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

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).
