24-Hour Intraocular Pressure Control With Bimatoprost/Timolol Versus Latanoprost as First Choice

May 9, 2014 updated by: AGP Konstas, Aristotle University Of Thessaloniki

24-Hour Intraocular Pressure Control Obtained With the Bimatoprost/Timolol Fixed Combination Compared With Latanoprost as First Choice Therapy in Subjects With Exfoliation Syndrome, or Exfoliative Glaucoma

The primary objective of this crossover 24-hour Intraocular Pressure (IOP) trial is to compare the control obtained after 3 months of therapy with the bimatoprost/timolol fixed combination (BTFC, Ganfort) given once in the evening (20:00) versus latanoprost (Xalatan) administered once in the evening (20:00) in newly-diagnosed patients with exfoliation syndrome (XFS) and ocular hypertension, or exfoliative glaucoma (XFG) previously untreated and IOP greater than 29 mm Hg.

Description

Inclusion Criteria:

  • Patient has exfoliation syndrome with ocular hypertension, or exfoliative glaucoma and is older than 29 years
  • Patient is newly diagnosed, or currently untreated and exhibits untreated morning IOP (2 separate IOP readings at 10:00)greater than 29 mm Hg in the study eye
  • Study patients should have mild to moderate exfoliative glaucoma (VF loss <12 dB; cupping 0.8 or less)
  • Patient with exfoliation syndrome should fulfill the IOP criterion (IOP > 29 mm Hg at 10:00)
  • Patient deemed by investigator to require significant IOP reduction to obtain desired target IOP
  • Patient agrees to be treated for at least 3 months with latanoprost and bimatoprost/timolol fixed combination drops dosed in the evening
  • In study eye distance best corrected Snelen visual acuity greater than 1/10

Exclusion Criteria:

  • Contraindications to therapy with latanoprost, bimatoprost, or β-blockers
  • History of non-adherence or previously recorded evidence of lack of response (<10% morning IOP reduction) to any antiglaucoma medication
  • Patient can not understand the instructions and adhere to medications
  • Patient is a female of childbearing potential or lactating mother
  • Past history of trauma, inflammation, surgery, past use of steroids (within 2 months), severe dry eyes and use of contact lenses
  • Signs of ocular infection, except blepharitis, or corneal abnormality that may affect IOP measurements
  • The other eye can not receive the same therapy, or remain without medical therapy
  • Closed angles

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
24-hour IOP reduction between the two medications
Time Frame: 3 months
Bimatoprost/Timolol will obtain a statistically greater 24-hour IOP reduction than latanoprost and the mean 24-hour IOP difference between the two medications will be clinically meaningful (at least 2 mm Hg).
3 months
