Latanoprost Versus Tafluprost: 24-hour Intraocular Pressure (IOP) (SAF-24H-IOP)

May 5, 2013 updated by: Luciano Quaranta, MD, Azienda Socio Sanitaria Territoriale degli Spedali Civili di Brescia

Comparative Evaluation of Intraocular Pressure During the 24 Hour in Patients Affected by Primary Open-angle Glaucoma and Ocular Hypertension: Latanoprost 0.005% Versus Tafluprost 0.0015% Ophthalmic Solutions

  • Main objective is to compare the ability of Latanoprost 0.005% preservative-added ophthalmic solution versus Tafluprost 0.0015% preservative-free ophthalmic solution, both given once a day at the evening, in reducing 24-hour intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG) and/or ocular hypertension (OHT) at first diagnosis. First efficacy variable will be the difference between mean nocturnal IOP values after three months of treatment: nocturnal IOP is defined as the mean value between 2AM and 6AM measurements.
  • Secondary objectives will be the comparison between Latanoprost 0.005% and Tafluprost 0.0015% ophthalmic solution about:

    • Mean 24-hour IOP values after three months of treatment
    • IOP values at these time-points: 10AM (± 1 hour), 2PM (± 1 hour), 6PM (± 1 hour), 10PM (± 1 hour), 2AM (± 1 hour) and 6AM (± 1 hour) after three months of treatment

Description

Inclusion Criteria:

  • Past ocular surgery, except cataract surgery in the previous 6 months
  • Corneal abnormalities that can influence IOP measurements (corneal oedema)
  • Positive pregnancy test or breast-feeding woman. No will to avoid pregnancy during all the study period and in the next three months

Intervention / Treatment
Experimental: TAFLUPROST 0.0015% EYEDROPS
Tafluprost 0.0015% preservative-free ophthalmic solution will be given once a day at the evening,in patients with primary open angle glaucoma (POAG) and/or ocular hypertension (OHT) at first diagnosis. IOP values after three months of treatment will be evaluated throughout the 24-hour by the means of Goldmann and Perkins applanation tonometry.
IOP values will be assessed by the means of Goldmann or Perkins applanation tonometry at the following time-points: 10AM (± 1 hour), 2PM (± 1 hour), 6PM (± 1 hour), 10PM (± 1 hour), 2AM (± 1 hour) and 6AM (± 1 hour) after three months of treatment
