Efficacy and Safety Assessment of T2347 Versus Xalacom® in Ocular Hypertensive or Glaucomatous Patients

Phase 3

Completed

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).

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

Recruitment & Eligibility

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)

Any medical or surgical history, disorder or disease such as acute or chronic severe organic disease: hepatic, endocrine, neoplastic, haematological; immunosuppressive, infectious diseases, severe psychiatric illness, relevant cardiovascular abnormalities, etc... and/or any complicating factor or structural abnormality, judged by the investigator to be incompatible with the study.

Specific exclusion criteria for women
