Main objective

Scope: Safety, Efficacy

To confirm the clinical non-inferiority of a fixed-Combination Generic Formulation of Brimonidine0.2%/Timolol 0.5% eye drops, solution in single-dose container with the marketed preservative-containing Combigan® eye drops, solution in patients with open angle glaucoma, or ocular hypertension (IOP≥22 mmHg) by examining the change of IOP at 08:00 from end of study to baseline

Conditions and MedDRA coding

Open angle glaucoma is characterized by increased intraocular pressure, resulting in pathological changes in the optic disk and typical visual field defects,and eventually blindness

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 11

  1. Male or female, of any race and ≥18 years of age.
  2. Diagnosed of unilateral or bilateral open angle glaucoma or ocular hypertension
  3. Average IOP ≥ 22 mmHg and ≤ 35 mmHg measured at 08:00, 12:00 and 16:00 hours pre-treatment in at least one eye at day 0.
  4. Without treatment for open-angle glaucoma with IOP-lowering drugs, for at least 4 weeks.
  5. Best-corrected visual acuity ≥20 of 100 (Snellen) corresponding to logMAR of ≤0.7.
  6. No new systemic medication that may alter IOP in the previous 30 days (e.g. beta-blockers, Ca-channel-blockers, ACE-inhibitors, prostaglandins, etc.), or expected to continue the current treatment with these medicinal products on stable regimen for 30 days prior to the study and during the study.
  7. Patients with controlled arterial blood pressure according to the investigator’s opinion.
  8. Females who participate in the study are either unable to gestate [i.e. post-menopausal (absence of menses for 12 months prior to drug administration), hysterectomy, bilateral oophorectomy, tubal ligation at least 6 months prior to drug administration] or at reproductive age; Females of reproductive age if sexually active, must be practicing an effective method of birth control throughout the study; Reliable contraception methods are considered the following: • combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: oral, intravaginal or transdermal • progestogen-only hormonal contraception associated with inhibition of ovulation oral, implantable or injectable • intrauterine device (IUD) • intrauterine hormone-releasing system (IUS) • bilateral tubal occlusion • vasectomised partner • sexual abstinence
  9. Expected by the Investigator that IOP will remain controlled with the new treatment without optic nerve damage or progression of visual field loss;
  10. Able to understand the requirements of the clinical trial and to agree to return for the required follow-up visits;
  11. Willing to provide voluntary written informed consent and data protection declaration before any clinical trial related procedure is performed.

Exclusion criteria 27

  6. Intraocular surgery within the past 3 months;
  7. Ocular laser surgery within the past 1 months;
  8. Best-corrected visual acuity < 20 of 100 (Snellen), corresponding to worse than 0.7 logarithm of minimal angle of resolution (logMAR) score;

  20. Treatment with oral carbonic anhydrase inhibitors (e.g. acetazolamide, methazolamide, topiramate, sultiame, zonisamide);
  21. A history of allergic hypersensitivity or poor tolerance to any component of the eye drop solution used in this clinical trial
  22. Pregnancy or breast-feeding or childbearing potential not protected by a highly effective contraceptive method of birth control;
  23. Current participation or not yet completed period of at least 30 days since ending other investigational device or drug trial(s);
