Condition(s) targeted: Glaucoma

Intervention: Drug: bimatoprost/timolol fixed combination AM (Drug); Bimatoprost/timolol fixed combination dosed PM (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Aristotle University Of Thessaloniki

Official(s) and/or principal investigator(s):
Anastasios Konstas, MD, PhD, Principal Investigator, Affiliation: Head of the Glaucoma Unit


The objective of this crossover, randomized, placebo controlled, double-masked study is to compare the short-term (12 weeks) mean 24-hour IOP control and safety of the new fixed combination (bimatoprost/timolol, BTFC) given PM with placebo once in the morning, versus BTFC given AM with placebo once in the evening versus bimatoprost given in the evening in patients with exfoliative glaucoma (XFG).

Clinical Details

Official title: A 3-month, 4-centre, Crossover, Double-masked Study Investigating the 24-hour Intraocular Pressure Control With the Bimatoprost/Timolol Fixed Combination Dosed Morning, or Evening in Subjects With Exfoliative Glaucoma

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Crossover Assignment, Masking: Single Blind (Investigator), Primary Purpose: Treatment

Primary outcome: Mean 24-hour IOP

Secondary outcome: Side effects with medications

Detailed description: PRIMARY STUDY OBJECTIVES

- To show that the mean 24-hour IOP control obtained with BTFC (morning or evening) is

statistically better to that with bimatoprost monotherapy given once on the evening.

- To demonstrate that the fixed combination will provide a significantly better IOP

control in the morning when dosed in the evening.

- To test whether the mean 24-hour IOP control obtained with BTFC given once in the

evening may be statistically better to that with BTFC given once in the morning.

- To show whether there will be less 24-hour fluctuation of IOP with the evening dosing

of BTFC. STUDY POPULATION Consecutive newly-diagnosed, or suitably washed-out patients with exfoliative glaucoma (XFG) who exhibit a mean untreated IOP greater than 25 mm Hg at baseline (10: 00).


Minimum age: 39 Years. Maximum age: 81 Years. Gender(s): Both.


Inclusion Criteria:

- The patient is suffering from XFG (if the patient has bilateral XFG, both eyes will

be treated, but the worse eye will be selected for the statistical analysis)

- Patient is older than 39 years and younger than 85 years

- Patient is able and willing to participate in the study for the whole duration of the

follow up. Will sign the consent form.

- At screening the untreated IOP at 10: 00 (± 1 hr) is greater than 25 mm Hg and lower

than 40 mm Hg

- After bimatoprost run-in therapy the treated IOP at 10: 00 (± 1 hr) is greater than 19

mm Hg
