Safety and Efficacy of Liposomal Latanoprost in Ocular Hypertension

Overview

Aim: Evaluation of a single subconjunctival injection of liposomal EggPC formulation of latanoprost in treating glaucoma. Hypothesis: The investigators have already evaluated carrier stability, drug partitioning, in vitro drug release, tolerance, and efficacy of latanoprost-incorporated EggPC liposomes upon subconjunctival administration in both rabbit and monkey eyes. Therefore, the investigators hypothesize that this would be safe and efficacious in humans as well. Methodology: A pilot study to assess a liposome formulation containing latanoprost. The investigators will recruit 6 study subjects with eyes that have raised IOP, for subconjunctival injection of this liposome formulation. The recruited eye will be injected and monitored for inflammation, toxicity and pain as primary end-points. Monitoring of the eye will be for the first 24 hours post-injection, week 2, months 1, 2 and 3 thereafter. Importance: If proven safe, this method of drug delivery could potentially be used for treatment of raised intraocular pressures in blinding conditions such as glaucoma.

The number of recorded adverse events and intolerance to the subconjunctival injection procedure by the participants during the study period was used as a measure of safety.
