Brief Summary:
The objective of the study is to assess the efficacy and safety of T2347 (Latanoprost 0.005% + Timolol 0.5% unpreserved eye drops) versus Xalacom® in ocular hypertensive or glaucomatous patients initially treated, stabilised by Xalacom® or generics (fixed combination Latanoprost 0.005% + Timolol 0.5% preserved eye drops).

Condition or disease Intervention/treatment Phase
Open Angle Glaucoma Ocular Hypertension Drug: T2347 Drug: Xalacom Phase 3

Detailed Description:
Phase III, international, multicentre, randomised, investigator masked, 3 month duration, 2 parallel groups, 2 X 97 evaluable patients

Drug: Xalacom
Xalacom® 0.01% eye drop solution is supplied in 2.5 ml multidose container.
Other Name: Latanoprost 0.005% + Timolol 0.5% preserved eye drops




Primary Outcome Measures :
  1. Non-inferiority of T2347 Compared With Xalacom® on Change in Mean IOP at 9.00 am (± 1 Hour) Between the Baseline (Day 0) and Day 84 in the Worse Eye [ Time Frame: Day 84 ]

    the non-inferiority of T2347 unpreserved eye drops compared with Xalacom® on change in mean IOP at 9.00 am (± 1 hour) between the baseline (Day 0) and Day 84 in the worse eye.

    Two relevant time points are considered for this primary criteria: D0 and Day 84.

Criteria

Inclusion Criteria:

  • Signed and dated informed consent,
  • Male or female aged > 18 years old,
  • Both eyes with open angle glaucoma or ocular hypertension already treated and controlled by Xalacom® or generics (fixed combination Latanoprost 0.005% + Timolol 0.5% preserved eye drops) since at least 2 months.
  • IOP ≤ 18 mmHg in both eyes
  • History of IOP insufficiently controlled with first-line monotherapy based on the investigator judgement (e.g. non reaching the target IOP)
  • History of an add-on IOP reduction with Xalacom® or generics (fixed combination Latanoprost 0.005% + Timolol 0.5% preserved eye drops) in comparison with first-line treatment
  • Corneal thickness ≥ 500 μm and ≤ 600 μm in both eyes.

Exclusion Criteria:

  • Ophthalmic exclusion criteria (in either eye)
  • Fundoscopy, VF not performed or not available within the 6 months before inclusion visit.
  • Significant worsening according to the two last VF (minimum 6 months between these 2 VF)
  • Advanced stage of glaucoma:
  • Best far corrected visual acuity ≤ 1/10.
  • History of trauma, infection, clinically significant inflammation within the 3 months before inclusion visit.
  • Ongoing or known history of ocular seasonal and perennial allergy (SAC, PAC) and/or uveitis and/or viral infection.

    • Hyperaemia (Grade 5)
    • Superficial punctate keratitis (Grade 3)
    • Blepharitis (Grade 3)
  • Severe dry eye (defined by severe epithelial erosions of the cornea and/or use of dry eye medication with a frequency exceeding 8 instillations / day).
  • Corneal ulceration.
  • Palpebral abnormalities not related to medical treatment study and incompatible with a good evaluation.
  • History of corneal refractive surgery.
  • Any abnormality preventing accurate assessment e.g. reliable tonometry measurement, visual field examination.

Systemic/non ophthalmic exclusion criteria

  • Non-controlled diabetic patient.
  • Reactive airway disease including bronchial asthma or a history of bronchial asthma, severe chronic obstructive pulmonary disease.

Specific exclusion criteria for women

  • Pregnancy, lactation.

Exclusion criteria related to general conditions

  • Inability of patient to understand the study procedures and thus inability to give informed consent.
