36 mmHg in either eye at 8 AM on the baseline visit (after 4 weeks of washout).
• Mean IOP of at least 20 mmHg in the same eye that qualified at 8 AM and not more than 36 mmHg in either eye at 10 AM, 12 PM, 2 PM and 4 PM on baseline visit.
• Best Corrected Visual Acuity of 20/100 or better by Snellen's visual acuity measurement in each eye (or equivalent ETDRS Visual acuity).
• Clear ocular media with good view of optic disc and macula.
• Negative urine pregnancy test at baseline for women of childbearing potential.
• An informed consent document signed and dated by the subject or a legally acceptable representative.
• Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures

You may not qualify if…

• Closed/barely open anterior chamber angle or a history of acute angle closure (i.e., 75% of the circumference of the angle is 10° or less) in either eye.
• Subjects with diagnosis of secondary glaucoma.
• Diagnosis of a clinically significant or progressive retinal disease (e.g. diabetic retinopathy, macular degeneration) in either eye that would inhibit accurate VA testing.
• Advanced glaucoma defined by a cup/disc ratio >0.8 or a history of severe central visual field loss in either eye.
• History of intolerance and or lack of response to prostaglandin analogues.
• History of hypersensitivity to latanoprost or any other ingredient in the study drug.
• Central corneal thickness greater than 600 μm in either eye.
• Any condition that prevents reliable applanation tonometry (e.g. significant abnormalities of the corneal surface) in either eye.
• History of severe dry eye.
• Eye lid abnormalities i.e. entropion, ectropion or lower lid retraction.
• Evidence of corneal punctate staining, exposure keratopathy or keratitis, history of infectious keratitis i.e. herpes.
• History of ocular cicatricial diseases i.e. cicatricial pemphigoid, pemphigus, S-J syndrome, conjunctival scarring secondary to topical medications.
• History of endothelial dystrophy (Fuchs, corneal guttata) or corneal edema.
• History of iritis or uveitis.
• History of clinically significant aspirin intolerant asthma (AIA).
• History of any ocular surgery or trauma in either eye within 3 months of the screening visit.
• History of glaucoma filtration surgery including but not limited to Trabeculectomy, Canaloplasty, Trabectome and Glaucoma Drain surgery.
• History of ocular infection, ocular inflammation, or laser surgery in either eye within 3 months of the screening visit.
• Unable to discontinue contact lens use.
• Anticipate the need to initiate or modify medication (systemic or topical) that is known to affect IOP during the study period.
• Any severe acute or chronic medical or psychiatric condition that could increase the risk associated with study participation or could interfere with the interpretation of study results and, in the judgment of the investigator, could make the patient inappropriate for entry into this study.
• Treatment with an investigational drug or device within 30 days preceding the device placement.
• Pregnant or nursing females; females of childbearing potential who are unwilling or unable to use an acceptable method of nonhormonal contraception as outlined in this protocol from at least 14 days prior to the first dose of study medication and throughout the study.
