A Study of Safety and Efficacy of UNR844 Chloride (UNR844-Cl) Eye Drops in Subjects With Presbyopia.

A 3-month, Randomized, Placebo-controlled, Double-masked, Multi-center Study to Evaluate the Safety and Efficacy of Topical Ocular UNR844-Cl in Subjects With Presbyopia

The purpose of this study was to assess the effect of topical UNR844-Cl (lipoic acid choline ester chloride) ophthalmic solution on near visual function in presbyopic subjects.

This was a multi-center, double-masked, placebo-controlled, randomized, parallel-group study. The total duration of the study was approximately 3 months. Approximately 120 presbyopic subjects were to be enrolled into the study. Presbyopic subjects aged 45 to 55 years were the primary age group in this study. Screening and Baseline: Subjects were screened for eligibility followed by a baseline visit after which they were randomized to receive either UNR844-Cl (1.5%, equivalent to 1.3% freebase) or Placebo, dosed one drop in each eye twice daily, for 3 months. Randomized subjects attended the following study visits after baseline: at Week 2, Month 1, Month 2 and Month 3. The primary objective of this study was to assess the efficacy of UNR844-Cl on binocular distance corrected near visual acuity (DCNVA) in presbyopic subjects aged 45 to 55 years with the primary endpoint being the change from baseline in binocular DCNVA in subjects aged 45 to 55 years at Month 3 after UNR844-Cl or Placebo treatment. There were two secondary endpoints: To assess the efficacy of UNR844-Cl on achieving 75 or more Early Treatment Diabetic Retinopathy Study (ETDRS) letters in binocular DCNVA in presbyopic subjects aged 45 to 55 years with endpoint being the proportion of subjects aged 45 to 55 years achieving 75 or more ETDRS letters in binocular DCNVA at Month 3 after UNR844-Cl or Placebo treatment. To assess the safety of UNR844-Cl in presbyopic subjects by the frequency of treatment emergent adverse events (AEs) and treatment emergent serious adverse events (SAEs) in all subjects after UNR844-Cl or Placebo treatment.

Change from baseline in binocular DCNVA in subjects aged 45 to 55 years at Month 3 after UNR844-Cl or placebo treatment. Low contrast (10% contrast) DCNVA at 40 cm is measured binocularly using an electronic visual acuity testing system. This assessment was performed with subjects corrected for any distance refractive errors. The system provided distance-corrected low contrast near visual acuity in an Early Treatment Diabetic Retinopathy Study (ETDRS) letter numerical score. High monocular DCNVA ETDRS letter scores represent good vision; Low monocular DCNVA ETDRS letter scores represent poor vision.

Number and Percentage of Subjects Aged 45 to 55 Years Achieving 75 or More Early Treatment Diabetic Retinopathy Study (ETDRS) Letters in Binocular DCNVA at Month 3

Change from baseline in binocular DCNVA in subjects aged 45 to 55 years at Month 3 after UNR844-Cl or placebo treatment. Low contrast (10% contrast) DCNVA at 40 cm is measured binocularly using an electronic visual acuity testing system. This assessment was performed with subjects corrected for any distance refractive errors. The system provided distance-corrected low contrast near visual acuity in an Early Treatment Diabetic Retinopathy Study (ETDRS) letter numerical score. High monocular DCNVA ETDRS letter scores represent good vision; Low monocular DCNVA ETDRS letter scores represent poor vision.

Number of Subjects With Adverse Events, Ocular Adverse Events, Deaths, Other Serious Adverse Events, or Adverse Events Leading to Study Drug Discontinuation

Frequency of treatment emergent adverse events and treatment emergent serious adverse events in all subjects. Adverse events were collected from first dose of study treatment until end of study treatment plus 30 days post treatment, up to a maximum duration of 120 days.

Inclusion Criteria: Written informed consent must be obtained before any assessment is performed Impaired near vision in each eye and when using both eyes, without any near correction Need a certain level of near correction Exclusion Criteria: Impaired distance vision in either eye, with distance correction (if any) Severe short- or long-sightedness Any significant medical or clinical conditions affecting vision, the eyes or general health
